PVC windows are found in many houses and apartments, as they are easy to use, protect against drafts and have an aesthetically attractive appearance. It is important to know, how to adjust plastic windows, if you want them to last a long time. This can be done if you follow the instructions and use a special tool.
The most common breakdowns are:
- when closing the sash, the side and bottom parts come into contact with the frame;
- the need to replace the locking bar;
- poor fit of the sash;
- poor turn of the handle;
- failure or blocking of the window handle;
- open sash with locked mode and open window;
- a closed sash, with the window unlocked and the handle not working.
How to properly adjust plastic windows yourself
To adjust window fittings needed:
- special hexagon with a diameter of 4 millimeters;
- "stars";
- pliers;
- screwdrivers of 2 types (phillips, flat).
All plastic window sashes are adjustable on three sides. This makes it possible to achieve the desired position around the perimeter, in the sash, and also helps to strengthen the fit of the seal. Methods for setting up the operation of fittings and elements plastic windows many, so you can choose the most optimal one for yourself.
If, when closing a plastic window, the sash comes into contact with the bottom of the frame, the sash is directed upward towards the hinge. The sash swings open to make adjustments. From left to right, a hexagon is used to turn the screw, which is located at the end of the sash next to the top hinge, several turns (3 - 4). To adjust the fittings of a plastic window vertically, the sash must be closed. The protective cap is removed from the loop located below. Make 3-4 turns with the hexagon from left to right.
If the sash touches the frame when closing from the side, the sash must be moved towards the hinges. The side part of the sash, when it touches the bottom of the frame, is moved with a screw for adjustment to the hinge from below. Horizontal adjustment of the fittings is needed when the side of the sash is in contact with the frame; in this case, it moves up towards the hinge.
When the wear of the slats is checked, the window is opened and an inspection is carried out. A common option is to place the plank around the perimeter on all sides. When any strip wears out, an unevenness in the fit of the window sash appears. To correct this, the sash is opened, the caps are removed from the top and bottom bolts for adjustment, and the bolts are loosened. The screw adjusts the position of the window from above. Left and right, lower and upper position are adjustable.
At the end of the sash on the handle side there is a system of eccentrics (regulators). It regulates the degree of fit of the sash. The type of systems depends on the company of the installed window; the principle of operation is always the same.

When adjusting the pins, the eccentrics are turned with a hexagon. They help in adjusting the degree of contact between the frame and the sash. In hot weather, the fit of the valves should be weakened, and in the cold season - strengthened. The screw in the bottom hinge adjusts the degree of contact between the window sash and the hinges.
The hinge at the top is used to adjust the touch on both the tilt and swing sash. The bolt is located on the scissors near the top hinge. The window sash opens. A special lock is pressed. The handle needs to be ventilated. To ensure a tight fit of the sash, the bolt rotates from left to right. The fittings can be adjusted near the handle.
To ensure a good fit of the sash, the bar is shifted towards the street. The frame has mechanisms for pressing (on the hinge side), which allow you to adjust the fittings with a hexagon. The degree of contact of the sash depends entirely on the degree of extension of the tongue.

To prevent the mechanisms from deteriorating, the handle moves when the window is closed. To protect against the movement of handles in the open position of the window, window blockers are provided. They are located at the end of the sash under the handle. The window lock must be pressed before releasing the lock.
If the sash is in the closed position, and the window cannot be closed, the handle does not move, the lock requires adjustment. The sash is moved with a screw under the hinge from below towards the window blocker. The fastening is made weaker; a metal plate is inserted between the blocker and the frame.
If the handle is broken, it requires replacement. To do this, carefully pull the pad back and move it 90 degrees. The screws are unscrewed. The broken handle is removed. Another handle is installed. The cover is attached.
A common problem with the handle turning poorly is poor or complete lack of lubrication in the fittings. To avoid this problem, the mechanism is coated with any aerosol lubricant once a year. During the inspection, we must not forget to inspect the rubber seals.
It is quite possible to do all the adjustment work yourself if you put in a little effort. If in doubt, you can call a specialist and reduce the time, but spend money. How to adjust plastic windows yourself We suggest you look at the tutorial video. Try to do the housework yourself, then you can save your budget.
How to tighten plastic windows so that there is no draft from the sash? This question interests every owner of an opening double-glazed window. Indeed, in the cold season, even a small gap between the double-glazed window and the frame leads to a loss of comfort in the house.
How does the double-glazed window sash mechanism work?
A plastic window consists of a polymer frame (sometimes with a sash), a multilayer package assembled from 2-3 glasses separated by a void (air is the best heat insulator) and a mechanism that ensures the opening and closing of the window.
The mechanism of the sash allows you to open it by turning it on its hinges, or tilt it back, opening it at a precisely adjusted angle. To ensure these actions, the following components are included in the double-glazed window mechanism:
- The top hinge is a complex element that provides both rotation and tilting.
- The bottom loop is a simple element that provides only rotation.
- Constipation – complex knot, which both locks the sash and adjusts the functionality of the top hinge.
How the window will work - tilt or open - is decided by the constipation. When its handle (lever) is moved down, parallel to the side of the frame, the window closes tightly. Rotating the lever 90 degrees unlocks the swinging function - the window can be opened by pulling the handle towards you. Rotating the lever 180 degrees unlocks the tilting mechanism - the window will open slightly under its own weight or due to muscular force.
When do you need to adjust the window sash?
Firstly, adjustment is needed in case of errors during window installation. Insufficiently qualified craftsmen may make a mistake when checking the horizontal or vertical position of the glass unit, after which the sash will begin to scratch the frame. In this case, you will need a 2-3 mm adjustable gap in height and width.
Secondly, adjustment will come in handy after several years of window operation, when the seals lose their elasticity or simply wear out. The sash will be pressed against the frame, but the worn seal will no longer seal the joint. Then the millimeter adjustable clamping gap will come in handy.
Thirdly, manual adjustment of the gaps will be needed when the seasons change. In winter, everyone wants perfect tightness of the joints (so as not to blow), and in the summer, no one will refuse a slight draft.
Moreover, even in winter, before tightening the plastic windows, it is necessary to provide for the existence of a ventilation gap that ensures the flow of fresh air into the insulated room. Therefore, further in the text we will look at adjusting windows that blow either too much or too little.
Preparing a window for winter: how to adjust a plastic window so it doesn’t blow
If the sash scratches the frame, then in winter there is a blow from the window due to the distortion of the structure. To eliminate this drawback, you will have to do the following: slam the window and lock it with the handle. After this, grab the edge of the sash with both hands and pull it towards you, without offering much force. If it moves out of place at the bottom, then you have a loose bottom hinge. If it's at the top, you have problems with the top hinge.
After localizing the location of the displacement, you need to start eliminating the distortion. The loop at the bottom is adjustable both vertically and horizontally. In a similar way, you can adjust top mechanism. The tool usually used is a 4mm hex wrench. Sometimes a cross-head screwdriver or a special star wrench included in the window delivery kit is used.
To adjust horizontally, open the sash and insert the key into the groove located at the bottom of the hinge. Turning clockwise brings the glass unit closer to the hinge, turning in the opposite direction moves it away.
Vertical adjustment of the lower hinge is performed differently: the window is opened slightly, tilted into the room, the key is inserted into the groove located in the end part of the curtain. Turning clockwise raises the sash, turning in the opposite direction lowers it. After completing the adjustment, you can close the window and check whether the sash moves away from the frame or not.
The hinge at the top of the window is adjusted slightly differently. To do this, you need to open the window 180 degrees and get to the adjusting screw located on the side edge of the sash, in the area of the top hinge. Next, insert a key into the head of the screw and turn it a quarter turn. After this, close the window and check the degree of pressing of the sash again. If necessary, the operation is repeated.
If the screw at the top hinge does not help, then it is necessary to adjust another unit, which is located in the area of the tilt mechanism plate that holds the window in an inclined position. To do this, open the sash and, holding the lock, tilt it back, gaining access to the plate at the top of the window. Next, insert a key into the head of the screw and turn it a quarter turn clockwise or in the opposite direction.
To get to the tilt mechanism plate, you need to do the following: turn the handle 90 degrees, open the window, press the lock with your finger and turn the handle up 180°. After this, the open sash will tilt towards the room, exposing a plate with an adjusting screw.
If the sash closes easily and without squeaks and does not move when closed, but there is still a draft coming from the windows, tighten the clamp of the glass unit to the frame. To do this, do the following:
- Open the frame and turn the locking handle down. In this case, part of the metal pins protruding from the sash moves out of place. These parts must be marked with a felt-tip pen.
- Next, you need to take pliers (for smooth surfaces) or a flat-head screwdriver (for a slot) or an allen key (for an internal recess) and sequentially turn the pins so that most of them move towards the seal.
Typically, to create additional clamping force, the pins are turned clockwise half a turn. Moreover, until the manipulations with all the pins that move when the handle is closed are completed, the sash should be kept open. You will be able to evaluate the results of your efforts only after completing this work. Otherwise, the window will warp on the locking elements.
Adjustment does not help - change the seals
In particularly difficult cases, in order to eliminate an unwanted draft, in addition to adjusting the sash mechanism, it is necessary to resort to replacing the seals. To do this, you need to open the window and fix the sash. Next, grab the seal and pull it towards you. With enough effort it will come out of the groove very easily.
The next stage is the installation of a new seal. It starts with cutting to size. Moreover, the old seal acts as a template, so it cannot be stretched when dismantling. After trimming, the new material is pressed into the groove and checked for creases and other defects.
According to manufacturers' recommendations, such a replacement should be done no more than once every 10 years, but the seal could be installed unevenly or damaged due to use. Typically, the main cause of damage to the seal is abuse of the sash pressure setting. Therefore, sometimes it is changed before the end of the 10-year period.
If the seal squeaks, then instead of replacing it, you should try silicone grease - it will remove the unpleasant noise. In this case, it is strictly not recommended to use machine oil.
Preparing a window for summer: how to create a light draft
Before this, we figured out how to tighten the hinges on plastic windows so that cold air does not blow from the sash. Now we have to solve another problem - to create a light draft that will blow through the stuffy room. To do this you need to do the following:
First, find the trunnions on the side surface of the sash - the moving parts of the clamping mechanism. Their details protrude above the surface more than other elements.
Secondly, inspect the trunnions and find eccentrics - special screws screwed into the trunnions with a center offset. They will give themselves away not only by their slightly uneven location, but also by the presence of marks (marks) on the screw head.
Third, turn the off-center screw in the desired direction. The standard position of the eccentric is exactly in the center of the trunnion, which gives a medium-pressure force. However, in summer we need the weakest clamp so that fresh air can enter the apartment. Therefore, we rotate the eccentric so that its smaller side faces the rubber band (seal). Typically, this is done by turning the screw counterclockwise by half or a quarter of a turn.
The described operation will have to be done with all the trunnions, setting the eccentric marks in one direction, otherwise the sash will begin to mow when locked, and its mechanism will wear out prematurely.
Plastic windows have long established themselves as reliable and durable frames that preserve temperature regime premises and not allowing drafts to enter. Many people install plastic, but do not carry out maintenance and forget about the subtleties of use in the form of switching to seasonal mode and other necessary little things.
Correct adjustment of plastic windows and timely maintenance are the basis for a long service life, eliminating sudden expensive repairs.
Adjusting the sashes
Often, adjustment of window fittings is necessary when the quality of installation work is poor, when the structure is not aligned vertically and horizontally. It is also required in case of natural wear and tear, when the sashes begin to touch the frame and fittings. If the windows do not fit tightly, cold air begins to pass through and drafts appear. Instructions for self-adjustment of plastic windows will help you save a significant amount on the services of third-party specialists.
To work you will need simple tools:
- hex wrench;
- screwdriver.
Inspect the window to determine the installed fittings, since the adjustment will directly depend on this factor. In one case, the sash will need to be removed, in another, tightening the fastening screw will be sufficient.
Horizontal and vertical adjustment
On the horizontal side, the sash is subject to adjustment in the event of a bevel of the frame caused by shrinkage of the structure, incorrect opening of the window or loose fastenings of the fittings. To fix the problem, you need to insert a hex key into the upper window hinge, turning it clockwise until the sash moves a sufficient distance away.
In this case, the lower part of the opposite element should drop noticeably. The lower hinge is adjusted from the outside. The shifts average 2 mm.
Diagram of the main position correction points The window can be adjusted vertically using the hinge located at the bottom of the frame. The protective cap is removed from the loop and the rotational movements of the tuning mechanism begin. Moving the tool in a clockwise direction will raise the sash, moving it in the opposite direction will lower it.
Adjustment of plastic structures should occur smoothly so that the mechanisms move no more than 1 mm in one approach.
The sash stopped closing: problem solving
Adjustment of the pressure must be made when the window has difficulty moving from the open position to the closed position. Often the reason is the lock device, which does not allow the handle to be turned. The exact sequence of actions depends on the specific manufacturer. Some examples are equipped with a thin plate equipped with a spring on the inside, which must be pressed and the handle turned to close the window. Other copies are equipped with a tongue under the handle - when you press on it, the lock of the adjusted mechanism is removed.
If the sash stops closing, you need to unlock the lock In a situation where the window still does not want to close, minor repairs will be required. It is necessary to open the sash, find the element of the mechanism that serves as a hook for the tongue, unscrew and install a thin plate on the inside. The solution helps to shift the mechanism closer to the response element. As a result, the contact area will increase, allowing you to easily close the window.
Pressure density adjustment
Setting the pressure on a plastic window is quite simple if you follow a simple sequence of actions. Find in the area of the handle, located at the side end, a system of eccentrics that serve as the main adjustment tool.
Winter and summer mode can be adjusted using trunnions Their external design may be slightly different depending on the window manufacturer, but the principle of operation is the same, whatever their type.
Options appearance eccentrics 
When it is necessary to adjust the pressure on the side of the window hinges, you need to refer to the adjusting screw located on the bottom of the hinges. For tilt-and-turn sashes, additional adjustments are made using the top hinge.
In order to successfully get to the adjustment bolt located on the scissors next to the top hinge, you need to open the window, press the locking tab and set the handle to the ventilation mode. When it is necessary to press the sash against the window frame, the bolt rotates clockwise. Rotating in the opposite direction will weaken the seal.
By adjusting the tilt-and-turn scissors, you can adjust the degree of window pressure The method of adjusting window fittings depends on the manufacturing company, since there are varieties that are adjusted with screwdrivers located on the side of the handles. Others only fit hexagons. In order to increase the pressure, the bar is carefully shifted to the street side. If you look at the hinges, you will notice retractable clamping elements. A smaller extension will provide a loose fit, while a larger extension will press the sash tightly against the frame.
Cleaning the fittings from accumulated dust
Once every 5-7 years, windows need deep cleaning to remove accumulated dirt in hard-to-reach places. Without cleaning them in a timely manner, sooner or later you will have to repair them, since their functioning will be impaired. Repairs are quite labor-intensive in terms of the weight of the structure, so it is advisable to carry out the work with assistants.
Scheme for adjusting elements to keep them clean and tidy:
- remove the sash from its hinges, removing the overhead frame elements;
- remove the top axle;
- remove the sash from the lower hinges;
- carefully set aside.
Removal of elements must be done with an assistant The surface of the sash is carefully inspected and the screws attached to it are unscrewed. The mechanism parts are washed well, preferably using specialized solutions that are easy to apply with a brush. After this, the structure is dried well in the fresh air or with cold air from a hairdryer. Lubricant is applied to each driving mechanism. The fittings are assembled in the reverse order and installed in their original place.
Before assembling the window, all fittings must be lubricated. We repair window handles
Questions about adjusting window frames are quite often related to the operation of the handles, since from time to time they can break or lose functionality. It is important to remember that the handles of a plastic window require periodic attention, since more often than other parts they are subject to rapid wear: sometimes they require repairs or complete replacement.
Timely adjustment is the best solution to the problem of handles losing functionality. Thus, a fairly loose handle requires tightening of the fastenings, which can be done in a matter of minutes, since this breakdown is one of the most simple types repair work.
Find the decorative rectangular trim under the handle, lightly hook your fingers on both edges and turn 90°. There are a couple of bolts under the trim that need to be tightened with a Phillips screwdriver.
Under the decorative trim there are bolts that are tightened with a screwdriver You should not use tools to lift the plate covering the bolts, since there is a possibility of damaging the surface of the profile and disrupting the shape of the plug element.
Another common problem is the handle sticking, which periodically does not turn to the required angle. In this case, you need to lubricate the fasteners with machine oil using a cotton swab. A special spray or silicone lubricant will also work.
The problem of the handle sticking can be solved by lubricating the fasteners with oil. To replace, the handle is rotated 90° and the cover in the form of holding screws is removed. The unscrewed element can be easily replaced by installing the screws in the same sequence. Repair of plastic windows with complete replacement of fittings is inevitable if the handle is thoroughly jammed. Cases are extremely rare, but they do happen.
Do-it-yourself adjustment will not be difficult for owners, since the whole procedure is quite simple. It is only important to approach the setup with a degree of responsibility and strictly follow the instructions.

Most owners of private houses and apartments are interested in how to adjust plastic windows. You can configure them yourself without additional costs, which is why this option is attractive. Although modern designs Made using high-quality fittings, they sometimes require maintenance.
The sash is adjusted using a hexagon
Before you begin adjusting the window, it is recommended that you familiarize yourself with its basic elements. If during operation the smooth functioning of all components is not ensured, then there can be no talk of comfortable use of the structure.
Basic components
PVC window blocks usually include the following parts:
- frame made of plastic profile with steel reinforcement;
- doors that allow opening and closing;
- a double-glazed window, which is a product that is capable of transmitting light;
- bead holding the glass unit in the frame;
- an impost acting as a connecting post located vertically between the sashes;
- rubber seals ensuring tightness.
- shtulp used in conjunction with the above-mentioned element.
The moving elements can be lubricated with a can of WD-40, which is equipped with a convenient tube. Using an aerosol product, it will be possible to properly coat the parts with a layer of oil. It is recommended to lubricate during each seasonal adjustment, regardless of the serviceability of the part at a particular time.
Helpful advice! If regular handles are installed in the children's room, they can be replaced with products with a protective mechanism. A small child, even if he or she wants, will not be able to open the window on his own.

Metal-plastic windows have become an integral attribute of almost every modern home. For many, maintenance of plastic windows - repair and adjustment - is a fairly simple process. To perform these steps, you can watch a video that tells you how to set up PVC windows yourself, study the design of window fittings and have a minimum set of necessary tools.
Adjusting PVC windows does not require any complex special knowledge. You just need to study in detail the operating instructions for window fittings, which are provided with each plastic product or can be found on the official website of its manufacturer.
Tools and materials
To adjust and preventive maintenance of plastic products, a few simple tools are enough:
To prevent wear of the moving parts of the fittings and rubber seals, they must be cleaned and lubricated at least twice a year. To perform these operations, the following materials are required:
- Solutions for removing dust and dirt.
- Lubricant: machine oil, special impregnating composition.
- Silicone-based softener for rubber seals.
- Soft cloth, brush or brush, hair dryer with cold blow function.
Introduction to the structure of fittings
In order to independently repair a plastic window or adjust it, you need to know which hardware elements need to be used to solve specific problems that arise. The main parts involved in the operation of window fittings are:
- locking pins that regulate the degree of pressing of the sash to the frame;
- upper and lower hinges, responsible for moving the sash in horizontal and vertical planes;
- window handle that ensures the operation of the entire mechanism.
Before you start adjusting plastic window blocks, you need to find the location of all the necessary mechanisms on their sash. Clamping elements or locking pins are located along its entire perimeter and are round or oval protrusions. The hinges on which the window sash is attached to the frame differ in their structure and method of adjustment.
The direction of opening the sash has a certain significance in the process of setting up the operation of the fittings. Adjustment of the left and right loops occurs in the mirror direction. The handle is usually located in the center of the window sash and has 2-3 opening positions. The place where it is attached is covered with a decorative cover, which should move to the side quite easily.
Preventive Maintenance
To ensure long and stable operation of PVC windows, it is necessary to carry out preventive measures:
- Adjustment of window pressure winter-summer.
- Cleaning and lubricating all hardware parts subject to friction.
- Maintenance of sealing rubber.
Window pressure adjustment
Adjusting the degree of pressure of the window sash to the frame must be done due to the need to change the tightness of the window depending on climate changes and to prevent premature wear of the sealing rubber due to constant strong pressure.
To adjust plastic windows winter - summer, you need to prepare a suitable tool. Its choice depends on the shape of the clamping pins. For moving oval clamps you will need pliers. Depending on the shape of the hole on round clamping parts, use a screwdriver or a hexagon.
All plastic windows have three degrees of fit of the window sash to the frame:
- The middle (standard) clamp is set by default at the window manufacturing plant and corresponds to the central position of the trunnions. It is usually used in the autumn-spring period.
- Weak pressure ensures air flow into the room in summer due to the formation of microcracks.
- Strong pressure ensures complete sealing of the plastic product. It is installed during the winter cold.
The algorithm for adjusting the window by clamping is quite simple:
- All locking elements are found at the end of the open window sash.
- The tool turns the parts either clockwise (winter clamp) or counterclockwise (summer clamp).
- All clamping pins are adjusted identically.
- Close the sash and check the degree of pressure. The check can be performed using a sheet of office paper, which is placed between the sash and the frame. When pressed firmly, the sheet should not move. In the summer position of the locking mechanisms, the leaf can be pulled out from under the sash.
Cleaning and Lubrication
Window fittings are subject to natural wear and tear, which can occur faster due to improper use of the plastic product or untimely cleaning and lubrication. There are two options for cleaning the working mechanisms of PVC windows:
- Cleaning and lubricating parts accessible in the open or tilted position of the sash.
- Deep cleaning of the fittings with the sash removed from its hinges.
The second option is quite labor-intensive and requires the participation of two people, as well as certain professional skills. Therefore, it is better to entrust it to specialists.
The first option for cleaning plastic products is easy to do with your own hands:
Caring for sealing rubber
The seal (sealing rubber) is an important part of a plastic window, which ensures its tightness and reliable clamping. Rubber can lose its properties as a result of improper installation and use of the window, insufficient care, or become unusable over time.
To prevent this from happening, you must:
Replacing the sealing rubber on most windows takes little time and can be done by yourself. An important condition is to replace the damaged seal with an identical one, since products from another manufacturer may not fit the groove located on the window frame. To replace the old seal, use a screwdriver to remove it from the groove, and insert a new one into it. During installation, the sealing rubber is lightly pressed into the groove using a tool. After replacing the element, close the sash and check the degree of pressure and the presence of airflow between the sash and the frame.
Operational problems
Main problems problems that arise during the use of plastic window blocks are:
- blowing between the sash and the frame;
- sash sagging;
- incorrect operation of the window handle or its breakage.
Blowing
This problem is the most common when using plastic products. It occurs for several reasons:
- Poor quality of product or installation.
- The degree of pressing of the sash to the frame is incorrectly set.
- Sagging of the sash due to shrinkage of the building, during operation or due to its large mass and size.
All problems that arise with a plastic product during the warranty period must be resolved by the window company that installed the product. Especially if the problem is related to product or installation defects. Any independent intervention may become a reason for the seller to refuse warranty obligations.
There are many videos on the Internet with detailed instructions on how to tighten plastic windows so that it does not blow. Often, to eliminate a draft, it is enough to move the clamping pins to the winter position or change the seal. If, after these manipulations, the window continues to blow, then the problem is associated with sagging of the sash and a decrease in contact between the locking lugs and the strikers located on the frame. This problem requires a lot of effort, but can also be easily solved on your own after studying the instructions and watching the video tutorial.
Sagging of the sash
On the Internet you can find detailed instructions on how to adjust plastic windows yourself. The video tells in detail about the stages of work and the features of performing operations. Adjusting the window using hinges is carried out in several stages:
If, after making all possible adjustments to the sash, it still does not fit tightly to the frame, then you can try to repair the plastic window rather than adjust it yourself. To do this, use a screwdriver or screwdriver to unscrew the mating part of the locking latch in the area of the handle and place a gasket up to 4 mm thick under it. It must be made of plastic or wood. These additional elements are inserted into the side and bottom of the striker plate, which is put in place and screwed with a self-tapping screw.
Replacing and adjusting a window handle
The window handle is a wearing part of window fittings. During the operation of the window, it changes several times to a new or more functional model.
To replace the handle, you need to turn it to the position corresponding to the opening mode. After this, carefully, without using sharp objects, move the decorative trim to the side and unscrew the fastening screws using a screwdriver. Rocking it slightly, remove the handle from the hole and replace it with a new one, performing all the above steps in reverse order. When purchasing a new handle, it is important to take into account the width of the profile system, since the length of the pin of the required product will depend on this. If this value does not correspond to the width of the sash profile, the handle will not work correctly, which will lead to its rapid wear and problems with the functioning of the fittings.
In some cases, it is not replacement but adjustment of a loose handle that is required. To do this, move the decorative trim aside and tighten the fastening bolts with a screwdriver.
It will become much easier to independently adjust PVC windows if you carefully study the simple instructions and watch videos made by professional window installers. However, in the event of a serious breakdown, it is imperative to seek the help of qualified technicians. This will help avoid major complications and save your budget.
