What kind of accessories are there?

The market offers a wide variety of window parts. Experts will help you choose what to choose in each individual case. Most often, fittings are distinguished by the method of opening the sash:

• Rotary . This species has been used for more than one generation. But every year it is constantly being refined and improved to make using Euro-windows as convenient as possible.
• Folding or “fanlight”. With this opening, window fittings for windows fix the opening of the sash in the desired position. During production, it is recommended to equip the product with limiters.
• Tilt and turn . Such window fittings allow you to simultaneously open and tilt the sash. The mechanism, which is a closed structure, is controlled using a handle.

The functionality of the mechanisms is increased by adding additional elements. For example, using a rotation limiter, you can fix the sash at different angles. Turn blockers are needed in rooms with children. These elements prevent the doors from opening completely if they are tilted for ventilation. The use of a microlift increases the service life of Euro windows, as it reduces the load on the hinges.

What kind of mechanism

On plastic structures you can often find a tilt-and-turn mechanism. It is the most convenient, and therefore manufacturers install it.

To operate the mechanism, install one handle. Usually, if it is down, the tilt window is closed. When turned to the side, it opens.

To open it slightly at an angle or for ventilation, just lift the handle up and pull it towards you.

You can install such a mechanism yourself. To do this, you need to figure out what components it consists of.

For assembly you will need:

• traction;
• connecting elements;
• brackets;
• loops.

This is a basic list of required elements. They will provide the functionality of a tilt-and-turn window. In addition to them, you will need other accessories, which also play an important role.

When choosing a window profile with such a mechanism, there is no need for additional installation of vents, since the device takes on this function. It turns out that the entire opening will be occupied by a double-glazed window. It's more functional, convenient and looks better. In addition, more light enters the room.

The principle of operation is that when you press the handle, the locking pins are set in motion. They begin to work due to the force that passes through the transmission rods.

Our advantages

Diagnostics of breakdowns

An on-site specialist will detect malfunctions in the operation of mechanisms (for example, distortions of the sashes), the integrity of double-glazed windows, and check the tightness of the seams.

Urgent repairs

Such work is carried out in case of serious defects in windows, in cases where it is necessary to replace damaged or worn parts.

Sealing and adjustment

If depressurization of seams or a violation of the geometry of the window structure is detected, the technician performs adjustments and eliminates faults.

Preventative work

The fittings and locking devices are lubricated and cleaned of dirt.

What to do if the main lock gear is broken?

If the sash gearbox is broken, you need to contact a plastic window repair company and call a specialist. He will select the necessary fittings and repair the window. If the windows were recently installed, then it may be possible to get by by replacing only the main lock. But experience shows that the gearbox breaks when the window is more than 10-15 years old. Therefore, it will be difficult to choose exactly the same fittings, since many manufacturers periodically update their products and stop producing old models. We also wanted to draw your attention to the fact that after 10-15 years, if one of the fittings elements breaks, then most likely other elements will soon begin to break as well. Therefore, for the sake of economy and practicality, it is advisable to immediately change the entire window trim.

Additional hardware repair services

Sometimes it happens that even the most reliable parts break, then it is necessary to replace the fittings or repair them.

The following malfunctions of PVC window parts are identified:

• The appearance of gaps . The main reasons are incorrect adjustment or it’s time to change the seal. In this case, there is no need to repair any elements. It is enough to glue a new seal and make the correct adjustment.
• The shut-off valves do not work . With prolonged use, the sash may stop closing normally. This is explained by the fact that the mechanism has failed due to wear. In this case, you need to replace window fittings; in Samara, our company specializes in replacing broken elements and prices start from 500 rubles. Or you can do the repairs yourself.
• Handle jamming . The locking mechanism may jam if the lock is not adjusted. It does not work correctly and opening is problematic. Sometimes parts of the handle break, then it needs to be replaced.

You can repair a window yourself if you have special knowledge and ability to use the necessary tools. If you don’t have the ability or desire to repair window fittings yourself, it’s better to trust the professionals.

In any case, regardless of the severity of the damage caused to the fittings or window, the specialist of our company will be able to quickly eliminate them.

Features of plastic window fittings

Window fittings are a complex mechanism consisting of a main and middle lock, an angular gear, folding scissors, as well as upper and lower hinges. It is this part that is subjected to regular load when opening and closing the window, so special attention should be paid to the choice of this design.

To purchase high-quality window fittings, you need to look at the following characteristics:

• wear resistance : the window mechanism is designed for approximately 10,000 openings and closings;
• ease of use : the simpler the design, the less likely it is to break;
• absence of corrosion : before purchasing plastic window fittings, inspect all its elements and make sure that none of them have formed corrosion;
• possibility of further reinstallation : it is advisable to choose standard window designs, the replacement of which does not require much effort and additional financial costs.

Components of window fittings

1. Basic constipation
2. Angular gear
3. Folding scissors
4. Moderate constipation
5. Top hinges
6. Bottom loops

In addition to the internal mechanism, there are a number of elements with the help of which the window is directly opened:

• window handle;
• strike plate;
• opening limiter (comb).

Repair or replacement of fittings: what is necessary in your case?

In some situations, replacing window fittings can be prevented by repairing its individual elements. At the same time, there are cases when the design is beyond repair. A specialist is ready to come to you and suggest how to solve the problem in your particular case.

When replacement and adjustment of fittings is required

• Violation of smooth opening and closing . Perhaps you only need to clean and lubricate the fittings, but a more serious reason may be discovered.
• Sagging or distortion of the sash, its loss . It is necessary to inspect, adjust and, if necessary, replace hinges and adjacent components.
• Broken handle . One of the most easily fixable problems when it comes only to the handle itself. However, more serious problems are possible, because the entire opening/closing system is tied to it.
• Blowing with the window closed . The reason may be either a worn-out seal or the mechanism itself.
• You can also contact us if you decide to expand the functions of the window: install a child lock (baby-stop), install a handle with a key, a comb, or replace the rotary mechanism with a tilt-and-turn one.

Replacing fittings is not only a method of eliminating breakdowns, but also a good reason to update the functionality of the window. You can express your desire to our master - he will draw up an individual plan for modernizing the window.

Difficulty manipulating the handle

There can be only two reasons for difficulties in manipulating the handle:

If there is sagging, it should be removed in accordance with the method described above. If there is no sagging, then the problem is certainly the state of lubrication. It should be remembered that the internal mechanism of plastic windows is very complex, and the handle is the only control that operates a large number of different components. All this mechanics with its numerous joints can work flawlessly only if it contains clean and high-quality lubricant. Therefore, it is always necessary to have a universal lubricant or one specially oriented for window fittings on hand. This will allow periodic lubrication of all moving components and elements present in the mechanism of the window structure.

If after performing the manipulations the handle does not move better, it makes sense to call a professional.

Is it possible to replace the fittings yourself?

While it is possible and even necessary to adjust the fittings yourself, we do not recommend carrying out major work. There are several reasons for this:

• Installation of non-native fittings . Each type and brand of windows is suitable for special types of fittings; non-native ones may simply not be suitable. Even if you install them, it is the new elements that will lead to the speedy breakdown of the old ones.
• Installation subtleties . It only looks easy and simple from the outside; in fact, even to correctly replace a window handle, you need to know how to “approach” it.
• Loss of warranty . Third-party intervention is usually the main reason why window manufacturers refuse warranty obligations.

How to repair the main lock reducer yourself?

Let us say right away that it is impossible to repair the gearbox on the main window lock. It is necessary to completely replace the constipation. Choosing the right window fittings on your own is also very difficult; we have already written about this several times on the pages of our website. It is more economical and profitable if the repair of the plastic sash is carried out by a specialist. Since in addition to the brand of fittings, you need to know its series and overall dimensions. The hardware manufacturer also plays an important role. Properly installed German fittings will serve you for decades.

Next, you need to remove the broken fittings from the sash and install new ones. Even for an experienced craftsman, replacing window fittings takes an hour. We have had cases where clients tried to fix the window themselves. It all ended at the stage of removing the sash from its hinges and disassembling it. Almost no one was able to install the fittings independently and correctly. Or it took more than a single day. Therefore, we strongly recommend that you save your nerves and seek help from specialists.

You can call a technician if the main locking gear of a plastic window breaks down by phone every day from 9:00 to 21:00. A specialist repair visit is free!

Replacing gaskets

Repair of plastic window mechanisms, repair and replacement of their fittings should be carried out as the window structures age. This provision fully applies to sealing gaskets. They should be replaced on average every 10 years. However, the condition of the gaskets is easily noticeable during normal visual inspection, so they should be replaced immediately if signs of aging are detected.

Before replacing, you should purchase a new sealing gasket, giving preference to German ones, which are of higher quality and greater durability. Replacing this element begins with removing the old seal from the frame groove. Then, the rubber cord of the new product you purchased is slowly inserted into the groove that has been previously washed and lubricated with glue so as to prevent it from being stretched or compressed.

So, we have told you about the main malfunctions of plastic windows, which can be eliminated on your own. If the defect in its functioning turns out to be more serious, we recommend seeking professional help from specialists engaged in this type of activity.
