- a thing is not eternal. They serve for a long time and regularly, especially with proper operation. The design of such windows practically does not differ from wooden ones, however, in plastic windows there are rubber compressor.
Many people think that the seal does not need to be changed, and if it is necessary, then only with a major replacement of the entire window. This is not true. When it comes to replacing the seal, it is important to understand that this can be done with your own hands or with the help of a master.
The call of the master and his work, of course, will be paid. Therefore, those who want to save money can do this simple procedure on their own. So, when do you need to replace the seal on the plastic window? Typically, replacement is carried out after wear, and this averages two years, give or take a few months.
On a window poorly protected by a sealant, all sorts of unpleasant manifestations are observed. For example, if it is raining heavily, water starts to flow from the bottom of the frame, and if it is cold outside, the seal also freezes. It is also necessary to replace the interlayer in the case when the seal has changed shape, become uneven, has damage, that is, its integrity has been violated.
A sign of a faulty seal can also be poor sound insulation, a draft even when the frame is closed. Causes of damage to the seal: temperature changes (temperature difference outside the window from the inside), severe frosts, improper care of the frame as a whole, too high humidity.
To replace sealant, you only need three 
object is directly a new sealant. which can be bought at construction markets or in construction stores, glue and rubber scissors. The old seal must be separated from the window, and then thoroughly wipe the vacated space with a rag. You can wash with warm soapy water, but then wipe dry so that not a single drop of water remains on the surface.
The old seal cord is removed completely, and a new cord is also inserted in its place. The cord sits on a special glue, you need to do this quickly and carefully until the glue is dry. The cord cannot be cut, otherwise the whole point of installing a new seal will be lost. It is also necessary to monitor the cleanliness of windows, dirty windows wear out faster, the seal wears out and deforms faster.
Replacing the seal in PVC plastic windows necessary if you begin to feel a draft in the room.
Window gum is a special material that ensures the tightness of the junction of the sashes to the frames. With active use, the seal is subject to mechanical damage and rapid wear.
Also, the window seal, regardless of whether it is rubber, silicone or rubber, loses over time
elasticity, as a rule, needs to be replaced after 7 - 10 years of operation of windows.

Replacing the seal in plastic windows is the only way to eliminate heat leakage at the junction of the sash to the frame.
Employees of our company first make an external inspection and select the required brand of rubber seal.
When performing operations on PVC profiles, only original components from the respective manufacturer are used. During installation, no accelerating devices are used, the use of which can damage the rubber band. The process is carried out for both the outer and inner contours at the same time, only in this way can the quality be guaranteed.
From the outside, this operation does not look too complicated, some try to perform it on their own. However, there are a lot of subtleties here, and therefore often such attempts lead to even greater drafts through unprofessionally installed elements. Do-it-yourself replacement is usually done to save money, consumers buy cheap components, which only exacerbates the problem.
Materials are sold in bulk in large quantities up to 500 m. They are intended for enterprises producing windows and doors, or companies involved in their installation, maintenance, and repair. In retail, their price is quite high and the client cannot get any benefits from self-replacement.
All PVC double-glazed windows: Veka, KBE, Rehau, as well as other manufacturers, have their own systems with their own tolerances. The use of non-original seals only worsens the overall design characteristics. This is easy to understand from the following example:
It would seem that if you install an elastic band of greater thickness, this will eliminate the influx of cold air from the outside.
But at the same time, the load on the locking elements greatly increases, which often leads to adjustment violations and even system breakdowns.

Replacing the seal on plastic windows with your own hands is done in most cases without problems. This is a simple procedure that anyone can handle. Next, we will consider all the features of this operation.
The sealing of the double-glazed window depends on the sealant. You can understand that it is out of order if the following factors began to appear:
- The window began to freeze through - frost appears inside.
- There is condensation on the glass. This is due to the fact that the sashes began to close poorly.
- The rubber has worn out. This is due to a too long operating period.
- A draft began to circulate in the room. It appears as a result of depressurization.
If at least one of these factors appears, the replacement of rubber bands on plastic windows should be carried out immediately.
What are the varieties
Many people wonder which window seal is better? To answer this question, you should know all its varieties. They differ not only in external features, but also in the materials from which they are made. The most popular options are:
- Rubber (produced by vulcanization of rubber with the addition of sulfur). In the recent past, the most popular variety. With an affordable price, such an element is able to seal all joints
- EPDM (from various polymer compounds). Operational period - 20 years. It is characterized by high resistance to atmospheric factors (does not crack even at very low temperatures).
- Silicone. Can last up to 40 years. Used for both residential and industrial premises. The main advantage is absolute environmental friendliness. Does not lose its properties even with sudden changes in temperature. Resistant to UV rays, oxygen and ozone.
- TPE (thermoplastic elastomers). Created as a result of the improvement of its silicone "brother". Possesses the increased operational characteristics. Now this is the most popular category.
- PVC. Such an element will last no more than 3 years due to modest technical characteristics. However, it can only be used in warm rooms. The only advantage is the very low price.
Maintenance rules that will increase the operational period
Timely lubrication of the window seal prolongs its life several times. Despite the fact that this element is made of very high quality and durable materials, it still wears out over time. To make this happen as late as possible, special lubricants are used that protect the element from the harmful effects of external factors.
How to lubricate seals? There are several options that are excellent in their cost and effectiveness:
- Glycerin is the cheapest option. This colorless liquid is sold in a pharmacy and costs around 20 rubles. It is excellent for lubricating PVC surfaces, covering them with an invisible protective film. A significant drawback is that glycerin dissolves in water, so there are no waterproofing properties.
- Petrolatum. This is a universal lubricant that covers the surface with a transparent layer. However, it can only be used for rubber models. Vaseline softens them, making them more pliable. It is completely hydrophobic, so the material will be perfectly protected from moisture. The only negative is the small operating temperature range from -25 to +28 degrees. In most regions of our country, the climate is harsher, so Vaseline will not last long.
- WD-40. The most popular lubricant in the world, which is used in all areas. It is based on mineral oil, which protects the surface from moisture. The presence of carbohydrates in the composition reduces viscosity. WD-40 is sold in spray cans, so it is convenient to use.
Interesting: WD-40 was developed to protect spacecraft hulls from corrosion and other external factors.
We make the replacement correctly and without consequences
- Having bought a tape that suits you, we stock up on special glue. You will also need rubber scissors.
- Remove worn tape. This is easy to do - with a slight effort, it is pulled out of the grooves.
- Next, we clean the original surface. It is necessary to completely get rid of dust and dirt in order to ensure maximum adhesion of the adhesive. Ideally degrease the surface. To do this, we use alcohol, white spirit, solvent or other similar substances.
- Then evenly coat the perimeter of the frame with glue. Then we insert a new seal necessarily entirely. If you have never done this before, we advise you to practice doing it without glue first, as many people have problems at this stage. Do not pull the tape or over-compress it - it must be in a free state.
- Having laid the tape correctly, cut off the excess. Lubricate additionally the junction.
Perform this procedure regularly to ensure a good indoor climate.
They have firmly entered our lives, because thanks to them, much more heat is stored in houses than when installing wooden counterparts. But what to do if, as a result of any reason, you began to feel that they are not doing their job very well: a draft has appeared or the room is noticeably colder. In this case, it is not necessary to think about buying a new opening. Indeed, in most cases, a simple replacement of seals on plastic windows will help to cope with the problem. You will learn how this is done and what materials will be required for such work from this material.
When is it necessary to replace seals on plastic windows?
The quality of the sealing of the opening depends on the condition of the rubber gaskets that ensure a snug fit between the doors. And there are several signs that it's time to do a little plastic window repair. Replacement of the seal is necessary in such cases:
- In winter, frost appears on the inside of the window block and the window sill.
- A draft began to walk around the apartment.
- Decreased sound quality.
- There is condensation on the glass.
- There is fungus or mold on the window sashes.
Any of these signs suggests that urgent replacement of seals on plastic windows is necessary.
Choosing a material
There are many varieties of gaskets for plastic windows. And each type has its own characteristics and cost. In order for the replacement of seals on plastic windows to bring as much benefit as possible and at the same time not hit your wallet, you need to learn about all types of such material:
- Rubber compressor. Such material is made from rubber with the addition of sulfur. Such a gasket is quite cheap, while it can last up to 30 years.
- Silicone seal. The most environmentally friendly material that can last about 40 years. Such a seal can be used both in residential and industrial premises. At the same time, it does not deteriorate from sudden changes in temperature, as well as from the action of UV rays, oxygen or ozone.
- Polymer sealant (EPDM). The most expensive, but at the same time reliable option. It can withstand the lowest possible temperatures, while not cracking and retaining its shape. Service life - 20 years.
- Thermoplastic elastomer (TPE). Advanced silicone sealant with increased resistance to temperatures and mechanical stress. Today it is the most popular material, despite its rather decent cost.
- PVC. The cheapest material with modest technical characteristics. Warranty period of service - 3 years. It is recommended to install a PVC gasket only in warm rooms.
Do-it-yourself replacement of the seal in plastic windows. Preparation for work
After stocking up on the necessary materials, you will need to prepare the windows for the replacement of heaters. First of all, you need to remove the old gaskets. It will not be difficult to do this, because the heaters are easily removed from the grooves. Next, you need to get rid of dirt and dust on the surface of the valves with a soft cloth or sponge soaked in soapy water. The next step is to degrease the window. For these purposes, you can use alcohol, solvent or white spirit.
main stage
Replacing rubber seals in plastic windows is a rather laborious process that requires a little skill. So if you have never done anything like this, then practice on a small section of the frame. After you have cleaned and degreased the windows well, the grooves in which you will lay the insulation must be well greased with glue. After that, you need to insert the entire gasket, while making sure that the material is not stretched or compressed. This is where the previous training comes in handy. After you have laid all the insulation, it remains only to cut off the excess material and additionally grease the joints of the gaskets with glue.
Call a specialist
Adjusting plastic windows, replacing a seal - all these actions will require great accuracy and skill from you. So if you are not confident in your abilities, then it is better to invite a specialist who will perform such work in the shortest possible time and for a small fee.
How to increase the life of seals
Despite the fact that gaskets for plastic windows are made of durable materials, they still wear out over time. To make this happen as late as possible, it is necessary to periodically lubricate the seals. You can do this several times a year, and this approach will help extend the life of the gaskets. What can be used as a lubricant:
- Glycerol. The cheapest and most practical material that can be purchased at any pharmacy. The only drawback is that glycerin dissolves quickly in water, so it cannot provide special waterproofing.
- Petrolatum. This lubricant can only be used on rubber seals. The advantages of this lubricant include the price and water resistance, the disadvantages are the small temperature range that it can endure (from - 25 to + 28 ° C).
- WD-40. The most popular mineral oil, which will perfectly protect the surface of the seal from moisture and mechanical damage. In addition, this tool is sold in spray cans, so it is very convenient to use it. The only downside is the price of the product.
- Silicone Grease. Operating temperature range from -50 to 230 °C. In addition, this lubricant perfectly protects the seal against wear. The only downside is the high price.
- Professional set. The best option for protecting window gaskets. Such a complex is specially designed to protect heaters, and for a long time keeps them in their original form. But such a set is very expensive.
Replacing seals on plastic windows, as well as caring for them, will allow you to maintain a microclimate in your apartment. The main thing is to do everything correctly and according to the instructions. And then warmth and comfort will reign in the house for a long time.
In just a few years, plastic windows have become quite widespread. This fact is explained not only by their practicality, but also by functionality. Metal-plastic structures fit perfectly into any interior and at the same time do not require special care. Of course, in some cases, it is necessary to replace some elements, for example, rubber seals.
When to change
Replacing seals on plastic windows is a simple process that you can do yourself. But at the same time, not everyone knows when to do it. The service life of the structure directly depends on the quality of all components: seals, double-glazed windows, fittings and profiles. Each element performs its functions. But if something becomes unusable, then the window stops opening or closing normally.
Most often, problems arise due to the poor quality of rubber seals. But it is these elements that ensure a snug fit of the structure doors to the frame. If the window is used for too long, it may be necessary to replace the plastic window seal. Over time, these elements can lose elasticity, dry out and crack. If the metal-plastic construction is often used, then the insulating properties of the seals are lost. The service life of these elements is from 3 to 5 years. Then they need to be replaced.
The main signs of a malfunction: drafts, condensation on the glass surface, freezing. In the latter case, frost can be seen on the inside of the window, formed as a result of severe frost. The service life of a rubber seal depends not only on how plastic windows were cared for, but also on climatic conditions.
Preparatory work
In order for the replacement of seals on plastic windows to go without problems, it is worth preparing the window in advance. First you need to remove the old material from the grooves. In this case, there will be no problems, since the seals are very easy to remove, and no special efforts are needed. After that, the surfaces of the structure must be cleaned and degreased. Dust and dirt must be removed. In this case, the use of abrasive substances is not worth it. Remove dirt with a soft cloth or sponge.
For those who do not know, the rubber seal is a black cord that has a figured or tubular section. It depends on the type of product. It is this element that is responsible for the microclimate in the room. It depends on the quality whether it will be warm in the house, or whether the window will blow through.
Replacing seals on plastic windows allows you to get rid of drafts, condensation and ice. However, experts recommend using material from European manufacturers, since Chinese or Turkish counterparts are of poor quality.
What will be required
Replacing rubber bands on plastic windows with your own hands will be done much faster if you prepare all the tools and materials in advance. For repairs you will need:
- Special scissors for rubber products.
- Seals for structures.
- Glue for rubber. You can also use special formulations.
When everything is ready, you can repair plastic windows.
main steps
When the surfaces are cleaned and prepared, you can begin to replace. To begin with, it is worth smearing all the corners of the frame with adhesive. After that, new sealing gum can be placed in the grooves. In this case, it is worth considering that you need to insert whole pieces, and not individual segments. Of course, without experience and certain skills, this is not so easy to do.
Replacing seals on plastic windows must be done carefully and in compliance with certain requirements. When laying in the grooves of the material, it must not be pulled, and also strongly compressed. Sealing gum should lie evenly around the perimeter of the window.
When the material is laid, carefully cut off its tip. The joint of the sealing rubber bands must be carefully glued.
Finally
If you are not confident in your own abilities, then you should seek help from specialists. After all, replacing rubber seals is a laborious process that requires skill and accuracy. Professionally performed work is a guarantee of warmth and comfort in your home. In addition, this will save money and, of course, nerves.
