Window Sealing
Airtight windows help create a warm and comfortable home environment. Even windows in good condition gradually lose their original airtightness: gaskets wear out, hardware loses its adjustment, and air circulation causes drafts. Our specialists are experienced in sealing PVC, wooden, and aluminum windows and doors—including balcony and terrace doors. They quickly identify what needs to be done to restore proper function. Professional sealing significantly reduces heat loss, improves sound insulation, and increases comfort at home.
When is window sealing needed?
Windows should be sealed when you notice obvious signs of lost airtightness: feeling cold or drafts, condensation on the inside of windows, worn or cracked gaskets and sealants.
However, you shouldn't wait for problems to appear. Preventively, window airtightness should be checked approximately every 5-10 years, and if necessary - sealing should be renewed. This helps maintain effective home thermal insulation and avoid unplanned problems in the future.
Why choose sealing instead of window replacement?
Sealing is a faster and more economical solution than replacing the entire window. Usually frames are suitable, so it's enough to renew the sealing. This immediately improves thermal and sound insulation without major investments and complex construction work.
How is window sealing performed?
The technician assesses the window condition and determines where airtightness is lost. Old gaskets and sealants are removed, and in their place a professional sealing system is used:
- internal vapor barrier tape protects the joint from indoor moisture;
- elastic sealing foam ensures thermal and sound insulation and compensates for frame movement;
- external tapes protect the joint from weather conditions and drafts.
If necessary, the technician also adjusts the hardware so that the window presses properly against the frame and closes tightly. All work is done quickly and without additional finishing work.
