For all work performed
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.
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.
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.
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:
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.
We take our work seriously and always focus on practical, long-term solutions based on the current window situation.
