Windows not only bring in light, but they also help retain heat, making them essential for home comfort. If you start noticing cold drafts, feel a chill, or see condensation inside the glass, it could be a sign that your window gaskets have worn out and are no longer working effectively. Replacing window gaskets quickly and efficiently restores insulation, improves comfort, and helps reduce heating costs. We replace gaskets in plastic and wooden windows throughout Lithuania; aluminium window gasket replacement is available in Vilnius and Kaunas only.
Replacing worn window gaskets helps your windows hold in heat better, insulate against noise, and extend their lifespan. It's a smart investment in home comfort.
Airtight gaskets protect your home from cold air, dust, noise, and moisture. When they wear out, windows no longer perform their function, which leads to:
That's why gasket replacement is one of the simplest and most effective ways to care for your windows and home insulation.
Window gaskets typically need to be replaced every 7-10 years, depending on their use and condition. They are one of the most important elements ensuring window airtightness in plastic and wooden windows throughout Lithuania; aluminium window service is available in Vilnius and Kaunas.
Gaskets most often wear out due to:
Recognizing worn gaskets is easy: they lose elasticity, crack, peel off, and cold air passes between the frame and sash. Due to leaky windows, up to 15-20% of room heat can be lost, so timely gasket replacement helps effectively save heating costs, especially during winter.
Our technicians perform gasket replacement for:
We use only high-quality sealing materials adapted to the local climate. We select gaskets according to the specific window profile to achieve maximum airtightness.
New window replacement is a more expensive and complex process, so in most cases, when frames and hardware are in good condition, it's enough to replace the gaskets for windows to be airtight again.
It's a smaller investment, work is done quickly, and the result lasts a long time. In short, it's a simple and effective way to renew window functionality without the need to replace the entire window system.
