Draught Through Plastic Windows – What to Do?

Cold air coming through plastic windows is usually the first sign that they have lost their seal. Most people only notice the problem when temperatures drop and a draught appears near the windows, home comfort decreases, or heating costs start to rise.

The problem is most commonly related to worn gaskets, reduced window compression, or long-overdue window maintenance. Timely window sealing or repair helps reduce heat loss and avoids more extensive repair work in the future.

Why Is Cold Air Coming Through Plastic Windows?

Even high-quality plastic windows wear over time. Temperature fluctuations, humidity, sunlight, and constant opening and closing gradually affect window fittings and gaskets. As a result, the window compression becomes less effective than before and cold air begins to enter.

The most common causes of reduced sealing are worn window gaskets, reduced compression, or an unevenly pressing sash. In some cases, the problem arises from long-overdue adjustment or natural fitting wear.

How to Tell Your Windows Need Sealing

The first signs of reduced sealing usually appear gradually, so many people don't notice them immediately. The problem typically becomes apparent when temperatures drop or the heating season begins.

It is worth contacting professional technicians if you feel a draught near the windows, cold air is coming through, the glass is steaming up, or moisture is accumulating. Another common sign prompting people to seek window sealing in Klaipėda is higher heating bills or increased outside noise.

In these cases, professional plastic window sealing or gasket replacement is usually required.

Do You Always Need to Replace the Gaskets?

Not always. Sometimes the problem arises from reduced window compression or misaligned fittings. However, if the gaskets have hardened, cracked, or lost their elasticity, adjustment alone is usually no longer sufficient.

Professional technicians first assess the condition of the gaskets, the operation of the fittings, the window compression, and the overall seal. Only after diagnosis is it possible to determine accurately whether adjustment is needed or whether window sealing and gasket replacement are already necessary.

How to Reduce Heat Loss Through Windows

One of the most effective ways to reduce heat loss is timely plastic window sealing. In some cases, additional internal window sealing is carried out to reduce draughts and improve the overall seal indoors. Properly maintained and well-sealed windows reduce draughts, improve home comfort, and allow a more stable temperature to be maintained indoors.

Well-sealed windows also help reduce moisture accumulation and protect fittings from faster wear. In most cases, professional sealing costs considerably less than a later larger repair or new window installation.

When to Call a Professional

Although people sometimes try to carry out minor adjustment work themselves, incorrect fitting adjustment can further reduce the seal or damage the mechanisms.

Professional window technicians can accurately identify the cause of the problem and select the most suitable solution for the specific window system. In most cases, professional adjustment, gasket replacement, or additional window sealing is sufficient to restore the seal and smooth operation.
