Window caulking during winter, here is what you need to know.

Cold air drafts may indicate that your door or window caulking joints are due for replacement.

As winter gets closer and the temperatures outside start to drop, you may feel the autumn cold air drafts entering through your windows or doors. Air leaks may be a sign that your door or window caulking is deteriorated or cracked and needs to be replaced.

Is it possible to caulk your home during the winter?

The best way to stop cold air from entering through your window is to seal your window. Some sealants can not be applied at cold or freezing temperatures, as they freeze or do not stick to the surfaces.

However, The waterproofing industry has been going through a huge technological advancement in recent years. Top-quality sealants are manufactured to endure and be applied in extremely cold or hot weather (-20C to 40C). As a result, caulking services can be offered all year round.

Caulking before or during winter is possible and recommended if the sealants around your home are deteriorating. There is no need to feel uncomfortable in your home when the solution is so simple.

The sealant application is not affected by cold weather- It is affected by wet weather.

While Silicon-based caulk can be applied in icy weather without freezing or unsticking, it can not be applied on wet or moist surfaces. Caulking loses its adhering properties when applied to extremely wet surfaces. Therefore, sealing a home can be done all year round except for on snow or rainy days. In winter, snowfall does not happen every day, and therefore, caulking commercial, residential and industrial buildings are possible.

At calfeutrage Apex, we caulk residential and commercial buildings during winter, when it doesn’t rain or snow heavily.

Advantages of caulking homes in winter.

By caulking windows and doors during winter, you will be able to enjoy cozy evenings by your window without feeling cold.

Besides, if your sealants are faulty, it’s better to replace them as soon as possible to avoid water infiltration. Water infiltration is often discovered during spring, as the snow is starting to melt and water seeps through gaps and cracks. By the time the infiltration is discovered, the damage to the structure could be extensive.
