Windows can be replaced at any time of the year. Whether is it sunny or rainy or snowing outside. But they are some challenges that might happen during a very cold or wet and rainy day. Windows can be installed in winter and even temperatures up to -20C. Of course, some difficulties can come up during the installation. For example, cutting the vinyl in new windows will get harder specially for windows that need many cuts such as bay windows, for these kinds of windows, it is better to wait until spring for their replacement. Moreover, in many cases, the replacement is possible during rain but this will again depend on many things. For example, extreme wind and heavy rain can make the replacement difficult because it can cause safety issues for the installation team. Also, heavy rain can cause moisture to enter your house which we are trying to prevent mostly by replacing a high-quality window. Our installers are experienced for doing the replacement in all kind of weathers and if the weather condition is very bad, they can always reschedule to complete the replacement process
