Do not wait until the freezing winter arrives to seal openings in your home. Rather, early warning signs can be seen. Be aware that over time, external aggressions such as wind, sun and rain degrade the quality of the caulking products on your doors and windows. Climate change, like freezing and thawing, makes the situation worse.
It is essential to call on building professionals if you notice that the caulking is dry, cracked or peeled off. The appearance of fogging on windows can also be caused by an insulation problem in your home.
A simple gesture can detect an air infiltration. Light a candle and pass it over all places where there may be an air leak. There is a draft if the flame simmers.
