Why caulking is essential in Quebec

Caulking is your home's first line of defense against cold air, rain and snowmelt infiltration. In Quebec, where temperatures can drop below -30 degrees Celsius in winter, failing caulking can lead to considerable heat loss and significantly increase your energy bills.

Caulking joints around your doors and windows endure extreme stress: repetitive freeze-thaw cycles, temperature swings of over 60 degrees between summer and winter, UV exposure and natural movement of the building structure. Over time, even the best sealant eventually degrades, cracks or peels.

Professional caulking done properly can last 10 to 15 years depending on the product used and exposure to the elements. It's a minimal investment that pays big dividends in energy savings and daily comfort. At Vosthermos, we exclusively use professional-grade sealants certified for northern climates.
