Door and Window Caulking
Professional caulking service for doors and windows. Prevent air and water infiltration around your openings with premium sealant products. Quality caulking is essential to face Quebec winters and reduce your heating costs.
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.
Signs it's time to redo your caulking
Several clues may indicate that your caulking needs to be redone. The most obvious are visible cracks, peeling or crumbling of the existing sealant around your windows and doors. If you notice mold along frames, excessive condensation on your windows or cold drafts near your openings, these are clear signs of failing caulking.
Other signs are less visible but equally important: an unexplained increase in your heating bill, temperature variations from one room to another, or water infiltration marks around window frames. Even if your caulking appears intact, it may have lost its elasticity and no longer properly fulfill its sealing role.
We recommend a visual inspection of your caulking at least once a year, ideally in the fall before cold weather arrives. A preventive intervention costs much less than repairing damage caused by undetected water infiltration, such as wood rot, mold or insulation deterioration.
Our expertise in caulking
A simple and fast process
Existing joint inspection
Our technician examines each caulking joint around your doors and windows. They identify failing areas, cracks, peeling and assess the overall sealing condition of your openings.
Old caulking removal
The old sealant is mechanically removed using specialized tools. The surface is then thoroughly cleaned to ensure optimal adhesion of the new product. This step is essential for a lasting result.
Professional sealant application
We apply a professional-grade sealant adapted to the materials and climate conditions of Quebec. The joint is smoothed for a clean and aesthetic finish. Full curing takes 24 to 48 hours.

Everything about caulking
How often should window caulking be redone?
In general, professional caulking done properly lasts between 10 and 15 years. However, we recommend an annual visual inspection, ideally in the fall. Joints exposed due south or to weather degrade more quickly and may need more frequent replacement.
How much does door and window caulking cost?
Our rates start at $8 per linear foot. The total cost depends on the number of openings to caulk, the condition of existing joints and the accessibility of the areas to treat. We offer a free on-site quote to give you an exact price tailored to your needs.
What sealant products do you use?
We exclusively use professional-grade sealants based on polyurethane or hybrid silicone, certified for northern climates. These products offer excellent elasticity to withstand freeze-thaw cycles, superior adhesion on all surface types and durability of 10 to 15 years.
Can caulking be done in winter?
Ideally, caulking is done when the temperature is above 5 degrees Celsius for optimal adhesion. However, certain professional products can be applied at lower temperatures in case of emergency. We'll advise you on the best time based on your situation.
