Exterior Caulking importance

Exterior caulking around windows in Toronto is extremely important due to the city’s climate and building standards. Here’s why:

1. Protection from Moisture

Toronto experiences heavy rain, snow, and ice. Proper caulking seals gaps and prevents water from leaking into walls, which can lead to mold, rot, and structural damage.

2. Energy Efficiency

Caulking keeps cold drafts out in winter and cool air in during summer, reducing energy bills and improving indoor comfort.

3. Pest Prevention

Gaps around windows can allow insects and rodents to enter. Caulking blocks these potential entry points.

4. Building Code Compliance

For new builds and renovations, properly sealed windows are often required to meet energy and waterproofing codes.

5. Aesthetics & Property Value

Fresh, neat caulking improves curb appeal and shows good maintenance—important for property resale.
