Using the local average as a guide, our pricing starts at just:
- $3.50 – $8.50 per linear foot, depending on window size, condition, and accessibility

What is Window Caulking and Why is It Important?
Window caulking involves sealing the joints and gaps around your windows with a waterproof material to prevent air leaks, water infiltration, and heat loss. Over time, caulking deteriorates due to exposure to sun, wind, and seasonal temperature changes when winter and summer extremes are common.
Here are a few benefits of exterior window caulking:
- Improves insulation and energy efficiency
- Prevents mold, mildew, and water damage
- Increases window lifespan
- Enhances indoor comfort year-round
Professional vs. DIY Caulking
While some homeowners opt to purchase a few tubes of caulk and seal windows themselves, professional window caulking services come with several advantages:
- Uniform, clean application
- Access to premium, long-lasting sealants
- Proper removal of deteriorated caulk
- Long-term durability and energy savings
When Should You Re-Caulk Your Windows?
Toronto’s climate plays a big role in caulking wear and tear. We recommend checking your caulking every 2–3 years and re-caulking every 5 years or sooner if you notice:
- Visible cracks or gaps
- Drafts near your windows
- Moisture buildup or condensation
- Peeling or deteriorated sealant
Spring and fall are ideal times to schedule your window caulking in Toronto, as temperatures are moderate and humidity is lower.
