Keeping your home comfortable and energy-efficient starts with sealing the small gaps that let cold air in. Door caulking and weatherstripping are simple yet powerful ways to reduce drafts, improve insulation, and cut down on energy bills. In 2025, homeowners across Oshawa, Ajax, Pickering, and Toronto are paying closer attention to home sealing costs—and the good news is that door caulking remains one of the most affordable improvements you can make.
Average Door Caulking Cost in 2025
The average door caulking cost in 2025 in Ontario ranges between $100 and $250 per door when hiring a professional. Pricing varies based on factors such as the type of door, existing condition, and materials used.
- Standard exterior door sealing: $100–$150
- Front or patio doors with glass inserts: $150–$200
- Double doors or threshold repair included: $200–$250
- DIY caulking materials: $15–$40 (sealant, caulking gun, scraper)
If you add weatherstripping and draft prevention upgrades, the price can increase slightly, but you’ll gain better long-term protection against moisture and air leaks.
What Affects the Cost of Door Caulking
Several key factors determine how much you’ll pay for professional caulking services near you:
- Number of doors: Multiple doors lower the average cost per door due to efficiency.
- Sealant type: Premium silicone or hybrid caulks cost more but last longer, especially in harsh Canadian winters.
- Condition of the frame: Damaged or rotted wood requires prep work before sealing.
- Accessibility: Basement or patio doors may take more time and effort to reach.
- Labour rates: In areas like Toronto and Pickering, professional rates can be slightly higher compared to Oshawa or Ajax.
Professional vs DIY Door Sealing
While a DIY door caulking project may seem easy, improper application can lead to gaps, cracking, and early wear. Professionals ensure a consistent seal around the frame, threshold, and weatherstrip edges for long-lasting results.
- DIY: Best for small gaps or cosmetic touch-ups.
- Professional: Ideal for complete exterior door sealing, especially if you notice significant air drafts, old caulk, or visible damage.
Why Invest in Exterior Door Sealing and Draft Prevention
Proper door caulking and weatherstripping offer several benefits that make the small investment worthwhile:

- Reduces energy bills and strain on your HVAC system

How to Know It’s Time to Re-Caulk Your Doors
Watch for these common signs that your exterior doors need fresh caulking:
- You feel cold drafts around door edges
- Visible cracks or peeling in the existing sealant
- Increased humidity or water stains near the threshold
- Rising heating bills during colder months
- Dust, insects, or daylight visible through small gaps
