Garage Door Sealing in Toronto & the GTA
Protect Your Garage from Drafts, Moisture, and Pests
A well-sealed garage door helps block cold air, rain, dust, and even insects from getting into your garage. At TBC Garage Doors, we offer professional garage door sealing in Toronto and the GTA to close gaps, improve insulation, and protect your home from the elements.
Whether you’ve noticed light coming in around the edges or water pooling at the threshold, we’ll fix the issue quickly and effectively.
Why Garage Door Sealing Matters
Sealing your garage door does more than just stop drafts. It also:
- Reduces energy loss
- Helps keep your garage dry and clean
- Blocks leaves, bugs, and rodents
- Prevents rust and water damage to tools or vehicles
- Improves soundproofing and comfort
What We Seal
We inspect and seal the three most common problem areas:
Bottom seal (threshold seal)
This rubber strip keeps out water, dirt, and pests where the door meets the ground. We replace worn or cracked seals with durable, weatherproof alternatives.
Side and top seals
Flexible vinyl or rubber seals along the vertical edges and top of the door prevent drafts and reduce noise.
Garage frame and trim
If your wood framing has gaps or warping, we can fill or weatherproof it to stop air leakage.
We use high-quality materials designed to handle Toronto’s changing seasons and temperatures.
