Garage Door Bottom Seal & Weatherstripping Replacement Calgary
Cold air, wind, moisture or pests getting into your garage? Failed seals are the most common cause — and the most affordable fix. From $140–$240 + GST.
Why Garage Door Seals Fail Faster in Calgary
Calgary’s climate is uniquely hard on rubber and foam sealing products. The combination of ‑30°C winters, intense UV in summer and constant freeze-thaw cycles causes standard seals to crack, stiffen and shrink much faster than in milder climates. Most garage door seals in Calgary need replacement every 3–5 years.
A failed bottom seal also creates a dangerous situation in winter: the seal freezes to the concrete and can cause the opener to strip its gears trying to pull the door open. Super G&R replaces bottom seals before this happens.
Bottom Seal vs Weatherstripping — What’s the Difference?
Bottom seal runs across the bottom edge of the door and creates the seal between the door and the concrete floor. It catches dirt, moisture, pests and cold air at ground level.
Weatherstripping (also called perimeter seal) runs up both sides and across the top of the door opening. It seals the gap between the door and the door frame. When weatherstripping fails, you can see light around the door perimeter.
Signs Your Seals Need Replacing
- Cold drafts in the garage even with the door closed
- Light visible around the perimeter of the door
- Water or snow blowing under the door in winter
- Insects or mice entering through the door gap
- Bottom seal visibly cracked, torn, stiff or missing sections
- Your heating costs have increased noticeably
- Seal is more than 3–5 years old
Frequently Asked Questions
How much does bottom seal replacement cost in Calgary?
Super G&R charges $140–$240 + GST for bottom seal replacement, including the seal, retainer strip if needed, and a 1-year warranty.
Can a failed bottom seal damage my garage door opener?
Yes. In Calgary winters, a failed bottom seal can freeze to the concrete. When the opener tries to open the door, it pulls against the frozen seal and can strip opener gears or snap a cable. Replace worn seals before winter.
How long does weatherstripping replacement take?
Bottom seal replacement takes 30–60 minutes. Full perimeter weatherstripping (sides and top) takes 60–90 minutes. Most jobs are done in a single visit with parts on the truck.
What type of bottom seal do you install for Calgary winters?
We install T-style rubber bottom seals rated for temperatures down to -40°C. Standard T-seals are the most effective type for Calgary concrete floors and perform better in freeze-thaw conditions than cheaper bulb seals.
