A fully sealed garage door keeps Calgary winters where they belong — outside. The combination of bottom seal, side seals and top seal creates a complete perimeter barrier when the door is closed. When any of these seals fails, cold air infiltrates the garage, moisture gets in, and insects and rodents find their way inside. Calgary’s freeze-thaw climate degrades all rubber seals faster than milder climates, making regular seal inspection particularly important here.
Bottom Seal
The bottom seal is the most important and most commonly replaced seal. It sits in a retainer channel along the bottom edge of the door and makes contact with the concrete floor when closed. In Calgary, T-style rubber bottom seals work best because they conform to uneven concrete surfaces better than bulb seals. Standard bottom seals last 3–5 years in Calgary. Signs of failure: visible daylight under the door, insects getting in, blowing snow on the garage floor, or the door freezing to the concrete.
Side and Top Weatherstripping
The side and top weatherstripping is mounted to the door frame and creates a seal against the door panel when it is closed. This rubber or vinyl strips compress against the door surface. Over time they harden, shrink or tear, leaving gaps around the perimeter. Calgary’s temperature cycling is particularly hard on the compression set of these seals — they can work fine in September and then be found brittle and gap-ridden by March. If you can see light around the sides or top of your closed door, the weatherstripping needs replacement.
Cost and Service
Bottom seal replacement costs $140–$240 + GST. Side and top weatherstripping replacement costs $120–$200 + GST. Both can be done at the same visit.

Frequently Asked Questions
How long do garage door seals last in Calgary?
Bottom seals typically last 3–5 years in Calgary. Side and top weatherstripping lasts 5–8 years. Calgary's freeze-thaw climate causes rubber to harden and crack faster than in milder cities.
What type of bottom seal is best for Calgary?
T-style rubber bottom seals rated for -40°C work best on Calgary concrete floors. They conform to surface irregularities better than bulb seals and maintain flexibility in extreme cold.
How do I know if my garage door side seals need replacing?
If you can see light around the sides or top of the closed door, or if you feel cold air coming through the sides when the door is closed, the side and top weatherstripping needs replacement.
How much does garage door seal replacement cost in Calgary?
Bottom seal: $140–$240 + GST. Side and top weatherstripping: $120–$200 + GST. Both can be done in one visit by Super G&R Garage Door Repairs with cold-rated materials and a 1-year warranty.
