Commercial Garage Door Weather Seal Replacement — Vancouver

A failing weather seal on a commercial door is not just about draughts. It lets in rain, rodents, and insects. On a refrigerated loading dock or cold storage facility, it is a direct energy cost — and on a food-safe facility, a pest-entry point is a compliance issue. We replace bottom seals, side seals, and top seals on commercial overhead doors across Greater Vancouver. Call 604-206-5727.

Types of Commercial Door Seals

Bottom seals sit in a retainer channel across the bottom of the door’s lowest panel and compress against the floor when the door closes. The common type is a rubber or vinyl T-bar seal or a brush seal. T-bar seals on commercial doors take vehicle traffic and wear out faster than side or top seals. Brush seals last longer under vehicle contact but are less effective as a thermal barrier.

Side seals — also called stop moulding or jamb seals — compress against the door frame stop on each side. They are typically vinyl or rubber extruded sections fastened to the door jamb. Top seals sit in a header retainer above the top panel and seal the gap at the top of the door. All three degrade over time, particularly in Vancouver’s wet climate, and typically need replacement every 5 to 8 years on an active commercial door.

Cold Storage and Refrigerated Dock Seals

Cold storage doors and refrigerated dock doors need seals that maintain flexibility down to -30°C. Standard rubber seals stiffen in cold and no longer compress properly. Low-temperature seals use specialty compounds that stay pliable in cold — critical for a seal that is supposed to close a gap between the door and an unheated concrete floor in winter.

Dock Shelter and Dock Seal Pads

Dock shelters and dock seal pads are the foam or fabric structures around a dock opening that seal the gap between the building and a backed-in trailer. They are separate from the door seals and require their own service interval. Torn dock shelter pads are a common source of energy loss in loading dock facilities.

Frequently Asked Questions

How do I know if my commercial door weather seal needs replacing?

Look for daylight visible around the door perimeter when it is closed. Run your hand along the seal edge with the door down — you should not feel airflow. Cracked, split, or deformed seal material that no longer bounces back when compressed is past its useful life.

How often should commercial door weather seals be replaced?

Bottom seals on active commercial doors that see vehicle traffic over the threshold typically last 3 to 5 years. Side and top seals last longer — usually 5 to 8 years in Vancouver’s climate. Cold storage seals should be inspected annually; a compromised seal is a measurable energy cost in a refrigerated environment.

Can weather seal replacement be done without taking the door down?

Yes. Bottom seal replacement is done with the door in the closed position — the retainer channel is unbolted, the old seal removed, and the new seal inserted and secured. Side and top seals are replaced with the door closed or open depending on the configuration. There is no need to disassemble the door.

Do you replace dock shelter seals as well as door seals?

Yes. We replace dock shelter foam pads and fabric sections as well as standard door perimeter seals. If you are getting a door service and you notice the dock shelter is torn or compressed flat, ask us to look at it on the same visit.
