Overhead Door & Dock Weatherstripping — Stop Energy Loss at Every Gap
Weatherstripping is the most overlooked source of energy loss in commercial facilities — worn seals around overhead doors and dock openings let conditioned air escape and outside air in 24 hours a day. Wilcox supplies and installs commercial-grade weatherstripping and perimeter seals for overhead doors and dock openings across Canada.
Seal It Right. Stop Paying to Heat the Outside.
Wilcox technicians assess your existing overhead door and dock perimeter seals during service visits and identify gaps that are costing you money. We supply and install commercial-grade bottom seals, perimeter weatherstripping, and threshold seals for all door types and sizes. Fast turnaround — weatherstripping replacement is one of the highest-ROI maintenance activities on any dock.

Overhead Door Weatherstripping
We offer custom-cut, industrial-grade weatherstrip kits for all types of overhead doors:
Bottom Seals
Rubber or vinyl seals that compress along the bottom of the door to seal uneven floors
Side Seals
Brush or bulb-style seals that run vertically along the tracks to prevent air infiltration
Top Seals
Flexible header seals to close the gap between the door and lintel
Retainers
Aluminum or steel holders for securing bottom seals to sectional doors
Our weatherstripping is compatible with all major commercial door brands and can be installed as part of a preventative maintenance plan.

Frequently Asked Questions
Dock seals compress directly against trailer sides and top — best for consistent trailer sizes. Dock shelters use a frame with flexible curtains that wrap around varying trailer dimensions — better for mixed trailer fleets or high-wind loading environments.
With proper maintenance, 5–10 years. Face fabric and foam compression are the primary wear items. Annual inspection catches tears and foam set before they lead to energy loss or weather infiltration.
Yes — dock seals surface-mount to the dock face and can be fitted to most existing openings. Wilcox provides complete measurement, supply, and installation with no major structural work required.
Inflatable dock seals provide the tightest seal for refrigerated and controlled-atmosphere operations. They expand to fill irregular gaps between trailer and dock face, minimizing thermal transfer.
Annual inspection and face fabric replacement as needed. Foam-core seals should be checked for compression set — permanently compressed foam loses sealing performance. Our PM programs include dock seal inspection as part of full dock assessments.
