Garage Door Weatherstripping Installation
Detailed Description
An Unsealed Garage Door in Your Toronto & GTA Home Is an Open Invitation for Cold Air, Water, and Pests
Garage doors are the largest operable opening in most Toronto & GTA homes — and often the least well-sealed. The bottom seal compresses and cracks. The side and top seals shrink and separate from the door jamb. The result is a garage that drops to outdoor temperature in winter (costing more to keep the adjacent living space warm), allows blowing rain and snow under and around the door, and provides easy entry points for mice and insects seeking warm shelter in Toronto & GTA’s fall and winter. In homes where the garage shares a wall with conditioned living space, a well-sealed garage door is a direct energy efficiency improvement.
At CNG Contracting, garage door weatherstripping replacement in Toronto & GTA addresses all four sides — bottom, both sides, and top — with products rated for the temperature range and UV exposure of Toronto & GTA’s climate. Not the cheapest available product — the one that actually seals and lasts through multiple seasons.
What Garage Door Sealing Covers in Toronto & GTA
- Bottom Seal Replacement: The garage door bottom seal is the highest-wear component — dragging against the floor with every door cycle. Rubber astragal or brush seals appropriate for your Toronto & GTA home’s floor surface and door configuration.
- Side Jamb Seals: The compression seals at the door sides that prevent air and water infiltration where the door meets the vertical track framing — often failed or missing in Toronto & GTA homes with older garage doors.
- Top Seal: The seal at the top of the garage door — critical for preventing blowing rain and wind infiltration in Toronto & GTA’s weather.
- Threshold Seal: Where the garage floor isn’t perfectly level at the door line — a threshold seal at the floor accommodates irregularities that the door bottom seal alone can’t bridge.
Why Garage Weathersealing Matters in Toronto & GTA
- Properly sealed garages attached to Toronto & GTA homes reduce heating costs by reducing thermal exchange through the garage space
- Mice and other small rodents enter Toronto & GTA homes primarily through the garage — bottom seals that have failed or been compressed flat are the most common entry point
- Blowing snow in Toronto & GTA winters packs under unsealed garage doors and melts onto garage floors — promoting corrosion of stored equipment and salt spread to adjacent surfaces
- A sealed, temperate garage is safer for parked vehicles and stored equipment through Toronto & GTA’s freeze-thaw cycling

Frequently Asked — Garage Door Sealing in Toronto & GTA
How do I know if my Toronto & GTA garage door seals need replacement?
With the door closed, look for visible light around the perimeter — any light visible means air and water can get through. A piece of paper that can be pulled out from under a closed door indicates the bottom seal isn’t compressing against the floor. We check all seal points during the visit.
Can garage door seals stop mice from entering Toronto & GTA homes?
A properly sealed garage door bottom significantly reduces mouse entry at that point — mice can squeeze through gaps the thickness of a pen, and a failed astragal seal typically has gaps far larger than this. Combined with checking for other entry points, bottom seal replacement is one of the most effective first steps in mouse exclusion for Toronto & GTA homes.
How do I book garage door sealing in Toronto & GTA?

Why is a Technical Visit necessary?
Concrete garage floors are rarely perfectly level; they often shift and crack over time. Buying a standard "universal" seal from a hardware store often fails because it doesn't account for these dips. Our Garage Door Weatherstripping Installation assessment measures the gap variance across the entire width of the door to select the correct size and type of bottom rubber (bulb vs. T-style) to ensure a complete seal.
