Garage door weather seal and bottom rubber replacement in Ottawa

Why is there a gap or light under my garage door?

A gap means the bottom seal has cracked, hardened, torn, or pulled out of its retainer, or the floor is uneven. Cold air, snow, leaves, and mice get in. A fresh cold-rated rubber seal closes the gap.

Worn seals are one of the most common calls in our full-service garage door repair in Ottawa. We carry bottom rubber, side and top weatherstripping, and threshold strips on the truck, so we measure, cut, and install in one visit. Call (613) 255-1968 and stop the cold air before the next freeze.

What is the rubber strip at the bottom of a garage door called?

It is the bottom seal, also called the astragal or bottom rubber. It slides into a T-style or bead-style aluminum retainer on the bottom of the door and compresses against the floor to block water, drafts, and pests.

Bottom rubber (astragal) seal

The bottom rubber is the wide strip that compresses against the floor as the door closes. It slides into a T-style or bead-style aluminum retainer on the bottom panel. When it cracks or tears, water and drafts pour in. We match the right profile to your retainer, whether the door is a Garaga, Clopay, or Steel-Craft.

Side and top weatherstripping

Side and top weatherstripping is the flexible vinyl or rubber flap nailed to the wood stop around the door frame. It seals the gap between the door and the jamb. Sun and cold make it shrink and curl, which lets wind whistle through the edges even when the bottom seal is fine.

Threshold seal for an uneven floor

A threshold seal is a rubber strip bonded to the floor itself, raised so the door seals against it. It is the best fix when the slab slopes or has dips that the bottom rubber cannot bridge. It also stops meltwater from running into the garage and freezing the door shut.

Will a new weather seal stop my garage door freezing to the ground?

It helps a lot. A flexible cold-rated EPDM seal sheds water instead of holding it against the floor where it freezes into an ice bond. Pairing the seal with a threshold strip keeps meltwater out entirely.

Cracked, hardened, or torn bottom rubber

Cheap PVC rubber goes brittle in our winters. It hardens, splits along the crease, and stops springing back into shape, so it no longer touches the floor across the full width. We replace it with cold-rated EPDM or TPE rubber that stays flexible to minus 40, the kind Garaga and Steel-Craft spec for this climate.

A door that freezes to the ground

When meltwater pools under a worn seal and refreezes, it bonds the rubber to the slab in an ice bond. Forcing the door then rips the seal out of the retainer. A flexible seal plus a threshold strip sheds the water instead. For the full method, read our guide on what to do when a garage door is frozen to the ground.

How much does garage door weather seal replacement cost in Ottawa?

Bottom rubber replacement on a single door runs about $90 to $180 installed. Adding side and top weatherstripping or a threshold seal increases that with the door size. The service call is free when the work totals over $250.

We quote the price before we start, never after, and there are no overtime fees. If your rollers are also dry or worn, bundling the seal with a garage door roller replacement and tune-up saves a second trip and gets the whole door running quiet and tight for winter.

Why does a good weather seal matter in Ottawa and Gatineau winters?

A worn seal turns an attached garage into an open vent. With Ottawa lows near minus 25, cold air pours under the door, chills the room above, and drives up your heating bill. A tight seal keeps that heat and energy where it belongs.

Beyond comfort and energy loss, the seal blocks the snow, road salt, leaves, and mice that ride a draft into the garage. It protects stored tools and a parked car from the worst of the cold. A fresh seal is the cheapest weatherproofing upgrade your garage can get.

When is the best time to replace your weather seal?

The best time is fall, before the first hard freeze. New rubber seats and compresses best in mild weather, and you avoid fighting a door that is already iced to the slab. Booking in October or November beats the December rush.

A bottom rubber swap takes about 30 to 45 minutes on site. Adding side and top weatherstripping or a threshold seal brings most jobs to under 90 minutes, so it is almost always a single same-day visit. Watch for these signs that yours is due:

• You feel a cold draft or see daylight along the bottom of the closed door.
• The bottom rubber is cracked, hardened, flattened, or hanging loose.
• Snow, leaves, or water blow in under the door after a storm.
• The door stuck or froze to the floor last winter.

Is the weather seal replacement guaranteed?

Every weather seal we install is backed by our 90-day Done-Right Guarantee. If the new rubber pulls out, gaps, or fails to seal, we come back and make it right at no charge. The work is done by a factory-trained technician.

HUSH is owner-operated by Omar, a factory-trained technician, and we are fully licensed and insured (WSIB clearance #7421809, Ontario business #76481 2935 RT0001). You get the same careful work whether it is a $120 seal swap or a full door, with an upfront written price either way.

Where do you replace weather seals across Ottawa and Gatineau?

We come to you across the region, from Kanata to Orleans and across the river to Gatineau and Aylmer. Exposed rural and acreage doors take the brunt of wind and drifting snow, so we keep extra cold-rated rubber on the truck for them.

See our Ottawa and Gatineau service areas for the full map. Exposed rural properties in Carp and Greely take the worst of the wind-driven snow, which finds every worn seal, so we stock extra cold-rated rubber for them. If a worn seal is letting your door fail to close fully, tell us your suburb when you call and we will schedule the closest opening.
