Small Gaps That Let Big Problems In
The rubber or vinyl seal along the bottom of a door, plus the stripping around the sides and top, close the gap between a moving door and a fixed frame. Sun and humidity gradually stiffen and crack them.
Once a seal has shrunk or split, you may notice dust blowing across the floor, rainwater creeping in or insects finding a way through. Replacing it is a tidy job that improves the garage and the first impression the door gives.
When a Seal Has Had Its Day
Daylight under the door
A visible line of light along the floor when the door is closed shows the bottom seal no longer meets the slab.
Flattened or brittle rubber
Seals that have gone hard, cracked or lost their springiness cannot compress against the floor as designed.
Dust, leaves or insects inside
Debris collecting along the door line, or small pests appearing indoors, often trace back to a failing seal.
Replacing the Seals
- i
Measure and match
Door width, track type and seal style are checked so the replacement is compatible with the retainer on your door.
- ii
Remove the worn seal
The worn strip slides out of its channel, then the retainer behind it is wiped down and checked for bends or rust.
- iii
Fit new bottom and side seals
A fresh seal is cut to length and seated evenly, while side and top stops are adjusted to touch the door lightly.
- iv
Check the closed door
We close the door, look for any remaining gaps and confirm that the new seal does not make the opener work harder.
Weather Seal Questions
Is the seal the same on every door?
No. Seals come in several profiles, such as T-shaped, bulb and J-style, and each fits a particular retainer. We match yours so the new strip sits snugly rather than loose or crooked, and we check the retainer itself for damage first.
Will new seals reduce noise?
They can soften the thud of the door meeting the floor and cut down on wind whistling at the edges. Do not expect a new seal to quiet a rattling track, though, since that noise comes from the rollers and hardware instead.
Can uneven floors be accommodated?
A slightly uneven slab can usually be handled with a seal that flexes to follow it. Larger dips or a sloping apron may call for a threshold strip, which we discuss during the visit so you know what to expect.
Noticing Gaps Around the Door?
Tell us where light or debris is getting in, along the floor or around the edges. We will explain which seal style probably fits and what replacing it involves.
