Signs Your Bottom Seal Needs Replacement
Why Montreal Bottom Seals Fail Faster
Repeated freeze-thaw cycles crack the rubber year after year
Road salt on driveways degrades the underside of the seal
Aging OEM seals from 15+ year-old doors have simply reached end of life
Uneven concrete floor prevents proper contact and wears one side out
Rodents chew through the rubber, leaving gaps for cold air
Damaged retainer channel — no seal will fit properly until it is replaced
What to Check Before We Arrive
A bottom seal replacement is one of the highest-value winter repairs you can make in Montreal. It lowers heating costs, protects stored items from freezing, and keeps water and rodents out. Before we arrive, it helps to: 1. Measure your door's width in feet — most Montreal residential doors are 8, 9, 10, or 16 feet wide. We stock seals for all common sizes. 2. Look at the current retainer (the metal channel the seal slides into). Is it straight and solid, or bent and rusted? If the retainer is damaged, we will need to replace it too — worth knowing before we arrive. 3. Check whether the concrete floor under the door is level. If there is a slope or crack, we may recommend a thicker T-style or bubble seal for better contact. 4. Move anything inside the garage that is stored right against the door — we need clear access to lift the door and slide out the old seal. Most bottom seals are replaced in 30 to 60 minutes on-site. Retainer replacement adds 30 minutes.
Our Bottom Seal Replacement Process
Measure door width and inspect the existing retainer channel
Recommend the right seal profile (T, U, bulb, or dual-lip) based on floor condition
Remove the old seal — cut and pull it out of the retainer
Clean and lubricate the retainer channel to prevent seal binding
Install new winter-grade seal, sized precisely and locked in place
Cycle test — close the door and inspect for full contact across the entire width
