Garage Door Sealing in Toronto & GTA
Bottom, side, top and threshold seals replaced — stop drafts, snow melt and mice.
Call Us At (647) 763-7374 for your garage door repair and installation.

We diagnose the whole door, not just the loud part.
Every garage door has four seal lines: a bottom astragal, two side-jamb seals, a top header seal and (sometimes) a threshold strip glued to the slab. They all break down — UV cracks the rubber, the bottom seal flattens after a few winters, mice chew through corners. Once any of them go, you get drafts, snowmelt running into the garage, salt dust over everything and pests.
We replace whichever seal lines are gone. Bottom astragals are usually 15 minutes — door up, old seal slides out of the aluminum retainer, new one in. Side and top seals get peeled off the jamb and re-nailed with new vinyl. Threshold seals get the floor cleaned, the strip cut to length and glued down. Most full-seal jobs are under an hour.
We carry P-style and T-style bottom astragals, side-jamb vinyl in black, white, and brown, and aluminum threshold strips up to 20 feet — so you're not waiting on parts.
A proper garage door sealing visit includes:
Bottom astragal replacement (T-style or P-style)
Side-jamb and top-header vinyl seal replacement
Threshold seal install (glued and screwed to slab)
Inspection of all four seal lines before quoting
Aluminum retainer replacement when corroded
Corner mitre and overlap seal at joints
Small symptoms become expensive when the door keeps cycling.
Clean process, from first call to final balance test.
Tell the dispatcher what failed. Photos help, but they are not required.
The closest stocked van gets the ticket and you get the ETA.
Spring math, cable tension, track, opener force and safety reverse checked.
You approve the written number first. Most jobs finish the same visit.

Photos from real GTA driveways, not stock libraries.
Springs cycled past their lifespan, openers that lost a logic board after a power surge, panels punched by a bumper at 2 km/h — the work in the photo gallery is the same work the dispatcher will quote you on the phone.

"Tech rang the doorbell at the 33-minute mark on a Sunday. Both torsion springs swapped, door rebalanced, opener re-paired. Quote on the driveway, invoice matched. I'm keeping the magnet on the fridge."
"Three other companies sent me to voicemail. In-Trust picked up, explained the $29 service call, diagnosed the spring system on-site, and the invoice matched the quote. No upsell, no surprise."
"Door wouldn't latch and I had a 7am meeting. They re-aligned the sensors, snugged a loose track bolt, and were back in the van in 22 minutes. Booking them for the new install in May."
Questions customers ask before booking.
How long does a bottom seal last?+
4–7 winters in the GTA. Salt and UV are what kill them.
Threshold seal or bottom astragal — which?+
Both if the slab is uneven. The bottom seal moves with the door, the threshold seals the gap below it.
Will a threshold seal stop garage flooding?+
It stops driveway run-off and wind-driven rain. Won't stop a flooded driveway, but handles the everyday water.
Can I replace the bottom seal myself?+
Yes, if the door is balanced and the aluminum retainer is in good shape. We'd rather you call — most DIYs leave 6" of seal hanging out one end.
