Garage Door Seal
Find your size
Measure the width of your garage door opening and enter it below. We'll pick the right length for you.
The XSEAL Heavy Duty Garage Door Threshold Seal closes the gap between your garage door and the floor, keeping out rainwater, leaves, mud, rodents and cold draughts. It bonds straight to your garage floor and your door closes down onto it, creating a watertight seal along the full width of the opening.
Whether your garage protects a car, tools, a home gym or a workshop, XSEAL keeps the weather on the outside.
Why choose XSEAL
- Stops water, debris and pests: a raised threshold blocks rainwater, leaves, mud and rodents from getting under the door.
- Cuts draughts: sealing the gap reduces cold air coming in and heat escaping, so your garage stays more comfortable all year.
- Built for uneven floors: the flexible rubber follows the contours of the floor, as most garage floors aren't perfectly flat.
- Drive-over strength: heavy duty 80mm wide by 18mm high profile, designed for vehicles to drive over it.
- Lasts outdoors: UV stable, odour free, and stays flexible even when it's in regular contact with water.
- Ribbed underside: grooves of varying width and depth on the base give the adhesive more to grip for a strong, permanent bond.
- Trip warning line: a bright yellow line runs along the full length so the threshold is easy to see.
- Adhesive included: every kit comes with hybrid adhesive and sealant, so you have everything you need to fit it.
Choosing your length
Measure the full width of your garage door opening and round up to the next size. Allow about 4cm extra on each side to cut in around the door frame, then cut the seal to length with a hacksaw. No special tools needed. Kits up to 14ft include 1 tube of adhesive. Kits from 15ft and above include 2 tubes.
Suitable for manual and automatic doors, including up and over, sectional, roller shutter and side hinged garage doors.

Compatibility
Fits every garage door.
Whatever door you have, it closes down onto XSEAL. Manual or automatic, the raised threshold seals the gap underneath.
The door swings down and comes to rest on the raised threshold, closing the gap along its full width.
The panels roll down the track and land on the seal, so rain and draughts can't creep underneath.
The curtain unrolls straight down onto the threshold, sealing uneven floors a bottom rubber alone can't.
The doors swing shut against the threshold, which forms a water barrier right across the opening.

-
Make Markings For Sealant
Close the door and press the seal up against it. Check the door still latches and locks. When you're happy with the placement of your seal, use a marker pen to outline the seal.
Tip: Create markings 1cm inside the main markings for the sealant
-
Apply The Adhesive

-
Place & Press Seal Into Place
Press the seal down working from one end, cleaning up any sealant squeeze-out as you go. If any edge lifts, weight it down with something heavy while the adhesive cures. Allow 24 hours to cure before driving over the seal.
Tip: Run adhesive sealant around the Seal and the door frame to prevent water ingress at the edges.

Contact us →What size do I need?
Measure the full width of your garage door opening and round up to the next kit size. Allow about 4cm extra on each side so the seal can be cut in neatly around the door frame. Kits run from 7ft to 30ft.
Will it fit my garage door?
It suits most manual and automatic garage doors, including up and over, sectional, roller shutter and side hinged. Your door simply closes down onto the raised threshold.
Can I drive over it?
Yes. The heavy duty 80mm wide by 18mm high profile is designed for vehicles to drive over. Leave the adhesive 24 hours to cure before you drive over it for the first time.
Is the adhesive included?
Yes, every kit comes with hybrid adhesive and sealant. Kits up to 14ft include 1 tube and kits from 15ft include 2 tubes.
What tools will I need?
A hacksaw to cut the seal to length, a caulking gun for the adhesive and a wire brush to prepare the floor. A junior hacksaw is handy for notching the ends around the door frame.
Where exactly should I fit it?
Directly behind or under your closed garage door, so the door rests on the threshold. The floor needs to be clean, dry and free of oil before you bond it down.
Does it work on uneven floors?
Yes. Most garage floors aren't perfectly flat, so the flexible rubber is made to follow the contours of the floor.
Can I fit it in cold weather?
Apply the adhesive when it's between 5°C and 40°C. The seal itself handles −40°C to +100°C, and the adhesive is resistant from −30°C to +95°C once cured.
What does it keep out?
Rainwater, leaves, mud, rodents and cold draughts. Sealing the gap also helps stop heat escaping, so the garage stays more comfortable all year.
