Weatherproof Sectional Garage Door Seals

Weatherproof brush seals for single and double sectional (panel lift) garage doors. Dense UV-stabilised PA6 filament in aluminium carriers closes the 5–25 mm gaps across the top and down both sides, so dust, leaves, draughts and spiders stop getting in around the door.

Pick top only, sides only, top and sides, or add the rubber bottom seal for the full perimeter. Free shipping Australia-wide, a 10-year warranty, and most customers fit theirs in one to two hours with our install video.

What is a sectional garage door brush seal?

Also called a bristle seal, brush strip, weather strip or dust seal. Same thing.

If there’s a line of dust and leaves inside your garage door every time the wind picks up, or you can see daylight down the sides when it’s closed, the gaps around the door are the problem, not the door. A sectional (panel lift) door has to clear the opening to move, so there’s normally a 5 to 25 mm gap down each side and along the lintel at the top, and nothing in the door’s own design closes it.

A brush seal does. You’ll also see it called a bristle seal, brush strip, seal strip, garage door weather strip, dust seal or draught seal (draught excluder); what hardware stores sell as a “garage door weather seal” is usually the rubber for the bottom of the door, which is a different part (see our bottom seal kits). Ours is a dense row of UV-stabilised PA6 (nylon 6) filament in a 40 mm aluminium carrier that fixes to the wall and lintel around the door. The filament brushes the panels as the door moves and springs back when it closes, so the gap is sealed and the door runs exactly as it did before.

What it fixes

The four reasons people go looking for a garage door seal.

  • Dust and leaves blowing in

    Wind pushes fine dust straight through a 10 mm gap, and dry leaves follow it. Dense filament on the top and sides cuts it dramatically. Dust in a line along the floor means the bottom seal needs attention too.

  • Draughts, and a garage that’s never comfortable

    A home gym, workshop or office in the garage is only usable if the wind isn’t coming through the walls. Sealing the perimeter stops the draughts, and the house behind the garage holds its temperature better too.

  • Spiders, cockroaches and mice

    A mouse fits through a 6 mm gap. Closing the gaps around the door, and under it with the rubber bottom seal, takes away the open invitation.

  • Wind-driven rain

    Brush on the top and sides stops rain and spray being blown in around the door. A brush isn’t a waterproof barrier, though: water under the door is the rubber bottom seal’s job.

Which weatherproof kit do I need?

Measure the opening, then pick the edges you want sealed.

  • Single door kit

    Openings up to 3 m wide and 3 m high.

    from $199

    View single kit

  • Double door kit

    Openings up to 6 m wide and 3 m high.

    from $249

    View double kit

Then choose the edges

  • Top only: brush seal along the lintel above the door.
  • Sides only: brush seal down both sides of the opening.
  • Top & sides: the full brush perimeter.
  • Top, sides & bottom: adds the 80 mm EPDM rubber bottom seal in its aluminium track.

Gaps bigger at the top than down the sides are normal: email your measurements and we’ll make up a kit with the right brush length on each edge. In a bushfire-prone area? Get the fire retardant sectional kit instead: same carriers and brush length, BAL-FZ rated flame-retardant filament.

Measuring and fitting

Two minutes to measure, an afternoon to fit.

Measure first: our sectional measuring video (1:53) shows exactly where to put the tape across the top and down both sides. Then order, or email us a photo of the door with the three measurements and we’ll confirm the kit.

Most customers fit a top-and-sides kit in one to two hours with a tape measure, pencil, hacksaw or drop saw, drill, caulking gun and a step ladder. The adhesive is in the box. When you’re done, leave the door open for an hour or two so nothing presses on the carriers while the glue sets. Rather not? In Sydney, Melbourne and Brisbane we fit it for you from $249.

Sectional seal questions

The ones we’re asked most. More on the FAQ page.

Will a brush seal stop all the dust?

It stops most of it, and it’s the difference customers notice first. No garage door is airtight: it has to move, and some dust will still come in while the door is open, or under it if the bottom seal is worn. Seal the top and sides with the brush and the bottom with the rubber seal and you’ve closed every gap the door has.

Can I seal just the sides of the garage door?

Yes. The sides-only kit is two brush seals for the gaps down each side of a sectional door, and the top-only kit is the lintel seal on its own. Most people find the top gap lets in as much as the sides, so the top and sides kit is the usual choice, but if you only have daylight down the sides, seal the sides.

Why brush on the sides and rubber on the bottom?

Rubber seals by pressing against a surface, which is perfect under the door where it sits on the floor. Run rubber along the sides of a moving door and it drags, tears and perishes. Brush filament bends with the door every time it moves and springs back, so it lasts on the edges that see movement, and dense filament stops dust and draughts nearly as well as a solid seal.

Will the brush rub on the door and make it hard to open?

No. Fitted to the right gap, the filament just brushes the face of the door: it bends out of the way as the door moves and springs back when it’s closed. The carriers hold the brush at 55 degrees so the door can’t catch it, and your opener won’t notice it’s there.

Will it fit my brand of sectional or panel lift door?

Almost certainly. The seals mount on the lintel and jambs around the door, not on the door, so the brand doesn’t matter. What matters is the gap: 5–25 mm at the top and sides, up to 35 mm under the door, and a door no more than 3 m high. We’ve fitted them to B&D, Steel-Line, Gliderol, Centurion, Taurean and Danmar doors. The one exception is a tilt door, which we don’t recommend our kits for.

Can I use it to replace a worn garage door seal?

Yes. Most sectional doors have never had side and top seals, so ours is usually the first, but if yours has an old brush seal, rubber flap or foam strip that has gone hard, torn or fallen off, pull it off, take the old adhesive or fixings with it and give the surface a clean, then fit our carriers to the same lintel and jambs. Nothing from the old seal is reused, so it doesn’t matter what brand it was. The seal that does wear out on most doors is the rubber under the door; that replacement is the bottom seal kit.

How long will it last?

We warrant the seals for 10 years, and we’ve been fitting them since 2017 without a warranty claim. PA6 filament holds its shape and springs back for years where cheaper polypropylene goes limp and chalks in the sun. The bottom rubber is the only part that wears, because it sits on the floor, and when it does you slide a new length into the track rather than replacing the lot.
