Garage Door Seals in Brisbane

Your garage door is the largest door in your home, which makes water and weatherproofing crucial. If you’re sick of mopping up water, exterminating pests, and freezing cold winds, it’s time for a better solution – it’s time for KoolDoor.

Have you noticed water, grime, or bugs in your garage? It’s likely the cause can be traced back to your door. Your garage door can take up to 50% of your Brisbane home’s street-facing space, and without adequate weatherstripping or sealing, the outside can easily get in.

At KoolDoor, we provide a range of garage door insulation systems to transform your space into, well….anything. From home offices to mancaves, kid’s rooms to pet rooms, an insulated garage enhances your lifestyle and maximises the space in your home.

Should I get an insulated garage door

What is a seal for garage doors?

They provide protection against the elements, inc. dirt, pests, rain, smoke, embers, and pollution through a tight seal that’s applied around your garage door. Every garage owner knows the feeling of ducking out to grab something from the car, only to feel the draught and wind turn your garage into a cool room. With bottom seals, and sectional top and side seals, it’s never been easier to close the gaps around your doors.

If you’ve ever wanted to make use of your garage space but felt the area wasn’t comfortable enough for you, your kids, or your pets, you can safely kiss that problem goodbye.

With them, you’re able to keep unwanted breeze, wind, and rain out, and help elevate your garage into a more usable space. When cold air and moisture are kept out, you can enjoy your garage space in a range of ways from a home gym to a kid’s playroom, a home office to a mancave (you could also use it as a garage of course).

What type of door seals are available for my garage door?

We’re proud to offer a range of garage door seals to fill the gaps around your door, whether it’s sectional or roller. Our sectional side seals and roller door side seals are made from high-quality aluminium seal carriers with a fixed, thick bristle brush behind the sides (jambs) and top (lintel) interior face of your garage.

Reducing airflow in your Brisbane garage by up to 96%, choose from standard or flame-resistant bristle brush for protection in bushfire-prone suburbs. If you require assistance with custom sizing, we’re happy to help.

PLEASE NOTE: Garage door weather seals to stop dust and heat transfer around the edges of your door are also available.

What can a KoolDoors seal keep out?

Without a seal, your garage is a warm and dry place for Brisbane’s creepy crawlies to call home. Not to mention the leaves, debris, and dust that’s brought in by the wind. And forget about enjoying your garage on a cold and rainy day, because freezing draughts and water can easily pass underneath your door.

So, what can our seals protect against? Turns out, quite a lot:

✘ Heat
✘ Rain
✘ Wind
✘ Pests

✘ Dust
✘ Leaves
✘ Bushfire embers
✘ Smoke

Quick and easy to install, KoolDoor seals are the simple solution to a complex problem. When you want to enjoy your garage space – whatever that means to you – use KoolDoor garage seals to get the job done.

Can I install a garage door seal myself?


All KoolDoor products are designed for simple DIY applications, though you can use the services of a local handyman if you’d prefer. While the exact installation steps will depend on your garage door type, size, and location, consider the following step-by-step checklist as a guide.

Step One: Clamp your door in place, or unplug the power if your door is battery/remote operated.

Step Two: Check for screws holding the current weatherstrip in place (typically one screw at either end of your door)

Step Three: Remove your old seal (pull sharply if no bottom track is present, slide out if the bottom track is present)

Step Four: Prepare your garage door for your new KoolDoor seal (remove all dirt and debris with a brush)

Step Five: Secure your new door seal (hammer into place if no bottom track is present, slide into place if the bottom track is present)

Step Six: Trim off excess seal (making sure your seal sits flush with the edge of your garage door)

Step Seven: Admire your handiwork and enjoy a drink in your insulated, weather-protected garage

Frequently Asked Questions About Garage Door Seals in Brisbane

Choosing the right material for your door seal or weatherstrip is critical. The wrong material can leave your garage without lasting protection. You don’t want to wake up to a few centimetres of water or a large ant colony that’s recently moved in, so we recommend the most durable materials – rubber, vinyl, foam. While vinyl is the most durable material, it’s not suited to all applications. For help choosing the right seal for your Brisbane home, reach out and contact a member of our team on 1300 37 38 39.

Both. Your door seals act as weather seals AND door insulation strips. Not only will you prevent rain and moisture from entering your garage, but your seals provide insulation to help regulate temperature by blocking leaks, preventing unwanted draughts, and regulating your garage’s internal temperature. From lower energy bills to a dry space on Brisbane’s (rare) rainy days, you get it all.

Consider the following tools if you plan on installing your new garage seals:

  • New KoolDoor seal
  • Measuring tape
  • Flathead and Phillips head screwdriver
  • Sweeping brush
  • Utility knife
  • A volunteer to help
  • A drink to enjoy when you’re done

This depends on the size of your garage door and the complexity of the job, as well as your experience working with door seals. However, even a DIY beginner can remove and install a new seal within a few hours.

For support with your door seal installation, check out our handy video tutorials.

Our garage seals are available in either 19mm or 25mm width, constructed on a durable aluminium carrier for lasting strength and protection. Oversize panels are available, so please get in touch if you require a custom sealing solution.
