How to Weather Seal Garage Doors

By Stormstop / 18th September 2024

Now is the perfect time to give your garage space some TLC and ensure it is all in working order. We recently shared some general garage maintenance tips but we’re going to deep-dive into everything weatherstripping and talk you through how to weather seal your garage door.

Why Weather Seal a Garage Door?

Your garage is often an extension of your home and should be offered the same protection as any other entryway into your home. By weatherproofing your garage door, you’ll be preventing external elements such as draughts, rainwater and rodents from entering into your garage and as an extension, your home. Garages are often neglected insulation-wise as an outdoor space but could be costing you money on heating bills as well as suffering from mould and damage caused by damp conditions. Installing a waterproof garage door seal is an ideal way to avoid these issues.

What is Weatherstripping?

Weatherstripping is the rubber seal that fits around your garage door in order to protect it from the elements. Weatherstripping can help to keep rainwater and draughts out of your garage space year-round. There are some key areas to focus on when weatherproofing your garage door. These include the bottom edge where a threshold seal can help seal up the gap, the sides where weatherstripping is perfect and the top where weatherstripping can also play a part in weatherproofing your garage door.

 

 

How to Weather Seal a Garage Door

Before you get started, here is a list of the supplies you’ll need to effectively install your garage door weather seal.

  1. Stormstop garage door weather seal​s 
  2. Damp cloth (for cleaning the garage door and seals)
  3. Self-tapping screws (optional for additional support when fitting the seal)
  4. Measuring tape
  5. Scissors or utility knife (for cutting the weather seal to size)
  6. Screwdriver (if using self-tapping screws)

 

There are a few key stages to waterproofing garage doors and it is important to follow the proper steps to ensure your garage door is protected from weather year-round. 

 

Step One: Inspect Existing Door Seals

No matter what age your garage door is, when weather sealing garage doors, the first step should always be to check existing seals on the door. Use a damp cloth to gently clean your garage door and existing garage door weatherproofing as this will help you to better evaluate their condition.

Once they are free from dirt and debris, inspect the weatherseals for cracks, tears or damage, if any damage is present, replacing your garage door weatherstripping is the best step.

 

Step Two: Choose the Correct Garage Door Weatherproofing

Your new weatherstripping should match the size and style of your existing garage seal. Aim to choose a high-quality long-lasting garage weatherstripping such as Stormstop’s garage door multiseals to ensure your garage door weatherstripping lasts and won't need replacing again any time soon.

Step Three: Prepare Your Garage Door

Whilst you might have given your garage doors a quick wipe in the first step, garage door weather stripping requires a completely clean and clear surface in order to be effective. Remove the old weather stripping and thoroughly clean the area you will be applying your new garage door seal to ensure it is completely dry before starting the application.

 

Step Four: Measure Twice, Cut Once

You’ll now need to cut your garage weather seal to size using the measurements from your garage door. You’ll be able to easily cut your new seal yourself but it’s important to cut it to the right size to avoid gaps around your garage door that could let in rainwater or draughts.

 

Step Five: Fitting Garage Door Weather Stripping

Installing weatherstripping on your garage door is simple. Once you’re ready, simply remove the backing from your new seal. Next, press the weatherstripping against the side of the garage door, starting with the bottom of the door, aligning the smaller edge with the outside as you go until you have covered the full edge and sides of the door.

 

If your weather seal looks like it needs some extra support, gently tap in the self-tapping screws that will be included with your Stormstop garage weather seal.

 

Step Six: Test Your Garage Door

Once your garage door is fully weatherproofed and your new seal is fully adhered to your door, try using your garage door as usual to check that it isn’t obstructed by the new weatherstripping and functions as it should. Ensure there are no gaps where you have applied your new seal. You can check for gaps in your garage door seal by checking for light gaps or running your hand along the edges of the door to feel for draughts.
