The Best Garage Door Thresholds To Keep Leaves & Bugs Out (And Where to Buy Them)

Kenneth Wilson

No matter what you keep in your garage, the last thing you want is for water, pests, leaves, and dirt to enter the room regularly. Not only will they potentially ruin anything that’s stored inside, but you will also have to spend a considerable amount of time cleaning up.

The great news is that you can install a garage door threshold underneath your door to protect the inside of your garage from outside debris and critters.

Below, we introduce five of the best garage door thresholds on the market (and where to buy them) and explain why adding this simple strip to your home is a smart move.

Why Do I Need a Garage Door Threshold?

The space that exists underneath a closed garage door is sufficient for leaves, dirt, and bugs to enter and make a mess in your garage. Even attached garage doors leave enough of a gap to be exploited by pests, but fortunately, there’s a simple enough solution: garage door thresholds.

Made from various materials, garage door thresholds essentially seal your garage, preventing any unwelcome pests, dirt, or debris from entering your home. 

What Should I Look for in a Garage Door Threshold?

When looking for a suitable garage door threshold, the most important consideration is how good it is at preventing leaves, bugs, and dirt from entering inside. You should also consider the protection the sealant offers regarding water damage, as you don’t want your garage to flood during or after a heavy downfall.

Your chosen threshold also needs to be resilient and durable, as you don’t want it to become damaged after a short period of time.

Let’s look at some of the factors you need to consider before ordering a garage door threshold:

  • Height & Length - You need to begin by measuring the distance between your closed garage door and the floor. Garage door thresholds come in different sizes, so you need to look for one that adequately closes the space, providing a tight, waterproof seal for your home. Once you’ve measured the height, you will also need to measure the length of your garage door. Again, it’s a good idea to order a threshold with slightly more length than necessary, so it can be cut down and customized to suit the size of your garage door.
  • Material The best garage door thresholds are flexible and durable. They need to be strong enough to prevent water and pests from entering but flexible enough, so you don’t damage your garage door when it closes. Typically, garage door thresholds are made from vinyl, aluminum, and rubber. The aluminum provides a stiff, durable frame, while the vinyl or rubber is used to make the seal.
  • Weather Protection - Remember, the main reason for installing a garage door threshold is to protect your home from unwelcome pests, leaves, and garden debris. But an adequate sealant weatherproofs your garage, preventing cold draughts from blowing into your home, as well as its waterproof properties as mentioned above.

Now you know what to consider before ordering a garage door threshold, let’s take a look at the best thresholds on the market and where you can buy them.

Garage Door Threshold Installation Cost

As home improvement projects go, installing a garage door threshold is relatively straightforward and shouldn’t cost a great deal of money. Thresholds cost anywhere between $30 - $150, depending on the brand and length that you opt for.

You will also have to factor in the price of additional adhesive, as many products don’t come with adhesive, or provide a product that won’t necessarily get the job done. Depending on how much you need, you should be able to pick up adhesive from a local hardware store for between $10-$50

Therefore, overall, you can expect your garage door threshold installation to cost somewhere in the region of $200 or less, if you’re happy to undertake the project yourself.
