Keep Out The Water With A Garage Door Threshold

During inclement weather, there’s nothing worse than rainwater seeping into your garage and damaging all of the items that you’ve got in there. If that has happened to you before, it’s time to get a garage door threshold.

Garage Door Threshold

Not only will a garage door threshold prevent rainwater, leaves, dust or sand from entering your garage, but it’ll also minimise the chances of rusting occurring – which can be detrimental to the vehicles, tools and appliances that you’ve got stored inside your garage.

Additionally, a garage door weather seal will also protect against cold air, drafts and snow. Garage door thresholds are also great to have if the floor of your garage is currently not level or your gasket strip at the bottom of the door has become worn. 

Do Garage Door Thresholds Work?

Do Garage Door Thresholds Work?View in gallery

In contemporary homes, garage doors have a dual purpose: they keep the contents of the garage secure and serve as protective shields for the house. Every home requires security and storage space, which is why garage doors are so necessary. Many homeowners have realized, however, that their garage doors are incapable of performing these two jobs.

For example, their doors don’t trap heat inside the garage, which results in higher energy expenses. Additionally, their garage doors are ineffective at keeping out moisture, snow, and leaves. This is when garage door thresholds enter the picture. However, do garage door thresholds function properly? 

Thresholds are a garage door component. However, how it operates is very dependent on the garage door. Therefore, if your garage door is not insulated or if the insulation has deteriorated due to age or use, the threshold has limitations.

Thus, the issue arises: why apply a threshold at all? To begin, a garage door does not automatically form an airtight seal. A gap is always kept open to prevent the door from rubbing against the floor when it is opened or closed. A threshold contributes to the closing of that gap.

Who Makes the Best Garage Door Threshold Seal?

Tsunami Seal 53050

The Tsunami door seal attaches to the garage floor, giving an ideal seal between the floor and the door. This product forms a tight seal around your garage door, preventing leaves, snow, and water from being blown beneath it by the wind. 

Additionally, if your driveway is slanted or your garage floor is not even and water is infiltrated underneath the door, this seal will create a 1/2-inch height barrier on the garage floor. Additionally, it will keep out unwelcome critters.

Garage door insulation is an excellent way to maintain a pleasant temperature in your garage space, allowing you to work, play, or simply hang out without freezing. This layer of insulation not only helps prevent heat loss, but also keeps cold air at a distance, keeping your car safe from the potential threats of cold winter air.

When working hand-in-hand with thresholds, these products do a great job in making sure warm air stays in and cold air stays out of the garage, so let’s have a look at the top three insulation kits that might be worthy of your garage door.

Additionally, this kit includes a utility knife for cutting the insulation to size, a squeegee to help you prepare the door for installation, and double-sided tape for attaching the insulation.

How to Install Garage Door Threshold

Installing a garage door threshold is very easy and doesn’t require that many tools compared to other projects that people usually do around the house. Note that instructions may vary depending on the brand you’re looking to install, but we’re going to provide some general guidelines on how it’s done.

What you’ll need:

  • Pencil
  • Utility knife
  • Tape measure
  • Threshold
  • Rubbing alcohol
  • Adhesive 

Step One

Thoroughly clean the area where the threshold will be installed. You can use rubbing alcohol to remove everything from oil to mud.

Step Two

Position the threshold in the spot where you’re going to install it. Using a pencil, draw the outline of the threshold and then remove it to clear the working area.

Step Three

Apply the adhesive on the floor, staying within the outline you previously marked. It’s best to apply it in three strips of ¼ inches each. One strip needs to be in the center, and the other two, on the edges of the mark.

Step Four

Position the threshold carefully on top of the adhesive and firmly press it down when it’s in the correct place.

Step Five

Close the garage door and leave it like that for 24 hours, to make sure enough pressure is applied on the threshold so that it properly sticks.


How Do I Know the Correct Height for My Garage Door Threshold? 

To know the correct height, you have to measure the gap between the bottom of your garage door and the floor in a few places and take note of the largest measurement. Since it’s highly unlikely that your floor’s level, it’s a must to measure the gap at least three to four times to figure out where the most significant gap is. 

Once you’ve got the biggest measurement, another thing to consider is the level of protection that you require. If you tend to get storms in your area, you’d want to select a higher seal to help with keeping out water. 

How Do I Know the Correct Length for My Garage Door Threshold? 

To figure out the right length for your garage door threshold, you’d want to measure the width of the opening. If you need to, you can also easily cut the threshold to the size you require with either a pair of scissors or a hacksaw. 

What are the Different Garage Door Threshold Materials? 

With garage door thresholds, they typically come in two different materials – aluminum and vinyl. Aluminum thresholds are great if you’ve got a garage that’s storing large equipment as they’re incredibly durable. They’ll also minimize airflow and prevent any water and debris from entering your garage. 

Vinyl garage door thresholds, on the other hand, are a popular choice if you’re concerned about aesthetics. These thresholds come in a variety of colours with some even having a wood grain-like aesthetic. While they are durable, they can crack when exposed to high temperatures or weight; hence they’re not a great option if you’re storing heavy equipment in your garage. 

Bottom Line 

We hope that this article has helped you learn more about garage door thresholds and you were able to choose one that best suits your needs. Garage door thresholds are great to have if you’re looking to protect the items that you have stored in your garage. When it comes to selecting your garage door threshold, remember to check that it’s of the correct height and length, and comes in a material that suits your needs.
