Optimum Home Protection With A Garage Door Threshold

A garage door threshold offers necessary home protection. To prevent rainwater from entering your space, a garage door seal will help. When your garage experiences water damage, it can be severe.

Garage door seals help keep your home protected during heavy rainstorms. If you live in an area where it rains often, chances are your garage door has a threshold. However, if you’re building a new home, you’ll need to install an excellent seal to protect your new garage from black rain damage, for example.

Garage door threshold seals protect your garage space from rainwater, leaves, and sand. The rubber seal reduces rust, which can harm your cars, tools, and appliances. Additionally, garage door weatherproof seals also protect against cold air, drafts, and snow.

Do Garage Door Threshold Seals Work?
Do Garage Door Thresholds Work?View in gallery

In modern homes, garage doors serve two purposes: 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 door seals are necessary. You also want to keep your garage clean after the door closes.

If your garage door is not insulated or if the insulation has deteriorated, your threshold will be limited. Garage door threshold seals do not provide an airtight seal, and that’s okay. A gap is kept open to prevent the door from rubbing against the floor. A threshold contributes to the closing of that gap.

How to Install Garage Door Threshold In 5 Easy Steps

Installing a garage door threshold is easy and doesn’t require that many tools compared to other projects that people do around the house. Instructions vary depending on the brand. However, we’re going to provide 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 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 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.
