A garage door seal, also known as weatherstripping or astragal, works to close all of the cracks, apertures, and gaps in a garage door. This technique works well to keep out moisture, noise, and animals like rats, and insects. You’ll put them in all the door’s edges to stop any of the aforementioned people from entering. In order to get the most out of your purchase, you must understand how to install a garage door seal. The installation procedure is not very complicated.

First, you’ll need to get the exact measurements of your door. This step requires you to have reliable snips pruning sheers, and a saw. A fitting weatherstrip assures you of enhanced effectiveness. It will also help ensure that the door remains steadfast. You’ll then clean the garage floor and the bottom part of the door. Removing debris and dirt on the surfaces ensures that the weatherstripping holds firmly and for a long time.

Cut the weatherstripping seals and attach them to the surfaces. Preferably, place your seals in a criss-cross style. The rubbery part must be under the door. Further, ensure that you let the seal dry for approximately one day. It will also help if you selected exceptional weatherstripping products. The Clopay Garage Door Rubber Bottom Weather Seal could be a wonderful choice. This item offers reliability, durability, and enhanced sturdiness. Also, it is pretty affordable.

Bottom Seal

A garage bottom seal is a strip that has to be added at the bottom of your garage door. This seal is often made from vinyl, a flexible material that readily compresses when the door closes. Its compression ensures that every gap or crack is sealed, keeping out cold breezes, dirt, and rodents.

You’ll need a simple strip-style bottom seal for your garage door. It should come with angled edges that comfortably cover the gaps and cracks on your door.

Its popularity is thanks to its ease of installation. The installation process is straightforward, taking the least time and effort. It requires you to follow these steps:

  • Get the exact measurements of the bottom part of the door
  • Cut your seals per the size measured
  • Using clips, attach the seals to the door

At the same time, double-check whether you buy the best bottom seal. If it is, it becomes easier to attain value for your money. You could consider various options in the market, yet the Colibrox bottom weather seal stands out. It is suitable for commercial, industrial, and residential use, because of its heavy-duty construction. You can also rely on it if you have a steel garage door.

Seal the Sides

Weatherstripping the sides of your garage door will help keep noise and cold breezes out, boosting your comfort. Its straightforward installation process makes it an ideal choice for any DIY enthusiast. This installation process requires you to follow these steps.

  • Make sure that you have the correct door measurements. This aspect helps get the right size of weatherstripping seals. In contrast, you could buy the entire tape and cut it to size while at home. However, this latter option could be a little wasteful.
  • Tack or adhere your weatherstripping tape to the sides of the door. Adhering comes in handier if the tape has an adhesive back.
  • Install heavy-duty staples to hold the tape firmer. You could also use small tacking nails, which help improve longevity and robustness.

Choosing top-quality weatherstripping should be your primary priority. An excellent choice should highlight robustness, value for money, premium quality, and enhanced durability. Perhaps, you should opt for the Eapele 20-ft Garage Door Threshold Seal. This item is made from rubber, meaning that it is effective, flexible, and long-lasting.

Top Seal

Sealing the top of your garage door will also help. The top seal is designed to minimize heat wastage and prevent cold breezes from getting into the garage. You can also rely on it to block noise and rodents. This seal is often placed between the door frame and the garage door, blocking every opening, gap, and crack.

Installing a top seal is relatively straightforward, and it assures you of instant results. You’ll only need a hacksaw to cut this wrap-around seal into size. You will then pull its top flaps and attach them to the upper part of the garage door.

Its design implies that the seal works best when the door is closed, blocking all unwanted noise and cold breezes. Besides, you cannot pull it off when the door is closed. It also ensures that no heat leaves the garage, keeping you warm at all times.

Threshold Seal

You’ll use threshold seals between the floor and the bottom part of your garage door. Typically, they aim at preventing the garage from strong winds, rain, and heat. These seals could be made from either aluminum or rubber, each option assuring you of value for your money.

Fitting the threshold seal will barely give you a tough time. You’ll place it behind the garage door, where it forms a tight seal whenever the door closes. Ensure that you notch it around the door channels or the door frame. You must also clean the surfaces before you install the threshold seal.

Putting it in front of the door could stop water from running down the face of the door. Otherwise, the water could end up between the seal and the garage door. The installation process is straightforward, meaning any DIYer with basic skills will fix it.

Threshold seals come in various sizes. Ensure that you measure the distance between the surface and the bottom part of the garage door. This move ensures that you get a seal that can comfortably protect your garage from unwanted water and cold breezes. A bigger size will often be an excellent choice.

Insulate the Garage

Excellent insulation helps improve the comfort of your garage, from minimizing cold and noise to keeping critters away. This method is effective yet significantly affordable. However, this effectiveness will vary with the materials you use. The choice is often between fiberglass and foam board. You could also consider reflective insulation, which offers unrivaled thermal performance.

Fiberglass provides better energy efficiency, reducing your utility costs in the long run. It also ensures that very little noise comes in or leaves your space, maintaining your comfort. This material shields your garage from excessive moisture, sound, and air. In contrast, you can use foam board insulation on a relatively thinner layer.

After you choose your preferred insulation material, you’ll need to install it. The installation process is straightforward, meaning you do not need professional help. All you’ll have to do is place the insulation panels on the frame, where the foil must face the garage door. It would also be beneficial if you started the installation from top to bottom.

Final Thoughts

No one wants to stay in a noisy garage, and neither do you want your garage to be susceptible to critters, moisture, and wind. Understanding how to handle these elements ensures that you remain comfortable and peaceful. The methods mentioned above will help keep your garage less noisy. Ensure that you choose whichever provides you with the best experience yet affordably.
