Garage Door Bottom Seal
Choosing A Quality Seal

A garage door bottom seal is very important for keeping drafts, dust and debris from getting into your garage. It also acts as a cushion for the bottom of the door, and protects it from being battered by your concrete floor every time the door goes down.

Because of all of this, it is important that you choose a good, high quality door seal, but also one that won't break the bank. You can not only find an abundance of different seals, but they are not that hard to replace, so you can do it yourself.

The first step is to examine the bottom of the garage door itself. Check the bottom seal for damage, wear and tear, and how it is mounted. You are going to need to measure the bottom length and width of the door itself, so you can buy a replacement seal that is at least the same size.

Some seals come in pre-measured lengths and widths, others come on a roll. While pre-measured sizes are good, a roll of the seal can be more cost effective in the long run. When you have more than one door, or use the door often, you may need to replace the seal more often, so having a roll standing by can come in handy.

The type of door plays an important factor in choosing the right garage door bottom seal as well. A metal door will have screws, while a wood door may have either screws or nails attaching the seal. Some doors have a metal runner, and the seal simply slides into place. If it doesn't, you may want to think about getting one, so that it is easier to replace the seal whenever you need to. Once in place, you just slide out the old one and slide in a new one, cutting it off at the end.


While most garage door bottom seals are made from a rubber material, they are not all made the same. One kind is a flat rubber seal, another is a tube like seal that flexes when the door comes down.

While flat seals are going to be less expensive, a tube seal can be beneficial in different ways as well. They seal the air and debris out, but they also provide an added cushioning layer between the floor and the bottom of the door. Even if your garage door opener goes out of adjustment, your door will still be okay.

There are many retailers that offer a garage door bottom seal, but for the best prices and selection it is a good idea to go online first. One of the best places for buying seals is Amazon. They have a pretty good selection of seals, and may even have the lowest prices.
