You likely store a lot of nice things in your garage: your vehicle, your workbench, your tools, and all your expensive toys and equipment. Unfortunately, nothing stops bad weather from destroying those things — nothing, that is, except for installing the right garage door bottom seal types.

There’s more to your garage door than meets the eye. It’s a little more complex than you may realize and comes with many parts, including the springs, opener, and every little mechanism that makes it move. With all those things, your garage serves the purpose of keeping your stuff safe and securely locked away. That’s why we have different garage door bottom seal types.

What Are Garage Door Bottom Seals?

Sometimes the door needs a little bit extra to help it protect the integrity of your garage. When bad weather comes along, there isn’t much stopping it from entering your garage and wreaking havoc. Since concrete floors aren’t always entirely even, it’s easy for water to seep in. That little extra help comes in the form of weather strips, otherwise known as gaskets or bottoms seals.

A garage door bottom seal is that piece of rubbery fabric that runs along the base of your garage door, keeping the weather out. From rain to snow to hail, a good weather seal will protect what you have stored inside and keep it all from getting damaged or destroyed.

How To Repair Or Install Garage Door Bottom Seal Types

It’s completely possible for the different garage door bottom seal types to become damaged or get destroyed. This can be bad news for the interior of your garage during a storm, so it’s important to know how to fix it or replace in the event of something like that happening. Before you start replacing the garage door bottom seal types, make sure you take extra precaution. Be careful with the garage door and don’t put your weight on it. Garage doors are surprisingly fragile, and the weight of a human can pull the whole thing down, leading to serious injury. Always make sure to use only the properly devised tools and devices to handle the job. Also, have someone there with you to make sure everything goes according to plan.

This works best as a two-person job, so be sure to have someone there to help you. The extra help can come in handy, especially while you are feeding the garage door bottom seals through their proper channels. You’re better off when someone is on the other end helping you pull it through. It’s also best to have someone helping you if you don’t already have the proper channel installed on your garage door and need to add a threshold. Only then will you be able to line it up properly. Whichever of the garage door bottom seal types you have, the steps to replace and repair them are mostly the same.

Measure The Bottom Of Your Garage

Before you go out and purchase one of the garage door bottom seal types as a replacement, make sure you’re getting the right size. Take close measurements of the garage door. Start with the width, then measure the length and height. These measurements will be important for the new replacement seal.

While you are out purchasing a new bottom seal, look into purchasing a rubber threshold. This will give it extra holding power.

Remove The Old Weather Trim

Before you install the new garage door bottom seal, you must first remove the old damaged one. You should always be careful before doing so, since removing it can result in scratched paint.

To start, open the garage door about 6 feet. This will give you plenty of room to work in. Next, you should locate the gap at each end of the garage door. They will be at the bottom lined up with the seal itself. Now take the bottom seal and feed it through one of those holes. Pull it all the way through, and it should come right off.

Clean The track

Before putting on the new weather seal, make sure that the track it slides into is perfectly clean. Because of all the door has been through, you can bet there’s a lot of dust, dirt, and even webs under there. You can get a stiff brush with metal fibers or mesh, and that should do the trick. Make sure you scrub hard, since a lot of that dirt and grime can be pretty caked on there.

Install The New Weather Seal

Once you have your new weather seal picked out and the old one removed, it’s time to replace it with the new one. All you have to do is push it through the track you pulled it out of. Make sure to lubricate the track first before you do, so you don’t damage it or the seal itself. You can use a few drops of dish soap. Push and pull it through the track until it’s lined up and in place.

If you don’t have a track for the bottom seal, you’ll need to install a threshold. Before you can do that, you need to clean off the garage door with degreaser and water. The bottom of the garage door should be smooth and residue-free. Using the hump of the garage door, roll the threshold into place and then cut to adjust and secure with adhesive.

To install the seal, line it up to the threshold and close the garage door. Take it slowly, as you’ll probably need to adjust the seal as you go.

What Garage Door Bottom Seal Types You Need To Know

You should know what you’re buying before you go out and buy it. When it comes to garage door bottom seal types, it isn’t “one size fits all.” Your garage door might be better suited for particular designs or types. Let’s say you have a T-shaped channel at the bottom of your garage door; you’ll need something properly designed to fit into that channel. If it’s a single channel, you’ll need something that slides in like a beaded bottom seal type.

With each type, there are still different styles. The garage door bottom seal types you’ll need depend on the shape of the garage door, but there are different styles from which to choose. There are some that are better at keeping the wind out and some that are better at keeping water and leaves out. They all do a great job at what they do, so look into whichever one you want. There are four different basic garage door bottom seal types.

Bulb

There are two different kinds of the bulb type garage door bottom: a T-shape, and a P-shape. Both provide a very tight seal, ensuring nothing comes in, and nothing goes out. That means you conserve a lot of energy, saving money in the process. The bulb garage door bottom seal type is good for even garage floors. It has a round, circular bottom, and a T-shape or P-shape on top.

These are made up of the most durable, weather-resistant materials that remain flexible in virtually any temperature or weather. So the bulb itself will always provide a perfect seal on even floors, keeping heat, cold, rain, snow, and leaves out of your garage. The bulb type perfectly conforms to the floor of your garage, guaranteeing that all the elements are kept out.

Beaded

The beaded garage door bottoms are typically 3 inches in width and are flatter than the other garage door bottom seal types. While they won’t conform to your garage floor like a bulb, they offer a very tight seal on perfectly even and flat garage floors. The style is ribbed on the outside to help prevent freezing on the ground and the product itself.

The beaded garage door bottoms are typically T-shaped and designed for double channel retainers with more circular grooves. It’s designed to slide right into the channel for easy and fast installation. Again, this one is best used for flat garage floors, as it doesn’t do well contorting to curvature and uneven ground.

J-type

The J-type garage door bottom seals are named “J-type” due to the "J" that is created on each side when the garage door closes. While typically used for shipping containers and storage units, the J-type application on a garage door bottom seal is much the same. It prevents wind and water from coming in with a closed door. It perfectly seals it in by essentially creating a rubber shield entirely on the outside of the door.

T-type

Similar to the beaded garage door bottom seal types, the T-type weather seals belong to a two-channel retainer. On each side, there are two T's that will lock into each retainer. Typically, the T-type will come down to form a U-shape, kind of similar to a bulb-type seal, but not closed-off on the top.

Also similar to the bulb-types, the T-types are great with uneven floors and do a pretty good job of conforming to the ground below it. The super tight seal at the bottom will keep out wind and just about all moisture from the rain.

Know The Difference Before Repairing Or Replacing

All garage door bottom seal types are affordable and easy to install, but that doesn’t mean you should or can go out and purchase whichever one you see first. Examine whichever retainer (if any at all) is on your garage door. Check to see if it’s a multi-channel or not. That will determine which style you can get.

They do come in different shapes and sizes, so once you choose the type and how it will fit into your garage door, shop around a little bit to find one that best suits your needs and wants.
