If wind, rain, or debris are getting in under the garage door, you can replace the door's bottom seal to protect the garage. Garage door seals are heavy-duty rubber that blocks out the opening under the garage door.
I don't think I've ever found a seal that was not worth buying. They tend to be high-quality products. I chose the Universal Seal that was on sale. You can see the latest price of the Universal Garage Door Seal on Amazon.
Does Your Garage Door Have a Channel?
Most garage doors have a channel on the bottom where the door meets the floor.
If your garage door does not have this channel, it might have come off with age.
If you want to replace that channel, you can get an aftermarket replacement such as this one from Coplay Garage Door:
Channel and Floor Garage Door Seal Types
A garage door seal can go inside the channel at the bottom of the garage door, or directly onto the garage floor under the door.
If your garage door has a channel, you can get either type of seal.
If it does not, then you want a seal that sits on the garage floor, like the Universal I'm recommending.
The door closes into the seal, smashing it down to stop the outside from coming into the garage.
Does Your Garage Floor Have a Low Spot Under the Door?
If your garage floor has a deep dip under the door, a standard rubber seal will not fill that gap.
The best course is to re-surface the floor to get a good seal.
Get the tools to re-surface the floor in my article: Don't Fix Your Garage Floor Until You Read This.
If you choose not to fix the floor, you might get a proper seal if you:
- replace the door channel
- use a thick floor seal
How to Install the Door Seal
- Scrub the area under the door with a bucket of hot, soapy water and a scrub brush.
- Rinse thoroughly.
- Allow the area to dry.
- Close the garage door while you are outside.
- Use a pencil to outline the door from the outside.
- Go inside to run the pencil outline of the door from the inside.
- Open the door and apply the Liquid Nails inside the pencil lines.
- Place the rubber seal on the Liquid Nails
