What Do Garage Door Seals Do?
A garage door has several seals, and each closes a different gap. The bottom seal presses against the floor when the door is shut. Weatherstripping, sometimes called stop molding, runs down both sides and across the top and seals the gap between the door and the frame. Together they keep out rain, insects, dust, noise and hot, humid air.
They also protect the door itself. A bottom seal that makes full contact stops water from sitting against the bottom edge of the bottom panel, which is where rust and rot start. Our panel repair page covers what happens when that goes wrong.
Signs Your Garage Door Seal Needs Replacing
- Daylight showing under the door when it is closed
- Water running in, or pooling inside, after heavy rain
- Rubber that is cracked, brittle, flattened or torn
- A bottom seal that has slipped out of its retainer and hangs loose
- Insects or other small visitors getting into the garage
- A hot, humid garage with a musty smell
- Gaps or loose flaps in the side and top weatherstripping
In South Florida, a seal that is a little worn is a much bigger problem than it would be somewhere drier. Afternoon downpours are fast and heavy, and they find every gap.
Types of Garage Door Bottom Seals
| Seal type | How it attaches | Good to know |
|---|---|---|
| T-style | A T-shaped end slides into a channel on the bottom of the door | A common modern fit that needs the right retainer |
| Bulb or bead style | A round or beaded edge slides into a one- or two-channel retainer | Fits many steel and aluminum doors |
| J-style | A J-shaped end fits into a retainer on older door styles | Often found on doors of an older design |
| Threshold seal | A rubber strip fixed to the floor, not the door | An extra barrier, useful on a sloped floor, and used with a bottom seal |
The seal has to match the retainer on the bottom of your door, and the door’s width decides the length. We identify the retainer type and match it, because the wrong seal will not hold or will not seal.
Why Does Water Get In During Florida Storms?
A worn seal is the most common cause, but it is not the only one.
- A seal that is flattened, cracked or no longer touching the floor
- A slab that slopes toward the door, or a driveway that drains into the garage
- A door that does not travel all the way down because the limit setting is too high
- Wind-driven rain pushed through gaps at the sides or top
- A damaged or bent bottom retainer that holds the seal at an angle
A seal stops rain and splash. It will not hold back standing floodwater, and a sloped slab or driveway is a drainage problem a seal cannot solve. We tell you which problem you have.
What About the Side and Top Weatherstripping?
Side and top stripping seals the sides and head of the opening. It is usually vinyl or rubber flaps fixed to the door stop, and it dries out and cracks with sun and heat. When the stripping is loose or missing, light, rain and insects come in at the sides.
If the wood door jamb behind the stripping is soft or rotted, new stripping will not hold, and the jamb needs repair first. We check the frame as part of the job.
What Happens During a Seal Replacement?
- Check the gap. With the door closed, we look at where the seal meets the floor and where light shows.
- Identify the retainer. The seal type has to match the channel on the bottom of the door.
- Remove the old seal. The retainer is checked and replaced if it is bent or corroded.
- Inspect the bottom edge. We look for rust or damage that was hidden under the old seal.
- Install the new seal. It is cut to length and seated along its full width.
- Set the down limit. The door should close fully and compress the seal without straining the opener.
- Replace side and top stripping if needed.
- Test. We check the closed door for light, run the auto-reverse and confirm the door closes cleanly.
Seal Replacement Before Hurricane Season
The bottom seal and weatherstripping are part of the pre-season check, along with the springs, cables and sensors. Before June 1, it is worth confirming that the seal makes contact across the whole width and that the stripping is intact. Our maintenance page explains the full checklist, and if the door itself is old or damaged, our impact door page explains the options.
Frequently Asked Questions
How long does a garage door seal last?
Several years in many climates, but heat, sun and salt air shorten it in South Florida. Cracking, flattening and gaps are the signs, and a quick look each spring catches them.
Can I replace the bottom seal myself?
It is one of the simpler garage door jobs, but the door must be secured, and you should not touch the bottom brackets or the springs. If you are not sure of the seal type, we are happy to identify and replace it.
Will a new seal stop all water from coming in?
It stops rain and splash that come through the gap under the door. It will not stop floodwater, and a sloped slab or driveway is a separate drainage problem.
Why does my seal keep coming out of its track?
The seal may be the wrong type for the retainer, the retainer may be bent, or the seal may be too long or too short. We check all three.
Can a new seal make the door reverse?
Yes, if the down limit is set too aggressively, the door may reverse when it compresses the seal. We set the limit so the door closes fully without tripping the safety reverse.
Do you replace side and top weatherstripping?
Yes. We replace stripping that is cracked, loose or missing and check the jamb behind it.
Water getting in?
We match the right seal, set the door to close fully and test it before we leave.
