I have a 2.5" gap under on small area of my double garage door. I
can't seem to find a bottom door sealer over 1.5" thick. Where can I
find a garage door "foam material" that will be 2.5" thick and will
compress completely in the areas of the door where there is no gap?
Thanks for any help!
A picture would help. Is the gap all the way across? Then you need
to adjust how far the door closes. Is the gap at one end? Then you
need to adjust the door mounts so it closes evenly against the
bottom. Is you floor so uneven that you have a 2.5" gap in one spot?
You're not going to find anything like that, because it's the wrong
solution for the problem. Home Depot sells a lot of band-aid solutions
that encourage people to do bad things to their homes, but even they
know that what you're trying to do is beyond ridiculous.
Do you put band-aids on bullet wounds?
The correct solution is to fix the hole in the floor.
the garage is not all that a mysterious thing to do...
There could be other reasons why the floor is level and flat.
Obvious holes can be patched. But it's not unreasonable to apply a "filler
strip" to the edge of the door which is cut so that there is a uniform and
bridgable gap. THAT gap you close with weather stripping.
What I pictured was not a hole in the floor but more likely a set of tracks
that need to be adjusted so the flat bottom edge of the door will hit the
flat door. Alternatively there is something stopping the door on one side
that the OP has not noticed.
It is doubtful the original owner would have accepted the concrete job that
About the time I had mastered getting the toothpaste back in the tube, then
Mine was done poorly. The concrete dips down in the center of the door.
Didn't realize it when I did it, but the opener actually crushed a
little of the steel door on one side so now it is sealed in the center
too. A strong door too, steel on outside and inside with insulation in
the middle. Yes, I backed off the closing pressure adjustment!
Upholstery foam. + duct tape, proly.
They can cut upholstery foam (white, yellow-ish) pretty accurately.
However, I sort of agree with mkirsch -- 2.5" is pushing the definition of a
But, if you really can't fix the floor/foundation, foam will at least fix
the air/humidity/infiltration problem, for a while.
If this is going to be a longterm solution, think of ways to weather proof
the foam, by wrapping it in 3 mil plastic or some such.
They make a sealing rubber strip (not foam) that you might want to put on
the bottom of the foam, as well. Almost looks like "channel".
You might even be able to scavenge this foam from cheapie mattresses, or old
You'll want to counterbore this material for a screw and 1/2"-1" washer, and
screw from the bottom. As you do this, you proly won't get a perfect "mate"
between the foam and the door, but no matter, when the door closes all will
Another long-shot material possibility is rubber tubing, such as used on
industrial rollers etc, which is a long shot bec this is very expensive
material, but you might find some in a dump, or factory, etc.
I happen to have a bunch from an old machining job, and it's great stuff.
Just loosely stuff it with cloth or old foam scraps, etc, just to give it
some body. You wouldn't be able to counterbore this stuff, but a flat head
screw and washer from the bottom would still be the way to install it.
