Garage Door: Bottom Seals
Bottom Garage Door Seal - Measuring and Buying Tips
If you have a steel garage door that's been on your home for a while
then you most likely have a bottom seal on the garage door that is
cracked, hardened or torn. Years of being in the elements can damage the
seal along with chipmunks & squirrels that want to get in your
garage for that birdseed you have sitting in there. You'll be able to
seal up the garage, keep out the elements and hopefully the critters by
replacing the worn out seal with some new seal.
Figuring out what bottom garage door seal will work with your door is not difficult but it can be frustrating so
we'll go through some steps below that will hopefully take away some of
that frustration.
Determine What Style of Seal You Need - There are different
styles of seals. There are some common ones that many manufacturers use
and then a few odd ones. You'll need to determine what seal you need and
it's best if you can cut a piece off of the existing bottom seal. Raise
you door part way so you can reach the bottom seal and if you can cut a
2" to 3" piece of the seal off (scissors usually work well). Also take a
few pictures of the seal and retainer (that's the aluminum piece the
seal slides into) so you'll have a couple of pics to send us if you decide to contact us for help. A few pics can sometimes help us assist you in determining what seal you need.
Measure The Bottom Seal - Take the piece of seal you
cut and use a measuring tape or ruler to get some measurements.
- Measure the width of the seal as it lays flat. The most common widths are 3" and 4" (but could be anywhere from 2-1/2" to 4-1/2").
- Determine what "style" of seal it is. Probably the most common "style" is the T-style but there are also P-Bulb style, Bead style, T-Bulb style and others. On the T-style seal these are the parts of the seals that look like a "T" and slide into the bottom seal retainer. You'll want to measure these T's on the seal as this will determine which seal will fit into the bottom seal retainer. You're basically measuring the side of the seal. Write down your measurements. The most common "T" measurements are 1/4" and 5/16".
Measure the Width of the Garage Door - You'll want to measure the width of the garage door so you can determine the length of seal you need. Don't measure
the garage opening as your garage door may be slightly larger than the door opening. Single car doors can be 8'
to 12' wide while 2-car doors can be 16' to 20' wide. Garage doors can
be made any size though in 1" increments so that's why it's important to
measure the door and not the opening.
Order New Seal - Now that you have all the measurements you can order replacement seal. If you have the T-style seal then you can order some replacement seal from us at the Garage Door Zone. If you measured the "T" on the seal to be 1/4" then you have a couple of options: 3" wide vinyl seal, 3" wide rubber seal, 4" wide vinyl seal and 4" wide rubber seal. If your "T" measures 5/16" then the only option we currently offer is the 4" wide rubber seal.
The 1/4" T-style seal is a compatible replacement for Raynor brand garage doors along with some Gadco, Hormann and other brands using a 1/4" T-style seal. The 5/16" T-style seal is more commonly found on some Amarr, CHI, Clopay, Wayne Dalton and Overhead door models.
- Difference between vinyl and rubber. The vinyl seal is going to be a little bit stiffer than the rubber seal. The rubber seal is going to be slightly better for extreme hot and cold temperatures. Both seals have ribs on the one side to help keep out the dust, dirt and water.
- Overall length of the seal. If you order seal from us then we will ship your seal with an extra 5" to 6". So if you order a 9' long piece of seal then the actual length of seal you get will approximately be 9'6". The extra seal is for tucking back into the retainer when you install it.
Still Not Sure What To Order? If you've taken the measurements but you're still not sure what to order then we recommend that you Contact Us. If you have some pictures of your bottom seal and retainer please include them. We'll do our best to help you figure out what you need. You can also order a Seal Sample Pack. We'll send you all four types of the 1/4" T-style seal we sell in 4" lengths. With the small samples you feel the difference between the vinyl and rubber seals plus you can see if the "T" part of seals fit properly in your garage door retainer. This will also help determine if our seals will work in your door without having to buy a long piece of seal only to find it doesn't fit your door and having to pay $9 or $10 to return it to us. The Seal Sample Pack includes free shipping.

Hi. I have three 8’ foot garage doors and I’m trying to find the correct replacement bottom seals for them. They seem to be smaller than the common seals that I see on the website. The original seal for the channels seem to have a 3/16” slightly rounded top lip, but not quite a T. Naturally, the old ones are stiff and hardened, but are less than 2” for the bottom floor contact and has 7 ridges that run the 8’ length. Also, I live in S Fl and would like your suggestion for what material is best for sun and heat. Hope you have a product that would work. I can also be reached at (954) 796-8411 if I can answer any questions. Thanks

It doesn't sound like your doors use the 1/4" T-style seal that we sell. If you want to send us some pictures of your bottom seal that shows the part that slides into the seal retainer on the door then perhaps we can help you determine what type of seal you have. You can send your seal pics to us at [email protected]
