Not pleased with the standard vinyl weatherstrip that is installed on most garage doors? Me either. It seals well enough but they discolor, you can't really paint them, and depending on how they are installed they often warp and just look bad. When I had some new garage doors installed last year I asked the door company what other options I had. They told me if I didn't like the standard weatherstrip i should just not install it. I'm in a cold climate, and I like to use my garage year round so I couldn't just go without. I ended up ordering the plastic stuff because i didn't know what else to do, but I just wasn't happy with it and never put it up. It's still in a box in my garage if anyone wants it, i'll give you a great deal.
The other day I decided I was going to do something about this situation before winter hits again. I ordered some Pemko Bronze colored weatherstrip (Pemko Q102D 121 Inch Length Weatherstrip) that is generally used on exterior man doors. We don't have it on our website, but we can order some in for you if you like, just contact us. It's relatively inexpensive weatherstrip and just mounts into a saw kerf.
My doors are trimmed out in Smartside siding, so I orders some 1x4 Smartside trim for this little project. Using my table saw I cut a 5/8" deep kerf in the edge of the 1x4.
With the kerf cut it's really easy to install the weatherstrip, just press the ribbed edge into the kerf all the way down the 1x4.
I debated for a couple of months if this type of weather strip would work on a garage door. I was worried that as the door came down it would push the weatherstrip down and out of the kerf. However, if you watch your garage door close it comes down at a slight angle towards the ground and the door isn't completely vertical until it hits the ground. I closed my doors and lightly tacked the 1x4 with weatherstrip against the door making sure it was compressed slightly between the board and the door to assure a good seal. After opening and closing the door a few times, testing the seal and making sure it wasn't obstructing anything I used some longer finish nails to solidly attach the 1x4 to the jamb. I just need a little caulk and paint and we'll have a nice clean seal with no warping or discoloring. This was a simple project to do and really not very expensive.
