DIY #3: Garage door weatherstripping

We’re not talking about the stick-on foam kind here, but the tack-on vinyl stuff, which is much longer-lasting although harder to put up. It’s still pretty easy.

I bought a package of garage door weatherstripping for about $20. It comes with enough to do sides and top of a double garage door, and comes with packages of the tacks/brads you will need. Your only other tools are a hammer, ladder, and scissors. You may need your garage door opener, too.

I wanted to add weatherstripping because of the gap alongside my garage door, which you can see in the picture below. It seemed like a way for mice, snow, and cold/heat to get through. Due to the configuration of the door, I wasn’t able to install it on the inside of the garage, and put it on the outside. You may be able to put it on the inside, but watch out for roller mechanism for the door.

The stripping has a narrow side and a wide side. You want to arrange it so you are nailing the narrow side up to the garage door frame and the wide part is up against the door. Tack up the top first, then cut it off at the bottom a little long. You can leave it long or trim it later. Due to stretching, the piece will probably get a little longer as you nail it on.

By the way, here’s a good way to hold brads and nails, in case you didn’t know. It’s easier to get in to tight spots this way and less hard on the fingers during the beginning taps.

Starting at the top, nail the strip down the frame, checking to make sure the wide part is right up against the door. Put a nail in about every eight inches or according to your weatherstripping’s instructions. You may need to make adjustments depending on how your door rides up the carriage. For example, my door has a larger gap on one side than on the other (it’s old). The bottom sill would ride over the weatherstripping on one side, but on the other, I had to cut a notch for the sill to fit into so it wouldn’t crush the weatherstripping.

You’ll also need to cut a notch in the top, or an angle, so the door won’t catch on the weatherstripping on the way down. This also allows for the top piece to be fitted in snugly if you are going to add a top piece.

Check to make sure everything is going smoothly. Keep your garage-door opener in-hand while you’re checking in case something goes wrong!

Hopefully this will help keep pests and weather out. You can do this on exterior doors, too – just make sure the door closes into the weatherstripping, rather than pulling through it.
