sealing the door also provided extra security. The gaps on the sides were a prime entry point for insects, rodents, and even burglars.

I had to clean my garage door sides before sealing it. It was tough but necessary to protect from weather and look nice.

I gathered supplies: a bucket, warm water, dish soap, a scrub brush, and a rag. I wore old clothes and gloves for protection.

I hosed down the sides to remove loose dirt. Then, I mixed soap and water in a bucket and scrubbed with the brush. I scrubbed every part, especially the sides where dirt collects.

I rinsed the sides with the hose and dried them with the rag.

step 2: Measure the sides of the garage door

  • Shut the garage door and stand inside it.
  • Measure how long the sides of the garage door are. Measure them all, including the left and right sides.
  • Write down how long each side is.
  • Add up the total length of all the sides to find out how much weatherstripping you need.
  • Buy enough weatherstripping to cover all the sides of the garage door. Get a little extra to make up for any cutting you need to do.

Make sure you buy weatherstripping that works for your climate and is made for garage doors. If you put the weatherstripping on right, it will help you save money on energy bills, stop drafts and bugs from getting in, and make your garage door last longer.

I went to the store and got some foam weatherstripping that sticks to itself. It seals up gaps well and was easy to put in.

After that, I wiped down the garage door sides with a wet cloth to get rid of any dirt or junk. I let it dry out completely.

Then, I measured how long the sides were and snipped the weatherstripping to match using scissors. I made sure to have enough for every bit of the sides, even the corners.

  • Measure the weatherstrip needed for the garage side. Cut it with scissors or a utility knife.
  • Align the weatherstrip with the edges of the door. Ensure it’s flush and straight.
  • Use a drill with a smaller bit than the screws. Drill pilot holes through the strip and into the door.
  • Insert screws through the pilot holes and tighten. Don’t overtighten to avoid damage.
  • Repeat on the other side. Check if the door closes well and if the weather strips seal gaps.

step 5: fix the weatherstrip on the bottom

I had a tough time fixing the weather strip below my garage door. Yet, it was worth it. The fresh weatherstrip not only stops the chill and breeze but also blocks bugs and other unwelcome creatures.

step 6: use a caulking gun

I got a new weatherstrip and caulking gun from the hardware store. I never used a caulking gun before, but the instructions were easy. I removed the old weather strip and cleaned the area for the new one.

Then, I put the adhesive in the caulking gun and applied it carefully on the weatherstrip. I pressed hard to make sure it stuck well on the garage surface. I did same on the other side.

At first, the caulking gun was awkward, but I got used to it. The new weatherstrip was in place, and it would protect me from the weather. I was satisfied with my work.

step 7: testing

Pushing the button to open the garage door, I listened for any sound differences. I was happy to hear the door moving more smoothly than before. The usual creaking and grinding were no more.
