31 Days of Handy Home Fixes | Pretty Handy Girl


Do you have a garage? Are your garage doors insulated or weather stripped? Or do you have big gaps in the sides like this:


If you don’t have weather stripping on your garage doors, you could be throwing away money on heating spaces above and/or next to your garage. Not to mention, making it uncomfortably cold for any of us Handy Peeps who work in the garage.

Day 26 – Weatherstrip Your Garage Doors

In an hour you can seal the gaps around your garage door. This could make a huge difference in the temperature of your garage. And you could improve the temperature in adjacent rooms. After installing the weather stripping we noticed a huge difference in the temperature of our bonus room that sits on top of the garage.

Garage Door Side and Top Weather-strip Kit costs less than $20. Be sure to measure the sides and top of your garage doors and order enough to cover.

Use the nails included in the kit to secure the garage door seal against your doors.

For a time saving tip and more detailed directions you can follow my full tutorial for installing garage door weatherstripping.

These were the resulting temperature shifts after I installed the weather stripping on our garage doors:

Before Weather Stripping:

Outside Temperature Inside Garage Temperature Temperature Difference
45˚F 55˚F 10 degrees
30˚F 45˚F 15 degrees


After Weather Stripping: 

Outside Temperature Inside Garage Temperature Temperature Difference
45˚F 65˚F 20 degrees
30˚F 58˚F 28 degrees


Go ahead and seal those gaps and enjoy a warmer garage and home this winter.

    This is such a relatively easy fix, but it’s something that I’ve never thought to do! I have a very old (and drafty) house with original windows and casings, so I’ve addressed those, but I never thought to address the garage door. I’m going to have to give it a go. Our house gets so cold in the winter, so if we achieve the same results you did, I will be a very happy lady.
    As a side note, your doors themselves are beautiful!

    Brittany, I received and installed the weather stripping for sliding doors and it is AWESOME! Thank you SO much for the tip and link! The company is also absolutely delightful.
    Happy creating,

    What about the bottom, where the garage door meet the garage floor? I have about a 6 foot section where the floor just isn’t level. The rest of the garage door fits fine. Is this something to worry about? Can I even fix just the 6 feet? I’m unable to take on any large projects health wise. So here’s hoping…. I’m glad I found your site. I wish I had your tools!

    I have weatherstripping around my garage door but it is mildewed and nasty. I would love to remove and replace it. Is it easy to remove? If I replace it, do you have any good ideas for keeping it from mildewing again? Thanks for all your tips! You make it all look so simple.

    Brittany, I am really enjoying these tips… and your whole blog! This garage door tip is, I hope, adaptable to sealing the gap in my apartment sliding glass doors. Windy winter days send the very cold air sailing through the gap between the double pane sliding doors.
    I’m also thinking about using some pipe insulation to fill in the gaps around the window (or wall in my apartment’s case) air conditioning unit. The foam in there presently is less than adequate. I’d like to avoid encasing the entire inside portion in plastic like I did last year.
    Thanks again… you inspired my creative wheels to turn!
