How to Winterproof Your Garage

After a brutally hot summer, you’re grateful for the cooling temperatures. The chillier weather allows you and your family and friends to spend a little more time outdoors, and you can finally get to all of those projects you’ve postponed due to intense heat waves.

While you create a schedule for finishing those crafts and projects before winter sets in, you may want to add garage winterproofing to your list. This maintenance will ensure your garage and all its components work properly even if it’s snowing and freezing outside.

Read on to discover what simple steps you can take now to keep your garage completely functional over the next several months.

Insulate Your Garage

You’re no stranger to the cold. During the winter, you love to sit in your warm home to evade the cooler temperatures. But when you have to leave for work or run errands, you’ll have to walk through your garage to get to your car. If your garage isn’t properly insulated, the space may feel like an icebox-and the cold air can move into your home, causing your home’s interior temperature to drop.

To keep your garage-and subsequently, your home-warmer, insulate your garage. Add insulation to the walls and the inside of the garage door if possible. If you can’t add insulation to the door, consider replacing it with a door that has insulation already installed in it. You’ll also want to insulate any pipes in your garage to prevent them from freezing or bursting in the space.

Depending on your budget, you can add foam board insulation, blown-in insulation, or batt insulation throughout your garage. Not sure which option is best? Ask a garage door professional so you can purchase the right material for your needs.

Improve the Sealing

Likewise, any cracked or holey sealing in your garage can affect the internal temperature of your garage. The damaged sealing can also allow moisture to enter the space, and that moisture can freeze in your garage if the area gets cold enough.

Look at the base of your garage door and inspect the rubber lining. If it’s cracked, crumbled, or otherwise damaged, replace it. Also, inspect the sealing around your windows and entry doors, and add new caulk or weatherstripping to keep the entire space tightly sealed during the winter.

Install a Heater

While insulation can keep your garage warmer during the cold months, the best way to keep the space toasty is to install a heater. You can hang this heater from the ceiling or it can stand freely on the floor. Visit your local hardware and appliance store or talk to a garage contractor and see which option will work best for your garage.

The heater will keep the area warm so you never have to worry about too cold of temperatures. Additionally, the heater prevents any moisture in the garage from freezing and causing other damage. If you store out-of-season clothing, books, or other belongings in your garage, the heater will also protect these items while they’re in storage.

Add Ventilation

Again, you don’t want moisture to get into your garage. If water gets into the space and freezes, you may have problems opening your garage door. The water could also freeze around the pipes or into the flooring. The water will expand once it freezes, and that process could cause issues like cracked flooring or burst pipes.

To further safeguard your garage from moisture damage, ventilate the area. Install wall vents on two opposite sides of the garage to allow air to flow freely. The added airflow will evaporate any moisture and keep your garage safe from damage.

Oil All Moving Parts

One of the worst things you can experience during the winter is a stuck garage door. If you can’t get out of your garage, you may be late for work or other obligations. Instead of risking this issue, oil all moving parts on the garage door so it can open and close freely and without difficulty. Talk to a garage door expert to determine which kind of oil you should use.

Stock up on Salt and Snow Shovels

Designate a small area in your garage to store rock salt and snow shovels. Lay down salt in front of each side of your garage door to prevent those areas from freezing. If you get any snowfall, shovel it away from your garage door as soon as you are able. If you can prevent the snow from building up too much, your garage door will work more effectively during the season.

Schedule Needed Repairs

If you’ve put off any garage door repairs, schedule them as soon as possible. Replace worn-down springs, broken remotes, or dented doors. If you wait until your garage door stops working, you may have to wait longer for a solution since winter weather and temperatures can delay technicians.


Take the steps above to prepare your garage for winter. As the temperatures continue to drop, you won’t have issues getting into and out of your garage. If you do need to schedule any repairs, talk to the experts at AAA Garage Door Inc.
