How to Control Moisture in Your Garage

A garage is not just a place to park your car anymore but a spot for all those extra things that need to fit in the house. While it’s a handy space, garages can also be tricky regarding moisture. Excess humidity can lead to problems like mould, rust, and damage to stored items. Thankfully, residential garage door makers and other experts have some savvy tricks up their sleeves to help out.


Increase Ventilation

Stagnant air can quickly become humid air. If your garage is blessed with windows, make it a habit to pop them open occasionally. This helps circulate fresh air and sweeps out any lingering dampness. And if your garage is currently window-free? Mull over installing a vent or even a small window. You’d be surprised at the difference a gust of fresh air can make.

Control temperature

It’s a delicate dance between hot and cold, especially when keeping moisture in check. When your garage feels like an icebox, you might notice condensation forming on surfaces. Conversely, if entering your garage feels like walking into a steam room, you’re likely grappling with high humidity, and employing a heater during those chilly spells and an air conditioner when the heat ramps up can aid in keeping the moisture levels balanced and your garage ambiance pleasant.

Use a Vapor Barrier

Think of vapour barriers as your garage’s shield against unwanted dampness. By installing these barriers on the walls and ceiling, you’re essentially blocking moisture’s entryway. It’s like having a bouncer for your garage, only letting the good stuff in.

Dry Your Wet Vehicle Off

We’ve all been there: dashing through the rain, grateful for the shelter of the garage. But parking a wet vehicle inside can unintentionally increase humidity levels. Once you’re safely inside and the rain’s pitter-patter subsides, take a moment to dry your car off. A quick wipe-down can significantly reduce moisture, keeping the air dryer and your garage happier.

Improve Exterior Drainage

The exterior of your garage plays a huge role in controlling moisture inside. Keep an eye on your gutters and downspouts. Water can sneak in if they’re clogged or not directed away from the garage, causing unwanted dampness. Regular checks and clean-ups ensure rainwater flows away, not into your sanctuary.

Use a Dehumidifier

When in doubt, dehumidify! A dehumidifier is a trusty tool in the battle against moisture. These devices work tirelessly, pulling excess water from the air and reducing humidity. Plus, with less smoke, there’s a lower chance of mould and mildew making themselves at home.


Your garage is more than just a storage spot; it’s an essential part of your home. And like any part of your home, it deserves care and attention. With these moisture-controlling strategies, you can ensure a dry, comfortable space. So, whether you’re working on a new DIY project or simply parking the car, you can do so in a moisture-free environment. After all, as the experts of garage doors and residential garage door makers suggest, a well-maintained garage is a happy garage.
