How to reduce garage condensation

Condensation can be a problem in areas of the house that don’t get heated, like your garage. Condensation happens when moisture in the air hits a cold wall and beads of water form. This water can then lead to damp, mould and other problems.

Mould and damp can have quite serious health implications, so it’s important to minimise your exposure to them. The good news is that there are some relatively simple things you can do to help. Read on to learn more.

Keep temperatures constant

Use a heater to just take the worst of the chill out of your garage during the winter months. If your garage isn’t already insulated then consider adding it but make sure that whatever insulation you choose comes with a vapour barrier to help keep your garage dry.

Dry your car off

If you’ve come back on a wet day, take a moment to squeegee off the worst of the moisture before you put the car away. This will help stop the water from evaporating into the air in the garage and turning into condensation as soon as it gets cold.

Make sure that air can get into and move around your garage. It can be helpful to use a fan to move things along. Don’t block parts of the garage with possessions, make sure they are properly stored on garage racking systems available from garage shelving equipment suppliers.


Check your garage out in all weathers to make sure that you don’t have a problem with standing water. It also helps for it to be raining when you check the integrity of the roof and doors. Fix any leaks as soon as possible.

Seal the floor

Paint the floor with a sealant product that will stop water from soaking into the concrete. There are coatings which contain particles that help with slipping when wet too, to make your garage floor safer no matter what the weather.

Install a dehumidifier

Dehumidifiers have a relatively small running cost and they are great for removing water from the air. If your garage has a tendency to be damp, or if you use it to house your washing machine and tumble dryer, then adding a dehumidifier makes a lot of sense. Although condensation can be a problem, there are plenty of things you can do!
