Ask All Island: What can I do about water in my garage?

Water in your garage? Here’s why that’s a problem and what to do about it

Has this ever happened to you? You go out to the garage after a rainstorm, only to discover it’s flooded with water. If so, you’re not alone. Water can cause serious damage to garages, which is why it’s important to protect yours from the elements.

Common issues from water in the garage  

Cost: Water damage to the garage can add up. Not only can it lead to increased insurance premiums (which over time can accumulate and be costly), but you’ll also have to pay for repairs – which can include anything from flooring and subflooring to electrical. And yes, even the garage door itself might need to be repaired or replaced.

You’ll also need to factor in the cost of replacing anything of value you’ve stored in the garage that sustains water damage. Whether it’s a bike or tools, replacing these important items can really add up.

Structural damage: If you notice discoloration or erosion in your garage after rain, you could have structural damage that will need to be addressed. This type of damage is particularly common in older garages. Without the necessary repairs, the structural damage could lead to a garage that’s simply unsafe to use.

Mold and mildew: Standing or accumulated water can cause mold and mildew in the garage. If you notice a stale or musty smell, there’s a good chance that you have mold in the area. Not only can this lead to structural issues, but it can cause health issues if not treated.

How to prevent water damage in the garage

Check your garage sealing. One of the most common reasons garages sustain water damage is because of faulty seals. Check your garage door for any gaps where the ground and door should meet. Look for light coming through around the garage door and check for water after it rains. If you notice signs of water entry, apply weatherstripping or contact a garage door professional to replace the seals. Never replace seals on your own!

Add ventilation. All garages need appropriate ventilation. Make sure your garage windows are sealed and working, install a fan system, or place a dehumidifier in the garage to prevent mold and mildew.

Have a drainage system. Like ventilation, your garage should also have a working drainage system. Rainwater needs to drain away from the garage and home, so check your drain and catch system for clogs and consider adding extra drainage if needed.

Check the roof. If the garage and garage door look fine and you can’t find the reason water is entering the garage on the ground, look up. There’s a chance you have a leak in the roof. We recommend checking the roof every few months and removing any debris such as branches and leaves, which can lead to roof damage.
