How To Get Rid of Mold in Your Basement

The only way to get rid of mold in a basement is to fix the water problem. Otherwise, it will always come back. You then need to clean and disinfect the area. You can safely kill basement mold if it is less than a few square feet. However, you should hire a mold remediation company for larger spaces.

1. Fix the Water Problem

Mold is always caused by a water problem. If you don’t repair that first, the mold will come back in weeks or even days. Usually, you need to fix a leaky pipe or clean out clogged drains, but you may need to waterproof your foundation.

2. Throw Away Damaged Materials

Next, throw away anything that is damaged or covered in mold. Use heavy-duty garbage bags, or you can spread mold throughout your home during cleanup.

3. Dry Your Basement

Even a little water will allow the basement mold to grow, so make sure your dry your basement thoroughly. High-volume fans and drying dehumidifiers are the best tools for drying your basement.

4. Clean and Disinfect

Once your basement is dry, you need to kill any remaining mold. Add one cup of bleach to a gallon of warm water, then spray down anything with mold. While bleach is safe, the smell can be overpowering. We recommend wearing safety glasses, rubber gloves, and a face mask.

How To Prevent Mold in Your Basement

The best way to prevent mold in the basement is to check for leaks regularly. Since many basements have water problems, it’s also important to clean your basement often and disinfect it at least once a year.

Check for Water Leaks

You can help prevent basement mold by checking your pipes and appliances every month or two for leaks. Start at your water shut-off valve and follow your water pipes until they disappear into the floor. Then look around your hot water tank, furnace, air conditioner, washing machine, and dry. Check connection hoses and drain pipes as well. If you have a finished basement, look for water stains or soft, spongy spots on your walls.

Address Moisture Issues Immediately

Many basements have high humidity levels, so use a dehumidifier to help regular the moisture levels. If you have a basement bathroom, use an exhaust fan to help condensation. Clean up spills immediately and never leave water pooling on the basement floor.

Clean Regularly

While water causes basement mold, it is more likely in a dirty basement. Make sure you clean with soap and water every other month and disinfect with bleach every year. Take out the trash regularly as well.

Store Things Properly

Since boxes can soak up water and lead to mold, you should use water-tight storage containers to limit problems. Also, put them on metal or plastic shelves to keep them off the floor.

Have Your Home Waterproofed

If your basement walls are cracked or have water stains, you should waterproof your foundation to prevent leaks. While exterior waterproofing is the most effective, you can also waterproof your basement from the inside.
