If your basement has flooded, you're going to need to get the water and moisture out as quickly as possible. Water can do more harm to your home than you might realize. The longer your home stays moist, the greater chance it has of developing mold. Mold is more than just an unsightly nuisance. It also poses a health risk, especially if you or members of your family suffer from allergies, asthma or other breathing problems. Once the water has been removed from your home, you'll need to start on the mold clean-up. Here are a few steps that will help you get rid of the mold and prevent re-growth.

Thoroughly Wash All Exposed Surfaces

Even if you can see water, there could still be moisture inside the walls and floors. Mold can grow on virtually any surface, including concrete, wood and drywall. Since you can't see mold spores, it's important that you thoroughly clean and sanitize all exposed surfaces in your basement. Here are the steps for cleaning your basement walls and floors.

  • Basement Walls. You're going to be cleaning with bleach, so the first thing you should do is open some windows. You'll need a bucket, gloves, hot water, bleach and a stiff bristled brush for this cleaning project. Put your gloves on and fill your bucket with hot water. Be sure the water is as hot as you can stand it without burning you. Use dishwashing gloces if needed. Add 3 cups of bleach to the water. Use your brush to scrub all the areas of the walls that came in contact flood waters. Once you've scrubbed all the walls, allow them to air dry.
  • Concrete Basement Floors. Your concrete floors are going to need a thorough cleaning too. The easiest way to clean your floors is to use a garden sprayer. You'll use the same cleaning solution that you used for your walls. Simply mix the hot water and bleach in your bucket and then pour the solution into your garden sprayer. Spray a thick layer of the solution on your entire basement floor and allow it to air dry.

Seal the Concrete

Now that the concrete surfaces in your basement have been cleaned with bleach, it's time to seal them with a waterproof sealant. The sealant will prevent mold growth and protect against future water damage.

Supplies You'll Need

  • Disposable paint pan
  • Paint rollers
  • Waterproof concrete sealant


  1. Fill your disposable paint pan with sealant.
  2. Use your paint roller to apply sealant to all the concrete walls.
  3. Starting in the corner of the room farthest away from the door, roll a thin layer of sealant to the entire floor.
  4. Allow it to dry overnight.
