How to Kill Basement Mold How to Kill Basement Mold

What You'll Need
Paper towels, rag or sponge

Basement mold can be a serious problem. Mold, while not particularly resilient, can return very quickly, even when is has been cleaned properly. A few varieties of mold can cause health problems. Even everyday mold can cause damage to food, paper, drywall, and other materials. Follow these steps to have a basement that is absolutely mold free.

Step 1 - Cleaning

Killing mold that is already visible is quite easy. A simple borax solution is enough to do it. Borax is a common cleaning material. Unlike bleach, it is capable of killing mold on porous surfaces. Additionally, borax does not release harmful fumes; however, it is toxic, so keep your children and pets away from it.

  • Mix 1 cup of borax with 1 gallon of water.
  • Apply some of your mixture to your rag, sponge or paper towel, and wipe the effected area. A few wipes should be enough to do the trick.

In serious cases, you may need to give up on cleaning altogether and simply replace the moldy materials. Obviously, you do not want to have to do this repeatedly, so be sure to immediately put the next steps into action.

Step 2 - Removing Humidity

Mold needs humidity to grow. Because your mold is now gone and you are trying to prevent it from coming back, the best thing you can do is keep your basement free of humidity. Installing a dehumidifier should do the trick. Dehumidifiers are relatively simple. They only require that you plug them in and leave them alone to do their jobs correctly. Start your dehumidifier on its lowest setting and turn it up as needed.

Many dehumidifiers consume a lot of power. An air conditioner can serve as a dehumidifier in a pinch, so if you have one, try it out first to see if it is enough to remove the humidity from your basement. If not, try a dehumidifier.

Step 3 - Additional Problems

Sometimes, a dehumidifier is not enough. In these cases, it is likely that your basement has more serious problems than simple mold or high humidity. Check your basement pipes for leaks, cracks, and other problems.

Additionally, a leak or problem in another area of your home could also be causing the problem. If you find the problem and it is beyond your ability to solve, or you are just completely unable to figure out what is causing your basement to be so humid, you should consult a professional.

In some cases, basement humidity will come from something outside your control, such as a high water table.
