How to Clean Mold on the Joist

Mold on joists in your home may lead to health issues, including respiratory problems, such as coughing and asthma, watery eyes and skin irritations. Mold releases spores that can enter your lungs during respiration, and regardless of whether the spores are alive or dead, they may cause serious issues. Water leaks and high humidity tend to produce mold spores, which thrive in moist conditions. Therefore, removing what causes mold is as important as the mold itself. Additionally, if the mold occurs in a hidden, unreachable area, a professional may be necessary.

     Mix 1 cup of bleach with 1 gallon of water in a large container.

     Fill a spray bottle with the mixture. Set the sprayer to "mist."

     Wet the joist with clean water where the mold is and wipe it with a cloth, removing any spores on the surface. Avoid scrubbing or rubbing the spores; this may cause them to spread through the air.

     Spray the infected joist with the bleach mixture. Do not over saturate the wood joist. Continue to wipe the area with a cloth until no mold remains on the joist.
