Question

What are tips to control mold around the house?

Answer 1

Around the house:

• Use dehumidifiers and air conditioners, especially in hot, humid climates, to reduce moisture in the air.
• Keep indoor humidity below 60% if possible. You can measure relative humidity with a hygrometer, an inexpensive instrument available at many hardware stores.
• Keep air conditioning drip pans clean. Make sure drain lines are free of obstructions and flow properly.
• Keep the house warm in cool weather. As the temperature goes down, the air is less able to hold moisture and it condenses on cold surfaces, which can encourage mold growth.
• Add insulation to cold surfaces, such as exterior walls, floors, and windows to reduce condensation.
• Dry wet areas within 24 to 48 hours to prevent mold growth.
• Fix leaks and seepage. The ground should slope away from your house. If water is entering the house from the outside, your options range from simple landscaping to extensive excavation and waterproofing.
• Have a heating and cooling contractor check your heating and cooling system to make sure it's sized and operating properly to remove humidity. If your system is too big or the airflow is incorrect, your air conditioner will not remove humidity like it should. Also, ask the contractor to check your duct system for air leaks, and proper size and air flow to each room.
• Open doors between rooms to increase circulation, which carries heat to cold surfaces. Increase air circulation by using fans and by moving furniture from wall corners.
