Mold Control & Prevention Tips


Moisture control is the key to mold control. The following tips will help prevent moisture, condensation, and water problems throughout the house:

testing mold removal

Water stains on ceiling are tested for mold before repair and painting.

• When water leaks or spills occur, act quickly. If wet or damp materials or areas are dried within 24 to 48 hours after a leak or spill happens, in most cases mold will not grow.

• Clean and repair roof gutters regularly.

• Make sure the ground slopes away from your home’s foundation so that water does not enter or collect around it.

• Keep air-conditioning drip pans clean and drain lines unobstructed and flowing properly.

• Keep indoor humidity low. If possible, keep relative humidity below 60 percent, and ideally between 30 and 50 percent. Relative humidity can be measured with a moisture or humidity meter—a small, inexpensive ($10 to $50) instrument available at many hardware stores.

• If you see condensation or moisture collecting on windows, walls, or pipes, immediately dry the wet surface and remedy the moisture/water source.

• Vent appliances that produce moisture, such as clothes dryers, stoves, and kerosene heaters to the outside where possible.

• Employ air conditioners and/or dehumidifiers when needed to reduce humidity. Increase the air temperature to reduce condensation.

• Run the bathroom fan or open the window when showering. Use exhaust fans or open windows when cooking, running the dishwasher, or washing dishes.

• Cover cold surfaces, such as cold water pipes, with insulation.
