- Moisture control is the key to mold control,
so when water leaks or spills occur indoors - ACT
QUICKLY. If wet or damp materials or areas are
dried 24-48 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 the
building foundation, so that water does not enter
or collect around the foundation.
- Keep air conditioning drip pans clean and the
drain lines unobstructed and flowing properly.
- Keep indoor humidity low. If possible, keep
indoor humidity below 60 percent (ideally between
30 and 50 percent) relative humidity. Relative
humidity can be measured with a moisture or
humidity meter, a small, inexpensive ($10-$50)
instrument available at many hardware stores.
- If you see condensation or moisture collecting
on windows, walls or pipes ACT QUICKLY to dry the
wet surface and reduce the moisture/water source.
Condensation can be a sign of high humidity.
Actions that will help to reduce humidity
- Vent appliances that produce moisture, such as
clothes dryers, stoves, and kerosene heaters to
the outside where possible. (Combustion appliances
such as stoves and kerosene heaters produce water
vapor and will increase the humidity unless vented
to the outside.)
- Use air conditioners and/or de-humidifiers
- Run the bathroom fan or open the window when
showering. Use exhaust fans or open windows
whenever cooking, running the dishwasher or
Actions that will help prevent condensation
- Reduce the humidity (see above).
- Increase ventilation or air movement by
opening doors and/or windows, when practical. Use
fans as needed.
- Cover cold surfaces, such as cold water pipes,
- Increase air temperature.
