How To Prevent Mold
In The Home


Let’s talk about how to prevent mold for a moment. You’ve probably heard a lot about the risks of toxic household mold and about the costs of mold removal, but mold prevention is a topic discussed less frequently. If you know how to prevent the growth of mold, however, and take some relatively simple steps to prevent future problems, you can save yourself a lot of money and aggravation. After all, mold removal is costly, time consuming, and difficult!

The Importance of Mold Prevention

Household mold can contribute to numerous health problems, including respiratory difficulties such as asthma and pneumonia, rashes, depression, fatigue, digestive problems, and inflammation and pain in the joints. Mold can also literally eat away at the structures of the home, causing extensive damage. It’s extremely important to prevent the growth of mold in the home because most removal is a difficult and costly procedure. It’s easier to prevent mold in the first place than to remove it later. 

How to Prevent Mold

The key to preventing mold is moisture control. Without excessive moisture in your home, mold cannot grow. Experts generally advise keeping the humidity levels in your home below 55%. You can use a hygrometer to monitor your humidity levels.

Give your home a thorough checkup to identify any issues that might contribute to future mold growth. Correct any problems as soon as possible. If you’re not sure how to make the necessary repairs, hire a professional to assist you. It will be well worth the cost because you’ll save so much money in health care, home repair, and mold removal expenses down the road.

  • Window frames – check around all window frames to make sure they seal tightly and no water seeps in.
  • Sinks, toilets, and tubs – check under and around all sinks, toilets, and tubs for any leaking water. Install water leak sensors in these areas to alert you early to any leaks.
  • Hot water heaters – check around your hot water heater for any leaking water. This is another good place to install a water leak sensor.
  • Roofs – examine your ceilings for signs of a leaky roof. Sometimes you can’t see signs of leakage from inside the house, though, until the problem has gotten pretty bad. If you’re not sure how to inspect your roof, hire a professional to get up on the roof and inspect it for you. Here is more information on how to deal with a ceiling water leak.
  • Bathrooms – check for adequate ventilation, especially when showering. If the room gets really steamy when you shower, turn on an exhaust fan or open a window a little. If you don’t have an exhaust fan in the bathroom, you may need to install one. Here is more information on preventing bathroom mold.
  • Basement – try the sniff test. Is there a musty odor in the basement?  If so, there may be mold present. If the basement feels or smells damp or musty, purchase a dehumidifier.
  • Attic – try the sniff test in the attic, too. If there have been any leaks in your roof, there may be mold in the attic. (See picture below) If not, keep a hygrometer in your attic to measure humidity levels. One hygrometer that is made by Ambient Weather comes with a portable sensor that you can keep in your attic. It transmits the humidity level to the main unit so you can monitor your attic humidity levels very easily.

In addition, you can prevent mold by:

  • Wiping up any water spills as soon as possible
  • Using a fan to help dry any damp carpet as soon as possible
  • Keeping windows tightly closed when it’s raining outside
  • Using exhaust fans in the bathroom when showering and in the kitchen when cooking
  • Wiping showers, shower curtains, tubs, etc. dry with a towel after use
  • Keeping an eye out for signs of mold and addressing any problems promptly
  • Installing a solar fan in your attic so that you have good air circulation there all year round.
