Preventing Mold and Mildew Growth in the Home

Updated: Aug 2, 2018

Every home has the potential to harbor mold and mildew. The air all around us is filled with mold spores thriving and growing in moist environments. It's not realistic to think that we can keep mold spores from entering residential buildings. The challenge is to keep them from thriving and growing. 

The main way to prevent the growth and reproduction of mold in the home is through prevention of leaks and condensation, and the proper installation of mechanical ventilation. Mildew, also called mold, can't grow unless it has moisture, so let's find the areas in our homes where the moisture is and dry it out!

Use Bathroom Ventilation

There are multiple places to be aware of in the home that can create moisture problems and therefore mold. Showers produce a prodigious amount of water vapor through spray and steam. You must act to dry out a room that's been showered in and prevent the moisture from entering other parts of the home as well. Mechanical ventilation used before, during and after shower use is the best way to remove this moisture. Quickly drying the room will help prevent mildew from forming in corners, cabinets and drawers.

Fix Leaky Faucets and Pipes

Fixing leaking pipes and cleaning up any water dripping from them right away will prevent damage in the form of mildew and the bad odors and ugly stains associated with the damage.

Use the Rage Hood and Cover  Cooking Pots

In the kitchen install a range hood with outdoor ventilation. Range hoods are not only for removing smoke and cooking odors but also for removing excess moisture from boiling liquids.

Water From Outside Coming In?

Water leaks from outdoors can cause serious and expensive damage to a home. Inspecting the roof for leaks,checking the flashing to be sure all is in good repair and sealing any suspicious spots can save prevent mold issues and untold future damage. Be sure gutters are clean and downspouts are guiding water at least three to six feet from the home.

Condensation in the Closets?

Even closets need to be monitored for condensation and mildew problems. In the humid season, if closets are against an outside wall it's best to leave doors open, install louvered doors or use a non-toxic chemical dehumidifier to help absorb excess moisture and prevent condensation.
