How to Prevent Mold in your Home

Mold is obviously one thing nobody wants in their home…unfortunately, mold is everywhere.  But there are simple ways to prevent mold from growing out of control.  In this short article, we’ll be looking at some ways you can protect you and your family from seeing that disgusting, not so FUN-gi in your home.

Controlling Moisture

Controlling moisture is one of the best ways to prevent mold growth.  So how can you do that and how does that prevent mold growth?  Well lets dive in and take a look.

  • When leaks or spills happen, make sure and clean them up immediately.  If damp or wet materials are fully dried within 24-48 hours, mold will not typically grow.

  • Keep indoor humidity levels low.  Indoor humidity should be between 30%-50%.  Use a dehumidifier in the basement to maintain those levels. You can get a device at any hardware store that measures Relative Humidity for under $50.00.

  • Use ventilation fans while showering or cooking.  Exhaust fans in the bathroom & kitchen should be clean and vented to the exterior.  After showering or taking a bath, run the fan for at least 30 minutes.  Use your kitchen exhaust fan while cooking or boiling water to remove humid air.

  • Repair any roof damage or leaks.

  • Clean and repair gutters frequently.  Make sure downspout extensions are used and extend at least 6′ from your home.

  • Make sure the ground slopes away from the foundation of your home.  This will help keep water from pooling up and entering your basement or crawlspace.

  • Dry any condensation or moisture you see on windows or pipes.  If pipes are typically “wet” install foam pipe insulation.   When you have a build up of condensation though, you have a high humidity level in that room or level in your home…so decreasing the humidity level is a must.

Mold prevention is an easy task…and can save you thousands of dollars!  

Ventilation is another important step in controlling moisture.  Usually, 6 out of 10 homes that I inspect, the bathroom exhaust is vented into the attic space.  This is a big issue.  This creates a high humidity problem within the attic space.  This affects the insulation, roof decking and the roof trusses.  Mold is always spotted in the attic when the exhaust vent is not vented to the outside.  So remember:

  • Exhaust fans must be vented to the outside
  • Exhaust fans should be located in the kitchen, every bathroom, washer/dryer room.
  • Ductwork connections for the exhaust fans should be sealed.
  • Make sure to use them!

Mold needs food and moisture to grow.   The food source is always going to be there.  But if you remove the moisture part, it’ll have a tough time growing.  Less moisture in the air is better, but some moisture is needed.  Just remember that mold growth can be prevented.  Take steps now to avoid costly repairs later.  

Healthy Living!
