• Inspect the inside of the home thoroughly for any visual areas that could indicate a breach for moisture buildup such as all faucets, toilets, and under sinks. Look at windows and doors for tight seals as well as any watermarks on ceilings or floors.  If you smell anything that indicates a musty smell or see air fresheners, it may be hiding a potential problem.


  • Remember mold loves moisture! Check drainage around the outside making sure there is no pooling or standing water and area is free from runoff from higher ground. If a neighbor’s home is draining toward your property that may not be a good sign.  Checking the slope near the foundation making sure to grade slope away will ensure that over time your foundation is safe from water entry.  The roof design and grade are also important to check for areas that may run near walls of the structure.


  • It is a good idea to check that gutters and downspouts have long extensions and not sitting close to the structure. This will help to funnel the water away and not to induce the entry of moisture to the home.


  • It is important to have large roof overhangs to prevent drainage into the walls of the structure. Think of it as a type of umbrella to push the rain outward and away.


  • If you are buying a new home, make sure the ducts are clean and clear of debris. Check with the contractor that drywall was installed without the HVAC system running as it could become contaminated with silica dust from the drywall allowing it to come into the home.  Silica will adversely affect indoor air quality and cause future health concerns.  Ducts should be cleaned generally every eight to ten years as they collect dust that allows an environment for mold to grow.


  • Make sure all bathrooms have exhaust fans for proper ventilation to help prevent moisture buildup and mold growth. A good rule of thumb is to run for 30 minutes after showering or bathing.  A particularly important factor is to check the route of all bathrooms, kitchen, and dryer exhaust fans making sure they are not installed next to intake vents.  If they are, the moist warm air will follow, and soon mold will be found growing in the attic, basement, or crawl space.
