Indoor Inspection

Basement / Crawl space

Inspect ceiling, joists, and stairs for mold growth

Check the indoor humidity levels with a moisture meter or humidistat. If over 50%, you should consider using a dehumidifier. If you have a dehumidifier, be sure to empty and clean the drip pan regularly.

Look for peeling paint, imperfections, and discoloration as this may indicate moisture. If present, locate the source of moisture, eliminate it, and dry the area within 24-48 hours.

Inspect the floor for foundation cracks. Keep in mind that they may lead to the exterior, so check inside and outside.

Check that the sump pump is functioning properly and the floor drain is intact. (A sump pump is found in some basements or crawl spaces, and it is used to pump water away from the house.)

Inspect your crawl space for moisture leaks and ensure that it is properly sealed. At a minimum, there should be a 6-8 mil. plastic, or vapor barrier, covering the soil.

Exterior / Yard

Make sure all gutters and downspouts are intact, free of debris, and that they direct water away from the house. The downspouts should extend 6-10 feet from the foundation.

Check for signs of water pooling on the roof or around the foundation. If present, this indicates that water is not properly draining from the roof.

Check the slope and grade of the house to ensure that the ground slopes away from the house. The slope should be about 6 inches over 6-10 feet. The slope helps direct the water away from the foundation.

Inspect the siding and exterior paint for peeling, chipping, or bubbling paint. Also look for visible signs of mold growing on the house.

Inspect the roof for missing or curling shingles that could lead to indoor leaks. You may need to hire a professional to inspect the roof.

Check that the flashing around doors, windows, joints, etc., is in good condition. (Flashing is a type of material like aluminum or steel, used around joints on roofs and walls to prevent water seeping in.)

Make sure the outside dryer vent is not blocked or filled with debris.

Make sure the lawn/outdoor sprinklers only spray water onto grass and not the house.

Check to see that any plantings around your foundation are not overwatered. If you have too many plants around the foundation, you may need to remove them.

Floors, Ceilings, Windows, & Walls

Inspect ceilings and walls for any discoloration, sagging, bowing, or wet spots. If you have a dropped ceiling, lift up the tiles and inspect the cavity

Check for condensation, or moisture, on the windows or walls. Condensation may be a sign of high indoor humidity

Look for moisture leaks or peeling drywall around window frames.

If concerned about mold beneath carpet, lift a corner of the carpet and inspect the underside for visible mold.

If you have vinyl wallpaper, look behind it for mold.

If you have mold in your closet, it may be caused by poor ventilation. You will need to increase the air flow, which can be done by leaving the door open. Also, if the closet is full, remove about 1/3 of the contents.

Kitchen & Bathroom

Inspect the caulking, grout, and tiles for damage. Repair as needed.

Check for plumbing leaks around sinks, tubs, refrigerator, dishwasher, and showers.

Check the exhaust fan suction with a piece of toilet paper. With the fan running, place a single sheet of toilet paper in front of the fan. If the paper stays in place, the fan is working properly.

Check to make sure kitchen and bathroom fans vent to the outside of the house.

Does everyone in the household turn the bathroom fan on when showering or bathing? If there isn’t a fan, then they should open the window.

Check for mold or musty smells in cabinets, drywall, and all wood materials. You may want to hire a professional who will use a moisture meter to check moisture levels.

Clean and empty the refrigerator drip pan.

Attic

Check for moisture damage, leaks, and proper ventilation. Ensure that exhaust ducts direct air to the outside.

Make sure the soffits on the underside of the eaves, or overhang, of your roof are not blocked. These provide ventilation or air flow in your attic.

Inspect the walls, joists, and insulation for any musty smell or visible mold.

Appliances

If not present, install a water heater drip pan. Empty and clean it regularly

Have your heating and cooling systems serviced by a professional twice a year. Check the coils for visible mold.

Check water heater and washing machine water lines for plumbing leaks.

Make sure your dryer vents to the outside your house.
