Mold Inspection/Do-It-Yourself Mold Testing for Residential Customers

Our MOLD inspection is ideal for houses, condos and apartment buildings, if the occupants experience chronic symptoms or if unusual odors are present. Recurring sinus infections, asthma, chronic fatigue, headaches, scratchy throat, mental fog, skin rashes etc. have been linked to mold or damp spaces. Sensitive individuals, those with Multiple Chemical Sensitivity, mold allergies, Lyme Disease, Auto-Immune disease or those who are generally concerned about how mold may affect their health may benefit from a Mold Inspection.

What Happens During a Mold Investigation?

This process involves scanning walls and ceilings with an infrared camera, conducting a walk-through of the home with special attention to areas around plumbing or water appliances (dishwasher, fridge ice maker, showers, vanities, laundry, etc.), an interview with the occupants, and a series of tests to identify the presence and types of molds. Windows and doors should be kept closed for at least 24 hours prior to the beginning of the survey.

With specialized equipment, we will scan walls and suspect areas for damp spots, temperature differentials and particle counts which may hint to potential mold growth. Visual and olfactory observations are also used to detect problem areas. We then use sampling equipment to collect samples of air or dust throughout the home.

If a carpeted area is suspect, we may take samples of the carpet dust or if the IR Camera indicates a suspicious spot, we may sample the air inside a wall cavity (this requires drilling a small ¼” hole in the bottom of the wall, behind the baseboard).

Samples are sent to the lab for microscopic evaluations (2-3 days) or cultured in our office and analyzed with a microscope to identify mold species (7-10 days). The Mold Inspection service includes a follow-up phone consultation to discuss results and suggested remediation efforts when necessary. Written reports requested for litigation or other official purposes may incur an additional charge.

Examples of areas we may test if applicable:

  • Underneath kitchen sink base cabinet (behind the toe kick)
  • Behind dishwasher
  • Underneath the bathroom vanity shelf (behind the toe-kick)
  • Supply vent ducts in bedroom, home office, etc
  • Inside furnace/air conditioning
  • Wall cavities below leaky windows
  • Under refrigerator
  • Inside furnace mounted humidifier
  • On dehumidifier filter or coil
  • Air cleaner carbon filter
  • Bedding, especially the mattress
  • Upholstered furniture
  • Underneath carpeting, especially if pet accidents occurred
  • On floor joists in basements and crawlspaces
  • Between fiberglass insulation and vapor barriers in walls
  • Behind baseboards in damp areas (Laundry room, bathrooms, basement)
  • On fridge door gaskets or washer gaskets
  • In corners of damp or crowded closets
  • In attics: in insulation, rafters, sheathing
  • Underneath basement stairs

Contact us and we will get you started with testing your home or office.

There are many places for mold to hide and for some individuals with the HLA-DR gene or folks with Lyme Disease, just a bit of mold can greatly affect them. After testing thousands of homes, Martine Davis at IET, Inc. has developed a checklist of specific areas that should be tested if you suspect mold is making you ill.

Mold Inspection Under A Microscope

Here’s a list of locations in your home that should be tested for mold:

  • Underneath kitchen sink base cabinet (behind the toe kick)
  • Behind dishwasher
  • Underneath the bathroom vanity shelf (behind the toe-kick)
  • Supply vent duct in bedroom, office, etc
  • Evaporator Coil inside furnace
  • Insulation sound liner inside furnace
  • Wall cavities below leaky windows
  • Under refrigerator
  • Inside furnace mounted humidifier
  • On dehumidifier filter or coil
  • In air cleaner carbon filter
  • On upholstered furniture
  • Underneath carpeting, especially if pet accidents occurred
  • On floor joists in basements and crawlspaces
  • Between fiberglass insulation and vapor barriers in walls
  • Behind baseboards in damp areas (Laundry room, bathrooms, basement)
  • On fridge door gaskets or washing machine gaskets
  • In corners of damp or crowded closets
  • In attics: in insulation, on rafters or sheathing
  • Underneath basement stairs

Air sampling is not helpful if mold is growing in these areas. Most of the time, an air sample (called a spore trap or culture plate) will detect normal mold counts near these contaminated areas. Even ERMI testing (DNA testing) may not detect molds hiding in such areas. There are numerous cases of low ERMI scores in homes where substantial mold contamination exists in the basement, crawlspace, or in wall cavities. So homeowners must be their own investigator and look for mold with a high quality LED flashlight. Any suspicious areas can easily be tested by submitting samples collected with Scotch tape or swabs and mailed to our Wisconsin office. Call 800-MY-AIR-TEST or contact us to get started.
