IAQ and Mold Inspections

Indoor Air Quality is fast becoming a serious concern for the following reasons:

  • Homes are built increasingly tighter in recent years, this translates to less to no fresh air “breathing of the home” and subsequent creation and trapping of water vapor, aka condensation.  This is a conducive condition to mold growth.

  • Newer construction techniques and products generally have higher chemical contents, causing irritations for inhabitants; leading to possible health effects, both short and long term.

  • Deficiencies in systems cause contaminated, unfiltered air to enter the breathable air stream.

  • Air and water intrusion issues are conducive conditions for mold growth inside a home or building.

  • Improperly tuned gas appliances are a major source of harmful gas by-products due to improper gas combustion.

Mold Inspections
Covenant Inspections/Randy Ryden is licensed by the Tx Dept. of Health to perform Mold Inspections — MAT1183

  1. Apparent mold growth present (lab analysis required to confirm).

    • Only a swab or tape lift sample is required for each affect area, color, type of growth and type of substrate (to the discretion of the inspector).

    • Air sampling may be recommended if a professional IAQ equipment pre-test return high results in the mold spore ranges.

    • Air sampling may be desired by the client for good measure for any reason, depending on budget constraints.

    • Swab/tape lab fees are $50 per sample; see below for air sampling fees.

  1. No visible growths present. Moldy smells are present. Known water leaks/intrusion.

    • In this situation, air sampling is generally the only manner to determine what type if any mold is present in the home.

    • Air sampling will be performed based on results of professional IAQ equipment pre-testing; this pre-test procedure allows pinpointing the suspect areas, these locations provide the best sampling success.

    • At least one exterior baseline sample is required, ideally 2 are captured for an averaged baseline number for the ambient mold spore count. The lab fee for a single outdoor is $100, for paired samples is $175 (we have negotiated a discounted schedule with the lab to ensure clients opt for a best practice approach).

    • The HVAC will be reviewed at a high level and if the maintenance is deemed to be lacking, an additional air sample with the HVAC running and duct work manipulated will be recommended.

    • All indoor air samples are $100 each.

  1. No visible growths present. Moldy smells present. Unknown water leaks/intrusion.

    • A building science inspection should be performed to determine the source of the issue(s) and the source of any unintended water source (there must be a water source for mold to form). This service is priced on sized of home and starts at $275 plus the lab fees. Call for a quote.

    • In this situation, air sampling is generally the only manner to determine what type if any mold is present in the home.

    • Air sampling will be performed based on results of particle counter and/or mVOC pre-test; this pre-test procedure allows pinpointing the suspect areas, these locations provide the best sampling success.
