Mold spores are a common contaminant found in indoor air. Most of the mold discovered inside a home originates outdoors.

Exposure to mold is an everyday occurrence for most people. In recent years it has been determined that mold can have potential health effects if the spores are inhaled in large quantities. These include allergic reactions, asthma, and other respiratory problems.

Mold Resources & General Information

If you are concerned about mold in your home, we can help. At H.M. Pitt Labs we can analyze air and surface samples for common airborne contaminants. These include fungus, pollen, fibers, and dust mites. Our analysts and technicians have participated in specialized Indoor Air Quality (IAQ) coursework including those offered by McCrone's Research Institute in Chicago, IL, the American Indoor Air Quality Council/Aerotech Labs in Arizona, and the Indoor Air Quality Association Inc.

For locations in the Southern California region, we are available to perform IAQ site investigations. Our technicians will personally inspect your home for visible signs of mold contamination. They will also perform air quality tests, provide evaluation and interpretation of the results, and if necessary, provide remediation plans.

You can also send surface samples to the lab for analysis. Surface samples can be taken by gently pressing the sticky side of a piece of crystal clear tape to the suspect location. The tape can then be pressed to the inside of a plastic sandwich bag for protection in traveling. Label the outside of the bag with the location of the sample (ie: under kitchen cabinet) and your name and address. All samples submitted to the lab should also include a completed Chain of Custody record (click here to download form).
