I was contacted by Scott very promptly and was able to make an appointment within days. Scott did a thorough investigation but did not find any mold in my home even though I tested positive for a Gliotoxin Derivative. I wish he could have also offered a test for possible mold in the air.

Percolation Tests questions, answered by experts

Older textures may contain asbestos, requiring careful handling and professional inspection before work begins to ensure safety compliance.

Professional testing is advisable to ensure safety regulations are met, and accurate results are obtained using certified methods.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.
