They contacted me promptly, and we made an appt for an estimate. It got delayed a week due to person being exposed to person with COVID. We waited for test results, and he came late the next week. Mold was a small amount to be removed. The workers were masked, polite and finished within an hour.

Percolation Tests questions, answered by experts

While asbestos can’t be directly absorbed through the skin—the fibers are too big—skin contact can still produce symptoms. Contact dermatitis can flare up in sensitive individuals but in most cases, the danger from asbestos comes from inhaling the fibers, or dust, that is produced when asbestos is disturbed. If you touch asbestos by accident, immediately wash yourself and your clothes.

Asbestos was commonly used in cloth wiring, but not all types of cloth wiring contain it. The age, condition, and appearance of the wiring can provide clues as to whether asbestos is present or not, but the only way to know for sure if the wiring has asbestos is to have it tested.

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.

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.
