I had a water leak in my office bathroom and I called Homquest. They came and assessed the damage and guided me on how to mitigate the mold. I have allergies so I needed to make sure there were no mold spores circulating the air. I would recommend them for mold testing!

Percolation Tests questions, answered by experts

According to the National Cancer Institute, asbestos-related diseases can take anywhere from 10 to 40 years for symptoms to appear. The health risks increase with prolonged and heavier exposure. Risk factors also include:

Amount of exposure
Chemical makeup, size, and shape of the asbestos fibers
Length of time a person is exposed to asbestos
Genetic factors
Source of exposure (direct exposure or secondhand exposure from someone directly exposed)

Unlike some home problems, such as water damage or pest infestations, asbestos can be very difficult to spot. Asbestos is a mineral in the form of microscopic fibers and was previously used in building materials for its bonding and fireproofing abilities. Insulation, roof shingles, ceiling tiles, floor tiles, pipe wrappings, soundproofing materials, and textured paint features like popcorn ceilings are common sources of asbestos, particularly in homes built before 1980.

Age is perhaps the biggest indicator of asbestos, as legislation passed in the 1970s labeled asbestos as dangerous and regulated its use in building materials. Signs of age in the form of wear and tear or material degradation are also indicators that asbestos fibers may be leaking into the air, but ultimately, it’s difficult to detect with the naked eye. If you have reason to suspect asbestos in your home, it’s best to hire a certified asbestos inspector.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Homes built before the 1990s may contain asbestos, but the only way to be sure is to have your home tested. Hire an asbestos testing and removal service to determine whether you have the hazardous material in your home and the best process for removing or sealing it.

While it's possible to cover asbestos tile with carpet, it's not recommended. Encapsulating tile beneath carpet doesn't eliminate the health risks. Over time, the asbestos tiles could degrade, releasing fibers into the air and potentially contaminating the carpet. Disturbance during carpet installation or removal might also release fibers.
