This was a test cleaning to determine whether to continue using service. The cleaning covered two bathrooms kitchen and dining area. Work took one hour and twenty minutes. Cleaning was fine but outrageous fee of $280 dollars for such a short time.

Percolation Tests questions, answered by experts

Through air sampling devices and surface swabs in key areas of concern.

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.

Because of the danger of inhaling asbestos fibers, figuring out through testing whether your popcorn ceiling contains asbestos is definitely worth it. If the popcorn ceiling texture has asbestos, remove it as soon as possible to keep your family safe. Any home built in or before the 1980s that has popcorn ceilings could have asbestos, necessitating testing. Asbestos carries several health risks for people who inhale it, including the increased chance of developing lung cancer in the future.

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.

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.
