Armando was knowledgeable and thorough. The final test will be to see if the termites return in 6 mow to a year. Service seemed comprehensive and tidy.

Percolation Tests questions, answered by experts

If you think you’ve touched asbestos, do not put on a mask. This is important because you may take the asbestos fibers on your hands on trap them in the mask. Make your way to a sink and wash your hands thoroughly. Remove any clothes and seal them in a bag, then take a shower. Call your doctor and let them know you’ve been exposed to asbestos, and make sure you see them as soon as possible. The reason you keep the clothes is in case anyone wants to confirm the presence of asbestos.

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.

Unfortunately, home inspections do not check for asbestos because of the liability factor involved. That’s why you should hire a trained professional with specialized equipment to test for it.

They will inspect all areas of the home and take samples of various materials to test. Opting for an asbestos inspection can prevent the risk of exposure to this hazardous material and save on costly repairs that may be required.

There are products that still contain asbestos, but they were typically installed decades ago. Common places where you may still find asbestos-containing materials are in siding, wrapped around ductwork, in older appliances (i.e., stove and gravity furnaces), and in floors. Asbestos was primarily used as an insulator, so anywhere in an older home where you lose heat is where you will most likely find asbestos.

Often found in old insulation, tiles, and roofing materials in pre-1980s buildings.
