Percolation Tests questions, answered by experts

Knob and tube wiring is an older type of electrical wiring that's no longer used and generally not considered safe. However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

Although the use of asbestos has declined since the 1980s, it remains in several different types of building construction materials for insulation and as a fire retardant. Typically, asbestos can be found in materials such as ceiling and floor tiles, heat-resistant fabrics and coatings, and roof shingles. You may also find asbestos in textured paint and patching compounds.

No, not all popcorn ceilings have asbestos, but a vast majority do. The Environmental Protection Agency (EPA) banned its use in 1973, although it still may have been used up through the early ‘90s. But, in general, homes built or remodeled before the early ‘80s likely utilized materials with asbestos. That being said, a professional test is the only way to determine for sure.

It is strongly advised not to touch or disturb asbestos-containing materials unless necessary. Asbestos fibers can be released into the air when the material is damaged or disturbed, posing serious health risks if inhaled. It is best to leave any handling of asbestos to trained professionals who can remove the asbestos safely.

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.
