We received an estimate from a different plumber for $1,100 for the same work but that didn't pass the sniff test. Moxley Plumbing came out and determined the issue in both bathroom faucets. For one faucet they didn't have the part so they quickly ran out to get it and the total for the work...

Percolation Tests questions, answered by experts

If you hire a dedicated asbestos inspector near you in addition to your local home inspector, it will cost between $200 and $800. If, however, your general home inspector happens to be certified as an asbestos inspector, they can charge you a smaller fee and tack on the cost to the home inspection. In general, home inspectors do not do physical testing, but will provide a visual assessment so you know what you are working with.

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.

It is not recommended to drill into asbestos siding because doing so can release hazardous asbestos fibers into the air. The safest way to handle asbestos-containing materials is to have a professional remove or encapsulate them.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

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.
