Asbestos-containing materials are not easily affected by water and do not disintegrate or dissolve when exposed to it. However, porous materials can deteriorate due to water exposure, leading to the release of asbestos fibers into the air. The settling of asbestos fibers can also occur as water makes them heavy, which reduces the risk of airborne exposure, though future disturbance of the materials could cause risk. Wetting asbestos-containing materials does not constitute safe removal, and the proper handling and disposal of asbestos materials should be left to professionals.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

Asbestos can be found in many building materials, especially if the materials were installed more than 20 years ago. Asbestos-containing materials (ACM) can include:

• Acoustic ceiling tiles

• Furnace insulation

• Home appliances

• Fire-retardant clothing

• Cement pipe

• Pipe insulation

• Wall and ceiling insulation

• Vehicle brake pads

• Vinyl flooring

• Sprayed acoustic ceilings

• Stove insulation

• Patching compounds

• Textured paints

• Roofing shingles

• Siding

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.
