Friendly, showed up on time, and did the work well. It was an old tub drain pipe that had a hole in it under the house. They replaced the pipes at the intersection and tested it afterwards. I inspected the work and it was done well.

He was thorough; but there may be a slow leak in the lines inside the walls. We didn't want to run a full test at that point; as it took 5 years for the coolant to leak out. We'll test again in 6 months. <br />

Percolation Tests questions, answered by experts

Asbestos testing is conducted by collecting samples from materials suspected to contain asbestos and analyzing them in laboratories for confirmed presence.

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.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Epoxying over asbestos tiles is generally considered a safe option when done correctly. Epoxy acts as a sealant, encapsulating the asbestos tiles and preventing the release of asbestos fibers into the air. The key is ensuring that the asbestos tiles are in good condition, firmly adhered to the substrate, and not damaged or deteriorating. This method is only appropriate for tiles that are undamaged and securely in place. If the asbestos tiles are already loose, damaged, or deteriorating, encapsulating them with epoxy may not be a sufficient solution, as it might not address the potential for ongoing asbestos exposure.
