They were hired to investigate a leak in the pool. The rep said he did not have the proper equipment to do a pressure test and would let me know when he could get it. He did not call and my subsequent call to the company was not returned. There was no charge.

So far so good. The real test will be the next long hard rain, which we haven't had since the repair. Was a little sloppy applying the epoxy to the wall.

Percolation Tests questions, answered by experts

If you suspect exposure to asbestos, prioritize seeking medical advice by informing your healthcare provider about the potential exposure with clear details about the circumstances that led to the exposure. Regular health check-ups and screenings if you work in high-risk industries or live in a home with asbestos are essential for early detection of any asbestos-related conditions. You should also consider consulting occupational health experts or legal professionals for guidance on potential next steps and preventive measures.

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.

Asbestos was commonly used in cloth wiring, but not all types of cloth wiring contain it. The age, condition, and appearance of the wiring can provide clues as to whether asbestos is present or not, but the only way to know for sure if the wiring has asbestos is to have it tested.

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.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.
