Percolation Tests questions, answered by experts

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

Typical methods for asbestos removal include encapsulation, enclosure, and complete removal.

DIY kits are available, but professional testing ensures accurate results and compliance with regulations.

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.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.
