Percolation Tests FAQs, 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.

According to the National Cancer Institute, asbestos-related diseases can take anywhere from 10 to 40 years for symptoms to appear. The health risks increase with prolonged and heavier exposure. Risk factors also include:

  • Amount of exposure

  • Chemical makeup, size, and shape of the asbestos fibers

  • Length of time a person is exposed to asbestos

  • Genetic factors 

  • Source of exposure (direct exposure or secondhand exposure from someone directly exposed)

Depending on the size of your home, the inspection process could take a few hours or a few days. While inspecting your home, the asbestos specialist will take small sections of the potentially contaminated material. They will then send the sample to an accredited laboratory or the local health department for testing. 

The cost of asbestos testing depends on your location, the home's size, and the testing area's complexity. Plan to spend between $230 and $800 for testing. During testing and while handling potential asbestos, the specialist may wear protective gear, including gloves, overalls, appropriate footwear, and respiratory equipment.

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

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.
