Percolation Tests FAQs, answered by experts

No, an N95 mask will not protect against asbestos and many other hazardous materials, such as carbon monoxide, gas, chemical vapors, and other gases. You will need a respirator specifically designed to protect against asbestos. However, if you suspect asbestos is present in your home, hire an asbestos abatement professional immediately and avoid the area until they arrive for the inspection.

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

It can be safe to live in a house with asbestos as long as the asbestos-containing materials are intact, in good condition, and not disturbed. Asbestos becomes dangerous only when its fibers are released into the air, which happens if the material is damaged, crumbling, or disturbed during renovation work. If you suspect asbestos is present, do not disturb it. Instead of removal, materials in good condition can sometimes be encapsulated. It is recommended to have regular professional inspections to monitor the condition of the asbestos and prevent health risks from potential exposure.

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.

Unfortunately, home inspections do not check for asbestos because of the liability factor involved. That’s why you should hire a trained professional with specialized equipment to test for it. 

They will inspect all areas of the home and take samples of various materials to test. Opting for an asbestos inspection can prevent the risk of exposure to this hazardous material and save on costly repairs that may be required.
