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.

Asbestos testing takes place in two stages—collection and lab testing. Collection can take less than 20 minutes if a professional manages to get a direct sample. If air samples are required, then the pro will set up a testing device and return to collect it. In both cases, the sample is sent to a lab and results are confirmed or denied usually within one to two days.

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.

Yes, even a single, one-time exposure to asbestos can be harmful and increase the risk of future illness, including certain diseases and cancers. The level of risk depends on several factors, such as the concentration and intensity of the exposure. A small, brief exposure is less likely to cause significant damage than an exposure to a high concentration of asbestos fibers.

The likelihood of developing severe health issues increases with repeated or prolonged exposure. Individual reactions to asbestos vary; some people may have multiple exposures without harm, while others are more susceptible. Asbestos-related illnesses may not manifest for 10 to 40 years after inhalation.

Due to these risks, it is crucial to take precautions. Personal protective equipment (PPE) may not offer complete protection, as fibers can get through small gaps. The EPA recommends hiring a professional for testing and removal if you suspect the presence of asbestos in your home. If you are concerned about a potential exposure, consult your doctor.
