Was able to install the new kitchen faucet no problem. Also had the supply lines replaced because the ones installed when the house was built were non-standard. Very professional from start to finish.

Percolation Tests questions, answered by experts

Since the EPA partially banned asbestos in 1989, it is no longer used to manufacture new siding in the United States; production had largely ceased by the early 1980s. Many other countries, such as Canada, Iceland, and Denmark, also have bans on asbestos. However, asbestos siding is still present in many homes built before the late 1980s. The only definitive way to know if your siding contains asbestos is to have it professionally lab-tested.

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.

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.

In the event of suspected or confirmed asbestos contamination on the body, it is imperative to take immediate measures to reduce health risks. To avoid further exposure, carefully remove contaminated clothing and shower thoroughly to remove any asbestos fibers. Seek prompt medical attention, and inform your healthcare professional about your suspected asbestos exposure. Since asbestos-related health issues can take years to surface, regular medical check-ups are advised for anyone with a history of exposure.

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)
