It was actually mold spore testing. I hired Exceptional Restoration Services (on Angie) who botched a mold remediation job and contaminated my whole house - I am hypersensitive to mold. NextDay Inspect tested the house and quickly provided a very detailed report of their findings - necessary to...

Very honest inspector. When determined no mold, he provided guidelines to remove stains and repair a small leak in the shower. If I need similar testing in the future, I'll definitely call again. Didn't try to make the problem into something it wasn't and didn't insult my intelligence.

After the visual inspection, the technician told me there was definitely mold in the HVAC system and recommended we do the remediation. The cost: $1500. I decided on going ahead with the testing first just to be sure we had mold before spending that much money. The test was simple enough. The...

Percolation Tests questions, answered by experts

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.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

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)

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 has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.
