After receiving the test results, and finding out the basement had mold, I hired Alexander and Associates to complete the job. It was a very thorough and professional job, and I am extremely happy with the results and the total experience. I would highly recommend this company!

A1 Certified was professional and courteous for starters. They were on time, and shared valuable information about mold/mold abatement. Testing results were needed prior to the time frame and the gentleman that did our testing, called the lab and rushed the results.

Done in one day, at a reasonable cost. A test of efficiency is performed afterward by a separate company, and the tester said they did a quality job. We are very, very happy with the result.

My 1945 toilet was "running"; when I opened the tank, I discovered that the water valve was continuously spraying a small mist. I know homeowners can repair this relatively minor problem, but I am elderly and my husband had been working a 9 day shift. I decided to call a plumber to save him...

Percolation Tests FAQs, 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.

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)

Asbestos is absolutely cancerous. In fact, around 4% of all lung cancer cases are the result of asbestos exposure. This is why we recommend a full, professional removal and cleaning of any asbestos found in your home. If you are unsure whether there is any present, you should call a pro who will inspect your property.

Costs depend on the number of samples, property size, and lab processing fees.

No, you do not have to worry about new popcorn ceilings having asbestos. All residential building materials used since the mid-1980s stopped including asbestos, so new popcorn ceilings have no risk of asbestos. You can still create a textured drywall ceiling with a popcorn texture if you like, but new techniques have no risk of adding asbestos.
