"I live on the San Francisco peninsula area. My kitchen floor needs replacing and before the floor installer could begin, they informed me I needed my existing flooring needed to be tested for ASBESTOS before any work could be done. I reached out to multiple companies from different platforms for ASBESTOS TESTING and not one company replied back to me except for ADVIRO recommended from ANGI"S LIST. Response was quick and professional. They made initial contact the next business day via text message, email and phone call. An appointment was made, 2 techs came to do the testing, less than an 20 min visit and result were emailed within 2 days. Original price quote was $455 but ended up being $535, due to a second layer of flooring. Each layer needed to be tested. They also recommended the vinyl border trim for testing, (again an additional cost) that I kindly declined. I would highly recommend ADVIRO."

"I had recently had my home inspected and was concerned about mold and what to do about it. I called Mr Standish because I had just used him for my home inspection, and he was again able to do the mold testing right away, and got back the results to me within a few days. It was helpful to have him answer questions about the test results, and the problem was minor, and something that did not require any major work(thank goodness!)Mr Standish is very knowledgeable about his work, and is honest, which I truely appreciate."

"We had several issues that caused us to contact a company that can come over and check our house for any problem that can be solved and reduced our utilities bills. We contact this company and we asked them to come over and see what they can do. Avi came over and explained to us how they work and what they do in order to determine what can be done. The initial work included sealing all the openings in the house and then they made some tests with special machine that made a clear picture that our air conditioning system have some leaks that causing the system to work extra time. After they completed the testing, Avi came over with another crew of workers and fixed the ducts making sure that there will be no more leaks from that area. The work that they did was good because they made a massive testing before they came to the conclusion about the air conditioning ducts.

"Smart Builders was very helpful in scheduling and working around other workers who were at the house.  The crew was very professional and efficient in its work, and we were completely comfortable in leaving them to do the job while we were gone.
Also, Smart Builders uses a foam product that is optimal for as a fire barrier, and that does not have any odor 24 hours after application.  We are very happy with the work that Smart Builders did.

FAQs for asbestos testing projects in Knightsen, CA

Asbestos appears as long, thin, or curled mineral fibers that are not visible to the naked eye under normal conditions. Homes constructed before 1989 are more likely to contain this material, so a professional inspection is essential. Because asbestos identification requires specialized techniques, having a certified inspector assess your property is the safest way to confirm its presence and protect your family’s health.

Free asbestos testing services do not exist. You can purchase testing kits online for $30 per unit, and these kits include lab fees, return shipping, consultation, sampling media, and the final results. The results from a kit are less detailed and accurate than those provided by a certified asbestos testing professional. Since collecting a sample exposes you to harmful fibers, hiring a professional is essential to ensure safety and accurate testing.

Receiving asbestos test results takes one to seven days, but different labs offer varying turnaround times. When expedited processing is arranged, the laboratory completes analysis within 24 hours; standard processing requires up to two weeks. Hiring a certified professional ensures that all samples are collected correctly and results are provided without delay, safeguarding your home throughout the process.

Home insurance doesn't often cover asbestos testing and removal. Many policies have a clause called a "pollution exclusion," which means they do not cover indoor pollutants like asbestos. However, your insurance company might cover something like asbestos siding removal costs if it is released due to things beyond your control, such as storm damage.

If a DIY project or accident in your home releases harmful fibers, you must pay for the test and removal.

Yes, you can legally inspect and remove asbestos in your house as long as it's a single-family home and not a multi-family unit. However, the EPA strongly recommends hiring an asbestos abatement pro since testing can be dangerous.

Pros have all the right tools and safety equipment, and you risk breathing in the fibers by taking samples yourself. They also know how to collect samples and safely dispose of materials properly.

Asbestos encapsulation is a process that seals asbestos-containing materials with a protective barrier to prevent the release of harmful fibers. It serves as an alternative to complete removal when full abatement is not necessary. Encapsulation costs between $2 and $6 per square foot, offering a cost-effective option that contains asbestos safely when applied by a certified professional.
