Dave was super helpful and steered me toward the real solution I needed -- not testing but direct remediation of a leaking window and wall. His experience really helped get the job done and to calm my nerves after I discovered the leak!

I looked around for mold testing help for a few days; I threw all of my belongings out according to recommendations online. When Carl arrived, he put my worries to rest and I am so very glad I will have the right test in hand in just a few days. I feel like a huge weight is off of my shoulders....

I wasn't on hand to actually evaluate workmanship. Water leak was the reason we called and although they might have finished the job without actually doing a water test, I asked them to do one and they came back and did it. No leaks. Very easy to communicate with, and very responsive!

Percolation Tests FAQs, answered by experts

Professional asbestos testers or environmental consultants are the best people to call to test for asbestos. An asbestos testing company specializes in collecting and analyzing samples and will be the most qualified to do the job for you. An environmental consultant may not specialize in handling asbestos, but should still have the knowledge and know-how to safely collect a sample and send it off for analysis.

Testing is crucial to identify harmful asbestos fibers common in building materials from older properties, ensuring safe environments and health.

Unlike some home problems, such as water damage or pest infestations, asbestos can be very difficult to spot. Asbestos is a mineral in the form of microscopic fibers and was previously used in building materials for its bonding and fireproofing abilities. Insulation, roof shingles, ceiling tiles, floor tiles, pipe wrappings, soundproofing materials, and textured paint features like popcorn ceilings are common sources of asbestos, particularly in homes built before 1980.

Age is perhaps the biggest indicator of asbestos, as legislation passed in the 1970s labeled asbestos as dangerous and regulated its use in building materials. Signs of age in the form of wear and tear or material degradation are also indicators that asbestos fibers may be leaking into the air, but ultimately, it’s difficult to detect with the naked eye. If you have reason to suspect asbestos in your home, it’s best to hire a certified asbestos inspector.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

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.
