Jim was very friendly, experienced, and professional. From the time I submitted the request to when he was able to come test my tile and share the results, less than 36 hours had past. Very impressed with HomeAdvisor and North Central Inspection Service. Highly recommend them for any Asbestos...

Arrived on time. Quality of work seems fine, though the true test will be time. The price seemed high and the technician struggled to explain/justify the costs. Technician suffered from women-who-ask-questions-annoy-me syndrome. Not a terrible experience, but left a bad taste in my mouth.

Very professional and knowledgeable. Took the time to listen to me about the problems, performed a diagnosis and told me what to expect with each test. I would definitely call for another appliance repair.

Percolation Tests FAQs, answered by experts

While it's possible to cover asbestos tile with carpet, it's not recommended. Encapsulating tile beneath carpet doesn't eliminate the health risks. Over time, the asbestos tiles could degrade, releasing fibers into the air and potentially contaminating the carpet. Disturbance during carpet installation or removal might also release fibers.

Unfortunately, asbestos is not easily identified and can often be hidden in plain sight in your home. While it can look like fluffy fibers, tiny pieces can also appear in materials like plastic or cement, making it impossible to identify on your own properly.

Plus, since asbestos is so dangerous when disturbed, you should never root around to try and find it. This job is best for a professional who can test for the material properly.

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.

Asbestos testing is conducted by collecting samples from materials suspected to contain asbestos and analyzing them in laboratories for confirmed presence.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.
