What is  



Asbestos is a naturally occurring mineral fiber. It's a rock.

There are essentially 6 types of Asbestos, only 3 of which were used commercially. These are:

  • Chrysotile or White Asbestos. The most common type in the U.S. , mined in Canada and previously mined in California. It is a serpentine structure, both wavy and hollow.

  • Amosite or Red-Brown Asbestos. The name is derived from Asbestos Mines Of South Africa, it's place of origin. It is an amphibole structure, long straight solid rods.

  • Crocidolite or Blue Asbestos. Only about 2% to 3% of the asbestos we encounter in this country is of the Crocidolite type. It is an amphibole structure very similar to Amosite, except for color. This mineral is mined in Australia.

"I needed some tiles from my kitchen tested for asbestos. I had some samples and did not feel like hassling with mailing them. I found these guys by dinking around on the web. I called and was able to deliver the samples directly. They were very patient with me."



I was very impressed with the high quality of HMA's asbestos inspection and follow-up report. The report provided my family with important information that we needed. We really appreciated Scott Compton's expertise. I highly recommend HMA's asbestos inspection services.

why inspect

If there were more stars, Scott Compton at HMA would get them. We were referred to him by a highly respected building inspector for mold issues. Mold is such a hot and panic-inducing issue and Scott patiently explained to me that of the 1.5 million species of mold spores, only 6-7 are toxic (although the others can be allergans). I was struck by the high level of integrity and professionalism at HMA and Scott doesn't try to sell you on his services.
