David did an excellent job taking samples and testing for asbestos . The results were sent promptly and he was very professional during the whole process. I would recommend him for asbestos testing.
These guys were the cheapest quote we had. They were cheaper because they figured out a novel way to access the attic through the front of the house. This was great because it kept the dust out of the house and made the whole job quicker.
I've since re-insulated, so I've had a chance to look into all of the nooks and crannies, and they really did do a thorough job of getting it all out.
