They were referred by the plumber. Had no chance to check them out, and I really do not have a point of reference/comparison since I have not had this experience. They seem t have done a good job on getting drying out the wall. Not so good a job in clean-up after. Felt almost harassed by their collection guy. Check was sent to me by insurance which required my endorsement; collection guy called me before I even got the check. I mailed it the day after it arrived in the mail.
