I used them to video my under slab pipes. Two needed replaced. When they were under the house they found a third one needing replacement. In all I had three changes they priced after the work started. The additional prices they gave me were fair. After reviewing the photos taken of the repairs I was concerned about the water lines and asked for a price to replace them. He convinced me it was work that did not have to be done. He could have easily taken the work but instead saved me money. The crews were professional, stayed until the work was completed, and left the site clean. I would definitely use them again.
