While our home was under a home warranty, we developed a leak in the hot water line in the concrete slab under the kitchen floor. The home warranty service required us to use a leak detection service, so we called American Leak Detection. They told us someone would be out within a few days and would bring their detection equipment. They did not show up, and days turned into weeks. When we finally were able to get someone to come to our house, we were told their sophisticated detection equipment was being used on another job. The man proceeded to tell us the leak was probably under the kitchen cabinet, which they would have to rip out, and we would have to pay to replace it. I was very upset, because I could tell just by standing on the kitchen floor that there was a warm spot about a foot away from the base of the cabinet. American Leak Detection was just guessing. After pointing this out, he proceeded to jackhammer the floor - there was concrete dust all over my kitchen and dining room! They never offered or suggested that we cover the rooms with plastic, or made any effort to contain the dust. Sure enough, the leak was NOT under the cabinet. I felt American Leak Detection did a poor job and were much less than professional.
