I called them late last week about a tapping in the wall which sounded like a leak, Stacy came out today (Monday) on time and he is extremely pleasant and curtious. Of course, no tapping at all happened (isn't that always the way?). He checked all he could check (w/o opening the wall, which with no tapping, why do it now).
If it returns, I will call them again or if I have any plumming need I will. Every part of my experience was a pleasure.
