They fix problems
Called at 9am and they were at my house within 1 hour. No BS diagnosis charge. Reggie located the problem, offered 2 solutions and prices, brought a horizontal bore machine and replaced my main supply line by 1:30. Another place that I called first wanted $60 just to do a walk through to locate a problem that I already knew where it was. When it came time to pay, I felt comfortable about my decision.
