William and his 2-helper crew showed proper awareness, expertise, and speed. His written estimate/contract seemed fair. He told me he estimated 27 man hours; they actually finished the job in 15 man hours, so my cost on a per-hour basis was expensive. Quality of their work was very good, except they disconnected the controls to our drip system, apparently when they were working on the electric dryer. They did not re-connect, but, since it was such a minor thing, I did not call back on it.
