I called Greg to replace a 21 year old water heater, located in my attic. He was on a job, but could do my work the next day. He called back in about an hour, and said he was rained out of current job, and could come today at 2 PM. He arrived on time and began the work. His helper arrived an hour later with the new water heater. The hardest part of the job was getting the old heater down from the attic. Greg completed the job in less than three hours, he called me back later the same evening, and wanted to be sure that we had hot water. Great job!
