Water heater broke called the next morning. They were there that afternoon and replaced it in 1 day. Happy wife happy life. Saved a lot of money on Tylenol.

The technician from Cape Cod Mechanical, Robert, was friendly, efficient, and very knowledgeable. He has come for service twice, to tune up my heating system, and to service my air conditioning.

Great place, great work and great prices. Had another plumbing company start a job and do very poor work. Cape Cod Mechanical came in and Sean fixed my problem in under an hour.
