Best Commercial Backflow Preventer in Baltimore MD

First class. Chris arrived on time. He was courteous and professional, and he worked diligently to diagnose the gas connection problems in my residence. Chris was also very knowledgeable; his professional insights helped me decide how to resolve one problem that unfortunately could not be fixed. I would use Metcalf again in a heartbeat and will be recommending this business going forward.

Just wanted to say ed and nick were very nice and professional. Very knowledgeable and did quality work.

I have used and recommended this company many times. Always reliable, honest and fair.
