I am very grateful to DeMarco for fixing gas leak at my landlady's house. We called several companies. Only one came, but was not able to fix it. I called DeMarco next morning. Mohammed came to rescue us. He fixed the gas leak, checked our furnace for free, pushed back washing machine in the hall. If it was not DeMarco, we would still have no heat and no hot water. I highly recommend them !

Adrian service was excellent
