"Two Heritage plumbers replaced a leaking silcock that was long in need of replacement at our home in Methuen, MA. The two plumbers did a great job, were very professional and had a great sense of humor. Very happy with the quality of work. Ted"

"We had MA Design and Construction completely renovate our kitchen last year and our master bath this year and we couldn’t be more pleased. We really appreciated their design input, which helped us with materials selections, color schemes and all manner of details that we never would have considered on own. The contractors were very attentive to the fit-up, since our 120-something year old house has few square corners or flat floors, but the final products hid those oddities very well. We were very happy with all the specialists who came to our house. Always punctual, courteous and friendly. Our dog will miss them. We are planning to have MA Design and Construction renovate another bathroom in the fall."

"George was wonderful to work with in the planning phase, very responsive, he answered all my questions as we discussed the install. I sent him photos of where the system would go and and he confirmed it would be a good fit. He arrived promptly on the install day, along with Dave who was also great, and they put in the system. About a half hour after they left, I discovered a leak from a small copper pipe and called George. He came right back to fix it which he did, but we realized it was not his work. Someone else had put in that section of copper tubing incorrectly. George was very kind and accommodating and fixed the problem. He and Dave were a pleasure and I really appreciated it and I would absolutely hire them again."
