"Removed hot water heater, added tankless heater. unclogged slow drains. Very professional, 3 guys showed up and made quick work of the projects. Walked us through what they were doing, in a professional, easy to understand manner. Gave us final directions on how to use the new tankless heater. Also, informed us on what to look for if our 70 year old pipes start having issues. They did not push us to spend a ton of money to re-pipe the house now. We will be contacting them for any future projects. Great job, Rob, Curtis, and Brandon!!"

"Our family was having issues with black specks coming through hot water lines and into our daughters bath. We hired Benjamin Franklin and specifically Ilija came to inspect. He troubleshot the situation, provided a quote and eased my concern that a full hot water heater replacement may not fix the problem. He assured me it would with a guarantee. That alleviated my stress that the problem would be resolved and we proactively replaced an 11 year old heater."

"Keith was excellent from his first visit to explain what needed to be done on the kitchen drain. Afterwards, I requested a new water heater to be installed. Both were done this morning in a timely manner. Keith is very competent, takes the time to explain everything, and did an excellent job. I also was extremely thankful to Keith this morning as he identified a gas leak that I otherwise would not have known about. Because of Keith I was able to call the gas company and they came out within the hour to address the problem. I highly recommend Keith to anyone needing services. And, if I have any future issues, Keith will be the first person that I will call. He is a wonderful person, and he did an excellent job for me! Thank you Keith!!!"

"Brandon showed up on time, assessed the problem, went to his supplier to get the part necessary and installed it. Tested 3 times. Looks good. Done in about 1 hour including travel time to/ from supplier. Cost was reasonable and he is a very personable guy. And he warranties his work for a year! I will definately use him again."

"Great. Nick Diagnosed an electrical wiring issue, and repaired in the spot. $75.00. Worked like a charm. Prior company said $2k for a new control board, and possibly $6k for new unit altogether. Thanks Nick! You’ll be my go-to guy from now in"
