What our clients are saying

“We have used JJWelch Construction to build our restaurants and I cannot recommend them more. They always meet our budget and build first class restaurants. The jobs are always clean and organized and the weekly meetings with us are very professional and productive. The superintendent on our jobs is always a pleasure to deal with as well as the subcontractors. This is very important to us because Davio’s is all about hospitality. We love using JJWelch and we will continue using them forever.”

JJ Welch was the General Contractor hired to complete our Landlord scope of work for a new retail tenant at one of our Shopping Centers in the Greater Boston Area. From the RFP stage to project delivery and addressing punch list items, JJ Welch has been professional, prompt and trustworthy. This job encountered many unforeseen obstacles and JJ Welch handled them flawlessly by not letting them affect the schedule and by providing cost efficient solutions. In the end the project was delivered ahead of schedule and under budget exceeding our expectations and paving the way for a successful tenant fit-out.

At every step, they were extremely responsive and available. When the unknowns became known, they helped guide us through the options and always pushed for the best value solution without losing the integrity of the final project. […] Not much more we could have asked for!

Justin & Justin at JJ Welch helped us with our renovation and construction of an urgent care clinic in Swampscott. Justin Welch was an absolute pleasure to deal with- tough, smart, honest, fair and very responsive. There will always be problems in any construction with unknown unknowns and you want someone you can rely on to be fair and open and work with you to solve those issues. These guys go above and beyond.

JJ Welch did a fantastic job on building out our brewery and restaurant! Honest communication and a fantastic staff all around. They really went above and beyond to make everything beautiful and were a pleasure to work with. Can’t recommend enough.

As a business owner… I love when people deliver on what they say, and keep there word. J.J. Welch bent over backwards to give just what we wanted.
The crew worked hard from the time they showed up, until Justin handed me the keys, to the absolute most beautiful Salon in NewEngland…(no exaggeration). And we opened when we planned… right on time.
