The basis of our success is the importance of open communication and flexibility on every project we undertake. Whether we are involved during the initial pre-construction or later in the process, our primary goal is to exceed our clients’ goals and expectations while preserving the architect’s design concept. Our portfolio of ground-up, renovation and restoration projects span through-out New England. We take pride in our practical, professional and safe approach we bring to our projects and look forward to bringing your next project to life.

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.

STEVE DIFILLIPPO, CEO

Davio’s Restaurant Group

Working with JJ Welch to build the newest Jaho Coffee has been an incredible experience. Compared to other construction companies we have worked with, JJ Welch has been incredibly responsive, efficient, professional and most of all transparent. They have gone above and beyond to hit milestones and help us manage the inevitable change orders that occur during construction so that we could stay on budget. The team they assembled from the subs, the on-site supervisor, the project manager and even ownership has been amazing. We cannot wait to work on our next project with them!

Jaho Coffee Roaster & Bakery

JJ Welch started building Just Salad stores in MA and CT for us in 2024, and we continue to engage them because of the service that we receive from the whole team. From the Superintendents that they assign to our sites, to the PM Tom, APM Brendan, and owner Justin. JJ Welch is fair and they do not nickel and dime us. They ensure that they deliver the best buildout to their ability and they do their best to get us open as soon as we can. Having them on my team allows me to sleep at night knowing that they find solutions for us and make my life as Director of Construction easier.

Renee Co, Director of Construction

Just Salad

Our Restaurant group has done many builds and renovations over the years. We have found Justin and his crew to be without peer. When you combine the quality along with the communication and flexibility the results are outstanding. They stand by and support their work. Our Company puts up a high bar when it comes to construction standards with a competitive price and JJWelch exceeds this with every project. I believe we have completed six projects already and have them lined them up for our future projects. I give my highest recommendation for using them for your construction needs.

Michael Smith, Business Manager

Serenitee Restaurant Group

The team at JJWelch provides exceptional work, always putting the client first. We’ve now worked together with their team for 3 years on 18 new locations across 7 different states from VT to TN and as their team travels, they haven’t missed a beat or deadline. We’ve worked with other GCs on new builds and rarely do you get calls from the owner to check-in on progress, or a project manager that cuts through the noise to be sure the build comes in on budget, on time, without cutting corners. With this customer experience we will continue building with JJWelch.

Great job JJ Welch. Your high quality of work and your excellent service gave us the results we expected. Communication was consistent and ongoing. The quality of your employees, as well as the quality of your subcontractors, was of the highest caliber.
