Building Success Since 1852


JJWelch Construction, established in 1852 is a seven-generation construction manager/builder. 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.


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 was an absolute pleasure to work with. Communication throughout the entire process was superb. Joel and Tom did everything in their power to keep to our timelines and budgets while paying attention to quality in every detail. They were incredibly understanding when we had to majorly change the scope last minute and accommodated our every need. 10/10 would call them again for any construction needs. They are on your side!

Catalog Technologies, Inc.

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.

Serenitee Restaurant Group

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!
