JJ Welch Construction

We found ourselves in desperate need of a competent GC for our South Boston tavern after our initial GC didn’t work out. Justin came onsite and personally looked at the space. He immediately understood our vision and was genuinely excited to bring it to life. He worked very hard during the bidding process to meet our budget needs without sacrificing quality, which allowed us to work with some incredibly talented subs. Our project manager Shawn was patient and always available, maintaining great communication along the way. While we had a few Supers throughout the process, Russ was an absolute standout, ensuring important design aspects were installed perfectly. His attention to detail ensured visual design goals were met (and exceeded). We can’t wait to work with JJ Welch again on our next projects - Justin and his team are talented, kind and know how to get the job done. I couldn’t recommend them more!

JJ Welch Construction was an exceptional partner in bringing Boston Provisions Market to life in the Seaport. This project meant a lot to us—it’s the coming together of two legacy Boston brands—and the JJ Welch team treated it with the same level of care and ownership. They were responsive, thoughtful, and deeply committed to delivering a high-quality result. No buildout is without challenges, but what matters is how a team responds—and JJ Welch consistently stepped up, stayed solutions-focused, and kept things moving. We’re incredibly proud of the space we’ve created together and grateful to have had them as our construction partner.

These guys are the real deal. Save your time and energy and just go with the pros. JJ Welch was professional from start to finish. It really is such a peace of mind knowing you’re in the right hands when you’re making a large investment. They send weekly reports and keep communication clear from before you start, all the way up to even after you open for business. Thank you guys! It was a pleasure to work with you all.

I would strongly recommend JJ Welch. They did an outstanding job on our Hilliards Chocolates flagship location in West Newton. We had a very tight timeline to renovate a 100-year-old bank building and open in time for the holidays. JJ Welch got it done without sacrificing the construction quality and detail that were so important to us. Justin and his team were a pleasure to work with throughout. Strongly recommend.

We had a great experience with JJ Welch Construction! Our office renovation was tricky due to the age of the building (100 years old), but their team did an amazing job. Everything came out beautifully, and they stayed right on schedule. Highly recommend them to anyone looking for reliable, high-quality work.
