    “Nate and his crew have been a fixture in our house since we closed in the fall of 2022. Since then they’ve completely transformed our home into something truly stunning. We’ve re-done the kitchen, mudroom, second bathroom, and dining room. We’ve used Back Bay Builders to convert a garage into a workspace/hangout spot, and we’ve used them to renovate an attic bedroom into an office space. We’re using them yet again to renovate our primary bedroom, en suite bathroom, and laundry room in early 2025. Each and every project was done in a timely fashion, and completely up to spec. Our expectations were high, and they’ve consistently exceeded them. They’re professional, communicative, courteous of our privacy, they treat our dog really well, and they’re just a really good bunch of dudes. I couldn’t recommend them more! 5 stars, 10 stars, 1 billion stars, they’re the best.”

    “We had a very positive experience with Back Bay Builders. From the beginning of the process when we collected bids on the project through to the very end and completion of our garage, it was an A+ experience. Nate is a hard working, honest and diligent business person/builder. His pricing is fair and market based. His communication skills are outstanding. He and his team are excellent craftsmen and we are thrilled with the quality of the work. They also have great subs and were willing to work with the ones we are already using like our plumber. They had great design ideas along the way including the back wall of our garage (aka our Sports Wall). And, they are VERY tidy. Every day when they left the worksite was in tip top shape. Lastly, all 3 of them are so kind and immensely likable.”

    “Nate took on some unique and challenging projects with us. Everyone on his crew and all the subs he brought in were professional and courteous, meeting and exceeding our expectations - from continuing to smile when the cast iron tub needed to come down the stairs (and go back up) to shoveling the front steps (adjacent but unrelated to and outside their work area) as they cleaned up at the end of a snowy day. We are thrilled with the finished spaces and would not hesitate to hire Back Bay Builders for any future home projects.”
