Duty Mass Construction & Service is a Danvers-based general contractor - self-described as specializing in residential fix-and-flips - that a repeat customer hired first for a basement reconstruction, then again for a much larger full-home renovation including a two-story addition with a master bathroom, a new basement, and new siding and roof. Neto, who leads the crew, comes up by name in most of the company's reviews. The written record includes 17 positive reviews from 2020 through early 2026, most of them five stars, describing siding installation, a same-day porch replacement, an attic renovation with extra shelving thrown in, and various bedroom, bathroom, and repair jobs. Reviewers consistently describe the crew as fast, communicative, and adaptable when unexpected issues come up mid-project. Two things are worth knowing plainly before hiring. In April 2026, a reviewer left a one-star warning not to trust the company, saying it goes back on its word, without further detail. And in July 2023, according to a federal enforcement database, Duty Mass Construction and Services was penalized $97,418 for a wage and hour violation - a labor-law finding that predates most of the positive reviews on file but is a real part of the company's record. For a renovation or exterior project in the Danvers area, the bulk of the written record describes fast, quality work and a crew that customers hire again for bigger jobs - but the wage violation and the one negative review are worth asking about directly before signing a contract.
We first worked with DutyMass on a basement reconstruction and were so impressed with the results that we chose them again for a full home renovation. This larger project included a two-story addition (including a master bathroom) with a full basement, new siding and roof, and upgrades to the second floor. From start to finish, communication was clear, consistent, and honest—something that truly stood out and was reflected in the quality of the final product. The attention to detail, craftsmanship, and professionalism from both the owner and the crew exceeded our expectations. We absolutely love our “new” home and couldn’t be happier with the entire experience. I highly recommend DutyMass to anyone looking for reliable, high-quality work.
Don’t trust this guy he will 🤝 and go back on word.
I’m very happy with the siding work done by Duty Mass. The team was professional, efficient, and helpful throughout the process. The quality is excellent, and the project was completed on time and within budget. I highly recommend their services.
We just finished a modest-sized project (bedroom/bathroom) with Duty Mass and we really cannot say enough good things about Neto and his team. Hiring a home contractor is always a nerve wracking experience, it's a big investment of money and time, and you have certain expectations. Neto was responsive to our needs and questions, his crew was polite and respectful, and they worked hard! Some days arriving at 7 am and staying till dinner to finish that day's task. Neto was reachable when we needed him, always mindful of costs and added expenses. The project came together quickly, he pushed hard to get it done, working through bad weather some days. I love to see small businesses like this succeed because of great management. I would use Neto again in a heartbeat.
I highly recommend Dutymass! They did an excellent job on our project — professional, reliable, and with great attention to detail. The crew was respectful, worked efficiently, and made sure everything was done right from start to finish. I’m really happy with the results and wouldn’t hesitate to work with them again. Great quality and great service!
