"We hired James, Dan, and their crew for a major deck renovation. The level of thoughtfulness and craftsmanship throughout the project was outstanding. This was not a simple refresh — it involved removing an existing hot tub, renovating a cabana, reworking the deck framing to convert it into a single-level deck, installing a new staircase, and adding a cable rail system. Every aspect of the project was approached with precision and care, and the finished product is without flaw. They were easy to work with from start to finish, handling decisions and mid-project modifications thoughtfully and professionally. The whole crew was consistently approachable and friendly, and clearly took pride in their work. Daily cleanup was always done well, which we especially appreciated since we had a puppy at the time. Definitely recommended!"

"I've personally seen how building or making modifications to your home can be very stressful. In early August of this year, we signed a contract with Ocean Break to demo our old deck and build a new deck/3 Season room combination. We found them on Home Advisor. From day one, the operation was totally professional. Peter Walsh, the owner of ocean break, quickly provided a proper contract capturing the results of the interview that preceded the start of work. The work promptly commenced shortly thereafter. The first phase of the project, the framing, was efficiently completed in a little over a week. Peter is the type of contractor who encourages you to be involved, choosing materials and colors and watching the daily progress of the project. He is happy to go over the work that has been done each day being sure to point out things he thinks you should know. All of the workers were extremely friendly and professional. My wife and I actually looked forward to seeing them bright and early each morning. Peter was extremely patient as we often changed our minds about design features and materials. He encouraged me, a veteran, to personally purchase many of the materials at Home Depot and Lowe's so that I could get my 10% veterans discount. The entire project was completed on schedule and within a reasonable Delta of the original projected price. As inevitably happens, we changed a few things from the original plan which appropriately increased the cost of the project. Peter always reminded us of when such deviations took place so that there would be no surprises at the end. The project was completed a little over a week ago. There was the inevitable punch list at the end which Peter took care of immediately. He even reused the section of gutter that had been cut off the house to accommodate the new room to save us money. With two weeks remaining in the project, Peter gave us a final figure and he stuck to it. So, now my wife and I have a three Season room and deck which we love. and, I'd like to think, we also have a good friend in Peter Walsh whom I highly recommend. One final point. As I watched the final vinyl plank be installed on the floor, without a single plank being ripped, I realized that, because it fit perfectly, the room was perfectly Square. Now that is skill and craftsmanship!"

"I can not say enough about John and his team! From the first time I met John, arrived on time, spoke straight and honestly about what needed to be done. I agreed with his rationale, asked for a quote, received it as promised and it was very reasonable compared to others. The work started on time, status and communication was a 10 out of 10. Most importantly the work was completed as scheduled and the work was just outstanding! I’ve already recommended him to 3 friends. Can’t say enough positive things about his work!"

"Our addition is fabulous. Came out beautifully. The workmanship is amazing. The work is excellent, from build to finish carpentry. We will live here for 25 more years and enjoy the fabulous space. We added 650 square feet of living space, half being a brand new kitchen. We converted our old kitchen to a wet bar and additional living space. Upstairs we put on a whole new bedroom and converted the old bedroom to walk in closets and a beautiful (spa-like) master bath. Along the way we made some adjustments to the original plan, and Liberty was very accommodating. Every time I walk in the house I have to pinch myself! Sometimes I can't believe it is our home."

"Highly recommend! I recently hired Doherty Construction for a major renovation project at my rental property and couldn’t be happier with the results. Dan stood out because of his knowledge, honesty, and fair pricing. When adding a new bathroom to a very old building, he quickly identified a major plumbing challenge that required new pipes in the crawl space. His assessment, estimate, and scope of work were accurate from the start. In addition to building the new bathroom, Dan and his crew renovated an existing bathroom, kitchen, rebuilt stairs, closets and installed LVP and Pergo flooring in several rooms. The quality of the workmanship and attention to detail were excellent. Dan was professional, responsive, and great to work with throughout the project. He was especially helpful in brainstorming solutions and navigating the inevitable surprises that come with renovating an older property. The project was completed on time, and I would absolutely hire them again!"

"To be fully honest, at first I was a little skeptical, as I am with most contractors, but they came in on time, were very clean, and were punctual about the things I asked for and needed done. The crew was efficient and the work was done correctly. They even helped and built my elderly neighbor a garage bathroom after seeing the work at my house. I definitely will have them back to build my ADU for my in-laws."

"Hired David Pierre, his crew and sub-contractors to install a new bathroom, remodel an existing bathroom, convert an attic to living space, install spray insulation, and rewire our 180 year old house in Plymouth, Ma. David impressed me with his professionalism and straight-forward approach, and I was not disappointed. Honest and committed to the end. Construction jobs always seem to take longer than expected, and this was true here, as well, but I think it is due to the nature of the business -- coordinating the schedules of several subs and dealing with unanticipated issues, especially when working on an old house. David juggled it all well. His core carpentry crew, Paul and Derek, were skilled, dedicated and responsive to requests. They kept the ball rolling forward. Good quality work at reasonable prices -- it would have cost me substantially more to use one of the larger home remodeling firms and I probably would get far less top-level attention."

FAQs for addition to existing structure building service projects in Westport, MA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
