"Eric's team rebuilt our entire three season room, which was not functional. It is now, thanks to Mike and Brian. It also looks very good! Mike works hard at getting things done, and teaches the younger crew very well. He is structured and trustworthy. He also was patient answering my questions (I always have too many..!). Brian pays great attention to detail! I was impressed by how good the tile work looks, and also how good the finishing of the decking to the landing looks like, which he did. They also had to partly redo the patio, and it looks better than before."

"I would highly recommend MMP Construction. Matt and his team are knowledgeable, friendly, and extremely hardworking. Even after running into some unexpected structural issues once the walls were opened up they still managed to get the job done in the time frame quoted by working extra hours and weekends. I was truly blown away by the level of dedication and service. Anytime a challenge came up, someone on the team was quick to provide a great solution. And the finished product is absolutely gorgeous. I would hire them again in a heartbeat.

"As a testament to how happy we were with our first renovation provided by the Curtice Group in 2021, which provided completely new kitchen/dining/mudroom/bath, we hired Scott and his team again in 2024-25 for another major renovation. This job was composed of 3 main parts: a gut remodel of our main bathroom, renovation of a large attic space (about 700 sq ft), and whole-home conversion from steam radiators (gas) to heat pumps including removal of all radiators and a chimney. The bathroom now is attractive and more functional, the attic adds a large amount of useful space as an office/kid room/guest area, and central air makes a more comfortable climate. I’m a big fan of the design/build concept, because you really don’t want to separate those two elements into different contractors, and if you find a talented company, they can handle all aspects of the job fluidly. Scott Curtice has a real knack for design, he is attentive and cares about details, and he will perform carpentry and touch-up work as needed. Moreover, he handled all the project coordination so that we could do the jobs that we do well, which do not include home renovation."

"Joe and his team are truly amazing to work with and their product is even better. I am an architect and have worked with Joe on several projects. I am always really happy to see their results, Joe makes sure to take care of everything so that it is done professionally, up to all building and code standards, and that it looks spectacular in the end. It's hard to find a GC that cares and is willing to go the extra mile for their client. Joe is someone I trust completely to get it done well and to listen to the clients need. I recommend him 100%"

"DiOrio builders did excellent basement work. Before DiOrio- my basement unusable, a dusty mess, the walls and ceiling peeling so bad, I couldn’t even walk in there without being covered in chalk. Quotes from other contractors were outrageously high, with a bunch of complicated add-ons. DiOrio builders found a solution at a price that made sense, they fixed exactly what needed fixing. They demolished the old structures, scraped the walls and ceiling, removed decades-old debris, sealed the foundation and put a bright white coating on the wall. Plus, once they removed all the debris, the air quality is much better in the upstairs of my house! I’m so happy they made my basement useable, and I will definitely be calling DiOrio Builders and Designers when it’s time to build a lounge down there."

"I recently had a home built for me in Kennebunk,Maine by Jason and the crew of Mason Sky Enterprises and I have nothing but praise for them, not only did they construct my home to the highest standards in an incredibly timely manner but they were also kind and considerate and endlessly patient when it came to my plethora of never ending questions which I am very grateful for. I highly recommend them for any job whether that be large or small. With much gratitude! SSgt.K Campbell USAF (Ret.)"

"Three terms you don't hear when speaking about contractors : Honesty, timely and effecient and pride of Workmanship. If you use Liam Neary Construction you will be using these terms and smiling as you tell others about your amazing experience. I had a leak in my roof with water coming in through the chimney. The water came into the utilitiy room creating a mini swimming pool and the hot water tank shut down. Liam came out within an hour of my phone call got my water running showed me how to clean the sensor for the future and reset the hot water tank. He scheduled to come out later that day to replace flashing on the roof to hopefully fix the problem. Unfortunately for me, it was not the full resolution. In the next rainstorm, I got water in the chimney again and reached out to Liam. This time it was a saturday and was thinking I might see him at the start of the work week or need to pay crazy money just to get him to show up. This was not my experience he showed up in 2 hours reviewed what he had done and come up with a new solution. He determined that the chimney needed some additional work and adjusted the price because of the original work that he had done correctly, but did not solve the problem completely. This contractor is the real deal. If you have a problem give him a call today. He will make your life easier and resolve your problems quickly. For the job done right call Liam Neary."

FAQs for addition to existing structure building service projects in Watertown, 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.
