"When we started our plan of remodeling, the first thing we did was the complete roof replacement including kitchen vent & duct pipe installation to the roof, and new installation of attic ventilation. MMP did not only completed it just as agreed but also very efficiently. The crews were friendly, professional, and careful. The jobs were carefully managed and implemented effectively. I was impressed by Matt, who is the manager, and he does an outstanding job in managing the crews and the progress of the situation, and the communication was clear and always to the point. We then moved to initiate a search for a contractor of two bathrooms remodeling after completing the roof and attic vent, MMP was one of the many candidates. Matt has had not only the best idea and proposals but also shown an impressive & professional sense of evaluating the project accurately, including the possible structural modification as well as a competitive estimate of the cost of the build. His proposal included a rebuild of a wall of the bathroom to expand another one adjacent to it. Matt accepted to use my schematic design image (made with a software tool) and a spreadsheet list of the fixtures that I created - as many as fifty items including TOTO, Grohe, American Standard, Panasonic, and IKEA - to start the job (later changed some of them due to local plumbing code compliance) After beginning the bathroom remodel project, Matt shared what jobs will be done with us timely and efficiently via text so that we feel comfortable enough in knowing what is going on while living in the house of dust & noise from remodeling. The crews, Zen and Mark, were very courteous, extensively experienced, reliable, and friendly with excellent communication, sometimes with songs of 80s rock music. They ask me when more precise specifications are needed and notified me when they feel advance notifications are required. When a change is necessary due to inspection, they informed me and clarified what and why. I have never felt uncomfortable in living together with the remodel job which has lasted over four months. The completed two bathrooms were stunning, just as I imagined. Matt, Zen, and Mark have proved their strong & thoughtful expertise and lived up with my request patiently until completion. Great job. A home remodeling project cannot be successful without having a trusted partner, and my experience with MMP has led me to be glad to share my confidence that MMP has a credential to become your reliable partner to manage a construction project together."

"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."

"Liam and Kevin were incredible professional and finished the job in record time! We were on a very tight timeline and they made themselves available to start and finish the project before our store opened. They had great suggestions and knowledge on what we could and could not do with the space structurally, and we could not be happier with the end results from Neary Construction! I'd recommend Liam and his team for any size project, and will be using them for any other construction needs - they did an incredible job!"

"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 hired US ProPaint and Renovation after meeting JR, discussing my project, and receiving what I thought was a fair and thorough proposal describing the work to be completed in 2 bathrooms. The team that worked in my home was professional, and they arrived on time each day. They were very careful to clean up after themselves each day. JR and his team also made sure, for each key piece of the project, that products were installed as I wanted them and that I was pleased with their progress. The team removed a vanity and granite countertops, installed a new bathroom vanity, installed LVT flooring in 2 bathrooms with transitions to meet the existing wood floors, installed new toilets, and then painted ceilings, doors, trim, and walls. The entire process was excellent and the best experience I’ve had with a company doing renovation work in my home. I’d use US ProPaint again and have recommended them to others."

"Pedro Quissanga was wonderful throughout the process. The project started out as a porch window replacement with an architect drawing plans, but once we started construction, we discovered that the whole underneath part was rotting and needed reconstruction. Pedro and his crew were hard working, reliable and careful, and his price for all of the work was very reasonable. When something went awry late in the construction, Pedro took it seriously and got people over within hours to locate the issue and fix the problem. Even though the project ended up being much more difficult than initially expected, there were never any unexpected charges and the additional work was at a consistent high level. We recommend Crystal Renovations without reservation and have several neighbors using them now for small-to-medium sized projects."

"Humberto and his crew were fantastic and we will definitely hire them again for future projects. The quality of work is amazing. We're so happy with our new rooms! Humberto scheduled the first day of work within a week of us contacting him. He responded to all emails within the same day and always arrived on time or even early! In addition, Humberto and his crew were professional, courteous, and very neat. I highly recommend HS Plastering & Painting."

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