"WR Builders Inc. is an excellent construction company that provides high-quality workmanship. We hired them for an addition to our home, and they did an outstanding job. They were punctual, professional, and took the time to explain each step of the process. The addition blends perfectly with the existing structure, and we are very pleased with their work."

"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."

"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."

"For our home addition/renovation we are very grateful to have found Richard Connolly and his site iCornerstone. Our vision was a Two-story + basement + livable attic space home addition which would provide significant practical square footage to our existing house and integrate seamlessly with it. We interviewed a number of general contractors but we were overall a bit uncomfortable after the interviews due to gaps in transparency regarding how costs were calculated and how timelines were established, resulting in some lack of confidence. We happened upon Richard’s iCornerstone site via Angies. Richard provided an extremely transparent and detailed description of his unique and practical process, which delivered a set of superb designs along with a truly logical, transparent, and honest listing of costs, both materials and labor, at all stages, and how those costs were derived. Richard also delivered transparency on timelines, and he provided recommendations for all the needed tradespeople that he had historically a close working relationship with; alternatively we could have selected tradespeople of our own choosing. Richard and his process gave us the utmost confidence for proceeding. We proceeded with our renovation under Richard’s guidance and his own crew and the entire process went according to plan with excellent communication, rapport, and confidence at all stages from excavation to final finish work. Transparency, confidence-building, dependability, highly knowledgeable, customer-friendly, and results-oriented are all terms we would use to describe Richard and the iCornerstone process. We strongly recommend Richard for anyone contemplating any home renovation or home addition, large or small."

"This is the second time we have had Perry Brothers Construction do work for us--and we will definitely use them again for upcoming projects. We are consistently impressed by Bill Perry's responsiveness. He is available during the planning stages, throughout the construction phase, and in the months following the work. I can't emphasize enough how much we value that level of communication when we are saving up money and investing in projects for our house and family. Bill helped us to bring our ideas to fruition, giving advice along the way about the best layout for the master bathroom. In addition, we were very pleased with the workers (Bralio, Tony, Scott, the two Mikes, and Kenny), who were always polite, courteous, and helpful. They took pride in their work and took the time to answer any questions we had. Whenever I follow up with Bill with a question, he is quick to respond even though the project has been complete for several months. This is why we will continue to reach out to Perry Brothers Construction for future projects."

"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."

"We hired Joe and his team to build a deck on the back of our home and gut renovate our kitchen. The final products look amazing and we’re very happy with the new spaces. Joe and his team did high quality work and were very friendly. These were our first Home renovation projects and we plan to hire Joe again in the future."

"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 am extremely happy with the painting and carpentry work done by D&S. The workers came every day and worked long hours to get the job done. Not only did they do a great job but they were pleasant and courteous as well. I would not hesitate to hire them to do additional work for me and I have already referred D&S to others."

"Jason and his team did a fantastic job on an external stairwell for our property. It is now the nicest part of our house! Jason is personable and professional. Communication was easy throughout. Jason works as an inspector in his home town, which made me feel very comfortable that his work would be to code. He gave us a fair quote and not only stuck to this, but also adjusted the price downward when he did not use some materials that he anticipated needing initially. I will certainly be using Jason's services in the future if needed and would highly recommend Mason Sky."

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