"We recently completed a kitchen and bathroom renovation and are very pleased. Having previously practiced construction law, I was particularly impressed with Eric's communication skills, responsiveness, and willingness to answer any and all questions we had without getting defensive. I think that is a rare quality in the construction profession. His crew Mike and Dave always were pleasant and friendly with my kids and me in the mornings and were incredibly hard workers - working through that awful heat wave in mid June and finishing the job on time."

"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."

"Everything went very well. Had to push the start date past winter. Matt is very responsive on the phone and the guys were on time and finished the job in 2 days. Nice group of guys would definitely use for more extensive work."

"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."

"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."

"Any construction can be stressful, but with Liam and his team I was in good hands. I had some upgrades to one bathroom and a tub to shower conversion in the master bathroom. Liam was clearly very knowledgeable, and his workmanship in both bathrooms was impeccable. He answered all my questions, had great suggestions and was very responsive whenever I needed to contact him. The demo in the master was completed in a day, and the guys cleared everything after they finished. The tile work was meticulous and just beautiful. I highly recommend Liam Neary Construction."

"My triple decker decks needed structural repair. Ed was very professional and a great communicator. He provided a fair estimate and was able to stick to the budget. The finished decks look great, and I would definitely hire him again!"

"Kinsella Built was great! So good that we have recommended them to all of our friends (now that is a true testimonial of their work). Our job was significant. We put on an addition to the house, created an open concept inside and finished our basement. The entire job was 7 months. Yet each day they showed such work ethic; always showing up at 7AM and putting in a full day work. They were professional, created a very quality product, were reasonable and finished the job on time. You can't ask much more of that from a contractor. For all of our future construction products, we will be going with Kinsella. Thank you to James & John (and Ian, and crew) for their wonderful work. We love our "new" home!"

"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 Somerville, 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.
