"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."

"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"The workers came on the appointed day with a longer ladder, as suggested.    Terry called to ask if he and an assistant could come by earlier than the original appointment time because they had finished work scheduled in the area earlier than expected; that certainly worked for me.    He surveyed the roof, took pictures and reattached a loose shingle that had fallen into the gutter.   Terry showed me the pictures of the roof from many angles; they showed no other repairs were necessary at this time.  Terry asked if there was anything else that required attention, but nothing else was immediately apparent.  He gave me his card and explained that the company does general contacting work.  
I am very impressed with the speed and efficiency shown today and won't hesitate to call MMP Construction in future if I need general contracting work done.

"I had an excellent experience with The Curtice Group. I would highly recommend them and I'd use them again for a future project. We utilized the full design to build service to add a master bedroom/bath/closet, a 2nd floor 3x10 balcony, and renovate a number of items associated with the build including a re-build of an existing bathroom.  We live in an old house and Scott did a fantastic job making use of space and working with the house limitations, and overall, giving us lots of details and options as we had back/forth meetings on the concept.  The design process was great. We had a number of meetings starting from a wish list that expanded to initial design concepts and then to more final concepts. Scott made excellent use of space and gave us a lot of options which for budget reasons, we had to slowly narrow things down to a final concept. The build was equally fantastic. Not only was the quality extremely high but they stayed on schedule and never skipped days; there was always a team working every day. The workers and subs were reliable and on schedule, which you dont see too much of. Not only that but juggling/managing the schedule when the different subs had to show up was very impressive as the goals for each week were always met. Scott and his team really care to make a top-quality build. A few family members in construction walked through a few times and commented on the high quality of everything.  The house had two surprises as we things opened up.  Somewhat expected as unwelcome as it was: a bad foundation and a roof with upgrades needed. Both these items were attended to very quickly and surprisingly got back on track sooner than I thought it would.  Budget: Scott's budget was extremely accurate. Aside from the 2 house surprises (above) and the additional rise in lumber cost during COVID, all numbers and quotes lined up extremely well. Yes the cost went over the estimate but I hold no concern over this, since it was due to two extra side projects (that were impressive accomplishments). When the project was done Scott made sure we were happy with everything. A few items to touch up were quickly dealt with and Scott really went above and beyond making sure things were 100%. No negative comments from me. Any items to nit-pick are not worth putting in a review: this was an extremely positive experience and I would recommend the Curtice Group and would/will certainly utilize them again in the future."

"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!"

"Russell Remodelling was by far the best outfit I have ever dealt with and I only wish that when we had the addition on our home built 25 years ago that I would have known them except that Tom Russell, the owner would have been learning to build sandcastles on the beach. Consummate professionals in every way. Never worried about a return call taking longer than an hour or a text if he were predisposed. The referrals I had gotten when beginning the deck were glowing, yet they pale compared to the actual finished work. His construction crew were extremely hard working and very friendly. One day they worked in 98° heat and had the attitude and smile of Cool Hand Luke building the road. I recommend Russell Remodeling to anyone who wants their home to make an impression on their guests as well as themselves and their family every day they enjoy living there. Feel free to call me anytime for a reference. 617-285-7088. With total sincerity, Dave Schultz"

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.
