"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."

"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."

"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.

"Our existing bathroom was a half bathroom with sink vanity, toilet, washer and dryer. We needed to eliminate laundry equipment and add shower and closet in the space that was designated for a washer and dryer, and add outside venting. We also wanted to tile the whole bathroom up to the ceiling. The job was performed excellent and we are very happy with the choices we made. Bill Perry and his crew were working in our house before renovating basement and building rooms there, so we knew that they were the best company for us. They were great giving us advice to improve on things that we wanted done, so they look and work better with a given space. We are very happy again. Thank you Perry Brothers!"

"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."

"
Antonio communicated clearly with me, every step of the construction process.  After removing the siding, there was additional water damage underneath that required additional work.  He carefully showed me and explained what had to be done, and we revised the scope of the work.  My husband and I felt that he showed a lot of honesty and integrity in carefully outlining and showing us additional work needed, that could not be seen until the siding was removed. We felt he was very fair with us in his pricing for the scope of the work.

He helped us review the composite siding options and warranties, and brought us samples for the siding and decking, at different price points and explained in detail differences between each. He and his crew came punctually and on the schedule that Antonio had laid out for us.  They were meticulous in their clean-up as well.

The quality of Antonio's work, as well as his careful product research and commitment to our satisfaction, totally surpassed our expectations.  We do not hesitate in recommending Antonio, and plan to have him renovate our bathroom in the Spring."

"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%"

"Excellent. We had a great experience and are more than satisfied with the work they performed. Derek and James remodeled our bathroom several years ago and we were very pleased then and immediately thought to contact them when we had some water damage to part of the exterior on the back room of our house. In addition to replacing the damaged clapboards, there was underlying structural repairs and carpentry/insulation work needed on all the windows. Derek and James responded immediately so we were able to get the work done before more water damage could occur. They do quality work, are attentive to detail, communicate well and clean up their workspace everyday. While here, we also had them repoint the stone foundation of the house to prevent and water leaks/rodent entry. They did a great job on that project, too. Couldn't be more pleased."

"Excellent! Liam is a quality craftsman. If you want someone who is professional, polite, and has an eye for detail then hire him. Liam not only picked out a quality door, but hung it to perfection. From the start, he was in touch with me via text. He sent me a photo of the door before ordering. He said it would take about 10 days to come in. He contacted me when the door was in and set up a date for install. He arrived 15 minutes early! , but didn’t ring my doorbell till 7am. He built a new door casing and installed a beautiful oak sill. He installed the door and provided plastic on the outside to protect it from the coming rain. ( not all contractors would do that) He cleaned up after the job and sent me a text to let me know the job was done. ( I was working in my office in the house). Liam is an A+ contractor. He does everything right from start to finish. He is exceptional and has a fair price. I will definitely hire him again for any future house projects, and you should too!"

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