"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."

"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."

"Planning: We met with three contractors and reviewed small, medium and larger options for our existing space. Ryan from Norman Builders won us over with his confidence, organization and no problem attitude. Of course we had concerns and questions, but it was clear he had worked in colonial houses before. What really won us over was his excitement to do something different with our space. From day one, you could tell every detail of this job mattered as this was a new way to design a traditional space. His timelines, pricing and execution plan was clearly laid out. As a GC, he organized everyone from; designer, permits, dumpsters, demo, electric, plumbing, painters, floors, ceilings, etc. He would do it all. The Job: Completely gut our existing kitchen and formal dining room. Remove a wall and install a steal support beam. He'd then move the kitchen to the old dining space and make the old kitchen a common area with built in desk, bench and bar area. The dining room would then be moved to our four season bonus room. Floors, wall, ceilings all came down. All new plumbing and lighting throughout the first floor. Execution: I mean, its funny to say, but we miss these guys. They practically lived with us for the summer. Couldn’t have been better with our entire family (kids and dog included) Everyone was so respectful of world climate (summer of Corona) and space. Of course you need patience with the process. Timelines were clear and the job finished slightly ahead of schedule. In the End: I mean, wow. When we looked at the blueprint on day one, we legit thought they shared the wrong plans. We couldn’t imagine everything we wanted would fit. They nailed it. It’s a dream space for our family and we couldn’t be happier. We couldn’t recommend Ryan Norman Builders any higher. We can’t wait to have them back to work on the upstairs next."

"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!"

"Derek was quick to respond and jump on remodeling our bathroom before officially moving in. As project continued he kept us up to date and pointed out issues with existing structure around floor and window. Within few months the bathroom remodel was complete. Bathroom is beautiful and James did great work on tile/shower area."

"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."

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