"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!"

"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."

"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 hit the jackpot when I chose Bob Ayotte to build my accessory dwelling unit in my son's 2 car garage. I should have purchased a lottery ticket! He is honest, a perfectionist, neat and very knowledgeable! Most impressive for me was the fact that Bob took the time to listen and understand what I needed to make this dwelling my "forever place" now that I have retired."

"We worked primarily with James to have a skylight installed in our recently constructed bathroom, as well as replacing an existing window in a bedroom, and adding a storm door. He was prompt and communicative, and very diligent about ensuring the space was clean and tidy after the work was completed. We are very happy with the installation of the windows and storm door and would recommend!"

"I hired Jesse's company to repair violations in the building code. Jesse's employee was very punctual, professional and a very skilled tradesman. I noticed during the project that they took pride in their work, and always went the extra step to absolutely do everything right. This experience renewed my faith in some contractors. Anything and Everything will be my only phone call for any work around the house. Even his sub contractors were a reflection of his company. Talented and professional with competitive pricing."

"Humberto and his team were terrific! They refinished the walls in 3 rooms of our house and their work was top notch. They removed wallpaper, sanded, plastered and painted our walls so that now they look pristine. I asked them if they could put in new doors and they did a great job with that too. I would refer this team to friends and family and will be using them again for other projects."

"Gil and his team did an outstanding job on our staircase renovation. They rebuilt the banister, handled the drywall, and refinished, and everything came out incredibly clean and precise. The craftsmanship really stands out, from the smooth lines of the railing to the attention to detail around the steps and finishes. The space feels completely transformed. They kept the work area tidy throughout and were professional from start to finish. Solid, high-quality work, I would absolutely recommend them."

FAQs for addition to existing structure building service projects in Concord, NH

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.
