"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."

"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."

"Every aspect of this project, from planning and architectural work to contractors, sub contractors and coordination was 100%. I received a spreadsheet every week with expenses as compared to budget including all materials and labor. Each step of the project including consultations, advice for saving $$ as well as suggestions for improvements in existing HVAC systems were valuable. All contractors were 100% reliable, professional, were creative and constructive in addressing challenges that emerge in any project and demonstrated outstanding follow through. The shop is extremely comfortable even on the coldest days and maintains even humidity for the wood. The project was on budget, on time and exceeded expectations, particularly with regard to workmanship, communication and professionalism."

"Wallpaper removal = A; plastering = A-; painting: C+. We were disappointed in the overall experience. They were kind enough and their wallpaper removal and plastering was great, really solid—but on the final day, they rushed with the painting to get it done on the original time frame, and while one room was top notch, another was above average, and the bathroom was very sloppy. There was wall paint on our bathroom tiles, vanity, and shower; unsanded/unsmoothed plaster chunks that were just painted right over and were unsightly and lumpy; peeling caulking; parts where the paint was crooked or misaligned with baseboards; paint dribbles on floor and utensils on counter; and they did a poor job cleaning up, with plaster dust everywhere, paint to be cleaned up in the bathroom, and paint and plaster dust in, on, and around our cabinets. One of the crew members’ painting skills was just rushed and poor and it detracted from the others’ skills. By the time the job was over they rushed to get out of the house and did not carefully complete a walkthrough."

"The CP construction crew were very hard working and competent. Clod as the owner is extremely customer service oriented. He communicated with me throughout the permitting process, the build and the inspection process. The new deck and stairs look great and bring compliments from all the neighbors. I will definitely reach out to CP construction in the future."

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