"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 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."

"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 couldn't have been happier. They demo'd the old deck, disposed of the materials, and constructed the whole new deck within a week. The work was well done, once the job started it was done really fast even though it was horribly hot and miserable for them, and it was done exactly to code and I had no issues with the building inspector and got my certificate of completion with no changes. Jesse worked with me to tailor the potential options and choices to my budget. We used PVC decking with pressure treated rails. It looks great and I've gotten a lot of compliments on it. I'll be using them in the future when I need other work done."

"Antonio and his crew remodeled our front hall, completely relocated /
rebuilt our kitchen, and converted our 3 season porch into a heated
sun room. They did everything from the demo work to the final touches of
installing the back splash.
Antonio and his crew, (and I'm lumping in his
subs for the plumbing and electrical parts here), did an outstanding
job on our renovation project. Renovation projects can be stressful and
Antonio did a great job through the whole project. He was always
reachable when we had a question or a concern and always made it a
priority to make sure we were satisfied with the results. In some cases that meant working with us on what we wanted, leaving out samples for us to look at when we got home, or even sending picture text messages to make sure it's what we wanted before doing it. It's those types of things that make a big difference in the final result.
All renovation project encounter problems. In our case we had a few design
issues as well as delays with our counter tops that held up plumbing install and a few other things. First off these are problems that were not caused by
  Antonio's team but rather reinforce the need to hire a team like them who can help you through it and work around it.
Finding the right contractor is as much
about personality fit as it is about finding one with the right skill set. I'm going to level with you. My wife and I can be tough customers. An engineer and   and architectual designer by trade, I'll admit we can be picky about certain parts of the project. Maybe that's an understatement, I don't know, but more importantly I think that says something about our contractor. You have to Antonio for his patience, attention to detail and pride in his work. They were evident throughout the project and most importantly in the final result. I have no reservations about hiring him and his team again for future work to our home.
Of the 2 other bids we considered for this project, I'm glad we went"

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