"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!"

"I was happy with the work done by Matt and his crew on my roof replacement. Of the highlights, Matt excelled at customer service. I had spoken to several contractors during the bidding process and Matt clearly stood out as someone to provide detailed guidance and credible advice on the project. As my roof was being replaced as part of an insurance claim, Matt took the initiative to bring in additional contractors to build out an initial estimate for all of the work, to get things moving with the insurance company, which was a huge help. Matt took things a bit further and spoke directly with the insurance company regarding details of my roof and other work that was not started yet and was able to help me gain significantly more coverage than originally provided! Matt was always available for questions and promptly returned my calls and emails throughout the process. In one instance, I had requested that they hold off on installation of the ice and water shield one day due to the cold temperatures. Matt agreed to this with no hesitation, even though it required them to work the weekend to complete the work. Per my inspection throughout the roofing process and after, everything looked good and I found only a few things that were missed, which Matt took care of immediately. Some mess and nails were left behind after the work, but it was fairly minimal. Due to the scale of the work, Matt / MMP did bring in subcontractors to perform much of the standard roofing work. I would have appreciated if MMP was more forthcoming about this earlier in the process. MMP had someone from their team on-site for the entire process, but I think that they could have kept a closer eye on the sub-contractors work. For the more challenging tasks, Matt came out and did the work himself. He and his team worked hard throughout the process, working long hours and through the weekend to get everything completed in a timely manner and reduce risk of water leakage in case of rain. I will certainly consider MMP for future work on my house."

"Corey and his team are great to work with. He is a prompt communicator and is very organized. He also has a great attention to detail and ensures the project is perfect before claiming he is done. He is easy to work with and was able to make our ideas a reality. We have used him for several projects already and have him lined up for another. I highly recommend St. James Construction."

"JWC builders are seasoned contractors. They do amazing work! They show up on time, and work throughout the day. The owner of the company, John Wrobleski, was always in contact with me, letting me know what was going on throughout the course of the deck building project. I have hired them for many other jobs as well and they always do an impeccable job! I will definitely hire them again for future projects!"

"After having numerous contractors not show up to bid or throwing ridiculous quotes our way, we were fed up. I decided to reach out and try Angi. Jim's name popped up, I decided to give it one more shot. We are so happy that we did. Jim was super responsive and came right out to the site. His experience showed immediately. We weren't sure if we wanted to do new construction, a Barn conversion or an addition. Didn't matter to Jim. He was able to quote all variations on the spot! Unheard of with other contractors. We hired him to do a 20x24 family room addition with a full foundation, replace all the existing windows and doors along with new siding and trim for the whole house and addition. His contract was concise with price breakdowns of all phases. He never wavered from his quote or promised timing. His crew consists of family and long time friends. They have tons of experience and it shows in the quality and speediness of their work. I'm still amazed at the precision of the framing. Being an Engineer and machinist, I can really appreciate accuracy. He handled a few change orders with the same integrity. The final project is beautiful and the addition looks seamless. Jim and the crew were friendly, clean and very easy to communicate with. Jim is excellent at explaining all aspects of construction and was always willing to teach me, when I had questions. Couldn't be happier!"

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