"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."

"Sean and his crew are truly Professionals within this Industry. Courteous, Friendly, Responsive and produce Excellent Quality Workmanship. By far, Sean and his crew are the best I have ever had the opportunity to hire for a major construction project that resulted in a comfort level knowing that everything was being handled properly. Construction is a challenging venture when putting on an Addition to an existing dwelling. There are many obstacles and challenges that can be faced throughout the project and within the home. Sean and his Team went over and above and addressed each challenge professionally and with timely resolution. I couldn't ask for any better service and results! The addition came out beautiful, I have an awesome Garage and my Wife is ecstatic with her new Mud Room and Pantry! I would recommend Hand and Some for any project that you may need."

"I’m generally not one to write reviews however when the experience far exceeded my expectations I believe in giving credit where credit is due, especially when it comes to small business owners. When I began the process of getting quotes to build my 2 car detached garage back in March, the most important factors for me in selecting a contractor were price, competence/quality of work, and trustworthiness (not necessarily in that order). Xavi, the owner of Xcc delivered on all three from start to finish. From the original quote which was fully itemized to show every last detail of the build to the final piece of trim installed, Xavi’s commitment to the job and open and honest communication style was exceptional. Xavi is a perfectionist, so if something isn’t 100% he won’t rest until it meets his standards - his crew is fantastic as well. Entering into a project of this size and cost can be a little intimidating given the amount of risk assumed by the homeowner and potential what if scenarios that can play out, ultimately will the builder will do what he says he will in the agreed timeframe? Xcc Builders will because Xavi is man of character who takes great pride in his work and fully understands the impact integrity has on his business’s reputation and long term success."

"We wanted to build on top of an existing garage, but extend out beyond the original building so as to accommodate two large rooms (a bedroom and a playroom), a bathroom and a balcony above and an outdoor dining-room below.. Turn Key Construction did an amazing job as you can see in the photographs. The entire team were courteous and friendly, and patient of the many changes I made as the build was progressing. They made the process enjoyable, and I really don't believe the work they did could be improved upon. We could not be happier with the results."

"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 Danville, 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.
