"Planning: We met with three contractors and reviewed small, medium and larger options for our existing space. Ryan from Norman Builders won us over with his confidence, organization and no problem attitude. Of course we had concerns and questions, but it was clear he had worked in colonial houses before. What really won us over was his excitement to do something different with our space. From day one, you could tell every detail of this job mattered as this was a new way to design a traditional space. His timelines, pricing and execution plan was clearly laid out. As a GC, he organized everyone from; designer, permits, dumpsters, demo, electric, plumbing, painters, floors, ceilings, etc. He would do it all. The Job: Completely gut our existing kitchen and formal dining room. Remove a wall and install a steal support beam. He'd then move the kitchen to the old dining space and make the old kitchen a common area with built in desk, bench and bar area. The dining room would then be moved to our four season bonus room. Floors, wall, ceilings all came down. All new plumbing and lighting throughout the first floor. Execution: I mean, its funny to say, but we miss these guys. They practically lived with us for the summer. Couldn’t have been better with our entire family (kids and dog included) Everyone was so respectful of world climate (summer of Corona) and space. Of course you need patience with the process. Timelines were clear and the job finished slightly ahead of schedule. In the End: I mean, wow. When we looked at the blueprint on day one, we legit thought they shared the wrong plans. We couldn’t imagine everything we wanted would fit. They nailed it. It’s a dream space for our family and we couldn’t be happier. We couldn’t recommend Ryan Norman Builders any higher. We can’t wait to have them back to work on the upstairs next."

"I hired Handy & Some for a bathroom remodel. I received a quote quickly from Sean and he communicated very promptly through the entire process. His price was reasonable and he adjusted it fairly for additions and subtractions that we made. His subcontractors were reliable and everyone was pleasant and considerate while working in the house. Larry, who acted as foreman on the job, was great to work with and always going the extra mile to make sure that everything was done to my satisfaction. Job was completed on schedule and with high quality! Hire them if you have a chance!"

"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."

"Jim and crew are reliable and knowledgeable. I agree with all that Dana C in Kensington shared. We hired Jim to close in a carport for an addition by seeing the work he was completing for Dana. I then had him remodel an old garage that needed a face lift. We now have Jim building a ranch home for us from the ground up. It is going just as well. If only the prices due to the economy were not so disappointing. Materials are through the roof as a result. Here hoping for some REAL change in 2025 !!!!"

FAQs for addition to existing structure building service projects in East-Derry, 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.
