"We had a very small roof area need to be repaired. I sent request to multiple company to give a service quote. Few of them sent me replies and stated that they are too busy to come. Matt of MMP Consturction's contacted me promptly, scheduled an on-site visit and gave us a quote right away. The work was then scheduled and finished quickly. Matt did great job on reaching out, effective communication, and always arriving on-time. He also gave an evaluation on our roof condition. Also, Eric and Don did excellent job on finishing the project. They are all very polite, knowledgeable, and showed their professionalism. We would like to express our sincere appreciation to Matt and his crew. We are very grateful for having them arriving on-time before the winter storm to prevent potential damage of the house. From their react, we see a warm heart. No job is big or small, all jobs are equally important. Understanding the difficulties of others, for the people, been appreciated by the people. Thank you again for your high quality service. We definitively recommend MMP Construction Inc. to anyone for any related home project."

"I hired Jesse's company to repair violations in the building code. Jesse's employee was very punctual, professional and a very skilled tradesman. I noticed during the project that they took pride in their work, and always went the extra step to absolutely do everything right. This experience renewed my faith in some contractors. Anything and Everything will be my only phone call for any work around the house. Even his sub contractors were a reflection of his company. Talented and professional with competitive pricing."

"When you find a great contractor, don’t let them go. ;). I hired Tim to build a screen porch under my deck but added several projects as I recognized the high quality of work and attention to detail from his crew. In addition to the screen porch, they built a deck extension - so nice that I decided to have them replace the existing deck, installed a basement slider and replaced the door, installed a new fence and built a shed. Tim was responsive, open, honest and receptive of my requests and additions during the project. Great experience working with Tim and his crew: Dan, Brian, Eddie and Ben. Great job on all the work - I’ve received many compliments from neighbors and guests on the work you did! I can’t recommend Tim and his crew enough."

"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."

"This is the 2nd job we has Steve do for us. The was a min bathroom renovation and also kitchen backsplash. Bathroom came out great. He walled off a second door to access the bathroom, ripped out old tile, and put down new tile and installed a new vanity. Very happy with the finished product. Steve also did the backsplash in the kitchen. It came out perfect. I would definitely recommend Steve for any home improvement projects you may have."

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