"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."

"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."

"It went great. Chris built our custom home exactly to our specifications. We lived out of state for the entire build. Chris maintained open lines of communication with us so that we always knew what was going on. His work is impeccable. His attention to detail resulted in our dream home being exactly what we expected when we hired him. His group of subcontractors were great throughout the entire process. I have not spoken to anyone in the area that has anything but praise for Chris and his work ethic. Chris came highly recommended by a number of people and I would carry on that tradition and recommend Chris Johnson for any construction project from a remodel to building a new home from the ground up. I would certainly use Chris again for any future construction needs."

"Xavier and his team completely brought my water damaged condo back to better than new condition. He is easy to reach for concerns or questions. The teamwork in removing and replacing my granite counters before/after the hardwood flooring was replaced was something to watch. They deserve higher score than is offered!"

"Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

"Couldn’t have asked for a more honest and trustworthy contractor. After letting my previous GC go, Mike and his team were a breath of fresh air. Extremely impressed and grateful for their work. Highly recommend. Should have called Twin Timber first."

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