"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."

"Our existing bathroom was a half bathroom with sink vanity, toilet, washer and dryer. We needed to eliminate laundry equipment and add shower and closet in the space that was designated for a washer and dryer, and add outside venting. We also wanted to tile the whole bathroom up to the ceiling. The job was performed excellent and we are very happy with the choices we made. Bill Perry and his crew were working in our house before renovating basement and building rooms there, so we knew that they were the best company for us. They were great giving us advice to improve on things that we wanted done, so they look and work better with a given space. We are very happy again. Thank you Perry Brothers!"

"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."

"Highly recommended. Jose and Cesar were great. They were reliable and their work was excellent. They completely remodeled our condo including 4 bathrooms, floors, fireplace/hearth, etc. It was a big job and they worked with us to make sure everything came out exactly the way we wanted. The cost was very reasonable."

"The project went great; I'm very happy with the final product. It lines up exactly with what I was looking for at the start of the project and looks better than I could have planned because of some great design suggestions from Wagner Home Renovation along the way. We ended up creating two separate closets from the previous closet incorporating some previously unused space in the condo as well. Both closets are accessed through very nice double doors. The laundry closet and general/clothes closet both look great. Wagner Home Renovation used high quality repurposed wood from a previous project and black iron rods to give the general/clothes closet great character. All of the work was very well done, and blends into the existing paint and trim-work so well, you can't even tell any work has been done. As an example, they added a wooden keystone at the enlarged entranceway near the new closets that was a very nice touch and feels like it was always there. They were able to save me money throughout the project by offering to use repurposed wood from previous projects that was often better quality than what would normally be used. Wagner Home Renovation does high-quality work and has a genuine interest in how well the end result turns out. They have a great attention for detail, offer great design ideas and options, and are responsive, honest, budget-conscious, flexible, reliable and easy to work with. I highly recommend them."

"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."

"Chris was able to put double closets in our bedroom. They now look like they have always been there. The work was done quickly quietly and efficiently. Pricing was very reasonable and the finish quality was excellent. I’ve seen other examples of his work and it’s well designed and definitely top quality. Happy to have worked with him."

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