"Eric and co are the best - attentive, listen, give their professional advice, and just do a great job. The project went really well - repaired water and bug damage and fixed what was originally done in a not so great manner. Our third successful project w/ Eric and team. Very pleased"

"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."

"We hired Joe and his team to build a deck on the back of our home and gut renovate our kitchen. The final products look amazing and we’re very happy with the new spaces. Joe and his team did high quality work and were very friendly. These were our first Home renovation projects and we plan to hire Joe again in the future."

"Pedro Quissanga was wonderful throughout the process. The project started out as a porch window replacement with an architect drawing plans, but once we started construction, we discovered that the whole underneath part was rotting and needed reconstruction. Pedro and his crew were hard working, reliable and careful, and his price for all of the work was very reasonable. When something went awry late in the construction, Pedro took it seriously and got people over within hours to locate the issue and fix the problem. Even though the project ended up being much more difficult than initially expected, there were never any unexpected charges and the additional work was at a consistent high level. We recommend Crystal Renovations without reservation and have several neighbors using them now for small-to-medium sized projects."

"Our house is 50+ years old and had the original casement windows, which were starting to fail. In addition, the exterior of our house need to be painted and there were a great deal of shingles or trim that was rotted and needed to be replaced. George and his team did an outstanding job, kept us informed as they went along and completed everything on time and on budget. We couldn't be happier with how the house looks. I would highly recommend Mavridis Contratcing to anyone looking for a contractor."

"Duncan Builders LLC I wanted to reach out to express my gratitude to Duncan Builders. On December 19, 2018. I signed a proposal to have Duncan Builders take care of the contract work and I needed to build at my salon. They moved a bathroom door from one wall to the next. Had their plumbers come in to create some plumbing through the floor into the basement and install a new water heater. All this was done to set up two free standing shampoo basins. Also completing the work with finishing trim. The team did an excellent job and was very punctual with the timeframe that was given to complete the work. I would highly recommend Duncan Builders for any of your commercial space build outs and other projects you may have. Extremely professional and I’m so glad that I chose them to be a part of creating my business. I couldn’t have done it without them and I’m so grateful for all of the good work that they did. Thank you again for helping me create my business Salon Artist. If there are any improvements that need to be made in the future. I will definitely be reaching out to Todd Wilkins of Duncan Builders LLC. Best, Christopher Kezik Salon Artist Owner"

"Phil coordinated and supervised the entire roof repair and shingling of our 200 year old house. He then stripped the clapboards to bare wood, replaced broken clapboards as well as soft wood behind some of them, before applying 3 coats of paint to the entire house. Phil told us up front that he took his time to do it right and would not be applying paint within three days of it raining., to ensure there would be no moisture under the paint. The work was done meticulously, with care taken to avoid any spillage or leftover material. I wish I could provide some photos to show his work!"

FAQs for addition to existing structure building service projects in Chelsea, MA

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.
