"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"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."

"Wallpaper removal = A; plastering = A-; painting: C+. We were disappointed in the overall experience. They were kind enough and their wallpaper removal and plastering was great, really solid—but on the final day, they rushed with the painting to get it done on the original time frame, and while one room was top notch, another was above average, and the bathroom was very sloppy. There was wall paint on our bathroom tiles, vanity, and shower; unsanded/unsmoothed plaster chunks that were just painted right over and were unsightly and lumpy; peeling caulking; parts where the paint was crooked or misaligned with baseboards; paint dribbles on floor and utensils on counter; and they did a poor job cleaning up, with plaster dust everywhere, paint to be cleaned up in the bathroom, and paint and plaster dust in, on, and around our cabinets. One of the crew members’ painting skills was just rushed and poor and it detracted from the others’ skills. By the time the job was over they rushed to get out of the house and did not carefully complete a walkthrough."

"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"

"We were in a bind with an unfinished project and no contractor to fix it. Joe stepped in and gave us a reasonable quote and timeline to start the work. The project went very quickly and Joe was very clean, especially working in our kitchen. He was very responsive and lovely to work with and would hire again if (when) we need any additional work."

"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"

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