"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"

"For our home addition/renovation we are very grateful to have found Richard Connolly and his site iCornerstone. Our vision was a Two-story + basement + livable attic space home addition which would provide significant practical square footage to our existing house and integrate seamlessly with it. We interviewed a number of general contractors but we were overall a bit uncomfortable after the interviews due to gaps in transparency regarding how costs were calculated and how timelines were established, resulting in some lack of confidence. We happened upon Richard’s iCornerstone site via Angies. Richard provided an extremely transparent and detailed description of his unique and practical process, which delivered a set of superb designs along with a truly logical, transparent, and honest listing of costs, both materials and labor, at all stages, and how those costs were derived. Richard also delivered transparency on timelines, and he provided recommendations for all the needed tradespeople that he had historically a close working relationship with; alternatively we could have selected tradespeople of our own choosing. Richard and his process gave us the utmost confidence for proceeding. We proceeded with our renovation under Richard’s guidance and his own crew and the entire process went according to plan with excellent communication, rapport, and confidence at all stages from excavation to final finish work. Transparency, confidence-building, dependability, highly knowledgeable, customer-friendly, and results-oriented are all terms we would use to describe Richard and the iCornerstone process. We strongly recommend Richard for anyone contemplating any home renovation or home addition, large or small."

"I was happy with the work done by Matt and his crew on my roof replacement. Of the highlights, Matt excelled at customer service. I had spoken to several contractors during the bidding process and Matt clearly stood out as someone to provide detailed guidance and credible advice on the project. As my roof was being replaced as part of an insurance claim, Matt took the initiative to bring in additional contractors to build out an initial estimate for all of the work, to get things moving with the insurance company, which was a huge help. Matt took things a bit further and spoke directly with the insurance company regarding details of my roof and other work that was not started yet and was able to help me gain significantly more coverage than originally provided! Matt was always available for questions and promptly returned my calls and emails throughout the process. In one instance, I had requested that they hold off on installation of the ice and water shield one day due to the cold temperatures. Matt agreed to this with no hesitation, even though it required them to work the weekend to complete the work. Per my inspection throughout the roofing process and after, everything looked good and I found only a few things that were missed, which Matt took care of immediately. Some mess and nails were left behind after the work, but it was fairly minimal. Due to the scale of the work, Matt / MMP did bring in subcontractors to perform much of the standard roofing work. I would have appreciated if MMP was more forthcoming about this earlier in the process. MMP had someone from their team on-site for the entire process, but I think that they could have kept a closer eye on the sub-contractors work. For the more challenging tasks, Matt came out and did the work himself. He and his team worked hard throughout the process, working long hours and through the weekend to get everything completed in a timely manner and reduce risk of water leakage in case of rain. I will certainly consider MMP for future work on my house."

"If you have spoken to the rest now hire the best Liam Neary Construction. I bought a house last year and have probably replaced almost everything. I have worked with at least 20 contractors and not one of them comes close to the talent, hard work, dedication, and professionalism of Liam Neary. Everything he does from the moment he enters your home is done with thoughtfulness, skill, and integrity. He will listen to you, explain things to you, and give you honest feedback based on his vast knowledge and experience. He will send you a detailed estimate of the work needed within a couple of days and follow up with you. He is always available and gets back to you quickly. He respects your time and shows up at your home every day at 7 am and works 6 days a week. He checks in daily and several times a day if necessary to keep the project moving. He has a clean-as-you-go mentality keeping everything neat and orderly. He loves what he does, and it shows in the beautiful, finished products of his work. He will treat your home like his own. Do yourself a favor hire Neary Construction, you will have the work of a true craftsman."

"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."

He communicated with me throughout the permitting process, the build and the inspection process. The new deck and stairs look great and bring compliments from all the neighbors. I will definitely reach out to CP construction in the future."

"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 Mattapan, 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.
