"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."

"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."

"We hired Redman to completely gut our kitchen and dining room and make them one room. All new cabinets, island, windows, floors etc. it was such a smooth process and the finished product looked like it came off a magazine cover. We were so pleased that we hired them again to remove our entire second floor and turn our cape style house into a garrison style. The transformation was incredible. We added a second floor laundry, bathroom, Master bath, guest room/office and attic. I would not only recommend them to anyone needing work I would hire them again in a heartbeat."

"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."

"Alan Haun, from Joal Construction offered great insight into chosing the best options for out needs and budget. Once our plan was in place, he ordered the materials, and coordinated the work, providing daily updates, and the work progressed seamlessly, and in a timely manner. His knowledge and insight are to be noted, and he really listened to what we wanted to do. He offered many good suggestions to ensure that we'd be very satisfied with the final product. We definitely will coordinate our next project with Alan!"

"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."

"I hired US ProPaint and Renovation after meeting JR, discussing my project, and receiving what I thought was a fair and thorough proposal describing the work to be completed in 2 bathrooms. The team that worked in my home was professional, and they arrived on time each day. They were very careful to clean up after themselves each day. JR and his team also made sure, for each key piece of the project, that products were installed as I wanted them and that I was pleased with their progress. The team removed a vanity and granite countertops, installed a new bathroom vanity, installed LVT flooring in 2 bathrooms with transitions to meet the existing wood floors, installed new toilets, and then painted ceilings, doors, trim, and walls. The entire process was excellent and the best experience I’ve had with a company doing renovation work in my home. I’d use US ProPaint again and have recommended them to others."

"Taylor was great. Mike Taylor came out and listen to what we wanted but also made some suggestions that improved the project. Once we finally go city approval for our new driveway his team showed up and made short work of it. The crew was very professional and friendly. They even moved much of the excavated dirt to our backyard to level a low spot, and spread it evenly even though I would have been happy with a pile. Good folks, would defiantly use them again. Driveway. Looks great and price was very reasonable.

"Chris did an excellent job designing and building a new deck for my house. He also came to the rescue when having to replace exterior doors after a robbery. He was great at communicating different options with estimates. I really appreciated his punctuality, professionalism, and hard work. Would highly recommend!!"

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