"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."

"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 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."

"Three terms you don't hear when speaking about contractors : Honesty, timely and effecient and pride of Workmanship. If you use Liam Neary Construction you will be using these terms and smiling as you tell others about your amazing experience. I had a leak in my roof with water coming in through the chimney. The water came into the utilitiy room creating a mini swimming pool and the hot water tank shut down. Liam came out within an hour of my phone call got my water running showed me how to clean the sensor for the future and reset the hot water tank. He scheduled to come out later that day to replace flashing on the roof to hopefully fix the problem. Unfortunately for me, it was not the full resolution. In the next rainstorm, I got water in the chimney again and reached out to Liam. This time it was a saturday and was thinking I might see him at the start of the work week or need to pay crazy money just to get him to show up. This was not my experience he showed up in 2 hours reviewed what he had done and come up with a new solution. He determined that the chimney needed some additional work and adjusted the price because of the original work that he had done correctly, but did not solve the problem completely. This contractor is the real deal. If you have a problem give him a call today. He will make your life easier and resolve your problems quickly. For the job done right call Liam Neary."

"Derek was quick to respond and jump on remodeling our bathroom before officially moving in. As project continued he kept us up to date and pointed out issues with existing structure around floor and window. Within few months the bathroom remodel was complete. Bathroom is beautiful and James did great work on tile/shower area."

"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."

"I wanted a shower expanded. George Mavridis's estimate was very competitive but I hired him because I knew he was honest, quality focused and an open communicator. He has a small crew and excellent subs so he's not super fast. But Mavridis is excellent. One example: The shower needed a new fan, vented through the attic roof. The attic boards were all cut (before my time) in half when insulation was installed. The attic floor was unstable and unsafe. George was very busy but he had his team replace the boards with plywood panels...for 20% less than I expected. Why? Because he wanted to make sure I would be happy when the job was done. I could give 4-5 other examples but you get the point. If you hire George, you'll be pleased."

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