"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."

"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."

"I am very pleased with the work completed by Crystal Renovations in my home. The company's owner, Pedro Quissalga, is knowledgeable and has a fantastic crew. He implemented the bathroom, laundry, and closet design ideas beautifully. A critical positive factor was communication. Pedro was responsive to my questions and concerns. He kept me informed every step of the way during the construction. Another important factor was their care in keeping the renovation project clean and organized. The team was also mindful of how the construction may impact the rest of the building and did their best to keep the noise level down. I highly recommend Crystal Renovations."

"Cannot say enough good things about Mavridis Contracting and its sub-contractors. This was a challenging project in part because the prior remodeling contractor (from forty years ago) cut many corners that needed to be remedied. Mr. Mavridis, his employees, and sub-contractors identified and explained every issue so that we could make informed decisions. The team was courteous, professional, skilled, and very tidy (cleaning up after each day). The finish work (tiling, carpentry, etc.) is excellent. Even the city inspectors provided unprompted compliments on the final product."

"These guys are the hardest working crew Ive ever seen. Showed up every day at 7am and stayed until 7-8pm every night! I cant say enough about their work ethic. Wladimir was great to work with right from the initial site visit, to the quote, and right up through the finished product. It takes a lot to impress me when it comes to projects. I have high expectations of how things are built and the final results. Id rather have quality work over saving a buck. I had multiple contractors out and narrowed them down and eventually chose WS Builders because of my interactions with Wlad right from the start. Very personable, great guy and listened to what I actually wanted and didnt just yes me to death. He knew exactly what I was expecting from the start and his guys blew away my expectations. We had been saving up for years for a new deck and Wlad and his crew were able to deliver. He offered different products and didnt try to push me towards the more expensive options and let me choose what I wanted. (we went with Trex but he gave us other options as well) He was always quick to respond whenever I had a question or wanted something changed because I wanted it to look a very specific way etc. He was here the day the materials were delivered to make sure they were put exactly where I wanted. He was very careful to make sure that my yard had the least amount of damage as I told him from the start that was one of my concerns. We now have an absolutely beautiful deck that will last longer than my home with the way it was constructed. I wanted it over built and they delivered. If I ever needed more work done in the future, Wlad would be the first guy I call. If you are looking for a great company to work with I highly recommend WS Builders!"

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