"Eric's team rebuilt our entire three season room, which was not functional. It is now, thanks to Mike and Brian. It also looks very good! Mike works hard at getting things done, and teaches the younger crew very well. He is structured and trustworthy. He also was patient answering my questions (I always have too many..!). Brian pays great attention to detail! I was impressed by how good the tile work looks, and also how good the finishing of the decking to the landing looks like, which he did. They also had to partly redo the patio, and it looks better than before."

"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."

"
Antonio communicated clearly with me, every step of the construction process.  After removing the siding, there was additional water damage underneath that required additional work.  He carefully showed me and explained what had to be done, and we revised the scope of the work.  My husband and I felt that he showed a lot of honesty and integrity in carefully outlining and showing us additional work needed, that could not be seen until the siding was removed. We felt he was very fair with us in his pricing for the scope of the work.

He helped us review the composite siding options and warranties, and brought us samples for the siding and decking, at different price points and explained in detail differences between each. He and his crew came punctually and on the schedule that Antonio had laid out for us.  They were meticulous in their clean-up as well.

The quality of Antonio's work, as well as his careful product research and commitment to our satisfaction, totally surpassed our expectations.  We do not hesitate in recommending Antonio, and plan to have him renovate our bathroom in the Spring."

"Sanfer and subs did a great job on our house addition. Added a basement in law apt. Dug out and dug down. Family room, office above. Left a previous review but forgot to include electrical in the services. Thought Sanfer and subs did a nice job helping with decision making and installation. He had thoughtful suggestions that were experienced based. Appreciated that. Very pleased with outcome."

"Working with Jack Whealan means that you're working with the best. My family had a rather complicated project that included 3 major phases along with painting and refinishing existing floors. Not only did Jack complete the majority of the project independently, but he did so while seamlessly coordinating subcontractors to keep the process running smoothly. Jack kept us in the loop every step of the way, and delivered a product that is superior to any other project we've had done. Jack answered all of our questions around the clock, and made sure we had the information behind his answers. He provided great insight about so many things in the home (whether they dealt with the new build or not). You can tell that Jack is a person who genuinely cares about the work he is doing. He is meticulous and detail oriented, and he won't install something in your home that he wouldn't put in his own home. If I had to go back before this project was started and choose a contractor to work with, I can 100% say I wouldn't choose anyone but Jack. You seriously can't go wrong with Strong Builders. It was a pleasure to work with Jack and we are so happy with our new home."

"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."

"Kinsella Built was great! So good that we have recommended them to all of our friends (now that is a true testimonial of their work). Our job was significant. We put on an addition to the house, created an open concept inside and finished our basement. The entire job was 7 months. Yet each day they showed such work ethic; always showing up at 7AM and putting in a full day work. They were professional, created a very quality product, were reasonable and finished the job on time. You can't ask much more of that from a contractor. For all of our future construction products, we will be going with Kinsella. Thank you to James & John (and Ian, and crew) for their wonderful work. We love our "new" home!"

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