"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."

"The workers came on the appointed day with a longer ladder, as suggested.    Terry called to ask if he and an assistant could come by earlier than the original appointment time because they had finished work scheduled in the area earlier than expected; that certainly worked for me.    He surveyed the roof, took pictures and reattached a loose shingle that had fallen into the gutter.   Terry showed me the pictures of the roof from many angles; they showed no other repairs were necessary at this time.  Terry asked if there was anything else that required attention, but nothing else was immediately apparent.  He gave me his card and explained that the company does general contacting work.  
I am very impressed with the speed and efficiency shown today and won't hesitate to call MMP Construction in future if I need general contracting work done.

"Joe and his team did an excellent job with our basement! Joe is very responsive, managed all parts of the project very well, including permitting, solving new issues that came up unexpectedly, responding to inspector needs, addressing our additions to the projects, and trying his best to meet all our timelines. Even if things got delayed in some parts, it was very helpful that Joe was always able to communicate and keep us posted on where things stand. The pricing was fair, and I could trust Joe to provide good advice on the right services and materials to use. I recommend Joe for any home project and would be happy to use Silmac services again."

"We recently completed a kitchen and bathroom renovation and are very pleased. Having previously practiced construction law, I was particularly impressed with Eric's communication skills, responsiveness, and willingness to answer any and all questions we had without getting defensive. I think that is a rare quality in the construction profession. His crew Mike and Dave always were pleasant and friendly with my kids and me in the mornings and were incredibly hard workers - working through that awful heat wave in mid June and finishing the job on time."

"Any construction can be stressful, but with Liam and his team I was in good hands. I had some upgrades to one bathroom and a tub to shower conversion in the master bathroom. Liam was clearly very knowledgeable, and his workmanship in both bathrooms was impeccable. He answered all my questions, had great suggestions and was very responsive whenever I needed to contact him. The demo in the master was completed in a day, and the guys cleared everything after they finished. The tile work was meticulous and just beautiful. I highly recommend Liam Neary Construction."

"Other builders came in with estimates that cost less than US ProPaint and Renovation. In spite of this we chose US ProPaint and Renovation because JR explained all the work that would be done to demolish our wooden deck and replace it with trex decking. The other builders who gave us estimates did not spend as much time, or explain what they would do to complete the work we wanted.; and their estimates were lower in cost, but not a whole lot less. Once we committed to have US ProPaint and Renovation work for us, the work began very quickly. JR told us the work would commence in 2 weeks. They actually started earlier than that. 3 men worked long hours, typically 8:30 am to 7 pm each day in some pretty warm and humid weather. They were courteous and kept me informed on what they were going to accomplish on any given day. We were completely satisfied with the work and how the deck ended up. We will hire them again for other projects."

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

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