"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."

"The Curtice Group finished our bathroom renovation in early April 2023. We can give a wholehearted positive review for Scott Curtice’s coordination of the project including keeping to and even improving upon the original schedule, cost transparency throughout, and thoughtful approaches to both design as well as any problems encountered. Scott was an excellent communicator all through the work, being both accessible and responsive to our concerns and questions. Proficient management of the timing of subcontractors by Scott and his project managers was key to the success of the process. All of the above contributed to a great result. The bathroom work included a complete change in the location of the original plumbing and an extension into another room. Scott designed a bathroom that fits our needs, which includes a lot of storage as well as a feeling of spaciousness in what is not really a big space. At the outset, he recommended vendors, always with the caveat that we could choose our own. He also accompanied us to a vendor for the main plumbing components of the bathroom. For access during the work, he created a temporary entrance that would allow access to the work site without going through the rest of the house. In addition to the bathroom, we changed multiple interior doors, replaced the original basement windows and door, changed multiple lighting fixtures and did additional carpentry work. We also addressed remedial plumbing problems in the basement as well as in another bathroom."

"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."

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."

"Pedro Quissanga was wonderful throughout the process. The project started out as a porch window replacement with an architect drawing plans, but once we started construction, we discovered that the whole underneath part was rotting and needed reconstruction. Pedro and his crew were hard working, reliable and careful, and his price for all of the work was very reasonable. When something went awry late in the construction, Pedro took it seriously and got people over within hours to locate the issue and fix the problem. Even though the project ended up being much more difficult than initially expected, there were never any unexpected charges and the additional work was at a consistent high level. We recommend Crystal Renovations without reservation and have several neighbors using them now for small-to-medium sized projects."

"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."

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