"First of all I am EXTREMELY fussy about any work done on our antique farm. That said, Vanni does a super job. The most meticulous carpenter I have ever worked with. Great attention to even the smallest detail. He is affable, prompt, honest, reliable and a true master of his trade. Furthermore he cleans up ALL mess before leaving each night. As stated we own an antique farmhouse with four barns/out buildings and consequently have dealt with a multitude of contractors over the years. He is the best carpenter by a long shot. If you want the best workmanship you need not shop around. Do yourself a favor and hire him."

"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."

"Rich and his team are just great to work with. When I had decided to finish a section of my basement, I had requested multiple quotes for an open ceiling idea approach that I had decided on. Rich came out listened to what I wanted and send me an itemized quote, even telling me that he needs to do some homework on the open ceiling approach. Others who had contacted, either lumped it all together, or even went as far as saying that the open ceiling idea was not doable due to code requirements. As the project processed, we decided to redo the stairs to the basement, which itself was old and not build right, and also change the basement windows that was built into the foundation of my 60 yr old. At each stage, Rich would keep me informed of what needs to be done, that he had verified with the building code inspector etc, and fill me in after doing his research to see how to accomplish what i wanted to do, even making suggestions along the way, while also paying attention to the budget. At every junction I felt he had the best outcome of the project in mind. What impressed me the most about Rich and his team was the attention to detail and also the creativity in handling the challenges that come with an open ceiling concept. The best reaction was from my 3 yr old, who saw the finished work and said it looked beautiful. I will gladly recommend Rich to anyone who has a substantial project to do."

"William and his crew did a good job of the laborious and complex task of removing and replacing a rotting, out of date, porch structure on my home. William walked me through every step of the way and maintained great communication throughout the project letting me know where they were in the project as well as any difficulties or complexities that they faced. William stood behind his work addressing any and all concerns I had when the job was finished. I never felt abandoned or isolated at any point of the project. I felt more included in this project than at any time while working with different contractors. Overall, I highly recommend William. He proven himself to me as someone who is not only capable but someone is motivated and passionate in completing and renovating homes or structures. I will be using William and his crew in the future. I know for a fact I have gained a vital resource for any more work needed to be done in my home."

"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."

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