"My wife and I were looking to have an addition built on our 2 bedroom / 1 bath home back in the winter of 2022. After a phone conversation with Richard, we decided to have him come out to the house. He was very clear with the iCornerstone process, and the benefits of using this process. He is meticulous in measuring and understanding the existing structure. There are no guesstimates and all cost projections are based on the actual materials and labor needed to complete the work. Having such clarity regarding costs before any work begins is not something I've seen in this industry prior to this experience. It was certainly a welcome change. We now have plans for a home addition and complete control over the project. We decide the scope and can customize the plan to our budget. We are grateful to have worked with Richard, and highly recommend him!"

"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."

"I hit the jackpot when I chose Bob Ayotte to build my accessory dwelling unit in my son's 2 car garage. I should have purchased a lottery ticket! He is honest, a perfectionist, neat and very knowledgeable! Most impressive for me was the fact that Bob took the time to listen and understand what I needed to make this dwelling my "forever place" now that I have retired."

"Derek was quick to respond and jump on remodeling our bathroom before officially moving in. As project continued he kept us up to date and pointed out issues with existing structure around floor and window. Within few months the bathroom remodel was complete. Bathroom is beautiful and James did great work on tile/shower area."

"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."

"From start to finish I had a great experience with Carlos and all of the guys that worked for him. I previously had a relationship with him because he was the Contracted Painting Company for the new house that we moved into (Feb 2017) so I knew from that experience that all of his staff had fantastic attention to detail. I spoke with him about my project unaware that he also did renovations and was impressed with his level of knowledge and timeliness in getting back to me with any questions. He was available throughout the project and tried to keep things moving as quickly as possible which is not always easy when you're relying on plumbers, electricians, carpenters etc. We had a few hiccups along the way, like any significant project has, but Carlos always acted as quickly as possible to get them resolved and never just added additional cost without first having a conversation with me. We went from a finished, but unused, space in the basement to now having our own bar that most pub landlords would be proud of! All of this staff were extremely knowledgeable and easy to deal with. I would definitely work with him again on any future projects."

"The CP construction crew were very hard working and competent. Clod as the owner is extremely customer service oriented. He communicated with me throughout the permitting process, the build and the inspection process. The new deck and stairs look great and bring compliments from all the neighbors. I will definitely reach out to CP construction in the future."

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