"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."

"We found Strong Builders by searching the internet and reading reviews. We feel very lucky to have connected with Jack to discuss our rather complex home renovation project, including adding a master bedroom above the garage, connecting the upper level to the existing house, and a large addition off the back. Jack worked with us to come up with a design that met our vision and provided a very detailed work plan that gave us a clear understanding of the timeline, cost, and overall scope of the project. This made it very transparent when we decided to add extras or to exclude some options. Jack is a professional. He takes pride in his work and valued our time. He was on the job personally each day working or supervising any sub-contracting work that was necessary and the project was completed on-time and on budget. We would not hesitate to recommend Jack for any project large or small and are so excited to be enjoying our â newâ home! Thanks Jack!"

"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."

"Ted built a 24x24 addition that involved dealing with Conservation over wetland issues. Quality work with attention to details and great design suggestions. I converted family room to garage and added mud room, laundry, bathroom and family room. Addition is beautiful. Would highly recommend."

"My house needed to be repaired from a huge fire. I was looking for a GC that has extensive knowledge of fire damage. After multiple quotes, I chose WS Builders because the owner was very professional and knew what he was talking about. Wladimir assisted me from beginning to end. We gutted the whole house and replace all the electricity. This was a big project and it was necessary to find a GC who had previous experience in rebuilding a house damaged by fire. I am very please with Wladimir's work ethic and professionalism. He had a quick turnaround and communicated thoroughly to ensure that I fully understand what was going on during the project. I recommend using him if you are looking for somebody with years of experience. Regardless of what job it is, he has the subcontractors to ensure the job is completed in a timely manner."

"We had last painted our house over 10 years ago and it was in dire need of carpentry work and exterior painting. I found it very easy to work with Real Painting from the start - they had solutions to all of our needs and the quote was detailed and easy to understand. The carpentry team was very skilled and their work exceeded my expectations for quality. The painting crew did an amazing job preparing the house for painting. They completely stripped the paint in most key areas and sanded the clapboards to perfection. Their attention to detail was immaculate - from caulking all to way to the finishing touches with our two-tone paint scheme. They also kept the site very clean. Everyone on the team was friendly, easy to talk to, and always showed that they cared for me as the customer. I am very happy with the work from Real - they delivered a great product at a reasonable price and within the expected timeframe."

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