"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!"

"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."

"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!"

"I recently had a home built for me in Kennebunk,Maine by Jason and the crew of Mason Sky Enterprises and I have nothing but praise for them, not only did they construct my home to the highest standards in an incredibly timely manner but they were also kind and considerate and endlessly patient when it came to my plethora of never ending questions which I am very grateful for. I highly recommend them for any job whether that be large or small. With much gratitude! SSgt.K Campbell USAF (Ret.)"

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