"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!"

"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!"

"Every aspect of this project, from planning and architectural work to contractors, sub contractors and coordination was 100%. I received a spreadsheet every week with expenses as compared to budget including all materials and labor. Each step of the project including consultations, advice for saving $$ as well as suggestions for improvements in existing HVAC systems were valuable. All contractors were 100% reliable, professional, were creative and constructive in addressing challenges that emerge in any project and demonstrated outstanding follow through. The shop is extremely comfortable even on the coldest days and maintains even humidity for the wood. The project was on budget, on time and exceeded expectations, particularly with regard to workmanship, communication and professionalism."

"I would highly recommend MMP Construction. Matt and his team are knowledgeable, friendly, and extremely hardworking. Even after running into some unexpected structural issues once the walls were opened up they still managed to get the job done in the time frame quoted by working extra hours and weekends. I was truly blown away by the level of dedication and service. Anytime a challenge came up, someone on the team was quick to provide a great solution. And the finished product is absolutely gorgeous. I would hire them again in a heartbeat. <br />"

"3 G construction did an excellent job on replacing our bathroom ceiling. They were very prompt, professional and kept us informed on the time frame and finished everything in the time he said it would take for the project to be done. I'm so glad that we hired Richard and his team to handle the project. I will definitely use them again. Thank you"

"Humberto and his team were terrific! They refinished the walls in 3 rooms of our house and their work was top notch. They removed wallpaper, sanded, plastered and painted our walls so that now they look pristine. I asked them if they could put in new doors and they did a great job with that too. I would refer this team to friends and family and will be using them again for other projects."

"Any construction can be stressful, but with Liam and his team I was in good hands. I had some upgrades to one bathroom and a tub to shower conversion in the master bathroom. Liam was clearly very knowledgeable, and his workmanship in both bathrooms was impeccable. He answered all my questions, had great suggestions and was very responsive whenever I needed to contact him. The demo in the master was completed in a day, and the guys cleared everything after they finished. The tile work was meticulous and just beautiful. I highly recommend Liam Neary Construction."

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