"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."

"MMP was fantastic. They were easy to work with and did great work. We only had trouble with 2 sub-contractors during this project (Granite & Kitchen design) and they were the sub-contractors that my wife and I selected ourselves outside of MMP... we wish we had used MMP for everything because they did such a good job. I can't recommend them enough. We'd definitely use them again in the future and recommend them to anyone."

"Ryan and crew were awesome... professional, punctual, excellent workmanship, very fair price. Ryan and Warely did exactly what they said, exactly when they said it would be done. Excellent communications throughout the entire process. Will not hesitate to use Norman Construction again - and very happy to provide high recommendation! Norman Construction built two small-ish additions to our home (at the same time!) - the crew was able to perform some very detailed demo immediately adjacent to our living space to get the work completed .... with zero interruptions or issues to our living space."

"Crew arrived Friday morning, got right to work, and finished about 1/2 the job before quitting time. They were back after the weekend and finished the job mid afternoon. The workers were polite, cleaned up after work completely, and they and the owner had outstanding communication and customer service skills. We were impressed with their work ethic and professionalism, as well as the solid and attractive construction of our new steps and landing. We would definitely hire this company in the future.

"Our existing bathroom was a half bathroom with sink vanity, toilet, washer and dryer. We needed to eliminate laundry equipment and add shower and closet in the space that was designated for a washer and dryer, and add outside venting. We also wanted to tile the whole bathroom up to the ceiling. The job was performed excellent and we are very happy with the choices we made. Bill Perry and his crew were working in our house before renovating basement and building rooms there, so we knew that they were the best company for us. They were great giving us advice to improve on things that we wanted done, so they look and work better with a given space. We are very happy again. Thank you Perry Brothers!"

"We worked primarily with James to have a skylight installed in our recently constructed bathroom, as well as replacing an existing window in a bedroom, and adding a storm door. He was prompt and communicative, and very diligent about ensuring the space was clean and tidy after the work was completed. We are very happy with the installation of the windows and storm door and would recommend!"

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

"Great value, nice-clean work, Joshua was honest, reliable and started the job ahead of schedule. As a general contractor myself, I will be using these guys again. The work was brick repair, concrete, stairs, retaining walls, foundation repair. Finish product was exactly what I was looking for. Glad I found Sublime when I did. Great job guys!"

"Sean and his crew are truly Professionals within this Industry. Courteous, Friendly, Responsive and produce Excellent Quality Workmanship. By far, Sean and his crew are the best I have ever had the opportunity to hire for a major construction project that resulted in a comfort level knowing that everything was being handled properly. Construction is a challenging venture when putting on an Addition to an existing dwelling. There are many obstacles and challenges that can be faced throughout the project and within the home. Sean and his Team went over and above and addressed each challenge professionally and with timely resolution. I couldn't ask for any better service and results! The addition came out beautiful, I have an awesome Garage and my Wife is ecstatic with her new Mud Room and Pantry! I would recommend Hand and Some for any project that you may need."

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