"WR Builders Inc. is an excellent construction company that provides high-quality workmanship. We hired them for an addition to our home, and they did an outstanding job. They were punctual, professional, and took the time to explain each step of the process. The addition blends perfectly with the existing structure, and we are very pleased with their work."

"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."

"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."

"DiOrio builders did excellent basement work. Before DiOrio- my basement unusable, a dusty mess, the walls and ceiling peeling so bad, I couldn’t even walk in there without being covered in chalk. Quotes from other contractors were outrageously high, with a bunch of complicated add-ons. DiOrio builders found a solution at a price that made sense, they fixed exactly what needed fixing. They demolished the old structures, scraped the walls and ceiling, removed decades-old debris, sealed the foundation and put a bright white coating on the wall. Plus, once they removed all the debris, the air quality is much better in the upstairs of my house! I’m so happy they made my basement useable, and I will definitely be calling DiOrio Builders and Designers when it’s time to build a lounge down there."

"Working with Jack Whealan means that you're working with the best. My family had a rather complicated project that included 3 major phases along with painting and refinishing existing floors. Not only did Jack complete the majority of the project independently, but he did so while seamlessly coordinating subcontractors to keep the process running smoothly. Jack kept us in the loop every step of the way, and delivered a product that is superior to any other project we've had done. Jack answered all of our questions around the clock, and made sure we had the information behind his answers. He provided great insight about so many things in the home (whether they dealt with the new build or not). You can tell that Jack is a person who genuinely cares about the work he is doing. He is meticulous and detail oriented, and he won't install something in your home that he wouldn't put in his own home. If I had to go back before this project was started and choose a contractor to work with, I can 100% say I wouldn't choose anyone but Jack. You seriously can't go wrong with Strong Builders. It was a pleasure to work with Jack and we are so happy with our new home."

"Liam and Kevin were incredible professional and finished the job in record time! We were on a very tight timeline and they made themselves available to start and finish the project before our store opened. They had great suggestions and knowledge on what we could and could not do with the space structurally, and we could not be happier with the end results from Neary Construction! I'd recommend Liam and his team for any size project, and will be using them for any other construction needs - they did an incredible job!"

"Overall we were thrilled with how our project came out. Mike and his team proved highly collaborative and skilled in their respective trades while also involving us as active partners in design and construction choices. Being able to work with both Ivan during the design phase and then Mike during construction to make sure our design and budget needs were met proved invaluable throughout the year long process. Mike was always willing to hop on the phone to talk through design decisions or product selection as we were deciding on finishes throughout the process. He also was more than willing to discuss scope changes and refining of the original build plans as we saw those plans turn into reality. Overall we will definitely be calling Mike and team for any future needs. We would highly recommend for those looking for a full service contracting team."

"John is the best! We obtained 3-4 quotes for our full bathroom remodel. Everyone else estimated 6+ weeks to remodel the bathroom - which is our only shower. John promised he would have it done in 2 weeks. It was fully complete in 13 days! This was a total remodel down to the studs. Great work, super fast, super responsive, and his cost was right in the middle of the estimates we received. This was in Nov. 2019. Since then we have had John's team back on a number of projects: to replace our fireplace mantle and staircase, and repaint our first floor. He also installed new pantry cabinets in our kitchen and new flooring in our basement. John is now our go to guy for all our home repair needs. He's great - can't recommend high enough!"

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