"Hired Casieri construction to build decks and a carport as part of a new construction project. James and his crew do a great job and he is very responsive and timely. I would highly recommend them for any projects!"

Customers say: True professional

"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!"

"We hired Redman to completely gut our kitchen and dining room and make them one room. All new cabinets, island, windows, floors etc. it was such a smooth process and the finished product looked like it came off a magazine cover. We were so pleased that we hired them again to remove our entire second floor and turn our cape style house into a garrison style. The transformation was incredible. We added a second floor laundry, bathroom, Master bath, guest room/office and attic. I would not only recommend them to anyone needing work I would hire them again in a heartbeat."

"I hired US ProPaint and Renovation after meeting JR, discussing my project, and receiving what I thought was a fair and thorough proposal describing the work to be completed in 2 bathrooms. The team that worked in my home was professional, and they arrived on time each day. They were very careful to clean up after themselves each day. JR and his team also made sure, for each key piece of the project, that products were installed as I wanted them and that I was pleased with their progress. The team removed a vanity and granite countertops, installed a new bathroom vanity, installed LVT flooring in 2 bathrooms with transitions to meet the existing wood floors, installed new toilets, and then painted ceilings, doors, trim, and walls. The entire process was excellent and the best experience I’ve had with a company doing renovation work in my home. I’d use US ProPaint again and have recommended them to others."

"Highly recommended. Jose and Cesar were great. They were reliable and their work was excellent. They completely remodeled our condo including 4 bathrooms, floors, fireplace/hearth, etc. It was a big job and they worked with us to make sure everything came out exactly the way we wanted. The cost was very reasonable."

"I recently hired LionHeart Finish Carpentry for a bathroom remodel, and I honestly couldn?t be happier with the results. The entire process was smooth from start to finish. They were professional, punctual, respectful, and paid close attention to every detail. The quality of the work truly surprised me ? the bathroom came out even better than I expected. Everything looks clean, modern, and very well finished. They communicated well throughout the project and made sure everything was done the right way. It?s hard to find contractors who combine quality, professionalism, and reliability like this. I would definitely hire them again and highly recommend them to anyone looking for remodeling or finish carpentry work."

"My place of business has a minor water leak that needed repair and siding. The back area had major structural water damage from previous rains and would leak when it rained. The siding was removed, the rotted wood was exposed, cut out and replaced. Along with proper sealing and water proofing, painting and re siding. Business was able to remain open and consideration was taken. The clean up was more than excellent and proficient. Not a single nail or scrap was left behind. I would highly recommend for any home or business carpentry."

"We are trying to sell our house and are on a strict timeline. Max responded to my inquiry immediately and was very professional. He was able to come to our house the next day, and start the work within 48 hours of our inquiry. Him and his team were efficient, and gave us peace of mind going into the selling of our house. Could not recommend Makyson Building more!"

"To be fully honest, at first I was a little skeptical, as I am with most contractors, but they came in on time, were very clean, and were punctual about the things I asked for and needed done. The crew was efficient and the work was done correctly. They even helped and built my elderly neighbor a garage bathroom after seeing the work at my house. I definitely will have them back to build my ADU for my in-laws."

"Hired David Pierre, his crew and sub-contractors to install a new bathroom, remodel an existing bathroom, convert an attic to living space, install spray insulation, and rewire our 180 year old house in Plymouth, Ma. David impressed me with his professionalism and straight-forward approach, and I was not disappointed. Honest and committed to the end. Construction jobs always seem to take longer than expected, and this was true here, as well, but I think it is due to the nature of the business -- coordinating the schedules of several subs and dealing with unanticipated issues, especially when working on an old house. David juggled it all well. His core carpentry crew, Paul and Derek, were skilled, dedicated and responsive to requests. They kept the ball rolling forward. Good quality work at reasonable prices -- it would have cost me substantially more to use one of the larger home remodeling firms and I probably would get far less top-level attention."

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