We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumers needs. It is our mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"I was very lucky to find Colin Young and his great crew, carpenter David Hackett and his talented son, Andrew. We were taking down an old deck and adding a room to our house, along with doing a little kitchen remodeling. Dave and Andrew are excellent craftsmen. They also came up with creative solutions to some tricky design problems. Dave and Andrew always showed up on time, worked hard, then cleaned up the site at the end of the day. My step-father was a builder and I learned from him that there are right ways and wrong ways to do a job. Dave and Andrew did things the right way, and never cut corners. I highly recommend Green Island Homes. Also, I got 4 bids on this job and their price was very fair."

"We hired James, Dan, and their crew for a major deck renovation. The level of thoughtfulness and craftsmanship throughout the project was outstanding. This was not a simple refresh — it involved removing an existing hot tub, renovating a cabana, reworking the deck framing to convert it into a single-level deck, installing a new staircase, and adding a cable rail system. Every aspect of the project was approached with precision and care, and the finished product is without flaw. They were easy to work with from start to finish, handling decisions and mid-project modifications thoughtfully and professionally. The whole crew was consistently approachable and friendly, and clearly took pride in their work. Daily cleanup was always done well, which we especially appreciated since we had a puppy at the time. Definitely recommended!"

"I am extremely pleased with the work done by Pierre Construction! I needed a basement remodel completed for my teen who was away on a trip, it was meant to be a surprise for their birthday, and we only had 10days to make it happen. Despite the tight deadline, David assured me he could get it done, & he absolutely delivered. He provided a fair price upfront that remained consistent throughout the project. When unexpected issues came up that could have increased costs, David was transparent about the options and worked with me to stay within budget. His communication was clear & consistent from start to finish. The finished room turned out amazing, better than I could have imagined! I gave David creative control over the colors and layout, and his vision perfectly captured what I’d hoped for from our very first meeting. The attention to detail was truly five-star, & the entire process was stress free. I’ll definitely be using Pierre Construction for future projects. Highly recommended!"

FAQs for addition to existing structure building service projects in 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.
