"Nice owner, hack job crew. Hired to replace siding and trim. Manager of the project was fired a few times during work and it really shows. So many small details are either unfinished or poorly done. Amateur cuts on the trim left gaps and old trim was not prep for paint or just left unpainted. They also smeared silicone to cover screws on the front face of the shingles, the whole house looks like it's covered in bird droppings. Plus they also damaged the roof and electrical boxes. Who knows what other things they skipped on, left me with a time bomb of problems that will takes years to show. I would not recommend. "

General contracting with an emphasis on new homes, additions, garages, in-law apartments (ADU), custom decks.

"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!"

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