Without a good relationship, success becomes an opaque target. We focus on getting to know you and your project, well before beginning. We are happy to work with you to define the scope, budget and timeline of your project. Before we get started, you should feel you understand what to expect and when. You should understand what the project will cost and when that money is due. And if we truly succeed, you should feel that you got incredible value for your money. We are a small crew of honest and hard working people. We are good at what we do and we value our customers. No question is too dumb and it's never too late to ask question or make changes. This is your project, your home or business, and we want you to be thrilled with what we do.

"The New Story Carpentry team is an honest, knowledgable, and talented group that delivers very high quality work. Highly recommend! We hired NSC on a new construction build to manage a whole slew of interior framing and detail carpentry work. They jumped right in without missing a beat and adapted seamlessly when we asked them to increase their scope. Their pricing was fair, they were super reliable, and end result was great. "

FAQs for addition to existing structure building service projects in Winthrop, ME

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.
