"Fine Design did a great job on our bathroom from the gutting to the finish. Dave and Lenny were easy to work with and the workers were great! Cleaned everything up each day and were very polite. The quality of the work is outstanding. Everyone was very professional and was a much more pleasant experience compared to other contractors I have used. Thanks again-I highly recommend Fine Design."

"Paul, Gene and their teams were delightful to work with. They're a busy company but managed to be on time, respond to our questions and felt accessible throughout the project. The members of the different crews were polite, professional and always on time. As with any project, there was a small issue that we wanted adjusted, and no problem at all. It was taken care of immediately. They were able to make suggestions without being aggressive and we welcomed their input. I only wish we had additional funding to do a few more projects! I am pleased to recommend this company without hesitation."

FAQs for addition to existing structure building service projects in Lynbrook, NY

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.
