With over 25 years experience, family owned and operated. We are a home improvement contractor that pride ourselves on being available for our customers, standing behind our product, service and labor. Focusing on kitchen and bathroom remodeling in the New York City and Brooklyn area working on brownstone homes and apartment renovations.

"Mark took a deposit from me and then never followed up on submitting the proposal I signed to my co-op and getting approval. Finally almost a year later, I asked for the deposit back, and he said he would mail immediately after briefly trying to convince me to still let him do the job, because it was simply "out of sight out of mind". That was 2 years ago. I'm filing a small claims case against him/the company tomorrow."

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