"I have had Jeff and his guys renovate my ranch house in Melville. He has done 2 bathrooms, my basement and my kitchen. He has always been reliable and done great work. The house looks like new. He quickly corrects any problems and is always in touch. He and his guys are friendly and neat. His estimates are reasonable. I strongly recommend Northgate Home Improvement."

"We hired Stars and Stripes for a few projects around our home. The main one was our kitchen re-model. The project was done professionally, beautifully, and ON TIME! We would definitely recommend (and continue to use) Stars and Stripes. I?ve attached some before and after pics to see their work. "

"I hired CNM for a full gut renovation of my West Village apartment in NYC. The CNM team (Matt, Jose, Mateo & Vicente) are a tremendous group to work with. They provided top notch customer service and excellent craftsmanship and attention to detail. They would be my #1 recommendation to anyone looking for a General Contractor. 10 out of 10 experience."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"After the toilet was changed on 9/1/23. The plumber refused to caulk the gap at the base of the new toilet. Gaudioso didn’t respond to my request to fix it. That left a gap and roaches were roaming out from that gap into my apartment for 11 days until I hired a handyman to caulk it. It costed me extra money and emotional distress"

"Inson is a creative genius with a superb eye. He did everything with meticulous detail and completely transformed our apartment into an amazing, gorgeous home. We enjoy entertaining, and our friends love coming over, always remarking how beautiful and inviting our home is- and that was exactly what we wanted, except Inson brilliantly upgraded our concept, within budget and on time (even with our aggressive timeline because we needed to be out of our old place and into our new within months!). Inson’s team was also great to work with - always polite and professional. We highly recommend Inson and plan on working with him again on our Hamptons home!"

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