"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."

"Mr. Powers, at first, was courteous and reliable; the project seemed to have problems, and he was getting frustrated at having to surface the existing deck due to its configuration; he claimed that the measurements and figures were off, while another professional disagreed with his calculations; the project was delayed due to materials being delayed by supplier; Mr. Powers suggested another other remedies for steps and that I purchase an additional type of board for $120, which I did; i paid Mr. Powers in full of the understanding that he would come back and finish off certain areas; during this time, a death occurred and he was unable to come when scheduled; when I texted Mr. Powers, he began belligerent, and cursed at me. I do not find it professional to curse at a client and refuse to take phone calls. I ultimately told Mr. Powers not to come back to my house and to refund the board I purchased that was in his possession. He did so. Since the time of completion, May 2026, numerous boards have come loose. I had someone else correct this issue, and now more boards are coming loose, which I texted him about and showed pictures of on September 9, 2026, and have not heard back from Mr. Powers regarding acknowledgment or addressing the loose boards, as my contract provides for two (2) years."

"I am extremely satisfied with the work done by Gary from CGP Construction. From the initial consultation to the final walk-through, Gary was trustworthy, professional, reliable, and transparent. The quote was fair/reasonable and accurately reflected the quality of work delivered, which far exceeded our expectations. Throughout the project, Gary was always available to answer questions and provide updates. The attention to detail and willingness to explain every step of the process made the entire experience stress-free. The end result far exceeded our expectations! I highly recommend Gary and CGP Construction for any home project. You won't be disappointed!"

"Jeff and his crew were amazing! If I could give them 10 stars I would. We needed a bathroom ceiling repair and an exhaust fan installed. Jeff suggested crown molding for around the entire bathroom and it came out gorgeous. Not only are they great at what they do but theyâ re professional, honest and so neat with their work. I was fearing a dusty mess and there was none. If youâ re looking for someone to do anything and everything, this is the company to hire!"

"Wow! I originally called Raquel at iRiverdale Construction to design my kitchen, and she ended up transforming three floors of my home! She is an amazing woman, and I cannot recommend her and her company enough. Raquel even accompanied me to vendors to help choose all the materials and worked around my very busy schedule. Her personal attention and dedication made the entire experience so special. Her team was fabulous?professional, talented, and a pleasure to work with. I wish I could buy five more houses just so Raquel could redesign them all! If you?re looking to transform your home, I wholeheartedly recommend iRiverdale Construction!"

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