"I had the pleasure of working with Dave for my kitchen renovation. From start to finish, their attention to detail and craftsmanship were truly remarkable. The contractor displayed excellent communication skills, always keeping me informed about the progress and any changes that needed to be made. Not only did they complete the project on time, but they also exceeded my expectations in terms of quality. Every aspect of the kitchen, from the countertops to the cabinetry, was flawlessly executed. Additionally, Dave was highly professional and respectful throughout the entire process. They were always punctual and ensured that the work area was clean and organized at the end of each day. It was a pleasure having them in my home."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

Customers say: True professional

"Inson worked with us on our home in the Hamptons and house in San Francisco. He brings an extraordinary combination of very high end style personalized for our tastes; access to special deals from the most elite and sought after designers; and a sense of working within the budget you have in mind. We were able to get museum quality pieces for both homes at unbelieveable discounts. Inson also continues to provide important follow up services as needed. For example, we had a fabric issue with our 40 outdoor chairs that developed after the warranty. The cost to change would have been tens of thousands of dollars but the manufacturer handle the out of warranty issue at no cost to us, which I believe was due to inson’s relationship and advocacy on our behalf. He’s terrific."

"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."

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