"We did an almost-gut renovation of the top floor apartment of a brownstone building in Cobble Hill, Brooklyn. Scott Chatel was not the only contractor we solicited, but his vision of the job and his pricing were the most realistic. Scott is very easy to deal with. He was available for consultation both during and outside regular business hours. While he had several jobs going at once, his son Paul was in charge of our renovation, and one or the other of them was always available to discuss the construction and to answer questions. Scott did not let little glitches get in the way, and he took care of minor problems without extra charge. For example, we needed to move everything out of the apartment for the renovation, and on the start date we still needed to get rid of some furniture items. Scott's demolition guys took care of moving everything out. We had a tight 10-week schedule to make, and Scott was sensitive to getting the job done as scheduled. Scott met with us to schedule the timing for when different items (bathroom fixtures, appliances, etc.) needed to arrive both so they'd be available when needed, and also to make sure they were not in the way too early. It is impossible to anticipate everything that can crop up during a project, and Scott was flexible in dealing with the smaller issues and accommodating in dealing with the larger ones. The major unforeseen issue we faced was that our subfloor was in worse shape than anticipated, and needed to be rebuilt before the new floor could be laid on top. Despite the extra work, Scott stuck to the overall schedule to finish on time. Scott was helpful with design suggestions, such as adding a small soffit over some of the kitchen cabinets and creating a bar area by building some shelves in a corner. Scott's electrical, plumbing, and tile subcontractors all did good work. (Initially the tile work in the master bath was not up to snuff, but Scott had the tile contractor return, and he did an excellent job fixing everything.) Scott made sure to clean up the work area and the entire building's hallways that got dusty from the work. Scott returned at a mutually convenient time to take care of everything on our "punch list," and we anticipate one more visit (a full year later) to handle one or two smaller items that have cropped up. In a century-old brownstone, no corner is exactly square, and no surface is perfectly level. Scott's crew did a skillful and professional job of working with the building's quirks to make the work look right. We are very happy with the quality of the workmanship. He built closets to our specifications; he fit a bathtub into an area that previously held an oversize stall shower; he fit recessed lighting around existing skylights. Overall, we think we received great value: very good work at a fair price. We think Scott is a gem."

"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."

"After several estimates and meeting with multiple contractors, we decided to move forward with this team and we do not regret it! They were thorough with the estimate, helpful with financing, and offered their recommendations on styles but weren't pushy. This experience was entirely catered to us and we genuinely felt taken care of. The project itself took longer than we expected, but the team did find some structural damage that needed fixing and, of course, any renovation typically takes longer than estimated due to unforeseen circumstances. The guys working on the house were respectful, clean and friendly, and were even great with our two dogs so that I never had to worry about anything. I felt totally comfortable with them being in our home every day. Roberto and Steven were incredible, and if you have a chance to request them, do it! They helped me understand every single thing they were working on and kept in constant communication. Not to mention, the work is clean and super well done! At the end of our project there was a mishap where someone forgot to put an appliance hose back in the drain pipe which caused our basement to get some water, but the guys came right back to the house and cleaned/fixed everything as if it had never happened. All in all, we would definitely use this team again and we are so grateful to have our dream kitchen."

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