Keystone Contracting Corp

"Do not hire this contractor. We have called him on many occasions to come and fix the horrible job they did. It’s only been a few years and my stairs are all ready crumbling. They do not listen to the type of work you want and took advantage of an 83 years old woman. They got away with it because no one from her family was watching their work. Sloppy beyond belief. Cracks everywhere and mind you this was a brand new stairway, which is not even leveled correctly, and sidewalk replacement and entrance area into the ground floor They never even bothered to show me the concrete testing reports, they never even took sample for testing. We told them that we weren’t ready for the sidewalk for we were waiting for con Edison to do a gas conversion and what do they do, start destroying our sidewalk and we had no choice but to let them pour cement or we would have been fined by the city. They are such sneaky creeps. It’s just such an ugly job they even use old cobblestone. horrible job. They didn’t even put the right type of sand in-between the cobblestone it’s always dirty and cobblestone is too spread apart. When it rains it rains inside of the stairs. The outside of the stairs even has a white line that shows that the cinderblocks will be exposed soon So disgusted with their work so again, I would really consider not hiring them. old cobblestone used. Never any luster at all. It’s just such an ugly horrible job. Not even the right mortar/sand used it’s always looks dirty even when it’s wet. All they care about is a good review. Not with us. Come and see our home before you hire them, believe me you’ll run really quick. You definitely will think twice. I wish someone would have warned us!!!! No such luck. they have ignored our phone calls for months. I will write this review everyday until they come back and make it right. If not I will do my best to make sure they never work again if I can. I truly hate that they have gotten away with this. they even put in a drain where it didn’t belong did whatever they wanted we even hate the fact that under the stairs is retaining water and it’s just a matter of time before the cinderblocks are gonna burst. They didn’t even put any weep holes to absorb and flush out the water from the side of the stairs. So much water buildup it’s starting to create mildew. Again I’ve have called them numerous times and when I have spoke to him, he calls me is his friend. He’s no friend of ours. He wanted to make sure I gave him a good review. He doesn’t deserved not 1 star. AGAIN I cannot stress it enough DO NOT EVER HIRE this contractor"

"I was very pleased with the work that Keystone contracting did on my sidewalk. Frank and his crew are hard-working, honest, fair, and very good at what they do. I would highly recommend Keystone to anyone who is looking for concrete work sidewalk repair or just any contracting job in general."

"Choosing Keystone for our sidewalk repair was a decision we’re grateful for. From start to finish, their service was exemplary. Not only were they quick to respond to our inquiry, but they also provided a professional and thorough assessment of the work needed. It took only 9 days from our first email inquiry until the project was completed, including their team obtaining a DOT permit. Their team arrived on time and completed the repairs efficiently, cleanly, and with precision, demonstrating their expertise. What impressed us the most was their commitment to delivering high-quality results while maintaining affordability. In today’s market, finding a contractor who combines professionalism with cost-effectiveness is rare, but Keystone exceeded our expectations on both fronts. Overall, we couldn’t be happier with the outcome of our sidewalk repair project. Thanks to Keystone, our sidewalk not only looks fantastic but also passed DOT inspection. We highly recommend their services to anyone in need of top-notch construction work coupled with exceptional customer service—-CW"

"Would highly recommend! Keystone Contracting is a great construction company in NYC. Very fast and professional work. It was hard to find good construction contractors who would communicate clearly and answer all questions. They deliver quality work on time. Will hire again in future for more jobs."

"This company installed a new driveway at my house recently and I could not be more pleased with the work they performed. With their courteous and professional attitude, the entire process was completely hassle free... AND the price was right! Will use them again for sure."
