In 2016, J&S did a lot of work at the rear of our house in Throgs Neck. Granite terrace,…read morestairway...and stucco. Two years later, the stucco was beginning to de-laminate in three spots. In the spring of 2020, when the stucco was looking really terrible (bubbles, peeling, falling off, etc...see photos for examples), we asked John to come by and take a look. Of the roughly 450 square feet of stucco applied, about half is showing severe bubbling and peeling now. HE TOOK NO RESPONSIBILITY. It's water damage...that's not in dispute...but he blamed everything from the siding on the house to the stone terrace...which he installed. Since then, we've had two stucco experts inspect the damage, and they both immediately had the same verdict. The stucco was laid directly over the cinder block, with absolutely no water management / prevention in place. No mesh or styrofoam, no drip line cut into the granite lip above the stucco wall, nothing. Now we face a $4,000 repair job...for work done only FOUR years ago. Needless to say we'll be finding another company to do the work. In his online response, John will likely say that the vinyl siding of the house is causing water problems. So it's important to say here that NONE of the problem areas are anywhere near the siding. We're having water problems because, again, there was NO mesh or styrofoam placed between the cinder block and stucco, and there was no drip line added to the overhead granite lip...which they installed. NO EXCUSES. Avoid these guys, unless you want to pay twice.

I have a crawlspace extension in Queens that was built in the late 1980s by previous owner. In the…read morewinter time, it was noticeably colder in the extension. I reached out to Ramon to ask for his advice. He stopped by within 24 hours of our initial contact. He suggested that we insulate the foundation walls and install a vapor barrier. His price was reasonable and he was hired on the spot. The work started a few days later and it was done within a few hours. I noticed some concerns in the coming days so I reached out and he came back within a few days to rectify those concerns. 10 out of 10 would recommend for all your waterproofing jobs.

This company did an absolutely terrible job repairing the sidewalks for five houses on Johnson Ave…read morein the Bronx. At first, everything looked fine, but after the concrete had only about a week to settle and dry, the top layer already started peeling off. That should never happen with proper sidewalk work. When we raised the issue with Eden, the excuse we got was that salt used to melt snow must have caused the damage. I made it very clear that I did not apply salt, yet the concrete still began failing almost immediately. Even so, we gave them the benefit of the doubt and chose not to make a bigger issue out of it at the time. Now, one year later, the sidewalk is peeling horribly and looks awful. There is no reasonable excuse for concrete work to deteriorate this badly in such a short time. In my view, this reflects extremely poor workmanship and very questionable material quality. What makes the situation even worse is the company's complete lack of accountability. When we contacted them again to address the problem, we were met with either silence or outright denial. Once they have your money, they apparently want nothing to do with the consequences of their work. Based on my experience, I would strongly warn others to stay away from this company. The work did not hold up, the excuses were weak, and the customer service was unacceptable. There are far more honest, reliable, and professional companies in the Bronx and NYC. I would never use them again.
