  Knockout Renovation was the GC on a gut renovation apartment combination project in Chelsea that our office designed. They were extremely professional, and their craft was high level. The subs on the project were all very skilled. I would recommend them for any renovation project.

  I highly recommend for any construction needs! They recently completed a project for us, and the results are outstanding. The team was highly professional, always arrived on time, and kept the job site clean every day. The staff was very friendly and communicated clearly throughout the entire process, and the project was finished right on schedule and within our agreed budget. The attention to detail and workmanship are amazing. I will absolutely hire them again for future projects! I am very happy with their work and would recommend them to others.

  Please be warned. If you value your safety and your home, stay far away from this company. We hired Knockout Renovation for a sauna and bathroom remodel, and the results were dangerously bad. We brought in an independent sauna expert after seeing major issues, and he immediately said everything had been done wrong and that the sauna was unsafe to use. He literally laughed at the workmanship and called it one of the worst, most serious mistakes he’d seen in sauna construction. The craftsmanship throughout was careless and unsafe. We had to intervene repeatedly to stop Knockout from making more mistakes. Even the project management was so bad we eventually had to hire an independent project manager to manage Knockout’s own team. Even basics like a so-called “construction cleaning” consisted of one person showing up with no supplies (actually, they had one single rag lol); we had to spend hours cleaning and later hire a hauler to remove leftover debris. We’ve paused the project and engaged legal counsel. The sauna must be completely rebuilt from scratch to meet even basic safety standards.

  Update: This month I had to request NYC DOB to update Knockout Renovation's 6-year open permits fro replace a deceased electrician, so that we can proceed with inspections some 6-years later. They failed to close NYC Department of Buildings permits for plumbing and electrical work, leaving them open for six years. Despite paying six figures, I have had to personally intervene to resolve these issues, including removing a deceased electrical sub-contractor from the permits as I did this month. This dereliction by this company in handling permits has resulted in major inconvenience and significant financial burden. ************************************* Knockout Renovation promises a full-service experience, including permits and a 7-year warranty. My experience was the opposite: a nightmare of non-compliance and broken promises. This GC mismanaged our gut renovation from the start. They failed to secure proper NYC DOB permits and inspections, leaving our apartment in non-compliance for five years until our building stepped in. This dereliction prevented a Certificate of Occupancy and forced us to spend thousands on remediation, including hiring an NYC DOB Expeditor. Knockout Renovation agreed to cover these costs but paid only 15%, leaving us with a set $25K bill! Their "7-year labor AND product warranty" is a sham. They refuse to honor major issues, only minor cosmetic fixes. I was stuck paying $1,150 for a plumbing/stone leak they couldn't fix and would not reimburse me.. Knockout Renovation is irresponsible. They stiffed us for thousands and showed a shocking disregard for compliance and their own commitments. Avoid, especially if you're elderly and can't afford their financial snafus.
