Why It Matters
Renovating in Manhattan Is Different
Manhattan renovations require more than craftsmanship. They require careful planning around building rules, alteration agreements, insurance requirements, DOB coordination, delivery logistics, neighbor protection, work-hour restrictions, and board expectations.
A contractor who doesn’t understand these requirements can create delays, compliance issues, and unnecessary friction with building management. We plan for these realities before construction begins.
Plan Your Manhattan Renovation
Start with our Manhattan general contractor services and review documented work and client experiences to understand our approach.
Before defining the construction scope, explore NYC co-op renovation rules and the NYC renovation permit guide. Building review and agency requirements depend on the property and proposed work.
Use our Manhattan apartment renovation cost guide to organize scope, procurement and building logistics before requesting a project-specific estimate.

Reviews for Corniel Construction LLC
Leor
I’ve hired Corniel Construction for new flooring, drywall/painting, vanity installations, and miscellaneous repairs. I definitely recommend them.
Barry Neal
Corniel is amazing. I hired Corniel for a commercial office renovation restoration. Not only did they do a fantastic job, they finished with coordinated scheduling and closeout and on budget.
Alice Lewellen
We remodeled 3 bathrooms and Ruben was amazing. Everything we asked for, he made sure we were satisfied. Even when I changed my mind or asked for an additional thing, Waldy made it happen. We could easily contact him every day, and he always responded ASAP.Waldy is very experienced and knowledgeable, even offering helpful suggestions.
