We are Brooklyn's trusted basement remodeling contractor, serving Bay Ridge, Dyker Heights, Bensonhurst, Borough Park, Sunset Park, and surrounding neighborhoods. With over 15 years of licensed experience across Brooklyn, our team delivers quality craftsmanship, clean job sites, and results you will be proud of.
Your basement is probably the most underused space in your home.
Most Brooklyn basements become storage by default — not because that is what anyone planned, but because no one took the time to think about what they could become. A finished basement adds real living space, real value, and real functionality to your home.
Whether you want a family room, a home office, a guest suite, or an entertainment space, we will help you plan it and build it right. We handle everything from waterproofing and structural work through final finishes.
We have been doing this in Brooklyn for more than 15 years.
Services
Full Basement Renovation
We manage the entire basement renovation from start to finish — waterproofing, framing, electrical, flooring, and final finishes. Every project includes proper NYC permits and a dedicated crew that stays with your project from day one to final walkthrough.
"Landi and his team are highly professional and efficient. They provided the right mix of value and quality for our project. Extremely communicative, punctual and diligent. They completed our project on time, on budget and it looks great." — Trevor Martin
Basement Waterproofing
A dry basement is the foundation of everything else. Before any finishing work begins, we make sure your basement is properly waterproofed and protected against moisture damage. It is not the glamorous part — but it is what makes everything else last.
"Everything was done with incredible care and craftsmanship. The quality of the work exceeded our expectations across the board." — Ravi Solter
Flooring Installation
We install tile, hardwood, and luxury vinyl flooring in basements throughout Brooklyn. Our team selects materials suited for below-grade spaces and installs them with the same precision we bring to every project.
"The attention to detail was excellent and the finished floors look absolutely beautiful. The entire process was smooth and professional from start to finish." — Irida Llambiri
Painting & Finishing
The finishing touches are what turn a renovation into a room you are proud of. We handle plastering, painting, trim work, and all final details to make sure your basement looks and feels like a real part of your home.
"They patched and painted the entire house. Everything was done well and very quickly. Landi is a great communicator and very trustworthy." — Seth Rosner

FAQs
Do I need a permit for a basement remodel in Brooklyn?
Most basement renovations require permits — especially if you are adding electrical, plumbing, or making structural changes. As a licensed contractor, Zani Construction NYC handles all permit applications with the NYC Department of Buildings on your behalf.
How long does a basement remodel take in Brooklyn?
A basic basement finish typically takes three to five weeks. A full gut renovation with new electrical, plumbing, and finishes generally runs six to ten weeks depending on scope, material lead times, and permit timelines. We give every client a detailed timeline before work begins and we stick to it.
Are you licensed and insured to work in NYC?
Yes. Zani Construction NYC holds an active NYC Home Improvement Contractor license and carries full general liability and workers' compensation insurance. We are also BBB accredited and members of the Brooklyn Chamber of Commerce. Documentation is available upon request.
Do you handle design as well as construction?
Yes. We work with you from the design phase through to the final reveal. We help you think through the layout, materials, and finishes so the space works the way you want it to. If you already have a designer you are working with, we are happy to collaborate.
Can you finish a basement in a Brooklyn brownstone or co-op?
Yes. We are experienced working within the requirements of Brooklyn brownstones, co-ops, and condos. We handle alteration agreements, insurance certificates, and all coordination with building management so the process is as smooth as possible for you.
