Cellar Door Installation
NYC Cellar Door Installation
Done Right the First Time
We install custom-fabricated cellar doors across all five NYC boroughs. Every installation is NYC DOB compliant and backed by our workmanship guarantee.
Why It Matters
A weak or damaged cellar door creates safety risks, water intrusion, security vulnerabilities, and liability exposure. A properly fabricated and installed steel door improves access, appearance, safety, and security — and keeps you code compliant with NYC DOB.
