Liberty Door Supply is a commercial glass and aluminum storefront contractor serving Brooklyn property managers, general contractors, retail owners, and building owners. We supply, fabricate, and install storefront glass systems, aluminum doors, ADA automatic entries, rolling security gates, panic hardware, and glass partitions. We also cover emergency board-up and glass replacement when a door or window takes damage. Brooklyn is a core part of our service territory, and we work across every neighborhood from Williamsburg and Bushwick to Bay Ridge, Flatbush, Crown Heights, Sunset Park, and beyond.
What kinds of commercial buildings and projects does Liberty Door Supply handle in Brooklyn?
Brooklyn's building stock is diverse. You have older masonry retail corridors along Atlantic Avenue, Fulton Street, and Flatbush Avenue. You have ground-floor retail in new mixed-use residential towers in Williamsburg and Downtown Brooklyn. You have industrial-to-commercial conversions in Bushwick and Red Hook. Each building type presents different framing, structural, and code requirements.
Common Brooklyn projects we handle include:
- Storefront glass and aluminum door replacement in existing masonry openings, using Kawneer 350 or YKK AP 450T framing systems
- Full storefront system installations on new construction or gut renovations, with thermally broken aluminum framing for energy code compliance
- Curtain wall and glass facade work on mixed-use and commercial buildings, using Oldcastle BuildingEnvelope and Kawneer 1600 curtain wall systems
- Rolling security gate installation and replacement, including slat steel and perforated steel gates with manual or motor-operated operators
- Glass partition and railing systems for interior commercial buildouts, using 1/2-inch or 3/4-inch tempered or laminated glass in aluminum channels
- Emergency board-up and glass replacement after break-ins, accidents, or storm damage
We file with the New York City Department of Buildings when permits are required, and we build to NYC building code and ADA standards on every project.
How does Liberty Door Supply approach ADA compliance and automatic entry installation in Brooklyn storefronts?
ADA compliance is not optional for commercial properties open to the public. Brooklyn has a large number of older retail storefronts that were built before modern accessibility standards. Many of these buildings are now going through renovations or change-of-use projects that trigger ADA upgrade requirements.
We install low-energy automatic door operators from LCN and Dorma Kaba, paired with ADA-compliant aluminum door frames and the correct clear-width openings. For high-traffic entries, we use Stanley Access Technologies full-energy swing and sliding operators. Activation can be handled with push-plate buttons mounted at ADA-compliant heights. This is mechanical activation, part of the door and frame assembly. It is not an electronic access control system.
On retrofit projects, we assess the existing frame condition, slab clearances, and floor closer pockets before specifying the operator. In many cases we can integrate an automatic operator into a Kawneer or YKK AP frame without replacing the entire storefront opening, which keeps the project scope tighter and reduces disruption to tenants.
Every ADA entry we install includes proper threshold transitions, door swing clearances, and maneuvering clearances per ICC A117.1 and NYC Building Code Chapter 11 requirements.
What commercial door hardware does Liberty Door Supply install on Brooklyn projects?
Hardware is where a commercial entry either holds up under daily use or starts failing within a year. Brooklyn retail and commercial buildings see heavy foot traffic. The hardware has to match the load.
We specify and install:
- Panic bars and exit devices from Von Duprin (98/99 series, 33A/35A series) and Detex, sized for single and pairs of aluminum or glass doors
- Commercial door closers from LCN (1460 series, 4040XP series) and Norton, with the correct size rating for door width and frequency of use
- Push and pull hardware in stainless steel or brushed aluminum, including ADA-compliant lever handles and pull bars
- Concealed overhead stops and hold-open devices for doors in high-wind corridors or loading areas
- Threshold plates and door sweeps for weather sealing and ADA transition compliance
Hardware selection is tied to door weight, frame type, and occupancy load. A single glass door in a 10-person office gets a different closer specification than a pair of aluminum-framed doors on a 200-seat restaurant. We size everything to the actual project conditions.
If you are managing a Brooklyn property and need a storefront replacement, ADA upgrade, rolling gate installation, hardware change-out, or emergency glass repair, call Liberty Door Supply at (347) 928-7349. We serve all of Brooklyn and the wider New York City area including Manhattan, Queens, the Bronx, and Staten Island.
