Door guides for Brooklyn & NYC.

A clear scope identifies the door slab, frame, hardware, weatherstripping, fire rating, and any framing adjustments. Existing damage or structural repairs outside the door scope should be identified before work begins.

Multifamily, commercial, and mixed-use buildings in NYC often require UL-listed fire door assemblies in corridors, stairwells, and certain tenant separations. The written scope should identify the required label, self-closing hardware, and smoke-seal components.

Hardware selection depends on door weight, traffic, security goals, and ADA requirements. Locksets, closers, hinges, panic hardware, and access-control prep should be matched to the door and building use rather than treated as interchangeable.

Many binding, sagging, or latch problems stem from jamb settlement, hinge wear, or strike misalignment — not a failed slab. Structural repair can restore smooth operation and secure closure while preserving original materials when possible.

Accurate on-site measurement accounts for jamb width, header height, floor clearance, swing direction, and existing casing. Pre-war and masonry buildings often need field verification before ordering a slab or custom fabrication.

Settlement, humidity swings, masonry movement, and high-traffic use can affect how doors hang and latch. A responsible scope accounts for the building type — brownstone, loft, multifamily, or storefront — instead of assuming a standard rough opening.

The closeout plan should cover removal of old doors and debris, hardware testing, latch alignment, and a walkthrough against the written scope. Any agreed adjustments should be documented before the project is considered complete. Call (212) 505-8847 to discuss your project in Manhattan & Brooklyn.
