Door Repair & Installation in NYC
NYC Glass & Window Repair provides professional door repair and installation for commercial buildings, storefronts, offices, restaurants, retail properties, apartment buildings, condos, co-ops and residences.
A door that drags, slams, will not latch or will not lock does not automatically need replacement. Many failures originate in the closer, pivots, hinges, lock, exit device, threshold, weatherstripping or alignment. We diagnose the system first and determine whether targeted repair can safely restore reliable operation.

Commercial & Storefront Door Repair
Commercial Door Repair NYC
Commercial entrances see constant traffic. We diagnose doors that are sagging, scraping, slamming, closing too slowly, failing to latch or lock, or rubbing the threshold or frame, and correct the underlying alignment or hardware issue rather than repeatedly adjusting a symptom.
Storefront Door Repair
Aluminum storefront doors combine a narrow frame with glass, pivots or hinges, closers, locks, thresholds and weather seals. We repair closers, pivots, continuous hinges, locks, cylinders, handles, thresholds, weatherstripping and glass. For complete storefront framing and glazing systems, see Storefront Installation & Repair.
Glass Door & Herculite Door Repair
Frameless and Herculite doors need hardware designed for heavy tempered glass. Common problems include sagging, dragging, failed floor closers, worn pivots, loose patch fittings and doors that no longer return to the closed position. We evaluate the glass, patch fittings, rails, pivots, closers, handles and locks as one system. Replacement glass must be fabricated with correct dimensions, thickness, holes and notches, since tempered glass cannot be cut afterward.
Closers, Pivots, Locks & Exit Devices
Door Closer Repair & Replacement
A properly adjusted closer controls the door through its swing and brings it securely closed without slamming. We service surface-mounted, overhead concealed and floor closers. A leaking or mechanically failed hydraulic closer generally requires replacement rather than repeated adjustment.
Floor Closers, Pivots & Concealed Hardware
Wear in concealed hardware can make a door drop, drag or miss the lock and frame. Diagnosis may require exposing or measuring existing components, and replacement must account for door weight, dimensions, handing and traffic.
Panic Bar & Exit Device Repair
We repair and replace exit devices, strikes, trims and cylinders. Where a door is part of a required means of egress or a fire-rated assembly, hardware must be compatible with that assembly and existing labels must not be compromised.
Locks, Hinges & Alignment
A door that will not lock is not always a defective lock: sagging hinges, worn pivots, frame movement or a misaligned strike can be the cause. We inspect the door, frame, latch and strike together, and evaluate butt hinges, pivots and continuous hinges for wear and attachment failure.
Door Glass Replacement & New Door Installation
Broken door glass can often be replaced while the frame and hardware remain serviceable. Door locations usually require safety glazing, so the replacement must be appropriate for the application. For glass-only projects see Glass Replacement & Installation.
When a door or frame is severely damaged, corroded, deformed or unsuitable for its use, replacement may be the better long-term solution. Professional installation includes frame preparation, anchoring, clearances, hardware locations, closer setup, locking alignment, thresholds, perimeter sealing and final adjustment.
Repair or Replace the Door?
Repair is often appropriate when
A closer has failed; hinges or pivots are worn; the door is misaligned; a lock or exit device can be replaced; glass is damaged but the frame is serviceable; weatherstripping or thresholds are worn.
Replacement may be appropriate when
The door or frame is structurally damaged; corrosion is extensive; repeated repairs no longer restore reliable operation; or the system cannot meet current operational needs.
Our goal is to recommend the scope that addresses the actual failure, not to replace a complete system when a durable repair is practical.
Residential, Sliding, Terrace & Balcony Doors
We repair and install entry doors, interior glass doors, terrace and balcony doors, patio and sliding doors, locks, hinges, weatherstripping and alignment problems in apartments, condos, co-ops, townhouses and private residences.
Sliding and terrace doors become difficult to operate from worn rollers, damaged tracks, failed locks, deteriorated weather seals and misalignment. Swinging balcony doors may develop hinge, handle, multipoint-locking or compression-seal issues. In managed buildings, work may require a certificate of insurance, approved hours and superintendent coordination.
Emergency, Fire-Rated & Access-Controlled Doors
Emergency Door Repair NYC
Emergency service may include removal of hazardous glass, temporary board-up, securing the opening, urgent hardware work and measurement for permanent components. Custom tempered glass, doors and specialty hardware may require fabrication before permanent completion.
Fire-Rated Doors
Fire-rated doors are tested assemblies of compatible doors, frames, glazing and hardware. Repairs must preserve the listed assembly and labels; a part that physically fits is not automatically compliant. We verify the existing assembly before finalizing scope.
Automatic & Access-Controlled Doors
Door geometry and mechanical operation must be correct before electric strikes, magnetic locks or card access can work reliably. Specialized electrical, low-voltage or automatic-door certification work is coordinated with the appropriately qualified trade.
Hardware Brands, Commercial Clients & High-Rise Work
We work with commercial and architectural hardware commonly found in NYC, including systems associated with Adams Rite, CRL, Dormakaba, LCN, Norton, Yale, Falcon and Von Duprin. Model, handing, dimensions, preparation and door weight all matter, so exact identification reduces repeat failures.
We serve property managers, building owners, general contractors, retailers, restaurants, offices, schools, hotels, healthcare facilities, condos and co-ops. Commercial work may need COIs, elevator scheduling, after-hours work or staged repairs, and multi-door surveys can document recurring problems and prioritize repairs. High-rise terrace doors face heavy weather exposure, and landmark entrances may require preservation of profiles and hardware appearance.

Frequently Asked Questions
Often, yes. Closers, pivots, hinges, locks, exit devices, glass, thresholds and other components can frequently be replaced while retaining a serviceable door and frame.
Common causes include worn pivots or hinges, loose hardware, door or frame movement, threshold interference and alignment problems. The cause should be diagnosed before adjustment.
Yes. A failed or incorrectly adjusted closer is a common cause, but door alignment and hardware should also be checked.
Yes. We evaluate frameless glass doors, patch fittings, floor closers, pivots, rails, locks and handles, subject to component condition and availability.
Yes, for compatible commercial door systems. Required egress or rated assemblies must use appropriate components and should not be modified in a way that compromises the assembly.
Yes. When the frame is serviceable, the glass can often be replaced without replacing the complete door. Door locations commonly require safety glazing.
Yes. New installation and replacement scopes are evaluated based on the opening, door type, hardware, security, accessibility, weather exposure and building requirements.
Urgent service is available for appropriate conditions such as unsecured doors, broken glass and critical hardware failures. Availability and permanent completion depend on location, parts and fabrication requirements.
