Commercial door closer repair and replacement in NYC

Four kinds of commercial closer

• Surface closers: mounted on the door or frame with a visible arm. The usual closer on stairwell, corridor, apartment and service doors. We install and service LCN surface closers such as the 4040XP and 4010 Series; see commercial door hardware.
• Overhead concealed closers (OHC): the closer body sits hidden in the header of an aluminum storefront or glass door, with an arm and track in the top rail. See overhead concealed closers.
• Floor closers: set in a cement case under the floor at the pivot point of a center-hung or offset-hung door. Standard on frameless glass and Herculite doors. See floor closer repair and replacement.
• Automatic operators: low-energy and power operators with push buttons or touchless actuators for ADA entrances, such as the LCN 4630 Auto Equalizer and 9140 Benchmark. See automatic door operators and ADA doors.

Signs a closer needs service

• The door slams, or creeps closed and never latches
• The door swings past the stop or will not stay centered in the frame
• Oil on the floor plate, the header or the door
• The arm is loose, bent or disconnected from the track
• The door is too heavy to open for ADA, or blows open in the wind
• A fire or stairwell door no longer closes and latches by itself

Who we work for

• Storefronts and retail chains: entrance doors that have to open all day and still close and lock at night
• Building lobbies: glass and aluminum entrances that take heavy traffic, wind and weather
• Office suites: glass suite doors and interior Herculite-style doors with concealed closers
• Property managers and multi-location businesses: one vendor, one invoice format, and the same hardware spec across sites

Brands we install, replace and service

We install, replace and service floor closers, overhead concealed closers and glass-door hardware from Rixson, dormakaba (DORMA), FHC (Frameless Hardware Company) and CRL (C.R.

How a closer job runs

• Call or send photos of the door, the closer and any model plate or cover plate
• Diagnosis on site: adjust what can be adjusted, and identify the closer, spindle, arm and pivots when it has to be replaced
• Written estimate with the part, the labor and whether the part is in stock or has to be ordered
• Install and set: sweep, latch speed, backcheck and opening force, then a test with the lock and any access control
