Door Closer Installation

Door closer installation and repair starts from $150. Locksmith Auto installs, adjusts, and replaces commercial door closers for fire code and ADA compliance. Surface-mounted, concealed, and floor-spring models. All major brands.

Three main types of commercial door closers. Surface-mounted closers bolt onto the door face or frame — the most common type, found on every office, store, and restaurant door. Concealed closers hide inside the door or frame for a clean appearance, popular in upscale offices and hotels. Floor-spring closers mount under the floor and work with glass or aluminum storefront doors.

Fire code requires a door closer on every fire-rated door in a commercial building. ADA mandates controlled closing speed with no more than 5 pounds of force to open. When your closer fails, you are out of compliance on both counts. Fire marshal inspections catch doors that do not close fully, and that can mean fines or a failed inspection.

Common problems we fix. Doors slamming shut — the hydraulic valve needs adjustment or the closer is oversized for the door. Doors that do not close all the way — the arm or spring tension is wrong. Leaking hydraulic fluid — the closer body is cracked and needs full replacement. Slow or uneven closing — internal valves are clogged or worn.

Locksmith Auto installs closers from LCN, Norton, Dorma, and Sargent. Surface-mounted units start at $150. Concealed closers run $250-450. Floor-spring closers cost $350-600. We size the closer to match your door weight, width, and daily traffic volume. Every installation includes adjusting closing speed, latching speed, and backcheck. 90-day warranty on parts and labor.
