Door Closer Service San Antonio

A door closer is the hydraulic arm at the top of a commercial door that controls how it swings shut. We repair, adjust, and replace failed or leaking closers in San Antonio — tuning the sweep, latch, and backcheck speeds, setting ADA-compliant opening force, and sizing the right closer to your door's width and weight. Express Local Service is a licensed Texas locksmith (B19775), and we give you the exact price before any work.

Most closer calls come down to adjustment or replacement. We fine-tune the three valves that control the door — sweep speed (the main swing), latch speed (the final inches that seat the door), and backcheck (the cushion that stops the door slamming into a wall) — so the door closes fully without banging or dragging on the strike. When a closer leaks hydraulic fluid, has lost its tension, or won't hold a setting, the seals are gone and it needs replacement. We size the new unit to your door's width and weight (closers are rated by size), match the arm type — regular, parallel, or hold-open — and set ADA opening force so the door isn't too heavy to pull. We also service fire-door closers, where the self-closing function is code-required and must latch every time. Pairing it with a commercial hardware review, or sorting out a business lockout on the same door, is easy to handle in one visit.
