A door closer is easy to ignore until it fails. Then a storefront door hangs open overnight, a stairwell door slams hard enough to rattle a hallway, or a fire-rated door no longer latches on its own. In Glendale, where offices, apartment buildings and retail share many of the same blocks, a failing closer affects security, tenant comfort and safety all at once.
Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar has worked on a very wide range of commercial hardware in that time. We repair, adjust and replace hydraulic closers on aluminum storefront doors, office entries, apartment lobby and garage pedestrian doors, and interior stairwell and corridor doors.
We are mobile only. There is no storefront to visit, so the work happens at your door, whenever you need it. Many closers only need adjusting, so we diagnose first and replace only when the unit is truly worn out, leaking or mismatched to the door.
How it works in Glendale
- 1
Describe the problem by phone
Call (323) 997-8867 and tell us how the door behaves: slamming, closing too slowly, failing to latch, hanging open, or leaking oil. Tell us whether it is a storefront, lobby, stairwell or office door. That helps us bring the right closers and mounting hardware.

Inspect the door and closer
We check the closer body for oil leaks, the arm and bracket for looseness or bends, and the mounting screws for stripped holes. We also look at hinges, the frame and the latch, because a sagging door or a misaligned strike often gets blamed on the closer.
- 3
Adjust the valves and settings
Many hydraulic closers have separate sweep, latch and sometimes backcheck valves. If the unit is still sound, we tune these so the door closes smoothly and latches firmly without slamming. We also confirm the spring power suits the door width and traffic.

Repair or replace the closer
If the closer is leaking, cracked or no longer holds adjustment, replacement is the honest answer. We match the mounting style (regular arm, parallel arm or top jamb) to the door and frame, and we repair stripped mounting points where we can.
- 5
Test the door and the lock together
After the work, we cycle the door many times and check that the latch or deadbolt engages. We also check for ADA-minded opening effort and any accessibility concerns. We point out anything else, such as worn hinges, that could shorten the new closer's life.

What affects the price
- Whether the closer only needs adjustment or a full replacement, since repair is generally less involved than a new unit.
- The grade and brand of closer, from light-duty units to heavy-duty commercial models built for high-traffic doors.
- Door size, weight and exposure, because wide, heavy or wind-exposed exterior doors need stronger closers.
- Mounting condition, including stripped holes in aluminum storefront frames, bent arms or damaged brackets that need extra repair.
- The number of doors in the job, as a multi-door building visit differs from a single emergency call.
- Whether the visit is after hours, on a weekend or on short notice, given that we are available 24/7.
Why Glendale chooses us
- Fully mobile service, so we work directly at your door with no shop visit required.
- Operating since 1987, with David Shar as owner and lead technician.
- We adjust first and replace only when needed, rather than pushing a new closer by default.
- We look at the whole door system, including hinges, latch and strike, so the problem is actually solved.
- Our closer work pairs naturally with locks, rekeying and access hardware, so one visit can handle both the door and the lock.
- Available 24/7, which matters when a door will not secure at night.
Door Closer Repair across Glendale
Glendale has a mix of commercial doors that all put closers through hard use. Downtown along Brand Boulevard and around The Americana at Brand and the Glendale Galleria, aluminum storefront and office doors open and close constantly, and their closers wear out from sheer cycle count. Brand Boulevard high-rise condo and office buildings often combine closers with fob or access-control entries, where a door that does not fully close can defeat the electronic lock entirely.
Further from the core, apartment buildings from the 1960s through the 1980s are common across 91201, 91202, 91205 and the neighborhoods around Central Avenue and Glenoaks Boulevard. Lobby, stairwell and garage pedestrian doors in these buildings run all day, and tenants notice quickly when one slams or hangs open. Property managers in those buildings often call us for closers alongside rekeying or lock work.
Older neighborhoods such as Rossmoyne and Adams Hill, and the hillside streets of Verdugo Woodlands near the Verdugo Mountains, are mostly residential, but small offices, medical suites and multi-unit properties there also rely on working closers. Whether you are near the Alex Theatre, off Colorado Street, or just off the SR-134, SR-2 or I-5, we come to you.
