A door closer is easy to ignore until it fails. Then a storefront door drifts open overnight, a back door slams on customers, or the latch never catches and the lock does nothing. In Arleta, where small businesses line Van Nuys Boulevard and the Woodman Avenue and Osborne Street strip, these doors open and close hundreds of times a day. Closers wear out, and the fix is often an adjustment rather than a replacement.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile, so there is no shop to visit. We come to your door, look at how the closer, hinges, frame and latch work together, and fix the actual cause instead of just swapping hardware.

This page covers hydraulic closers on commercial doors: what we check, how we repair or replace them, what affects the cost, and what Arleta business owners ask us most. If your door is leaving the building unsecured, call (323) 997-8867 any hour.

How it works in Arleta

  1. 1

    Tell us what the door is doing

    When you call, describe the symptom: slamming, hanging open, closing too slowly, leaking fluid, or a latch that misses the strike. Tell us if the door is glass, aluminum, hollow metal or wood, and whether it is an entry, back or stockroom door. That helps us arrive with the right equipment.

  2. 2

    Inspect the whole door assembly

    A closer often gets blamed for problems elsewhere. We check for sagging hinges, a warped or dragging door, a misaligned strike, weather stripping that binds, and a bracket that has loosened from the frame. We also look for oil leaking from the closer body, which usually means the unit is finished.

  3. 3

    Adjust sweep, latch speed and backcheck

    Many hydraulic closers have valves that control swing speed, final latching speed and, on some models, backcheck that cushions the door when it is thrown open. If the unit is sound, we tune these so the door closes smoothly and latches firmly without slamming.

  4. 4

    Repair or replace the closer

    If the closer leaks, will not hold adjustment or has a bent arm, we replace it. We match the size and mounting style to the door and traffic, and re-mount it correctly. Where the old mounting holes are stripped or the door is damaged, we reinforce it so the new closer holds.

  5. 5

    Test the latch and lock together

    We cycle the door repeatedly and confirm it closes fully from a wide-open position, latches every time and locks properly. We also check that the door meets accessibility needs for easy opening, and walk you through the adjustments so you know what was done.

What affects the price

  • Whether the closer only needs adjustment or has to be replaced, since replacement adds hardware to the job.
  • The door type and weight, because heavy steel or large glass doors need heavier-duty closers than a light interior door.
  • The mounting style and condition of the frame or door, including stripped holes, cracked aluminum or a door that needs reinforcement.
  • Whether other problems are causing the failure, such as worn hinges, a misaligned strike or a dragging door.
  • The number of doors being serviced on one visit, which can make a multi-door property more efficient.
  • The time of the call, since after-hours and emergency visits are handled differently than scheduled daytime work.

Why Arleta chooses us

  • Fully mobile service: we come to your Arleta business, so you are not hauling a door or hardware anywhere.
  • Operating since 1987, with owner David Shar leading the work, so you get experience rather than guesswork.
  • We diagnose the whole door, not just the closer, so you are not paying to replace a unit that only needed adjusting.
  • Available 24/7, which matters when a door will not latch and the building has to be secured tonight.
  • We explain what failed and what we changed, and we tell you when adjustment is enough.
  • We handle the lock side too, so a closer repair can be paired with a rekey, strike repair or deadbolt service in one visit.

Door Closer Repair across Arleta

Arleta's commercial life runs along a few arterials. Van Nuys Boulevard has a steady mix of storefronts, auto services, restaurants and small offices, and the Woodman Avenue and Osborne Street strip has its own cluster of shops and service businesses. Those doors take daily abuse from deliveries, carts and customers, and many have older closers that have been adjusted too many times or never at all.

For businesses in ZIP code 91331, we regularly see back doors propped open with a wedge because the closer no longer works, and storefront doors that swing freely because a bracket has worked loose. Near Branford Street and Branford Recreation Center and Park, and around the area served by Arleta High School, foot traffic and weather affect doors that open onto sidewalks and parking lots. A properly set closer keeps the door from slamming on a customer and from sitting ajar overnight.

Because we are mobile, we can reach the Branford Park district, the Van Nuys Boulevard corridor and the Woodman and Osborne intersection without you leaving the shop. Call (323) 997-8867 and tell us which door is giving you trouble.

Door Closer Repair in Arleta — FAQs

How do I know if my door closer needs repair or replacement in Arleta?
If the door closes too fast, too slowly or not fully, adjustment may solve it. If you see oil leaking from the body, the arm is bent, or it will not hold an adjustment, it usually needs replacing. Call (323) 997-8867 and we can help sort it out.
Can you fix a door closer after hours?
Yes. We are available 24/7 and fully mobile. If a business door will not latch and you cannot secure the building, call (323) 997-8867 and we will come to you.
Why does my door slam shut?
Usually the closing or latching speed valve is set too fast, or the closer is too strong for the door. Sometimes the cause is a binding hinge or a draft pulling the door. We check these and adjust or replace as needed.
Why won't my door latch even though the closer works?
The latch speed may be too slow, the strike may be misaligned, or the door may have sagged on worn hinges. We check the whole assembly so the latch catches reliably every time.
Do you service glass and aluminum storefront doors?
Yes, we work on closers for many commercial door types, including aluminum storefront doors, hollow metal doors and wood doors. Tell us the door type when you call so we can bring suitable hardware.
Can you repair several doors at my property in one visit?
Yes. Many commercial properties have multiple doors with aging closers. We can inspect and service them in one visit, and note any that are close to failing.
Will a closer repair affect my locks?
Often it improves them, because a door that closes and latches properly lets the lock engage as intended. We can also rekey or repair the lock hardware during the same visit.
Do you have a shop in Arleta I can visit?
No. We are fully mobile only, with no storefront. We come to your business anywhere in Arleta. Call (323) 997-8867 to get started.
