Door Closer Repair & Adjustment in Tampa
A closer that slams the door, leaks oil, or leaves the door an inch short of latching is more than an annoyance: a door that doesn't latch isn't locked. We adjust and replace commercial door closers on Tampa storefronts, office entrances, back doors, and the common doors of multi-tenant buildings.
What Your Door Is Telling You
Most people don't think about a closer until the door starts slamming or stops latching. Here's what each symptom usually points to:
Slams Shut
Every slam hammers the latch and strike, shakes the glass, and makes customers jump. Often it's an adjustment; sometimes the closer is failing.
Stops Short of Latching
The door drifts to the frame and stops just short. It looks closed but isn't locked, which matters most on entrances, exits, and doors with keypads or readers.
Leaking Oil
Oil on the closer, the door, or the floor means it's losing the hydraulic fluid that controls the door. A leaking closer gets replaced, not readjusted.
Caught by the Wind
An exterior door thrown open by a gust and slammed into the wall needs back-check set, or a closer sized for the door and the wind it sees.
Hard to Push Open
If people have to lean on the door, the closer may be too strong for it, or the door may be binding in the frame. We check both.
Arm Loose or Bent
A loose arm, stripped screws, or a bent arm lets the door wander. Sometimes that's a remount; sometimes the arm or the closer needs replacing.
Sweep, Latch, and Back-Check: The Three Adjustments
Most commercial door closers are hydraulic: a spring closes the door, and oil moving through small adjustable valves controls how it moves. Three settings do most of the work:
- Sweep speed sets how the door moves through most of its swing, from wide open to near the frame.
- Latch speed sets the last stretch before the door closes, where it needs enough push to snap the latch into the strike.
- Back-check cushions the door near full open, so a hard push or a gust doesn't slam it into the wall.
Plenty of slamming and drifting doors come down to those settings. We adjust in small steps and test the door after each change, because the right setting depends on the door, its weight, and where it is.
Closing Speed and Opening Force: What the Rules Say
On doors that are part of an accessible route, the 2010 ADA Standards set a minimum closing time: door closers “shall be adjusted so that from an open position of 90 degrees, the time required to move the door to a position of 12 degrees from the latch is 5 seconds minimum” (2010 ADA Standards, 404.2.8.1). The timing stops 12 degrees from the latch, leaving the last stretch to the latch speed setting, so a door can close slowly enough for someone using a wheelchair or a walker and still latch firmly.
The same standards limit the opening force of interior hinged doors to “5 pounds (22.2 N) maximum,” leave fire doors at “a minimum opening force allowable by the appropriate administrative authority,” and don't count the force needed to retract a latch (404.2.9). They set no maximum for exterior hinged doors, but Florida does: “exterior hinged doors must be designed so that such doors can be pushed or pulled open with a force not exceeding 8.5 foot pounds” (Fla. Stat. 553.504(3)). Florida adopts the federal standards into its Florida Accessibility Code for Building Construction (Fla. Stat. 553.503).
In practice it's a balance: enough force to close and latch an exterior door against Tampa's wind and the building's air pressure, and no more. For exterior doors, the U.S. Access Board's guide says closers “should be calibrated with the least force necessary for closure to minimize the opening force” (U.S. Access Board), and that's how we set them. Your building official has the final word on what applies to a given door.
Commercial Door Closer Replacement, Sized to the Door
Some closers are done: leaking oil, a cracked body, or a closer that won't hold an adjustment. We replace them with closers sized for the door's width and weight, its location, and the wind it sees. An undersized closer can't control a heavy exterior door, and an oversized one makes the door hard to open.
A closer works as a system with the hinges or pivots, the latch and strike, and the lock or exit device. If the door sags or rubs the frame, a new closer won't fix it, so we check the door first and correct its alignment where needed. On fire-rated doors, we keep the hardware rated, closer included. That goes for entrances, back doors, warehouse personnel doors, and multi-tenant common doors across Hillsborough and Pinellas.
A Door That Doesn't Latch Isn't Locked
A closer is a security part, not just a comfort part. Locks, exit devices, and access control readers all assume the door closes and latches. If the closer leaves the door an inch short, the lock can be locked and the door still open.
That's why closer trouble often shows up as a “lock problem,” and why we check the closer, latch, and strike before we install a keypad or reader (see commercial access control). If the latch or exit hardware is the real problem, see panic bar repair or storefront door locks. For the keys, see master key systems, and for codes instead of keys, keyless entry for homes and businesses.

Call (813) 832-4777Door Closer Questions
Can a slamming door be fixed with an adjustment?+
Often, yes. Most hydraulic closers have separate valves for sweep speed, latch speed, and back-check, and a slamming door usually means one of them is set wrong. If the closer leaks oil or won't hold a setting, it should be replaced instead.
Why is my door closer leaking oil?+
Its seals have failed, and it's losing the hydraulic fluid that controls the door. Readjusting won't hold, so a leaking closer gets replaced with one matched to the door's size and weight. Wipe up the oil in the meantime; it's a slip hazard.
Why won't our door latch when it closes?+
Usually the latch speed is set too slow, the closer is too weak for the door, or the door is dragging or out of line with the strike. Wind and the building's air pressure can also hold a door open the last inch.
How slowly should a commercial door close?+
On doors that are part of an accessible route, the 2010 ADA Standards require that a closer take at least 5 seconds to move the door from 90 degrees open to 12 degrees from the latch (section 404.2.8.1). We set the sweep with that in mind, then set the latch speed so the door still latches.
How hard should a door be to open?+
The 2010 ADA Standards limit interior hinged doors to 5 pounds of opening force, not counting the force needed to retract the latch, and leave fire doors to the appropriate authority (section 404.2.9). For exterior hinged doors, Florida law sets a limit of 8.5 foot pounds (Fla. Stat. 553.504(3)). Your building official has the final word on a given door.
Do you replace closers on storefront doors?+
Yes, including closers on aluminum-and-glass storefront entrances, sized to the door and the wind it sees. Bring a photo of the closer and the top of the door, or describe them when you call.
How much does door closer repair cost?+
It comes down to whether the closer can be adjusted or has to be replaced, and to the door's size, weight and location, which decide the closer it needs. We don't post prices; quotes are free, and yours comes before any work starts.
