Every commercial building in Ottawa relies on door closers for daily use, security, and safety. When these small devices start failing, it causes more than just inconvenience. Doors may slam shut, remain open, or create safety hazards. Over time, wear adds up. As a locksmith in Ottawa, we regularly troubleshoot these issues in high-traffic locations. To keep your property working smoothly, it helps to understand why door closers fail and what signs to look for.
Incorrect Installation From the Start
Many problems begin the moment a door closer gets mounted. If the wrong model is installed or the arms are not positioned precisely, the unit works against itself. Misalignment makes the arm strain, which leads to early failure. We often find screws pulled from the door, arms bent, or misadjusted swing settings.
Improper torque during installation can cause leaks or stress the valve. Sometimes, the installer skips critical adjustments like backcheck or latch speed. These missed steps make the door slam, drag, or never close fully. In commercial buildings, these details matter daily. Doors get constant use, and even slight misalignments grow into bigger problems over time.
We’ve fixed countless units where the only issue was incorrect placement or skipped calibration. This is why we always check fit and tension when providing commercial locksmith Ottawa services. That way, future wear is minimized.
Internal Fluid Leaks and Seal Failure
Some closers work using sealed hydraulic chambers. These chambers contain a special fluid that controls the door’s speed and resistance. When seals fail or the internal fluid starts leaking, the door moves too quickly or too slowly. This happens silently at first, but over time, it causes a slamming door or one that refuses to stay closed.
Leaks can start with tiny cracks or temperature-related expansion. Cold Ottawa winters make seals brittle. Then, when buildings heat up during the day, the material expands, which stresses the housing. If you see oil near the hinge or on the floor, the closer is already compromised.
There’s no fix once a unit begins to leak fluid. The entire closer needs to be replaced. We usually catch this during maintenance or when staff notices a sudden shift in closing speed. Sometimes, the leak happens internally, and the first sign is erratic motion. For this reason, we recommend inspections every six months in busy buildings.
Lack of Regular Maintenance
It might seem like door closers are set-and-forget hardware, but they’re not. Moving parts need regular inspection. Screws back out, arms loosen, and pivots wear. If no one checks them, the door gets harder to use. Over time, force increases at the hinge, which may cause the closer to snap or jam entirely.
Grease dries up and makes motion stiff. As a result, people push harder on the door. This wears out the gears or throws off internal timing. Preventing these issues is easier than most think. Simple checks twice a year help catch tension imbalances or signs of wear. For example, if a closer pulls unevenly or no longer holds the latch gently, adjustment is needed.
Building managers often overlook these devices until a tenant complains. By then, damage has usually set in. That’s why we include closer inspections in most of our service calls. Our work as a locksmith in Ottawa often uncovers small closer faults before they turn into full replacements.
Exposure to Weather and Corrosion
Some commercial doors sit at building exteriors where wind, rain, and snow are common. Even when the closer is covered, moisture finds its way inside. Over time, water corrodes internal springs, rusts moving arms, and weakens the unit. Winter salt tracked from boots can also accelerate wear around the floor pivot and anchor points.
Even slight corrosion in the adjustment valve can block fluid flow. That causes unpredictable closing speeds or loud creaks. When this happens near a public entrance, it affects both accessibility and safety. It can also void fire exit compliance if the door doesn’t shut properly.
Our team always inspects for signs of rust or wear, especially on street-facing units. When buildings don’t use weather-rated closers, problems appear faster. If you’re dealing with salt exposure or door alignment issues from freeze-thaw cycles, it may be time to install new hardware or upgrade the sealing.

Vandalism and Forced Damage
High-traffic buildings in Ottawa often see rough use of their entry doors. In some cases, it’s not accidental. People push hard, hang on handles, or try to stop the door mid-swing. These behaviors stress the closer arm and linkage points. If someone kicks the door open or yanks on the arm, even a sturdy closer can break internally.
Misuse usually bends or cracks the main shaft or tears the closer away from the mount. In retail and school environments, these impacts are common. They create alignment issues or completely snap return springs. If doors get stuck open or jam mid-swing, this kind of damage is likely the reason.
We often get calls after a security camera review shows someone forcing the door. In those cases, fast repair prevents further issues. Building managers who regularly deal with vandalism should consider tamper-resistant closers and mounting plates. These upgrades reduce future breakage and make the door safer for all users.
Obstructions Blocking the Door’s Path
It’s easy to forget how much impact a doorstop, wedge, or mat can have on a door closer. Even temporary obstructions, like a box or misplaced bin, can change the way the door swings. Over time, the internal pressure builds because the closer fights to complete its motion.
Every time the door hits an obstacle, the arm absorbs shock. This impact loosens the mount or damages the linkage. Some closers have internal pressure limiters, but most do not. If the door constantly gets propped open, the closer loses its resistance balance. Eventually, the arm slips or bends out of shape.
Staff should be trained to avoid holding doors open with random objects. It’s safer to use hold-open arms designed for that purpose. We also advise facility teams to double-check door paths for clutter. When the issue comes from poor habits, prevention makes a bigger difference than constant repair.
Overuse Without Durability Rating
Not all door closers are built for heavy traffic. Some models are made for occasional use, like in storage rooms or private offices. When those units are used on main entrances, they wear out much faster. The parts inside aren’t meant for constant cycles, and spring fatigue develops quickly.
In busy commercial settings like clinics, schools, or retail, a low-grade closer won’t last long. We’ve replaced units that failed within a year simply because the rating didn’t match the real usage. In these cases, the closer may not hold the latch or allow slamming even after multiple adjustments.
When we inspect failing units, we always check the cycle rating. A higher-grade closer might cost more at first, but it performs better for longer. If your entry sees hundreds of uses daily, upgrading now avoids repeated breakdowns. The right closer matches traffic load, weight, and door material.
FAQs
How do I know if my door closer is failing?
Watch for signs like slamming, doors staying open, or difficulty closing fully. Fluid leaks or loud noises also signal internal issues.
Can I adjust a door closer myself?
Some models allow basic adjustments. However, incorrect changes can cause damage. It’s safer to have a trained technician handle it.
Why is my commercial door slamming shut?
The internal fluid may have leaked, or tension settings could be wrong. In some cases, the arm is bent from misuse.
Is a leaking door closer dangerous?
Yes. Fluid leaks affect performance and can create slip hazards on floors. Once a unit leaks, it usually needs replacement.
Should I replace a door closer or repair it?
If the issue is minor, like a loose arm, repairs may work. But if there’s internal damage or fluid loss, full replacement is better.
