Commercial Door Maintenance Guide

Commercial doors live a harder life than anything in a home. An entrance to a busy office, clinic, or shop can cycle several hundred times a day, every day, through Ottawa's full range of weather. That volume turns small, ignorable issues into failures fast — and a failed entrance is not just an inconvenience, it is lost foot traffic, a security gap, and sometimes a code violation. A simple, consistent maintenance routine prevents the great majority of those failures.

Build a simple inspection schedule

The single most valuable habit is looking at your doors on a schedule instead of waiting for one to break. For most properties:

• Monthly — a quick walk-by check of each main entrance: does it close and latch on its own, are there new noises, is anything dragging or sticking?
• Quarterly — a hands-on check of hardware: closers, hinges, latches, seals, and thresholds.
• Twice a year — a full service, ideally in fall before winter and spring after it, when seasonal movement and salt damage show up.

What to check, component by component

Door closers. The closer is the hardest-working and most failure-prone piece of hardware on a commercial door. Watch how the door shuts: it should swing closed smoothly and latch without slamming or stalling. A door that slams is hard on the frame and latch; a door that does not fully close is a security and energy problem. Oil weeping from the closer body means the seals are failing and it needs service or replacement.

Hinges and pivots. Heavy commercial doors put enormous load on their hinges. Check for sagging, squeaking, and loose or backing-out screws. A door that has dropped even slightly will drag on the threshold and stop latching cleanly, which then strains the closer. Tighten, lubricate, and replace worn hinges before the sag spreads.

Exit and panic hardware. On doors equipped with panic bars or exit devices, the priority is life safety: the device must release reliably with a single motion every time, with nothing obstructing it. Test it regularly and never allow it to be chained, blocked, or disabled — that is both dangerous and a serious code violation.

Weatherseals and thresholds. Commercial entrances bleed conditioned air through worn perimeter seals and sweeps, and Ottawa's road salt and grit chew up thresholds. Replace flattened seals and worn sweeps to control heating and cooling costs, and keep thresholds clean, secure, and draining properly.

Locks and latches. Confirm that latches engage fully and that locks operate smoothly. A latch that only catches sometimes is a door that is not secure. Lubricate cylinders with a dry lubricant and address any lock that has to be coaxed.

Automatic operators and sliding entrances

Automatic doors add sensors, motors, and safety beams to the maintenance list. Test that the door opens and closes at the right speed, that the safety sensors stop it when something is in the path, and that it does not slam or stall. Keep tracks and sensor lenses clean — grit and salt buildup is the most common cause of erratic operation. Because these systems have a direct safety function, anything that behaves unpredictably should be serviced promptly rather than left running.

Fire-rated doors: a special responsibility

If your building has fire-rated doors, they are part of its fire-protection system and carry legal obligations. A fire door only works if it self-closes and positively latches on its own, every time, with its seals, hardware, and rating label intact and unmodified. They should never be propped open with anything but an approved hold-open device tied to the alarm, and any fire door that fails to close and latch must be corrected without delay.

Why maintenance beats repair

Every item above shares a theme: a small, cheap fix done on schedule prevents a large, expensive failure later. A worn closer caught early is an adjustment; ignored, it slams the door until the frame cracks and the hinges fail. Planned maintenance also means you choose when a door is out of service — after hours, on your terms — instead of scrambling when an entrance fails during business hours. For most Ottawa businesses, the cost of a maintenance routine is a fraction of the cost of the downtime, emergency calls, and collateral damage it prevents.
