Most storefronts, office lobbies and condo entrances in Toronto use a closer you never see. When it fails, the door either slams, drifts open or will not close at all. Knowing which type you have tells you what kind of repair to expect.
A floor closer sits in a steel cement case under the door. The door hangs on its spindle, so the closer is controlling the swing and holding up the full weight of the leaf. That is why one worn floor closer can make a heavy glass or aluminum door drop, drag and stop latching all at once.
An overhead concealed closer (OHC) is mortised into the frame header above the door, with an arm that rides in a track or connects to the top of the door. It is the standard choice on aluminum storefront doors because it keeps the glass clean of hardware. Most OHC problems come from the arm and spindle, not the closer body.
Salt slush, mop water and melting snow collect in floor pockets and rust the cement case. Freeze-thaw cycles shift slabs and thresholds. Busy entrances open hundreds of times a day. Put those together and closer seals wear out, oil leaks and doors go out of alignment much faster than the manufacturer's spec sheet suggests.
Here is what we see most on commercial doors around the GTA, what usually causes it, what you can safely check yourself and when it is time to call a technician.
Oil on the floor around the closer cover plate, or a door that suddenly swings freely with no resistance, means the hydraulic seals inside the closer have failed. Once the fluid is gone the closer cannot control the door at all.
A door that slams is a safety problem and it is hard on the glass. Usually the sweep or latch speed valve has been turned wide open, or the closer is losing oil and cannot hold back the spring.
The door stops a few centimetres short of the frame and does not latch. In winter this lets cold air in and leaves the store unlocked overnight if staff do not notice.
The door creeps open in the wind, or the hold-open position no longer catches. On exit doors that are supposed to close and latch, this can become a fire code issue.
Scraping sounds, scratch marks on the threshold and a door that needs a shove to open. On pivot-hung doors this nearly always means the bottom pivot or floor closer spindle has worn down.
The door suddenly sits crooked, the bottom corner hits the frame or the door comes off its arm entirely. This is common on older aluminum storefronts with offset pivots.
A tapered gap along the top or latch side, a lock that only works if you lift the door, or a door that hits the header. The door has dropped on its pivots or the closer spindle is worn.
The door swings freely or flops open while the closer above seems untouched. The arm has slipped off the spindle or the track roller has come out. This is the most common OHC failure we see.
Water sitting in the cement case, rust on the cover plate, or a closer that grinds and sticks. Floor pockets near entrances collect salt water all winter.
A failed closer is rarely the only problem on a busy door. These are the services we most often combine on the same visit.

If you are replacing a closer or planning a renovation, this is how the three main types compare on Toronto commercial doors.
Handles the heaviest doors and supports double-acting swings. Fully hidden. Replacement is more involved because the door has to come off and the cement case may need work. If the floor pocket is already there, it is usually the right choice to keep.
Hidden in the header, no hole in the floor and easier to service than a floor closer. Limited by door weight and header size. Good for most retail and office entrances with medium traffic.
Visible arm, but the widest range of sizes and fire-rated options and the easiest to repair. When a concealed unit cannot be justified, a heavy-duty surface closer is the practical fix. See our commercial back door guide and fire exit door service.
Closers hold a strong spring under tension. Some checks are safe for a store manager; anything inside the closer body is not.
Every closer job is quoted after we see the door, because the brand, size and condition of the floor box change the work involved. This is how jobs usually break down.
Speed, latch and back-check adjustment, resetting an overhead arm, tightening pivots. Often done in one short visit.
New bottom pivot, top pivot, arm or spindle, plus re-hanging and aligning the door.
New floor closer or overhead concealed closer, door removed and re-hung. Rusted cement cases replaced when needed.
