Door closers in Markham — office campuses, clinics and accessible entrances
A lot of Markham closer work is on doors that also have to be accessible. Clinics, schools and office campuses run entrances with push-button operators, and the closer and the operator have to be set to work together. When they are not, the operator fights the closer, the door judders, and the operator burns out well before its time.
The rest is ordinary commercial wear on plaza and restaurant entrances, plus the fire exits at the back of every one of those units. Markham buildings tend to be inspected properly, so the closers on fire-rated openings get found when they stop pulling the door fully home.
Door closers we service in Markham

Surface-mounted closers adjusted, rebuilt or replaced with hardware sized for the door and its traffic.

In-frame and floor-spring closers on aluminum and glass entrances, serviced or replaced.
Arms & brackets
Bent arms, stripped brackets and pulled mounting plates repaired with proper backing.

Fire-rated openings
Closers on fire doors set so the door closes fully and latches positively, as an inspector requires.
The closer faults we are called out for in Markham
The door slams
The latch speed valve has drifted, or the closer is undersized for the door. On an aluminum entrance it is often a worn bottom pivot underneath a perfectly good closer, which is why we check both.
The door does not close the last few inches
Lost latching power. The door rests against the frame instead of latching, so the unit is not actually secure and, on a fire door, provides no fire separation.
The accessible operator is fighting the closer
A push-button operator has to overcome the closer spring. If the closer is set too strong the operator strains, the door judders and the unit fails early. We balance the two so they work together.
The closer is leaking oil
A blown seal. Once a closer starts weeping it will keep losing control until it fails, and it cannot be refilled. This one is a replacement.
The arm is bent or the bracket has pulled out
Usually a door flung open in the wind with no back-check set. We repair the backing so the new hardware has something solid to mount to, then set back-check so it does not happen again.
The door stands open on its own
A hold-open arm engaged, or a closer that has lost its spring. On a fire-rated opening a door that stays open is a deficiency, not a convenience.

Door slamming, standing open or not latching?
A door that will not latch means the unit cannot be secured. Those get priority dispatch, 24 hours a day, seven days a week.
Commercial closers in Markham
A closer is the part that decides whether a commercial door actually latches, which makes it a security component and, on a fire-rated opening, a compliance one. A door that swings shut but rests against the frame is not latched, gives no fire separation and can be pulled open.
Related work includes commercial door closer replacement, pivot hinge replacement, aluminum and glass doors, fire exit doors, commercial door repair and scheduled commercial door maintenance.
Set the latch speed, not just the sweep
Most closers have two speed valves: sweep, which controls the long swing, and latch, which controls the last few inches. Almost every complaint about a door that slams or fails to latch is the latch valve, not the sweep. Setting them independently is what makes a door close quietly and still latch every time.

Door closer repair Markham — frequently asked questions
How fast can you get to Markham?
Most Markham calls are same-day and we work after hours so a busy entrance can be fixed outside trading. Call 647-951-3510.
My door slams. Can the closer just be adjusted?
Sometimes. But on an aluminum entrance a slamming door is usually a worn bottom pivot underneath a closer that is set correctly — we check both before charging for either.
The closer has pulled off the door. Is that fixable?
Yes. The mounting has torn out of the door or frame. We repair the backing so the new closer has something solid to hold on to.
What is back-check and why does it matter?
It is the resistance near the fully open position that stops the door being flung into the wall. On a windy entrance it is the setting that saves the closer and the frame.
Do you charge to quote?
No. Assessments are free and the price is confirmed in writing before any work starts.
Can you set a door to hold open for deliveries?
Yes, with a hold-open arm or a delayed-action closer — as long as it is not a fire-rated opening, which must self-close.
Is the work warrantied?
Yes, on labour and on the hardware we supply, written on your invoice.
Can you invoice the business?
Yes. We also take cash, debit, e-transfer and all major credit cards.

Why you need an expert for installations and repairs
Most door closers have two or more valve adjustments. One valve adjustment operates to regulate the closing speed of the door. The other valve adjustment facilitates the latching speed of the door. The speed of the door closer is in general, between 100 and 20 degrees, whereas the latching speed operates between 20 and 0 degrees. What confuses in experience handymen is that, in addition to these valve adjustments, door closers have other similar adjustments which can be mistaken for valve adjustments. Any mistakes here can significantly damage your door.
