The door will not shut on its own any more. Or it shuts, but it slams hard enough to rattle the frame, or it drifts to within an inch of the latch and stops there, so the door looks closed and is not. Somewhere above the hinge side there is an arm and a metal body with oil in it, and that is the part that has stopped doing its job.
This page is about what that costs to put right in Canada, and about the one situation where the cost is not the deciding factor at all. It does not explain how to get through a locked door, and it does not explain how to take a closer off a door, because on some doors that is the thing you are specifically not allowed to do.
A door closer is two purchases, not one. The part has a public price you can look up yourself, from about $20 to $210 at Home Depot Canada depending on which class of door it is built for, read 19 September 2026. The installed job, quoted by a commercial door company, runs higher than any of those parts. Knowing the first number is what lets you ask a sensible question about the second. And if the door is a fire door, the closer is required equipment and the choice to remove it is not available to you.

What you are actually buying
On a job that combines a part with labour, the temptation is to look for one number and compare it to another. That is the wrong shape. A door closer failure is a short shopping list, and the items on it are priced in different units by different trades.
There is the closer itself, priced per unit, sold on a shelf. There is the labour to remove the old one and mount the new one, priced per visit or per door. And on a commercial door there is often a third item that nobody mentions on the phone, which is whether the replacement is rated for the door it is going on. Those are three separate purchases with three separate reasons to go wrong.
Exactly one line of that list has a price you can check before you call anyone. That is the whole of your bargaining position, and it is worth more than it sounds. It turns a quote you cannot evaluate into a quote with one known term in it.
Which failure you have
Door closers fail in a small number of recognisable ways, and they are not equally expensive.
The door slams, or closes too slowly to latch. On most closers the sweep speed and the latch speed are set by two adjustment valves on the body of the unit. A closer that has drifted out of adjustment has not failed at all. This is the cheapest outcome and the reason a technician will look at the valves before quoting anything.
There is oil on the door, the frame or the floor. A hydraulic closer that is leaking is finished. The oil is the mechanism, and closers are sealed units, so a leak is not something that gets topped up. This one goes on the replacement side of the list without much argument.
The arm is bent, or the bracket has pulled out of the frame. Here the closer may be fine and the mounting is the problem. Wood that has been pulled at for years does not always take a screw back, which is why a job that looks like hardware turns into carpentry on arrival.
The door itself has dropped, or the frame has moved. The closer gets blamed for this constantly. If the door no longer sits square in its opening, no amount of adjustment makes it latch, and replacing the closer changes nothing. Seasonal movement in an exterior frame is common enough in this climate that it is worth ruling out before buying hardware.
One more thing changes the quote before anyone touches a valve, and it is worth saying on the phone: whether the closer is mounted on the face of the door or hidden inside the door or frame. A surface-mounted unit is visible above the hinge side and comes off with a screwdriver. A concealed one is fitted into the door edge, the frame head or the floor, and reaching it is a different piece of work with a different bill attached. We found no Canadian business publishing separate prices for the two, so the only way to know which you are being quoted is to describe what you can see.

Read that ladder by the names rather than by the numbers, because the names are doing the work. A storm door closer at the bottom of the list is a light pneumatic tube for a screen or storm door. A Grade 1 commercial closer at the top is a hydraulic unit for a heavy swing door in a building people work in. They are not cheap and expensive versions of the same thing, and the ten-fold gap between them is not a saving available to you. It is the difference between two products that happen to share a category page.
What the ladder does give you is a ceiling. If the door in front of you is an ordinary commercial swing door, the part is very unlikely to be the largest line on the invoice.
The installed job: what a contractor charges
Canuck Door Systems, a Canadian commercial door company, publishes cost ranges for commercial door work. Read on 19 September 2026, that page puts replacing a hydraulic closer at $250 to $450, and says that minor hardware adjustments covering closers, hinges, seals or latches “typically stay under $400”. For a fire-rated entry assembly it lists repair at $250 to $750 and replacement at $1,200 to $3,000 and up. These are ranges published by the business and not verified by us.
| Work, as the page describes it | Published range |
|---|---|
| Minor hardware adjustments: closers, hinges, seals or latches | under $400 |
| Replacing a hydraulic closer | $250 to $450 |
| Fire-rated entry assembly, repair | $250 to $750 |
| Fire-rated entry assembly, replacement | $1,200 to $3,000 and up |

Now put the two tables beside each other, carefully, because they are not answering the same question. The first is a shelf price for a box. The second is a price for a visit that ends with a working door. The published closer replacement range does not say whether the part is included in it, and that single unstated term is the most useful thing to settle on the phone.
The same page offers a decision rule worth borrowing: if repairing the door would cost more than half of a brand new system, it treats replacement as the better long-term call. That rule is about the door assembly rather than the closer alone, but the arithmetic transfers. A $400 adjustment on a door that needs a $210 closer is worth questioning. A $400 adjustment that saves a $1,200 assembly replacement is not.
If it is a fire door, the decision is not yours
This is the section that changes the shape of the problem, and most cost pages on this subject skip it.
Fire doors are required to close and latch by themselves. Alberta’s safety codes guidance on fire doors, citing the National Building Code 2019 Alberta Edition, states that “every fire door shall be equipped with a self-closing device designed to return the door to the closed position after each use”, together with “a positive latching mechanism designed to hold the door in the closed position after each use”. The same guidance is explicit about what may not be done to one: “At no time shall the fire doors be obstructed, blocked, wedged open, or altered in any way that would prevent the intended operation of the fire door.” You can read it in the Alberta fire door guidance published at ebs.safetycodes.ab.ca, which we opened on 19 September 2026.
Building and fire codes are administered provincially and the requirements are not uniform, so treat the Alberta wording as the example we were able to open rather than as the rule where you are. We are not summarising thirteen provincial and territorial codes from memory. Our approach to checking what we publish is set out on how we check listings, and it explains why we date everything and verify less than people assume.
Two practical consequences follow. The first is that on a fire door, taking the closer off and living without it is not one of the options on your list, whatever it would save. The second is subtler and costs people money: the same guidance warns that fire doors are compromised by “the installation of non-rated hardware, incompatible hardware and repairs that do not maintain the integrity of the fire-protection rating”. A closer bought on price alone, fitted to a rated door, can turn a working assembly into a non-compliant one. That is the third line of the shopping list, the one nobody mentions, and it is the reason the cheapest quote on a rated door is sometimes the expensive one.
If you are not sure whether your door is rated, there is usually a metal label on the hinge edge of the door or on the frame. Someone quoting the work should be looking for it without being asked.
Who to call
A door closer sits in an awkward gap between trades, which is why this job is harder to price by phone than a lock change.
Commercial locksmiths fit and service closers, and so do commercial door companies, door hardware contractors and, in larger buildings, in-house maintenance. The work overlaps and the price lists do not. We looked at a published Toronto locksmith price list on 19 September 2026 and door closers do not appear on it at all. That same page, published by Matrix Locksmith, states that standard rates start at “$35 during regular hours” and “$119 after hours”, and that those ranges exclude a service fee it puts at “$35 to $90”. Published by the business and not verified by us.
The absence is the finding, not a criticism. A residential locksmith price list covers residential lock work, and a door closer on a rated commercial door is a different job for a different van. If you call a number off a lock-focused price list and get “we would have to come and look at it”, that is a reasonable answer to a question the list was never written to answer. The useful move is to say what the door is at the start of the call. Businesses that do service closers can say so on their own entry through our business listing form, which is where the service tags on this site come from.
Whoever you call, the price transparency question is the same one that applies across this trade. The Competition Bureau’s guidance on drip pricing describes it as “offering a product or service at a price that is unattainable because consumers must also pay additional charges or fees to buy the product or service”, and treats that as false or misleading under the law unless the extra charges are imposed by government, such as sales tax. Its plain-language version is the sentence to remember: “You shouldn’t have to scroll down or read the fine print to find the total price of an item.” That page is published by the Competition Bureau of Canada and we opened it on 19 September 2026.
What to ask before anyone books a visit
Six questions, and they are short on purpose. The first three establish what is being sold and the last three establish what it costs.
- Is this an adjustment or a replacement, and how will you tell which before you quote?
- Is the door fire rated, and will the closer you fit carry a rating that matches it?
- Does your price include the closer itself, or is the part billed separately?
- What is the service call or minimum charge if the fix turns out to be an adjustment?
- Is there an after-hours rate, and does it apply to the time I am asking for?
- Can I have the total in writing before you start, including tax?
The last one carries more weight than the other five together. A figure that grows on the doorstep was never the price of the job. A quote that answers question three in writing can be checked against the shelf price in the first table on this page. That is the only part of this transaction you can verify without leaving your desk.
What we could not establish
Being straight about the gaps is part of the method, and on this topic there are three worth naming.
We found no Canadian business publishing a price specifically for adjusting a door closer as its own line item. The figure above comes from a range covering closers, hinges, seals and latches together, which means a pure valve adjustment could sit well under it and we cannot say by how much.
We did not find a published price for the labour half on its own, separated from the part. Every installed figure we could open bundles them, which is exactly why question three on the list above exists.
We read one commercial door company’s published ranges and one locksmith price list, both on a single day, both in the same two cities those businesses serve. That is a small sample and a snapshot. A contractor in Winnipeg or Moncton may price this work in a unit we did not see, and prices published on a website can change the week after we read them. Anything we publish about a business carries the date we read it for that reason, and you can tell us when something has gone stale through our listing report form. What this directory does and does not claim to be is set out in our description of the project.
Common questions
Can a door closer be repaired, or does it always need replacing?
Both happen. A closer that has drifted out of adjustment is corrected at the valves and needs no parts. A closer that is leaking oil is a sealed hydraulic unit and is replaced rather than refilled. The diagnosis is the first thing to settle, because it is the difference between a service call and a service call plus hardware.
Why does my door close but not latch?
Most often the latch speed is set too low, so the door arrives at the frame without enough momentum to throw the latch. It can also mean the door or frame has moved and the latch no longer lines up with the strike. On a fire door this matters more than convenience, because the codes require positive latching and not merely closing.
Is a door closer required by law in Canada?
On a fire door, a self-closing device is required. Alberta’s fire door guidance, citing the National Building Code 2019 Alberta Edition, states that every fire door must have one along with a positive latching mechanism, and prohibits altering a fire door in any way that would prevent it operating as intended. Codes are administered province by province, so check the requirement that applies where the building is.
Can I replace a door closer myself?
On an ordinary interior or storm door, that is an ordinary hardware job and the parts are sold at retail. On a fire-rated door it is not a like-for-like swap. The replacement has to carry a rating that suits the assembly, and non-rated or incompatible hardware is one of the named ways a fire door stops doing its job.
Should I call a locksmith or a door company?
Either may do this work and the overlap is real. Say at the start of the call what kind of door it is, whether it is rated, and what the closer is doing wrong. That one sentence is what decides whether the right van turns up, and it is also what lets the business tell you honestly if the job is not theirs.
What to do next
Start by deciding which of the four failures you are looking at, because the slamming door and the leaking door lead to different invoices. Then look up the class of closer your door takes so you know what the part costs before anyone quotes the job. Then ask question three: is the part in the price. If the door is fire rated, say so in the first sentence of the call and ask what rating the replacement carries.
Our other cost guides for Canadian locksmith work apply the same method to keys, locks and lockouts, and the list of services businesses can be found under will tell you which trade to search for. When you are ready to find someone, our directory is organised geographically.
