The One Home Repair Where Paying a Professional Is Buying Safety, Not Convenience
A garage door torsion spring is the part that sends people to hospital.
In short
Most garage door repairs in the GTA are $200–450 all-in after a $90–150 service call. A torsion spring is $250–500 for one, $350–650 for a matched pair. A new opener installed is $450–900; a new double door, $1,800–4,000.
Two things are worth knowing before you call anyone. First: garage door work is not a compulsory trade in Ontario. There is no certificate of qualification to ask for, and anyone may advertise the service.
Second: the torsion spring holds enough stored energy to injure seriously if it is handled wrong. It is the one repair in this category that is genuinely not a homeowner job — and the one most often attempted anyway, because the part looks cheap online.
What garage door work costs
Market quotes, autumn 2026 — prices published by GTA businesses that sell the work, not an independent survey.
| Job | Typical price | Notes |
|---|---|---|
| Service call / diagnosis | $90–150 | Ask whether it is credited against the repair |
| Rollers, hinges, minor hardware | $150–300 | Often bundled into a tune-up |
| Cable replacement | $150–350 | Frequently fails alongside a spring |
| Torsion spring, one | $250–500 | Includes the part and the winding |
| Torsion spring, matched pair | $350–650 | Cheaper than two separate visits |
| Track realignment | $150–400 | A bent track is usually an impact, not wear |
| Opener replacement, installed | $450–900 | Belt drive costs more and is far quieter |
| New single door, installed | $1,200–2,500 | Confirm removal and disposal of the old one |
| New double door, installed | $1,800–4,000 | Insulated and carriage styles at the top end |
Why the spring is different from everything else
A garage door weighs far more than it feels like, because the springs carry almost all of it. A torsion spring sits wound above the door under very high tension, and that tension is what lifts a hundred-plus kilograms with one hand.
Release it without the right winding bars and the right technique and it unwinds violently. This is not a general warning attached to a routine job — spring replacement is the specific repair with a long record of serious hand, face and head injuries among people who watched a video first.
The rest of the door is a different matter. Sensors, lubrication, weatherstripping, even a roller are ordinary maintenance. The spring is the line, and it is worth knowing exactly where that line sits.
There is no licence to check — so check the rest
Electrical work has the Skilled Trades Ontario register; gas appliances have TSSA. Garage doors have neither. Nobody has to prove anything to advertise this service in Ontario.
Which shifts all the weight onto the ordinary checks: a written quote, liability insurance, WSIB clearance, and a company with an address. Our guide on what “licensed and insured” actually means covers how to verify those in about fifteen minutes.
Three things to try before you call
Each takes minutes and each resolves a common call-out.

What to do next
Do the balance test this week: disconnect the opener, lift the door halfway, let go. If it does not stay, book the spring work now rather than on the morning it breaks with your car inside.

Frequently asked questions
A service call typically runs $90 to $150, with common repairs landing at $200 to $450 all-in: rollers, cables, a broken hinge or realignment. Torsion spring replacement is usually $250 to $500 for one spring and $350 to $650 for a pair, and opener replacement commonly runs $450 to $900 installed.
A standard single door supplied and installed generally runs $1,200 to $2,500, and a double door $1,800 to $4,000, with insulated and carriage-style doors at the upper end. Removal and disposal of the old door should be a stated line on the quote, not an assumption.
Because a torsion spring stores a great deal of energy and releases it violently if it is handled wrong. It is the one part of a garage door that regularly injures people, and the winding bars and technique are not intuitive. This is the rare home repair where the professional price is genuinely buying safety rather than convenience.
No. Garage door installation and repair is not a compulsory trade, so there is no certificate of qualification to ask for and anyone may advertise the service. That makes the ordinary checks more important, not less — liability insurance, WSIB clearance, a written quote and references.
If they are a matched pair of the same age, yes. Springs are rated by cycles and fail within a similar window, so replacing one leaves you paying a second service call shortly afterwards. Replacing a pair together also keeps the door balanced, which is what protects the opener.
Most often the safety sensors near the floor are misaligned, blocked or dirty — a two-minute fix you can try yourself before calling anyone. If the sensors are clean and aligned and the door still reverses, the door is likely out of balance or binding in the tracks, which is a real repair.
An annual tune-up is the common recommendation: lubrication, balance check, hardware tightening and a sensor test. On a door used several times a day it is worth it, because most expensive failures announce themselves first as noise, sag or a door that no longer holds halfway when lifted by hand.
Sources and how current this is
Checked 18 September 2026. Prices are market quotes published by GTA businesses that sell the work, not an independent survey, and they move. That garage door installation and repair is not a compulsory trade in Ontario means there is no certificate of qualification for it; compulsory trades and their certification are administered by Skilled Trades Ontario, and this work is not among them. The description of torsion spring hazard reflects the manufacturer and industry consensus that winding and unwinding requires proper tools and training; this page is not a repair manual and deliberately does not describe how to do it. Checks on insurance and WSIB coverage follow the WSIB clearance process. Ontario24 is a classified directory and does not repair doors or vet the businesses listed.
