The London branch fits springs, cables, drums, rollers, hinges and seals on doors all over London, Ontario; opener parts are on the opener repair page. The parts page sorts them into those matched to one particular door and those a careful owner could fit. This page is about what the City expects of a door, who orders the part when whoever lives behind that door does not own it, and what happens to the hardware when a garage stops being one.
What London's by-law asks of a door
The City's Property Standards By-law, CP-24, enacted on May 25, 2021, holds each owner to repair and maintain the property to its standards, and it does not set garage doors apart. An opening designed for a door must have "a door, window, or skylight capable of performing the intended function". All doors "shall be maintained", and maintenance is spelled out: refitting, replacing or renewing damaged, decaying or defective doors, replacing or providing defective or missing hardware, and weatherstripping. Accessory buildings, a detached garage among them, "shall be maintained" unless they are unsafe.
Taken as a parts list, that is hinges, rollers, handles, locks and seals, and a door that no longer opens is hard to describe as performing its function. Mostly it calls for the part, fitted so the door works. Sections past saving are a replacement.
Rented houses near the campuses
Statistics Canada counted 73,100 London households renting their home in 2021. Western University reports 37,875 full-time students for September 2025 and Fanshawe College 21,000 at its main campus, and in 2024 the City raised the bedroom limit in its Near-Campus Neighbourhoods from 3 to 5. A house there can have 5 bedrooms behind the same garage door.
The City licenses rental units in buildings of up to 4 units under its Residential Rental Unit Licensing By-law, CP-19, and a new licence brings mandatory property standards and fire inspections. The owner is the person the by-law holds to its standards, so in a rented house the parts a homeowner might fit, a roller, a hinge or the weather seal, are the landlord's decision. Springs, cables and anything under spring tension are no one's but a technician's. A booking for a rental should carry the owner's name and the tenant's phone, so the visit is arranged with the person at home.
When the garage becomes a unit
The City's 2024 amendments allow up to 3 extra residential units on a lot where the zoning permits, and up to 2 of them in an accessory building, the category a detached garage falls in. A conversion that closes the opening takes the door out, and the order matters. The springs are unwound and the cables slackened by a technician before anyone unbolts a bottom bracket, because those brackets sit under full cable tension while the springs are wound. Ask the branch about taking the door down at the start of the conversion, not once the framers find it.
A visit to Farnham Road
Customers are received at 1003 Farnham Rd in Westmount, N6K 1S3, by arrangement, so call first. A part is matched from its label and a photo of the door, sent ahead. Springs and cables stay on the door, and spring repair is always a visit to the house.
What to send
An image of the failed part, one of the manufacturer's label, the door width and the address. Say who owns the door, you or a landlord, with the owner's contact, and mention a conversion if one is coming. Repairs are booked the same day. Send the contact form, email info@protechgarage.ca or call (226) 270-9715.

Answered for London, on the number this branch answers.
Does the City of London require a garage door that no longer works to be repaired?
The Property Standards By-law, CP-24, covers all doors, not just the front door. It requires an opening designed for a door to have one capable of performing its intended function, lists replacing defective or missing hardware as maintenance, and requires accessory buildings, detached garages among them, to be maintained unless unsafe. It is the owner the by-law holds to that, so the part is the owner's call.
I rent a house near Western. Can I swap a roller myself?
Ask the landlord first. A roller, a hinge or the weather seal is manageable for a careful owner, but in a rented house the owner is the person the City's property standards by-law holds responsible, and a new rental licence in London starts with property standards and fire inspections. Springs, cables and anything under spring tension are not a job for a tenant or an owner.
We are turning the detached garage into a unit. Can our contractor just take the door out?
Not while the springs are wound. The bottom brackets sit under full cable tension, and a bracket unbolted on a wound door lets that tension go at once. A technician unwinds the springs and slackens the cables first, and the door comes down in order after that. London allows up to 2 extra units in an accessory building, so this comes up; make the removal the conversion's first job.
