Garage Door Spring Repair Milton

Torsion vs. Extension Springs: A Milton Homeowner's Guide

Garage door springs are the workhorses of the entire system, counterbalancing up to 400 lbs of door weight so your opener motor only has to guide, not lift. In Milton, where humid continental, escarpment location means higher snowfall than surrounding areas, springs face additional stress from thermal cycling — metal contracts in winter and expands in summer, gradually fatiguing the coils. Understanding which type of spring your door uses, and when to replace it, can save you an emergency call and a blocked garage at the worst possible moment.

Torsion Springs: The Modern Standard

Torsion springs mount horizontally on a steel shaft above the door opening and store energy by twisting. They are the preferred system in Milton for several reasons: they distribute load evenly across both sides of the door, they break more predictably (the door simply stops rather than crashing), and they last significantly longer — standard springs are rated for 10,000 cycles, while our high-cycle upgrades reach 25,000–50,000 cycles. At an average of four door cycles per day, a 25,000-cycle spring lasts approximately 17 years.

Spring sizing is critical. The correct spring is calculated by door height, width, weight, and the number of turns required to fully lift the door. An undersized spring causes the opener to overwork; an oversized spring causes the door to fly open dangerously. Our technicians carry over 40 spring sizes to ensure an exact match on the first visit.

Extension Springs: Older Homes and Smaller Garages

Extension springs run parallel to the horizontal tracks and stretch as the door closes. Many Milton homes built before 1990 — particularly in Scott and Willmott — still have extension spring systems. These work well when properly maintained, but they require safety cables threaded through the spring coils; without them a broken spring can launch across the garage with dangerous force.

Warning Signs a Spring Is Near Failure

• Door feels unusually heavy when lifted manually — spring has lost tension
• Door rises unevenly, one side higher than the other — one spring weakening
• Loud bang from the garage, often at night as temperatures drop — spring snapped
• Visible gaps in the spring coil — coil separation indicating failure
• Spring shows surface rust or orange discolouration — corrosion weakening the steel
• Opener strains audibly and moves slower than usual — spring no longer counterbalancing

Milton is Canada's fastest-growing town, with most homes built after 2005 featuring modern garage door systems. For homes throughout Scott, Timberlea, Old Milton, Harrison, Beaty, Willmott, we strongly recommend replacing both springs simultaneously even if only one has broken — the second spring has endured the same cycle count and will fail within weeks. Our double-spring package includes replacement of both springs, proper balancing, cable inspection, and a full safety check, saving you a second service call and providing even wear going forward.
