Garage Door Spring Replacement
Failed springs replaced in matched pairs and re-tensioned to the actual door weight.

Counterbalance corrected on intact springs so a wide door lifts level again.
What's involved
Garage Door Spring Repair
Spring work splits into two different jobs that get used interchangeably. Repair means adjustment, re-tensioning, attention to the hardware around the spring, and correcting a balance that has drifted, and it applies where the spring itself is still sound. Replacement applies once the coil has broken, corroded or run out of useful cycle life. Balance drift turns up often in Burlington because so many doors are wide doubles: on a wide leaf a small tension error produces a visibly uneven lift, and any change in door weight has more effect than it would on a narrow single.

Symptoms
Signs You Need This Service
- The door feels much heavier by hand than it used to.
- Raised halfway, the door creeps up or drifts down instead of staying put.
- The opener strains, hums, or reverses shortly after starting to lift.
- One side of a wide door leads the other and the leaf rises crooked.
- The door drops the last few inches instead of settling gently.
Repair or replace?
Springs are rated in cycles rather than in years, so a door opened six times a day uses up its allowance far faster than one opened twice, and a household that treats the garage as its main entrance, common in the Brantwell bungalofts of Tansley Woods, gets through cycles quickly. Adjustment does not put cycles back; it restores a correct setting on a spring that still has life in it. Where a coil shows separation, rust pitting or a measurable loss of output, adjusting it only defers a failure to a less convenient moment. We describe the condition found rather than quoting a generic number of years.

Root causes
What Actually Goes Wrong
Tension no longer matches door weight
Springs are set for a specific weight. A replaced section, added insulation, a heavier bottom seal or a new glazed insert all change that weight, and the original setting stops being correct.
Cycles and cold have reduced output
A spring loses a little torque as cycles accumulate, and cold stiffens everything around it. A door that was marginal in October can be plainly unbalanced on a January morning.
Hardware around the spring has shifted
A loose centre bearing plate, a slipped cone, worn end bearings or a drum that has crept along the shaft all change effective tension without the spring itself having failed.
The two sides are uneven
On a two-spring double, uneven settings or one coil further through its life than the other make the leaf lift out of square and load one track and one set of rollers far harder than the other.
Local conditions
Why This Matters in Burlington
Width is the Burlington factor. Tyandaga is described locally as large properties with mature streets and double-lane driveways where most homes have a double garage, Headon Forest was built with attached single- or double-car garages on lots of about 50 by 100 feet, and Millcroft homes tend to have double-car garages set back off the street. On a wide leaf, correct counterbalance is not a nicety: it is what keeps the door square in its tracks. In the townhouse-dominated parts of the city, Uptown with no detached homes at all and Tansley Woods with 41 percent low-rise condominium and 40 percent row housing, doors are narrow and light, and a suspected spring fault more often turns out to be an operator or roller problem.
Safety
What to Handle Yourself
Torsion springs store enough energy to cause serious injury and must be wound and unwound with proper winding bars, never with screwdrivers or improvised tools. Extension springs need containment cables so a broken coil cannot travel across the garage. Nothing in a spring system should be adjusted while the door is unsupported, and cable drums and bottom brackets remain under tension even with the door fully open. This is the part of a garage door where a small error produces a large consequence, and it is the part we would most strongly discourage anyone from experimenting with.
The visit
How We Work Through It
-
Read the door by hand
With the operator disconnected the door is lifted under control and tested at several heights. Its weight, its behaviour at the midpoint and whether it stays where it is left tell us what the spring is really doing.
-
Inspect the whole assembly
Coil condition, gaps, cone seating, the shaft, centre and end bearings and drum position are all examined. Visible separation or heavy pitting makes a spring a replacement candidate, not an adjustment candidate.
-
Adjust, or say it plainly
Where the spring is sound, tension is adjusted in measured increments with the door retested by hand between them. Where it is not, we say so rather than chasing balance on a coil that is finished.
-
Confirm and reconnect
Level travel, equal cable tension on both sides and settled behaviour at rest are checked before the operator goes back on, and then its force settings and safety reversal are verified.
Questions
Garage Door Spring Repair FAQs
How can I tell if my door needs adjustment or new springs?
Start with the visible condition of the coil. A clean spring with no gap, no separation and no heavy pitting, on a door that has simply lost its balance, is often an adjustment. A coil with a visible break, a gap between windings or significant corrosion is a replacement. Weighing the door and reading how it behaves by hand confirms which case you are actually in, and that test takes minutes.
Can tension be increased so the opener has an easier time?
Correct balance is exactly what makes a door easy for an operator, so in that sense yes: proper tension removes load the motor should never have been carrying. What adjustment cannot do is compensate for a leaf that is heavier than the spring was ever sized for. On a wide double that has had sections replaced or insulation added, the honest answer is usually a spring matched to the door's real weight.
Why is my door fine in summer and heavy in winter?
Cold affects the whole assembly at once. Grease thickens, steel contracts slightly, rollers and bearings turn less freely, and a spring already near the limit of its output has less margin left. With a January daily mean of minus 4.4 degrees and an average January high of minus 0.6, an unheated Burlington garage crosses the freezing point regularly, so a door that was borderline becomes obviously unbalanced.
If only one spring is a problem, should both be dealt with?
On a two-spring door, usually yes. Both coils have taken the same cycles under the same load, so when one has drifted or failed the other is rarely far behind, and on a wide double an uneven pair makes the leaf rack in its tracks. Doing both keeps the lift even and avoids a second visit weeks later. Where one spring is genuinely much newer, we will tell you.
