Replacing One Spring Now Costs You Twice
Paired spring replacement - done right - means you won't pay for a second service call in six months.
Paired spring replacement is the practice of replacing both springs at the same time on a two-spring torsion system. It's the decision that separates a short-term fix from a long-term result. Both springs were installed on the same day. They've completed the identical number of open-close cycles. When one breaks, the other carries the same fatigue load - just moments behind.
Replacing only the broken spring leaves a worn spring in place on the other side. When springs are installed simultaneously, they wear at the same rate. That surviving spring will typically fail within weeks or months. Your door goes down again. Another service call. Another labor charge. Another disruption.
Hearth's full garage door spring replacement service in Boise addresses both sides in one visit - not because it's easier, but because the math doesn't lie.

Boise's Climate Puts More Stress on Your Springs Than You'd Expect
Desert heat, cold snaps, and wide temperature swings accelerate spring fatigue in the Treasure Valley.
Boise runs through significant seasonal temperature swings - from summer highs pushing 100°F down to hard freezes in January. That range stresses metal repeatedly through expansion and contraction. Springs that might last a decade in a stable climate cycle faster here.
Mountain Home and Twin Falls fall within Hearth's service area. Spring replacement calls in those communities are handled by the same Boise team - no referral, no handoff, no delay. The same crew that replaces springs on a door in the Depot District drives out to handle a door in Mountain Home without a scheduling gap. Whether your garage faces west into the afternoon sun near Nampa or sits in an east-facing bay in Caldwell, the spring spec accounts for actual local use - not a generic industry average.

What a Paired Replacement Actually Looks Like in the Field
Every replace garage door spring Boise call starts with the door weight, not the broken spring.
Both had hit their limit at almost exactly the same time.
Hearth Garage Doors Service Team, Boise
I've pulled up to a house in Meridian where the homeowner had already called once before - about eight months earlier. The original visit replaced one spring. By the time I arrived, the second spring had snapped at 4 a.m. The door was frozen at the floor. The owner had to leave for work with the garage inaccessible and a vehicle inside.
When I pulled the door's history - based on spring diameter, wire gauge, and visible coil count - those springs had been 10,000-cycle units on a door running about five cycles a day. That's a roughly five-to-six-year lifespan. Both had hit their limit at almost exactly the same time. The first just gave out weeks earlier than the second.
We replaced both springs that visit. I also walked the homeowner through the spring torque calculation - the mathematical sizing process that matches wire diameter, inside diameter, and spring length to the actual measured weight of the door. That number matters more than the original spring's visual appearance. We sized up to 25,000-cycle oil-tempered wire springs. Oil-tempered wire is treated through a heat and oil process that increases tensile strength and fatigue resistance over standard galvanized wire - especially under the repeated temperature cycling common in the Boise area.
That door won't need spring attention again for well over a decade at current use rates.

Your Cycle Count Is the Only Real Measure of Spring Life
Spring cycle count - the cumulative number of open-close operations since install - is the number that matters.
Cycle count isn't visible. Springs don't show cracks before they snap. They don't sag or change color. The only way to understand remaining service life is to know how many cycles have already been completed and what the spring was rated for at install.
Hearth walks through those numbers with you before any spring goes on the door. A garage running four cycles per day - two opens, two closes - logs about 1,460 cycles per year. A 10,000-cycle spring lasts roughly six to seven years at that rate. A 25,000-cycle spring lasts closer to seventeen years. The 100,000-cycle option is built for commercial-grade demand or homeowners who want decades of reliable operation without revisiting the decision.
The cost difference between spring grades is a fraction of a second service call. Choosing a cycle rating matched to your actual daily use isn't a premium - it's arithmetic.

Our Spring Replacement Standards
New garage door spring installation in Boise follows wire type, torque, and compatibility standards - every time.
Wire type selectionOil-tempered wire for high-cycle or high-stress applications. Galvanized wire - zinc-coated for surface corrosion resistance - for standard residential use with moderate cycle counts.
Spring torque calculationEvery replacement is sized to the measured door weight. Correct torque produces balanced lift without overloading the opener motor.
Drum and cable compatibilityReplacement spring specifications are verified against the existing cable drum diameter and cable length. Drum and cable compatibility - the requirement that spring torque aligns with drum geometry - prevents unequal cable tension across the system.
Both springs replaced simultaneouslyOn two-spring torsion systems, both units are replaced in one visit without exception.
Post-install balance testThe door is manually balanced and tested under opener load before the job is closed.
The cost difference between spring grades is a fraction of a second service call.
How the Spring Replacement Process Works
A full spring swap Boise Idaho service call follows a consistent three-stage protocol.
Measure First, Remove Second
The technician measures the door's actual weight using a lift test - the door is manually raised to the halfway point and released. A balanced door holds position. An unbalanced door reveals spring torque errors before any hardware is removed. Wire diameter, coil count, and inside diameter of the existing springs are recorded to confirm current torque values and identify any prior upsizing or downsizing.
Installing Both Springs to Spec
Both springs are removed. New springs are wound to the torque value calculated for the door's confirmed weight. Cable drums are inspected for groove wear before cables are re-tensioned. On systems where galvanized wire springs have corroded at the winding cone - common on older Boise homes with no garage climate control - the winding cones are replaced, not just cleaned.
Verifying the Full System Before Closing
The door runs through five full open-close cycles under opener load. Manual balance is re-checked at the midpoint. Cable tension is confirmed equal on both sides. The technician verifies that the opener's force settings haven't shifted due to the spring change - a step that's easy to skip and costly when missed.

Frequently Asked Questions
Spring snapped? Call 208-295-4245.
Yes - paired replacement costs more upfront than a single-spring swap. The difference is typically one additional spring and a few minutes of labor. Compare that to a second full service call when the surviving spring fails weeks later. Replacing both in one visit eliminates that second charge. Most homeowners spend less overall by doing it right the first time.
Most paired spring replacements finish in 60 to 90 minutes. That includes measuring door weight, removing both old springs, winding and installing new springs to the correct torque, re-tensioning cables, and running five full test cycles. Doors with corroded winding cones or worn cable drums may add 20 to 30 minutes.
Cycle rating determines how many open-close operations a spring survives before failure. At four daily cycles, a 10,000-cycle spring lasts roughly seven years. A 100,000-cycle spring on that same door lasts over 60 years. The cost gap between grades is far smaller than the cost of repeated replacements. Choose based on your actual daily usage, not the cheapest available option.
Matching size assumes the previous spring was correctly sized - and many aren't. The right spring torque is calculated from the door's actual measured weight, not from what was installed before. An incorrectly torqued spring strains the opener motor and produces uneven cable tension across both drums. Sizing from weight protects the full system, not just the springs.
Oil-tempered springs are available on every Boise replacement job Hearth handles. Oil-tempering is a heat-and-oil treatment that increases tensile strength and fatigue resistance. Standard galvanized wire has a zinc coating that resists surface rust but fatigues faster under repeated cycling. For doors running in temperature-variable conditions - common across the Treasure Valley - oil-tempered wire holds up longer under the same load.
Worn drums and corroded winding cones are replaced during the same visit, not deferred to a later call. A new spring paired with a damaged drum produces unequal cable tension. That imbalance transfers load to the opener and causes premature failure in both the spring and the motor. Every spring replacement includes a drum and cone inspection before the new springs are wound.
