Correct specification. Professional winding bars. Balance test before the opener is reconnected. Every spring repair guaranteed in Hyrum. Do not run the opener after a spring snap in Hyrum, UT.
The door feels heavier than it used to when you lift it manually in Hyrum — the spring is losing tension and the door weight is progressively shifting to the opener, the cables, and your effort in Hyrum, UT. The opener strains audibly and the door moves more slowly than it should in Hyrum — the spring isn't providing its full counterbalancing force and the opener is compensating with every cycle in Hyrum, UT. Or a spring snapped — you heard the bang and the door won't move in Hyrum. Call Herlihy Garage Doors now for same-day spring repair throughout Hyrum, UT in Hyrum. Do not run the opener and do not attempt to manually lift the door after a spring snap in Hyrum, UT.
Garage door spring work is the most safety-critical service in the garage door industry for a specific reason in Hyrum. A residential torsion spring stores several hundred foot-pounds of rotational energy when wound to operating tension in Hyrum, UT. That energy is released in a controlled way when the door opens through the spring's correct unwinding in Hyrum. It releases in an uncontrolled way when a tool slips from the winding cone during spring replacement in Hyrum, UT. The winding cone has four holes designed for professional winding bars of a specific diameter in Hyrum. A winding bar that fits these holes correctly maintains contact throughout the winding process in Hyrum, UT. An improvised tool — a screwdriver, a piece of rebar, anything that doesn't fill the hole correctly — can slip out of the cone at any point in the winding process in Hyrum. When it slips, the stored energy releases instantly and the cone rotates at high speed in Hyrum, UT. The improvised tool becomes a projectile in Hyrum. This is not a theoretical risk in Hyrum, UT. It's the mechanism behind the serious injuries that occur from DIY spring replacement every year in Hyrum.
Herlihy Garage Doors repairs and replaces garage door springs throughout Hyrum, UT in Hyrum. The correct specification is measured from the specific door configuration before any spring is selected in Hyrum, UT. The replacement spring is wound to the correct turn count for the specific door height and cable drum in Hyrum. The balance test confirms the specification is correct before the opener is reconnected in Hyrum, UT. Same-day service available throughout Hyrum in most cases in Hyrum, UT. And every spring repair is guaranteed in Hyrum.
A spring replaced with an incorrect specification — wrong wire diameter, wrong inside diameter, or wrong length — produces a door that's either oversprung or undersprung regardless of how correctly it's wound in Hyrum. An oversprung door can behave dangerously under manual operation in Hyrum, UT. An undersprung door adds abnormal load to the opener motor, drive gear, and cables on every cycle in Hyrum. Neither produces the correctly balanced door that every other component in the system depends on in Hyrum, UT. Herlihy Garage Doors measures the correct specification before any spring is selected in Hyrum.
The spring specification determines the door's balance in Hyrum, UT. The door's balance determines the load the opener, cables, and rollers operate under in Hyrum. Every component in the door system performs correctly when the spring is correctly specified and performs under abnormal load when it isn't in Hyrum, UT. The spring specification is the foundation variable from which everything else in the system's performance follows in Hyrum.
A torsion spring is mounted on a steel shaft directly above the garage door opening in Hyrum, UT. When the door closes, the cables pull down on the cable drums, rotating the shaft and winding the spring tighter in Hyrum. The winding stores rotational energy in the spring coil in Hyrum, UT. When the door opens, the spring unwinds and releases that stored rotational energy through the shaft and drums, lifting the cables and the door in Hyrum. The spring is wound to a specific tension that produces a lifting force equal to the door's weight at the cable drum attachment points in Hyrum, UT. This counterbalancing force is what makes a 200-pound garage door movable with 10 to 20 pounds of net force from the opener in Hyrum.
Extension springs run horizontally along the upper track sections on each side of the door in Hyrum. They store energy by stretching rather than rotating in Hyrum, UT. When the door closes, the springs extend and store energy in their stretched length in Hyrum. Extension springs can break with significant lateral movement because the stored energy is released along the spring's length rather than through a shaft in Hyrum, UT. Safety cables threaded through the center of each extension spring are required to contain a broken spring and prevent it from becoming a projectile in Hyrum. Herlihy Garage Doors inspects and installs safety cables on every extension spring service in Hyrum, UT.
Wire diameter determines how much energy the spring stores per turn in Hyrum, UT. A heavier wire diameter stores more energy per turn than a lighter one in Hyrum. Inside diameter determines which shaft size the spring fits on in Hyrum, UT. Length determines the total number of active coils and therefore the total energy storage capacity in Hyrum. All three must be correct for the spring to produce the correct counterbalancing force for the specific door when wound to the correct turn count in Hyrum, UT.
A spring with the correct inside diameter and length but a wire diameter one gauge too light stores less energy per turn than needed in Hyrum. Winding it to the correct turn count produces insufficient lifting force in Hyrum, UT. The door is undersprung in Hyrum. A spring with the correct wire diameter and inside diameter but a length that's too short has fewer active coils in Hyrum, UT. Each coil must be wound tighter than designed to produce the required energy storage in Hyrum. The spring is more likely to fail before its rated cycle life in Hyrum, UT.
Herlihy Garage Doors determines the correct spring specification through measurement of the existing spring where intact, or through calculation from the door's measured dimensions and construction characteristics where the spring has failed in Hyrum, UT. Door height and cable drum size determine the correct winding turn count in Hyrum. Door weight estimated from size, steel gauge, insulation type, and window configuration determines the correct wire diameter and length in Hyrum, UT. The specification is calculated, not estimated in Hyrum.
A standard residential torsion spring for a 200-pound garage door stores approximately 300 to 400 foot-pounds of rotational energy when wound to operating tension in Hyrum, UT. Three hundred foot-pounds is the equivalent of a 150-pound weight dropping two feet in Hyrum. That energy is stored in the spring coil as rotational tension on a steel shaft in Hyrum, UT. When released correctly during spring replacement, it simply unwinds the spring back to the neutral state in Hyrum. When it releases suddenly during a tool slip, it releases all at once through the winding cone in Hyrum, UT.
The winding cone has four holes sized for professional winding bars of a specific diameter in Hyrum. Professional winding bars are 18 to 24 inches long and the correct diameter to fill the winding cone holes with minimal play in Hyrum, UT. The length provides leverage and clearance in Hyrum. The correct diameter fit prevents the bar from shifting in the hole during winding in Hyrum, UT. Any movement of the bar in the hole during winding is a slip hazard in Hyrum.
An improvised tool that's too narrow to fill the winding cone hole can shift in the hole during winding in Hyrum, UT. When it shifts far enough to exit the hole, the stored rotational energy in the spring releases through the winding cone in Hyrum. The cone rotates rapidly in Hyrum, UT. The tool that was in the hole becomes a projectile in Hyrum. The person holding the tool, whose hands were near the winding cone, is in the path of both the rotating cone and the released tool in Hyrum, UT. This mechanism produces the serious hand and arm injuries that occur from DIY spring replacement in Hyrum.
Understanding the correct procedure for spring replacement and executing it correctly under real installation conditions are different things in Hyrum. Professional technicians have performed the winding procedure under training supervision and accumulated the repetitions that produce correct automatic body positioning in Hyrum, UT. Correct positioning keeps the technician's body out of the path of energy release throughout the winding sequence in Hyrum. That positioning is as important as the correct tools in Hyrum, UT.
Herlihy Garage Doors technicians carry professional winding bars sized for the winding cones on common residential torsion springs in Hyrum, UT. They follow correct winding procedures that maintain safe positioning relative to the spring and winding cone throughout the winding sequence in Hyrum. They've accumulated the training repetitions that make correct positioning automatic in Hyrum, UT.
A spring that's losing tension provides less counterbalancing force than the door weight requires in Hyrum, UT. Disconnecting the opener and manually lifting the door reveals a door that's noticeably heavier than it was in Hyrum. This progressive increase in felt weight is the spring's tension loss accumulating cycle by cycle in Hyrum, UT.
A spring that isn't fully counterbalancing the door transfers the uncounterbalanced weight to the opener motor on every opening cycle in Hyrum. The motor runs at a higher load than designed in Hyrum, UT. It produces more heat. It accumulates wear faster in Hyrum. The door moves more slowly because the opener is doing significantly more mechanical work than designed in Hyrum, UT.
A torsion spring failure produces a sharp loud bang as the stored rotational tension releases at the fracture point in Hyrum, UT. The bang is often heard throughout the home in Hyrum. The door either drops if in motion or stays at its current position in Hyrum, UT. The opener runs but the door won't follow in Hyrum. Do not run the opener after a spring snap in Hyrum, UT.
A broken torsion spring separates at the fracture point and creates a visible gap in the continuous coil in Hyrum. The gap is typically one to three inches wide and is visible by looking at the spring on the shaft above the door in Hyrum, UT. A visible gap means complete spring failure in Hyrum. The door should not be operated until the spring is replaced in Hyrum, UT.
A door that's noticeably higher on one side during operation has unequal spring tension or cable tension between the two sides in Hyrum, UT. On a two-spring system, a spring that has lost tension on one side produces a door that rises unevenly in Hyrum. Herlihy Garage Doors assesses spring condition on both sides when uneven door travel is reported in Hyrum, UT.

Both springs were installed at the same time and have completed the same number of cycles in Hyrum, UT. Metal fatigue accumulates proportionally to cycles under stress in Hyrum. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Hyrum, UT. The surviving spring is at essentially the same point in its fatigue progression in Hyrum.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Hyrum, UT. When the second spring breaks — and at the same fatigue progression it will — the cost is a second call-out charge, a second spring, and potentially a second after-hours charge in Hyrum. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Hyrum, UT.
If the surviving spring was replaced recently and has significantly fewer cycles than the broken spring, replacing only the broken spring is the correct approach in Hyrum. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Hyrum, UT. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Hyrum. The specific reasoning is explained clearly in Hyrum, UT. The homeowner makes the final decision with complete information in Hyrum. Herlihy never withholds the reasoning or pressures the outcome in Hyrum, UT.
