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

Both springs were installed at the same time and have completed the same number of cycles in Perryville, AR. Metal fatigue accumulates proportionally to cycles under stress in Perryville. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Perryville, AR. The surviving spring is at essentially the same point in its fatigue progression in Perryville.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Perryville, AR. 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 Perryville. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Perryville, AR.
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 Perryville. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Perryville, AR. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Perryville. The specific reasoning is explained clearly in Perryville, AR. The homeowner makes the final decision with complete information in Perryville. Herlihy never withholds the reasoning or pressures the outcome in Perryville, AR.
