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

Opener disconnected. Door manually lifted to halfway position in Crescent, OK. Door released and observed in Crescent. Holds at halfway — specification confirmed correct in Crescent, OK. Rises — oversprung, winding adjusted in Crescent. Drops — undersprung, winding adjusted in Crescent, OK. Opener reconnected only after balance test confirms correct specification in Crescent.
Both springs were installed at the same time and have completed the same number of cycles in Crescent, OK. Metal fatigue accumulates proportionally to cycles under stress in Crescent. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Crescent, OK. The surviving spring is at essentially the same point in its fatigue progression in Crescent.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Crescent, OK. 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 Crescent. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Crescent, OK.
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 Crescent. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Crescent, OK. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Crescent. The specific reasoning is explained clearly in Crescent, OK. The homeowner makes the final decision with complete information in Crescent. Herlihy never withholds the reasoning or pressures the outcome in Crescent, OK.
