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

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