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

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