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

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