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

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