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

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