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

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