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

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