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

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