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

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