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

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