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

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