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

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