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

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