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

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