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

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