Correct specification. Professional winding bars. Balance test before the opener is reconnected. Every spring repair guaranteed in Branchville. Do not run the opener after a spring snap in Branchville, SC.
The door feels heavier than it used to when you lift it manually in Branchville — the spring is losing tension and the door weight is progressively shifting to the opener, the cables, and your effort in Branchville, SC. The opener strains audibly and the door moves more slowly than it should in Branchville — the spring isn't providing its full counterbalancing force and the opener is compensating with every cycle in Branchville, SC. Or a spring snapped — you heard the bang and the door won't move in Branchville. Call Herlihy Garage Doors now for same-day spring repair throughout Branchville, SC in Branchville. Do not run the opener and do not attempt to manually lift the door after a spring snap in Branchville, SC.
Garage door spring work is the most safety-critical service in the garage door industry for a specific reason in Branchville. A residential torsion spring stores several hundred foot-pounds of rotational energy when wound to operating tension in Branchville, SC. That energy is released in a controlled way when the door opens through the spring's correct unwinding in Branchville. It releases in an uncontrolled way when a tool slips from the winding cone during spring replacement in Branchville, SC. The winding cone has four holes designed for professional winding bars of a specific diameter in Branchville. A winding bar that fits these holes correctly maintains contact throughout the winding process in Branchville, SC. 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 Branchville. When it slips, the stored energy releases instantly and the cone rotates at high speed in Branchville, SC. The improvised tool becomes a projectile in Branchville. This is not a theoretical risk in Branchville, SC. It's the mechanism behind the serious injuries that occur from DIY spring replacement every year in Branchville.
Herlihy Garage Doors repairs and replaces garage door springs throughout Branchville, SC in Branchville. The correct specification is measured from the specific door configuration before any spring is selected in Branchville, SC. The replacement spring is wound to the correct turn count for the specific door height and cable drum in Branchville. The balance test confirms the specification is correct before the opener is reconnected in Branchville, SC. Same-day service available throughout Branchville in most cases in Branchville, SC. And every spring repair is guaranteed in Branchville.
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 Branchville. An oversprung door can behave dangerously under manual operation in Branchville, SC. An undersprung door adds abnormal load to the opener motor, drive gear, and cables on every cycle in Branchville. Neither produces the correctly balanced door that every other component in the system depends on in Branchville, SC. Herlihy Garage Doors measures the correct specification before any spring is selected in Branchville.
The spring specification determines the door's balance in Branchville, SC. The door's balance determines the load the opener, cables, and rollers operate under in Branchville. Every component in the door system performs correctly when the spring is correctly specified and performs under abnormal load when it isn't in Branchville, SC. The spring specification is the foundation variable from which everything else in the system's performance follows in Branchville.
A torsion spring is mounted on a steel shaft directly above the garage door opening in Branchville, SC. When the door closes, the cables pull down on the cable drums, rotating the shaft and winding the spring tighter in Branchville. The winding stores rotational energy in the spring coil in Branchville, SC. 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 Branchville. 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 Branchville, SC. This counterbalancing force is what makes a 200-pound garage door movable with 10 to 20 pounds of net force from the opener in Branchville.
Extension springs run horizontally along the upper track sections on each side of the door in Branchville. They store energy by stretching rather than rotating in Branchville, SC. When the door closes, the springs extend and store energy in their stretched length in Branchville. 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 Branchville, SC. 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 Branchville. Herlihy Garage Doors inspects and installs safety cables on every extension spring service in Branchville, SC.
Wire diameter determines how much energy the spring stores per turn in Branchville, SC. A heavier wire diameter stores more energy per turn than a lighter one in Branchville. Inside diameter determines which shaft size the spring fits on in Branchville, SC. Length determines the total number of active coils and therefore the total energy storage capacity in Branchville. 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 Branchville, SC.
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 Branchville. Winding it to the correct turn count produces insufficient lifting force in Branchville, SC. The door is undersprung in Branchville. A spring with the correct wire diameter and inside diameter but a length that's too short has fewer active coils in Branchville, SC. Each coil must be wound tighter than designed to produce the required energy storage in Branchville. The spring is more likely to fail before its rated cycle life in Branchville, SC.
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 Branchville, SC. Door height and cable drum size determine the correct winding turn count in Branchville. Door weight estimated from size, steel gauge, insulation type, and window configuration determines the correct wire diameter and length in Branchville, SC. The specification is calculated, not estimated in Branchville.
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 Branchville, SC. Three hundred foot-pounds is the equivalent of a 150-pound weight dropping two feet in Branchville. That energy is stored in the spring coil as rotational tension on a steel shaft in Branchville, SC. When released correctly during spring replacement, it simply unwinds the spring back to the neutral state in Branchville. When it releases suddenly during a tool slip, it releases all at once through the winding cone in Branchville, SC.
The winding cone has four holes sized for professional winding bars of a specific diameter in Branchville. Professional winding bars are 18 to 24 inches long and the correct diameter to fill the winding cone holes with minimal play in Branchville, SC. The length provides leverage and clearance in Branchville. The correct diameter fit prevents the bar from shifting in the hole during winding in Branchville, SC. Any movement of the bar in the hole during winding is a slip hazard in Branchville.
An improvised tool that's too narrow to fill the winding cone hole can shift in the hole during winding in Branchville, SC. When it shifts far enough to exit the hole, the stored rotational energy in the spring releases through the winding cone in Branchville. The cone rotates rapidly in Branchville, SC. The tool that was in the hole becomes a projectile in Branchville. 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 Branchville, SC. This mechanism produces the serious hand and arm injuries that occur from DIY spring replacement in Branchville.
Understanding the correct procedure for spring replacement and executing it correctly under real installation conditions are different things in Branchville. Professional technicians have performed the winding procedure under training supervision and accumulated the repetitions that produce correct automatic body positioning in Branchville, SC. Correct positioning keeps the technician's body out of the path of energy release throughout the winding sequence in Branchville. That positioning is as important as the correct tools in Branchville, SC.
Herlihy Garage Doors technicians carry professional winding bars sized for the winding cones on common residential torsion springs in Branchville, SC. They follow correct winding procedures that maintain safe positioning relative to the spring and winding cone throughout the winding sequence in Branchville. They've accumulated the training repetitions that make correct positioning automatic in Branchville, SC.
A spring that's losing tension provides less counterbalancing force than the door weight requires in Branchville, SC. Disconnecting the opener and manually lifting the door reveals a door that's noticeably heavier than it was in Branchville. This progressive increase in felt weight is the spring's tension loss accumulating cycle by cycle in Branchville, SC.
A spring that isn't fully counterbalancing the door transfers the uncounterbalanced weight to the opener motor on every opening cycle in Branchville. The motor runs at a higher load than designed in Branchville, SC. It produces more heat. It accumulates wear faster in Branchville. The door moves more slowly because the opener is doing significantly more mechanical work than designed in Branchville, SC.
A torsion spring failure produces a sharp loud bang as the stored rotational tension releases at the fracture point in Branchville, SC. The bang is often heard throughout the home in Branchville. The door either drops if in motion or stays at its current position in Branchville, SC. The opener runs but the door won't follow in Branchville. Do not run the opener after a spring snap in Branchville, SC.
A broken torsion spring separates at the fracture point and creates a visible gap in the continuous coil in Branchville. The gap is typically one to three inches wide and is visible by looking at the spring on the shaft above the door in Branchville, SC. A visible gap means complete spring failure in Branchville. The door should not be operated until the spring is replaced in Branchville, SC.
A door that's noticeably higher on one side during operation has unequal spring tension or cable tension between the two sides in Branchville, SC. On a two-spring system, a spring that has lost tension on one side produces a door that rises unevenly in Branchville. Herlihy Garage Doors assesses spring condition on both sides when uneven door travel is reported in Branchville, SC.

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