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

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