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

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