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

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