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

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