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

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