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

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