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

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