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

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