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

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