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

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