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

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