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

Both springs were installed at the same time and have completed the same number of cycles in Loudoun Valley Estates, VA. Metal fatigue accumulates proportionally to cycles under stress in Loudoun Valley Estates. The spring that broke reached its individual fatigue threshold first due to microscopic wire structure differences in Loudoun Valley Estates, VA. The surviving spring is at essentially the same point in its fatigue progression in Loudoun Valley Estates.
Replacing both springs during today's visit costs approximately $50 to $150 more than replacing only the broken spring in Loudoun Valley Estates, 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 Loudoun Valley Estates. The total of two separate repairs consistently exceeds the cost of replacing both during the original visit in Loudoun Valley Estates, 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 Loudoun Valley Estates. Herlihy assesses the surviving spring's age and specification and advises on the correct approach for the specific situation in Loudoun Valley Estates, VA. Herlihy Garage Doors recommends replacing both springs when both are at the same fatigue progression in Loudoun Valley Estates. The specific reasoning is explained clearly in Loudoun Valley Estates, VA. The homeowner makes the final decision with complete information in Loudoun Valley Estates.
