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

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