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

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