The opener strains audibly and the door moves more slowly than it should in Highland Acres — the spring isn't providing its full counterbalancing force and the opener is compensating with every cycle in Highland Acres, DE. Or a spring snapped — you heard the bang and the door won't move in Highland Acres. Call Herlihy Garage Doors now for same-day spring repair throughout Highland Acres, DE in Highland Acres. Do not run the opener and do not attempt to manually lift the door after a spring snap in Highland Acres, DE.
Garage door spring work is the most safety-critical service in the garage door industry for a specific reason in Highland Acres. A residential torsion spring stores several hundred foot-pounds of rotational energy when wound to operating tension in Highland Acres, DE. That energy is released in a controlled way when the door opens through the spring's correct unwinding in Highland Acres. It releases in an uncontrolled way when a tool slips from the winding cone during spring replacement in Highland Acres, DE. The winding cone has four holes designed for professional winding bars of a specific diameter in Highland Acres. A winding bar that fits these holes correctly maintains contact throughout the winding process in Highland Acres, DE. 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 Highland Acres. When it slips, the stored energy releases instantly and the cone rotates at high speed in Highland Acres, DE. The improvised tool becomes a projectile in Highland Acres. This is not a theoretical risk in Highland Acres, DE. It's the mechanism behind the serious injuries that occur from DIY spring replacement every year in Highland Acres.
Herlihy Garage Doors repairs and replaces garage door springs throughout Highland Acres, DE in Highland Acres. The correct specification is measured from the specific door configuration before any spring is selected in Highland Acres, DE. The replacement spring is wound to the correct turn count for the specific door height and cable drum in Highland Acres. The balance test confirms the specification is correct before the opener is reconnected in Highland Acres, DE. Same-day service available throughout Highland Acres in most cases in Highland Acres, DE. And every spring repair is guaranteed in Highland Acres.
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 Highland Acres. An oversprung door can behave dangerously under manual operation in Highland Acres, DE. An undersprung door adds abnormal load to the opener motor, drive gear, and cables on every cycle in Highland Acres. Neither produces the correctly balanced door that every other component in the system depends on in Highland Acres, DE. Herlihy Garage Doors measures the correct specification before any spring is selected in Highland Acres.
The spring specification determines the door's balance in Highland Acres, DE. The door's balance determines the load the opener, cables, and rollers operate under in Highland Acres. Every component in the door system performs correctly when the spring is correctly specified and performs under abnormal load when it isn't in Highland Acres, DE. The spring specification is the foundation variable from which everything else in the system's performance follows in Highland Acres.
A torsion spring is mounted on a steel shaft directly above the garage door opening in Highland Acres, DE. When the door closes, the cables pull down on the cable drums, rotating the shaft and winding the spring tighter in Highland Acres. The winding stores rotational energy in the spring coil in Highland Acres, DE. 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 Highland Acres. 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 Highland Acres, DE. This counterbalancing force is what makes a 200-pound garage door movable with 10 to 20 pounds of net force from the opener in Highland Acres.
Extension springs run horizontally along the upper track sections on each side of the door in Highland Acres. They store energy by stretching rather than rotating in Highland Acres, DE. When the door closes, the springs extend and store energy in their stretched length in Highland Acres. 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 Highland Acres, DE. 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 Highland Acres. Herlihy Garage Doors inspects and installs safety cables on every extension spring service in Highland Acres, DE.
Wire diameter determines how much energy the spring stores per turn in Highland Acres, DE. A heavier wire diameter stores more energy per turn than a lighter one in Highland Acres. Inside diameter determines which shaft size the spring fits on in Highland Acres, DE. Length determines the total number of active coils and therefore the total energy storage capacity in Highland Acres. 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 Highland Acres, DE.
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 Highland Acres. Winding it to the correct turn count produces insufficient lifting force in Highland Acres, DE. The door is undersprung in Highland Acres. A spring with the correct wire diameter and inside diameter but a length that's too short has fewer active coils in Highland Acres, DE. Each coil must be wound tighter than designed to produce the required energy storage in Highland Acres. The spring is more likely to fail before its rated cycle life in Highland Acres, DE.
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 Highland Acres, DE. Door height and cable drum size determine the correct winding turn count in Highland Acres. Door weight estimated from size, steel gauge, insulation type, and window configuration determines the correct wire diameter and length in Highland Acres, DE. The specification is calculated, not estimated in Highland Acres.
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 Highland Acres, DE. Three hundred foot-pounds is the equivalent of a 150-pound weight dropping two feet in Highland Acres. That energy is stored in the spring coil as rotational tension on a steel shaft in Highland Acres, DE. When released correctly during spring replacement, it simply unwinds the spring back to the neutral state in Highland Acres. When it releases suddenly during a tool slip, it releases all at once through the winding cone in Highland Acres, DE.
The winding cone has four holes sized for professional winding bars of a specific diameter in Highland Acres. Professional winding bars are 18 to 24 inches long and the correct diameter to fill the winding cone holes with minimal play in Highland Acres, DE. The length provides leverage and clearance in Highland Acres. The correct diameter fit prevents the bar from shifting in the hole during winding in Highland Acres, DE. Any movement of the bar in the hole during winding is a slip hazard in Highland Acres.
An improvised tool that's too narrow to fill the winding cone hole can shift in the hole during winding in Highland Acres, DE. When it shifts far enough to exit the hole, the stored rotational energy in the spring releases through the winding cone in Highland Acres. The cone rotates rapidly in Highland Acres, DE. The tool that was in the hole becomes a projectile in Highland Acres. 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 Highland Acres, DE. This mechanism produces the serious hand and arm injuries that occur from DIY spring replacement in Highland Acres.
Understanding the correct procedure for spring replacement and executing it correctly under real installation conditions are different things in Highland Acres. Professional technicians have performed the winding procedure under training supervision and accumulated the repetitions that produce correct automatic body positioning in Highland Acres, DE. Correct positioning keeps the technician's body out of the path of energy release throughout the winding sequence in Highland Acres. That positioning is as important as the correct tools in Highland Acres, DE.
Herlihy Garage Doors technicians carry professional winding bars sized for the winding cones on common residential torsion springs in Highland Acres, DE. They follow correct winding procedures that maintain safe positioning relative to the spring and winding cone throughout the winding sequence in Highland Acres. They've accumulated the training repetitions that make correct positioning automatic in Highland Acres, DE.
A spring that's losing tension provides less counterbalancing force than the door weight requires in Highland Acres, DE. Disconnecting the opener and manually lifting the door reveals a door that's noticeably heavier than it was in Highland Acres. This progressive increase in felt weight is the spring's tension loss accumulating cycle by cycle in Highland Acres, DE.
A spring that isn't fully counterbalancing the door transfers the uncounterbalanced weight to the opener motor on every opening cycle in Highland Acres. The motor runs at a higher load than designed in Highland Acres, DE. It produces more heat. It accumulates wear faster in Highland Acres. The door moves more slowly because the opener is doing significantly more mechanical work than designed in Highland Acres, DE.
A torsion spring failure produces a sharp loud bang as the stored rotational tension releases at the fracture point in Highland Acres, DE. The bang is often heard throughout the home in Highland Acres. The door either drops if in motion or stays at its current position in Highland Acres, DE. The opener runs but the door won't follow in Highland Acres. Do not run the opener after a spring snap in Highland Acres, DE.
A broken torsion spring separates at the fracture point and creates a visible gap in the continuous coil in Highland Acres. The gap is typically one to three inches wide and is visible by looking at the spring on the shaft above the door in Highland Acres, DE. A visible gap means complete spring failure in Highland Acres. The door should not be operated until the spring is replaced in Highland Acres, DE.
A door that's noticeably higher on one side during operation has unequal spring tension or cable tension between the two sides in Highland Acres, DE. On a two-spring system, a spring that has lost tension on one side produces a door that rises unevenly in Highland Acres. Herlihy Garage Doors assesses spring condition on both sides when uneven door travel is reported in Highland Acres, DE.

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