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

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