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

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