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

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