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

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