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

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