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

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