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

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