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

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