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

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