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

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