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

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