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

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