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

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