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

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