Extension Spring Replacement in Kansas City, KS
Extension springs run along the horizontal tracks on each side of the door and stretch under tension to lift the door's weight. When one breaks, the door either won't move or hangs crooked and strains the opener. Most Kansas City homes built before 1990 use this spring type, and they wear out after roughly 10,000 cycles.

When to Call
When You Need Extension Spring Replacement
- You heard a loud bang from the garage and the door won't open
- The door opens a few inches then stops or feels extremely heavy
- One side of the door sags lower than the other when moving
- You can see a gap or separation in the spring coil itself
- Your opener motor runs but the door barely lifts off the ground
- The safety cable threaded through your spring is frayed or snapped
How It Works
Our Process for Extension Spring Replacement
- 1
Phone Assessment
We ask a few questions about what you heard and what the door is doing. That tells us what parts to bring before we arrive.
- 2
Safe Disconnect
We disconnect the opener and manually secure the door so it cannot drop during the work. Extension springs hold real tension even when broken.
- 3
Full Spring Inspection
We check both springs, the pulleys, the cables, and the cable drums. One broken spring usually means the other is close behind.
- 4
Paired Replacement
We replace both springs at the same time, even if only one broke. Mismatched wear causes uneven lift and shortens the new spring's life.
- 5
Tension and Balance Test
We set correct tension, then let go of the door at mid-height. A balanced door stays put. We adjust until it does.
- 6
Reconnect and Cycle
We reconnect the opener and run the door through several full cycles, checking that the auto-reverse and force settings are still calibrated correctly.
What's included
- Both extension springs replaced as a matched pair, same weight rating
- Inspection of pulleys, safety cables, and cable drums for wear
- Tension adjustment and door balance verification before we leave
- Opener reconnect and basic force-setting check included in the visit
- Removal and disposal of the old springs
What's not included
- Cable or pulley replacement if those parts are also damaged — that's priced separately
- Opener repairs if the motor or logic board was damaged when the spring broke
- Conversion from extension springs to torsion spring system — that's a different job entirely
Real Situations
Common Scenarios in Kansas City
A homeowner in Rosedale comes home to find her car trapped inside after a spring snapped during the morning commute.
We walk her through the manual release so she can get the car out before we arrive. When we get there, we replace both springs and check the cables, which had visible fraying on one side.
A landlord in Kansas City, KS calls about a tenant's door that moves but sounds wrong and shakes on one side.
We find one spring still intact but stretched beyond useful tension. We replace the pair, re-route a cable that had slipped its pulley, and confirm the door moves smoothly before closing the call.
A homeowner doing a weekend inspection notices the safety cable on one spring is completely missing.
Missing safety cables are a real hazard — a snapping spring without one can travel fast. We install new cables on both sides and replace the springs since they were original to a mid-1980s door.
Kansas City Context
Why this matters in Kansas City
A large share of Kansas City, KS housing stock dates from the 1950s through the 1980s, and most of those garages were built with extension spring systems. The freeze-thaw cycles here put extra stress on springs each winter, especially on north-facing doors that stay cold longer. Springs on older homes in areas like Armourdale or Strawberry Hill are often original and well past their rated cycle life.
Straight Talk
About pricing & scope
Price depends on the door's weight rating, which determines the spring size we need. Heavier two-car doors require heavier springs. If we find damaged cables or pulleys during inspection, we'll show you and explain the added cost before touching anything extra. We don't swap parts without telling you first.
