Garage Door Spring Replacement in Denver, CO

A broken garage door spring is the single most common reason a door stops working — and it's one of the most dangerous repairs to attempt without proper training. Springs are wound under extreme tension; an improperly handled spring can cause serious injury. In Denver, CO, our technicians are trained and equipped to replace both torsion springs (mounted above the door) and extension springs (running along the sides) safely and efficiently. We stock springs sized for residential single, double, and carriage-style doors. Every replacement includes a tension calibration so the door opens and closes with the correct counterbalance, reducing strain on your opener motor. We also inspect cables, drums, and bottom brackets during every spring job — components that wear together and often need attention at the same time.

Our Garage Door Spring Replacement Process

Every job follows the same structured approach — no shortcuts.

1. 1

   Inspection & Spring Sizing

   We measure wire diameter, inside diameter, and length to identify the exact spring specification your door requires for proper counterbalance.

2. 2

   Safe Spring Removal

   Using winding bars and tension-release tools, we safely unwind and remove the broken spring without releasing stored energy suddenly.

3. 3

   New Spring Installation

   We install a matched spring — or a pair, since replacing both at the same time prevents the second from failing shortly after — and wind it to the correct tension.

4. 4

   Cable & Hardware Inspection

   We inspect lift cables, drums, and bottom brackets for wear and replace any components that show fraying, corrosion, or cracking.

5. 5

   Balance Test & Opener Adjustment

   We disconnect the opener and manually test door balance at the midpoint. A properly balanced door stays put at waist height without assistance.

Frequently Asked Questions

How much does garage door spring replacement cost in Denver?

Torsion spring replacement typically runs between $150 and $350 depending on spring size and whether you replace one or both. We provide an exact quote before starting any work.

Should I replace both springs even if only one broke?

Yes, in almost every case. Both springs were installed at the same time and have the same wear. Replacing only the broken one usually means the second fails within weeks or months.

Can I open my door manually while the spring is broken?

You can, but it requires two people and significant effort because the full weight of the door — often 150 to 300 lbs — is unsupported. Avoid using the opener; doing so can burn out the motor.

How long do new garage door springs last in Denver's climate?

Standard springs are rated for 10,000 cycles. High-cycle springs rated to 25,000 or 50,000 cycles are available for an upgrade and are a smart investment for frequently used doors.
