Garage Door Cable Replacement in Denver, CO

Garage door lift cables work in tandem with your springs to raise and lower the door smoothly and evenly. When a cable snaps or frays, the door can drop suddenly, hang at a dangerous angle, or become completely stuck. In Denver, CO, our technicians replace both standard lift cables and safety cables on all residential door configurations. Cable failure is often related to spring wear — when a spring breaks, the sudden load can snap a cable simultaneously — so we always inspect both systems together. We use galvanized steel cables rated for your door's specific weight and travel distance. Every cable job includes a drum and bottom bracket inspection to ensure the entire lifting system is working as a unit before we close out the appointment.

Our Garage Door Cable Replacement Process

Every job follows the same structured approach — no shortcuts.

1. 1

   Safety Assessment

   We clamp the door in place and relieve spring tension before touching any cables, ensuring the door can't drop unexpectedly during the repair.

2. 2

   Old Cable Removal

   We remove the damaged cable from the bottom bracket and drum, inspecting both components for wear, corrosion, or damage caused by the cable failure.

3. 3

   Cable Sizing & Replacement

   We install a correctly sized galvanized cable — matched to your door's height and weight — and route it through the drum with the proper number of wraps.

4. 4

   Tension & Drum Alignment

   We re-tension the spring system and align both drums so the cable wraps evenly on both sides, preventing future uneven wear.

5. 5

   Full System Test

   We cycle the door multiple times, checking for even travel, smooth operation, and proper seating of the cable in the drum groove on both sides.

Frequently Asked Questions

What causes garage door cables to break in Denver?

The most common causes are age-related metal fatigue, a broken spring that places sudden full load on the cable, and corrosion from moisture — which is worth monitoring in Denver's varied seasonal conditions.

Can I use my garage door with a broken cable?

No. A door with a broken cable is structurally unbalanced and can drop suddenly, damage the track, or injure anyone nearby. Keep the door in the closed position and call for service immediately.

Do you replace both cables at the same time?

We always recommend replacing both cables together. They were installed at the same time and have equal wear. Replacing only the broken one typically results in the second failing within weeks.

How long does a cable replacement take?

Cable replacement typically takes 45 minutes to 90 minutes depending on whether we also need to address a related spring failure. We carry parts on our trucks for same-day completion.
