Garage door spring replacement in San Dimas, CA

Broken or worn springs make your door unsafe and unreliable. Discount Garage Door Repair Service replaces torsion and extension springs for homes and businesses across San Dimas with same‑day availability and experienced technicians.

Garage door springs are the primary counterbalance for your door. When a torsion or extension spring fails, the door can become heavy, unbalanced, or stuck — creating a safety hazard and risking damage to the opener and other components. Our technicians diagnose the spring type, measure wire size and wind, and replace springs with parts sized to restore correct balance and safe operation.

We service residential and commercial doors across San Dimas neighborhoods including Historic Downtown San Dimas, Lone Hill, Bonita, and San Dimas Canyon, and near landmarks such as Frank G. Bonelli Regional Park (Puddingstone Reservoir) and Raging Waters. Led by Michael D. Hendricks, our team performs full spring replacement, inspects cables, drums, and brackets, and tests door balance and opener operation before leaving your property.

Technicians carry common springs and parts to complete most replacements on the first visit. We work on standard sectional doors, roll‑up units and light commercial doors. If additional work is required — like cable replacement or track repair — we provide a clear estimate and explain options so you can choose the most cost‑effective repair.

How It Works

1

Step 1 — Schedule and assessment

Call (626) 931-9442 or email dgdrs15@gmail.com to describe the issue. We operate seven days a week, 8:00 AM – 8:00 PM, and can usually arrange same‑day diagnostics. A technician arrives, inspects the door, determines spring type and damage, and explains the recommended replacement.

Step 2 — Replacement and safety check

We remove the failed spring and install a correctly sized replacement using proper winding bars and safety procedures. The technician adjusts tension, checks cable alignment, inspects drums and rollers, and tests door balance and opener interaction to ensure the door operates safely and smoothly.

Step 3 — Review and follow‑up

Before we leave, we demonstrate the door operation and review any additional repairs that could extend service life. You receive clear care advice and a written invoice. If follow‑up is needed, we schedule return service or provide maintenance recommendations to prevent future failures.

Pricing varies by spring type (torsion vs. extension), door weight and size, and whether additional components (cables, drums, bearings) need replacement. Because these factors change the scope of work, we provide on‑site estimates before starting repairs. Call (626) 931-9442 to request a written quote or ask about same‑day availability.
