Garage Door Repair in San Antonio That Provides Warranty
Warranty length depends on the part, not a flat number across the board.
Springs: 3 to 12 years, based on the spring’s cycle rating and the door’s weight.
LiftMaster openers: up to 15 years, with lifetime coverage on select models.
Doors and panels we supply and install: up to 20 years.
Cables, rollers, and smaller hardware carry shorter coverage since they wear out faster
Anyone can promise a warranty. Fewer companies can explain exactly what it covers and why the length changes from one part to another. We think that explanation matters, so here’s how warranty coverage actually breaks down on a typical repair.
Springs: Warranty Tied to Cycle Life
We carry several spring types, and the warranty on each one is tied directly to its rated cycle life. A standard spring is rated for around 10,000 cycles. A high-cycle spring can reach 25,000. That range is exactly why our spring warranties run from 3 to 12 years depending on which spring goes on your door.
We also factor in the door’s weight when matching a spring. A heavier door works the spring harder on every cycle, so the warranty we offer reflects that. A lighter single-car door paired with a high-cycle spring can sit at the top end of that range. A heavy insulated double door on a standard spring will sit closer to the bottom.
Tip: Ask what cycle rating your spring carries, not just the warranty number. The two are directly connected, and a higher-cycle spring is the reason a longer warranty is possible in the first place.
Openers: Up to 15 Years on LiftMaster
For openers, we install LiftMaster almost exclusively, and warranty coverage runs up to 15 years depending on the model. A handful of specific LiftMaster models carry a lifetime motor warranty. Which warranty applies depends on which unit fits your door and your usage, so we’ll tell you exactly what coverage comes with the opener we recommend before any work starts.
Doors and Panels: Up to 20 Years
When we supply and install a new door, the panels and core materials carry warranty coverage of up to 20 years. This applies to garage door installation jobs where we provide the door itself, not repairs on an existing door from another installer.
Cables, Rollers, and Hardware: Shorter Coverage by Design
Cables, rollers, and similar hardware wear out faster than springs, openers, or panels, so they carry shorter warranty terms. That’s intentional, not a downgrade. These parts are exposed to friction and the elements every time the door runs, and cables in particular are prone to rust and fraying over years of use.
Watch for this: If a company offers a warranty of 15+ years on cables, that’s worth questioning. Cables corrode and wear with regular use. A warranty that long doesn’t match how that part actually behaves. Focus your attention on the warranty for the major components: the opener, the springs, and the door itself. Those are the parts that matter most and the ones worth confirming in writing before any repair.
