What We Do
Our Services
From emergency repairs to full installations, Guardian Garage Door Co. delivers expert service on every job.
Garage Door Repair
From broken panels and damaged tracks to misaligned doors and worn hardware, we diagnose and fix all garage door issues quickly and correctly the first time.
Door Tune-Ups
A comprehensive inspection and adjustment of all moving parts — lubrication, balance testing, safety checks — to keep your door operating smoothly and extend its lifespan.
Roller Replacement
Worn or noisy rollers cause unnecessary strain on your door system. We replace them with high-quality nylon or steel rollers for a quieter, smoother operation.
Spring Replacement
Broken torsion or extension springs are a safety hazard. Our technicians handle spring replacement with precision, restoring proper balance and tension to your door.
Cable Replacement
Frayed or snapped lift cables can cause your door to fall or operate unevenly. We replace damaged cables with durable, properly tensioned replacements for safe operation.
Opener Replacement & Installation
Whether your current opener has failed or you're upgrading to a new system, we install and configure all major brands of garage door openers with precision.
