Automatic Sliding Doors
Your automatic sliding entrance is the first thing a customer touches. We install and service it so it opens on cue, closes safely, and stays out of the way.
Automatic Sliding Doors in Sacramento & Northern California
An automatic sliding door is a machine, and like any machine it drifts out of adjustment. Activation sensors lose their pattern and hold the door open on an empty lobby. Belts stretch until the slide judders. Carriers wear and the panels drag on the threshold. Safety sensors get knocked out of alignment and the door starts closing on people. None of that is unusual — it just means the entrance is due for service.
Guardian Door LLC installs, repairs, replaces, and maintains automatic sliding doors for grocery and retail, medical and healthcare, office, hospitality, and municipal buildings across Sacramento and Northern California. We work on single-slide, bi-parting, and telescoping systems — operators, header assemblies, carriers and tracks, belts, panels and glass, breakout hardware, activation and presence sensors, controls, and the safety sensing that keeps the door from touching a person. Every visit ends with the entrance cycled and checked against the manufacturer's specs and ANSI/BHMA A156.10 safety requirements.
How Automatic Sliding Doors Works
What to expect from the first call through the finished opening.
- 1
Entrance assessment
We evaluate the operator, header, track and carriers, panels, sensors, and controls, and identify anything that no longer meets safe operating standards.
- 2
Scope and quote
You get written pricing that separates required safety corrections from optional upgrades, so nothing is bundled in without your say.
- 3
Install or repair
New sliding systems, operators, header assemblies, sensors, and controls are installed; existing units are repaired and rebuilt where the equipment supports it.
- 4
Sensor and timing setup
Activation patterns, presence sensing, hold-open time, and opening and closing speeds are set per the manufacturer's specifications.
- 5
Safety verification
The finished entrance is cycled and checked for safe closing, correct sensor coverage, breakout function, and ADA-compliant clear width.
