Automatic Sliding Door Installation
Automatic door installation is a system, not a door: operator, carriages, belt, controller, activation sensors, safety sensors, and locking all have to be specified together and set up against each other. We survey the opening, size the operator to the panel weight and traffic volume, and install with the safety sensing configured before the door is ever handed over.
We install single-slide, bi-parting, and telescopic sliding systems in new openings and as retrofits into existing storefronts.
Commercial Automatic Sliding Doors
Commercial entrances see thousands of cycles a week, and the difference between a five-year door and a fifteen-year door is almost always the operator specification. We size the system for real traffic, not the minimum that fits the opening.
Automatic Sliding Door Repair
Automatic door repair covers everything from a sensor that’s drifted out of alignment to a failed motor or drive belt. Because the symptoms overlap — a door that won’t open could be sensor, controller, motor, or a binding panel — diagnosis is the job, and guessing at parts wastes your money.
Our technicians repair motors, gearboxes, drive belts, carriages and rollers, controllers and logic boards, activation and safety sensors, wiring faults, locks, and bottom guides and tracks.
Automatic Door Maintenance & Safety Checks
Automatic doors are one of the few pieces of building equipment that touch every visitor, and the safety sensing that prevents them touching too hard needs verifying on a schedule — not after an incident.
A maintenance visit covers belt tension and wear, carriage and roller condition, track and guide cleaning, sensor pattern and alignment, opening force, speed and hold-open timing, breakout function, and a full safety check against ANSI/BHMA A156.10.
Scheduled Automatic Door Service
Planned automatic door service costs less than emergency call-outs and far less than an entrance out of action on a trading day. We set up recurring visits for single sites and multi-site estates, with a documented report after each one.
Signs Your Automatic Door Needs Service
- The door opens late, closes early, or hesitates mid-travel
- It opens with nobody there, or fails to detect someone approaching
- Grinding, squealing, or knocking from the header
- The panels judder, bind, or drag on the bottom guide
- The door reverses for no reason, or closes harder than it used to
- The hold-open time has drifted noticeably longer or shorter
How We Work
- Call and describe the fault. Timing faults and mechanical faults point to different parts of the system.
- Site survey and diagnosis. We test the operator, sensors, and controller as a system rather than swapping parts speculatively.
- Install, repair, or service. Common operator and sensor parts are carried on the van.
- Programme, test, and document. Speed, force, and hold-open set correctly, safety verified, and a written record for your files.

Frequently Asked Questions
How often should automatic doors be serviced?
Industry practice is a documented safety check at least annually, and semi-annual or quarterly service on high-traffic entrances. Doors in retail and healthcare typically need the shorter interval.
Why does my automatic door open when nobody is there?
Usually a motion sensor picking up traffic, foliage, or reflective movement outside its intended pattern — occasionally a fault in the sensor itself. Re-aiming or re-masking the sensor normally solves it.
Can you repair any make of automatic operator?
We work on all the major operator brands, including systems no longer supported by the original supplier, and can advise when a retrofit operator is a better investment than another repair.
Do you offer maintenance contracts across multiple sites?
Yes. We schedule recurring visits across multiple locations and provide a consistent report format for each door so facilities teams can track them centrally.
