Professional automatic sliding door installation is what turns a powered door into a safe, reliable entrance. This 2026 guide explains what automatic sliding door installation involves and how the process works for homes and businesses in Johannesburg, Pretoria, Gauteng, Cape Town and Durban – so you know exactly what to expect before the team arrives on site.
What automatic sliding door installation involves
An automatic sliding door glides on a track driven by an overhead operator, so the fitting focuses on a level track, a true opening and precise sensor alignment. A proper job covers fitting the operator, setting up the sensors, wiring the power and testing every safety function before handover. The installer also sets the opening speed, hold-open time and safety zones so the door is comfortable and compliant from the first day.
Preparing for the installation
A sliding door needs clear wall space for the panels to travel and a sound lintel to carry the track. Getting the power supply and the opening ready in advance keeps the job quick and avoids a return visit. For a retrofit, the team assesses the existing structure and makes good where needed; for a new build, the opening is planned in from the start so everything lines up.
The automatic sliding door installation process, step by step
- Survey the opening and confirm the track length and panel travel.
- Mount the header beam and overhead operator.
- Hang the sliding panels and set the track and rollers.
- Fit and align the motion and safety sensors.
- Wire the power, add battery backup, and commission.
- Test opening speed, hold-open time and safety zones, then hand over.
Following these steps, a straightforward automatic sliding door installation is usually completed within a day, though bi-parting or access-controlled doors take longer to commission. The result is a smooth, quiet entrance sized to your traffic.
Single versus bi-parting sliding doors
A single-leaf sliding door suits a shopfront or side entrance, while a bi-parting two-leaf door handles the highest foot traffic in malls, clinics and airports. Bi-parting units take a little longer to commission because both leaves and their sensors must be balanced.

Explore the automatic doors range, see our automatic door installation service and installation cost guide, and tell us your opening details. Every door we fit is set up to the EN 16005 safety principles for powered pedestrian doors.
Tips for a smooth installation
Plan the electrical supply early, confirm the opening size and finished floor level, and keep the area clear for the team on the day. Ask about warranty on the operator, whether servicing is included for the first year, and how quickly call-outs are answered – a public entrance that fails is a serious disruption to any business. Choosing quality hardware and proper commissioning up front keeps both the fitting and the running cost predictable, and it means the door opens smoothly and closes safely for years.
