What Goes Wrong With Automatic Sliding Doors?
Sliders fail in predictable ways. The header was not level, so panels drift and the motor works harder every cycle. The track sits in a slush puddle all winter and ices up. Sensors were aimed for a summer foot pattern, so the door opens every time someone walks past on the sidewalk and the vestibule never warms up. Breakout panels were painted shut or blocked by a display, so the entrance is no longer a legal exit.
Most of these trace back to an install that treated the slider as an appliance rather than an entrance. The header, threshold, glazing and egress all have to work together.
What Is Included in Automatic Sliding Door Installation?
A complete automatic sliding entrance: header with operator and track, sliding panels, sidelites, breakout hardware, sensors, threshold and the commissioning that makes it safe. As a commercial door contractor serving Toronto and the GTA, we install new entrances and replace tired sliders with current packages.
The written CAD spec lists:
- Package make and model: Record, Besam or Horton
- Configuration: single-slide or bi-parting, panel and sidelite sizes
- Breakout: full breakout or sliding-panel breakout per egress requirements
- Glass: tempered or laminated safety glass to CAN/CGSB-12.1
- Sensors: BEA or Optex motion and presence zones per ANSI/BHMA A156.10
- Threshold: standard, low-profile or heated for winter
- Power, night lock and access control tie-ins

Types of Automatic Sliding Doors We Install
Bi-parting sliders
Two panels opening from the centre for the widest clear opening. The default for grocery, hospital and big-box entrances.
Single-slide units
One panel sliding past a fixed sidelite. Good for narrower openings and entrances with a wall on one side.
Vestibule pairs
Inner and outer sliders sequenced so both are never fully open at once, which matters every January.
Telescopic sliders
Multiple panels per side for a wide clear opening in a tight wall. Used where gurneys, carts or pallets pass through.
How Much Does an Automatic Sliding Door Cost in Toronto?
| Scope | Typical range | Main cost drivers |
|---|---|---|
| Single-slide replacement in existing opening | $4,500-$7,000 | Panel size, glass, sensors |
| Bi-parting with breakout sidelites | $7,500-$11,000 | Width, finish, threshold |
| Bi-parting with header steel and heated threshold | $10,000-$12,000 | Structural prep, heat trace |
Glazing upgrades, dark bronze or custom finishes and access control integration add to the base. The spec shows each line.
When Do You Need an Automatic Slider?
- Constant foot traffic where swing doors cause bottlenecks
- Carts, strollers, wheelchairs and deliveries passing all day
- An old slider with frequent service calls or unavailable parts
- A storefront rebuild that is changing the entrance anyway
- Accessibility goals that a swing operator cannot meet in the space
Slider vs Swing Operator
A swing operator is cheaper and fits the existing door and frame. A slider moves more people, needs less interaction and has no swinging leaf to clear, but it needs wall space and a new header. For an existing entrance with modest traffic, start with our automatic door operator installation. For grocery, medical and high-volume retail, a slider is usually the right call.
Codes and Standards
We install to ANSI/BHMA A156.10 for power-operated pedestrian doors, use CAN/CGSB-12.1 safety glazing, and keep breakout egress functional per OBC exit requirements. Barrier-free considerations follow the AODA Design of Public Spaces standards.
