Compare replacement of worn moving parts or controls with a new entrance when equipment is obsolete or no longer suits the opening. Compatibility and safety verification matter as much as initial price. The complete breakdown is in our automatic sliding doors guide.
Replacement decisions should consider overall condition, obsolete parts, repeated failures, and whether the existing equipment fits current demand. Compare a component replacement with a complete system, and identify which retained parts will be checked for compatibility.

We evaluate the operator, header, track and carriers, panels, sensors, and controls, and identify anything that no longer meets safe operating standards.
You get written pricing that separates required safety corrections from optional upgrades, so nothing is bundled in without your say.
New sliding systems, operators, header assemblies, sensors, and controls are installed; existing units are repaired and rebuilt where the equipment supports it.
Activation patterns, presence sensing, hold-open time, and opening and closing speeds are set per the manufacturer's specifications.
The finished entrance is cycled and checked for safe closing, correct sensor coverage, breakout function, and ADA-compliant clear width.
Not necessarily. A sound assembly may only need compatible components. Widespread damage, unavailable parts, or unsuitable capacity can justify replacement; the assessment and written scope should explain the recommendation.
