Window cleaning at height can involve fall protection, lifts, suspended or powered access, building anchors, roof rules, and public exclusion zones. Requirements depend on the chosen method and property. Ask the provider to identify its access and safety plan, then verify equipment, inspection, training, permit, and building-system claims with the responsible parties.
Coordinate security, tenant privacy, interior access, loading, emergency routes, weather stops, and property-specific standards before mobilization. The agreement should state who evaluates any building-provided access system, controls the area below, protects landscaping and finishes, and accepts incomplete or weather-delayed elevations.
Planters, terraces, water edges, parked vehicles, and tenant activity can make the assumed access path unavailable. Validate staging during the site walk and identify an approved alternate before pricing production.
Scratches, coating damage, failed seals, construction residue, and mineral etching can create disputes after cleaning. Photograph representative conditions and approve a test result before using restoration tools or treating defects as routine soil.
