Photograph the condition before work
Capture representative elevations, staining, glass or coating concerns, access constraints, nearby drains, and any pre-existing condition that could affect the scope or expected finish.
Photograph the completed zones
Use consistent viewpoints and identify the elevation or service zone so a future reviewer can compare the result without guessing what was cleaned.
Record exceptions and next steps
Photos should be paired with notes about weather, access, areas deferred, contact-cleaning needs, remaining stains, and the next recommended visit or referral.
