What to establish before the ceiling is disturbed
Gather the survey, a room plan and photographs taken without disturbing the surface. Mark new lighting, ventilation and other penetrations as well as the visible finish changes. Ask whether fixtures need isolating or removing by another trade, how the room will be released for finishing, and what closeout records will be provided. Do not scrape a test patch or sand the coating to see how easily it comes away.
Survey and project requirements in Washington
Puget Sound Clean Air Agency publishes separate guidance for renovation and demolition. Have the assessor and contractor confirm the survey scope, applicable notifications and disposal arrangements for the actual property and work. A building permit does not replace the asbestos assessment.
