Agree the remaining floor condition
Ask the abatement contractor and flooring installer to agree what the handover means. A cleared work area is not automatically a flat, dry or warranted substrate for the chosen floor covering. Keep asbestos removal, subfloor repairs, leveling and moisture assessment as explicit responsibilities. Do not grind, sand or mechanically prepare suspect adhesive before it has been assessed.
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.
