Start with the existing finish
Height, access and furniture protection form part of the estimate.
Painted texture changes the decision
The surface is tested for paint and adhesion so removal does not create unnecessary substrate damage.

Repairing the exposed ceiling
When joint and patch variation continues across the ceiling, broader skim coating may be considered before sanding and primer.
The finishing scope may include ceiling repair, skim coating, sanding, primer and paint. Not every ceiling needs every stage.
Multi-room finishing
Open connected spaces are sequenced around compound drying and sanding. Painted texture can expand the complete service scope.
What affects the estimate?
Area is one factor, but it does not describe the whole job. Height, access, number of rooms, furniture protection, coating, substrate damage and the finish required all contribute to the scope.
