Is $15,000 to remove painted popcorn ceiling and refinish a fair price?

This quote is for the removal of painted popcorn ceiling, followed by refinishing and painting the entire house ceiling. The popcorn ceiling has been painted over, making it difficult to remove with a drywall sander. A stomp texture finish is planned to hide imperfections after the ceiling has been refinished with mud. The work also accounts for existing crown molding throughout the house, which extends to the ceiling. - Scope: Remove painted popcorn ceiling, refinish, and paint - Area: Entire house ceiling - Ceiling Size: 2400 sqft - Removal Method: Scraping (drywall sander not effective due to paint) - Finish: Stomp texture - Special Consideration: Existing crown molding everywhere, extending to the ceiling
