I agree, huge mess and pain in the ass to scrap off.Fuck popcorn ceilings. I redid my whole basement. Ceilings, ceiling lighting, flooring, brickwork around the fireplace, even put in a wine cellar.
And I still think about what a godawful mess the popcorn ceiling removal was, everything else was a pleasure.
$2k for all that seems not unreasonable.
I was tempted just to drywall over it.
