I spent a night or two researching if this was a project we could handle ourselves. But with the age of the house and the potential for asbestos within the popcorn, I was quick to realize this was a job for the pros.
We are lucky, our real estate agent came with a stockade of "guys". "I got a 'guy' who can remove that popcorn" she says. "Oh yeah, what's his number?" And so it was.
He showed up, he brought a couple more "guys" and they knocked it out (safely mind you), smoothed it, sanded it and made an 87 year old ceiling look relatively new.
Luckily the popcorn had never been painted which allows the ceiling to absorb water and be scraped off in nice chunks, versus dust mania. This made removal safer and less costly. NEVER paint a popcorn ceiling you don't love.
Bonus, they even primed it. It's beautiful and glaringly white, making everything else look so dingy. Of course, we have many other projects to complete before we can catch up to these ceilings. At least now I can sleep.
