re: Pricing for Sheetrock (Ceiling) Repair?

Might want to go ahead and prepare yourself to paint the whole ceiling in the den. That's likely going to be a noticeable paint touch up and the Mrs. Isn't going to stand for that in the den. I suspect your price is going to climb once the work commences.
Maybe you'll get lucky and the guy doesn't know the value of his skill or time (providing he does a quality job)
