Contractors are creatures of habit, and most have bad contracts, so without knowing which contractors they choose I could say if it was Company XYZ look at the assumption the existing walls don’t require any prep & their hourly rate for remediation. Company ABC omits prices for drywall work, so even touch ups require you to hire a separate company. Company 123 won’t give you a timeline, because they aren’t known for being dependable. Company 789 does good work and they are big enough to get it done quicker than anyone, but we’re usually 80% as fast, 2/3rds the price, higher quality and we don’t lock you in to the paint they spec out. Company JamakaMePaint uses as little paint as they can - ask to look at any of their previous jobs and you’ll see pin holes on textured walls. Company DontAskDontTell, well, I would clarify with them that no convicted felons will be working inside your house. “Even though we are booked solid 6 months out I can start prepping trim and caulking this afternoon, and we can squeeze in one day of work each week until it’s done if you would like to get started, or you can wait and we’ll do it all at once starting on July 7th.“ That’s usually an easy close.
