My experience after managing a down to the studs house remodel last year, is that if you watch a lot of YouTube videos to determine the best techniques and you are a bit of a perfectionist, you have a 90% chance you will do a better job than the “pros”.
Fyi, the 2 trades I fired half way through the project were the plumber and the tile setter. Both were from referrals and licensed. I wanted to leave bad reviews online, but didn’t trust them as they know where I live.
