@Edwin E. I had walked through the project with the contractor before we started work. I outlined exactly what was to happen including using painters tape to denote what was to be gutted. To help the whole project along, I figured it would be best to leave each room's scope of work taped to the walls for the contractor to execute on. I did not have a signed agreement w/ the contractor (lesson learned), however the lack of contract cut both ways, see below.
The bathroom's SOW was to only remove the lower 4' of drywall because of damage to the drywall. The first infraction from the contractor was that he removed all 8' of drywall. I informed the contractor that he did too much and needed to follow my direction, rather than direct the project himself. He gave a bunch of excuses, but relented and said he would follow directions.
After I posted this issue is when J. Scott advised I fire the guy.
I gave the contractor the next milestones to accomplish (gutting the basement), this was a Sunday night directive for execution on Monday. Monday, received a phone call from the contractor asking about removing the bathroom's plumbing. I said no, focus on the basement.
Phone call on Tuesday morning from the contractor. Question about demolition in the basement (which should have happened on Monday). Contractor mentioned that the bathroom is now a blank slate. I said "You're kidding". Reply: "No, I figured it'd be easier for you later. I pulled all the plumbing."
I informed the contractor I wanted all of his time/bills and to not return to the site until I had a new plan forward. I made my decision to fire the guy on Wed/Thurs and received the invoices on Friday. The guy included mileage to and from his house even though he never worked more than 7hrs/day (I could maybe see discussing mileage if he was working 4x10s). He had the audacity to include time for the 'full demolition of the bathroom' and to bill me for materials to make the repairs for what he demolished.
I said the contract cut both ways. I didn't pay his mileage (if he didn't drive, he didn't have a job), I didn't pay for his time to demolish the bathroom, didn't pay for the repair materials and didn't pay his estimated costs to bring the space back to 'pre demolition' state. I explained that those costs were his to bear because he decided, against my direct instructions, to conduct this work.
I'm glad I was quick to heed J. Scott's advice the 2nd time although I've lost one week's time, money for new drywall, studs, waste plumbing and a subfloor.
After I fired him, I learned that the basement, which had three rooms when he started, and was to have three rooms when he finished, finished up with only two rooms as he thought it would be better to only have two rooms. Hind sight is 20/20, I shouldn't have paid him until a full review of the site (I was so shocked at the bathroom, I stopped there). I should have also gotten a quote from another contractor and deducted that amount from the final invoice because that is what I will have to pay.
Overall, my new contractor is going to execute more work than the first contractor at a price approximately 20% less than the first contractor. (It's written in a signed contract)
