The demolition garbage container, penalty clause for missing deadline, NO demolition until everything is ordered and delivered (otherwise they demolish your bathroom and don’t come back for three weeks).
Hanging the medicine cabinets
Electric outlets and switches
Lighting
painting
windows & doors
Lead pan under shower and tub
heating/ a/c
Basically everything
And BTW pay for all the raw materials yourself so they can’t put a lien on your house if your contractor doesn’t pay the store. Pay all the subs yourself as well. Make copies of all the checks you pay out and keep clear and concise records. Write everything down including names, times and phone numbers.
Never get ahead of yourself. Make a payment schedule. Pay “x” amount after demolition. “X” after laying tiles. etc. If they didn’t lay the tiles don’t give them the money you were supposed to give them for laying the tiles. If they didn’t install the fixtures don’t give them the money until they are in and work well. Don’t finish paying them until everything is completed to your satisfaction.
