We completed a 6 month renovation of our home in January. So I have just gone through that experience and that causes me a few comments:
1. How will you protect yourself from workers perhaps being contagious? How will you protect workers from you perhaps being contagious? Virus can be passed by asymptomatic people. Lots of people aren't allowing anyone in their house at all, let alone workers who will be there on multiple occasions. Are you really going to allow workers in your house working close to one another and touching your home surfaces, etc.?
2. What happens if you get Covid while the work is going on? Work will have to stop at a minimum for the time you are quarantined. And, that assumes the workers would be willing to come back after you recovered (which may not be a good assumption).
3. What if your local or state government shuts down non-essential business? This is the type of work that could end up being shut down. It is very, very, very difficult to go through remodeling. I can't even imagine what it would have been like to, say, have my master bathroom gutted with a huge hole in the ceiling and the floor and then had the work stop abruptly for what might be months. If you want to take that risk...just make sure you understand that risk exists.
