I have a job coming up I was hoping to get some input on. A friend of mine owns a floor refinishing company and they redid a concrete floor in a basement that was flooded. They removed all of the base board but none of the casing. What they are wanting me to do is use my Fein to cut all of the casing up 6 inches, install a plinth block and install new 5 1/4 base board. There is about 120 linear feet and there are 7 doorways. I have no clue where to even begin figuring out a price for this since it is going to require quite a bit more work then normal and it's being stained and not painted which means everything has to be done a lot more finicky and fit together a lot better. Any suggestions on what would be a good bid for something like this. I hate to just try and guess on my time because I could easily see it being double or triple what I thought it would be once I get into it.
