I got a call over the weekend. A maintenance customer had asked me for a bid earlier for flagstone work and I didn't get back to him him soon enough. I'm scrambling right now to throw some numbers together. I called a local supplier and they gave me a number of a guy who does stone. The bid is for overlay on a patio and concrete walkway plus a good sized 3ft pathway. The guy I called told me 5.50/sqft for the overlay and 4.50 for the pathway using decomposed granite. Now I know I don't have enough info and I've got a lot more calls to make. But isn't that way too low for even ballparking a price? I'm just going to add 10% if I can and sub it out.
