It's so tough to get a decent price for it. Since you got Joe blow who needs 500 bucks he is going to give it away. Example I had a job of about 3k square feet to do and I offered to do it for 1500 since it is down the road from me, they said I was to high and that they had a guy who could do it for 500.
What about Mexican Saltillo that has acrylic sealer . Uneven, large grout lines and most has to be stripped by hand anyone do these tiles?. Messed around with them some years ago ,labor intense. All dirt needs to come off these tiles .who's charging what?
