I used to price on metre. Not anymore.
I also measure and add 10% for cuts. (20% if diamond)
Regardless of price.......if the customer accepts your price, that's it! Weather it's £500 or £1000, they have accepted, regardless of wot others think.
How many times have you had jobs where the customer actually has the tiles already.
They measure themselves, on the back of a *** packet, the supplier works out that they need 20m.......so they sell them 20m.......and then your short, and have to wait until they get more.
I for one add the 10 or 20% for cuts/wastage........and that's wot I charge for.
Each to their own.
I have also always told customers to have a few "spares" just in case some numptie cracks a tile putting up that flashy bog roll holder years later.
It works for me.........and I keep busy. So I must be doing something right.
Happy Crimbo all you bums.
