I would appreciate some advice here, I have 750 to 800m2 to tile, of which 600m2 is on the floor. I had a tiler quote me £15/m2 for labour only. I supplied all the materials. I have been on holiday for the past week. The tiler has been working for around 8 days and has done a minimum of 200m2 so far (big flat open areas and long plank like tiles). Unfortunately the tiler is not happy, the floor is not level so he has had to bed up the adhesive a lot. We are probably using 70% more adhesive than expected, so now he wants £20/m2. So is this reasonable? or should I find someone else to work on a day rate? I would assume a good tiler would charge around £175 per day. I think the guy I have is doing a very good job but on the other hand I think he is making a LOT of money per day so I dont really think I should pay anymore? So any tilers here want to give me some advice?
