Hi philzero,
I guess I failed to give you the entire story. I understand the need for wastages and extra materials and supplies that will be used for the laying and skirting. The cost for all these materials and supplies were included in the quotation. I managed to get quotations from 4 other contractors as well and when we made comparisons, the other quotations seemed more reasonable (I had discussed with them and the cost of wastages and materials for laying and skirting was also included in their quotations) - I discovered that I was being ripped off by about $14,000. This $14,000 was distributed here and there in the labour costs over and above the actual labour costs. I had 4 quotations that had reasonable pricing differences of +/- $2K to $4K. But this greedy contractor had a difference of $14K - I felt that was a ridiculously large amount. Adding to this, he was reluctant to discuss with us the process of tiling and just kept insisting that "It's a lot of work". Having discussed with several friends who had also done tiling works in their homes and also having the additional quotations from 4 other contractors, it was clear we were being fleeced. This contractor was unhappy when we asked if we could purchase the tiles ourselves. He was also reluctant to accompany us to the tile shops and showrooms, it became obvious to us that he wanted us to purchase tiles through him alone. The other 4 contractors were happy to accompany us to the tile showrooms for us to arrange for the purchase of tiles.
There are lots of contractors who are willing to be transparent with their costs. There are also contractors who manipulate numbers and hope that their customers don't notice. Some home owners don't really scrutinize a contract or discuss the materials and supplies with their contractors.
