We have been waiting seven weeks to have a new hearth fitted. It took ages because the marble had to be custom cut. The company arrived today and I left the two men to get on with it. When they called me in to view the finished product the front and back pieces were completely different colours. The front piece was very similar to the sample (as seen in the photo) but the back was a totally different colour.
I had a long chat with their boss who assured me that the two pieces were cut from the same slab of marble and that colour variations were to be expected but I think this goes way beyond an acceptable colour variation.
The men have taken it away and I'm waiting to hear back from the boss and stonemason.
It is so annoying, I have a huge hole in my wall and until the hearth is fitted and everything made good I cannot get my new stove fitted. And winter is coming.
