Just had a quote from a local tradesman come through for tiling a c 7' x 8' hallway in natural stone: £1200 labour, £316 materials. Also for the same tiling in a dining room c 24' x 12' ; £4496. This would include levelling/screed as the floor is just rough chipboard. Seems really extortionate to me but maybe I am just out of touch, any thoughts? Thank you.
