    Wall or floor tiling-
    The job was supposed to take 4 days and we're currently on day 11 and its still not done. 12 tiles need replacing due to them popping up. Petr does not want to repair them. Multiple issues of no shows for the job and half days with different reasons each time. There is mortor all over our AC unit and siding due to the washing there buckets right beside the house. Also damaged drywall from removing the trim. I would not recommend him.
