All my work is fully guaranteed. If you are not satisfied with the workmanship, return all materials within 10 days and your money will be cheerfully refunded. Materials must be unused, i.e., no glues or mastics on the tiles, no breakage. Returns must be packaged the way they were sent, broken materials will not be reimbursed. If you find any breakage upon arrival, UPS and the USPS deals with it, as all my tile packages are insured. Call them, as they will talk to only the recipient of the package.
