First, remember that tile or marble flooring problems are usually related to installation issues. An industry study of claims found that installation problems were the cause nearly 70 percent of the time while inadequate maintenance was the culprit about 20 percent of the time. Erroneous specifications were to blame in 8 percent of claims, while manufacturer errors accounted for just 2 percent. (So much for the blame-the-manufacturer strategy some installers like to employ.)
