Laminate floors require very little maintenance. The material handles surface moisture well, but if the core material gets wet it can expand and damage the flooring. In bathrooms and kitchens, make sure that surface water is wiped up after spills and over spray. Unlike hardwood, laminate does not require sanding and refinishing every few years. Routine cleaning with a vacuum or damp mop is all that is needed. The process for repairing damaged boards is similar to that of hardwood. Precision cutting and fitting is required, so a professional should be hired to replace any damaged pieces.
