Mold beneath floating floor

My niece and her husband just had PERGO floors installed in their foyer and kitchen. The contractor warned them that now they would have a problem with mold and mildew between the floor and the plastic pad below if those floors ever get wet.

We were just ready to install PERGO over our subfloor and we are now wondering how do you avoid the mold and mildew problem? We have purchased the snap together kind that does not use glue.

Mold beneath floating floor

Mold and mildew beneath floating floor products are not an issue if there are no moisture problems. Moisture problems can originate from concrete subfloor or damp crawl space. Tape a piece of clear plastic 2 feet x 2 feet to the floor with duct tape for 24 hours or more. If there are moisture/condensation droplets on the under the plastic or you see discoloration, then you should have a professional moisture test done and corrective measures taken to address moisture issues before installing flooring according to manufacturer's instructions.

After flooring is installed, follow manufacturer's recommendations for maintenance and care. Avoid introducing moisture into the floor from overwetting when cleaning. Wipe up spills immediately. Plumbing leaks and floods that introduce moisture beneath the floor covering can result in mold/mildew problems.

The EPA web site is down for maintenance today but I think this is the correct address for mold information.EPA Mold and Moisture Info

Moisture is THE cause of mold. That said, it is wise to become knowledgable, floating floor or not. Most mold is not very toxic but that which is, brings big trouble.

Plastic sheeting such as used under a laminate floor will not support mold. Mold grows on organic and fiberous materials. There is a large amount of information on the Internet including scare stories from lawyers and reclaimation firms selling their services so before fear strikes it's a good idea to search out the facts. The Federal Government's EPA and CDC are to good places to start.
