Recent claims that some Lumber Liquidators‘ flooring contains high amounts of formaldehyde could have ripple effects in the home building industry for years, industry experts say.

As CBS’s “60 Minutes” reported, independent tests of the retail giant’s flooring found levels of the cancer-causing chemical to be off the charts, some close to 20 times above what’s allowed, based on California Air Resources Board (CARB) standards, according to a FGBC newsletter.

Lumber Liquidators insists that the flooring is safe and has questioned the approach the network took to test the formaldehyde levels.

Whether or not the charges are true, the media coverage has set off consumer worries about indoor air quality and the health of homes. Some homeowners are ripping out their Lumber Liquidators flooring, stopping contractors in mid-project, or seeking to have it tested.
