March 18, 2015 — Lumber Liquidators is offering customers a free at-home test kit to check formaldehyde emissions from flooring, and may replace floors that emit toxic levels of the cancer-causing chemical.

NBC News reports that Lumber Liquidators has sent 3,000 to 5,000 of the kits to customers.

Customers who are interested in requesting and using the test should fill out the online questionnaire to determine eligibility, located at

The lab will send the kit with same-day shipping through USPS Priority Mail. The test kit will include a plastic disk tester and instructions. Following instructions, the disk is placed at least four feet off the ground in an area where the flooring is installed. After 24-48 hours, the test disk is returned to the lab and results are emailed to the customer within 7-10 business days.

Lumber Liquidators has not stated whether they will pay to remove and replace floors that are over the acceptable threshold for formaldehyde emissions.

Instead, customers whose floors fail the test will need to run more tests, which may include particle counts, “thermography,” and taking samples of other materials in the home (such as kitchen cabinets) to test for formaldehyde.

Lumber Liquidators CEO Robert Lynch said, “Once a full analysis of a home’s air quality is completed and, if the customer is still not satisfied, we will consider a reinstallation.” He anticipates reinstalling the floors will cost between $3,000-4,000 each.
