Frequently Asked Questions
Why do I need a 10% waste factor for flooring?
Cutting planks to fit wall borders, corners, doorways, and closets results in unusable offcuts. A 10% buffer ensures you do not run out mid-installation.
How much extra flooring should I keep for repairs?
It is recommended to retain at least one unopened box of flooring in the attic or closet for future plank replacement in case of moisture damage or scratches.
