What is a floating floor?

A floating floor consists of interlocking planks or boards that are laid over an underlayment but are not fastened (glued or nailed) directly to the subfloor beneath. The planks click together tongue-and-groove style and sit freely on the cushioning material below, allowing the entire floor to move and shift slightly as humidity and temperature change.

This installation method differs from traditional approaches where flooring is either glued down to the substrate or mechanically fastened with nails or staples. Because floating floors are not attached to the base, they can expand and contract without developing gaps, cupping, or other stress-related damage. They are commonly used with laminate, engineered hardwood, vinyl planks, and some solid wood applications, though suitability depends on the specific product and environmental conditions.

For contractors and homeowners in the Greater Toronto Area, floating floors offer practical advantages in basements, kitchens, and other spaces where moisture fluctuation is a concern. The installation is typically faster than nail-down or glue-down methods, and the floor can often be removed and reinstalled if needed. When working with a flooring contractor, it is important to confirm that the subfloor is flat, level, and properly prepared, as a floating system depends on a sound base to perform correctly.
