Underlayment acts as a cushion, sound dampener, and vapor barrier. It smooths out minor subfloor imperfections and blocks moisture from affecting your planks. Without the correct underlayment, your floor may feel hollow or become susceptible to mold and buckling.

In many cases, no. Many of the premium LVP and laminate products we carry include an integrated pad. However, for installations over a concrete slab, we often recommend adding a 6-mil vapor barrier to prevent coastal humidity and ground moisture from rising through the floor.

Look for products with high IIC (Impact Insulation Class) and STC (Sound Transmission Class) ratings. For multi-story homes or apartments in Santa Cruz County, we carry specialized acoustic underlayments that meaningfully reduce footstep and furniture noise between floors.
