Subfloor Prep is the Secret to Flawless Floors | LeClaire Flooring

Subfloor Preparation Expertise

Proper subfloor preparation is essential for a long-lasting, high-quality floor, but because the condition of the surface cannot be seen until old materials are removed, it is often an unforeseen part of the renovation process. Every space is unique - slabs and subfloors can have hidden dips, cracks or height variations. Once the demolition phase is complete, our team thoroughly inspects the area to determine the exact process, timeline and products needed to create a perfectly level foundation. Best of all, like all our installation services, our subfloor preparation is backed by our Lifetime Labor Warranty.
