Grinding, Self-Leveling, and Tear-Out: The Prep Work Behind a Floor That Lasts

When people picture a flooring project, they picture the finished floor. But a lot of what decides whether that floor stays flat, quiet, and tight for years happens before a single plank or tile goes down. Here's a look at the prep stage our crew handles on most jobs - and why we don't skip it.

Step One: Tear-Out

Before anything new goes in, the old floor has to come out - along with the adhesive, staples, or mortar left behind. Old tile removal is the most labor-intensive, since thinset has to be scraped or ground away. We work to keep dust and disruption contained to the work area as much as possible.

Step Two: Grinding High Spots

Concrete slabs and older subfloors are rarely perfectly flat. Ridges, old adhesive, and high spots can telegraph through a new floor or create gaps underneath it. On concrete, we grind those areas down so the surface is flat and clean enough for the next step.

Step Three: Self-Leveling Low Spots

Where the floor dips, a self-leveling compound is poured and spread to create a flat surface. It's one of the most important steps for luxury vinyl plank and laminate, which can flex and separate at the seams over dips, and for tile, where an uneven base leads to lippage and cracked grout.

Why It Matters for Each Floor Type
