Subfloor Repair & Stair Trim

Subfloor Leveling, Structural Repair & Custom Stair Installation

Eliminate floor squeaks, level uneven concrete slabs, and install seamless stair noses and treads before laying your new surface.

The Challenge

The Foundation of Every Lasting Floor

Installing expensive wood or LVP over an uneven slab, rotten plywood, or creaking floorboards guarantees long-term floor failure. Ignoring subfloor defects causes click joints to break, tile to crack, and floors to bounce underfoot.
