    Flooring Demolition & Subfloor Prep: Why It Makes or Breaks Your New Floor

    Flooring Demolition & Subfloor Prep: Why It Makes or Breaks Your New Floor — flooring advice from Genesis Flooring & Renovations in Lakeland FL

    Even the highest-grade $10/sq ft luxury vinyl plank or laminate will fail, click out of place, or squeak if installed over an uneven or poorly prepped subfloor.

    1. Complete Old Floor Demolition

    Old carpet, tack strips, stapled underlayment, or cracked ceramic tile must be stripped cleanly down to the concrete slab or plywood subfloor.

    • Thorough removal of old mortar and thinset ridges.
    • Dust-controlled grinding to ensure a clean bonding surface.
    • Inspection for slab cracks or moisture intrusion spots.

    2. Precision Subfloor Leveling

    Modern click-lock planks require subfloor flatness within 3/16 inch across a 10-foot radius. High spots are ground down and low dips filled with self-leveling cement.

    • Prevents hollow sounds and plank deflection underfoot.
    • Protects click-lock joints from snapping over time.
    • Ensures seamless transition strips between rooms.

    The Genesis Bottom Line

    At Genesis Flooring, Bruce personally inspects and levels every subfloor before laying new materials — guaranteeing a floor that looks and performs flawlessly for decades.
