Floor Repair & Subfloor Preparation in Dallas–Fort Worth TX

Floor repair and subfloor preparation across the Dallas–Fort Worth metroplex. A beautiful floor installed over a bad subfloor will fail — squeaks within months, cracks within a year, and full delamination within five. Southlake Floors fixes the foundation of every flooring project right, before we install anything new. We've repaired subfloors in 500+ DFW homes.

Common subfloor problems in DFW homes

Texas's expansive clay soil moves seasonally — sometimes 2–3 inches over the year. That movement shows up as: cracked tiles, gapped hardwood, popping click-lock planks, squeaky boards, and uneven floors that ball-roll on their own. Pre-2000 Plano, Dallas, and Fort Worth homes are especially prone to slab shifts. New construction in Frisco and Southlake has its own issues: builder-grade subfloor that wasn't properly leveled before the original floor went down.

Subfloor repairs we handle

• Self-leveling compound for uneven slabs (up to 2" variance)
• Plywood subfloor replacement (water damage, rot, soft spots)
• Joist sister-ing for sagging upper floors
• Squeak elimination (Squeeeeek No More fasteners + structural screws)
• Moisture barrier installation before any new floor
• Vapor sealing for slab-on-grade installs
• Termite-damaged floor reconstruction

Why subfloor prep matters more in DFW

Manufacturer warranties on hardwood, LVP, and tile require a flat substrate (typically 3/16" over 10 ft). Skip this step and you void the warranty. Every Southlake Floors install includes a written subfloor flatness report — and we fix any out-of-spec areas before installing.

Schedule a free subfloor inspection — we'll measure flatness, check moisture, and tell you exactly what your subfloor needs before any new floor goes in.
