Engineered Wood Flooring Installation in North Mississippi

Strict Subfloor Leveling for a Quiet, Solid Surface

Engineered wood flooring tolerates minor subfloor variation, but exceeding manufacturer tolerances — typically 3/16 inch over a 10-foot span — causes hollow spots, squeaks, and premature joint wear. Before any boards go down, our crew maps the subfloor with a long straightedge, identifies high and low points, and corrects them.

High spots on wood subfloors are belt-sanded or planed down. Low spots are filled with self-leveling underlayment on concrete or floor patch compound on wood. On concrete slabs, we grind high aggregate ridges flush before applying the vapor barrier. This preparation step adds time to the project, but it's what separates a floor that sounds solid and stays quiet for decades from one that develops squeaks and soft spots within a year.

We document subfloor flatness readings and share them with you before installation begins so you can see what condition your substrate is in — useful information if you're planning future renovations.

Moisture Barrier Installation for Slab and Below-Grade Applications

Concrete slabs release moisture vapor continuously — a process called moisture vapor emission (MVE). The rate depends on slab age, local groundwater level, and seasonal conditions. Even a slab that feels bone dry to the touch can have an MVE rate high enough to destroy an engineered wood floor over 12 to 24 months if not properly managed.

TAV Construction tests every concrete slab using ASTM F2170 in-situ relative humidity probes before recommending an installation method. Slabs testing below 75% RH receive a standard 6-mil poly vapor barrier. Slabs testing 75–90% RH require an epoxy or polyurethane moisture mitigation coating before any adhesive or barrier goes down. Slabs above 90% RH require a remediation plan before flooring installation can proceed safely.

We pull this data point for every slab job regardless of how dry a home appears — it protects you from an expensive failure claim and protects our warranty coverage.

Precision Cutting for Vents, Thresholds, and Trim Transitions

Engineered wood installation quality shows itself most clearly at the edges — around floor vents, under door casings, at transitions to tile or carpet, and at thresholds between rooms. Gaps around floor vents collect debris, interrupt visual continuity, and allow moisture ingress. Poorly cut door casing undercuts look unfinished and can crack if boards expand without clearance.

We use an oscillating multi-tool to undercut door casings to the exact thickness of the flooring plus adhesive or underlayment so boards slide cleanly underneath. Floor vents are cut with a router template for tight, repeatable fits. Transitions to other flooring materials use T-molding, reducer strips, or hard seam profiles matched to the flooring color — not generic contractor grade.

Glue-Down or Floating — Matched to Your Home's Structure

The right installation method depends on subfloor type, product specification, and room use. TAV Construction installs engineered wood using three methods:

• Full-spread glue-down — Best for concrete slabs and high-traffic areas. Eliminates hollow spots and floor movement entirely. Requires proper adhesive open time and trowel technique.
• Nail/staple-down — Standard for plywood subfloors over wood framing. Fast, rigid, and refinishable repeatedly over the floor's lifespan. Cannot be used on concrete.
• Floating — Best for rooms where the subfloor has minor movement or the product requires expansion room (e.g., large open-plan areas over radiant heat). Uses click-lock or glued tongue-and-groove assembly.

We'll recommend the appropriate method during your estimate walk-through and explain the trade-offs for your specific room conditions.
