Wood Flooring Installation: Details Dictate Success! Crucial Points to Monitor

Wood flooring is "30% product, 70% installation." Poor install can ruin the best floor. Monitor these critical steps:

Pre-Installation Prep:

1. Subfloor Flatness is Foundational: Must be clean, dry, solid, LEVEL! Use a 2m straightedge. Deviations ≤3mm. Concrete must be fully cured (MC ≤ local standards, often ≤20% or lower). Level with compound if needed. Unlevel floors cause squeaks, crowning, breakage.

2. Thorough Sweeping/Vacuuming: Any grit causes noise and wear later.

3. Install Underlayment: Vital! Use quality underlay (PE foam, cork). Seal seams with tape. It blocks moisture, adds cushion, reduces noise. Use UFH-specific underlay for heated floors.

4. Acclimate the Flooring: Leave unopened boxes onsite for ≥48 hours (especially solid/engineered) to adjust to room temp/humidity, reducing warping risk.

During Installation:

1. Plan Layout Direction:

   • Usually parallel to main light source (perpendicular to windows) looks best, hides seams.

   • In long rooms (hallways), run lengthwise for spacious feel.

   • Avoid perpendicular to doorways (unless very short) to prevent narrow end pieces.

   • Consider transitions to adjacent rooms (continuous or transition strips).

2. Leave Expansion Gaps: Critical! Leave gaps (8-12mm typically) around all walls and fixed objects (columns, platforms). Cover with baseboard/quarter round. Floors expand/contract – no gap = guaranteed crowning! Use T-molds/U-molds at doorways or long continuous runs.

3. Secure Locking Joints: Ensure clicks lock fully. Use a tapping block gently – don't damage tongues. Check for uniform seams and no height differences.

4. Prevent Squeaks: Uneven subfloor, poor underlay prep (debris, tears), loose locks, or insufficient gaps cause noise. Be meticulous at every step.

5. Minimize Waste: Smart layout reduces waste (typically 5%-10%). Mix planks from multiple boxes for color blending.

6. Installer Skill: Choose experienced, reputable installers, ideally brand-certified or authorized.

Post-Installation Check:

1. Walk the Floor: Feel for looseness, squeaks, or noticeable unevenness.

2. Inspect Details: Check seam uniformity (minor natural gaps ok), adequate hidden expansion gaps, secure/neat baseboard & transition strips, clean edges against walls/door casings.

3. Protect: Clean immediately post-install. Lay protective sheeting to prevent damage during finishing work.

What to Monitor:

• Is the subfloor truly flat?

• Is the underlay smooth and seamless?

• Are expansion gaps sufficient (especially walls)?

• Are the locks tight? Seams small?

• Are installers careful (no excessive force, clean cuts)?

• Is trim installed securely and neatly?

Remember: Attention during install prevents post-move-in headaches!
