3 Best Mistakes to Avoid in Plank Flooring Installation

Installing plank flooring—whether it’s hardwood, engineered wood, or luxury vinyl—is a valuable upgrade for any home. It enhances aesthetics, increases property value, and brings a sense of warmth and elegance to interior spaces. However, the process of installing plank flooring isn’t foolproof. Even skilled DIYers or contractors can make critical mistakes that affect the floor’s durability, appearance, and performance.

In this article, our flooring experts at Millennium Hardwood Flooring in Austin, TX share the top three mistakes to avoid during plank flooring installation—based on real experience in residential and commercial projects across Central Texas.

1. Failing to Acclimate the Flooring Material Properly

One of the most common—and most damaging—mistakes is skipping the acclimation process. Many homeowners or installers are eager to jump into installation after delivery, but this impatience can lead to serious consequences down the road.

Why Acclimation Matters

Plank flooring materials like solid hardwood and even engineered wood react to humidity and temperature. If planks are installed straight out of the box without time to adjust to the environment, they may expand or contract after installation, resulting in cupping, gaps, or buckling.

Best Practice

Before installation, let the flooring material acclimate for at least 48 to 72 hours in the room where it will be installed. Open the boxes and spread out the planks so air circulates around them. For solid hardwood, a longer acclimation time (up to 5 days) may be recommended, depending on the season and humidity levels in Austin.

Expert Tip: Use a moisture meter to ensure both the subfloor and flooring are at equilibrium moisture content (EMC) before installation. This small step prevents costly callbacks and damage.

2. Ignoring Subfloor Preparation

No matter how high-quality your plank flooring is, it will only perform as well as the foundation it’s laid on. Ignoring subfloor issues is a recipe for squeaks, uneven surfaces, and early wear.

Common Subfloor Issues:

Uneven surfaces (more than 3/16 inch difference over 10 feet)
Moisture problems in concrete slabs
Loose or damaged plywood in wood subfloors
Debris or adhesive residue left behind from previous flooring

Best Practice

Before laying down any planks:

Check for level using a long straightedge.
Fix low spots with leveling compound and sand down high spots.
Check moisture levels in concrete with a calcium chloride test or RH probe.
Clean thoroughly to ensure no grit or dust interferes with the installation.

Pro Insight: At Millennium Hardwood, we always include a thorough subfloor inspection and preparation step in every job. It’s the foundation of a long-lasting installation.

3. Not Leaving Proper Expansion Gaps

Another critical mistake is failing to leave the correct expansion gaps between the floor and the walls. This oversight is especially problematic in climates like Texas, where temperature and humidity can fluctuate drastically between seasons.

Why Expansion Gaps Are Essential

Plank flooring needs room to expand and contract with environmental changes. Without a gap, the flooring may press against the walls and buckle or lift, creating unsightly and potentially dangerous conditions.

Best Practice

Leave a minimum 1/4-inch gap around the perimeter of the room, including at doorways, columns, and other fixed objects. This space is typically hidden under baseboards or quarter round trim.

Did You Know? Even luxury vinyl plank (LVP) and engineered wood floors need this expansion space—especially in large rooms or open-plan areas.

Bonus Mistake: Using the Wrong Underlayment

Choosing the right underlayment is crucial for performance, moisture control, and sound absorption. Using the wrong one—or skipping it altogether—can lead to a noisy, uncomfortable, or moisture-prone floor.

Considerations when choosing underlayment:

Moisture barrier (especially on concrete)
Sound insulation (for upstairs installs)
Cushioning (for comfort and durability)

FAQs

A: For smaller rooms and floating floors, it’s possible. But for glued or nailed installations—or expensive hardwood—professional help is strongly advised.

Q: What’s the best season to install plank flooring in Texas?
