10 Common Mistakes When Installing Vinyl Plank Flooring (And How to Avoid Them)
Introduction
Vinyl plank flooring has become one of the most popular flooring choices for homeowners and businesses. It’s durable, waterproof, and budget-friendly, making it an excellent option for high-traffic areas, kitchens, and even basements. Plus, with modern click-lock and glue-down installation methods, many DIY enthusiasts tackle the installation themselves.
However, while vinyl plank flooring is easier to install than hardwood or tile, small mistakes can lead to big problems—uneven surfaces, gaps, buckling, and even long-term damage. If you want a flawless, professional-looking floor, it’s important to avoid these common pitfalls.
In this guide, we’ll go over 10 common mistakes when installing vinyl plank flooring and how you can prevent them to ensure a smooth, long-lasting installation.

1️⃣ Not Preparing the Subfloor Properly
One of the biggest mistakes when installing vinyl plank flooring is failing to prepare the subfloor. While vinyl is designed to be flexible and forgiving, an uneven or dirty subfloor can lead to visible bumps, gaps, and long-term damage.
How to Avoid This Mistake:
- ✅ Clean the Subfloor Thoroughly – Remove all dust, debris, and adhesives to ensure a smooth surface. Even small particles can create lumps under the planks.
- ✅ Check for Uneven Spots – Use a level to check for dips or high spots. If needed, use a floor patching compound or self-leveling underlayment to correct uneven areas.
- ✅ Moisture Test (For Concrete Subfloors) – If installing over concrete, test for excess moisture. High moisture levels can cause warping, adhesive failure, or mold growth. A vapor barrier or moisture-resistant underlayment may be needed.
- ✅ Confirm the Subfloor Type – Vinyl plank flooring can be installed over plywood, concrete, or even existing tile, but some surfaces may require additional prep work or underlayment.
💡 Pro Tip: Never install vinyl plank flooring over carpet or a heavily cushioned surface—it will lead to movement and uneven planks!

2️⃣ Skipping Acclimation
Vinyl plank flooring may be waterproof and durable, but it’s still sensitive to temperature and humidity changes. If you install it right after delivery, the planks may expand or contract once they adjust to the room’s environment—leading to gaps, buckling, or misaligned seams.
How to Avoid This Mistake:
- ✅ Let the Flooring Acclimate – Store the boxes of vinyl plank flooring in the room where they will be installed for at least 24–48 hours before starting. This allows the planks to adjust to the room’s temperature and humidity levels.
- ✅ Maintain a Consistent Room Temperature – Keep the space at a stable temperature (between 65°F and 85°F) before, during, and after installation. Extreme cold or heat can cause planks to shrink or expand.
- ✅ Stack the Boxes Flat – Do not leave the boxes standing on their sides. Lay them flat to ensure even acclimation and to prevent planks from bending.
💡 Pro Tip: If you’re installing vinyl plank flooring in a basement or humid area, consider using a dehumidifier for a few days before installation to prevent moisture-related issues.

3️⃣ Incorrect Expansion Gaps
Vinyl plank flooring may look solid once installed, but it expands and contracts slightly with temperature and humidity changes. Failing to leave proper expansion gaps can result in buckling, warping, or planks pushing against walls.
How to Avoid This Mistake:
- ✅ Leave a ¼-Inch Expansion Gap – Always leave at least ¼ inch of space between the flooring and the walls, baseboards, cabinets, or any fixed objects. This allows the flooring to move naturally.
- ✅ Use Spacers During Installation – Place small spacers between the planks and the walls to ensure an even expansion gap all the way around the room.
- ✅ Don’t Install Planks Too Tight – For floating floor installations, avoid forcing planks too snugly together. Over-tightened planks may buckle when they expand.
- ✅ Account for Room Size – In larger spaces (over 30 feet in length or width), consider using expansion joints or transition strips to allow for additional movement.
💡 Pro Tip: After installation, cover the expansion gap with baseboards or quarter-round molding for a clean, finished look!
