Top 10 Most Common Mistakes When Installing LVP Flooring

1. Not Allowing the Planks to Acclimate
Skipping acclimation is one of the biggest LVP flooring installation mistakes.
LVP expands and contracts with temperature and humidity changes. If you install it straight from the box, it might buckle or form gaps later.
Tip:
Let your planks sit in the installation room for 24–48 hours to adjust to the environment. This simple step prevents LVP expansion and contraction issues down the road.
2. Skipping Subfloor Preparation
Think you can just lay planks over your old floor? Think again.
A clean, dry, and level surface is key. If you skip subfloor preparation for LVP, even tiny bumps or debris can cause uneven seams or creaks later.
Tip:
Sweep, vacuum, and check for moisture before installation. If needed, apply a moisture barrier for vinyl flooring to protect from dampness below.
3. Ignoring Moisture Levels
Ignoring moisture is another common vinyl plank flooring installation error — especially in basements or bathrooms.
Too much moisture can lead to warping, mold, or lifting planks. Always use a moisture meter to check the subfloor before starting.
Tip:
Keep humidity between 30–50% and ensure your subfloor is completely dry.
4. Installing Over Uneven Surfaces
Even the smallest dips can cause luxury vinyl plank installation problems. Planks might shift, separate, or squeak when walked on.
Tip:
Use a floor leveling compound to smooth out the surface. An uneven subfloor under vinyl plank flooring will always lead to trouble later.
5. Not Leaving Expansion Gaps
One of the most overlooked steps when installing floating vinyl floors is leaving enough expansion space.
Without a proper expansion gap, your floor has nowhere to move as it expands, leading to buckling or lifting.
Tip:
Leave at least a ¼-inch gap around walls, pipes, and door frames to allow for natural movement.
6. Mixing Planks from Different Boxes
Every box of LVP might have slight color or texture variations. Installing one box at a time can create awkward patterns.
Tip:
Mix planks from three or four boxes before installation for a natural, random look — just like real wood floors.
7. Incorrect Underlayment Use
Using the wrong underlayment is a beginner mistake in vinyl flooring installation.
If your planks already have attached padding, adding another layer can cause instability or floating floor problems.
Tip:
Check your manufacturer’s guide for underlayment for LVP flooring — not all floors need one.
8. Poor Cutting or Wrong Direction
Installing LVP against the direction of natural light can make seams more visible. Poor cutting can also lead to gaps and uneven edges.
Tip:
Lay planks parallel to the main light source and use a proper flooring cutter or utility knife for clean cuts.
9. Forgetting to Stagger Seams
Lining up seams creates weak spots and looks unnatural.
Tip:
Always stagger vinyl plank seams by at least 6 inches from one row to the next. This makes the floor stronger and more visually appealing.
10. Not Following Manufacturer Guidelines
Every brand has its own click-lock system and specific requirements. Skipping the manual can void your warranty or lead to installation failures.
Tip:
Always review your LVP installation checklist and follow manufacturer recommendations to the letter.
Bonus Tips for a Flawless LVP Installation
If you want your new floor to look like a professional job, keep these extra tips in mind:
- Keep tools ready — rubber mallet, tapping block, spacers, and pull bar.
- Work from the most visible wall outward.
- Double-check each row before locking it in place.
- Clean gently with a microfiber mop after installation.
These small details can prevent common vinyl plank flooring problems and give your space that sleek, high-end finish.
