Tips to Fix Laminate Floor Bubbling | Laminate floor bubbling

Laminate floor bubbling is a common issue that can occur due to moisture, poor installation, or wear and tear over time. While laminate is a popular choice for its affordability and appearance, it’s important to maintain it properly to avoid unsightly bubbles or buckling.

In this comprehensive guide, we’ll explain the causes of laminate floor bubbling, how to fix it, and what you can do to prevent it in the future.

🚨 What is Laminate Floor Bubbling?

Bubbling in laminate flooring refers to the raised or uneven areas that form when the flooring separates from the subfloor or becomes distorted. It typically looks like a bubble or bulge on the surface of the planks.

❓ What Causes Laminate Flooring to Bubble?

Understanding the cause is the first step to fixing the problem effectively:

1. Moisture and Water Damage

Water seeping into the laminate through spills, leaks, or humidity can cause the core to swell and bubble.

2. Improper Installation

Not allowing room for expansion or using incorrect underlayment can result in bubbling due to pressure buildup.

3. Poor-Quality Materials

Cheap or low-quality laminate often has a weaker core that’s more susceptible to damage.

4. High Humidity or Heat

Laminate expands and contracts. If there’s no space for it to move, bubbling can occur.

5. Excessive Cleaning with Water

Mopping with too much water or using a steam mop can weaken the surface layer.

🛠️ How to Fix Laminate Floor Bubbling (Step-by-Step)

🔧 Method 1: Fix Minor Bubbling with Heat

Best for small bubbles on the surface:

Steps:

Use a hair dryer or heat gun on low heat.
Gently warm the bubbled area for 3–5 minutes.
Place a heavy object (like a book) over it to flatten the bubble.
Leave it overnight to set.

⚠️ Caution: Avoid overheating, as this can damage the laminate surface.

🔧 Method 2: Replace the Damaged Plank

If the bubble is too large or caused by water damage, you’ll need to replace the entire plank.

Steps:

Remove the baseboards near the affected area.
Unlock or carefully cut the damaged plank.
Insert a new matching laminate plank.
Lock it into place or glue it depending on the type.
Reinstall the baseboards.

🛠️ Tools Needed: Utility knife, replacement planks, spacers, rubber mallet.

🔧 Method 3: Inject Glue for Small Surface Bubbles

Ideal for minor bubbling with intact planks.

Steps:

Use a syringe to inject wood glue underneath the bubble.
Press down firmly and wipe off excess glue.
Clamp or weigh down the area for a few hours.

✅ Use moisture-resistant glue for better results.

🧼 Tips to Prevent Laminate Floor Bubbling

✅ 1. Clean Spills Immediately

Moisture is your laminate’s worst enemy. Wipe up water or liquids right away.

✅ 2. Use a Dry Mop or Damp Cloth

Avoid wet mopping. A microfiber mop with a damp cloth is best.

✅ 3. Allow Expansion Space

During installation, leave at least a 1/4-inch gap between planks and walls for expansion.

✅ 4. Use a Dehumidifier

In humid climates, a dehumidifier can help maintain proper humidity levels (35–55%).

✅ 5. Avoid Cheap Laminate

Invest in high-quality laminate with a strong HDF core and moisture-resistant layers.

🙋 Frequently Asked Questions (FAQs)

❓ Can I fix laminate floor bubbling without removing the plank?

Yes, small surface bubbles can often be fixed using heat or glue injection techniques.

❓ Will the bubble go away on its own?

No. If left untreated, the bubble may grow or worsen over time.

❓ Can bubbling return after fixing?

It can, especially if moisture issues are not resolved. Make sure to fix the root cause.

❓ What is the best way to dry water under laminate flooring?

Remove the affected planks, use a fan or dehumidifier, and ensure the subfloor is completely dry before reinstalling.

🏁 Final Thoughts

Laminate floor bubbling might seem like a minor issue, but it can become a big problem if ignored. Whether it’s due to moisture, poor installation, or product quality, the good news is — most bubbling issues can be fixed at home with the right approach.
