The short answer
What Causes the Bubbles
Laminate flooring is made of layers with a fiberboard core. That core absorbs water easily. When moisture gets in, the core swells and pushes up the surface layer, creating bubbles or blisters. Spills left to sit, a leaking dishwasher, a dripping refrigerator line, or a slow pipe leak can all introduce enough moisture to cause this.
High humidity can also be a factor. In a humid subtropical climate, summer air holds a lot of moisture. If your home lacks proper ventilation or a dehumidifier, the laminate can take on moisture from the air over time. Even a small amount of trapped water under the floor can lead to bubbling.
Can You Fix a Bubble
Once the fiberboard core swells, it does not shrink back. You might be tempted to puncture the bubble to let the water out, but that usually makes the damage worse. The surface layer is not designed to be repaired. In most cases, the affected planks need to be removed and replaced.
If the bubbling is minor and confined to a small area, you might try to flatten it with a heavy object and heat, but this is rarely effective. The honest answer is that replacement is the reliable fix. The longer you wait, the more likely the damage spreads to neighboring planks.
- Wipe up spills immediately
- Check appliance connections for leaks
- Use a dehumidifier in humid months
- Inspect the floor after any water event
- Keep a mop and dry cloth handy
- Avoid excessive water when cleaning
Find the Water Source First
Before replacing planks, you need to know where the water is coming from. A leak can be hidden behind walls or under the floor. If you see bubbling, look for other signs like a damp baseboard, a soft spot nearby, or a musty smell. Identifying the source prevents the problem from happening again.
If you suspect a pipe leak, a plumber can help locate it. For hidden moisture, a water damage inspection can map out the affected areas. Moisture mapping tools can detect dampness without tearing up your floor. Knowing the source is the first step to a lasting fix.
When to Call the Pros
If the bubbling covers a large area or you cannot find the source, it is time to call local water damage pros. They have the tools to extract standing water and dry out the structure. They can also remove the damaged flooring safely, especially if mold is starting to grow.
The pros will assess the extent of the damage and help you plan the next steps. They can perform emergency water extraction and structural drying to reduce further harm. For extensive damage, they may recommend full floor replacement. Their work focuses on making the area safe and ready for new flooring.
Preventing Future Bubbles
Prevention starts with controlling moisture. Use rugs in areas prone to spills, like the kitchen and entryways. Wipe up any liquid right away. Check the seals around sinks and appliances regularly. In humid climates, keep a dehumidifier running during the summer months to lower indoor moisture.
Also, be mindful of cleaning methods. Never wet-mop laminate flooring; use a barely damp cloth instead. Dry any spills immediately. If a leak happens, act fast. The longer water sits, the more likely bubbles will form. Quick action can save you from a costly replacement.
Water damage does not wait
Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Will the bubble go away on its own?
No. Once the core swells, it stays swollen. The bubble will not flatten out over time. You might reduce it slightly with weight and heat, but that is not a reliable fix. Replacement is the only lasting solution.
Can I just replace one plank?
Yes, if you have spare planks from the same batch. The pros can remove the damaged plank and click in a new one. But if the color or style is discontinued, matching may be hard. Check your records first.
Will my insurance cover the damage?
Policies vary, and your insurer decides what is covered. Water damage from a sudden leak is often covered, but gradual damage from humidity may not be. Check your policy and document the cause. If you file a claim, your insurer will guide you.
