How to Fix Bubbles on Laminate Flooring: 6 Ways to Repair Swollen Planks

Bubbles on your laminate flooring are a sign of possible water damage or air trapped in the subfloor. An insufficient moisture barrier will always cause buckling and bending on the edges of the floorboards as well. So, how can you fix bubbles in laminate floors?

The best way to fix constant bubbling on laminate flooring is to get rid of excess moisture under the planks. Create expansion joints and use a dehumidifier in the room to reduce moisture content causing the bubbles and swelling. You may need to replace the subfloor and the water-damaged planks to maintain a uniform look.

Why is my laminate floor bubbling?

When there are bubbles on your floor, it means there’s a lot of moisture content in your floor’s underlayment and planks.

The laminate floor may feel bouncy and appear buckled due to expansion and contraction triggered by changes in humidity level and moisture build-up over time.

Here are some of the causes of bubbling on the laminate floor:

Moisture damage

High moisture content is the major cause of damage on any solid or engineered flooring. An increase in moisture content will create continuous dampness that can cause bubbling especially when it gets to the laminate core.

Laminate floors are not water-resistant even though they can be waterproof. High moisture content will definitely make your laminate floor swell.

Tension between planks

Bubbling on laminate flooring can be due to too much tension between the planks. In response to temperature changes, the laminate floor will expand and contract. If there are no expansion gaps left the laminate will end up peaking, bubbling, or even buckling. Attaching the molding tightly to the floor may also lead to bubbling.

Water spills and wet mopping

Water spill and pipe leaks that haven’t been taken care of immediately as they happen will leave a swollen laminate floor.

Another problem is wet-mopping. You should not wet-mop or steam clean your laminate floor because of the injection of water or steam into the finish that can easily cause water damage signs such as bubbling and buckling.

Lack of expansion joints

Large area installations require expansion joints or small gaps between the joining sections of laminate boards. Excessively large continuous installations will lead to air bubble being trapped under the laminate boards.

Usually, poor installation methods increase the risk of water damage on wood floors. Ensure you measure your room moisture content before installing laminate. Even when the moisture content is at a normal level ensure its properly installed.

In case you install laminate over wood and concrete subfloors, ensure you don’t interfere with water evaporation and good ventilation of your house. Lack of installation of an effective moisture barrier on your floor may also cause bubbling.

How to Fix Bubbles in Laminate Flooring

In case during the inspection, you find a bubble at the center of the flooring seam. It a sign of inadequate expansion gap that forces then boards to squeeze and swell on seams.

Remove the Wall Molding

Removing the laminate wall mold near the damaged laminate board with air bubbles. Remove the mold carefully with hammer and screwdriver to avoid damaging the laminate floor molding.

Remove the Laminate Board

After removing the wall mold, remove laminate boards one by one until you reach the damaged. Slip the floorboard carefully from the locking mechanism with the connecting board.

Where the bubbling was a result of an inadequate expansion gap, you just need to fix the floor by relieving the board’s tension. Check the gap between the board and wall at ensuring its about 1/4 to 1/2 an inch. Fix it by cutting the board near the wall.

Replace the Damaged Laminate

Slide the new matching laminate floorboard in place of the damaged one. Insert the tongue of the board carefully into the groove of the next board. In cases of the peaked board, you just need to place a weigh on top of the peaked board after providing appropriate gap. This would help the flooring floor to settle without any other intervention.

Return the Flooring

Return the other undamaged floorboards to their initial place. Inspect your floor carefully to ensure there are enough expansion and contraction gap pon your laminate flooring.

Tip: Ensure the newly installed plank board matches the other planks to avoid color mismatch on your flooring.

Provide Appropriate Expansion Gap

Ensure you leave 1/4 to 1/2 of an inch expansion and contraction gap to avoid laminate peaking problems down a week or month. Below is a video of how to replace the water damaged laminate board.

Glued joints can swell slightly as they absorb water from the glue. This bubbling problem tends to resolve itself with time, within 2-3 weeks.

Sometimes a simple popping method may be used to get rid of the air bubble on the laminate flooring. Here a video of how to repair laminate without replacing using the busting method as explained in bellow video.
