What is Laminate Floor Bubbling and How to Fix It?

Laminate flooring is an inexpensive alternative to hardwood. It provides the natural appearance of wood with the durability of laminates. But, with qualities of wood, laminate flooring comes with some drawbacks as well.

Since some part of the laminates are made of wood materials, they are susceptible to moisture damage causing various problems. One of those problems is bubbling. Many homeowners complain of floor bubbling but don’t know what causes it and how to fix it.

The flooring installation experts of AA Floors Toronto have drafted this guide to help you with the meaning and treatment of laminate floor bubbling.

What is Laminate Floor Bubbling?

When laminate floors are affected by the moisture content in the air or subfloors, the edges of the laminate boards rise from the subfloor and this is known as bubbling. Another cause of bubbling or buckling is direct water damage. When excessive water on the surface is not cleaned immediately or the floors are wiped with a wet mop, it can lead to bubbles. Sometimes, the absence of an effective moisture barrier or inferior product construction are also causes of the change in the width of laminates.

How to Fix It?

  • Inspect the affected area and find out if only one board is bubbling or a specific part of the floor is damaged. If only one board is causing trouble, it might be because it’s layer has lost cohesion.
  • Use a screwdriver or hammer to replace the wall molding first and then remove the damaged board. If you have a snap and lock laminate flooring, then simply lifting the affected board will be enough.
  • Replace the bubbled board with a new one. Make sure that you get the matching board or else you’ll get an uneven looking floor.
  • After replacing the damaged board, ensure that the floor is sealed to avoid the penetration of moisture or direct water damage in the future.
  • If you have glued down laminate flooring, then make sure to wipe off excess adhesive after installing the new board.
  • If you notice that a large area of the floor is showing bubbles, the reason is inferior product quality. In that case, replacing the existing floor with a high-quality laminate flooring is recommended.

Laminate floor bubbling is a common problem in areas with high moisture level. But, if you live in an area with a dry climate, then prevent your floors from getting in direct contact with water or spills for longer duration that can cause bubbling.
