How Does Water Damage Laminate Flooring?

Laminate flooring is a manufactured product with multiple laminated layers. The top is a clear wear layer protecting a printed decorative image. Beneath that is a dense fiberboard core, which provides stability. A backing layer sits on the bottom. This construction looks like wood but lacks solid wood's resilience. When water penetrates, the core absorbs it readily, causing irreversible damage.

You will notice physical changes in the floor's appearance and feel. Planks may separate at the seams or push against each other, causing ridges. The fiberboard core expands when wet, distorting the planks permanently. These signs mean water has compromised the material's integrity. Prompt action is crucial to prevent further damage to the subfloor and potential mold growth beneath the flooring.

• Buckling or lifting planks that no longer lie flat.
• Warping or cupping where edges curl upward.
• Visible swelling along the seams and plank ends.
• A spongy or soft feeling underfoot when walking.
• Discoloration or dark water stains on the surface.
• A musty odor indicating moisture is trapped underneath.

Your first priority is to limit the extent of the damage. Extract as much water as you can safely. Then, focus on drying the area thoroughly. However, because water gets trapped, you often need a professional assessment. Local water damage pros have tools to detect moisture in the subfloor and can determine if removal is necessary. This helps protect your home's underlying structure. If you have insurance, review your policy and document the damage. Policies vary, and your insurer decides what is covered.

• Stop the water source immediately, if possible.
• Remove any standing water using a wet vacuum or mop.
• Move furniture and rugs off the wet area promptly.
• Increase airflow with fans and use a dehumidifier.
• Lift baseboards to allow air to reach the wall edges.
• Document the damage with photos for your records.
