Laminate Flooring Water Damage: What You Need to Know

Laminate flooring is made of layers, with a fiberboard core that absorbs moisture. When water sits on the surface or seeps into seams, the core swells and the top layer can peel or bubble. Even small spills can cause permanent damage if left untreated.

The damage often shows as cupping, where edges rise, or as dark stains under the surface. You might also notice a musty smell from trapped moisture. The sooner you dry the floor, the better the chance of saving it. If the core is saturated, the planks usually need replacing.

Sometimes you can dry laminate flooring if the water hasn't soaked deep into the core. Use fans, dehumidifiers, and open windows. Keep the room ventilated for several days. If the planks are only slightly damp, they might return to normal.

But if the edges are raised or the surface feels soft, the core is likely damaged. Drying won't fix that swelling. In such cases, the affected planks must be removed. A professional can determine whether spot replacement is possible or if the entire floor needs to go.

To protect laminate flooring, wipe up spills immediately and use mats in entryways and kitchens. Avoid using steam mops or wet mops, as they force moisture into seams. Keep an eye on appliances like dishwashers and refrigerators for leaks. Knowing where your shutoff valve is located can help you act fast in a plumbing emergency.

In a mild marine climate with wet winters and dry summers, moisture can be a year-round concern. Check for leaks under sinks and around windows. If you have a water leak, address it quickly. For major issues, the pros can remove damaged flooring and help prevent mold from spreading.
