It's a moment every homeowner dreads—discovering water beneath your laminate flooring. Whether from a leaking appliance, overflowing sink, or external flooding, water intrusion can threaten even the best laminate flooring. While laminate flooring installation typically includes measures to resist minor moisture, significant water exposure requires immediate action. The good news? With the right approach, you may be able to save your floors and prevent costly damages.
Understanding how water affects laminate flooring
Most laminate flooring consists of four main layers: a wear layer, a design layer, a core board (typically high-density fiberboard or HDF), and a backing layer. The core board is most vulnerable to water damage as it's made of compressed wood fibers that absorb moisture, causing swelling and deformation.
Even cheap laminate flooring typically includes some water-resistant features, but no laminate is completely waterproof. When water seeps beneath the planks, it can cause:
- Swelling along the edges (peaking)
- Warping and buckling
- Separation between planks
- Staining and discoloration
- Mold and mildew growth
The severity of damage depends on how quickly you respond and how much water has accumulated.
Immediate steps when you discover water
- Identify and stop the source: Before anything else, find where the water is coming from and stop it. Turn off water supplies, fix leaks, or block external water entry.
- Remove standing water: Use towels, a wet vacuum, or a mop to remove any visible water from the surface of your laminate flooring. Work quickly but thoroughly.
- Assess the extent of seepage: Water can travel far beneath laminate flooring. Check for "squishy" areas, visible edge swelling, or a change in sound when walking (a hollow or squishy sound often indicates water underneath).
Drying out your laminate floors
For minor water exposure:
- Create airflow: Position fans to blow across the floor surface. Aim for maximum air circulation.
- Reduce humidity: Run dehumidifiers in the affected room to draw moisture from both the air and the flooring materials.
- Apply gentle heat: Maintain room temperature slightly warmer than normal (around 75-80°F) to accelerate evaporation without causing too-rapid drying that might lead to cracking.
For more significant water intrusion:
- Remove baseboards: Carefully pry off baseboards along affected walls to allow better airflow at the edges where water often collects.
- Consider partial floor removal: If only a section shows damage, carefully disassemble the affected planks working from the wall toward the damage. Document the layout for reassembly.
- Inspect and dry the subfloor: Once you've removed damaged planks, check the subfloor for moisture and use fans and dehumidifiers to thoroughly dry it before reinstalling flooring.
When to call professionals
While DIY drying works for minor issues, certain situations call for professional help:
- Water has been present for more than 24 hours
- The area affected is large (more than a few square feet)
- You notice a musty smell indicating potential mold growth
- The source was contaminated water (from sewage backup, for example)
- The subfloor shows signs of damage
Professional water restoration services have specialized equipment like commercial-grade dehumidifiers and moisture meters that can detect hidden moisture within your flooring system.
Preventing future water damage
Once your current issue is resolved, take steps to prevent recurrence:
- Regularly check water-using appliances for leaks
- Consider water leak detection systems
- Apply additional sealant to laminate edges in moisture-prone areas
- Wipe up spills immediately
- Maintain proper humidity levels in your home
When replacement is necessary
Sometimes, despite your best efforts, laminate flooring damaged by water cannot be saved. Signs that replacement is needed include:
- Persistent buckling or warping after drying
- Visible mold growth on or between planks
- Separation between planks that won't close
- Soft or spongy areas that don't firm up after drying
