Laminate flooring is a popular choice for its durability and affordability. However, it's not waterproof. Water damage can lead to significant problems if not addressed quickly. This article details what happens when water seeps under your laminate, and how to mitigate the damage.

Understanding Laminate Flooring and Water

Laminate flooring is made of layers pressed together: a wear layer, a decorative layer, a core layer (often HDF), and a backing. While the top layer is resistant to spills, the core is highly susceptible to water damage. Water penetration can cause irreversible damage, potentially ruining your floor and requiring costly repairs or replacement.

Immediate Effects of Water Under Laminate

The immediate effects depend on the amount of water and how long it remains. Small spills quickly wiped up usually cause no harm. However, larger amounts of water, leaks, or prolonged exposure can lead to:

• Buckling: The core layer expands when it absorbs water, causing the laminate planks to swell and buckle. This is often visible as raised sections of flooring.
• Cupping: The edges of the planks may lift up, creating a cupped or concave appearance. This is another sign of moisture expansion.
• Separation: The planks can separate at the seams, creating gaps and instability.
• Mold and Mildew Growth: Standing water provides the perfect breeding ground for mold and mildew, especially in dark, damp areas. This can lead to serious health issues.
• Discoloration: Water can stain the laminate, leaving unsightly marks that are often impossible to remove.

Long-Term Damage from Water Ingress

If the water damage isn't addressed, the problems worsen:

• Structural Damage: Continued expansion can cause warping and permanent deformation of the flooring. This isn't just cosmetic; it affects the structural integrity of the floor.
• Subfloor Damage: The water can seep through to the subfloor, causing rot and decay in wood subfloors, or damage to concrete subfloors. This requires extensive repairs.
• Health Hazards: Mold and mildew growth can cause respiratory problems, allergies, and other health issues. Addressing this requires professional remediation.

How to Deal with Water Under Laminate Flooring

Immediate action is crucial:

1. Identify the Source: Find and fix the source of the leak immediately. This might involve a plumber for plumbing leaks or a roofer for roof leaks.

2. Remove Standing Water: Use absorbent towels, sponges, or a wet vacuum to remove as much water as possible. The faster you act, the less damage will occur.

3. Increase Air Circulation: Open windows and doors to increase ventilation and help the floor dry. Use fans to circulate air directly over the affected area.

4. Remove Affected Planks (If Necessary): If significant buckling or cupping has occurred, you may need to remove the damaged planks. This often requires replacing the entire section.

5. Professional Help: For extensive water damage or if you're unsure how to proceed, call a professional water damage restoration company. They have the tools and expertise to properly assess and repair the damage.

6. Prevention is Key: Consider these preventative measures to minimize future issues:

• Regularly Inspect for Leaks: Check regularly for any signs of leaks or water damage.
• Use Rugs or Mats: Place rugs or mats in high-traffic areas and near entryways to help absorb spills.
• Improve Ventilation: Ensure good ventilation in areas prone to moisture.

When to Call a Professional

Don't hesitate to contact a professional if:

• Extensive Water Damage: Large areas of the floor are affected.
• Mold or Mildew Growth: You suspect mold or mildew growth.
• Subfloor Damage: You suspect the subfloor is damaged.
• Unsure How to Proceed: You're unsure how to properly address the water damage.

Dealing with water under laminate flooring requires prompt action. While small spills are manageable, significant water damage can lead to costly repairs. Preventative measures and quick response are your best defenses. Remember, addressing the issue promptly minimizes long-term problems and protects your health and your investment.
