Moisture is one of the biggest threats to laminate flooring, as excess moisture can lead to warping, swelling, and mould growth. Testing laminate flooring for moisture helps you detect problems early and prevent costly damage. Whether you’re installing new laminate or checking an existing floor, here’s how to test for moisture effectively, the tools you’ll need, and tips for keeping your floors safe.
Laminate flooring is sensitive to moisture, and even small amounts can cause significant issues over time. When laminate absorbs moisture, it can swell and lose its shape, which may result in lifting or buckling. In some cases, high moisture levels can also lead to mould growth, especially if moisture is trapped under the floor. By testing for moisture, you can catch these problems before they become major concerns and ensure that your floor stays in excellent condition.
Testing laminate flooring for moisture is straightforward if you have the right tools. Here’s what you’ll need:
There are two common methods to test laminate flooring for moisture: using a moisture meter or performing the plastic sheet test. Here’s how to do each method:
1. Using a Moisture Meter
A moisture meter is the most reliable way to test moisture levels in laminate flooring.
2. The Plastic Sheet (or Ziploc Bag) Test
The plastic sheet test is a simple, DIY way to gauge if there’s moisture coming up from beneath the floor.
Knowing the acceptable moisture levels for laminate flooring is essential to determine whether action is needed. For most laminate floors, moisture levels should be below 12%. Anything higher may indicate an issue, such as moisture seeping up from the subfloor or high humidity in the room.
If testing reveals high moisture levels, it’s essential to address the issue promptly to protect your laminate flooring. Here are some steps to consider:
1. Improve Ventilation
Poor ventilation can contribute to high indoor humidity. Use exhaust fans, open windows, or run a dehumidifier to improve air circulation and control moisture levels.
2. Use a Dehumidifier
In areas with high humidity, especially basements or bathrooms, a dehumidifier can help maintain ideal moisture levels. Set it to maintain humidity between 40-60% for best results.
3. Address Subfloor Moisture Issues
If moisture is seeping from the subfloor, it may be necessary to install a moisture barrier, especially if your laminate is installed over concrete. Moisture barriers can help prevent moisture from rising into the laminate, reducing the risk of damage.
4. Fix Any Leaks or Spills Promptly
Water leaks or spills should be cleaned up immediately. Check for any plumbing issues, as undetected leaks can lead to significant damage over time.
Testing laminate flooring for moisture is a crucial part of maintaining a safe and healthy environment for your floor. With a moisture meter or a simple plastic sheet test, you can quickly identify problem areas and take steps to reduce moisture levels if necessary. By keeping moisture in check, you’ll help your laminate floor last longer and stay in excellent condition, free from warping, buckling, or mould growth.

Excess moisture can cause warping, buckling, swelling, and even mould growth if not addressed.
A moisture meter provides the most accurate results, but a plastic sheet test can be used as a DIY alternative.
Yes, a dehumidifier can control indoor humidity, helping to prevent moisture build-up in laminate flooring.
Regular moisture testing, proper ventilation, and using a moisture barrier during installation are key steps.
No, steam mops introduce excess moisture and heat, which can damage laminate flooring.
High humidity can cause laminate to absorb moisture, leading to expansion, warping, and lifting.
While not as precise as a moisture meter, a plastic sheet test can indicate potential moisture issues.
Use a dehumidifier, improve ventilation, and inspect for any leaks or moisture seeping from the subfloor.
