How to fix water leak under vinyl

Water can flow or seep in under the vinyl plank flooring. Depending on how bad the water leakage is you might need to remove some pieces or the entire floor installation.

Vinyl floors are usually installed above a vapor barrier or a pad. So you will have water trapped under the barrier or pad and you need to remove it.

Because of the vapor barrier, the water cannot dry and if left as it is will eventually lead to molds, a musky smell, and stinks and can make your living area full of microbes.

If there is too much water trapped under the floor you can easily identify it. Usually, the vinyl under those areas will have dents.

And to remove the water you need to use dehumidifiers to suck the moisture out of the floor and dry the floor. You can also use a velocity fan or machines that can pull water out of the floor. 

Make sure to address any underlying issues that caused the leak in the first place such as plumbing problems or faulty appliances. With proper care and attention, you can prevent future leaks from occurring in your vinyl flooring!

Call the restoration workers to restore and perform the installation and uninstallation process without causing any damage to your floor.

Find the source of water leakage 

The first and foremost step in addressing water leakage is finding the source. If the water leakage is due to external factors like flood, damage to certain machines, or leaking from the top you need to make sure to stop the external leakage.

However, if the leakage is because of internal damage under the tile or concrete you need to make sure to resolve the root cause of the problem like sealing the concrete or tile that causes the leakage.

Remember to locate the source of the leak before attempting any repairs. Hire a professional plumber if necessary to fix any leaking & plumbing issues that may be causing the leak.

Identify the spots

Sometimes the entire floor can get wet and water can get trapped everywhere. In that case, the entire structure has to be replaced to suck the water out and dry.

On the other hand, if the water is trapped only in a certain spot, identify the spot and uninstall the flooring only on that particular area and make sure to dry the spot out and reinstall the flooring.

Once you have identified and fixed the underlying issue, carefully remove your vinyl flooring in order to dry out any moisture underneath.

Replace damaged tiles or planks as needed, then reinstall your flooring once everything is dry and secure.

Be sure also to waterproof areas prone to spills or moisture like bathrooms and kitchens.

Tips for preventing water leaks under your vinyl flooring

Prevention is always better than cure, and this holds true for water leaks under your vinyl flooring as well.

Here are some tips to help you prevent such leaks from occurring in the first place.

  • Ensure that all plumbing fixtures and appliances that could potentially cause a leak are properly installed and regularly maintained. This includes checking pipes, faucets, toilets, washing machines, and dishwashers for any signs of wear or damage.
  • Invest in high-quality vinyl flooring that has been specifically designed to resist moisture. Such flooring options come with protective layers that repel moisture and make it easier to clean up spills before they seep through the material.
  • Avoid placing heavy objects or furniture directly on top of your vinyl flooring as this can cause undue stress and eventually lead to cracks or tears which will make it more vulnerable to leakage issues down the line.

By following these simple steps you can significantly reduce the risk of having a water leak under your vinyl flooring while also prolonging its lifespan.


In summary, a water leak under vinyl flooring can be a frustrating experience for any homeowner.

However, with the right knowledge and tools, it’s possible to fix the problem quickly and easily.

By following these simple steps and taking preventative measures against future leaks, you’ll ensure your home stays free from costly damage caused by unwanted water damage beneath your beautiful vinyl floors!
