Can Mold Grow Under Vinyl Plank Flooring? The Answer May Surprise You.

Are you considering a vinyl plank flooring installation? This type of flooring is becoming an increasingly popular choice due to its modern and stylish look, durability, and affordability. However, when selecting this type of flooring, many people need to consider the potential for mold growth. 

In this blog post, we will discuss the factors that can contribute to mold growth under vinyl plank flooring and some tips for avoiding it. 

What Is Vinyl Plank Flooring?

Vinyl plank flooring is a popular type of flooring made from synthetic materials, such as polyvinyl chloride (PVC), that are designed to resemble traditional hardwood floors. It’s becoming a popular choice for homeowners looking for an affordable and low-maintenance option. Vinyl plank flooring is also moisture-resistant, making it an excellent choice for humid areas.

Can Mold Grow Under Vinyl Plank Flooring?

The short answer is yes. Under the right conditions, mold can find its way into even the most unlikely places, including under vinyl plank flooring. The primary risk factor for mold growth is moisture. 

If excess water is present in the area where your flooring is installed, it can seep through the seams and joints in the planks and into the subfloor. 

Also, suppose your subfloor isn’t completely dry before installing your flooring. In that case, this, too, can lead to moisture buildup, which can promote mold growth.

Common Causes of Mold Growth Under Vinyl Plank Flooring

High Humidity Levels in the Home

When humidity levels in your home are too high, it can create a moist and damp environment ideal for mold growth.

Poor Ventilation

Ventilation is essential for removing moisture from the air, and inadequate ventilation can lead to excess humidity, promoting mold growth.

Standing Water on the Subfloor or Planks

Any standing water on the subfloor or planks can lead to mold growth.

Plumbing Leaks or Flooding

If your home has experienced a plumbing leak or flooding, this can lead to excess moisture and encourage mold growth.

7 Tips to Prevent Mold Growth

There are a few easy steps you can take to prevent mold growth under your vinyl plank flooring:

Maintain Proper Ventilation

Ensure the area is completely dry before installing your flooring. If the subfloor has not properly dried, it can be a breeding ground for mold.

Properly Seal Floors

Use a sealant to close any gaps between the planks. This will help to keep moisture from seeping in and prevent mold growth.

Monitor Humidity Levels

Consider installing a dehumidifier in your home to reduce humidity levels, which can also help to prevent mold growth.

Monitor Spills and Signs of Water Damage

Check your flooring regularly for signs of water damage or moisture, as this could indicate a problem with your installation that needs to be addressed.

Keep Up With Cleaning

Have your flooring professionally cleaned regularly to remove any dust or dirt that may be present. This will help to keep the area dry and reduce the risk of mold growth.

Install Vapor Barriers and Moisture Proof Subfloor Materials

If you’re worried about moisture seeping into your subfloor, consider installing a vapor barrier and using moisture-proof subfloor materials. This will help to prevent water from impacting the integrity of your flooring in the future.

Invest in Quality Vinyl Plank Flooring

When selecting your vinyl plank flooring, opt for a quality product that is designed to be moisture-resistant.
