Can Mould Grow Under Vinyl Plank Flooring? What UK Homeowners Need to Know

With vinyl plank flooring rising in popularity in UK homes and commercial spaces, its range of designs and budget-friendly prices have also raised common concerns about durability, lifespan, and, most importantly, safety when installed in the home without the risk of mould growth. This blog will explain whether mould can grow under vinyl plank flooring and how to prevent it. 

Understanding Vinyl Plank Flooring 

Vinyl plank flooring is durable, man-made flooring known for its waterproofing and scratch resistance. It also offers many other life-like design options for numerous homeowners who want the look and feel of luxury at a fraction of the price. When installed properly, vinyl planks can serve up to 20 years with minimal maintenance needs, such as regular vacuuming and light mopping.

Can Mould Grow Under Vinyl Plank Flooring?

Whereas vinyl plank flooring is said to be waterproof and can withstand water and other spills for a certain period of time, it is not flood-proof. It may be prone to mould manifestations under specific conditions. If flooding goes on for an extended period of time, standing water can seep through the seam systems and damage the glue and subfloor. In the event of flooding, the trapped moisture and absence of airflow offer ideal conditions for mould growth beneath the floorboards.

Common Causes of Mould Under Vinyl Flooring in the UK

It is worth noting that flooding can cause mould growth under the flooring, but there can be various reasons for mould growth under vinyl flooring. These reasons may include a moist subfloor since it provides moisture for mould growth, poor insulation against moisture, as well as condensation resulting from temperature variations that cause humidity, and a damp environment. Although all these reasons are different from one another, it is the moisture that forms a link, as it is the factor that initiates mould growth.

Signs of Mould Growth Beneath Vinyl Planks

It must be noted that it is of the utmost importance when working with vinyl plank flooring that any sign of the development of mould is noted, as the sooner the issue is recognised, the higher the chances of solving the issue with the most efficient means of treating the mould growth. There are several things to note when considering the growth of vinyl plank flooring, including the appearance of a damp odour in the room where it has been installed and unforeseen discolouration of the flooring planks.

Risks of Ignoring Hidden Mould

The mould, if not removed, will proliferate the entire region by dispersing its spores into the air, which can stick to any object, such as the walls or ceiling. Breathing in the mould spores can lead to various health complications, especially for individuals already suffering from health complications. The spores from the mould have the ability to irritate the lungs, causing coughing, sneezing, and discomfort in the neck, as well as rashes on the skin and itchy eyes in the case of an allergic reaction to the spores.

There are certain moulds, such as Stachybotrys chartarum, which are more likely to grow under damp conditions and produce mycotoxins that can lead to health issues, including problems with the brain, immune system, and liver. When these mycotoxins affect a person, they can lead to health problems, including chronic fatigue, headaches, dizziness, and weakened brain function.

How to Prevent Mould Under Vinyl Plank Flooring

Preventing mould underneath your vinyl plank flooring is a process of preparing the right subfloor in advance and making sure that it is dry prior to plank installation. This keeps mould from forming over time because of dampened subfloors.

Using the appropriate moisture barriers and underlayment also ensures that any extra moisture resulting from seasonal temperature changes does not reach your flooring. Quick action related to leaks and spills, indoor ventilation, and humidity control all go toward reducing the occurrence of mould.

What to Do If You Suspect Mould

Once you are sure of the existence of mould under your vinyl plank flooring, it becomes necessary to get rid of as much mould as possible using appropriate tools, such as a scraper. The next course of action is to get rid of as much mould as still exists on the flooring. One of the best options for this purpose is to use a high-intensity vacuum, along with carefully sanding the surface to smooth out any uneven textures. Finally, an anti-fungal treatment may be applied to kill mould that may still be alive and prevent it from regrowing.

In conclusion, mould growth may be an issue during the installation of vinyl plank floors, especially if conditions are right for mould and spore growth. This can, however, be contained if the conditions are properly managed through appropriate planning, installation, moisture control, and frequent maintenance of the floors and the subfloors.
