Mold Under Ceramic Tile Floors

Is your bathroom or kitchen tiled? Have you peeled back some of the tile and noticed dark staining underneath on the sub flooring? The dark staining you see is quite possibly mold and it will need to be addressed right away.

If left untreated, mold will begin to break down the organic surface that it is growing on. This article will discuss how you can identify mold under bathroom floor, how you can treat it and how you can prevent it from coming back. We also discuss the possible health risks and repercussions of not treating and removing mold in your home right away.

What Causes Mold to Grow Under Ceramic Tiles

The tile flooring in your bathroom or kitchen is regularly exposed to moisture, the subfloor is usually wood, and the tile provides shade and warmer temperatures. The perfect storm for mold to flourish.

Mold in your bathrooms is seen most commonly in homes with tile flooring. You run your shower or bathtub daily, wet towels are left lying around and there is always the possibility of a leaky pipe. All of these factors will contribute to moisture being allowed to seep under your tiles and stay there.

If there is dampness present under your tiles, there is a very high probability that mold spores will begin to colonize and grow. The mold spores will happily feed off of the organic surface in that area, which is usually wood.

Steam from running your shower is usually one of the biggest culprits for allowing moisture to settle into your flooring. If your bathroom is not properly ventilated during the showering or bathing process, the hot air and steam has nowhere to go except to settle into what’s around the room.

The same applies to the kitchen, or any other room that may be tiled in your home. Any unchecked exposure to moisture in your home can lead to a mold infestation.

What Kind of Mold Grows Under Tile

As we mentioned previously, there are over 1,000 different mold strands and variations so there can be more than one type that can grow under your tiles. The most common mold that you will see under tile in your bathroom is black mold.

Black mold, or Stachybotrys, is a potentially toxic mold strand. This mold is usually identifiable by its dark black color. Some areas of black mold may appear darker than others and there can be a spotted look with lighter and darker areas.

Exposure to the toxic strains of black mold can cause some serious health conditions in humans and pets.

What the Health Risks Associated with Mold Under Tile

Exposure to mold poses many health risks to both humans and pets in your home. The most common side effect to black mold exposure is respiratory responses. This can include; chronic coughing, sneezing, irritation of the eyes, and irritation to the mucus membranes in the nose. One can also experience chronic headaches, fatigue, and skin irritations such as a rash.

Some cases of extreme exposure to black mold can cause nausea, vomiting, nose bleeds and even bleeding inside the lungs. These are very serious side effects and should be avoided at all costs.

There are several factors that can contribute to whether or not a person will have a reaction to mold exposure and if so what that reaction looks like. Some people can be exposed to mold and not ever know it, while others will develop a severe allergic reaction and require treatment.

Individuals who have a medical or respiratory condition such as asthma, COPD or cancer are at a higher risk of developing and experiencing an allergic reaction to mold. Individuals with these conditions already have trouble with the functioning of their respiratory system so exposure to an irritant will make their condition worse.

Infants and young children are also at a higher risk for complications due to mold exposure. Infants, especially premature ones, have immune systems that have not had the chance to properly develop yet, leaving them more susceptible to molds’ nasty side effects.

Elderly individuals are another group of people who may experience more worsened or more pronounced mold exposure symptoms. With old age, our immune systems tend to become weakened and have a harder time fighting off allergies. Elderly individuals also tend to have weaker bodies due to health conditions they may be experiencing or medications that they are taking.

How to Identify Mold

Discovering mold under tiles in your home is not always easy as it is very well hidden. Often times, the mold infestation is discovered only when a renovation is planned and the tile is ripped up. By then, the mold problem could be quite severe and costly to the homeowner.

One way people are clued into a mold problem is by scent. Have you noticed a strange smell in your bathroom lately that won’t go away? If you are smelly a musty or earthy scent that no amount of cleaning can get rid of, it may be mold.

If you have access to the flooring underneath your tiles, you will want to look for dark staining on the wood below. You may also be able to detect the presence of mold by noticing cracks or folds in your floor.

If mold is left to grow for long enough it will start to break down the flooring, causing it to buckle and bend. In this case, the mold problem has gone unnoticed for too long and a major repair and replacement of your flooring will become your reality.

Another method that can be used to determine if mold is present under your tile floor is to purchase a mold testing kit. These kits can be purchased at most any home retailer and cost between $10-$60 depending on the type of test kit and its quality.

Most mold test kits will be able to accurately determine the presence of mold, what type it is and whether or not it is a toxic variety. This is a fairly cost effective way to determine if mold spores are present.

How to Treat Mold

Your treatment method for mold under your tiles in your bathroom will vary depending on how large the infestation is, whether or not your flooring is compromised and whether or not the mold is toxic and posing a threat to your health.

If you discovered just a small patch of mold growing under your tiles, you may be able to treat and remove the mold yourself. A simple homemade solution of bleach and water will usually do the trick in killing and removing the mold spores. You can also purchase mold removal solutions from your local home or hardware store that are designed to kill and stop mold spore growth.

If you choose to tackle your mold problem yourself, make sure that you are protected by wearing gloves, a respirator and clothing that covers your skin fully. Mold spores can get on your skin and result in a reaction or can use you as a vehicle to spread further.

Be sure that the room where you are removing mold from is properly ventilated with fans, HEPA filters or air purifiers. Also make sure that the room is completely closed off from the rest of your home as you begin to remove the mold.
