Mold growth under wet carpet is a serious issue that can compromise your home’s air quality, cause health problems, and damage your flooring. Whether due to an unexpected spill, a plumbing leak, or flooding, moisture trapped beneath your carpet creates the perfect environment for mold to thrive.
Preventing mold growth under wet carpets not only preserves the appearance and lifespan of your flooring but also helps avoid potential health risks and costly repairs down the road.
In this blog, we will explore common causes of wet carpets and effective steps to prevent mold under the wet carpet, so that you can keep your carpets safe from mold damage.
Common Causes Of Wet Carpet
Before we learn how to prevent mold under wet carpets, let’s first discuss common causes behind wet carpets.
- Leaky Pipes: Plumbing leaks or burst pipes are one of the most frequent causes of wet carpets, especially in areas near bathrooms or kitchens.
- Flooding: Heavy rainstorms, floods, or natural disasters can cause water to enter homes, leading to soaked carpets.
- Roof Leaks: Water can drip through damaged roofs or ceilings and end up on carpets, especially after rainfall.
- Appliance Malfunctions: Washing machines, dishwashers, refrigerators, or water heaters can malfunction or overflow, leading to a wet carpet near the appliance.
- Condensation: High humidity levels or poor ventilation can lead to condensation buildup, particularly around windows and walls, eventually making the nearby carpet damp.
- Overflowing Toilets or Sinks: Clogged toilets or sinks can cause water to overflow and spread to adjacent carpeted areas.
- Foundation Issues: Poor foundation drainage can allow water to seep into basements, causing carpets in those areas to become wet.
- AC Unit Leaks: Improperly maintained air conditioning units may leak water, which can saturate the carpet near the unit.
- Pet Accidents: Pet urine or spilled water from pet bowls can leave carpets wet if not cleaned promptly.
- Improper Carpet Cleaning: Overwetting the carpet during steam cleaning or not allowing it to dry properly afterward can leave carpets damp.
Preventing Mold Under Wet Carpet In 4 Easy Steps
One of the many reasons why cleaning the carpet is essential to prevent allergies and other health problems (especially after water damage) is that mold exposure can lead to various health issues, especially for individuals with respiratory issues, allergies, or weakened immune systems.
Common symptoms include coughing and sneezing, wheezing and difficulty breathing, nasal congestion, stuffiness, eye irritation, headaches, and skin rashes. Henceforth, let’s understand how to prevent mold growth under a wet carpet in four simple steps.
1. Locate The Source Of The Water
To prevent mold under the wet carpet, the first step is to locate the source of the water damage. Identifying the source of water is essential to prevent further water damage.
That said, once you know where the leak is coming from, you can take steps to stop it. This might involve turning off water valves, calling a plumber, or making temporary repairs.
Knowing the source of the leak can also help you determine the extent of the water damage. This information is crucial for deciding whether you need professional help or if you can handle the situation yourself.
In addition, move furniture away from the wet area so that you can easily clean and dry the carpet. Besides, if the water level is high, use a wet/dry vacuum cleaner (or rent one from your nearby hardware store) to extract the standing water.
2. Remove The Carpet Padding
The next step is to remove the carpet padding. Carpet padding is a porous material that can absorb and retain moisture. Even after removing standing water and addressing the source of the leak, moisture can remain trapped in the padding.
This, in turn, creates an ideal environment for mold growth, which can lead to further damage. Thus, take a utility knife, and start cutting the carpet into manageable sections. Now, use the pry bar to lift the edges of the padding. Once the edges are lifted, pull the padding up and remove it from the floor.
After removing the padding, inspect the subfloor for any damage caused by the water or mold. If necessary, make repairs to the floor before reinstalling new padding and carpet.
3. Clean And Disinfect The Carpet
The third step is to clean and disinfect the carpet. To do so, you can either choose white vinegar or hydrogen peroxide solution. White vinegar is slightly acidic, which creates an environment that hinders the growth of mold spores. It also disinfects surfaces, preventing mold from spreading on the surface of the carpet.
On the other hand, hydrogen peroxide is a powerful oxidizer that breaks down mold spores on contact. It penetrates deep into the carpet fibers, where mold can settle, killing the spores before they grow into colonies.
White Vinegar
If you are using vinegar, mix one tablespoon of white vinegar with two cups of water in a spray bottle. Spray the solution onto the damp carpet, focusing on areas with the most moisture or where mold is likely to develop.
Allow the vinegar solution to sit for 15-20 minutes, as this gives it ample time to kill mold spores and bacteria. After that, rinse and use a clean towel or cloth to blot the carpet dry after spraying. This removes excess liquid and reduces the drying time.
Hydrogen Peroxide
In a spray bottle, mix one tablespoon of 3% hydrogen peroxide with two cups of water. Now, before applying, test it on a small, hidden area of the carpet to make sure it won’t bleach the fibers.
If all seems good, spray the solution onto the carpet, particularly in areas where mold might form or where stains from water damage are visible. Allow it to sit for 10–15 minutes. Once the wait is over, rinse and blot the carpet dry using clean towels to remove excess hydrogen peroxide.
4. Dry The Carpet Thoroughly
As you’ve applied the solution, allow your carpet to dry completely. To effectivize the process, place table fans near the carpeted area or turn on your dehumidifiers. If possible, lift the carpet to allow air to circulate under it. This helps dry out both the carpet and the subfloor, reducing mold risk.
The final step is to inspect the carpet for one final time and replace the old padding with new, moisture-resistant padding. After that, reinstall the carpet and stretch it properly to ensure it lies flat without any signs of wrinkles or bubbles.
When You Should Call A Professional?
If the carpet is heavily soaked or there’s a significant amount of water under the padding or subfloor, it can be difficult to clean the carpet and dry it completely on your own. In such cases, you might want to consider calling a professional to prevent mold under the wet carpet.
Professional carpet cleaners, such as Beverly Hills Carpet Cleaners, are highly experienced individuals with 20 years of experience in the carpet cleaning industry.
They use powerful deep cleaning methods, such as steam cleaning with top-notch tools and solutions, to extract water and eliminate bacteria, mold spores, and other harmful organisms in the vulnerable, sanitizing both the carpet and the padding. This ensures that your carpeted floors stay clean and healthy for the good.
