How to Remove Mold from Carpet

Mold in carpets is a serious issue that can lead to health problems and property damage if left untreated. Whether caused by water leaks, high humidity, or improper cleaning, mold growth can spread quickly. This guide will walk you through the safest and most effective ways to remove mold from carpets and prevent it from returning.

Signs of Mold in Carpet

Mold is not always visible, so it’s important to recognize the signs of its presence:

Musty Odor – A persistent, unpleasant smell is often the first indicator of mold. This odor is caused by microbial volatile organic compounds (MVOCs) released as mold grows.
Discoloration – Green, black, or white spots on the carpet may indicate mold growth. These patches often appear in areas exposed to moisture, such as near windows, basements, or bathrooms.
Increased Allergy Symptoms – Sneezing, coughing, skin irritation, and respiratory issues can be signs of mold exposure, especially if symptoms worsen when indoors.

If you notice any of these signs, it’s time to take action.

Wear Protective Gear

Before handling mold, wear gloves, a mask, and safety goggles to protect yourself from inhaling spores. Mold exposure can trigger allergic reactions, asthma, and respiratory issues, so proper protection is essential. Here are some recommended products:
