How to identify the smell of water damaged carpet
The smell that suggests water damaged carpet or mould growth on carpet is a musty, damp, or earthy odour. It’s a distinctive, stale smell that can fill a room and linger even after cleaning efforts. This smell is caused by the presence of excess moisture in carpet fibres, which creates an ideal environment for mould to grow and thrive.



As mould develops and grows the water damaged carpet smell intensifies as the mould release spores into the air, which contribute to the pungent, unpleasant odour. The smell can sometimes be compared to wet towels left in a damp bathroom for too long or the scent of an old, wet basement. If the carpet hasn’t been dried properly, the smell may grow stronger over time, and you might also notice a sour or even decaying scent as bacteria begins to proliferate.
If you’re detecting this type of water damage carpet smell, it’s a clear sign that moisture has been trapped in your carpet for an extended period, and that mould growth may be present. The mould may not be visible yet, but if you lift your carpet, you will see it on the underside. If this type of water damage carpet smell is something you have noticed in your home, take immediate action to prevent further damage.
Why you should act fast if you suspect water damage
Water damage doesn’t just create an unbearable smell on your carpet, it also affects the appearance and integrity of your carpet—it can also impact your health. The longer water sits on your carpet, the more likely it is that mould will contaminate it. Mould can cause respiratory issues, allergies, and other health problems, especially for people with asthma or compromised immune systems.
Additionally, if water damage is left untreated, it can spread to the underlying structure of your home. The moisture can seep into the subfloor, walls, or insulation, causing further damage and potentially leading to expensive repairs.
