A flooded carpet is one of those household problems that arrives fast and leaves a trail of questions behind. Whether it’s a burst pipe, heavy rainfall, or an overflowing washing machine, dealing with soaked carpet is stressful—and often confusing.
The first question most homeowners ask is: Can we save the carpet, or does it have to go?
In this article, we’ll break down what you need to know about cleaning carpets after a flood, how to assess the damage, and when to call in the professionals.
First, Understand the Risk
Not all water damage is created equal. The safety and success of cleaning a flooded carpet depends on several factors, including:
- The source of the water
- How long the carpet stayed wet
- The type of carpet and underlay
- The level of contamination (e.g. clean water vs sewage)
Before attempting any cleaning or repair work, it’s important to understand what kind of water you’re dealing with.
Types of Water Damage
Floodwater is typically classified into three categories:
1. Clean Water
This comes from a burst pipe, hot water cylinder, or rainwater that hasn’t mixed with soil or waste. It’s the least risky and usually safe to clean up within 24–48 hours.
2. Grey Water
From washing machines, dishwashers, or kitchen sinks. It may contain soap residue, grease, or food waste. Cleaning is possible, but sanitisation is essential.
3. Black Water
This includes sewage, stormwater runoff, or water that’s been sitting too long. It’s considered hazardous, and in most cases, carpet exposed to black water should be replaced for health reasons.
Time Is Critical
Mould and bacteria start to grow within 24 to 48 hours of water exposure. The longer your carpet stays wet, the more likely you’ll face permanent damage—not just to the carpet fibres, but to the underlay and subfloor as well.
If your carpet has been soaked for more than two days, even clean water can become a risk factor. At that point, carpet sanitisation becomes just as important as drying.
Signs Your Flooded Carpet Can Be Saved
In some cases, carpet cleaning after a flood is completely possible. Your carpet may be salvageable if:
- The water was clean and recent
- The carpet was professionally dried within 24–48 hours
- The underlay wasn’t fully saturated or can be removed and replaced
- There’s no visible mould growth
- The subfloor hasn’t warped or sustained damage
In these cases, a combination of deep carpet cleaning and sanitisation may restore the carpet fully.
When Your Carpet Needs to Be Replaced
Unfortunately, some flood scenarios are too severe for cleaning alone. You’ll likely need carpet replacement if:
- The water was contaminated (grey or black)
- The carpet and underlay stayed wet for several days
- There’s visible mould, discolouration, or foul odour
- The backing or seams have detached or delaminated
- The subfloor is showing signs of swelling, warping, or decay
It might sound like a worst-case scenario, but replacing carpet early can prevent worse problems down the line—like structural damage or health issues from mould spores. If you want to learn more about carper replacements, you can read our article on when you should replace your carpet.
What About Drying Carpet Yourself?
Many homeowners try to dry carpet using towels, fans, or heaters. While this might help with surface moisture, it’s rarely enough on its own. Moisture can remain trapped in the underlay or backing, creating a perfect environment for bacteria and mould—even if the surface looks dry.
If you do attempt drying before professionals arrive, try this:
- Blot excess water with clean towels (don’t rub)
- Use dehumidifiers to draw out moisture from the air
- Lift corners of the carpet to allow airflow underneath
- Keep windows open if it’s dry outside, or use fans with open doors
But remember: even a carpet that “feels” dry may not be dry all the way through.
