THE CARPET IS GONE. THE URINE SMELL ISN’T. HERE’S WHY.
When pet urine penetrates through carpet and underlay, the damage doesn’t necessarily stop there.
It can soak deep into the subfloor, leaving behind urine contamination that continues to cause unpleasant odours, even after the carpet has been completely removed.
And here’s something many homeowners don’t realise: humidity can reactivate residual urine odours, making them noticeable again long after the original damage occurred.
So how do we tackle the problem?
This is Antonio Lewis, co-owner of Chem-Dry Metro, applying a specialised sealing membrane to a subfloor following extensive pet urine contamination.
But this isn’t where the process started.
A week earlier, the urine-damaged carpet had been removed and the exposed subfloor professionally treated to address the contamination.
Once the treatment had been given sufficient time to work and the subfloor was ready, Antonio returned to apply the final protective barrier.
Why is sealing so important?
Even after professional decontamination, residues can remain deep within porous subfloor materials.
During periods of high humidity, moisture can encourage residual contaminants to migrate towards the surface, potentially allowing unpleasant odours to return.
Our specialised sealing membrane creates a protective barrier designed to minimise this migration and help prevent residual odours from affecting the new flooring above.
It’s about more than removing the smell today. It’s about reducing the risk of it returning tomorrow.
At Chem-Dry Metro, we specialise in complex pet urine contamination and odour problems that go well beyond ordinary carpet cleaning.
Whether you’re renovating, replacing urine-damaged flooring, preparing a rental property or dealing with persistent pet odours, identifying and treating the underlying source is critical.
