Pet urine can penetrate the carpet fibre, the backing and the underlay beneath. When contamination reaches the underlay, surface cleaning alone usually will not remove the odour because the source remains. Professional treatment locates the contamination with UV inspection, treats each affected layer and neutralises the odour compounds rather than masking them. Book an assessment so the extent of contamination can be confirmed before treatment is recommended.
Quick Answer
Pet urine can penetrate the carpet fibre, the backing and the underlay beneath. When contamination reaches the underlay, surface cleaning alone usually will not remove the odour because the source remains. Professional treatment locates the contamination with UV inspection, treats each affected layer and neutralises the odour compounds rather than masking them. Book an assessment so the extent of contamination can be confirmed before treatment is recommended.
Pets urinate on carpet for many reasons — marking, anxiety, illness or incomplete house-training. Urine passes through the pile into the backing and underlay, and sometimes into the subfloor. As it dries, uric acid crystals form and reactivate with moisture, which is why the smell often returns on humid days.
Yes, in most cases. Success depends on how far contamination has spread, how old it is, and whether the underlay or subfloor is involved. Light surface contamination can often be fully resolved; deep contamination may require underlay replacement or subfloor sealing.
A persistent urine smell, visible yellow staining, dark patches under UV light, a pet returning to the same spot, or odour that worsens in humid weather.
Off-the-shelf sprays and steam cleaning can dilute urine and spread it over a wider area, driving contamination deeper and making odour worse. Professional treatment uses targeted extraction and neutralising chemistry applied only to the contaminated zones.
We inspect with a UV light to locate active and old contamination, assess the carpet, backing and underlay, and check for subfloor involvement before recommending a treatment plan.
Most odour is significantly reduced or eliminated when every contaminated layer is treated. Where underlay or subfloor is saturated, replacing the underlay and sealing the subfloor gives the most reliable result. We do not guarantee complete odour removal where contamination has spread beyond the carpet.
A typical treatment takes 1–3 hours depending on the number and size of contaminated areas. Drying takes 2–6 hours.
Cost depends on the area affected, the number of contamination sites, and whether underlay replacement or subfloor sealing is required. We provide a fixed quote after inspection.
If urine has saturated the underlay or subfloor over a wide area, replacing the underlay and treating or sealing the subfloor is usually more effective than repeated surface cleaning.
UV inspection to locate all contamination sites
Extract loose soil and surface moisture
Apply neutralising treatment to contaminated zones
Flush and extract through to the backing
Treat or replace underlay where required
Apply odour-neutralising rinse and speed-dry

Yes, old urine can often be treated, but dried uric acid crystals are stubborn. Success depends on whether contamination has reached the underlay or subfloor.
Uric acid crystals reactivate with moisture. If the source in the underlay or subfloor was not treated, humidity or cleaning moisture can bring the odour back.
Yes. Urine soaks through to the underlay and can permanently contaminate it. Heavily saturated underlay usually needs replacing.
We use a UV light and moisture detection to find contamination that is not visible on the surface.
Not always. Many carpets can be saved. Replacement is usually only needed when contamination is widespread through the underlay and subfloor.
Dog Urine Removal
Dog urine is usually deposited in larger volumes than cat urine and soaks quickly through the carpet pile into the backing and underlay. Because the contamination often reaches the underlay, surface cleaning alone frequently fails to remove the odour. Professional treatment locates each deposit with UV inspection, neutralises the uric acid and treats or replaces affected underlay. An assessment determines how deep the contamination goes before treatment is recommended.

Carpet odours come from different sources — pet urine, smoke, mould, food, spills trapped in the backing, or moisture. Masking with fragrance does not remove the cause. Professional odour removal identifies the source, treats the affected layers and neutralises the odour compounds. Where the source is in the underlay or subfloor, that layer must be treated or replaced for a lasting result.
Read moreCarpet Stain Removal
Carpet stains differ widely — tannin stains (wine, coffee), protein stains (blood, dairy), oil-based stains, dye stains and chemical stains each need a different chemistry. The wrong treatment can set a stain permanently or damage the fibre. Professional stain removal identifies the stain type and the carpet fibre first, then applies the correct chemistry. Some permanent dye damage or bleaching cannot be reversed, so an honest assessment comes before treatment.
Read morePet Urine in Rugs
Rugs are often more delicate than wall-to-wall carpet and many are sensitive to moisture and chemistry — especially wool and natural-fibre rugs with unstable dyes. Pet urine can pass through to the backing and floor beneath. Professional rug urine treatment inspects the fibre and dye stability first, then uses a controlled process to neutralise the uric acid and flush the contamination. Some rugs require off-site immersion cleaning for a reliable result.
Read moreLounge Stain Removal
Lounge fabrics vary widely — synthetic, cotton, linen, microfibre and blends — and each needs different chemistry. The wrong treatment can set a stain, cause browning or damage the fabric. Professional lounge stain removal identifies the fabric and stain type first, tests for colourfastness, then applies the correct treatment. Some dye damage or bleaching is permanent and cannot be reversed.
