We permanently eliminate dog smell, cat urine, pet dander and animal odours from London properties — using a comprehensive multi-stage process tailored to the type and severity of contamination.
Pet odours — particularly from dog and cat urine — are among the most persistent and chemically complex smells a property can develop. Unlike smoke or cooking odours, pet urine leaves a physical biological deposit that standard cleaning, air fresheners and even basic ozone treatment cannot fully eliminate.
When a pet urinates on a carpet, the liquid immediately soaks through the carpet pile, through the carpet backing, into the underlay and often into the subfloor beneath. As it dries, the water evaporates but the uric acid crystals and organic compounds remain. These crystals are almost impervious to water-based cleaning. When humidity rises — as it does when a property is steam cleaned — they reactivate and release fresh odour molecules.
Cat urine is particularly severe. It contains felinine, a sulphur-bearing compound unique to cats, which continues to break down over time into increasingly pungent substances. A single urine patch left untreated can continue to smell intensely for months or years.
Pet urine contains uric acid crystals — biological compounds that standard cleaning products cannot fully break down. Ozone treatment is highly effective at neutralising odour in the air and on treated surfaces, and it forms an essential part of our process.
However, our experience consistently shows that combining enzyme treatment, ULV fogging and monitored ozone delivers significantly more thorough results than any single method alone. The enzyme stage breaks down biological deposits at the source, fogging penetrates deep into fabrics and backing, and ozone neutralises residual compounds throughout the property.
This staged approach is what allows us to consistently achieve the lasting results our clients expect — particularly for severe urine contamination where multiple layers are affected.
Pet odour — especially urine — cannot be permanently removed by a single treatment. Every job requires a carefully staged process that addresses the biological source before air and surface treatments begin.
Based on our experience with pet-contaminated properties, the best results consistently come from a staged approach. We start with enzyme treatment to address uric acid deposits at the biological level, follow with ULV fogging to penetrate fabrics and air spaces, then apply monitored ozone treatment as a final stage. This comprehensive process addresses every layer of contamination and delivers results that single-method treatments cannot reliably match.
UV light reveals all urine contamination — including hidden patches invisible to the naked eye. We map contaminated areas precisely before recommending the appropriate treatment level.
Professional enzyme-based cleaners are applied directly to contaminated areas. Enzymes biologically break down uric acid crystals — the primary source of pet urine odour — at a molecular level, eliminating what water-based cleaning cannot.
Specialist odour-neutralising solution is applied as a fine mist using a ULV fogger. The mist penetrates deep into carpet backing, soft furnishings, curtains, mattresses and air cavities — reaching areas impossible to treat by hand.
Industrial ozone generators neutralise residual organic compounds in the air and on surfaces. We monitor O₃ concentration in real time throughout. Ionisation provides final air purification, removing remaining particles and odour molecules.
The property is thoroughly ventilated. Safe re-entry conditions are confirmed and aftercare guidance provided to protect results long-term, including advice on preventing re-contamination.
Most ozone operators place a machine and leave. No enzyme treatment, no fogging, no measurement. Our process is fundamentally different — biological and chemical treatment first, then monitored ozone to verify effective concentration is achieved throughout.
We apply professional enzyme-based products to eliminate uric acid crystals before any fogging or ozone — addressing the biological source that other operators ignore.
Our cold-fog equipment delivers specialist neutraliser into carpet backing, soft furnishings and air cavities — reaching contamination in fabrics and deep layers that surface treatment cannot access.
We measure O₃ concentration throughout treatment with professional instruments. You get confirmation that effective levels were reached — not an assumption.
If contamination has reached the subfloor or structural materials, we will tell you before work begins. We never oversell what treatment can achieve.
Every pet odour job follows our full staged process. Our comprehensive staged process consistently delivers the best results for pet urine contamination.

The right approach depends on the type of pet odour, the level of contamination and how deeply biological material has penetrated building materials. We always recommend the most appropriate package honestly.
For light general pet smell — dander, wet dog, or minor odour where no significant urine contamination is present. Suitable only where surfaces have already been thoroughly cleaned and no deep urine deposits remain.
Our most popular package for pet urine odour. Combines enzyme treatment to break down uric acid, ULV fogging with specialist neutraliser, and industrial ozone treatment with real-time monitoring.
Full remediation for heavily contaminated properties. Includes manual surface cleaning with specialist products, deep enzyme application, fogging, ozone treatment and ionisation. Recommended where urine has penetrated to underlay or subfloor level.
Where pet urine has penetrated through carpet into the underlay and subfloor, treatment without removing or sealing the affected flooring may not achieve a complete permanent result. If this is the case, we will advise you clearly before any work begins. In severe cases, flooring replacement may be required as a prerequisite — we will always give you an honest assessment.
In the majority of cases, yes — provided the contamination source is properly addressed at every layer. Our multi-stage process (enzyme treatment, ULV fogging, ozone and ionisation) is designed to eliminate pet odour permanently rather than mask or temporarily reduce it. The key variable is how deeply the biological material has penetrated building materials. We will always give you an honest assessment before work begins.
Our multi-stage approach consistently delivers better and more lasting results than single-method treatments. Enzyme-based products break down the biological source of urine odour at the molecular level, ULV fogging with specialist neutraliser penetrates deep into fabrics and backing, and monitored ozone treatment neutralises residual compounds throughout the property. Addressing contamination at every layer — biological, physical and airborne — is what makes the difference between temporary relief and lasting results.
Cat urine is among the most chemically complex and persistent pet odours, due to the presence of felinine — a sulphur compound that intensifies as it oxidises. We specialise in cat urine odour removal using professional enzyme cleaners, UV inspection to find all contaminated areas (including hidden patches), ULV fogging and monitored ozone treatment. Where urine has penetrated to the subfloor, we will advise you on whether flooring treatment alone is sufficient or whether the underlay needs replacing.
Our experience treating pet-contaminated properties across London has shown consistently that a staged process delivers the best results. Enzyme-based products are specifically formulated to break down the biological components of pet urine — uric acid crystals and organic compounds — at a molecular level. ULV fogging with specialist neutraliser then reaches fabrics, carpet backing and air cavities. Finishing with monitored ozone treatment neutralises residual compounds throughout the property. Each stage targets a different aspect of the contamination, and together they deliver significantly more thorough results.
Yes — landlord and property management work is a significant part of what we do. We regularly treat properties at the end of pet-permitted tenancies, preparing them for viewings, new tenants or sale. We can provide documentation of the treatment carried out for your records. Same-day and next-day appointments are available across London Zones 1–6.
Treatment duration depends on property size and contamination level. The Advanced package for a typical 2-bedroom property generally takes 12–24 hours including enzyme dwell time, fogging and ozone treatment. The Complete package, which includes manual surface cleaning, may require 1–2 days. We will provide a clear timeframe during your free quote.
Cost depends on property size, the number of affected rooms and the severity of contamination. As a guide: Essential treatment from £490, Advanced (enzyme + fogging + ozone) from £695, Complete remediation from £950. Contact us for a free, no-obligation quote based on your specific situation.
Yes, when carried out correctly. All people, pets and plants must leave the treated area during ozone treatment. Once treatment is complete and the property is ventilated, ozone reverts to ordinary oxygen and the space is completely safe to re-enter. We provide clear pre- and post-treatment safety instructions for every job.
Describe your situation — we will give you an honest recommendation and a no-obligation quote. Pet urine severity varies enormously and we will always advise the right approach, not the most expensive one.
