A complete six-stage remediation service: we dry the space, remove mould, treat surfaces with matched specialist products, apply cold fog, run ozone and finish with plasma ionisation. Every stage in the right order — not just a machine left in a room.
Most odour removal companies arrive with an ozone generator and leave. We don't. Our service is a structured, multi-stage remediation process — each stage preparing the way for the next, so the final result lasts.
We start by drying the space if damp is present. We then remove mould physically and treat contaminated surfaces with professional-grade specialist products matched to the specific source — smoke, pet urine, mould, grease or another contaminant. Only once the environment is properly prepared do we move to cold fogging with a specialist neutraliser, followed by ozone treatment, and finally plasma ionisation for deep air purification.
Each stage does something the others cannot. Together, they address the problem completely — at the source, in the air, and on every surface.
One of the most stubborn odour problems in London rental properties. Smoke compounds penetrate deep into walls and ceilings. Our multi-stage ozone treatment reaches where cleaning cannot.
Pet urine and dander are persistent because the compounds bond to soft surfaces. We combine surface treatment with ozone to neutralise both the smell and the organic residue causing it.
Musty, damp odours indicate mould spores in the environment. We treat visible mould, apply specialist primers that prevent regrowth, and use ozone to address airborne spores throughout the space.
Accumulated cooking odours in kitchens and open-plan spaces. We treat ventilation areas, surfaces and the air — particularly effective ahead of a sale or new tenancy.
When a property has housed tenants for years, odours accumulate. Our treatment is ideal for landlords turning around between lets, restoring a genuinely neutral baseline.
New paint, adhesives, sealants and renovation dust create indoor air quality issues. Ozone treatment accelerates off-gassing and restores clean air — particularly important for new purchases.
Drainage smells that have permeated into a property. We identify the likely source and treat the affected areas, working alongside plumbers where the structural cause needs addressing first.
Post-fire smoke odour is one of the most challenging remediation problems. We work as part of a broader restoration approach — treatment is most effective once fire damage has been structurally addressed.
Cold ULV fogging delivers specialist odour-neutralising agents as microscopic droplets that penetrate deep into soft furnishings, ventilation ducts and cavities unreachable by surface cleaning. The agent is selected specifically for the contaminant.
Ozone (O₃) is one of the most powerful oxidation agents used in professional remediation worldwide. When released in a controlled environment, ozone molecules react with odour compounds, bacteria and mould spores — breaking them down at a molecular level. Once treatment is complete, ozone naturally reverts to ordinary oxygen (O₂), leaving no chemical residue.
Plasma ionisation provides the final deep air purification stage. Plasma charges airborne particles and remaining pollutants, destabilising and clearing them from the air. Combined with ozone, it delivers a level of air quality restoration that either technology achieves alone.
We identify the odour source, severity, moisture levels and property layout. We look for active damp, hidden mould and structural issues that need addressing before treatment begins. You receive an honest, fixed-price quote within 48 hours.
Pre-visitIf the space has elevated moisture — from a leak, flooding, condensation or active damp — we dry it first using industrial dehumidifiers and air movers. Treating a wet environment is ineffective. Drying is the essential foundation for everything that follows.
Stage oneVisible mould is removed manually using specialist products. Contaminated surfaces — walls, ceilings, woodwork, grout — are cleaned with professional-grade treatments matched specifically to the contaminant: anti-mould agents, enzymatic cleaners for biological sources, or degreasing compounds for cooking residue. The right product for the right problem.
Stage twoWe apply a specialist neutralising agent as a cold ULV fog, which penetrates soft furnishings, ventilation systems and cavities that conventional cleaning cannot reach. The fog is matched to the specific odour source — smoke, pets, mould or organic contamination — and begins breaking down odour compounds that remain after surface cleaning.
Stage threeWith the environment properly prepared, professional ozone generators are positioned throughout the property. Ozone (O₃) circulates through every room, surface and hidden space, oxidising remaining odour molecules, bacteria and airborne contaminants at a molecular level. We measure ozone concentration throughout using a professional instrument — verifying effective levels are reached, not assumed.
Stage fourFinally, plasma ionisation charges and destabilises any remaining airborne particles — providing a deep final air purification stage that ozone alone cannot deliver. The space is then ventilated, ozone levels are monitored, and we confirm the property is safe and ready for re-entry. For most residential treatments, you return the same evening.
Stage five + handoverMost companies place an ozone generator in a room and leave it running for a fixed period. Without measuring, they have no way of knowing whether effective treatment levels were actually achieved. If ozone concentration is too low, odours may only be partially treated and return within days.
We use professional ozone concentration meters throughout every treatment. This verifies that the required level has been reached in every room, allows us to adjust equipment positioning for maximum effectiveness, and gives you transparent confirmation — not guesswork. You receive a property that has been properly treated, not one that has simply been exposed to a running machine.
Combined with the preceding stages — drying, surface remediation and cold fogging — measured ozone treatment ensures the process is genuinely complete rather than partially effective.
Because ozone is highly active during treatment, the property must be vacant while the process is underway. We will provide full preparation instructions before every appointment — but here is what to expect.
Must leave the property during treatment:
Important: The success of any odour removal treatment depends largely on eliminating the underlying source. If active damp, an unresolved leak, contaminated subfloor or ongoing mould growth is present, we will advise on what structural work is needed first. We give honest, realistic expectations — not assurances we cannot back up.
We will confirm all preparation steps in writing before your appointment. There is nothing complicated — but following the instructions carefully makes the treatment as effective as possible.
For most standard residential properties, you will be able to re-enter the same evening. Larger properties, commercial spaces or severe contamination may require additional time or repeat visits — which we will discuss honestly during assessment.
Yes — when carried out correctly in a vacant property. People, pets and plants must leave the treated area during the process. Once treatment and ventilation are complete and ozone levels have been measured and confirmed safe, the property can be re-entered. We confirm safe re-entry time before leaving.
Because our service is a complete multi-stage process — drying, surface remediation, cold fogging, ozone and plasma — rather than ozone alone, a single visit resolves the majority of cases when the underlying source has been addressed. For severe long-term contamination, active mould from an ongoing leak, or heavy smoking built up over many years, we may recommend repeat treatment or structural remediation first. We will tell you honestly what to expect during the assessment, before any booking is made.
Because effectiveness depends on concentration. Running a generator without measuring is like cooking without a thermometer — you have no confirmation the required level has been reached. We measure throughout, adjust equipment positioning if needed, and provide you with clear evidence that treatment has been properly carried out. Most companies simply do not do this.
We can address surface mould, mould-related odour, and airborne mould spores. However, if mould is caused by an active water ingress, condensation problem or structural damp, those underlying issues must be resolved first — otherwise the mould (and the smell) will return. We identify this during the initial assessment and will be direct about what is needed.
Yes. We treat residential homes, rental properties, offices, serviced apartments, hotels and other commercial spaces across Greater London. Larger or more complex sites may require a tailored approach — contact us to discuss your specific situation.
We respond fast, give honest assessments and provide effective treatment — not just reassurance.
