We help landlords and estate agents across London eliminate all types of inherited tenant smell — from tobacco and pets to cooking, mould and general habitation odour — using a tailored multi-stage treatment based on what the property actually needs.
When a tenancy ends, what a previous occupant leaves behind is often not just wear and tear — it is months or years of embedded odour. Smell is one of the most powerful factors influencing a prospective tenant's first impression of a property. Research consistently shows that odour is the single most common reason a prospective tenant or buyer forms a negative impression during a viewing.
Unlike visible dirt or cosmetic damage, embedded odour cannot simply be cleaned away. It has penetrated wall paint, carpet fibres, curtains, soft furnishings and building materials. It is invisible but immediately detectable — and it signals neglect to any viewer, even if the property is otherwise immaculate.
For London landlords with monthly rents often exceeding £2,000, a property sitting vacant for even two extra weeks due to odour represents a significant financial loss — one that typically far outweighs the cost of professional treatment.
Previous tenant odour is rarely a single smell. A typical tenancy of two or more years can leave a layered combination of odours — each requiring different treatment approaches, different chemical agents and different techniques to fully address. The right treatment must be matched to what the property actually contains.
| Odour Type | Common Source | Difficulty |
|---|---|---|
| 🚬 Smoke & cigarette | Indoor smoking throughout tenancy | High |
| 🐕 Pet & urine | Dogs, cats or uncleaned accidents | Very high |
| 🍳 Strong cooking | Curry, fish, frying over years | High |
| 🎃 Mould & damp | Condensation, poor ventilation | Moderate |
| 💨 General habitation | Long occupation, poor ventilation | Moderate |
| 👺 Vape / e-cigarette | Indoor vaping residue | Moderate |
| 🐀 Rodent residue | Infestation, post-pest-control | Specialist |
The right treatment for inherited tenant smell depends entirely on what the property contains. We always begin with a thorough assessment before recommending anything — then apply the appropriate combination of treatments for the specific odours present.
Previous tenant odour is rarely a single smell — it is a combination of accumulated odours each requiring the right treatment agent. We assess what is present, recommend the most effective and cost-efficient approach, and apply a staged treatment: specialist surface treatment appropriate to the odour types identified, followed by ULV fogging and monitored ozone. The result is a property that genuinely smells fresh and neutral.
We assess the property systematically, identifying all odour types present, the areas most affected, and the treatment approach best suited to each. We provide an honest recommendation and transparent quote before any work begins.
The appropriate specialist chemicals are applied to contaminated surfaces based on the odour types present — degreasers for cooking, anti-mould biocides for damp, enzyme cleaners for pet urine, smoke-specific agents for tobacco. One size does not fit all.
Specialist odour-neutralising solution is applied throughout the property as a fine mist, penetrating curtains, carpets, soft furnishings, wall cavities and ceiling spaces — reaching embedded compounds that surface treatment alone cannot address.
Industrial ozone generators neutralise residual airborne compounds throughout the entire property simultaneously. We monitor O₃ concentration in real time throughout. Ionisation provides final air purification. The property smells genuinely neutral when complete.
The property is ventilated and ready for viewings. We provide documentation of the treatment carried out on request — useful for landlord records, agent files and deposit dispute evidence where relevant.
Many operators apply a standard treatment regardless of what is actually in the property. Our process starts with identifying what odours are present and matching the treatment to the specific compounds involved. Every job then finishes with monitored ozone to verify effective treatment throughout.
We identify what is actually present before recommending anything. Different odour types require different chemical agents — applying the wrong treatment wastes money and delivers poor results.
From tobacco smoke and pet urine to curry smell, mould and vape residue — we handle the full range of inherited tenant odours in a single visit where possible, saving you time and coordination effort.
Every job finishes with industrial ozone treatment and real-time O₃ monitoring. You get confirmation that effective levels were achieved — not an assumption. Properties are genuinely odour-free when we leave.
We provide written documentation of the treatment carried out on request. Useful for landlord records, managing agent files and evidencing remediation steps in deposit or inspection disputes.
We understand that vacant properties cost money. Same-day and next-day appointments are available across all London Zones, and most treatments are completed within 24 hours of starting.

The right package depends on what types of odour are present and how severely contaminated the property is. We assess every property individually and recommend the most cost-effective approach to get it viewings-ready.
For properties with mild or single-type odour where surfaces have already been cleaned. Suitable for general habitation odour, light cooking smell or mild mould odour in a well-maintained property.
Our most popular end-of-tenancy package. Includes targeted surface treatment matched to the odour types present (smoke, pet, cooking or mould), full ULV fogging throughout and industrial monitored ozone. Covers most standard tenancy odour situations.
Full remediation for heavily contaminated properties — long tenancies, multiple odour types, heavy smoking, pets and cooking combined, or where contamination has penetrated deeply into building materials. Includes manual cleaning, full targeted treatment, fogging and ozone.
Tell us about the property and the tenancy history — we will recommend the right package based on what is actually there. We never upsell treatments that are not needed, and we will always advise honestly if there are aspects of the contamination that may require additional remedial work alongside odour treatment.
In most cases, yes. Our assessment identifies the combination of odours present, and we bring the appropriate chemical agents and equipment to address all of them in a single visit where possible. Properties with multiple severe odour types — such as heavy smoking combined with cat urine and mould — may require the Complete package, which allows time for each stage to work effectively. We will always advise honestly on the most realistic outcome.
Same-day and next-day appointments are available across all London Zones. We understand that vacant properties represent lost income and we prioritise fast turnaround for landlord and agent clients. Most Advanced package treatments are completed within 24 hours of starting, leaving the property ready for viewings the following day.
A basic clean helps but is not always essential before we begin. For our Advanced package, we can work with a property that has been cleared of belongings but not yet professionally cleaned. Our Complete package includes manual surface cleaning as part of the service. If the property still has the previous tenant's belongings inside, treatment cannot begin until it has been cleared — we will advise on this during the assessment.
Yes. We can provide written confirmation of the treatment carried out, the areas treated and the methods used. This is useful for landlord records, managing agent files and — where relevant — evidencing remediation steps taken in deposit disputes or check-out inspection follow-ups. Documentation is available for all packages on request.
This is very common. Our assessment identifies the odour types present — you do not need to know in advance. We will inspect the property, identify what is there and recommend the most appropriate and cost-effective treatment. If you have a strong smell but are unsure of the source, call us and describe what you notice — we can often advise on the likely cause before visiting.
The goal of our treatment is to achieve a genuinely neutral-smelling property — not to replace one smell with another. We do not use masking fragrances or perfumed sprays. Ozone treatment is odourless once the property is ventilated, and the specialist fogging agents we use are formulated to neutralise rather than mask. When treatment is complete and ventilation is carried out, the property should smell fresh and neutral — the way a new tenant expects it to.
Cost depends on property size, the number of odour types present and the severity of contamination. As a guide: Essential from £390, Advanced from £595, Complete remediation from £850. Properties with multiple severe odour types may require the Complete package.
