We permanently eliminate cigarette and tobacco smoke smells from London properties using a comprehensive multi-stage process — specialist surface treatment, ULV fogging and monitored ozone, each addressing a different layer of contamination.
Cigarette and tobacco smoke does not simply linger in the air. It permanently bonds with surfaces. Over time, smoke particles penetrate deep into wall plaster, ceiling paint, carpet fibres, curtain fabric, mattresses, wooden furniture and even the mortar between brickwork.
This process — known as third-hand smoke contamination — means that simply opening windows, repainting walls or using air fresheners will rarely solve the problem. The odour returns because the source remains embedded in building materials.
For landlords, estate agents and homeowners, this creates a serious challenge. A property that smells of cigarettes is harder to let, harder to sell, and may fail tenancy check-out inspections.
Our experience treating smoke-contaminated properties across London consistently shows that a staged approach delivers the most thorough and lasting results. Cigarette smoke leaves a sticky, tar-like residue on all surfaces — and while professional ozone treatment is highly effective, combining it with specialist surface treatment and fogging addresses contamination at every level.
Tobacco smoke leaves a sticky, tar-like residue containing thousands of chemical compounds. This residue needs to be chemically broken down and removed before ozone treatment can reach the odour molecules embedded deeper in building materials. Without this step, ozone will reduce the smell — but will not eliminate it permanently.
In the vast majority of cases we encounter, the property has not been properly prepared. Surfaces may have been vacuumed or wiped down, but the smoke residue coating walls, ceilings, woodwork and soft furnishings remains largely intact. A comprehensive treatment approach is essential for lasting results.
At minimum, all affected hard surfaces should be treated with specialist chemical smoke odour removers before any ozone or fogging treatment. For heavily contaminated properties, this means physically washing walls, ceilings, skirting boards, window frames and woodwork with professional-grade products formulated specifically to break down smoke compounds — not general cleaning agents.
Every smoke odour removal job follows a structured, multi-stage process. The approach is tailored to the severity of contamination and the property type.
Ozone treatment is the final stage — not the only stage. For lasting results against cigarette and tobacco smoke, every job must begin with thorough chemical treatment of contaminated surfaces. Skipping this step is the primary reason smoke smell returns after treatment.
We assess the level of contamination, identify surface buildup, and determine the correct treatment package. We always advise honestly — if the property needs surface cleaning first, we will tell you.
Walls, ceilings, woodwork and hard surfaces are treated with professional smoke odour-removal chemicals. Ideally this is done by hand — physically washing every surface with specialist agents that break down the tar residue at source.
Specialist odour-neutralising solution is applied using a cold fog machine (ULV fogger). The fine mist penetrates soft furnishings, carpets, curtains and air voids that cannot be reached by manual cleaning alone.
Industrial ozone generators are deployed throughout the property. We continuously monitor O₃ concentration in real time to verify effective levels are reached and maintained. Ionisation is applied as a final air-purification stage.
The property is thoroughly ventilated. We confirm safe re-entry conditions and provide aftercare guidance to protect and maintain the results long-term.
Most ozone operators place a machine and leave. They don't clean surfaces first, don't use specialist fogging agents, and don't monitor ozone levels. Our process is fundamentally different — chemical treatment and fogging prepare the property, then ozone is applied and monitored in real time to verify effective concentration is achieved.
We are one of the few operators in London who measure ozone concentration throughout treatment using professional instruments — not guesswork.
Commercial-specification ozone generators — significantly more powerful than consumer units available online — ensuring effective treatment even in heavily contaminated properties.
We do not use fragrances, deodorising sprays or masking agents. The odour is destroyed at the source — ozone breaks down the actual compounds that cause the smell.
We assess every property individually. If smoke contamination is in wall cavities or inaccessible areas, we will tell you before you spend money on treatment.
We don't just run an ozone machine and leave. Every job includes specialist surface treatment and ULV fogging before ozone — because our experience shows this staged approach consistently delivers the best and most lasting results.

The right treatment depends on how heavily the property has been contaminated and whether surfaces have already been professionally cleaned. We offer three levels of treatment for cigarette and tobacco smoke odour.
Suitable for lightly contaminated properties where all surfaces have already been thoroughly cleaned with specialist products. Ozone treatment is the final neutralisation stage only — surfaces must be pre-treated.
Our most popular package. Combines ULV cold fogging with specialist smoke neutraliser followed by industrial ozone treatment with real-time monitoring. Effective for most residential smoke odour cases.
Full remediation for heavily contaminated properties. Includes manual washing of all surfaces with specialist chemicals, ULV fogging, industrial ozone treatment and ionisation. Recommended for long-term heavy smoking or fire-damage cases.
The effectiveness of smoke odour removal depends significantly on whether the underlying source of contamination has been addressed before treatment. Where smoke residue is embedded inside wall cavities, beneath flooring or within insulation, additional remedial works may be required. We provide an honest assessment before any work begins.
Yes. We specialise in cigarette and tobacco smoke odour removal from residential properties across London. Our industrial ozone treatment breaks down smoke compounds at a molecular level rather than masking them. In most cases — where the source contamination has been properly addressed — we achieve excellent results.
Treatment duration depends on the size of the property and the severity of contamination. For an average 2-bedroom flat, the Essential package takes approximately 4–8 hours. The Advanced package typically requires 12–24 hours including fogging and ozone treatment. The Complete package, which includes surface cleaning, may require 1–2 days. We will give you a clear timeframe during your free consultation.
When our full staged treatment is carried out correctly, results are typically excellent and long-lasting. Smoke smell can return in cases where contamination has penetrated deeply into wall cavities, insulation or structural materials that are inaccessible to surface treatment — in these situations, we always advise you honestly before work begins about what to expect. For the vast majority of properties, our comprehensive approach delivers thorough and permanent results.
Yes, when carried out correctly. The property must be unoccupied during treatment — people, pets and plants must leave the treated area. Once treatment is complete and ventilation has been carried out, ozone reverts to ordinary oxygen and the property is completely safe to re-enter. We provide clear pre- and post-treatment instructions.
Absolutely. We work regularly with landlords, letting agents and property management companies across London to prepare smoke-affected properties for new tenancies, valuations and sales. We can provide documentation confirming the treatment was carried out for your records.
Cost depends on property size, the number of rooms affected and the severity of contamination. As a guide: Essential Ozone Treatment from £490, Advanced (ULV + Ozone) from £695, and Complete Remediation from £950. Contact us for a free, no-obligation quote tailored to your specific situation.

Ozone oxidises odour molecules and is highly effective as part of a comprehensive process. However, cigarette smoke leaves a physical residue — a sticky, tar-like deposit — on walls, ceilings, soft furnishings and surfaces. This residue acts as a continuous source of odour molecules. Ozone can neutralise what it reaches, but cannot fully penetrate thick surface contamination.
In our experience, most properties we treat have not been adequately prepared. Surface residue must be broken down chemically — ideally by physically washing all surfaces with specialist smoke-removal agents — before ozone treatment begins. We also use ULV cold fogging with specialist neutraliser to reach soft furnishings and inaccessible areas. Only then does ozone treatment deliver the deep, lasting result clients expect.
Ozone treatment only works when the correct concentration is achieved and maintained. Running an ozone machine without measuring is like baking without a thermometer — you cannot know whether the right conditions were reached. We use professional instruments to monitor O₃ levels in real time, verifying that treatment was effective rather than guessing.
