What it is
What severe mould removal covers.
Severe mould removal is the specialist treatment of mould that has spread beyond a surface issue. Standard end of tenancy cleans handle light surface mould on tile grout, sealant, and windowsills. This page is for the cases where mould has gone deeper: into plaster, behind furniture, across whole walls or ceilings, or wherever it keeps coming back after cleaning.
Black mould (often stachybotrys chartarum) is the most-searched-for category but it isn't the only one that matters. Several mould species can grow in UK properties and they require different treatments. A specialist who identifies the species before treating is doing the work properly.
Mould is almost always a symptom of a moisture problem. Removing the visible mould without finding and fixing the source is a temporary fix. Proper mould remediation includes root-cause assessment so the mould does not return.
When you'd need this
When standard cleaning isn't enough.
Light surface mould on a bathroom sealant or tile grout is a job for a standard end of tenancy clean. The cases below are different and need a specialist.
- Black mould across a whole wall or ceiling, not just a small patch.
- Mould growing on plasterboard, behind furniture, or in cavities.
- Mould that keeps coming back within weeks of cleaning.
- Property after a leak, flood, burst pipe, or condensation problem that was not fully remediated.
- Anywhere a doctor, HSE inspector, environmental health officer, or RICS surveyor has flagged a health concern.
- Properties with vulnerable occupants (children, elderly, immunocompromised, asthmatic) where any mould is a concern.
- Landlord properties where Ombudsman or housing complaints have flagged damp and mould.
The work
What a mould remediation specialist does.
Mould remediation is more involved than cleaning. The specialist works through identification, containment, removal, treatment, and root-cause assessment.
Identification: the specialist looks at the mould (sometimes takes a sample) to determine the species and the extent. This matters because different mould species need different chemistry, and surface-level mould needs a different approach to mould that has gone into the building fabric.
Containment: the affected zone is sealed off (plastic sheeting, taped seams) so spores don't travel through the property during the work. HEPA-filtered air scrubbers run during the work to capture airborne spores at the same time.
Removal: surface mould is cleaned with antifungal chemistry. Mould that has penetrated plaster, plasterboard, sealant, or wood is removed with the affected material. There is no chemical that 'cleans' mould out of saturated plasterboard; the plasterboard has to come out.
Treatment: antifungal treatment is applied to the substrate (the structure under what was removed) so any spores left behind don't regrow. The treatment is a different chemical to the cleaning agent and is left to dry rather than wiped off.
Root-cause assessment: the specialist identifies why the mould grew in the first place. Condensation? Leak? Cold-bridging? Inadequate ventilation? Without fixing the source, the mould will return. The assessment can lead to recommended work (extractor fan upgrade, leak repair, insulation, ventilation review) which may or may not be done by the same team.
- Mould species identification before treatment.
- Containment of the affected zone during the work.
- HEPA-filtered air scrubbing during the work.
- Antifungal treatment of surfaces and substrate.
- Removal of mould-saturated materials (plasterboard, sealant, flooring).
- Root-cause assessment so the mould does not return.
- Documentation for landlord compliance, Ombudsman, or RICS surveyor records.
Process
From your call to mould properly dealt with.
1. You tell us what you are dealing with
Quick form, photos of the affected areas, and any context: how long the mould has been there, what you have tried so far, whether anyone in the property has health concerns. The wizard captures what the specialist needs.
2. We connect you with the right specialist
Mon to Fri 9 to 5 we call within the hour. The lead for severe mould cases is a vetted specialist team that covers the Docklands and travels to the job, who handle mould removal as a core service. Further vetted teams are available as alternates.
3. Site assessment
The specialist visits to identify the species, the extent, and the source of the moisture. The assessment includes a recommendation: pure remediation, or remediation plus source-fix work (extractor fan, leak repair, insulation).
4. Remediation
Containment, removal, antifungal treatment. Typical residential job runs a few days. If material removal (plasterboard, flooring) is needed, it can take a week or more. The specialist provides documentation at the end suitable for landlord compliance or insurance records.
Why come through us
The first quote you get is rarely the right one.
Mould remediation is a category where the difference between specialists matters a lot. A team that only treats the visible mould will leave the source untouched and the mould will be back. A team that does full remediation including root-cause assessment costs more up front but actually solves it.
We've watched the specialists in our network do this work for years. We know which one understands root-cause work versus which one is faster for a surface-level case. The triage matters more here than in some other categories.
If you call a mould specialist directly, you may get a quote for a quick fix that does not address why the mould grew. Coming through us means we brief the specialist on the situation, including any landlord or Ombudsman context, and they arrive prepared.
It costs you nothing. The specialist quotes you directly. We are paid by them after the job.
Pricing
How mould remediation is priced.
Mould remediation pricing depends on the species, the extent (square footage and depth), whether material removal is needed, and whether root-cause work is included. A surface-level treatment on a single wall might be a few hundred pounds. Full remediation with plasterboard removal and source-fix can run into thousands.
Landlord cases sometimes flow through insurance (buildings cover for damp and mould resulting from an insured event like a leak). Health-related cases sometimes flow through Ombudsman-mandated remediation. The specialist will check what funding routes might apply on the call.
We never add a markup. The price the specialist quotes is the price you pay.

Related specialist services
Severe Mould Removal cases often overlap with other specialist work.
Specialist cases rarely fit one category cleanly. If your situation involves more than one of the services below, mention it on the form. We'll match you to a specialist who handles both, or connect you with two partners working together.
- Biohazard cleaning. Severe mould cases sometimes overlap with biohazard contamination, especially where the cause was sewage or a burst soil pipe.
- Cleaning after pest control. Rodent infestations create damp conditions that lead to mould. Both often need treating together.
- Hoarder cleaning. Closed-up hoarded properties commonly develop severe mould. Mould remediation often follows the initial clearance work.
FAQ
Mould Removal FAQs
Common questions about severe mould removal in Canary Wharf.
Is black mould dangerous?
Severe black mould exposure can affect respiratory health, especially for asthmatics, children, elderly, and immunocompromised people. NHS guidance recommends removing mould rather than living with it. If a doctor or HSE has flagged a concern, treat the case as priority.
Why does my mould keep coming back?
Almost always because the source of the moisture hasn't been fixed. Condensation, leaks, cold-bridging, inadequate ventilation, broken extractor fans, and lapsed damp-proofing are common causes. A specialist who does not assess the source is treating a symptom.
Can you treat mould without removing the plasterboard?
Sometimes, if the mould is still surface-level. Once it has penetrated the plasterboard or sealant, the material has to come out. There is no chemical treatment that pulls mould out of saturated plasterboard. The specialist will tell you on the assessment which case you have.
What about the rest of the property? Will the mould spread during the work?
Not if the work is done properly. The specialist contains the affected zone with sheeting and runs HEPA-filtered air scrubbing during the work to capture spores. Done badly, mould remediation can spread spores through the property. Done properly, it does not.
I'm a tenant and my landlord won't act. What can I do?
Document the mould with photos and dates. Write to the landlord (or letting agent) requesting action. If they don't respond, you can escalate to the Housing Ombudsman (social housing) or to Environmental Health at your local council. Severe mould is a Category 1 hazard under the Housing Health and Safety Rating System and councils can serve enforcement notices on landlords who refuse to act.
I'm a landlord. What's my exposure on mould complaints?
Under the Homes (Fitness for Human Habitation) Act 2018 and the Landlord and Tenant Act 1985, landlords are responsible for keeping properties free of damp and mould caused by structural or maintenance issues. The Ombudsman has been increasingly assertive on damp-and-mould complaints since 2022. A documented professional remediation is the cleanest defence against a complaint.
Does treatment include preventing the mould from returning?
Treatment by itself does not. Root-cause work does. A proper mould job includes identifying why the moisture is there and recommending (or doing) the source-fix work: extractor fan upgrade, leak repair, insulation, ventilation review. The specialist will agree the scope with you on the assessment.
