Mould Removalfor Landlords & Rental Properties
Professional removal and treatment of black mould and other fungal growth
Quick answer
Mould removal (also called mould remediation, or mould control for the ongoing-prevention side of the work) is the professional removal and treatment of mould growth in a property. It involves identifying the mould type, removing affected materials or applying biocidal treatments, addressing the underlying moisture cause, and applying protective coatings. For landlords, it is the primary service for meeting Awaab's Law obligations.
Most mould is condensation. Remediation treats the growth; fixing the ventilation, heating or insulation that caused it is what stops it returning. See condensation control →

Mould in a rented property is not just a cosmetic problem — it is a health hazard and, under Awaab's Law, a legal liability. Black mould (Stachybotrys) and other fungal growth can cause respiratory illness, allergic reactions, and in severe cases, life-threatening complications in vulnerable occupants. Landlords have a legal duty to address mould hazards, and Awaab's Law now sets strict timeframes for doing so.
What Should You Expect?
A professional mould remediation visit will typically include an initial inspection to identify mould type and extent, a written scope of works, removal or treatment of affected surfaces, application of fungicidal coatings or encapsulants, and a post-treatment report. Reputable contractors will also identify the moisture source — without addressing the cause, mould will return.
Mould Removal& Awaab’s Law
Awaab's Law requires landlords to investigate significant mould hazards within 10 working days of a report (24 hours for emergencies) and complete safety works within 5 working days of the investigation concluding. Having a qualified mould remediation specialist on call is essential for meeting these timeframes. MouldPros lists only verified contractors who understand landlord compliance requirements.

Frequently Asked Questions About Mould Removal
- How do I know if I need mould remediation or just cleaning?
- Surface mould covering less than one square metre on non-porous surfaces (tiles, glass) can often be cleaned with appropriate biocidal products. Mould covering larger areas, appearing on porous surfaces (plaster, wood, fabric), or recurring after cleaning requires professional remediation to identify and treat the underlying cause.
- Does mould remediation fix the cause of the mould?
- A good mould remediation contractor will identify the moisture source and recommend how to address it. The remediation itself treats existing growth — but if the underlying cause (condensation, rising damp, penetrating damp, or a plumbing leak) is not fixed, mould will return.
- How long does mould remediation take?
- For a typical residential property, surface mould treatment can be completed in a day. Extensive mould requiring removal of plasterboard, timber, or flooring will take longer — typically 2–5 days. Your contractor should give you a timeline in their written scope of works.
- Is mould remediation enough to satisfy Awaab's Law?
- Remediation addresses the immediate hazard, which is the primary Awaab's Law obligation. However, you should also obtain a written inspection report documenting the investigation, keep records of all works completed, and address the underlying moisture cause — otherwise you risk recurrence and a repeat obligation.
- Can tenants stay in the property during mould remediation?
- Depends on the extent of the work. Surface treatment usually allows tenants to stay. Extensive works involving removal of materials, use of chemical treatments, or significant disruption may require temporary decant. Your contractor will advise based on the specific scope.
