What Is a Damp and Mould Disrepair Claim?

What is a damp disrepair claim?

A damp disrepair claim is a legal action brought by a tenant against a landlord who has not repaired damp, mould or the underlying defects causing them within a reasonable time. It sits under the landlord’s repairing obligations, which cover the structure and exterior of the property and installations such as pipes, drains and guttering. When a leak, penetrating damp or rising damp is left unaddressed and the home becomes unfit to live in, the tenant may be entitled to have the work done and, in many cases, to compensation.

The claim is not about mould on its own. It is about the cause behind the mould and whether the landlord had a duty to fix it, was told about it, and failed to act. That is why the diagnosis of the source matters as much as the damage itself.

What are the signs my home is in disrepair?

Disrepair usually shows up as visible damp and mould combined with a defect the landlord is responsible for. The common signs include:

• Black or green mould spreading across walls, ceilings or around windows.
• Damp patches, tide marks or staining that return after being painted over.
• Peeling wallpaper, blistering paint or crumbling plaster.
• A persistent musty smell that does not clear with ventilation.
• Water ingress after rain, or damp tracking down from a roof, gutter or upstairs.
• Rot in skirting, window frames or floorboards.
• Health effects such as worsening coughs, wheezing or respiratory irritation.

How do I know if I have a valid claim?

You are likely to have a valid claim if the disrepair falls within the landlord’s responsibility, they knew about it, and they failed to fix it in a reasonable time. Work through this self-check:

1. Confirm the cause sits with the landlord, such as a structural defect, a leak, or failed guttering, rather than a condition you can resolve yourself.
2. Check that you reported the problem, ideally in writing, so there is a record of the date the landlord was put on notice.
3. Note how long the landlord had to act and whether the work was carried out.
4. Gather evidence: dated photos, messages, and any medical notes if your health has been affected.
5. Arrange a Damp, Mould and Water Damage Assessment so the cause is diagnosed and recorded in a written report a court or solicitor can rely on.

The single most important piece is the evidence that identifies the cause. Without it, a landlord can argue the damp is down to lifestyle or condensation, and the claim stalls. A clear root-cause diagnosis removes that argument.

What does Awaab’s Law mean for landlords?

Awaab’s Law sets strict timeframes for landlords to investigate and fix damp and mould once a hazard is reported. It was introduced after the death of Awaab Ishak, who died from exposure to mould in his home, and it requires social landlords to act within fixed deadlines rather than leaving hazards unresolved. Alongside it, the Renters’ Rights Act strengthens tenants’ ability to hold landlords to account and to challenge properties that are not kept in a fit state.

For tenants, this means the law increasingly expects fast action and proper investigation, not repainting over the problem. For landlords, it raises the standard of proof they need that a hazard has been properly diagnosed and addressed. In both cases, a written survey that maps the moisture and names the cause is the document that shows whether the duty has been met.

When should I call in a specialist?

Call in a specialist as soon as damp or mould keeps returning, or the moment you need evidence that will stand up in a disrepair claim. A proper investigation starts with full moisture mapping across the affected area to measure where the water is and how far it has spread. We then use thermal imaging and non-destructive, non-invasive leak detection, including acoustic and tracer methods, to trace the source before anything is opened up. Only once the cause is confirmed do we set out what needs to happen, so the diagnosis comes before any remedial work is agreed.

We diagnose the cause; we do not sell remedial work, so the report tells you what is actually wrong rather than steering you toward a job. We confirm the price on a written quote once we understand the problem. Our Damp, Mould and Water Damage Assessment (what many people call a damp survey) includes full moisture mapping, root-cause diagnosis and a written, insurance-ready report with a photographic evidence appendix, clear findings and prioritised recommendations, which is exactly the kind of evidence a disrepair claim relies on. If a leak needs tracing to its exact source, we quote for leak detection separately.

To get an initial view, call us on 020 3051 8478 or send photos via WhatsApp and we will tell you what we are looking at and what the next step should be.

If you've got damp, mould, or a leak, you already know it needs sorting.

The longer it sits, the worse it gets. Get in touch and we will agree a date with you. If it is urgent, say so when you call.
