Damp, Mould & Leak Investigations for Landlords
When a tenant reports damp or mould, you need one thing fast: to know what’s actually causing it, and a report that proves you acted. Our investigation team attends across London & Surrey, confirms the cause, and gives you documentation that stands up to a tenant, a council, or the Housing Ombudsman.

The law changed and it’s still changing
Since 27 October 2025, Awaab’s Law binds social landlords to fixed statutory timescales for damp and mould: emergency hazards made safe within 24 hours, and significant hazards like damp and mould investigated within 10 working days, with a written summary to the tenant within 3 working days of the investigation. The Renters’ Rights Act 2025 is extending equivalent duties across the private rented sector, so whether you let one flat or a portfolio, “we’ll get to it eventually” is no longer a defence.

The single most useful thing you can hold when a complaint lands is an independent investigation report that says what the cause is and what was done. That is exactly what we produce.
What we do for landlords
- On-site investigation: our engineers attend, measure, and confirm the cause (not a guess).
- Cause attribution: the report that settles the argument: is it tenant lifestyle/condensation, or a structural fault or leak that’s your responsibility to fix? We say so, with evidence.
- Treatment + repair quoted separately (mould treatment, leak repair, ventilation) through our team or your own contractor, so the report stays independent.
- Dispute & deposit evidence: dated, instrument-backed documentation for tenancy disputes or deposit deductions.
The report you receive
Written to be read by a council environmental health officer or an ombudsman caseworker: cause and location; moisture readings and thermal evidence; condensation-vs-structural attribution; photographs; the works we recommend and why. This is the record that shows you investigated properly and on time.
How working with us runs
One point of contact, honest quotes before any work, and portfolio rates if you let more than a handful of units. We cover London & Surrey and can attend at short notice.
Landlord FAQ
Does Awaab’s Law apply to me as a private landlord? It binds social landlords now. The Renters’ Rights Act 2025 is extending equivalent damp-and-mould duties to the private rented sector. The direction is clear, and an independent report protects you either way.
Can you tell whether it’s the tenant’s lifestyle or my building? Yes. That attribution is the core of our report. We distinguish condensation from leaks and structural defects with instrument evidence.
How soon can you attend? Call 0800 054 1524 for the earliest available appointment across London & Surrey; urgent cases are prioritised.
Do you fix it too, or just report? We investigate and report. Treatment and repairs are quoted separately, through our team or a contractor of your choice, so the diagnosis stays independent.
Do you offer portfolio rates? Yes. Tell us how many units and we’ll set up terms.
