Landlords: Damp & Mould Problems Properly Investigated
Damp and mould complaints from tenants need clear, credible investigation.
An independent damp assessment identifies the real cause of moisture problems and provides evidence that the issue is being properly addressed.
This helps landlords protect their property, communicate clearly with tenants, and avoid unnecessary or ineffective treatments.

Damp & Mould Investigations for Landlords
Stay Compliant, Protect Your Property & Avoid Unnecessary Costs
Landlords are under increasing pressure to deal with damp and mould concerns properly.
With the introduction of Awaab’s Law under the Social Housing Regulation Act 2023, expectations across the housing sector have changed. Even where the legislation directly applies to social housing, the standards are influencing what tenants, agents and local authorities now expect from landlords.
In simple terms, when damp or mould is reported it should be:
• taken seriously
• properly investigated
• supported by clear evidence of what was found
An independent damp assessment provides that clarity.
Why Proper Diagnosis Matters
Many landlords are encouraged to try quick “solutions” such as mould washes, fogging treatments or damp-proofing injections.
These approaches often treat the symptoms rather than the cause.
In many cases damp or mould is linked to issues such as:
• ventilation behaviour
• cold surfaces and thermal bridging
• moisture trapped in poorly ventilated areas
• small leaks or minor building defects
Understanding the true cause helps avoid unnecessary and costly treatments.
How Thomas Damp Surveys Helps
I provide independent, evidence-based damp investigations designed to give landlords clear answers.
My surveys help landlords to:
• demonstrate that damp or mould complaints have been properly investigated
• understand the true source of moisture or mould growth
• communicate clearly with tenants about what has been found
• avoid unnecessary damp-proofing or ineffective treatments
• receive practical, common-sense guidance on next steps
There are no products sold and no sales agenda — just an honest diagnosis focused on solving the problem.
Independent Advice You Can Rely On
If a situation requires a specialist contractor or further investigation, I will say so honestly and point you in the right direction.
If you are a landlord dealing with damp or mould concerns and want clear answers and practical advice, get in touch to discuss an inspection.
When Tenants Report Damp or Mould
Damp and mould complaints are one of the most common issues raised by tenants in rental properties.
When a problem like the one shown on the left appears — mould around windows, cold surfaces or poorly ventilated areas — it can quickly lead to concern for both tenants and landlords.
The key question is always the same: what is actually causing the problem?
When mould is reported, landlords need to show that the issue has been taken seriously and properly investigated.
Without a proper assessment it is easy to jump straight to treatments such as mould washes, fogging or repainting.
These often deal with the visible mould but not the underlying cause, meaning the problem returns.
Most mould growth is linked to factors such as:
• moisture produced inside the property
• limited ventilation or airflow
• cold surfaces where condensation forms
• localised leaks or small building defects
Identifying the true source of moisture is the first step toward resolving the issue properly.
Independent Damp Investigation
My role is to carry out an independent damp and moisture assessment to understand what is contributing to the problem.
During the inspection I look at:
• ventilation levels within the property
• temperature differences across surfaces
• areas where moisture may accumulate
• possible leaks or building defects
• how the construction of the building affects moisture movement
Moisture meter readings and observations are interpreted alongside the building construction to identify the most likely causes of damp or mould growth.
Clear Evidence for Landlords and Tenants
Following the inspection you receive a clear explanation of:
• what was observed
• the likely causes of damp or mould
• practical steps that may help resolve the issue
This provides independent evidence that the problem has been properly assessed, helping landlords communicate clearly with tenants and avoid unnecessary or ineffective treatments.
Practical, Honest Advice
Sometimes the solution is straightforward.
Sometimes further work or specialist repair may be required.
If a situation requires a contractor or additional investigation, I will say so honestly and point you in the right direction.
My role is not to apportion blame, but to identify the most likely causes of moisture or mould so the issue can be addressed sensibly.
