What is a Damp and Mould Survey?

An inspection that finds the cause, not just the symptom

A Damp and Mould Survey is a property inspection designed to investigate moisture-related defects and identify conditions contributing to dampness and mould growth.

A professional assessment helps distinguish between different moisture mechanisms so that appropriate remedial measures can be considered.

Our surveys focus on understanding the property condition, investigating possible moisture sources and providing practical recommendations for improving the indoor environment.

Following the inspection, we provide a structured survey report outlining the findings, potential causes and recommended remedial actions to support informed property maintenance decisions.

Common causes

Damp can develop for several reasons

Penetrating moisture

Plumbing leaks

Condensation

Inadequate ventilation

Defects within the building fabric

Our services

Our Damp and Mould Survey Services

01

Damp investigation

We inspect affected building elements for signs of penetrating damp, suspected rising damp, plumbing leaks and other moisture-related defects. Our assessments help identify potential sources of moisture and the further investigations or repairs required.

02

Mould inspection and assessment

We examine visible mould growth, affected surfaces and surrounding environmental conditions to assess the extent of the problem and identify possible contributing factors.

03

Condensation assessment

Condensation is a common contributor to damp and mould within buildings. We assess factors including internal humidity, surface temperatures, ventilation and heating conditions to investigate the likelihood of surface condensation.

04

Ventilation assessment

Inadequate ventilation can contribute to moisture accumulation. Our surveys consider existing ventilation provisions, including extractor fans, background ventilation and airflow arrangements, to identify potential improvements.

05

Thermal bridging and insulation assessment

Cold surfaces and thermal bridges can increase the likelihood of condensation and mould growth. We investigate potential thermal performance deficiencies and recommend further assessment or suitable improvements where necessary.

06

Damp and Mould Survey report

Following the inspection, a structured report is prepared detailing observations, recorded measurements where applicable, photographic evidence, potential causes and recommended remedial actions.

How we work

Our Damp and Mould Survey Process

  1. Initial consultation

    We gather information about the property, reported damp or mould problems, affected areas and any previous repairs or investigations.

  2. On-site property inspection

    The surveyor inspects accessible affected areas for signs of dampness, mould growth, condensation and potential building defects.

  3. Moisture and environmental assessment

    Where appropriate, moisture readings, relative humidity and temperature measurements are recorded to support the investigation. Additional diagnostic techniques may be recommended depending on the findings.

  4. Identification of potential causes

    The surveyor reviews the available evidence to identify likely moisture mechanisms and determine whether further investigation is required.

  5. Survey report and recommendations

    A written report is prepared, summarising the findings and setting out appropriate recommendations for investigation, repair, moisture management and prevention.

Who it’s for

Spot the signs

Damp and mould: common warning signs

Properties experiencing dampness or mould may display several indicators, including:

  • Black, green or other visible mould patches on walls and ceilings
  • Persistent condensation on windows or cold surfaces
  • Musty or damp odours
  • Peeling wallpaper, blistering paint or damaged plaster
  • Water staining and discolouration
  • Damp patches around windows, external walls or roof junctions
  • Repeated mould growth after cleaning
  • Excessively humid indoor conditions

These signs may have different underlying causes. A professional assessment can help establish what further action is needed.

Landlords and housing providers

Damp and mould assessments for landlords and housing providers

Addressing damp and mould is an important part of maintaining safe, healthy housing.

Quodox Energy Limited provides property inspection and reporting services to help landlords, managing agents and housing providers investigate reported problems, understand potential causes and prioritise appropriate remedial work.

Our assessments can support maintenance planning, record keeping and decisions relating to property condition and the management of damp and mould hazards.

For applicable social housing providers in England, Awaab’s Law introduces statutory requirements relating to the investigation and remediation of specified housing hazards. A professional survey can provide useful evidence within a wider compliance and repair-management process.

Please note

A survey alone does not establish legal compliance or replace a landlord’s obligations to investigate, act within relevant timeframes and complete necessary works.

FAQ

Frequently asked questions

What causes damp and mould in a property?

Damp and mould can result from condensation, inadequate ventilation, water leaks, penetrating moisture, thermal bridging or building fabric defects. In some cases, multiple factors contribute to the problem.

How long does a damp and mould survey take?

The duration depends on the property size, number of affected rooms, accessibility and complexity of the moisture-related issues. The anticipated inspection scope can be discussed when booking.

Will I receive a written report?

Yes. The survey report summarises the inspected areas, relevant observations, potential causes and recommended next steps.

Can a damp and mould survey identify condensation problems?

A survey can assess evidence of condensation and contributing environmental or building conditions. Additional monitoring or investigation may be required for intermittent problems.

Is a damp and mould survey suitable for rental properties?

Yes. Surveys can assist landlords and managing agents in investigating reported damp and mould issues and planning appropriate remedial works.

Does the survey include mould removal?

The survey is an inspection and reporting service. Mould remediation and building repair work are separate activities unless specifically included in an agreed service package.

Can a survey help prevent mould from returning?

A survey can identify likely contributing factors and recommend measures to address them. Long-term prevention depends on properly addressing the underlying causes.
