Damp & Mould Surveys

At Firntec, we work with landlords nationwide to undertake large programmes of damp & mould surveying with the ability to provide a collated summary and action trackers for easy management of remedial action across all properties.

Why you Need to Complete Damp and Mould Surveys

All types of landlords must guarantee that their properties are equipped with necessary measures to minimise dampness and mould. Regular property inspections, prompt resolution of issues, and implementation of consistent maintenance and management schedules are all essential responsibilities for landlords. 

What’s included in Damp & Mould Surveys?

A specialist damp and mould surveyor will carry out the survey to deliver both detailed information, as well as clear and actionable recommendations that can be implemented to remedy any defects as part of the refurbishment of all types of affected buildings.

The assessment looks into how a building’s envelope and internal environments are affected by moisture. The survey will take into account the building materials used, construction methods (including any alterations), as well as the ground and surface drainage of the property.



What Happens During the Survey?

The Surveyor begins inspections by introducing themselves to the occupier and asking about any damp and mould issues that may be present.

The surveyor will inspect all accessible internal walls and chimneys to identify evidence of damp, leaks or condensation that may be present.

The surveyor then checks the property has a sufficient heating system, ventilation, continuity of insulation, and for signs of excessive moisture.

The survey includes an external inspection of the property from ground level for any defect that may contribute to damp issues internally, such as defective rainwater goods or high ground level. 

Inspections are non-invasive, relying on visual observations and testing with an electrical conductivity metre. Additional equipment and techniques such as a thermal imaging camera, borescope, anemometer which is used for testing fan efficiency, and recording of humidity levels. 

Summary of Outputs From your Damp & Mould Survey Report:

  • A list of any relevant external defects.


  • An assessment and interpretation of the survey findings, including the identification of the cause or source of dampness.


  • Specific advice and recommendations for suitable treatments or remedial actions based on the type of property and the identified cause or type of dampness.


  • An estimation of the potential costs associated with the recommended treatments or remedial works.


  • Any additional information that aids in understanding the report, such as photographs, diagrams or floor plans.

Different Types of Damp and Mould

Condensation Damp
Penetrating Damp
Rising Damp
Traumatic Damp

Condensation damp occurs when moisture produced inside the home cools and condenses onto colder parts of the building, such as window frames, corners, and low points on walls behind sofas or wardrobes. This is the most prevalent type of damp.

Penetrating damp refers to water infiltrating the building from outside due to defects in the walls, roofs, windows, or floors.

Rising damp is moisture from the ground that rises up through parts of the buildings in contact with the ground (walls and floors); it is usually found in older properties and is often misdiagnosed. It can be identified through visual inspection; however chemical testing is the most appropriate way of confirming it. Often it is due to defective damp proof courses and membranes.

Traumatic damp can be caused by leaking water from waste and heating pipes, overflowing baths or sinks, burst pipes or defective water storage vessels inside the building. Traumatic damp can also originate from outside the property, for example from another building or from environmental flooding.

Mould is a type of fungus which grows in moist environments. Mould can cause adverse health effects as well as damage to buildings.
