The Role of the Damp Proofing Surveyor

30th April 2018

Categories  Damp/Surveys


Damp Proofing Surveyors play a vital part in safeguarding properties against the damage from damp and excess condensation. If you’ve ever wondered what the role of a Damp Proofing Surveyor entails, read on for a comprehensive breakdown of the tasks and responsibilities that are normally handled by these highly skilled professionals, and why a damp and timber survey maybe the action you require to get your damp problem sorted.

Diagnosing the damp problem

Any Damp Proofing Surveyor worth his salt will have the objective of getting to the source of the problem.  They do this by building a moisture profile of the property using a combination of methods:

  • Internal and external inspection. This involves noting the condition of ground levels, service penetrations, window and door sealants, gutters, down pipes and roofs, and looking for plumbing leaks, spoiled paint, mould growth, poor ventilation and signs of rot and insect attacks that could indicate the onset of damp. A good sense of smell, photos and sketches are important to this process.
  • Use a range of equipment to help them complete their analysis, including non-destructive moisture profiling tools and thermal imaging cameras.
  • In some cases, they may also take direct samples from the property that can be investigated further.

The treatment that needs to be applied to the property will be governed by the results from the damp survey inspection, combining the results with their expert knowledge to determine a) if treatment is required at all, and b) which type of treatment will best suit the needs of the property.

Treatment will only be recommended once the Damp Proofing Surveyor is confident in their diagnosis.

Finding the right damp treatment

When exploring different remedial options, the damp proofing surveyor will consider the solution they eventually choose is either:

  • A good fit for the building materials
  • Sympathetic to the needs of the property
  • Appropriate to the severity, type and source of the problem
  • Able to provide long-term protection

They will explore all of the treatment methods available to them, which typically include:

  • Chemical damp proof course injection
  • The removal of contaminated plaster
  • Re-plastering and damp proof rendering
  • Application of masonry protection, eg Stormdry
  • Installation of condensation control units
  • Application of anti-condensation and anti-black mould paints, eg Thermokote
  • Repairing structural defects
  • If repair and dry out is the best option such as repair to a leaking roof

Where necessary, the Damp Proofing Surveyor may decide to employ below ground solutions. For Example, if water is entering the property through a wall which has no protection against moisture ingress. Treatment may include a cementitious tanking (a specialist waterproof plaster application), a cavity drainage system, involving the installation of wall and floor membranes, and where water is more excessive, or a property is at risk of flooding, the installation of sump and pump systems.

The individual will assess the needs of the property on a case-by-case basis and using experienced damp proofing contractors, they may choose to employ just one method of treatment or a combination of treatments to achieve the best possible results.

Qualifications and experience

Throughout the entire treatment process, the Damp Proofing Surveyor will need to ensure that the work of all Damp Proofing Contractors and Operatives, recommendations, methods and products used all comply with industry relevant codes of practice.

For example, remedial treatments for rising damp will need to be carried out in accordance with set British Standard guidelines as well as qualifications of the surveyor himself. The letters CSSW and CSRT are key indicators of training and technical ability
