The Importance of Following; BRE 245, BS 6576, and BS 5250 for Damp and Timber Surveys

Before we dive into the nitty-gritty of a Damp and Timber Survey, it's crucial to understand the importance of adhering to industry standards. Building Research Establishment (BRE) 245, British Standard (BS) 6576, and BS 5250 are the cornerstones of best practices in the field of building preservation and damp management. (If the survey doesn't follow these British Standards and other relevant guidance then is worthless, and will cost you a lot of money due to misdiagnosis).

BRE 245: This standard offers guidelines for the assessment of the moisture levels in buildings. It outlines methods for identifying and managing dampness issues effectively.

BS 6576: Focusing on the diagnosis of dampness in buildings, BS 6576 provides comprehensive guidance for surveyors. It covers everything from initial inspections to the interpretation of findings.

BS 5250: This British Standard deals with the control of condensation in buildings. It sets out the requirements for ventilation, thermal insulation, and building design to prevent condensation-related issues.


Your surveyor should be independant and never carry out the work, this is direct conflict of interest. Some companies do the survey and tell you it needs all this work and it costs this much. Usually specifying a new damp proof course, chemical injected DPC and other solutions. Which are rarely required. "A cheap survey, can cost you a fortune".


Damp and Timber Survey Methodologies: Non-Intrusive vs. Intrusive

A Damp and Timber Survey typically follows two primary methodologies: non-intrusive and intrusive.

Non-Intrusive Survey

This initial phase involves a thorough visual inspection of your property, both inside and out. The surveyor assesses various factors, including the condition of walls, floors, ceilings, and the presence of damp stains or mold. Non-intrusive surveys can provide valuable insights, but they may not always uncover hidden issues. This is covered within our RICS Homebuyer report (Level 2 Survey) and the RICS Building Survey (Level 3) if you are buying a property more about: Which Level of survey or Commercial Surveys.

Intrusive Survey

When non-intrusive methods yield inconclusive results or if deeper investigation is necessary, an intrusive survey is the next step. This approach involves physically accessing concealed areas of the property, such as wall cavities, to uncover the root causes of damp and timber problems. It provides a more conclusive understanding of the issues at hand. Includes localised drilling of walls (Small 10mm holes), removal of sections skirting/floor boards and small sections of plaster, where required as part of the investigation. Chemical testing and sampling is carried out in line with the above standards.

If a company offers to conduct a Damp and Timber survey and investigation it should follow these two methods, the second being more conclusive.

The Role of Chemical Testing and Sampling

To pinpoint the exact cause of dampness, chemical testing and sampling play a pivotal role. This scientific approach involves collecting samples of materials like timber, masonry, or plaster and subjecting them to laboratory analysis. By assessing moisture content, Chloride and Nitrate levels, and other key factors, surveyors can determine the underlying issues causing dampness and decay.

The Duration of a Damp and Timber Survey

The duration of a Damp and Timber Survey can vary depending on the size and complexity of the property and the issue. On average, it typically takes between 2 to 5 hours for the on-site inspection. However, the process doesn't end there. Surveyors invest several hours afterward to compile their findings, analyze the data, and produce a comprehensive report.
