Is the training behind the 7-Step Survey Method City & Guilds Assured?

Selected courses are. The 7-Step Survey Method is taught through the FODCS surveyor certification, which is independently City & Guilds Assured and CPD certified, and the FODCT technician certification is also City & Guilds Assured. So a surveyor certified in this method earns an externally quality-assured credential rather than a self-issued one.

The Federation of Damp Standard

The 7-Step Survey Method for diagnosing damp

Q: Why does the order of the steps matter?

Most misdiagnosis comes from jumping to a conclusion. The method requires inspection and testing before diagnosis, and diagnosis before any recommendation, so treatment is never proposed without understanding the true cause first.

Q: How does the method help with condensation and mould?

The ventilation and environmental assessment step evaluates airflow, humidity, heating and occupancy, which distinguishes condensation, frequently misdiagnosed as rising or penetrating damp, so the correct solution is recommended.

Q: Do all Federation of Damp members follow this method?

Yes. The 7-Step Survey Method is the foundation of Federation of Damp training and certification, and every member agrees to follow it. Members trained in the method can be found on the register.

The Federation of Damp has developed a structured, evidence-based approach to diagnosing damp and moisture problems. The FOD 7-Step Survey Method™ is followed by every certified member, so damp is identified on evidence, not assumption.

The problem we exist to fix

Why most damp surveys go wrong

Across the industry, damp is frequently misdiagnosed. The same avoidable mistakes appear again and again.

Over-reliance on moisture meter readings

Misdiagnosing condensation as rising damp

Failure to inspect external defects

Recommending treatment before proper investigation

Which leads to Incorrect work carried out Ongoing damp problems Unnecessary cost for owners

The principle behind the method

Inspect, test, diagnose, then recommend

The method combines inspection, testing and environmental assessment to reach a clear, evidence-based conclusion before any work is proposed.

Recommend

A treatment should never be recommended without a proper diagnosis first.

Step by step

The 7-Step Survey Method™

A structured, repeatable process. Each step builds a complete understanding of the property, so all relevant factors are considered before a diagnosis is made.

Inspect

Client brief & property background

The survey begins by gathering the client's concerns, the history and duration of the problem, any previous treatments or repairs, and how the property is occupied and used. This context guides the survey. A proper diagnosis cannot be made without first understanding the background.

External inspection

A comprehensive external inspection identifies building defects that may be allowing moisture in: ground levels, damp proof course height, brickwork, pointing, render, roofing elements and rainwater goods. Many damp problems originate outside, so this comes before internal symptoms are assessed.

Internal visual inspection

The internal inspection identifies visible signs of damp and moisture damage: staining, tide marks, mould growth, salt contamination, blown plaster and timber defects. These observations show how the damp presents and give valuable clues to its underlying cause.

Test

Moisture testing

Moisture testing supports the visual findings and maps moisture patterns within walls and materials, with readings taken at different heights and locations. Meters must be used correctly and in context. They support the diagnosis, they do not determine it in isolation.

Ventilation & environmental assessment

The surveyor assesses the internal environment to see whether ventilation, heating and occupancy are contributing to the problem, evaluating airflow, humidity, extractor fans and cold bridging. This step is key to identifying condensation, which is often misdiagnosed.

Diagnose

Diagnosis

All information gathered is reviewed to determine the most likely cause, weighing building defects, environmental conditions, moisture patterns and construction type. The diagnosis must be logical, evidence-based and supported by the findings from every previous step.

Recommend

Recommendations & reporting

The final stage produces a clear, structured report setting out the findings, diagnosis and recommended actions. Recommendations must be proportionate to the issue and based on the evidence gathered, with the reasoning behind the diagnosis clearly explained.

One standard, applied consistently

Common questions

About the 7-Step Survey Method

What is the Federation of Damp 7-Step Survey Method?

It is a structured, evidence-based process for diagnosing damp and moisture problems in buildings. It moves through seven stages, from client brief and inspection to testing, diagnosis and reporting, so that a conclusion is reached on evidence rather than assumption. Every certified Federation of Damp member is trained to follow it.

Why does the order of the steps matter?

Because most misdiagnosis comes from skipping straight to a conclusion. The method requires inspection and testing before any diagnosis, and a diagnosis before any recommendation, so treatment is never proposed without understanding the true cause first.

Why are moisture meter readings not enough on their own?

Moisture meter readings can be influenced by several factors and are easily misread out of context. In the 7-Step Method they support a diagnosis alongside visual inspection and environmental assessment, but they never determine it in isolation.

How does the method help with condensation and mould?

The ventilation and environmental assessment step specifically evaluates airflow, humidity, heating and occupancy. This is what distinguishes condensation, which is frequently misdiagnosed as rising or penetrating damp, so the right solution is recommended.

Is the training behind the method City & Guilds Assured?

Selected courses are. The 7-Step Survey Method is taught through our FODCS surveyor certification, which is independently City & Guilds Assured and CPD certified, and our FODCT technician certification is also City & Guilds Assured. City & Guilds is the UK's leading skills certification organisation, so a surveyor certified in this method earns an externally quality-assured credential, not a self-issued one.

Do all Federation of Damp members follow this method?

Yes. The 7-Step Survey Method is the foundation of our training and certification, and every member agrees to follow it. You can find members trained in the method on our register.
