Independent Damp Survey – Honest Diagnosis Without the Sales Pitch
An independent damp survey focuses on identifying the true cause of damp problems, not selling unnecessary treatments. At Dampline, our surveys are carried out with diagnosis first, giving you clear, professional advice you can trust.
Our independent surveys form part of our full damp survey service, designed to identify the real cause before any work is recommended.
What Is an Independent Damp Survey?
An independent damp survey is a professional inspection designed to determine the cause of damp issues within a property without automatically recommending damp proofing work.
The aim is to understand what is happening, why it is happening, and whether any remedial work is actually required.
Unlike surveys linked directly to treatment sales, our independent approach prioritises accuracy, transparency, and long-term solutions.
​
Why Independence Matters
Many damp surveys are carried out by companies that also sell damp proofing treatments. This can sometimes lead to unnecessary or incorrect recommendations, particularly in older or solid-wall properties. Many damp surveys are carried out by companies that also install treatments such as rising damp systems, condensation control measures, or penetrating damp repairs. While not always intentional, this can lead to damp misdiagnosis, where the recommended solution does not address the true cause of the problem.
• No pressure to sell damp proofing
• Diagnosis based on evidence, not assumptions
• Clear explanation of what the problem is – and what it is not
• Advice that puts the property first, not the invoice
What We Assess During a Damp Survey
Every independent damp survey includes a thorough assessment of the following:
• Property age and construction type
• Internal moisture patterns and visible symptoms
• Ventilation levels and airflow
• External defects such as pointing, render, and guttering
• Ground levels and bridging risks
• Previous damp treatments or repairs
• Salt contamination and historic damp indicators
Rising damp is only concluded when all diagnostic conditions are met, not based on moisture meter readings alone.
During an independent damp survey, we assess a range of potential causes including condensation-related moisture, penetrating damp caused by external defects, historic or residual damp, and genuine rising damp where all supporting diagnostic conditions are present.

What You Will Receive
• A written damp survey report
• Clear diagnosis explained in plain English
• Photographic evidence where relevant
• Honest recommendations based on findings
• Advice on when no treatment is required
When an Independent Damp Survey Is the Right Choice
An independent damp survey is ideal if you want clear, unbiased advice before committing to any work.
• Buying or selling a property
• Damp proofing has failed previously
• Conflicting advice from contractors
• Older or solid-wall properties
• You want reassurance before spending money
What We Don’t Do
• We don’t diagnose solely from meter readings
• We don’t recommend damp proofing unless it is genuinely required
• We don’t use scare tactics or pressure selling
• We don’t treat symptoms without addressing causes
Book an Independent Damp Survey
If you’re unsure about the cause of damp in your property or want honest advice before committing to treatment, an independent damp survey provides clarity and peace of mind.
If you have been advised to carry out damp proofing work but remain unsure whether it is necessary, an independent damp survey can help identify whether the issue is rising damp, condensation, penetrating damp, or a form of damp misdiagnosis that requires a different approach.
If you're considering booking, you can view the independent survey cost in advance for complete transparency.
Honest advice – even when the answer is no work is needed.
Rising damp is only diagnosed when supported by construction type, moisture patterns, salt analysis, and external conditions, not from moisture meter readings alone.
