Damp Survey
At Marshall Laurence Surveyors, our RICS Chartered Surveyors carry out independent, detailed Damp Surveys to identify the type of damp, its root cause, and the most effective solutions. Using advanced tools such as thermal imaging cameras and moisture meters, we provide a clear, accurate assessment so you can take the right action quickly.
What is a Damp Survey?
Damp is one of the most common and damaging property issues faced by homeowners in London and the South East. Left untreated, it can lead to structural deterioration, mould growth, and costly repairs.

What's Included In Our Damp Surveys?
Our Damp Surveys investigate all common forms of damp, including:
Rising Damp
Caused by ground moisture travelling up through walls due to failed damp-proof courses.
Penetrating Damp
Resulting from leaks, faulty gutters, cracked render, or external defects.
Condensation & Mould
Often linked to poor ventilation or insulation, common in London flats and converted properties.

Hidden Leaks
Located using thermal imaging and moisture detection equipment.
Internal & External Checks
Assessment of walls, floors, roofs, windows, and drainage systems.
Repair Guidance
Clear recommendations and maintenance advice to resolve issues and prevent recurrence.

Frequently Asked Questions
1. What is a Damp Survey?
A Damp Survey is a specialist inspection carried out by a RICS Chartered Surveyor to identify the type, cause, and extent of damp within a property. It provides clear advice on remedial works and how to prevent the issue from recurring.
2. Do I need a Damp Survey if I already have a Homebuyers Survey?
A Level 2 or Level 3 survey will highlight signs of damp, but a Damp Survey goes into much greater detail. If damp was flagged in your original survey — or you suspect it — a dedicated Damp Survey is the best way to understand the root cause and next steps.
3. What types of damp do you check for?
We assess all main types:
- Rising Damp
- Penetrating Damp
- Condensation & Mould
- Cold Bridging and Hidden Leaks
4. How do you detect damp?
We use a combination of visual inspection, moisture meters, thermal imaging cameras, and, where necessary, leak detection equipment. This allows us to pinpoint hidden issues and confirm the true cause.
5. Can you find hidden damp behind walls or floors?
Yes. While we do not open up structures, thermal imaging and moisture readings help identify hidden damp areas that may not be visible to the naked eye.
6. Do you sell damp-proofing or remedial works?
No — we are independent RICS Chartered Surveyors. This means our reports are completely impartial, with no vested interest in selling treatments. We give you the facts and recommend the most appropriate action.
7. How long does a Damp Survey take?
Most inspections take 1–2 hours, depending on the size and condition of the property. Larger or more complex cases may take longer.
8. How quickly will I get my report?
We typically deliver Damp Survey reports within 3–5 working days. Faster turnaround is available if required.
9. Will my report include repair advice?
Yes. Your report will outline the likely cause of the damp, repair recommendations, and maintenance tips to prevent it returning.
10. Do I need a Damp Survey in London properties?
Yes, London’s older housing stock is particularly prone to damp due to age, poor ventilation, and historic construction methods. A Damp Survey gives you reassurance and can save thousands in potential repairs.
