Surveyor Fixes Damp
Epidemic of misdiagnosis
Damp takes time and experience to diagnoses. The risk of damp has increased with modern living and reduced ventilation.
Fear of being sued has encouraged homebuyer surveyors who detect slight dampness, to “delegate” damp to specialist contractors who have a conflict of interest. The consequence is a rising damp diagnosis and chemical damp proofing.
Damp Surveys Ltd was founded to improve the accuracy of damp diagnosis and its treatment.
Science of water movement is complex. Water vapour, hygroscopic salts and rain are common causes of damp, but poorly understood and rarely subject to independent investigation before treatment.
Old buildings were not designed for modern living and reduced ventilation for heat conservation.
We challenge established thinking, accepting evidence only were it is verifiable.
Debunking received wisdom
Water is absorbed up a porous material. It has been proved to rise up to about 400mm from standing water.
The Property Care Association (“PCA”) and rising damp proofers point to examples of high salts bands as proof that damp can rise more than 400mm from standing water.
Watch this space
We have decided to test out the PCA’s theory. If they are wrong, which is likely. Then rising damp is virtually impossible unless a house is sitting in water.

If you can’t fix it yourself, request a damp survey
On site Damp Surveys will resume in London on 1 September 2020.
RICS qualified expert witness
As a RICS qualified expert witness, I have investigated thousands of damp walls in London to find the root cause of moisture.
- Of over 2,000 walls with dampness at the base of the wall, all were caused:
- vapour above or below ground level,
- hygroscopic salts mainly from chimney breasts,
- leaks or
- None of the damp was caused by rising damp.
- Most damp had beed misdiagnosed by a damp proofer.
- Most walls had been treated for rising damp that had failed.
Damp Survey Philosophy
Most damp and mould problems take minutes to stop, once the root cause has been correctly identify. This is especially true in London where groundwater is well below ground levels. The expertise and time taken is normally in the identification of damp i.e. expert damp surveyor, not in the solution.

Independent damp surveys
Using an array of devices and techniques we trace damp back to its source, fix the root cause (permission and time permitting) and provide a user-friendly damp report, with additional recommendations and prices – mainly London.
*We guarantee satisfaction or refund the full cost of our work, including any case of rising damp (none found so far).
The benefits of using an independent damp surveyor over a rising damp proofer (also known as contractors) are:
- Fix root cause of damp (not just symptoms).
- Stops risk of ongoing damage, such as from Dry rot.
- Consider everything, eliminate nothing.
- Conserve performance of old walls.
- Independent damp proofers are not trying to sell a product.
- Typically significantly cheaper in long run.
For clarity anyone entering into a contract is a contractor. Anyone fixing damp, with or without chemicals, is a damp proofer. PCA refer to chemical rising damp proofers, as contractors.
