Damp Surveys In Devon & Cornwall

Jonathan Young 07496 635 359
Independent Qualified Mould & Damp Surveyor


Jonathan is the head of damp surveying in the South West of the UK. Postcodes TR, PL, TQ, EX, TA and BS.

Jonathan is CSDD and CSRT  qualified – certified surveyor in damp detection and PCA qualified – and has gained a wealth of knowledge and expertise in the building industry from his time in HM Forces qualifying as an Architectural Technologist and building studies through to working abroad and architectural firms in the South West.

After this time spent in the architectural practice (2010), Jonathan has worked with design teams and clients mainly on a domestic level and working and running his own design business.

Coupled with this is him taking his building knowledge and diversifying into surveying of structures with regards to damp, timber and mould identification, diagnosis and strategies for remediation. This was supported by Jonathan carrying out his surveying qualifications (Damp, Timber & Mould) through the PCA (Property Care Association) in 2015.
A sound and extensive knowledge of how buildings work and function in different environments and situations has provided Jonathan with an excellent background to identifying and suggesting reasonable solutions to almost any damp and mould problem.

Jonathan has a particular keen interest in old and historic structures due to a large period of his construction experience dealing with grade 1 and grade 2 listed buildings.

As with all Damp Detectives, Jonathan will carry out a thorough inspection of your home to ensure that every possible cause is identified for your peace of mind and can provide a written report documenting simple and effective solutions.

During the Covid19  restrictions we are still able to help you in many ways. Please contact us  to learn how we can help.

How Does He Work?

Take a look below for a step by step guide to what is included in your South West Damp Survey and how Jonathan works.

1. Ethical Quoting

After you contact Jonathan, he will provide a no obligations assessment of your situation and at this time he will give you an initial idea of the cost of the survey. As a general guide, a Damp Survey for a property in the South West is less than the cost of a basic home buyers survey, providing excellent value for money.

2. Quick Response Time

We aim to conduct your survey to the time requirements you have specified which in our experience is normally within 3-4 days. If for whatever reason Jonathan is unable to complete your survey quickly this will be made clear to you during the initial assessment.

3. Site Visit

If you are happy with the assessment, Jonathan will arrange to come and visit the property and if necessary liaise with tenants, estate agents or the property owners to gain access to the property and undertake the survey. The survey itself normally takes average of 3 hours for a small residential property.

4. Survey Report

If you request a written report, Jonathan will send this to you via email or in the post within 24 hours of completing the survey.
As a Damp Detective Jonathan’s survey is very precise and by using a variety of scientific instruments he can track moisture through floors, walls and ceilings to get right to the root of the problem. Like all Damp Detectives he is totally honest, unbiased and independent and will explain his findings at every stage .

You will be completely satisfied with his survey and realise that often the remedy is quite simple. Saving you thousands of pounds in unnecessary remedial building work.

We can’t recommend Jonathan enough!He was extremely helpful throughout the process. Moving house is already expensive, but for the information we received has 100% saved us money and time and paid for itself. By reading the survey we new exactly what we were going to encounter and advice on how to resolve the issues. There were points that we would have never considered as contributors to the damp issue. The house was around 85% humidity when we bought it, but after the survey, advice and remedial works its rarely over 55%. I cant imagine buying any house again without having a damp survey.

Chris Brown

Jonathan was excellent, very knowledgeable and able to back his findings up with scientific, logical evidence put into laymans terms.
We should have done this years ago, it would have saved us a lot of money in the long run. Instead we relied on free quotations from blaggers and trawled through youtube hit and miss advice. Jonathan has presented us with bespoke advice specific to our issues. Great service.
