“Good, qualified advice has often saved my clients thousands of pounds”.

For the majority of my enquiries some form of survey and professional diagnosis is required in the first instance, and I naturally charge for any type of investigation and report which includes an offer of diagnosis or any element of professional liability.


“Consultancy, CSSW waterproofing design and damp diagnosis are the main part of my personal workload these days, however if clients are unable to arrange for remedial work to be undertaken independently I may still offer a service as a specialist contractor on a very modest level”.

Quote or Estimae on applicaiton

My own professional fees are typically much lower than those of other professionals such an Architect, Engineer or Chartered Building Surveyor, however in many cases my advice can be much more targeted, relevant and helpful, and I have saved clients thousands of pounds on many occasions. I like to use my knowledge and experience to guide my clients through the maze of conflicting and often inaccurate infomation / mis-information which surrounds our industry.

sBasement Waterproofing


Following the revision of BS8102 in 2009 and 2022 which now requires the involvement of a CSSW qualified waterproofing designer, waterproofing design for below-ground structures such as retaining walls, existing cellars or new-build basements has become the largest element of my work, primarily working closely with Newton Waterproofing systems and other brands.

I am able to design, specify and fully guarantee a bespoke waterproofing system using one or a combination of the many excellent systems and products on the market, backed by my qualifications, experience and comprehansive Professional Indemnity Insurance cover.

Rising Damp Control

Over the past 60 years the damp-proofing sector of the industry has acquired a poor reputation (quite rightly in my opinion) however there have been very significant improvements in recent years and the vast majority of contractors now operate in a much more ethical and informed manner. There have even been publications claming that rising damp does not exist although this is overwhelimgly disproved. The fact is that majority of buildings constructed in Cornwall before around 1900 were not built with any form of damp-proof course (DPC) at the base of the walls and many of these buildings have sustained some degree of rising damp during their history, which affects only the lower parts of the walls.

There are a number of ways that active rising damp can be managed, controlled or eliminated, and a sound understanding and correct management of the associated residual hygroscopic salt contamination ensures an effective overall result.


There are a number of different species of wood-boring beetle which affect timbers within buildings in the UK, and all are treatable in one way or another although a correct diagnosis is essential.

Dry-Rot & Wet-Rot

There are a number of common species of wood-rotting fungi which are found in our buildings, many of which can look very similar in the way they appear and the way they destroy the timber and this is why expert diagnosis is essential. A good understanding of the nature and biology of the various wood-rotting fungal species is necessary to effectively treat decay with the minimum of disruption.

Structural reinforcement 

I’m not a structural engineer, however I do have extensive experience in remedial structural  repairs in masonry walls. I can specify low-disturbance, working structural masonry repairs and reinforcement for most common problems including bowed and cracked walls, failed lintels and settlement. Most standard repair specifications and bespoke reinforcement designs can be guaranteed and insured.

Plastering & pointing

Whilst I do not operate as a contractor I can advise on work such as specialist replastering, repointing, rendering and general repairs often associated with damp-related and structural works.

Book a Survey or Consultation

Due to present demand and workload, my current lead-time for surveys and inspections is approximately 4 weeks.

I typically work Monday to Thursday (not Fridays or weekends) from typically between 7.30am - 5.30pm and generally try to get back to my office most afternoons for my report-writing and general office-based work and emails etc.

I do have a land-line and answerphone, however I do prefer EMAIL ENQUIRIES where possible.

Priority will always be given to my longstanding regular clients or to those others which I consider to be of particular urgenty and importance.

Most of the time I do receive more enquiries than it's possible for me to service and I therefore need to prioritise my limited survey appointments accordingly, although I will endeavour to REPLY to all email enquiries within a few days 

In some cases I can provide advice or estimates based on sufficient photographs or drawings etc, which can be emailed to me directly for a desktop inspection and I am still providing my popular desktop waterproofing design service.


I am generally happy to be guided by my clients regarding the level of precaution required during surveys. Please let me know if there are any particular Covid precautions required, and in particular if there is anybody in the property who might be considered at particular risk.
