“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 do still offer a service as a specialist contractor firm on a very modest level”.

Examples of chargeable inspections and consultations:

– Pre-purchase or Pre-sale Damp & Timber surveys.

– Pre-purchase general appraisals (prior to making an offer)

– Any inspection where a formal diagnosis of dampness, decay, infestation or structural issue is required.

– Advice regarding mould growth or potential condensation issues.

– Inspection of rental properties, commercial premises and holiday cottages.

– Dispute Resolution reports.

– To prepare remedial specifications for works to be undertaken independently by others.

My own professional fees are usually 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 specific and helpful, and my advice has saved clients thousands of pounds on many occasions, by avoiding unnecessary or inappropriate work previously recommended by others.

Basement Waterproofing


Following the revision of BS8102 in 2009 which now requires the involvement of a CSSW qualified waterproofing designer, waterproofing of below-ground structures such as retaining walls, existing cellars or new-build basements has become the largest element of the work we undertake. We are Approved Installers for Newton Waterproofing systems and other brands.

I am able to design and specify (and install if required) 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

The 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 have sustained some degree of rising damp, 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 

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 many of our bespoke reinforcement designs can be guaranteed and insured.

Plastering & pointing

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


Because we are such a small firm we need to restrict our work to our specialist elements only, and therefore we do not undertake any of the following:

General leaks / maintenance issues

External guttering, soffits or rainwater goods.

Defective window joinery

Woodworm treatments in furniture and internal joinery

Extensions or general new-build work

Roof coverings








“You've save me a fortune!”


“its nice to work with a small local specialist who we can talk to”


“David came very highly recommended as a specialist by my building surveyor, and I was not disappointed”

Lead Time and availability

Demand is exceptionally high at present, and should your enquiry be allocated an appointment, current lead-time for surveys and inspections is approximately 5-6 weeks depending on location.

Generally I do receive many more enquiries than it's possible 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.


With the Coronavirus risk still present and on-going, surveys and site inspections will be considered ONLY when considered to be sufficiently urgent, and strict criteria may apply. Please let us 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.
