Establishing the cause(s) of damp defects

Leading Independent Consultancy



Damp Defects

We are a specialist consultancy investigating and resolving damp-related defects in both historic and modern buildings.

We assess all moisture related problems, including rising damp, penetrating damp, condensation, and residual moisture from fire and flood, while also considering defects associated with damp environments such as fungal and insect damage, and mould.

Our holistic solutions provide cost-effective and longterm strategies that have been refined by 25 years of practical experience and relevant academic understanding.

Quality Information

We would like to discuss what is the most proportionate approach for your specific situation, what best meets your objectives, discussing any plans for the building that could influence the guidance we provide.

We employ a full range of testing methodologies to help establish the source of moisture, evaluating its distribution, and establishing if it is a current or historic problem; strategies range from non-destructive moisture profiling utilising resistance meters and thermography, to full gravimetric moisture and salt analysis (as described in BRE Digest 245), which is the most accurate scientific assessment currently available.

In some circumstances i.e. disputes, only full quantitative analysis will suffice, and its destructive nature will be accepted. However, such interventions are not always acceptable: for instance, the vendor of a pristine up-for-sale house may not permit such disruption.This is when our experience and knowledge of building design, materials and defects, and our least invasive approach, will help ensure the most successful outcome.

We pride ourselves on providing the best longterm solutions for troublesome damp issues.
