Building Pathology-00Building Pathology


Over the last fifteen years our philosophy has been to specify remedial works after obtaining a full understanding of the building and the processes and mechanisms of decay organisms and beetles.  By reducing the moisture content of the building fabric to safe levels fugal decay will die and insect infestations will be controlled.  This avoids unnecessary chemical spray treatments.

Building Surveys

dry-rotOur surveys provide independent detailed information and practical recommendations clients need for cost effective remedial or refurbishment work.  We offer clients advice on the control of damp in buildings and the severity of timber decay organisms including dry rot, wet rots, deathwatch beetle and furniture beetle detailing sustainable solutions that do not rely on damaging interventions or chemical treatments.  We provide our clients with a cost effective appraisal of their buildings often saving substantial sums of money frequently wasted on inappropriate or unnecessary beetle infestation treatments or invasive dry rot repairs which in many cases results in the loss of significant amounts of historic fabric.
