Introduction to specific defect building survey

A specific defect survey is conducted by a professional building surveyor.  A Building Surveyor can sometimes be considered a ‘building doctor’ – we understand how buildings and structures are constructed and understand the common defects associated with each type of property and the associated causes. Whether your building is suffering from structural movement / damp issues / water ingress / timber defects or any other issue, our professional friendly team are here to help. 

Our team of experts combines the latest technology and in-depth knowledge to diagnose even the most complex defects, providing you with a comprehensive report and solution to keep your property in a good state of repair. Our holistic approach considers external and surrounding factors, which can further assist us when making a diagnosis. We believe that every building has its own story, and our goal is to help you uncover and solve any issues with precision and care.
