Cornerstone is not a typical drying contractor as they are continually improving their knowledge base and employ the most up to date techniques both to measure moisture and to remove it.
They are extremely passionate about their work and know from experience that they are thorough, skilful and above all an honest practitioner. Andrew Dallen had an involvement in a textbook I put together in 2009, in which he helped me understand a number of the drying techniques they use.
I have also been involved with Andrew in undertaking building inspections. Like myself, they use a huge range of inspection equipment – from borescopes and endoscopes to thermal imaging equipment and the best moisture meters and accessories available on the market and, like myself, he is intensely curious. There are few textbooks on the subject of dampness investigation and precious little nationally funded research. We are both therefore pioneers in this difficult and challenging field.
