About us

After experiencing fundamentally opposing methods of investigating and solving damp and timber defects – from the minimalist approach absorbed while training and working in building conservation, to the product-lead, interventionist approach experienced during a period working for local remedial companies – we formed our company in 2005 to provide an approach based on scientific understating, building conservation and sustainability best practice, all guided by 3 fundamental principles:

Holistic Approach – Promoting informed investigation, minimal intervention and holistic strategies, applying the principles of building conservations for the benefit of all projects.

Ecology –  Not only do we resolve and design out and therefore prevent building defects, we aim to improve our clients health and well-being within their built environment and continually strive to minimise the environmental impact of our activities and look for opportunities to enhance the wider ecology.

Equitable business – To be transparent and fair in all our activities.

“The secret of change is to focus all of your energy, not on fighting the old, but on building the new”

Socrates
