General Conservation & Care Principles

 

Many examples of architectural metalwork have been around for generations, and we have a responsibility to hand them down again to the next.
Dorothea Restorations developed a “first of its kind” conservation policy which set the industry standard for conservation works which you can read here. Some of the most basic and fundamental principles to sensitive and correct conservation are listed below.

  • Use acknowledged experts - Independent and objective advice from the right people is fundamental. Only employ skilled and experience craftsmen with knowledge of conservation work
  • Only repair the parts of the structure that really need it – Replacement is always a last resort and even then needs careful consideration for the existing ironwork and historical context
  • Ensure correct materials and recognised repair techniques are used and that even the smallest alterations made are done well
  • Understanding the reasons for failure of any metalwork before undertaking repair works is fundamental.
  • Keep well organised records of all restoration works undertaken.
  • Don’t look at problems in isolation – consider them in the context of the building as a whole
