Heritage
The work
Sandstone, brick, render, cast and wrought iron, bronze and timber on buildings that can’t be replaced and are usually listed. Paint, soot, biological growth and corrosion, often built up over decades.
How we do it
The laser first, at the lowest setting that works, agreed with the adviser on the first pass. Photos of the surface before, during and after. We use conservation terms carefully and say so when something is outside what we do.
What you get
The photo record, the settings we used, and a method statement you can file with the heritage approval.
