  • Sample brick/tile/beam presented on site
  • Photographic record of source (yard, salvage batch)
  • Written provenance where available (demolition site, era)
  • Matching pointing/mortar spec for brickwork

Frequently asked questions

+Does Sunderland accept reclaimed for Grade II works?

Yes — reclaimed is usually preferred over new for Grade II and Grade II* repairs.

+Is surplus PIR the same spec as new?

Yes — surplus is factory-fresh, just over-ordered. Same BBA cert and lambda value.

+Do I need a heritage consultant?

For Grade I and Grade II* yes. For local conservation area consents, a good architect suffices.
