Send us a unit.

Genuinely — if a piece has already come down, put it in a box with packing round the arrises and post it. We mould from the original and nobody has to interpret a photograph.

   A surviving unit, if one has already come down

   Best case by a distance. We mould from the original, so the profile, the arrises and the surface texture come across without anybody interpreting them.

2. 02

   Photographs square-on and raking, with a rule in frame

   Square-on gives the outline, raking light gives the depth. A rule in the frame is what turns a photograph into a measurement.

3. 03

   A profile template, if you can reach the unit safely

   A strip of card cut to the section beats twenty photographs. If reaching it is not safe, skip it — we will take it off the mould instead.

4. 04

   The relevant page of your inspection report

   It tells us what the engineer actually flagged, which is often narrower than what the contractor quoted for.
