Haven't visited, Kev, so no pics. As far as I can gather its 2 square rooms totalling about 40 sq m of old (200 - 300 yrs) traditional suffolk clay paviours that need cleaning from built up day-to day soil (not builders work, etc) and sealing.
I'd like to pass details to the customer, because that's what I said I'd do.
Don't think I deserve a commission, really, just hope that if someone gets a lead in our area (Cambridge, Bury St Edmunds, Ely, St Neots are around the edge) they'd pass it on.
