Wind-driven rain is the first thing the surveyor weighs up. Gloucestershire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

As for paperwork, in Gloucester filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
