Older, solid-walled homes
27% of the housing stock in these neighbourhoods dates from before 1919 and 26% from before 1900. Expect solid walls rather than cavities, so damp diagnosis needs care: cement renders, plastic paints and raised ground levels trap moisture in walls that were designed to breathe.

Ground and building stone
Under most of Colyton the bedrock is mudstone, siltstone and sandstone (100%). Local stone is common in older houses, so pointing, chimney stacks and the tops of walls deserve a close look.

Ground stability
The BGS GeoSure 5 km hexagon covering Colyton shows moderate shrink-swell clay, significant slope instability (landslides), significant soluble rocks (dissolution) potential. That's a broad screen, not a site assessment; look for cracking, sticking doors and leaning walls.
