Older, solid-walled homes
21% of the housing stock in these neighbourhoods dates from before 1919 and 20% 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.

Flood risk (rivers and sea)
17 of the 100 postcodes we checked (postcodes where homes sold in 2025) have their centre in Environment Agency Flood Zone 2 or 3, and 13 in Zone 3. Check the specific address on the government's flood risk service and get insurance quotes before exchange.

Radon
The 1 km radon map square at the centre of Tiverton is class 4: an estimated 5 to 10% of homes are above the radon Action Level. 100% of the sold postcodes we checked fall in a radon Affected Area. It's invisible and odourless, so the only way to know is a test; ask the seller, or budget for one after you move in.

Ground and building stone
Under most of Tiverton the bedrock is interbedded sandstone and conglomerate (81%) and mudstone, siltstone and sandstone (19%). In Devon, older homes on this ground are often cob (earth walls) or local stone; cob must stay dry, so look hard at renders, gutters and ground levels.

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