Older, solid-walled homes
39% of the housing stock in these neighbourhoods dates from before 1919 and 38% 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.

Listed buildings
Historic England lists 19 buildings in and around Stithians, including Church Of St Stythian (Grade II*). Listed status affects windows, renders and repairs, so check what consent exists for work already done.

Flood risk (rivers and sea)
2 of the 13 postcodes we checked (postcodes where homes sold in 2025) have their centre in Environment Agency Flood Zone 2 or 3, and 2 in Zone 3. Look up the exact property, not just the postcode, and get an insurance quote early.

Radon
The 1 km radon map square at the centre of Stithians is class 6: an estimated 30% or more of homes are above the radon Action Level. 100% of the sold postcodes we checked fall in a radon Affected Area. A three-month radon test is cheap, and fixes (often a sump or better underfloor ventilation) are well understood.

Mining and mundic
Cornwall's metal-mining history means conveyancers usually order a mining search, and concrete-block homes built before about 1950 may need a mundic test for a mortgage.

Ground and building stone
Under most of Stithians the bedrock is granite (BGS class: felsic rock) (100%). Granite areas tend to have higher radon, and granite-built homes are tough but can suffer driven-rain penetration through joints.

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