Older, solid-walled homes
33% of the housing stock in these neighbourhoods dates from before 1919 and 33% 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)
3 of the 19 postcodes we checked (postcodes where homes sold in 2025) have their centre in Environment Agency Flood Zone 2 or 3, and 3 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 Modbury 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.

Mundic
Mundic (decaying concrete made with mine waste) is mainly a Cornish issue, but lenders also ask about it in parts of Devon such as South Hams. A pre-1950 concrete-block home here may need a mundic test.

Ground and building stone
Under most of Modbury the bedrock is mudstone, siltstone and sandstone (85%). Older homes are often built of local stone; check pointing, wall heads and chimney stacks.
