Older, solid-walled homes
67% of the housing stock in these neighbourhoods dates from before 1919 and 66% 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)
2 of the 11 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 Mousehole 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. Ask the seller for any radon test result, or test after you move in; remedies are usually straightforward.

Mining and mundic
Expect your conveyancer to order a mining search, and if the home has pre-1950 concrete blocks, a mundic test may be a lender condition.

Ground and building stone
Under most of Mousehole the bedrock is mudstone, siltstone and sandstone (91%). This is the 'killas' country of slate and shale; older homes are often rubble stone, sometimes slate-hung, and weathering of soft stone and mortar is common.

Coastal exposure
Mousehole is within about 0.3 km of the open coast. Salt air shortens the life of metal fixings, window frames and render, and wind-driven rain finds weak spots in walls.
