Surveyors · Port Isaac, Cornwall
Surveys for Port Isaac buyers, with Port Isaac's own numbers: house prices, building age, flood zones and radon.
Our suggestion for Port Isaac
In Port Isaac, we'd usually point buyers to a Level 3 Building Survey. Older construction is where Level 3 earns its fee: it digs into walls, roofs and timbers and tells you what repairs to budget for. Newer homes here may only need a Level 2.
In 2025, 11 homes sold in Port Isaac at a median price of £360,000, down 4% on 2024's £375,000.
Sales mix: detached 36%, terraced 27%, semi-detached 18%, flat/maisonette 18%. PL29. HM Land Registry, 2025, ONS built-up area. Residents: Port Isaac built-up area, ONS Census 2021.
Before-1919 homes make up 44% of the stock here. Solid-walled houses behave differently from modern ones; watch for hard cement pointing and modern coatings that hold moisture in, and treat any 'rising damp' diagnosis from a damp-proofing salesman with caution.

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.

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