RICS Level 3 Building Survey in Davidstow

The housing stock in Davidstow differs markedly from typical UK residential areas, and this has significant implications for prospective buyers. The village and its surrounding parish feature a high proportion of detached properties, many of which are historic farmhouses or converted agricultural buildings constructed using traditional Cornish methods. These properties typically feature thick stone walls, slate roofing, and sash windows, all of which require a surveyor with specific knowledge of traditional building physics. A Level 3 survey from our team ensures that these unique construction features are properly assessed, with particular attention to how they perform against modern standards of weather resistance and thermal efficiency.

The local geology adds another layer of complexity to property inspections in this area. Davidstow sits on Devonian and Carboniferous sedimentary strata, with the Tintagel Volcanic Formation underlying much of the parish and granite intrusions from Bodmin Moor in the vicinity. Properties in this geological setting may experience different ground conditions compared to other parts of the UK, and our inspectors are trained to look for signs of settlement, subsidence, or movement that could relate to these underlying conditions. While the area generally presents low risk for river flooding, surface water runoff can be a consideration due to the local topography and high rainfall typical of North Cornwall. The parish includes several boggy hollows where water collects during wet periods, and this can affect the foundations of nearby properties.

Many properties in the Davidstow area will have been constructed using materials and techniques that are now considered non-standard. Traditional lime mortar pointing, local granite stonework, and historic roof slating all require specific expertise to assess accurately. Our surveyors understand that these features are not defects but rather characteristic elements of Cornish heritage that require appropriate maintenance approaches. We provide advice that helps property owners understand how to preserve these traditional features while addressing any genuine structural concerns that may arise during our inspection. This is particularly important for properties that may be listed or located within the setting of listed buildings.

The rural nature of Davidstow also means that many properties rely on private water supplies, septic tanks, or bespoke drainage systems rather than mains connections. Our Level 3 Survey includes assessment of these services where they are visible and accessible, though we always recommend that buyers commission separate specialist testing for water quality and drainage functionality. Properties near the Inny Vale holiday development, for example, may have specific construction types such as timber-framed lodges that require tailored inspection approaches.

• Traditional stone wall construction
• Slate roofing systems
• Lime mortar pointing
• Historic window joinery
• Private water and drainage systems

Our experience surveying properties throughout North Cornwall has identified several recurring issue categories that buyers in the Davidstow area should be aware of. Damp and mould penetration is perhaps the most common finding, particularly in older stone-built properties where the breathability of walls has been compromised by modern cement-based renders or tanking systems. Traditional Cornish buildings were designed to manage moisture through evaporation, and when this natural process is prevented by inappropriate modern treatments, moisture can become trapped within the wall structure, leading to deterioration of timber elements and potential health concerns for occupants. We frequently find that properties have been treated with non-breathable paints or cement render that are causing ongoing damp problems.

Roofing problems represent another significant category of defects in the Davidstow area. The prevalence of slate roofing on older properties means that we frequently encounter slipped or missing tiles, deterioration of lead flashings, and decay of underlying timber battens and rafters. Many historic roofs in this part of Cornwall were constructed with pegged slate fixed to timber battens using nails that may have corroded over time. Our inspectors pay particular attention to these roof conditions, as water penetration through a defective roof can quickly lead to extensive internal damage that may not be immediately visible from ground level. Properties in exposed locations near the high ground of the parish may experience more severe weathering due to prevailing Atlantic winds.

Structural movement and cracking are also encountered relatively frequently in the Davidstow housing stock. Properties built on shallow foundations in older ground conditions may exhibit signs of settlement, particularly where drainage from neighbouring fields or changes in soil moisture levels have affected the supporting soil. Our surveyors are trained to distinguish between harmless age-related settlement and more serious ongoing movement that might require structural intervention. We provide clear guidance on the nature of any cracking observed, including whether it appears to be active and what, if any, remedial works might be appropriate. In some cases, we may recommend monitoring the crack over a period of months to establish whether movement is ongoing.

Holiday-let properties in the Davidstow area, such as those in the Inny Vale development, may present different defect profiles compared to traditional residential properties. These timber-framed lodges often have specific issues related to their modular construction, including potential problems with joins, fittings, and the long-term durability of timber frame elements in a coastal environment. If you are considering a property intended for holiday rental, we can tailor our inspection to address the specific concerns relevant to this type of property.

• Damp and mould in stone walls
• Slate roof deterioration
• Structural cracking and settlement
• Timber decay in roof voids
• Defective flashings and gutters
• Condensation in converted buildings
• Mundic concrete in post-1900 properties
