RICS Level 3 Building Survey in Craster

Craster presents unique challenges for property purchasers that make a Level 3 Survey particularly valuable. The village boasts a distinctive building heritage constructed primarily from local Craster Whinstone, a hard dark basalt that gives properties their characteristic sombre appearance. This traditional stonework, while visually striking, requires expert assessment to identify potential issues that may not be apparent to untrained buyers. The volcanic origin of this material means it behaves differently from sandstone or brick, and our surveyors recognise the specific defects that commonly affect whinstone construction.

The majority of properties in Craster and the surrounding NE66 3ST postcode area date from the pre-1919 period, with many incorporating elements of medieval and Georgian architecture. Craster Tower, a Grade II* listed 14th-century pele tower, exemplifies the age and construction complexity found throughout the area. Properties of this age often suffer from dampness, timber decay, and structural movement that accumulate over decades of occupancy. Our inspectors have extensive experience evaluating these traditional buildings and understand how to distinguish between historic settlement patterns and active structural concerns.

Additionally, Craster's coastal location brings specific environmental considerations. Properties within this area face potential flood risk from both coastal sources and surface water runoff, particularly given the local geology and the Northumberland coastline's susceptibility to erosion. The Northumbria River Basin District, which includes Craster, is at risk from river, surface water, and coastal flooding, with over 39,000 people at risk from rivers and the sea in the wider district. Our inspectors assess drainage, retaining structures, and flood resilience as part of every comprehensive survey.

Several properties in Craster are either listed or fall within the proposed conservation area, which brings additional planning considerations. Craster and Dunstan were specifically considered for conservation area designation in 2021, with the appraisal identifying the historic harbour and its relationship with Craster Tower as particularly significant. Our surveyors understand these constraints and can advise on the implications for any renovation work you are considering.

Properties in Craster exhibit the distinctive characteristics of traditional Northumberland coastal architecture. The predominant building material is Craster Whinstone, a hard blue-grey basalt of volcanic origin that provides exceptional durability but requires specific expertise to assess properly. Sandstone is also used extensively, particularly in more prestigious buildings such as Craster Tower, where the Georgian South wing is faced in local whinstone contrasting with the sandstone used for the rest of the house. Roofs typically feature blue or heather slate or red pantile tiles, with windows often having decorative stone surrounds.

The geological context of Craster is particularly interesting for structural assessment. The village sits on the Whin Sill, a major igneous intrusion that forms the dramatic coastal cliffs visible from the village. While this bedrock provides generally stable foundations, superficial deposits can vary significantly across short distances. Our surveyors examine drainage patterns and ground conditions carefully, as clay-rich deposits in some areas may present shrink-swell potential during seasonal moisture changes, though the risk in Craster is generally low to medium given the predominance of basalt and sandstone.

Properties incorporating historic pele towers, such as Craster Tower and Dunstan Hall, represent a particularly specialized construction type. These fortified buildings feature extremely thick walls, often with vaulted basements, and require structural assessment by surveyors experienced in evaluating traditional vernacular architecture. The combination of age, traditional materials, and coastal exposure means that even seemingly minor defects can have significant implications if left unaddressed. Many former industrial buildings, including the traditional smokehouses that form part of Craster's economic heritage, also require specialist assessment.

Understanding the age of the property is crucial for appropriate survey scope. While Northumberland as a whole has a median construction year of 1981, Craster's historic core contains a significant proportion of properties built before the 1940s, with Craster Tower dating back to the 14th century. The village's traditional housing stock consists largely of stone-built cottages, likely terraced or semi-detached, reflecting its heritage as a fishing community. Our surveyors adjust their inspection approach accordingly, recognising that older properties require more detailed assessment.

• Craster Whinstone walls
• Sandstone features
• Slate and pantile roofs
• Thick solid walls
• Traditional lime mortar pointing

Based on our experience surveying properties throughout the Craster area, several recurring issues frequently require attention. Dampness ranks among the most common problems, particularly in traditional solid-walled properties where modern damp-proof courses may be absent or compromised. The coastal exposure accelerates moisture ingress, and properties with restricted ventilation suffer from condensation issues that can lead to timber decay. Our inspectors assess damp levels using professional equipment and identify the specific causes rather than simply noting the presence of moisture.

Structural movement is another frequent finding in older Craster properties. While some settlement is normal in age properties, our surveyors assess whether movement is active and whether previous repairs have been appropriately addressed. Cracking in stone walls requires careful evaluation to distinguish between minor cosmetic issues and structural concerns that may affect building stability. We pay particular attention to the condition of lime mortar pointing, as repointing with cement mortar can trap moisture and cause stone faces to spall in freeze-thaw cycles.

Roof condition represents a significant consideration given the local climate. Slipped tiles, deteriorated pointing, and damaged flashing all allow water penetration that can cause extensive damage to rafters, insulation, and internal finishes. Our surveyors inspect roofs from both inside and outside where accessible, providing detailed assessments of condition and remaining lifespan. The typical slate and pantile roofs found in Craster can have varying lifespans depending on their original quality and exposure to coastal weather.

Electrical and heating systems in older properties frequently require updating to meet current standards. Many traditional Craster homes still have original wiring that may not comply with modern regulations, and heating systems often rely on older technologies that may be inefficient or unsafe. Our survey includes assessment of these services with clear recommendations for improvement where necessary. Given the age of the housing stock, we also check for the presence of legacy materials such as asbestos-containing materials or lead water pipes.

• Rising and penetrating damp
• Timber rot and woodworm
• Roof defects and leaks
• Structural cracking
• Outdated electrical systems
• Inadequate insulation
