RICS Level 3 Building Survey in Instow

The majority of properties in Instow were constructed during the Victorian and Edwardian periods, meaning they were built using traditional methods that differ significantly from modern construction. These period properties often feature solid walls rather than cavity walls, lime-based mortars instead of cement, and original timber frames that may have settled over more than a century. A RICS Level 3 Survey specifically examines these construction features and identifies issues that could affect the property's structural integrity or require expensive future repairs. Our surveyors understand that solid wall construction relies on breathability to manage moisture, and we know how to identify when this has been compromised by inappropriate modern interventions.

The coastal location of Instow presents unique considerations for property buyers. Properties near the river confluence and coastline face exposure to salt air, which can accelerate corrosion of metal fixtures and deterioration of certain building materials. Our surveyors specifically look for signs of coastal weathering, salt damage, and any previous flood damage that may have affected properties in this riverside village. Given Instow's position at the meeting point of the Taw and Torridge rivers, we pay particular attention to flood risk indicators and any evidence of previous water ingress at lower floor levels. Understanding these local factors is essential when purchasing in Instow, as they can significantly impact both the immediate condition of the property and future maintenance requirements.

Properties in Instow that would particularly benefit from a Level 3 Survey include those built before 1911, any listed buildings you might be considering, and properties showing visible signs of structural movement or significant defects. The older housing stock across the village, from terraced cottages near the cricket ground to larger detached homes along the waterfront, all share common characteristics that require experienced assessment. We also recommend Level 3 Surveys for properties that have been previously modernised, as inappropriate alterations to period buildings can create hidden problems that only a detailed structural survey will uncover.

• Comprehensive structural assessment
• Detailed defect analysis
• Repair cost estimates
• Tailored to period properties
• Flood risk assessment
• Coastal weathering inspection

Our experience surveying properties throughout the Instow area has revealed several recurring themes that buyers should be aware of. Properties built before 1911 typically feature solid external walls that rely on breathability to manage moisture. Modern cement-based renders or tanking applied to these walls can trap moisture, leading to severe damp problems that manifest as damp patches, peeling decoration, and deterioration of internal plaster. Our surveyors are trained to identify these issues and distinguish between historic damp management systems and problematic modern interventions. We frequently see properties where well-meaning but inappropriate modern treatments have caused more harm than good, trapping moisture within walls that were designed to breathe.

Timber defects represent another significant concern in Instow's older properties. Original wooden floorboards, structural beams, and window frames have been in place for over a century, and while well-maintained timber can last indefinitely, exposure to moisture and insect activity can cause rot and woodworm infestation. The coastal environment may accelerate these issues, as salt air can affect the durability of some metal fixings and accelerate the degradation of untreated timber. Our survey includes thorough assessment of all accessible timber elements, checking for signs of active woodworm, wet rot, and dry rot that could compromise structural integrity. We probe suspected timber with appropriate tools and assess the condition of joints and connections.

Roofing problems frequently feature in our reports for Instow properties. Original slate and tile roofs over 100 years old often have slipped or broken coverings, deteriorated pointing, and damaged flashings. Given the wet Devon climate, even small defects can allow water ingress that damages internal ceilings and structural timbers. Our surveyors inspect roofs from both inside accessible roof spaces and externally where safe access is possible. We assess the condition of ridge tiles, valleys, and penetrations, noting any areas where water could potentially penetrate the building envelope. The age of many roofs in Instow means that replacement or significant repair is often something buyers should budget for.

The riverside location of Instow also means we pay particular attention to flood risk and any history of flood damage. Properties at lower elevations, particularly those near the river confluence, may have experienced flooding at various points in their history. We look for signs of previous water damage at lower floor levels, including tide marks, displaced plaster, and modern flood resilience measures that might indicate past issues. While flood risk is considered in our overall assessment, we recommend that buyers also check the Environment Agency flood maps and consider specific flood risk assessments for properties in higher-risk areas.

• Rising and penetrating damp
• Timber rot and woodworm
• Roof defects and tile slippage
• Structural movement and cracking
• Outdated electrical systems
• Poor insulation standards
• Flood risk indicators
• Inappropriate modern alterations

Properties in Instow reflect the traditional building methods that were common throughout North Devon during the Victorian and Edwardian periods. Many homes were constructed using local stone, cob, and brick, with variations depending on the specific location within the village and the period of construction. Understanding these traditional methods is essential for accurate assessment, as they behave differently from modern construction and require specific expertise to evaluate properly. Our surveyors have direct experience with the various construction types found throughout Instow and understand how to identify defects that are typical of each method.

Lime mortar was the standard binding agent for period properties, providing flexibility and breathability that modern cement mortars cannot match. Over time, many properties have had cement-based mortars applied during repairs, which can cause problems by trapping moisture within the wall structure. Our survey includes assessment of mortar type and condition, identifying where inappropriate modern materials may be causing or contributing to damp problems. We can advise on the benefits of returning to lime-based repairs for period properties, which is often the preferred approach for listed buildings and those in conservation areas.

Roofing materials in Instow typically include natural slate, which was imported for higher-quality properties, and locally produced clay tiles. Some older cottages may feature thatch, particularly those of more ancient origin. Each roofing material has its own characteristic defects and maintenance requirements, and our surveyors know what to look for with each type. We assess the remaining lifespan of existing coverings, the condition of supporting timbers, and any signs of previous repairs or alterations that might affect performance. For properties in the conservation area, we note any works that might require listed building consent.
