RICS Level 3 Building Survey in Ugborough

Ugborough's housing stock presents unique challenges that only a detailed structural survey can properly assess. The village contains numerous properties built from traditional cob construction, a method using clay-rich earth mixed with straw that requires specific expertise to evaluate. Many of these older buildings have been subject to inappropriate repairs over the years, using modern cement renders that trap moisture and cause damp problems. Our inspectors understand how traditional cob walls function and can identify when modern interventions have caused damage rather than preventing it.

The local geology presents another factor our surveyors consider when assessing Ugborough properties. Ugborough sits on slate and tuff bedrock, with clay-rich soils that can cause shrink-swell movement affecting foundations. Properties with shallow foundations, common in older buildings constructed before modern building regulations, are particularly vulnerable to subsidence. Our inspectors examine foundation conditions, wall stability, and signs of movement that might indicate these issues, paying particular attention to the legacy of historical mining activity at Redlake where china clay was extracted between 1913 and 1932.

Several properties in Ugborough fall within the designated Conservation Area or are listed buildings, including historic farmhouses dating from the 15th century such as Haredon Farmhouse. These properties require careful assessment as they may have specific restoration requirements or hidden structural problems from decades of alterations. A Level 3 survey provides the detailed analysis you need for any property in this area, identifying both urgent structural issues and longer-term maintenance considerations.

The age distribution of properties in Ugborough means the majority of homes were built pre-1919 using traditional construction methods that function very differently from modern buildings. With solid walls instead of cavity construction and roofs built on-site rather than using pre-fabricated trusses, these properties require experienced surveyors who understand how traditional buildings behave. We examine the condition of historic fabric, identify previous inappropriate repairs, and advise on approaches that comply with heritage requirements while addressing structural concerns.

• Stone and cob wall condition
• Roof structure and slate tiles
• Foundation and subsidence signs
• Damp and timber decay
• Conservation area considerations
• Listed building implications

Our inspectors frequently identify several recurring problems in Ugborough's older properties that buyers should be aware of before purchasing. Damp and mould issues are particularly common in traditionally constructed buildings where inappropriate modern repairs have been applied. Cement-based renders, while appearing to improve durability, actually trap moisture within cob and stone walls, leading to internal damp problems and deterioration of the structural fabric. We often find that what appears to be solid construction has been compromised by well-meaning but technically incorrect previous maintenance.

Roof conditions also require careful assessment on Ugborough properties given the prevalence of slate roofing throughout the area. Many properties feature natural or imitation slate roofing that can deteriorate over time, with broken tiles allowing water ingress that damages underlying timbers. Our surveyors inspect roof spaces thoroughly, examining rafters, battens, and any signs of past or current leaks that might not be visible from ground level. We check for adequate ventilation in roof spaces, as poor ventilation can lead to timber decay and condensation problems.

Structural movement and cracking affect many older properties in the area, and our surveyors are trained to distinguish between acceptable settlement and serious structural problems. We assess wall ties, joist ends, and connection points that might indicate progressive failure requiring urgent attention. In properties with cob walls, we look for signs of erosion at the base where moisture can cause the most damage, while stone-walled properties may show mortar deterioration or structural shifting at window and door openings.

Wall tie corrosion is a particular concern for properties where cavity walls have been insulation retrospectively or where original ties were poorly installed. Our inspection includes checking for signs of rust staining on external walls, bulging or distortion of wall surfaces, and separation of internal plaster from walls. Given the age of much of Ugborough's housing stock, this is an issue we encounter regularly in our surveys across the area.

• Damp penetration from failed renders
• Roof tile damage and leaks
• Structural cracks and movement
• Timber rot and woodworm
• Wall tie corrosion
• Foundation settlement

The Erme valley location means flood risk requires consideration for certain properties, particularly those in lower-lying areas closer to the river course. While Ugborough itself sits outside high-risk flood zones defined by the Environment Agency, the river network and surface water runoff during heavy rainfall can affect low-lying areas. Our surveyors note flood indicators such as water marks, damp staining at lower levels, and any signs of previous flooding that might not be immediately obvious. We advise on any necessary investigations or insurance considerations based on our findings.

Historical mining activity at Redlake, where china clay was extracted between 1913 and 1932, has left a legacy that can affect ground stability in some areas. Abandoned shallow mine workings occasionally cause subsidence issues, and our surveyors are trained to identify tell-tale signs that might indicate this type of ground instability. We examine external ground conditions for depression or uneven settlement patterns that could suggest mining-related issues. Where concerns are identified, we recommend further investigation through a mineshaft search or geotechnical survey.

The local environment also brings considerations from nearby coastal weather patterns despite Ugborough being approximately 7 miles from the coast. Properties exposed to prevailing winds may show accelerated weathering of roof coverings and external walls, particularly those on elevated positions in the valley. Our reports include observations about environmental factors specific to each property's position within the village and surrounding landscape, noting any exposure-related issues that may affect long-term maintenance requirements.

The underlying geology of slate and tuff, combined with the clay-rich soils common in the area, creates potential for shrink-swell movement that can affect foundations over time. This is particularly relevant for older properties with shallow foundations that were constructed before modern foundation depth requirements were established. Our surveyors examine walls for cracking that may indicate this type of ground movement, assessing whether the movement is active and what implications it may have for the property's long-term structural integrity.
