RICS Level 3 Survey in Stanton St Bernard

The village of Stanton St Bernard contains an unusually high proportion of historic buildings for its size, with properties dating back to the late 17th Century. Mill Farmhouse, a Grade II listed building at SN8 4LT, exemplifies the traditional construction found throughout the area, featuring stone walls, brick on stone plinth, and distinctive thatched roofing. These older properties require inspection by surveyors experienced with historic building techniques, as standard assessments may miss age-specific defects common to traditional construction. Our team has direct experience surveying properties across this village and understands the specific challenges posed by historic Wiltshire buildings.

Many properties in this area feature solid wall construction without cavity insulation, which can present different thermal performance and damp penetration characteristics compared to modern buildings. The presence of traditional lime-based mortars rather than cement also affects how moisture moves through walls and can influence the extent of any damp issues found during survey. Our team recognises these construction differences and knows what to look for when assessing properties in Areas of Outstanding Natural Beauty. We examine pointing condition, walltie corrosion, and the effectiveness of any past remedial works.

The local geology in Wiltshire includes shrinkable clay soil, which poses a potential subsidence risk for properties in Stanton St Bernard. During periods of dry weather, clay soil contracts and can cause ground movement, while wet conditions lead to expansion. This shrink-swell behaviour represents the primary cause of subsidence claims across England and is particularly relevant given the presence of mature trees and hedgerows throughout the rural landscape. Our inspectors assess tree proximity, soil type indicators, and any existing movement cracks when evaluating structural stability. Properties along Coate Road and The Row have notable trees in their gardens that warrant careful assessment.

The village sits within the Vale of Pewsey, an Area of Outstanding Natural Beauty, which brings additional planning considerations for property owners. Properties may be subject to restrictive planning controls, particularly those with listed building status. Wiltshire Council administers planning in this area, and permitted development rights may be more limited than in other parts of the country. Our surveyors understand these constraints and can identify any potential planning issues during our inspection.

• Late 17th Century farmhouses
• Georgian country houses
• Grade II listed properties
• Traditional stone and brick cottages
• Thatched roof buildings

Properties in Stanton St Bernard face several recurring issues that our surveyors regularly identify during inspections. Thatched roofs, while visually distinctive and characteristic of the Wiltshire countryside, require specialist maintenance and can develop problems with reed deterioration, ridge movement, and pointing failure. These roofs also present fire risks and may contain outdated electrical installations that require upgrading to current standards. We've inspected several thatched properties in the village and understand the maintenance requirements specific to this roofing type.

Timber defects represent another common finding in historic local properties. Oak and elm timber frames, common in buildings from the late 17th and 18th centuries, can suffer from woodworm infestation, wet rot, and dry rot if moisture enters the building envelope. Our inspectors probe timber elements and assess for signs of active decay, providing you with a clear picture of any remedial work needed. We use moisture meters to identify areas of elevated moisture that may indicate ongoing decay processes.

Given the traditional construction methods used in the village, damp issues frequently appear in survey reports. Rising damp affects solid wall properties without damp-proof courses, while penetrating damp may result from damaged roof coverings, failing gutters, or degraded pointing to stonework. Understanding the difference between these damp types and their appropriate remedies helps priorityise any necessary repairs. Many historic properties in the village have had past damp treatment, and we assess whether these treatments remain effective.

Properties in the village have historically used oil-fired central heating, with some conversions to LPG or electric systems in more recent years. Drainage arrangements vary between properties, with some using private septic tanks or treatment plants rather than mains sewage. These services receive attention during our survey, with particular focus on septic tank maintenance records where applicable. We note the location of septic tanks and their proximity to the property and water courses.

• Thatched roof deterioration
• Timber rot and woodworm
• Rising and penetrating damp
• Structural movement and cracking
• Outdated electrical systems
• Inefficient heating installations

The local landscape around Stanton St Bernard features characteristic chalk downland geology with overlaying clay deposits in lower-lying areas. Properties situated near the seasonal watercourse known as a winterbourne may face different ground conditions than those on higher ground. The winterbourne, which flows during winter months but dries in summer, indicates underlying chalk aquifers and variable soil conditions that can affect foundation performance. We've surveyed properties near this winterbourne and understand the implications for ground conditions.

Our surveyors assess external ground conditions as part of the inspection, noting any visible signs of movement such as cracking to external walls, uneven floor levels, or door and window sticking. While some minor settlement is normal in older properties, significant movement patterns may indicate ongoing subsidence or heave issues that could require specialist investigation. The proximity of trees to buildings also warrants careful evaluation given the clay soil shrink-swell potential. We measure distances from trees to the property and assess the species, as certain trees have more significant root systems that can affect foundations.

The clay soil shrink-swell risk affects a significant portion of properties in this area. During dry spells, the clay contracts and can cause foundations to move, while wet conditions lead to expansion. This cyclical movement can manifest as cracking in walls, particularly around window and door openings. Our inspectors document any existing cracking, measure crack widths, and assess whether movement appears to be active or historical. Properties with mature trees, including those along The Row and Church Walk, receive particular attention in this regard.

Drainage arrangements vary between properties, with some using private septic tanks or treatment plants rather than mains sewage. These services receive attention during our survey, with particular focus on septic tank maintenance records where applicable. We inspect inspection chambers where accessible and note the condition of drainage runs.
