RICS Level 3 Building Survey in Kinnerley

Kinnerley's housing stock presents unique challenges that make a Level 3 Survey particularly valuable. With 74.1% of properties being detached homes and many dating back to the 18th and 19th centuries, the village contains a significant proportion of older properties that require careful inspection. Our surveyors understand the construction methods typical of this area, from the red brick walls common throughout Kinnerley to the timber-framed properties that appear throughout the Conservation Area. Many homes in the village centre, including buildings like Cross Keys Public House with its cruck construction, represent traditional building methods that differ substantially from modern construction.

The geology of Kinnerley presents specific concerns for property buyers. The underlying boulder clay and gravels create potential shrink-swell risks, where clay soils expand and contract with moisture changes, potentially causing foundation movement. This is particularly relevant given Shropshire's variable climate, with periods of drought followed by heavy rainfall. Our inspectors specifically assess signs of subsidence, heave, and other ground movement that could affect the long-term stability of properties in this area. We examine walls for cracking, check door and window operation for binding, and look for other indicators of foundation movement that might not be apparent to untrained eyes.

Flooding has historically affected large parts of Kinnerley Parish, with the Environment Agency working with the Kinnerley Parish Council Flood Protection Working Group to address risks in the Severn/Vyrnwy catchment. Properties in certain locations may have been affected by surface water flooding, which can cause significant dampness and structural issues. A Level 3 Survey includes assessment of flood risk indicators and previous water damage that might not be apparent to the untrained eye. We check for water staining, damp metre readings, and evidence of previous flood damage that could indicate ongoing issues.

Kinnerley's Conservation Area, designated in July 2016, encompasses the historic village centre including properties around the Church of St Mary, The Old Vicarage, and numerous listed cottages and farm buildings. Properties within this area are subject to additional planning controls, and our surveyors understand these restrictions. When assessing a listed building, we can identify any works that may have been carried out without proper consents, which could complicate future renovations. The special architectural and historic interest of these buildings requires a detailed understanding of traditional construction methods and materials.

• Identify structural movement and subsidence risk
• Assess flood damage and damp issues
• Evaluate timber-framed construction common in listed buildings
• Check roof condition on older slate-roofed properties
• Review foundations on properties with shallow or no footings
• Identify potential listed building consent issues

Our experience surveying properties throughout Kinnerley and the surrounding SY10 area reveals several recurring themes. Dampness is perhaps the most common issue, particularly in older properties with solid walls. Unlike modern cavity-wall construction, these traditional buildings rely on their solid construction and breathable materials to manage moisture. When modern cement-based renders or non-breathable paints have been applied, trapped moisture can lead to penetrating damp and deterioration of timber elements. Our surveyors use moisture metres to identify areas of concern and can recommend appropriate remediation that maintains the breathability traditional buildings require.

Roof problems feature prominently in our Kinnerley surveys. Many older properties retain their original low-pitched slate roofs, which may have exceeded their expected lifespan. Missing or slipped tiles, damaged flashing around chimneys, and deteriorated felt underlay are all commonly identified. Additionally, we often find signs of roof spread where the weight of traditional slate has caused walls to bow outwards over time, particularly where original timber rafters have been softened by damp or insect attack. Properties throughout the village, from cottages near the village hall to larger farmhouses, frequently require roof-related recommendations.

Timber decay and infestation represent another significant concern in Kinnerley's older housing stock. Properties with timber framing, such as the historic Cross Keys Public House with its cruck construction, require specialist assessment. Wet rot and dry rot can affect any timber element that experiences prolonged moisture exposure, while woodworm infestation can weaken structural timbers. Our surveyors know exactly what to look for and can identify early signs that might be missed by less experienced inspectors. We specifically examine structural timbers in roof spaces, floor joists, and any exposed timber framing.

The local geology creates additional challenges for Kinnerley property owners. The boulder clay underlying much of the parish is susceptible to shrink-swell behaviour, where the clay expands and contracts with moisture changes. This can cause foundations to move over time, leading to cracking and structural issues. Properties with trees nearby are particularly vulnerable, as tree roots can draw moisture from the soil, exacerbating shrink-swell effects during dry periods. Our surveyors assess the condition of foundations and look for signs of movement that might indicate geotechnical concerns.

• penetrating damp from failed brickwork or render
• rising damp from defective damp-proof courses
• condensation in poorly ventilated properties
• roof spread in properties with heavy slate coverings
• timber decay in structurally significant elements
• foundation movement from clay shrink-swell
• defective drainage causing saturation of foundations
