RICS Level 3 Building Survey in Duns Tew

The housing stock in Duns Tew presents specific challenges that only a RICS Level 3 Survey can thoroughly address. The village's geology, primarily characterised by Oxford Clay Formation and Jurassic limestone, creates potential for clay shrink-swell activity. This occurs when mature trees draw moisture from the soil, causing it to contract and expand. Properties with shallow foundations or those situated close to established trees are particularly vulnerable to subsidence or heave movements. Our surveyors know exactly where to look for the signs of this type of ground movement, examining window and door openings for sticking, cracks in walls, and differences in floor levels that may indicate structural stress.

Many properties in Duns Tew feature traditional solid wall construction using local Hornton stone or limestone, often with lime mortar pointing. These traditional materials require specific expertise to assess correctly. Common defects we encounter include penetrating damp through failed mortar joints, deterioration of stonework through frost action, and rot in timber elements such as floor joists and roof structures. The age of much of the housing stock means that original features may have been modified over the years, sometimes using inappropriate materials that can cause long-term damage. Our team has the expertise to identify where modern cement-based mortars have been applied to historic lime mortar joints, which can trap moisture and accelerate stone deterioration.

As a designated Conservation Area with numerous listed buildings, including the Grade I listed Church of St Mary Magdalene, Duns Tew properties often face additional considerations. Alterations to historic buildings may have been carried out without proper consent, or may have used modern materials that are incompatible with traditional construction. Our surveyors will identify these issues and advise on the implications for your intended purchase, noting any potential conflicts with planning requirements or Listed Building Consent that may affect your renovation plans.

The village's location between Bicester, Banbury, and Oxford means many buyers are commuters seeking a rural lifestyle while maintaining access to employment centres. This demand has supported property values, but it also means that properties may have been subject to various modifications over the years as buyers adapted homes for modern living. Our detailed survey will uncover any previous alterations that might not meet current building regulations or that could pose structural risks.

Our experience surveying properties throughout the Duns Tew area has identified several recurring issues that buyers should be aware of. Damp problems are particularly common in older stone-built properties, where solid walls lack the cavity construction found in modern buildings. Rising damp can occur where existing damp-proof courses have failed or were never installed, while penetrating damp often affects walls exposed to prevailing westerly winds and driving rain from the Atlantic. Our inspectors use professional moisture meters to identify the extent of any dampness and determine whether it is active or historic.

Timber defects represent another significant concern in this area. Wet rot and dry rot can affect timber floor joists, roof timbers, and window frames, particularly in properties with poor ventilation or existing damp issues. In older properties, we often find that original softwood timbers have been affected by decades of minor moisture exposure, even whereDecorator's param have been applied. Woodworm infestations, while not uncommon, are typically treatable but require professional assessment to determine the extent of any damage and whether structural timbers have been compromised.

Roofing issues on traditional slate and tile roofs are frequently identified during our surveys. Slipped tiles, damaged leadwork around chimneys, and deteriorating mortar pointing can all allow water ingress that leads to internal damage. Many properties in Duns Tew feature clay tiles imported from the Midlands during the Victorian era, and finding matching replacements can be challenging and expensive. Chimney stacks, often a prominent feature on Duns Tew properties due to the historic reliance on open fires, commonly show signs of weathering including spalling stonework, damaged flashings, and deteriorating mortar joints.

Structural movement is another issue we regularly encounter in the village. The combination of clay soils and mature trees means that properties may experience differential settlement as soils shrink during dry summers and expand during wet winters. Our surveyors are trained to identify the signs of this movement, including crack patterns in walls, differences in floor levels, and doors and windows that no longer close properly. We assess whether any movement is active and whether it requires structural engineer involvement.

The underlying geology of Duns Tew plays a significant role in the condition of properties in the village. The combination of Oxford Clay Formation and Jurassic limestone creates conditions that can affect building foundations. Clay soils are particularly susceptible to volume changes with variations in moisture content, and the presence of mature trees nearby can exacerbate this through seasonal drying cycles. We have surveyed properties where oak and ash trees located within neighbouring fields have caused significant ground movement, leading to structural issues that required underpinning or other remedial works.

Surface water flooding represents a practical consideration for some properties in Duns Tew. While river and sea flood risk is very low, low-lying areas and depressions in the local topography can experience water accumulation during periods of heavy rainfall. The village sits on slightly elevated ground in places, but certain properties near the stream that runs through the lower part of the village may be affected. Our surveyors will assess the drainage characteristics of the property and its surroundings, noting any evidence of previous flooding or water damage that may not be immediately apparent.

The local authority, Cherwell District Council, maintains strict planning policies for the Duns Tew Conservation Area. Any significant renovations or extensions to properties in the village will likely require planning permission and possibly Listed Building Consent. Understanding the condition of a property before purchase is therefore essential, as restoration costs for historic buildings can be substantial. Our survey report will help you understand what work may be needed and what permissions may be required, allowing you to factor these costs into your purchase decision.

The predominant construction methods in Duns Tew reflect the village's agricultural heritage and local geology. Many properties were built using locally sourced Hornton stone, a type of ironstone that was quarried from shallow pits in the surrounding countryside. This stone is relatively hard-wearing but can be susceptible to frost damage when saturated. Lime mortar was traditionally used for pointing, allowing the walls to breathe, and our surveyors can identify where inappropriate modern cement-based mortars have been applied, which can cause moisture to be trapped and lead to accelerated stone decay.
