RICS Level 3 Survey Eye and Dunsden

The housing stock in Eye and Dunsden presents particular challenges that make a RICS Level 3 Survey essential for any prospective buyer. The parish contains a significant number of properties constructed before 1900, many featuring traditional timber-framed construction that requires specialist knowledge to assess properly. These older properties often have solid walls rather than modern cavity construction, which behaves differently and can suffer from distinct defects such as rising damp, timber decay, and movement in the structural framework. A standard Level 2 survey may not adequately identify the specific issues affecting these historic buildings.

The local geology adds another layer of complexity to property assessments in this area. Eye and Dunsden sits on chalk overlain by extensive patches of river gravel, with higher ground around Bolt's Cross and Kingwood capped by clay-with-flints. Properties built on the clay-with-flints deposits are at risk of shrink-swell movement, where the clay expands and contracts with moisture changes, potentially causing structural damage to foundations and walls. Our surveyors know to look for signs of this movement in properties throughout the parish, particularly in the elevated areas around the crossroads at Bolt's Cross and along the road towards Kingwood.

The southern part of the parish, particularly around Sonning Eye and the River Thames floodplain, faces significant flood risk. Properties in this area fall within Flood Zone 3B, which includes functional floodplains that have historically experienced flooding. The area has seen multiple flood events over the years, with properties along the river corridor particularly vulnerable. A detailed RICS Level 3 Survey will assess any previous flood damage, damp penetration, and the effectiveness of any existing flood mitigation measures. This information is crucial for properties in the southern reaches of the parish around Sonning Eye and the areas bordering the Thames.

Properties in Eye and Dunsden are also subject to strict planning constraints due to the conservation areas and numerous listed buildings throughout the parish. The Sonning Eye conservation area covers much of the southern part of the parish, while the historic heart of Dunsden Green contains several listed buildings that are protected for their architectural and historical significance. Our surveyors understand these constraints and will highlight any issues that may affect future renovation plans or listed building consent requirements.

• Timber-framed construction assessment
• Flood risk evaluation
• Clay subsidence monitoring
• Historic building condition reports
• Conservation area compliance
• Listed building considerations

Our experience surveying properties throughout the Eye and Dunsden area has identified several recurring issues that buyers should be aware of. Damp and timber decay is particularly prevalent in the older timber-framed cottages and properties with solid walls. These buildings were constructed before modern damp-proof courses and rely on natural ventilation to manage moisture levels. Modern heating and insulation improvements can sometimes trap moisture and cause problems if not properly implemented. Our surveyors use moisture meters and thermal imaging equipment to identify areas of damp that may not be visible to the naked eye.

Structural movement is another common finding in properties across the parish. This can result from the clay-with-flints geology causing shrink-swell issues, or from historic timber frames settling over time. While some movement may be historic and stable, our surveyors are trained to distinguish between harmless settlement and active structural problems that require further investigation or remedial works. We measure crack widths and monitor patterns of movement to determine whether the issues are live problems or historic features that have remained stable for years.

Roof and chimney defects are frequently identified in the older properties in Eye and Dunsden. Traditional clay tile roofs over 100 years old may have deteriorated tiles, damaged ridge pointing, or degraded lead flashings. Chimneys on period properties often show signs of corrosion to flues, damaged brickwork, or inadequate parapet detailing that can lead to water penetration. These defects can be expensive to repair and may not be visible from ground level, which is why our detailed inspection is so valuable. Our surveyors will access the roof wherever it is safe to do so, and use drones for higher properties where appropriate.

Properties in the southern flood risk areas of the parish may show evidence of previous water ingress, including tide marks, damaged plaster, or replaced floor coverings. The proximity to the River Thames means that properties in Sonning Eye and the surrounding floodplain have historically been affected by high water levels. Our surveyors will investigate whether appropriate flood resilience measures are in place and whether any past flooding has caused lasting damage to the structure or fabric of the building. We will also advise on any flood mitigation works that may have been undertaken and their effectiveness.
