RICS Level 3 Building Survey in Brompton Regis

Properties in Brompton Regis differ significantly from modern housing stock, and this has important implications for your survey. The village is characterised by traditional construction methods that were common throughout Somerset and Exmoor generations ago. Exposed stone walls, often constructed using local stone from the Pilton Beds geological formation, feature prominently throughout the area. These grey mudstones and siltstones with calcareous sandstones have shaped the distinctive character of buildings in the parish, but they also present specific challenges that require experienced surveyor assessment. We have examined hundreds of these traditional stone properties and understand how the local geology affects building performance.

The roofing materials in Brompton Regis predominantly consist of natural slate, which has served properties well for generations but requires ongoing maintenance and occasional replacement. Many properties also feature traditional lime mortar pointing rather than modern cement, and this distinction is crucial for proper maintenance. Using inappropriate modern materials on historic buildings can actually cause more harm than good, trapping moisture and accelerating deterioration. Our surveyors understand these traditional building methods and will identify any instances where previous owners may have used unsuitable materials that require remediation. We commonly find cement mortar that has been incorrectly applied to replace failing lime pointing, which causes moisture to become trapped within the stone walls.

The rural nature of Brompton Regis means that many properties have remained in the same families for generations, with limited modern renovation work undertaken. While this preservation of character is appealing, it also means that some properties may have hidden defects that have developed gradually over decades. Our thorough Level 3 Survey examines all accessible areas of the property, from roof spaces to underfloor voids, providing you with a complete picture of the building's condition. We lift access covers, enter loft spaces, and examine outbuildings where safe access permits.

Properties in this area often have no modern damp proof course, and this is particularly relevant for properties with solid ground floors. Our surveyors test walls for moisture using professional equipment and assess whether rising damp is present or whether the property relies on traditional wall construction that manages moisture naturally. We examine the external ground levels relative to internal floor levels to determine whether damp proofing is adequate or whether the property may be at risk from penetrating dampness.

• Natural slate roofing
• Lime mortar pointing
• Period windows and joinery
• Historic floor structures

Our experience surveying properties throughout the Exmoor National Park area has identified several recurring issues that buyers should be aware of. Damp and condensation problems feature prominently in many traditional stone-built properties, particularly where modern improvements have been made without adequate consideration for ventilation requirements. Properties that have had new windows installed or solid wall insulation added without proper vapour control can experience significant moisture-related issues that manifest as black mould, peeling decoration, and deterioration of building fabrics. We have surveyed properties throughout the village where condensation staining is visible on internal walls, particularly in kitchens and bathrooms where moisture generation is highest.

Roof problems represent another common finding in Brompton Regis surveys. The natural slate roofs that characterise the area, while visually appealing and durable, require periodic maintenance. Slipped slates, failing flashings around chimneys and valleys, and deterioration of ridge tiles all feature regularly in our survey reports. Additionally, the timber structures within roof spaces can suffer from decay, particularly where ventilation has been compromised or where there has been historic water ingress. We inspect all accessible roof spaces and will report on the condition of battens, rafters, and any visible timber sizing.

Structural movement affects many older properties in the area, manifesting as cracking in walls that may be visible internally or externally. While some movement is normal in buildings of any significant age, our surveyors assess whether the movement is active, static, or the result of past issues that have now stabilised. We examine the pattern and nature of cracks to determine their likely cause and whether they require structural engineer involvement. In our experience, properties built on the slopes leading down to the river have occasionally shown signs of minor movement related to ground conditions, though this is rarely serious.

Defective lead flashings are a particularly common issue in Brompton Regis, given the age and traditional construction of many properties. Lead flashings around chimneys, at roof verges, and where slate roofs meet walls can deteriorate over time, allowing water penetration. We carefully examine all flashing details during our inspection and will report on any signs of deterioration, poor installation, or missing sections. Additionally, timber decay in window frames is prevalent, as many original windows have survived for decades without proper maintenance or repainting.

• Rising damp in solid floor constructions
• Timber rot in window frames
• Defective lead flashings
• Cracking from foundation movement
• Surface water flooding risk

While much of Brompton Regis falls within Flood Zone 1, indicating a low probability of river flooding, prospective buyers should be aware of surface water flooding risks that affect certain locations within the parish. The rural setting, with watercourses running through the valley and proximity to streams that feed into larger river systems, means that flash flooding from heavy rainfall can occur in low-lying areas. Properties located near the river or streams that traverse the village may be at higher risk, particularly those with gardens that slope towards watercourses. We have surveyed properties in similar Exmoor villages where surface water has entered ground floor accommodation during periods of heavy rainfall.

Our surveyors will assess the property's flood risk during the inspection and note any visible evidence of previous flooding or water damage. We will examine the drainage arrangements, the position of the property relative to watercourses, and any existing flood mitigation measures. This information is included in your survey report and is particularly important for properties in lower-lying parts of the village or those with large gardens that slope towards watercourses. We look for water staining, tide marks, and other indicators that may suggest historic flooding events.

The Environment Agency flood maps should be consulted for specific site risk assessment, and we recommend that buyers satisfy themselves regarding flood risk before completing a purchase. Properties in certain locations within Brompton Regis may require specific insurance arrangements or additional flood resilience measures. Some properties in the valley bottom areas may face higher premiums for buildings insurance, and this cost should be factored into your overall purchase budget. We can advise on simple measures that can reduce flood risk, such as non-return valves on drainage and property level flood protection.
