RICS Level 3 Survey in Alston CA9 3

The CA9 3 area encompasses Alston, one of the highest market towns in England, sitting at approximately 1,000 feet above sea level in the heart of the North Pennines Area of Outstanding Natural Beauty. This rural location means the housing stock predominantly consists of traditional stone-built properties, many dating back to the 18th and 19th centuries when lead mining was the primary industry. These older properties, while full of character, often present unique structural challenges that only a detailed Level 3 Survey can uncover. Our inspectors understand the specific construction methods used in this region and know exactly what to look for when assessing a property's condition.

The historic nature of Alston means many properties fall within or adjacent to conservation areas, and a significant number are listed buildings. These designations bring additional considerations for maintenance and potential alterations. Our Level 3 Survey reports include specific advice on how listed building status or conservation area constraints might affect your future plans for the property, ensuring you enter into your purchase with full knowledge of any restrictions or requirements. We understand the Listed Building Act and can advise on what works may require Listed Building Consent from the local authority.

The local geology around Alston presents area-specific considerations that our surveyors take into account. The North Pennines region has a complex geology including limestone, sandstone, and shale, and the historic lead mining activity in the area means mining subsidence is a potential structural risk that must be considered. Our inspectors are familiar with these local factors and will investigate any signs of movement or subsidence that could affect the property's structural integrity. We specifically look for evidence of historic mining shafts, ground disturbance, and characteristic cracking patterns that might indicate mining-related movement.

Properties in this area also face challenges from the local climate. Being situated at altitude in the Pennines, Alston experiences harsher weather conditions than lower-lying areas, with greater exposure to wind, rain, and frost damage. This can accelerate deterioration of external fabric elements, particularly roofing materials and external render. Our surveys take account of these environmental factors when assessing the condition of the property.

• Traditional stone construction
• Conservation area properties
• Listed buildings
• Mining subsidence risk
• Older housing stock
• Rural drainage systems
• High altitude weather exposure

Properties in the CA9 3 area face several common issues that our Level 3 Surveys frequently identify. Given the traditional construction methods used in the region, damp penetration is one of the most prevalent problems, particularly in properties with solid walls rather than cavity wall construction. Our inspectors carefully assess damp levels throughout the property and identify the source of any moisture ingress, whether it's from rising damp, penetrating damp, or condensation issues. In properties with solid stone walls, we check the condition of any existing tanking or damp proof courses and advise on appropriate remediation.

Timber defects are another major consideration for properties in this area. The age of much of the housing stock means that timber joists, rafters, and structural elements may have been subject to decades of potential decay. Our surveyors examine all accessible timber for signs of rot, insect infestation, or structural weakness. In older properties, we pay particular attention to floor structures, roof trusses, and any timber in contact with external walls or exposed to damp conditions. The humid climate of the North Pennines can accelerate timber decay in properties with inadequate ventilation.

Roof problems feature prominently in our surveys of Alston properties. The traditional slate roofing common in the North Pennines can suffer from slipped or broken tiles, deteriorating mortar in ridge lines, and issues with flashings around chimneys and dormer windows. Given the exposed location of Alston, wind damage and storm damage are ongoing concerns, and our inspection will identify any current or potential future issues with the roofing system. We also assess the condition of chimneys, which are common on period properties and can pose structural risks if deteriorating.

Wall tie failure is a specific issue we encounter in properties that have cavity walls but were built before modern tying standards. While many Alston properties have solid walls, some mid-20th century extensions or conversions may have cavity wall construction. Our surveyors check for signs of corrosion in wall ties, which can cause bulging or separation of external wall leaves if left untreated.

Given the area's history of lead mining, we pay particular attention to signs of subsidence or ground movement. This includes checking for cracking patterns that might indicate mining-related activity, assessing whether properties have been subject to past ground stabilisation, and looking for evidence of mine entries or shafts in the vicinity. Where we identify concerns, we recommend appropriate specialist investigation.

• Damp penetration in solid wall properties
• Timber rot and insect damage
• Roof defects and slate deterioration
• Chimney stability issues
• Wall tie failure in cavity walls
• Foundation and subsidence concerns
• Mining-related ground movement
