RICS Level 3 Building Survey in Longburton

Longburton's housing stock presents unique challenges that make a RICS Level 3 Survey particularly valuable. The village features numerous properties built before 1900, constructed with solid walls, traditional timber floors, and original roofing materials that are now reaching the end of their natural lifespan. These older construction methods, while historically appropriate, can develop issues that only a thorough structural survey will uncover. The age of properties in Longburton, with many constructed in the Victorian and Edwardian periods, means that original features are now showing signs of wear that require professional assessment.

The local geology in this part of Dorset presents specific considerations for property buyers. The Jurassic formations underlying Longburton include clay-rich soils that can experience shrink-swell behaviour during periods of drought followed by heavy rainfall. This ground movement can cause subsidence or structural movement in properties, particularly those with shallow foundations typical of the Victorian and Edwardian eras. Our inspectors are trained to recognise the signs of such movement, including cracking patterns and door alignment issues. The Forest Marble and Cornbrash formations in this area are known to contain limestone and clay deposits that can affect foundation performance.

Additionally, many areas of Longburton face a medium to high risk of surface water flooding, which can lead to damp problems and damage to ground-floor structures. While the risk from rivers and the sea remains very low, surface water flooding during heavy rainfall events can affect low-lying areas of the village. The combination of these environmental factors with the age of the local housing stock means that a comprehensive survey is essential for any prospective buyer in this area. We specifically assess drainage around properties and check for evidence of previous water ingress.

The village falls within a Conservation Area, which means many properties are subject to additional planning constraints. Any potential buyer should be aware that alterations to listed buildings or properties within the Conservation Area require consent from Dorset Council. Our surveys highlight these considerations, ensuring you understand the full implications of your purchase before committing funds. We identify any work that might require listed building consent and explain the associated responsibilities.

• Solid wall construction
• Traditional timber roofing
• Clay-based ground conditions
• Period property defects
• Conservation area considerations

Based on our experience surveying properties throughout Dorset, we regularly identify several common issues in Longburton homes. Damp problems are particularly prevalent in older properties, whether rising damp due to missing or failed damp-proof courses, or penetrating damp caused by weathered pointing, damaged flashings, or failed gutters. The traditional construction methods used in Longburton's period properties often lack the moisture resistance built into modern buildings, making damp assessment a crucial part of any survey. We use moisture meters and thermal imaging where appropriate to identify damp issues that might not be visible to the naked eye.

Timber defects represent another significant concern in this area. The original timber floor joists, roof rafters, and structural beams in older properties can suffer from rot, woodworm infestation, or fungal decay. These issues often remain hidden until they become severe, which is why our inspectors carefully examine all accessible timber elements and probe where necessary to assess their structural integrity. We also check for signs of past timber treatment and any previous infestation that might have been treated but could recur. In properties with original timber floors, we assess whether the boards show signs of movement or decay that might affect their structural performance.

Roofing issues are extremely common in Longburton's older properties. Original slate and tile roofs often exceed their expected lifespan, with slipped tiles, degraded mortar, and damaged leadwork allowing water ingress. Our surveyors inspect the roof structure from within the loft space, examining the condition of rafters, purlins, and any strutting or support elements. We also assess the condition of chimneys, which are a frequent source of problems in period properties. Many Victorian and Edwardian properties in Longburton feature decorative chimney stacks that may have suffered from frost damage or cracked flashings.

Structural movement related to the local clay soils is something we specifically look for during our inspections. The shrink-swell behaviour of clay beneath foundations can cause characteristic cracking patterns in walls, particularly where properties have shallow footings typical of their era. We examine internal and external walls for signs of movement, checking door and window frames for alignment issues that might indicate structural problems. Where we identify potential concerns, we recommend further investigation by a structural engineer before you proceed with your purchase.
