RICS Level 3 Building Survey in Gisburn Forest

The properties in and around Gisburn Forest present unique challenges that make a RICS Level 3 Survey particularly valuable. The local geology consists of Carboniferous-age sedimentary rocks, including Millstone Grit, shales, and limestones, overlaid with glacial till and extensive upland peat. This clay-rich subsoil creates a potential shrink-swell risk, meaning properties may experience movement over time, particularly where moisture levels fluctuate significantly. Our surveyors understand how these geological conditions affect buildings and know what to look for when inspecting properties in this area.

Many of the older properties in this area were constructed using solid stone wall construction without modern cavity wall insulation or damp-proof membranes. The wet, upland climate of the Forest of Bowland means that damp penetration is a common concern, especially where original damp-proof courses have failed or were never installed. Our surveyors pay particular attention to these issues when inspecting properties in the Gisburn Forest area, using thermal imaging and moisture meters to identify problem areas that might not be visible to the untrained eye.

The landscape around Gisburn Forest is characterized by steep valleys and watercourses feeding into Stocks Reservoir. Properties located in valley bottoms face a risk of surface water flooding following heavy rainfall, and our surveys include assessment of flood risk and any historical evidence of water ingress. Additionally, the exposed nature of the upland terrain means that roofs and chimneys are vulnerable to storm damage, with missing or slipped slates a frequent finding on older properties throughout the area.

We have surveyed numerous properties in the Gisburn Forest area and consistently find issues related to the challenging environmental conditions. The combination of high rainfall, exposed positions, and aging traditional construction means that thorough surveying is essential for any prospective buyer. Our detailed RICS Level 3 Survey provides the comprehensive assessment needed to make an informed decision about your property purchase.

• Ground movement and subsidence risk
• Damp and condensation issues
• Roof and chimney condition
• Flood risk assessment
• Stone wall integrity
• Traditional construction methods

Properties in the Gisburn Forest area reflect the traditional building methods that have been used in this part of Lancashire for centuries. The predominant construction type consists of solid stone walls, typically built using local gritstone or sandstone quarried from the surrounding hillsides. These walls are generally thick, often measuring 450mm or more, and were constructed using lime-based mortars rather than modern cement mixes. Understanding these traditional methods is essential for accurate assessment, as the properties require different evaluation criteria compared to modern cavity-wall constructions.

Roof construction in the area typically features traditional cut timber rafters with slate or stone tile coverings. Many properties have traditional couple roofs, while others feature more complex arrangements with purlins and ridge beams. The roofing materials predominantly consist of natural slate, often sourced from local quarries, though some properties may have more recent concrete tile coverings. Our surveyors inspect these roof structures carefully, as the age of many properties means that timber decay, especially in roof void areas, is a common concern.

Traditional features commonly found in Gisburn Forest properties include large stone chimneys with pot breasts, stone-flagged floors, and exposed ceiling beams. Many properties also have outbuildings or attached barns that may have been converted or may form part of the original farmstead. When surveying these properties, we assess not only the main dwelling but also any attached or detached structures that form part of the property sale. The conversion of agricultural buildings into residential use is common in this area, and our surveyors are experienced in assessing the quality of such conversions.

The foundation types found in properties throughout Gisburn Forest vary considerably. Some older properties were built directly onto the ground with minimal foundation detail, while others feature shallow stone footings. The presence of clay-rich soils means that foundations may be susceptible to movement, particularly where trees or hedgerows are located close to buildings. Our inspectors examine foundation walls carefully for signs of cracking or movement that might indicate subsidence issues, which are particularly relevant in this area due to the underlying geology.

Based on our experience surveying properties throughout the Ribble Valley and Forest of Bowland area, several recurring issues affect buildings in the Gisburn Forest locality. The first and most prevalent is damp penetration. Traditional stone-built properties in this area were often constructed without effective damp-proof courses, and the high rainfall experienced in the upland areas of Lancashire means that moisture can penetrate walls over time. Our surveyors use moisture meters and thermal imaging equipment to identify areas of damp and assess the effectiveness of any existing damp-proofing. We frequently find that external ground levels have risen over the years, bridging what little damp-proofing may have been originally installed.

The second common issue relates to the condition of roofs and chimneys. Many properties in this area feature traditional slate roofs, which have a long lifespan but require regular maintenance. Storm damage is a particular concern, with high winds able to dislodge slates and cause damage to ridge tiles. Chimneys on older properties are often in poor condition, with deteriorating brickwork, damaged flashings, and unsafe pot breasts all frequently identified during surveys. The exposed position of many properties means that roof defects can lead to rapid water ingress and extensive damage to internal finishes.

Third, we frequently find evidence of structural movement in properties built on the clay-heavy soils characteristic of this area. While some movement is normal in older buildings, significant cracks or signs of ongoing movement require careful assessment. Our surveyors are trained to identify the signs of subsidence, settlement, or movement caused by trees or changing ground conditions, which is particularly relevant in rural areas where large hedgerow trees may be growing close to buildings. The presence of shrink-swell clay in the subsoil means that properties with trees nearby are at particular risk.

A fourth issue that we commonly encounter relates to the condition of traditional joinery and windows. Many properties in Gisburn Forest still have original single-glazed timber windows that may be in poor condition or have rotten sections. The wet climate accelerates timber decay, and we often find that window frames, door frames, and external joinery require attention. Our surveyors thoroughly inspect all joinery elements and note any defects that will require maintenance or replacement. These issues, while not necessarily structural, can represent significant maintenance costs for prospective buyers.
