RICS Level 3 Building Survey in Forest Row RH18

Forest Row sits within the Wealden district, an area characterised by complex geology that directly impacts property foundations and structural integrity. The underlying Weald Clay formation presents a significant shrink-swell risk, meaning properties in RH18 can experience ground movement due to changes in moisture levels. This is particularly relevant for the substantial proportion of older properties in the area, many of which were built before modern foundation techniques were developed. Trees and vegetation common in this leafy village draw moisture from the clay soil, potentially causing foundation movement that manifests as cracking in walls.

The village contains a designated Conservation Area with numerous listed buildings, concentrated around the village centre and historic properties surrounding St. Stephen's Church. Properties in these areas often require more detailed inspection due to their age, traditional construction methods, and the stringent planning constraints that apply. Our surveyors are experienced in assessing historic properties and understand the specific issues that affect buildings constructed with traditional materials like solid brick walls, timber frames, and slate roofing. We also advise on any implications for future alterations under planning constraints.

Recent new-build developments from Thakeham at Ashdown Vale on London Road and Bramble Park on Priory Road offer modern housing stock, but even new properties benefit from professional inspection. While these homes come with NHBC guarantees, our Level 3 survey can identify any construction defects, issues with snagging, or problems that may have emerged since the properties were completed. With prices ranging from £450,000 to over £1,000,000 for these new homes, a survey represents a wise investment that could save tens of thousands in unexpected repair costs.

The Level 3 Survey provides an exhaustive assessment of your Forest Row property, examining all major structural elements and construction types found in the area. Our inspectors assess the condition of roofs, including pitched roofs common on older terraced and detached properties and flat roofs often found on extensions and modern apartments. We inspect roof structures, looking for signs of rot, insect damage, and inadequate support that could compromise the integrity of the entire building. In the roof space, we examine the condition of rafters, purlins, and any strutting that supports the structure.

Walls receive detailed attention, with our surveyors examining both external brickwork and internal plasterwork. In Forest Row's older properties, we look for signs of penetrating damp, which is a common issue in solid-walled buildings constructed before modern damp-proof courses were standard. We assess the condition of render and pointing on properties, particularly those in the Conservation Area where traditional lime mortar may have deteriorated over time. We also examine the integrity of any cavity walls in newer properties, checking for signs of bridging or insulation gaps.

The survey includes thorough assessment of floors, examining both solid concrete floors and suspended timber floors found in many RH18 properties. We check for signs of subsidence, unevenness, or rot in floor timbers. Our inspection covers joinery including windows and doors, assessing their condition, operation, and energy efficiency. We also examine the condition of porches, conservatories, and other extensions that are common additions to properties throughout Forest Row. For properties with outbuildings or garages, we include these in our assessment.

• Roof structure and covering
• Walls, damp-proofing, and render
• Floors and foundations
• Windows and doors
• Chimneys and breast stacks
• Garage and outbuildings
• Services (gas, electric, plumbing)
• Boundaries and exterior areas

Properties in Forest Row reflect multiple eras of construction, each with their own characteristic features and potential defects. The older housing stock, representing about 25.4% of properties built before 1919, typically features solid brick walls constructed with lime mortar, traditional timber-framed windows, and slate or clay tile roofing. These period properties often have shallow foundations that can be affected by ground movement, particularly on the clay soils that dominate the area. Understanding these construction methods is essential for accurate assessment of condition and identification of defects.

Properties constructed between 1919 and 1945 often feature improved construction standards with cavity walls becoming more common, though many still retain traditional features. The post-war period through to 1980 saw the development of new construction methods, with concrete tiles replacing slate and cavity wall construction becoming standard. These mid-century properties may have different defect profiles, including issues related to concrete deterioration or inadequate insulation that our surveyors know to look for.

Newer properties in developments like Ashdown Vale and Bramble Park represent modern construction techniques with timber frame or blockwork structures, engineered roof trusses, and high levels of insulation. While these properties generally meet current building regulations, our Level 3 survey can identify any issues with workmanship or materials that might not be covered by NHBC warranties. We also assess whether the property has been constructed in accordance with its planning approval, particularly important in this edge-of-Settlement location within the High Weald.

Given the age profile of housing in Forest Row, our surveys frequently identify issues related to the age of the construction. Properties built before 1919, which represent approximately 25.4% of the local housing stock, commonly show signs of aging in their original features. This includes deteriorating roof coverings where slate or clay tiles have reached the end of their service life, original timber windows that have warped or rotted, and outdated electrical wiring that does not meet current regulations. Many of these properties also lack modern damp-proof courses, making them susceptible to rising damp.

Damp problems feature prominently in our survey findings for older properties. Rising damp affects many period buildings, particularly where original damp-proof courses have failed or were never installed. Penetrating damp results from damaged roof coverings, deteriorated pointing, or failing render. In properties with solid walls, which are common throughout RH18, condensation can also be an issue, particularly in poorly ventilated bathrooms and kitchens. Our surveyors use thermal imaging equipment where appropriate to identify areas of moisture and inadequate insulation.

The local geology creates specific challenges that our surveyors specifically look for when inspecting Forest Row properties. Clay shrinkage subsidence affects buildings on the Weald Clay formation, with trees and shrubs drawing moisture from the ground causing the clay to contract. This manifests as characteristic cracking in walls, typically diagonal cracks extending from windows and doors. Our surveyors examine foundations, external walls, and internal finishes for evidence of this type of movement. Properties with large trees close to the building are particularly at risk, especially those along Hartfield Road and the lanes leading towards Coleman's Hatch.

Flood risk from the River Medway and its tributaries affects properties in low-lying areas of RH18. Our surveyors assess flood resilience measures, examine signs of previous flooding, and check the condition of drainage systems. Surface water flooding can also occur in areas where drainage infrastructure is insufficient, particularly during periods of heavy rainfall. Properties near the river or in areas known for surface water issues receive particular attention during our inspection.
