RICS Level 3 Building Survey in L23 3

Our RICS Level 3 Building Survey provides an exhaustive examination of all accessible parts of the property. Our surveyor will assess the walls, roof, floors, doors, and windows, checking for signs of structural movement, damp ingress, timber decay, and roof condition. In L23 3, where Victorian and Edwardian properties dominate, we pay particular attention to the common issues that affect older construction, including deteriorating slate roofs, original timber windows requiring restoration, and solid walls prone to rising damp. We examine the condition of ridge tiles, valley gutters, and flashings, as these are frequent failure points on period properties.

The survey includes a thorough assessment of the property's foundations and substructure. Given the clay soil conditions throughout much of L23 3, our inspectors are trained to identify signs of subsidence, heave, or ground movement that could indicate foundation problems. We examine external walls for cracking patterns, check internal ceilings and walls for signs of movement, and assess the ground around the property for evidence of past or current subsidence. Our surveyors specifically look for diagonal cracks near windows and doors, which often indicate foundation movement on shrinkable clay soils.

Unlike a basic mortgage valuation, a Level 3 Survey provides specific recommendations for repairs and maintenance. The report will prioritise issues by severity, explain the likely cost implications of remedying defects, and provide guidance on whether further specialist investigations are required. For properties in conservation areas like Blundellsands Park, we also highlight any implications for listed building consent or conservation area restrictions that may affect future renovations. We note any building regulation compliance issues from previous extensions or loft conversions.

The predominant housing in L23 3 consists of Victorian and Edwardian properties built between 1880 and 1910. These homes were constructed with solid brick walls, traditional timber floors, and slate roofs, often with shallow foundations that may not meet current building standards. Our surveyors frequently encounter issues with original timber windows suffering from rot, slate tiles deteriorating with age, and solid walls lacking cavity insulation. The red brick construction common to the area, while visually appealing, can be particularly susceptible to frost damage and salt ingress in exposed locations.

The underlying clay soil throughout L23 3 presents a significant subsidence risk, particularly for properties with shallow foundations or large trees close to the building. During our surveys, we carefully examine walls for cracking patterns that might indicate foundation movement, check for signs of previous repair work, and assess the surrounding ground conditions. Properties near the coast may also face localised flooding issues during extreme weather events. The superficial geology of till (boulder clay) over Sherwood Sandstone means that moisture changes can cause the ground to shrink and swell, putting stress on traditional shallow foundations.

Many properties in the area have been modified over the years with extensions, loft conversions, and modernisations. Our Level 3 Survey assesses these alterations for structural soundness and checks whether appropriate building regulations approval was obtained. For properties in the Blundellsands Park Conservation Area, we note any conservation implications that might affect future improvement plans. We frequently find that older conversions may not meet current standards for thermal efficiency or structural adequacy.
