RICS Level 3 Survey Bath and North East Somerset

The housing stock in Bath and North East Somerset differs significantly from newer developments elsewhere in the UK. With 78.2% of households living in houses or bungalows and a substantial proportion built before 1919, many properties feature traditional construction methods that require specialist knowledge to assess properly. Our Level 3 Survey goes beyond the visual inspection of a basic survey, investigating structural elements, identifying hidden defects, and assessing the condition of key building components that other surveys might miss. We examine how solid wall constructions function differently from modern cavity walls and identify issues caused by inappropriate modern repairs.

The region's geology creates specific challenges for property owners that our inspectors are trained to recognise. Clay-rich soils, particularly the Lias Clays underlying much of the area around Bath and the Dundry Hill slopes, are susceptible to shrink-swell movement, especially near trees and with changing moisture levels. Historical coal mining in the southern parts around Radstock and Midsomer Norton, along with extensive Bath Stone quarrying beneath Bath itself - particularly in the Combe Down area where stabilisation programmes have been required - means some properties face potential subsidence risks. Our inspectors are trained to identify signs of these issues and assess their severity, checking for indicators such as cracking patterns, door and window binding, and uneven floor levels.

Flood risk is another significant consideration in this area, with the River Avon, River Chew, and numerous tributaries including Midford Brook, Cam Brook, and Wellow Brook flowing through populated areas. Properties in Bath, Keynsham, Midsomer Norton, Radstock, and Chew Magna have experienced significant flooding historically, with the 2012 Chew Magna flooding being particularly notable. An area upstream of Keynsham Weir on the River Avon is tidally influenced and may be susceptible to tidal flooding, with this risk potentially increasing due to sea level rise. Our survey includes assessment of flood risk indicators and any existing flood resistance measures, helping you understand the true condition of properties in affected locations.

The architecture of Bath and North East Somerset is significantly influenced by its local geology and historical building practices. The predominant building material, particularly in the city of Bath, is the distinctive golden-coloured Bath Stone, a Middle Jurassic oolitic limestone that defines the city's Georgian architecture from the 18th and 19th centuries. Beyond Bath, traditional buildings in areas like the former Wansdyke district often feature walls of sandstone or limestone, with Brown Pennant Sandstone historically used in central parts of the district including Farrington Gurney, Clutton, Pensford, and Publow. White Lias limestone rubble stone walls are also present in certain villages such as Corston.

For roofing, limestone tiles are common, especially in the east of the district around Bath villages like Freshford, Hinton Charterhouse, and Wellow. Thatch was once a common roof material but is now rare. Clay tiles, often sourced historically from Bridgwater, became prevalent from the late 18th to late 19th centuries, while Welsh slate became widely available with the advent of canals and railways. The council encourages the use of traditional natural materials and lime-based mortar for repairs and new works on historic buildings, and our inspectors understand how to identify problems caused by inappropriate modern materials such as cementitious mortar on historic lime-pointed walls.

Properties built before 1919 often have solid walls that function differently from modern cavity wall constructions. These traditional buildings rely on their ability to breathe, and modern refurbishments that have reduced natural airflow can lead to damp problems, condensation, and timber decay. Our inspectors understand these building methods and can identify issues caused by inappropriate modern repairs, such as non-breathable paints that trap moisture or solid wall insulation installed without adequate ventilation. For listed buildings, any work affecting their character requires Listed Building Consent, and our survey will highlight any matters that may affect your ability to obtain such consent.

Our experience surveying properties across Bath and North East Somerset means we know what to look for in this area. Damp and moisture problems are common in older Bath Stone buildings, which are porous and can absorb water, particularly where pointing or rendering has failed. Poor ventilation, often a result of modern refurbishments that have reduced natural airflow, can exacerbate these issues and lead to condensation and timber decay. Many historic homes also have outdated electrical systems, old heating systems, and potentially hazardous materials like lead pipes or asbestos-containing materials that require careful assessment. We check for these issues systematically and provide specific guidance on their implications.

Structural movement is another frequent finding in period properties, particularly Georgian and Victorian buildings that have settled over many decades. While some movement is normal in older buildings, our inspectors can identify concerning patterns that might indicate ongoing subsidence from clay shrink-swell, mining activity, or tree root influence. In areas like Combe Down where Bath Stone was extensively quarried, stability concerns have required past remediation work, and our surveys check for any signs of related issues. We examine walls for cracking patterns, check floor levels with a spirit level, and assess doors and windows for binding that might indicate structural movement.

Roof problems are particularly common in older properties, with traditional clay tiles, sometimes sourced historically from Bridgwater, and Welsh slate coverings showing age-related deterioration. Missing or slipped tiles, deteriorating ridge pointing, and damaged flashing can all lead to water ingress and internal damage. Our inspectors examine roofs from both inside and outside where accessible, providing a comprehensive assessment of condition. We also check loft spaces for signs of past leaks, inadequate insulation, and the condition of structural timbers including rafters, purlins, and joists.

Inappropriate repairs and alterations are a significant concern in traditionally constructed buildings that may not be protected by heritage legislation. We frequently identify problems caused by the use of modern materials on historic buildings, including cement-based renders that trap moisture, non-breathable paints, and the blocking of original ventilation paths. These issues can cause significant damage over time and may be expensive to rectify. Our survey will identify any such problems and advise on appropriate remediation measures using traditional, breathable materials.
