RICS Level 3 Building Survey in Chepstow (NP16)

Our RICS Level 3 Building Survey provides a thorough examination of the property's visible and accessible elements. Unlike a basic mortgage valuation, this survey investigates the actual condition of the building fabric, identifying defects that could affect the property's value or require expensive repairs. Our inspectors physically access the roof space where safe and practicable, examine external walls, inspect windows and doors, and assess the condition of damp-proof courses and insulation. We examine floor surfaces, staircases, fitted kitchens and bathrooms, and test the operation of windows and doors throughout the property.

For properties in the NP16 area, our survey specifically addresses common issues found in local housing stock. We check for damp penetration in solid stone walls, which is particularly prevalent in older Chepstow properties built with local Old Red Sandstone or Carboniferous Limestone. These traditional stone walls, common in properties predating 1900 throughout Chepstow's town centre and the older village cores of Portskewett and Sedbury, often lack effective damp-proof courses and can suffer from rising damp, especially where ground levels have been raised over time. Our inspectors assess the condition of lime-based mortars, which were traditionally used in these older properties, and note where modern cement-based repointing may be trapping moisture.

We assess timber elements for woodworm and rot, which can affect period properties with traditional timber frames throughout the NP16 area. Many Victorian and Edwardian properties in Chepstow feature original timber sash windows, decorative timber work, and traditional timber floor structures that require careful inspection. Our surveyors examine roofing materials, including natural slate and clay tiles common on older properties throughout Monmouthshire, and check the condition of lead flashings and guttering systems that are prone to deterioration in the local climate. We also inspect rendered finishes, which are prevalent on both modern properties and refurbished older homes throughout the area, looking for signs of moisture penetration and render failure.

The report includes a clear condition rating system that helps you understand the severity of each issue identified. We explain any structural concerns in plain English, providing repair recommendations and cost guidance where appropriate. For properties in flood-risk areas along the Severn Estuary or near the River Wye, we note any signs of previous water damage, assess flood resilience measures that may have been installed, and advise on potential future risks. Our reports also include observations on energy efficiency, noting where insulation is lacking or where improvements could be made to reduce heating costs in the increasingly important energy-conscious property market.

The NP16 postcode covers Chepstow and surrounding villages including Portskewett, Caldicot, and Sedbury, each with distinct property characteristics that affect survey requirements. Chepstow town centre contains numerous Victorian and Edwardian properties with solid stone walls and traditional slate roofs, while newer developments like those on Crick Road in Portskewett (built by Edenstone Homes) and the Rockfield development by Bellway feature modern cavity wall construction. Understanding these construction differences is essential for accurate defect assessment, as the hidden structural elements vary significantly between older solid-wall properties and modern cavity-wall construction.

The local geology presents specific considerations for property condition. Parts of the NP16 area contain clay deposits that create shrink-swell risk, particularly in the lower Usk valley and areas near the Severn Estuary. During periods of prolonged dry weather or heavy rainfall, clay soils can expand and contract, putting stress on foundations and potentially causing structural movement. Our inspectors are trained to identify signs of subsidence or movement that may relate to these ground conditions, including cracking patterns, doors and windows that stick, and uneven floor levels. We examine the superficial deposits and underlying bedrock, which often includes Old Red Sandstone and Carboniferous Limestone, to assess potential ground stability issues.

Properties in low-lying areas near the River Wye or Severn Estuary face potential flood risks, and we specifically assess for evidence of previous water damage, damp penetration, and flood resilience measures. The tidal nature of the Severn Estuary means that properties in areas like Stroat and near the M48 bridge crossing can be affected by tidal surges, while heavy rainfall can cause surface water flooding in parts of Caldicot and Portskewett. Our surveyors look for water marks, salt efflorescence that indicates previous flooding, and assess the condition of any existing flood barriers or pumps that may have been installed. We also note the general aspect and drainage of the plot, which affects how quickly water can accumulate during heavy downpours.

Chepstow's conservation area contains a high concentration of listed buildings, from the famous castle to numerous historic townhouses along St Mary's Street, the High Street, and the Georgian terraces of St John Street. Properties in conservation areas or those with listed building status require careful assessment as they may have restrictions on repairs and improvements. Our survey reports highlight any conservation or listed building considerations and note where specialist advice may be required. The predominance of rendered finishes on both modern and refurbished properties in the area also requires specific inspection for moisture penetration and render failure, particularly on north-facing elevations where drying is slower.

• Conservation area properties require specialist assessment
• Listed buildings need detailed evaluation
• Flood risk areas need thorough inspection
• Clay soils require movement assessment
• Render finishes need damp inspection
