RICS Level 3 Building Survey in Llanegwad

The Llanegwad area presents unique challenges for property buyers that make a detailed structural survey essential. Many homes in this rural Carmarthenshire parish are Victorian or Edwardian period properties constructed using traditional methods that differ significantly from modern building standards. The predominance of solid-walled construction using local rubble stone and sandstone, combined with lime mortar pointing, requires specialist knowledge to assess properly. These breathable traditional structures behave very differently from modern cavity-walled homes, and using inappropriate modern materials during repairs can cause serious damage.

Our surveyors understand the specific construction methods used in Carmarthenshire properties and can identify defects that are common to older buildings in the area. These include damp penetration through porous stone walls, movement in walls caused by thermal and moisture cycles, and issues arising from the use of inappropriate modern materials on traditional breathable structures. We frequently encounter properties where cement renders have been applied to solid stone walls, trapping moisture and causing internal damp problems that would not occur with traditional lime-based renders. A Level 3 survey provides the detailed analysis needed to understand these issues and their implications for the property's long-term condition.

Additionally, the local geology presents specific considerations for property owners in Llanegwad. The bedrock beneath the area consists of Palaeozoic sedimentary rocks, including mudstones, siltstones, and sandstones, while the valley floors contain alluvial deposits from the River Tywi and River Cothi. Areas with clay-rich soils can experience shrink-swell movement, where the ground expands during wet periods and contracts during dry spells, potentially affecting foundations. This is particularly relevant given that Carmarthenshire has areas with notable clay shrink-swell hazard, and our inspectors are trained to look for signs of such movement, especially in properties built on the valley floors where alluvial deposits are present.

The flood risk in Llanegwad also warrants specific attention during the survey process. With 58 properties at high risk and 84 at medium risk from surface water and ordinary watercourse flooding, and a history of flooding from small watercourses at Nantgaredig, our surveyors pay particular attention to drainage, ground levels, and flood resilience measures when inspecting properties in vulnerable locations.

Our experience surveying properties throughout the Llanegwad parish reveals several recurring issues that buyers should be aware of. Damp is the most frequently encountered problem in older buildings, particularly those with solid-walled construction. This can manifest as rising damp due to high ground levels or poor drainage, penetrating damp from damaged gutters or cracked renders, and condensation issues resulting from inadequate ventilation combined with modern airtight improvements. In properties where cement-based renders have been applied to traditional stone walls, we often find severe penetrating damp as the moisture cannot escape through the impermeable surface.

Movement in walls is another common finding, with cracks appearing due to various causes including thermal movement, lintel failure over windows and doors, and in more serious cases, subsidence related to ground conditions. Properties in areas with clay soils are particularly susceptible to foundation movement, and our surveyors pay close attention to the junction between walls and foundations when inspecting such properties. The shrink-swell phenomenon affecting clay-rich soils in parts of Carmarthenshire can cause significant foundation movement, particularly during periods of drought followed by wet weather.

Roof problems are frequently identified, particularly in older properties where original slate roofs may have been repaired with inappropriate materials or where gutters and downpipes have deteriorated. The traditional use of Welsh slate in the region means that many roofs are now reaching an age where ongoing maintenance becomes increasingly important. We commonly find issues with valley gutters filling with debris, slipped slates at ridges, and deterioration of lead flashings around chimneys. Our inspectors examine roof spaces accessibly, checking for signs of past water ingress, inadequate ventilation, and deterioration of structural timber.

Properties in the Llanegwad area also face specific environmental risks that our surveyors assess. The proximity to the River Tywi and River Cothi means that fluvial flooding is a consideration for properties in the valley floor, while the history of watercourse flooding at Nantgaredig demonstrates that even smaller watercourses can pose significant flood risks. Surface water flooding during heavy rainfall events is also a concern, particularly where drainage systems are overwhelmed.

• Rising and penetrating damp
• Wall movement and cracking
• Roof covering deterioration
• Foundation movement and subsidence
• Timber decay in roof structures
• Poor drainage around foundations
• Flood damage and water ingress
• Inappropriate modern materials on traditional structures

While Llanegwad is primarily known for its period properties, there is some new build activity in the area for buyers seeking modern construction. Planning permission was granted in January 2024 for a new dwelling adjacent to Ty Howell in Llanegwad (SA32 7NJ), representing a single new build opportunity in the village. Previously, a 35-dwelling development was proposed for Nantgaredig within the Llanegwad parish, though this was turned down in September 2024 due to planning agreement issues.

For buyers considering new build properties in the area, a Level 3 survey can still provide valuable reassurance despite the younger construction age. While major structural defects are less likely in recently built properties, our survey can identify any snagging issues, verify the quality of construction, and ensure that the property meets current building regulations. For properties in the SA32 7 area, new build prices in the region of £425,000 represent a guide for modern construction costs in this desirable rural location.

It is worth noting that even newer properties can have defects, particularly where developers have used budget materials or where construction has been rushed. Our thorough inspection examines all accessible elements regardless of the property age, ensuring you have complete confidence in your new home purchase.

The Llanegwad parish contains several notable listed buildings that require particular attention during the survey process. These include the Church of St Egwad, dating from the 10th-11th century and restored in the 19th century, the Church of the Holy Trinity built in 1865 of local sandstone, the Grade II listed Red Lion public house (mid-19th century rubble stone construction with slate roof), and Ty Llandre, a late 17th-century house. If you are considering purchasing a listed property or any building within the parish, our surveyors understand the additional considerations that apply.

Listed building consent is required for most works affecting the special historic interest of such properties, and our reports highlight any identified defects that might require such consent. We also note the use of inappropriate modern materials that can cause damage to traditional buildings, such as cement renders trapping moisture within solid walls, or non-breathable paints preventing the evaporation of moisture from stonework. The Red Lion, for example, has roughcast render on its gable end that may require careful assessment, while Ty Llandre's steep corrugated iron roof represents a traditional but now obsolete roofing material that may require ongoing maintenance.

For properties in the wider Carmarthenshire area, the presence of 1,848 listed buildings demonstrates the region's rich architectural heritage. Our surveyors are experienced in assessing traditional construction methods and can provide advice on the repair and maintenance approaches appropriate for historic buildings, ensuring that any work carried out preserves the building's character while addressing structural concerns. Carmarthenshire has 28 designated Conservation Areas, and while Llanegwad itself is not specifically designated, many nearby towns including Llandeilo and Llandovery have Conservation Area status, reflecting the county's commitment to preserving its architectural character.

Understanding the construction methods used in Llanegwad properties is essential for accurate survey assessment. The predominant building material in the area is local rubble stone, varying from rough-cut field stones to more regular sandstone blocks depending on the property age and status. Holy Trinity Church, built in 1865, exemplifies the use of local sandstone as a more prestigious building material, while everyday dwellings typically used more rustic rubble stone construction.

Traditional buildings in Llanegwad feature solid-walled construction rather than modern cavity walls. These thick walls, typically 450-600mm thick, are constructed from stone held together with lime mortar rather than cement. This construction method is breathable, allowing moisture to evaporate rather than becoming trapped, which is essential for the long-term health of the building. Our surveyors understand these construction methods and can identify when modern alterations have compromised the breathability of traditional structures.

Roofing in the area traditionally used Welsh slate, which became widely available in Carmarthenshire by the end of the 19th century thanks to the railways. Prior to this, thatch and stone tiles were common, and some older properties may still retain these original coverings. Corrugated iron was also used for roofing in the late 19th and early 20th centuries, and we still encounter this material on properties like Ty Llandre. Understanding these traditional materials helps us assess their current condition and advise on appropriate maintenance approaches.
