RICS Level 2 Survey in Llanharry

Llanharry has experienced substantial growth over recent years, with property prices rising by 23% compared to the previous year and now sitting 12% above the 2022 peak of £242,652. This rapid appreciation makes it more important than ever to understand exactly what you are buying. The village has transformed from its historical roots in iron mining dating back to Roman times through to Elizabethan periods, and later coal mining in the 20th century, into a thriving residential community. Many properties in the area, particularly those built before 1980, may have underlying issues related to their age, construction methods, or the local geology that only a professional survey can uncover.

The local geology presents specific considerations for property buyers. Llanharry sits in an area with clay-rich soils that are prone to shrink-swell subsidence, a significant geohazard that can cause structural movement in properties. This risk is influenced by moisture changes, vegetation proximity, and the specific mineralogy of the soil. Combined with the area's mining heritage, where shallow mining remains could affect ground stability, a Level 2 Survey provides essential insight into these potential problems before you commit to your purchase.

Additionally, Rhondda Cynon Taf has a higher flood risk than the Welsh average, with approximately one in five properties at risk from rivers, surface water, and groundwater flooding. The nearby River Ewenni at Llanharan is noted for potential flood risk, and surface water flooding can occur in low-lying areas after heavy rainfall. A comprehensive survey will note any signs of previous water ingress or flood damage, helping you understand the full picture of the property you are considering.

The 2021 Census recorded Llanharry as a community of 3,748 residents across 1,537 households, reflecting the village's steady growth as a commuter settlement for Cardiff and the wider South Wales region. This growth has brought new developments like Bryn Meurig by Llanmoor Homes, which launched in April 2016 and offers 77 two, three, and four-bedroom homes on the edge of the village. Meanwhile, the broader Llanharan area has seen significant expansion, including the Michaels Grove development by Charles Church and Persimmon Homes on Enterprise Way, with properties ranging from £454,995 to £560,000.

• Clay soil subsidence risk
• Historical mining activity
• Higher than average flood risk
• Ageing housing stock
• Outdated electrical systems
• Roofing and drainage issues

Our experience surveying properties throughout Llanharry and the surrounding Rhondda Cynon Taf area means we know the types of issues that frequently arise. Older properties, which make up a significant portion of the local housing stock, commonly suffer from damp problems including rising damp due to failed damp-proof courses, penetrating damp from water ingress through walls or roofs, and condensation issues caused by inadequate ventilation. These problems can lead to timber decay, including dry rot and wet rot, which thrive in damp conditions and can cause significant damage if left untreated.

Structural issues are also relatively common, particularly in properties built before modern building regulations. This can include subsidence or settlement cracking, lintel failures, bulging walls, and roof movement. Given the clay-rich soils in the area and the historical mining activity, our surveyors pay particular attention to signs of structural movement, cracks in walls, and any unevenness in floors or ceilings. Electrical systems in older properties frequently do not meet current regulations and may require significant upgrading, representing a substantial cost to the buyer.

Roof defects are another frequent finding, particularly in older properties where original roof tiles may have deteriorated, mortar may have degraded, or chimney stacks may be showing signs of wear. Poor drainage, including blocked gutters and downpipes, can lead to water pooling around foundations, exacerbating any subsidence issues. For properties built before the 1970s, there is also a possibility of asbestos-containing materials, which our surveyors will note if identified.

Given the mix of property ages in Llanharry, from Victorian-era terrace houses in the village centre to new builds at Elms Farm and Bryn Meurig, we approach each survey with an understanding of the specific construction methods and materials used in that era. Properties from the interwar and postwar periods (1919-1970) often have their own particular issues, including the use of materials that were standard at the time but are now understood to have limited durability. Our surveyors know what to look for in each type of property, ensuring nothing is missed.
