RICS Level 3 Building Survey Llanwrthwl

The character of Llanwrthwl's housing stock sets it apart from more urban areas. Many properties here are constructed from local stone using traditional methods that have been practiced for centuries. Buildings such as Talwrnmaenog Farmhouse, a Grade II listed C17 house with rubble-stone walls, and Llannerch-y-Cawr, a Grade II* listed C15 stone-built cruck-framed hall house, represent the type of historic properties you might encounter in this area. These buildings require an experienced eye to assess properly, as their construction methods differ significantly from modern cavity-wall buildings.

Our RICS Level 3 surveys include detailed examination of walls, roofs, floors, foundations, and structural elements. We check for signs of damp which is particularly relevant given the local climate and the age of many properties. The mountainous nature of the surrounding parish means properties can experience damp conditions, especially in properties with solid walls rather than modern cavity wall construction. We assess timber conditions, including joists and beams that may show signs of rot or insect activity, which is particularly important in older buildings where original timber framing may still be present.

Our inspectors examine roof coverings, paying special attention to slate and stone tile roofs common to the area, looking for slipped or damaged tiles and deterioration of mortar joints. The traditional slate roofs found on many Llanwrthwl properties require careful inspection, as age and weather exposure can lead to deterioration that might not be immediately visible from ground level. We also inspect chimneys, which are a common feature on period properties and can suffer from decay in mortar joints and flashing.

The location of Llanwrthwl on the River Wye and River Elan means flood risk is a consideration for some properties, particularly those in lower-lying positions near the river valleys. A Level 3 survey includes assessment of flood resilience measures and evidence of previous water ingress. Given the mountainous nature of the surrounding parish, surface water drainage and the condition of retaining structures also receive attention during our inspection. Properties in areas such as The Old Mill and Tycoch, which have sold recently, may have specific flood considerations due to their locations.

Properties in Llanwrthwl showcase traditional Welsh building techniques that have evolved over centuries. The predominant construction materials include local rubble-stone, often limewashed, with boulder footings supporting the walls. Roofs typically feature slate or stone tiles, reflecting the availability of these materials in the surrounding hills. Understanding these construction methods is essential for identifying appropriate repair techniques and materials. Our surveyors recognise that improper repairs using modern cement-based mortars can actually cause damage to historic stonework by trapping moisture.

Many older properties in the area will have solid wall construction rather than modern cavity walls. This affects insulation properties and may influence your decisions regarding energy efficiency improvements. Solid wall properties can be more difficult to insulate without causing damp issues, and any improvements must be carefully considered to avoid damaging historic fabric. Our surveyors are familiar with the challenges of improving thermal performance in historic buildings while preserving their character and complying with listed building requirements.

The rural nature of Llanwrthwl means some properties may have septic tanks or private water supplies rather than mains connections. A Level 3 survey will identify these features and note their condition, though we always recommend specialist testing for water quality and drainage surveys. Properties in more remote parts of the parish may rely on private boreholes or spring supplies, and our report will highlight any matters requiring further investigation by specialists.

• Private drainage systems

Based on our experience surveying properties throughout the Wye Valley, we regularly encounter several common issues that affect homes in the Llanwrthwl area. Understanding these problems helps you know what to expect from your survey and what priority should be given to any remedial work. Many of these issues relate directly to the age and construction methods of traditional Welsh buildings.

Damp penetration is one of the most frequently identified issues, particularly in properties with solid stone walls. The local climate, with its high rainfall and relatively mild temperatures, creates conditions where moisture can penetrate porous stonework and lime mortar. Rising damp can also be a problem where original damp proof courses have failed or were never installed. Our surveyors use thermal imaging and moisture meters to assess the extent of any damp issues and recommend appropriate remediation.

Timber decay affects many period properties, particularly where roof timbers or floor joists have been exposed to prolonged damp conditions. We inspect all accessible timber for signs of rot, woodworm activity, and fungal growth. In older properties with original cruck frames or oak beams, we pay particular attention to joint connections and any signs of structural movement that might indicate problems with the main structural elements.

Roof deterioration is common given the age of many properties in Llanwrthwl. Slate and stone tile roofs, while durable, eventually require maintenance and replacement. We check for slipped or missing tiles, deteriorated mortar on ridge tiles, and condition of lead flashing around chimneys and dormer windows. Poor roof maintenance can lead to water ingress and subsequent damage to internal timbers and finishes.

• Timber rot and woodworm
• Roof slate deterioration
• Chimney stack condition
• Pointing and mortar decay
• Structural movement in stone walls
