RICS Level 3 Building Survey in Tongwynlais

Tongwynlais presents a diverse mix of property types that each require careful inspection during the survey process. The village has a significant number of older properties, many of which date back to the Victorian and Edwardian periods, alongside more modern developments that have been constructed over the past few decades. This variety means that a comprehensive RICS Level 3 Survey is particularly valuable, as our inspectors can identify issues that are specific to different construction eras and materials. The presence of historic buildings, including listed properties near Castell Coch and throughout the village conservation area, means that certain properties may have hidden defects related to their age, construction methods, or previous modifications that only an experienced surveyor would recognise.

The local geology in the Tongwynlais area presents specific considerations that our surveyors take into account during every inspection. Being situated north of Cardiff, the region features Carboniferous Limestone and Coal Measures geology, which can influence the type of ground conditions found beneath and around local properties. Properties in this area may be built on clay soils, particularly where mudstone or shale is present, which can lead to shrink-swell movement that affects foundations over time. Additionally, Tongwynlais is located in South Wales, an area with historical coal mining activity, meaning that some properties may be at risk of mining-related subsidence. Our surveyors are trained to identify the signs of these potential issues and will provide you with specific recommendations if concerns are identified.

The proximity of Tongwynlais to the River Taff also means that certain properties, particularly those in lower-lying areas near the river, may have some exposure to flood risk. While this varies significantly depending on the exact location of the property, our inspectors will assess the general flood risk indicators during their survey and include relevant information in your final report. Understanding these local factors is crucial when purchasing property in Tongwynlais, and our surveyors combine their knowledge of local conditions with a thorough physical inspection of the property itself to provide you with the most complete picture possible.

• Thorough inspection of all accessible structural elements
• Identification of damp, rot, and timber defects
• Assessment of roof condition and insulation
• Evaluation of foundation and ground floor conditions
• Review of any alterations or extensions
• Clear traffic light rating system for prioritising issues

Properties in Tongwynlais, particularly those of traditional construction, can present a range of issues that our surveyors frequently encounter during inspections. Many of the older properties in the village are constructed from local stone or traditional brick, which can be prone to specific defects over time. Rising damp is a common issue in solid-walled properties that were built before modern damp-proof courses became standard, and our inspectors will carefully assess the condition of walls, floors, and timber elements for signs of moisture penetration. Penetrating damp, often caused by damaged roof coverings, defective flashing, or degraded pointing, can also be prevalent in older properties and may lead to more serious structural problems if left untreated. We have inspected numerous properties in the village where poor previous repairs using inappropriate modern materials have caused additional problems.

Timber defects are another significant consideration for properties in Tongwynlais. Many traditional houses feature timber-framed construction, wooden floor joists, and original joinery that can be affected by woodrot or woodworm infestation over time. Our surveyors will probe accessible timber elements to assess their condition and identify any areas of concern that may require specialist treatment or structural reinforcement. The presence of stone spiral staircases in some properties, as noted in local property listings, indicates the traditional features that characterise much of Tongwynlais housing stock, and these historic elements require careful assessment during any survey. We have found that older properties with original timber features often require more detailed investigation to ensure structural integrity.

Roof defects are consistently among the most common issues identified in properties throughout the Cardiff and Tongwynlais area. Slipped or broken tiles, deteriorated pointing to ridge tiles, and damaged or missing flashing around chimneys can all allow water ingress that leads to internal damage. Our inspectors will access the roof where it is safe and practical to do so, or use drone technology where appropriate, to thoroughly assess the condition of the roofing structure and identify any repairs that may be needed. Given the age of many properties in Tongwynlais, roofs may also lack adequate insulation or ventilation, which our report will flag as areas for improvement. In our experience, properties along the older sections of the village near Castell Coch often have complex roof structures that require careful inspection.

• Rising and penetrating damp
• Timber rot and woodworm
• Roof defects and tile damage
• Chimney and flashing issues
• Foundation movement and subsidence
• Inappropriate modern alterations

The predominant construction methods used in Tongwynlais reflect both the history of the area and the practical availability of local materials throughout the years. Many of the older properties in the village are constructed from local stone or brick, which were the primary building materials available when these homes were originally built. These traditional solid-wall constructions behave differently from modern cavity-walled properties, and they require specific assessment criteria that our surveyors are trained to apply. Understanding whether a property has solid walls, cavity walls, or a combination of both is essential for accurately assessing its thermal efficiency and identifying potential issues with moisture management.

Properties built before approximately 1919 typically have solid wall construction, meaning they do not have the cavity between internal and external walls that modern buildings feature. These solid walls can be more prone to damp penetration and may have less effective insulation than newer properties. However, they also often feature more robust construction using thicker walls and quality materials that have proven durable over many decades. Our surveyors will assess the specific construction type of your prospective property and explain how this affects both its current condition and any future maintenance requirements you should anticipate. In Tongwynlais, we find that many Victorian and Edwardian properties retain their original features but may have had insensitive modifications over the years.

The presence of the historic Castell Coch and various Grade II listed properties in Tongwynlais indicates that the village has a significant number of historic buildings that may require specialist consideration during the survey process. Listed buildings often have restrictions on what alterations can be made, and our surveyors will note any visible signs of previous works that may not have received proper consent. If you are purchasing a listed property, we recommend that you obtain specialist advice from a conservation architect in addition to the standard survey, as certain defects may require traditional repair methods that are more specialist and potentially costly than standard modern alternatives. Properties in the conservation area near the castle particularly benefit from our detailed assessment, as we understand the specific requirements for maintaining historic buildings.
