RICS Level 3 Building Survey in SA13

SA13 takes in Port Talbot and the surrounding valley communities of Cymmer, Glyncorrwg and Blaengwynfi, places with a strong industrial past. A lot of the homes here go back to the late Victorian and Edwardian periods, when they were built for workers in the collieries and steelworks. Those older buildings often use local stone and brick, and they can hide structural problems that only a comprehensive survey will uncover.

In SA13 properties we regularly come across a handful of familiar issues. Roofing defects are especially common, from slipped or missing tiles to worn felt underlay and failing lead flashing, all of which can threaten the building’s integrity. Timber decay and woodworm turn up too, particularly where age-related damp has taken hold. With historical coal mining across the area, we also look carefully for subsidence or ground movement that could affect foundations in former mining locations.

Rising damp is a frequent concern in SA13 period homes, especially where solid walls have no modern damp proof course. We assess how far moisture has travelled and advise on the most suitable remedy. Penetrating damp, often caused by damaged roof coverings or failing external render, is another regular sight. Our report sets out where the damp is coming from and what should be done about it. In parts of Port Talbot, salt-laden air from Swansea Bay can also speed up the weathering of external walls exposed to prevailing winds.

Beneath Port Talbot, the local geology brings its own set of issues for owners. SA13 sits on South Wales Coalfield strata, with coal seams that were worked heavily throughout the 19th and 20th centuries. That mining history means ground stability is still a concern in some spots, especially where shallow seams were taken out. Cymmer and Glyncorrwg, where mining activity was particularly intense, deserve extra care during a structural assessment.

• Rising and penetrating damp
• Timber decay and woodworm
• Structural movement and subsidence
• Render and pointing defects
• Outdated electrical systems

The RICS Level 3 Survey is the most detailed inspection we offer for residential property. Unlike a basic valuation or a Level 2 survey, this structural assessment examines every accessible part of the building in significant detail. We set out repair costs, priority ratings and plain-English explanations for every defect found.

We inspect the roof structure, including rafters, purlins and any visible timber defects. The covering materials are checked too, so any areas of concern can be flagged. Chimney stacks are looked at for structural soundness, with movement or deterioration noted. Walls are assessed for cracking, damp penetration and the condition of render or pointing. Floors, ceilings and joinery are all part of the survey, so anything major or in need of specialist attention is identified.

Drainage is also considered, tested where accessible, and any visible pipework is examined. Electrical and heating systems are checked visually, with referrals for qualified specialists where needed. We assess the overall structure, including load-bearing walls, beams and foundations. Every element is photographed and recorded in your report.

For SA13 homes in particular, we pay close attention to features that are common in the local stock. Many Victorian and Edwardian terraces still have original sash windows, decorative plasterwork and solid brick walls, all of which need a specific approach to assessment. We understand how these traditional details age, and what upkeep they tend to need. Our report tells you not just what is wrong, but why it happened and what it will cost to fix.

Knowing how SA13 properties were built helps explain why certain defects keep appearing and how they affect the building’s structural integrity. Most housing in the Port Talbot area dates from periods of rapid industrial growth, when speed and economy were put ahead of everything else in order to house a growing workforce.

Victorian and Edwardian terraced houses, which make up a large share of the SA13 housing stock, were generally built with solid brick walls. Without cavity insulation, they are more exposed to damp penetration if the pointing fails or rising damp appears. The original lime-based mortars in these properties are more permeable than modern cement mortars, which has advantages and drawbacks. They let the building breathe, but they also mean the pointing may need more regular maintenance.

In places like Sandfields and Aberavon, many semi-detached properties from the 1920s and 1930s were built with cavity walls, though those cavities were often left uninsulated at the time. At ground level, solid concrete floors can be vulnerable to damp if the original damp proof course has broken down. Flat roof sections, common on some 1930s extensions, often need close attention as felt or asphalt coverings reach the end of their lifespan.

Original fireplaces, decorative cornices and bay windows add real character, but they also call for specialist assessment. Our inspectors know how these features sit within the wider structural condition, so we can tell when they point to a deeper problem and when they are simply sound original details that need routine care.

SA13 includes a wide mix of property types, and each one needs a slightly different approach during the survey. By understanding that mix, we can focus on the issues most likely to affect the local housing stock.

Terraced houses dominate much of SA13, especially close to the town centre and in former mining villages. Because these homes often share structural walls with next door, problems in one can affect the other. Our survey checks shared walls closely and looks for movement that could point to structural concerns between properties. The narrow plots typical of Victorian terraces can also limit access to rear elevations, which can make a full inspection more difficult.

Semi-detached homes in SA13 usually date from the early to mid-20th century, built as the local coal mining and steel industries expanded. They often come with larger gardens than terraces and may still retain period details that need careful review. Many were built with solid walls and no cavity insulation, so damp can be an issue if maintenance has been neglected. A lot have also been extended over time, so we look at the original building and any additions together.

Detached homes in SA13 are generally newer, or found in more affluent parts of the area. They have independent structural integrity, but they still need a proper inspection, especially where there are signs of movement or subsidence. With more complex roof forms and larger footprints, any defect can have a wider impact. Some detached houses locally were built using non-standard methods, which can call for specialist assessment.

• Victorian and Edwardian terraced houses
• 1930s semi-detached properties
• Modern detached homes
• Period properties with original features
• Properties with extended layouts
• Converted apartments

The SA13 postcode covers places with different flood risk profiles, reflecting the varied geography of Port Talbot. Homes near the River Afan or in lower parts of the town centre may be exposed to fluvial flooding, while coastal locations can face tidal flooding during severe weather. Our survey includes a visual check of flood vulnerability, although we always advise looking at specialist flood risk data from Natural Resources Wales for fuller information.

Surface water flooding can also affect homes in the valley parts of SA13, particularly where drainage systems struggle during heavy rain. The steep gradients in the Afan Valley can speed up runoff, which may leave water pooling in lower-lying areas. During the inspection we note any evidence of earlier flooding, including water marks, damaged plaster or warped flooring that could point to past events.

We also look beyond flooding and consider other environmental factors that may affect SA13 properties. The coastal setting means salt spray can wear down external surfaces more quickly, especially on exposed homes. Properties close to the steelworks may have been subject to industrial emissions over many years, which can affect external render and metalwork. If we identify any environmental concerns, our report will flag them and recommend further specialist investigation where appropriate.
