RICS Level 3 Building Survey in Cwm, Blaenau Gwent

Cwm lies within the South Wales Coalfield, so a lot of the housing here was originally put up to serve the mining industry. That history brings its own set of risks, which our RICS Level 3 Survey is built to pick up. Beneath the area sits Carboniferous geology made up of coal measures, sandstones and shales, with clay soils that can shrink and swell as moisture levels change and trees draw water from the ground. Our surveyors look for the signs, from cracking in walls to doors that have stopped closing as they should.

Terraced homes and semi-detached houses make up most of the stock in Cwm, and plenty of them date from before modern building regulations. Solid masonry walls, original timber joinery and traditional slate roofs are common, and all of them can hide problems that are not obvious at first glance. With our Level 3 Survey, we look at every accessible part of the building, from the roof structure right down to the foundations, so you get a clear view of any remedial work that may be needed.

Homes near the Ebbw River and its tributaries can be exposed to flood risk, especially when heavy rainfall hits the Welsh valleys. As part of our survey, we look for a flood damage history and any signs that water has come into the property before, because that can affect long-term durability. We also flag places where surface water flooding could be an issue, given the valley topography of Cwm.

Construction in Cwm usually means solid wall masonry, often with 9-inch or 13.5-inch walls made from local stone or brick. Victorian and Edwardian terraces often use Pennant sandstone or red brick, and render finishes can hide a substrate that is already failing. Our surveyors know these building methods well, and they know the defects that tend to turn up in homes of this age and style.

• Mining subsidence assessment
• Damp and timber decay investigation
• Roof and chimney condition
• Foundation and ground movement analysis
• Flood risk evaluation
• Electrical and plumbing overview

That is why the RICS Level 3 Survey suits homes like the ones across Cwm, especially older terraced houses, character properties built before 1900, and any home where renovations or a change of use are planned. We look at the whole structure, including walls, floors, ceilings, roofs and the foundations. We also check the damp-proof course, insulation levels and how well the existing drainage is performing.

For Cwm homes, one of the biggest strengths of the Level 3 Survey is the attention we give to mining-related issues. Former coal mining areas can experience ground movement linked to historic extraction, and our surveyors know the warning signs, from crack patterns that point to subsidence to uneven floors and sticking doors or windows. If we spot anything that raises concern, we recommend a Coal Authority Mining Report so you can get firm information about the mining history beneath the property.

We also pick up on the defects that often show up in Welsh valley properties, including worn stonework, problems with original lead flashings, slipped slate tiles, and timber faults such as rot or woodworm in floor joists and roof trusses. Many homes in Cwm are old enough to have dated electrical wiring and plumbing that no longer meet current regulations, so we check for that too and give you a realistic sense of any upgrade work involved.

Thermal performance is part of the picture as well, and we note where insulation could be improved without trampling on period features. Our surveyors also record any asbestos-containing materials that may be present in properties built before the 1990s, so you have full information about possible hazards.

• Comprehensive structural assessment
• Detailed defect analysis
• Mine working risk evaluation
• Repair cost guidance
• Future maintenance recommendations
• Priority ratings for all issues

For buyers in Cwm, we particularly recommend a RICS Level 3 Survey where the property was built before 1900, because those older homes often carry a complicated history of alterations and repairs that need expert scrutiny. The solid wall construction seen in many Victorian and Edwardian terraces in the area behaves differently from modern cavity wall buildings, and our surveyors know how to judge these traditional methods properly.

If major renovations are on the cards, such as taking out internal walls, converting the loft or extending the property, the Level 3 Survey gives vital information about what is load-bearing and what structural work may be needed. Plenty of homes in Cwm have already been altered before, and our survey can show whether that work was done properly and whether it meets current building regulations.

Visible structural problems, such as large cracks in walls, serious damp or uneven floors, call for the detailed assessment that only a Level 3 Survey can provide. If the property is listed, or may sit within a conservation area, the survey will also flag the historical status of the building and any restrictions on future alterations.

The housing stock in Cwm is mainly made up of 3-bedroom terraced houses and 3-bedroom semi-detached properties, which reflects the area’s industrial past. Those property types often benefit most from a detailed inspection, because hidden defects can be easy to miss without an experienced surveyor.

• Pre-1900 terraced houses
• Properties with visible cracks or movement
• Homes planned for major renovation
• Listed buildings
• Properties near the Ebbw River
• Any home in a mining area

Homes in Cwm, Blaenau Gwent, often show defects tied to age and construction, and our RICS Level 3 Survey is designed to pick up those familiar issues. We then give you practical information about any remedial work that may be needed.

Damp is a regular problem in older terraced properties, especially those with solid walls and no proper damp-proof course. Rising damp can affect the ground floor walls, while penetrating damp often appears where slate roofs have slipped or lead flashings have worn out. Condensation can also become an issue where ventilation is poor, particularly in kitchens and bathrooms.

Given how much of the housing stock in Cwm is old, roofing defects crop up often. Slipped slate tiles, worn felt underlays and problems with original lead flashings around chimneys are regularly picked up during our surveys. Left alone, these defects can lead to water ingress and later damage to internal ceilings and walls.

Older homes can also suffer from timber defects, including rot and woodworm infestation in floor joists, roof trusses and window frames. Our surveyors tap timber elements to test for solidity and to spot any areas that may need a specialist to look further.

• Rising damp and penetrating damp
• Slipped slate tiles and roofing defects
• Timber rot and woodworm
• Subsidence and structural movement
• Outdated electrical wiring
• Drainage system issues
