South Wales valleys homes deal with heavy rain, cool winters and long, damp seasons, so condensation builds up quickly on walls and windows. Because many Cardiff, Merthyr Tydfil and Rhondda Cynon Taf properties are older and tightly packed together, stale air often gets trapped indoors, which makes black mould and musty smells more likely. When…

South Wales homes live with rain almost all year, so moisture builds up fast in older walls and foundations. In fact, parts of the South Wales Valleys can see over 2,000mm of rainfall each year, while Cardiff itself experiences high humidity and frequent wet, windy days that keep building exteriors damp. Because so much of…

Living near the coast in Swansea, Port Talbot or low‑lying parts of Cardiff feels amazing, but the climate can be tough on your property. Because sea air carries moisture and salt, it pushes damp into walls, corners and hidden spaces much faster than in many inland areas. When you add frequent rainfall, older buildings and…

Many homeowners assume that a brand‑new property in South Wales will be “mould‑proof,” yet the reality is usually very different. During construction, builders use huge amounts of water in concrete, screed and plaster, so new homes often start life full of trapped moisture. Because modern properties are designed to be highly insulated and airtight, this…

Black mould is a dark, stubborn fungus that thrives in damp, warm spaces inside your home. It often appears on silicone sealant in bathrooms, especially around showers, baths, and windows where moisture lingers. Over time, these areas stay wet, so mould spores settle and spread across the silicone sealant. This growth does not just spoil…

Mould grows on fabrics when they stay damp for too long, which is common in South Wales homes. Moist air from everyday life condenses on cold walls, windows, and around wardrobes, so nearby clothes, curtains, and sofas absorb this moisture. Leaks from roofs, gutters, or plumbing can also wet fabrics, while poor ventilation stops them…

Why South Wales Homes Get Damp in Winter South Wales has cool, wet winters, so homes stay cold and humid for long periods. Because of this mix, moisture easily settles on chilly windows and external walls. Many houses in Cardiff, Newport, Swansea and the Valleys are older solid‑wall properties, so they struggle to dry out…

Mould in rented homes is now a serious legal issue, not just a cosmetic problem on walls and ceilings. Landlords across Wales and the wider UK face growing scrutiny because damp and black mould can make a property unfit for human habitation under modern housing standards. Recent cases and new rules, including the push behind…

South Wales sees frequent rain, high humidity and strong coastal winds, so older homes in Swansea, Cardiff and Newport trap moisture easily. As a result, condensation, rising damp and penetrating damp often turn into hidden leaks inside walls, floors and ceilings.​ PRBG Environmental works as a specialist partner for these properties, providing expert mould remediation,…

Bathrooms create perfect mould conditions because warm steam meets cold surfaces and then lingers on ceilings, tiles and grout. Poor or missing ventilation means this moisture cannot escape quickly, so walls and ceilings stay damp after every bath or shower. Over time, small specks of mould on ceilings, tile joints and silicone sealant can spread…

Mould is a living fungus that grows where walls stay damp, while mould stains are the dark marks left behind on paint and plaster. These stains often appear as black, green or brown patches on interior walls and ceilings in UK homes. They may start small; however, they quickly spread and can damage finishes, create…

Wall mould grows when excess moisture and everyday condensation sit on cold walls and ceilings for too long. It often appears as black, green or grey patches on painted surfaces, especially in corners and behind furniture. These patches may look small at first; however, they can spread quickly and damage plaster, paint and indoor air…

Black mould, or Stachybotrys chartarum, grows where humidity is high and ventilation is poor. These conditions are typical in older and rental properties across Cardiff, Merthyr Tydfil and Caerphilly.​ Mould spores can trigger coughing, wheezing, allergies and asthma flare ups in adults and children. Over time, it also stains plaster, peels paint and weakens wall…

South Wales homes face a perfect storm of conditions that allow mould to thrive before winter fully arrives. As temperatures drop and the heating goes on, moisture builds up indoors faster than many properties can safely release it. Older terraces, stone cottages and solid‑wall homes often have weaker insulation and ventilation. As a result, cold…
