Why UPVC Cleaning Is Essential for South Wales Properties
UPVC (unplasticised polyvinyl chloride) is the most popular material for fascias, soffits, bargeboards, window frames and door frames across South Wales. It's durable, low-maintenance and designed to last 20–30 years — but "low-maintenance" doesn't mean "no-maintenance." In the wet, mild climate of South Wales, UPVC surfaces quickly become colonised by green algae, black mould and grey atmospheric staining that makes even the best-maintained properties look tired and neglected.
Professional UPVC cleaning restores these surfaces to their original bright white (or coloured) finish, dramatically improving your property's kerb appeal. At PB Cleaning Solutions, we provide specialist UPVC cleaning across South Wales, serving homeowners in Newport, Cardiff, Cwmbran, Pontypool, Chepstow and beyond.
What Causes UPVC Discolouration?
UPVC discolouration has several causes. Green algae thrives on north and east-facing surfaces where moisture lingers. Black mould grows in sheltered areas with poor air circulation, particularly under eaves and behind downpipes. Grey atmospheric staining — caused by pollution, exhaust fumes and industrial fallout — gradually dulls the UPVC surface over time. In coastal areas, salt deposits accelerate this process.
Left uncleaned, these deposits don't just look unsightly — they can permanently stain the UPVC surface. The longer algae and mould remain, the deeper they penetrate the microscopic pores in the plastic, making them progressively harder to remove. Regular cleaning prevents permanent discolouration and keeps your UPVC looking fresh for decades.
Our UPVC Cleaning Process
We use specialist UPVC cleaning solutions that are formulated to break down algae, mould and atmospheric staining without damaging the UPVC surface. Unlike household cleaning products, our professional solutions contain active ingredients that kill biological growth at its root, rather than simply masking it. We apply the solution by hand using soft microfibre cloths and brushes — never pressure washers — to ensure a thorough, scratch-free clean.
Pressure washing UPVC is one of the most common mistakes we see. High-pressure water forces moisture behind fascia boards, damages seals on window units and can even distort thin UPVC panels. Our hand-applied method is slower but delivers vastly superior results with zero risk of damage.
UPVC Surfaces We Clean
- Fascia boards — the front-facing boards running along the roofline
- Soffits — the underside panels beneath the fascia
- Bargeboards — the boards running along gable ends
- Window frames — all UPVC window frame exteriors
- Door frames — front, back and side door frames
- Conservatory frames — see our conservatory cleaning service for full details
- UPVC cladding — external wall cladding panels
- Guttering exteriors — for internal gutter clearing, see our gutter cleaning service
UPVC Cleaning vs UPVC Replacement
Many homeowners assume that heavily discoloured UPVC needs replacing — an expense that can easily run into thousands of pounds for a full set of fascias, soffits and bargeboards. In the vast majority of cases, professional cleaning can restore UPVC to near-original condition for a fraction of the replacement cost. Even UPVC that looks beyond saving often responds remarkably well to professional treatment.
Areas We Cover for UPVC Cleaning
We provide UPVC cleaning throughout South Wales, including Newport, Cardiff, Cwmbran, Pontypool, Caerphilly, Chepstow, Caldicot, Magor and Bristol.
Combine UPVC Cleaning with Other Services
UPVC cleaning pairs naturally with window cleaning and gutter cleaning — tackling all three on a single visit gives your property a complete roofline refresh. Many customers also add softwashing for rendered walls and driveway cleaning for a full exterior transformation.
How Much Does UPVC Cleaning Cost?
UPVC cleaning prices depend on the property size, the number of surfaces and the level of staining. A typical 3-bedroom semi-detached house costs between £100 and £220 for a full UPVC clean including fascias, soffits, bargeboards and window frames.
