uPVC product chemistry
We use pH-balanced, surfactant-rich cleaners formulated specifically for plasticised PVC — they release surface contamination without attacking the UV-stabiliser layer that keeps boards white.

Service Overview
Understanding fascia & soffit cleaning
What it is
Restoration cleaning of uPVC fascia boards, soffit panels, bargeboards and decorative cladding using uPVC-specific cleaners, microfibre detailing and pure-water rinsing — leaving a streak-free, bright-white finish.
Who it's for
Anyone whose white boards have gone grey, green or black, where the previous owner's high-pressure clean has left marks, or where a quote for full replacement has shocked them. 90% of 'replacement' jobs are really cleaning jobs.
When you need it
Year-round in dry weather. Best paired with a gutter clear so any rinse run-off is captured immediately. Typically done before house sale, before painting decisions, or as part of overall exterior refresh.
Why professional help matters
Pressure-washing uPVC at the wrong angle drives water behind boards and into the loft. Bleach-only treatments leave white tide-marks. Generic exterior cleaners leave a film that re-attracts dirt within months. Specialist product + hand-detailing is what delivers a result that holds.
If left untreated
The cost of doing nothing.
- Black algae on white uPVC permanently embeds within 3 years if untreated.
- Stained fascia and soffits drop kerb appeal — and can knock real money off a sale price at viewing.
- Algae mats hold moisture against the board, accelerating bracket corrosion behind.
- Painting over dirty uPVC fails within a season — every job becomes two.
Common mistakes
What we see go wrong.
- Replacing instead of cleaning — five times the cost for the same end visual.
- Pressure-washing soffit vents and driving water into the eaves.
- Using bleach without a rinse — leaves white halos around every spray.
- Hiring a window cleaner with a Karcher and hoping for the best.
Our Process
A predictable system, from first call to clean-up
- 01
Inspection
We identify board type, stain type, vent layout and any cracked or warped sections before quoting.
- 02
Pre-Treatment
uPVC-specific cleaner applied with low-pressure spray, 5-minute dwell to lift surface contamination.
- 03
Hand Detailing
Microfibre-headed brushes worked along every length — including the underside of soffits — by hand.
- 04
Pure-Water Rinse
Reach & wash rinse leaves no spotting, no streaks, no residue to re-attract dirt.
- 05
Final Walk-Round
We inspect with you, flag any board damage spotted, and only invoice when you're satisfied.
The Benefits
What you actually get for the money.
Cheaper than replacement
Typically 80% less than installing new boards.
Visually identical to new
Bright, even white finish — neighbours assume you replaced them.
Streak-free finish
Pure-water rinse means no dry-spot marks on darker boards or coloured uPVC.
Vent-safe
Low pressure protects soffit vents and felt.
Minimal disruption
Timing varies by job — confirmed at quote.
Bundles brilliantly with gutter clear

Deep Detail
The technical bit — for the people who like to know
Painted vs woodgrain vs coloured uPVC
Coloured and woodgrain uPVC (Rosewood, Anthracite Grey, Cream) needs gentler products and softer brushes to avoid dulling. We carry the right combination on every job.
Why pressure washing fails
Above 800psi, uPVC surface texture roughens and traps dirt faster than ever. Within a year it looks worse than before the clean. Our hand-detail method delivers genuinely sustainable results.
Cladding, bargeboards and porches
Same process, same product — quoted by linear metre. Decorative finials and dentil mouldings hand-cleaned with detail brushes.
Residential vs commercial
Domestic fascia cleans are our bread and butter; we also handle small commercial uPVC (shopfronts, signage frames, school cladding) on quotation.
