Soffits, fascias, and cladding are some of the most visible parts of a property and some of the most neglected. They sit right at eye level from the street, yet they’re awkward enough to reach that most homeowners never get round to cleaning them, and most window cleaners don’t offer it as standard. Trendline cleans soffits, fascias, and cladding using the same ground-based Reach & Wash system that’s cleaned windows for over 2,000 households across the South East since we launched in Croydon in 2021.
Can You Pressure Wash Soffits and Fascias?
This is one of the most common questions we get, and the honest answer is: not the way most people mean it. A standard pressure washer on full power can force water behind uPVC panels, strip protective coatings, and in some cases crack older or brittle fascia boards, especially on properties where the material has already started to weather. It’s a common DIY mistake, and one that turns a straightforward cleaning job into a repair bill.
Our Reach & Wash system uses purified water at a controlled flow through a soft brush head, not a high-pressure jet. It’s specifically suited to uPVC, painted timber, and cladding materials that would be damaged by aggressive pressure washing, which is why we use the same gentler approach here as we do on windows and gutters, rather than switching to harsher equipment for this particular job.
Why Soffits and Fascias Turn Green and Grey Over Time
Algae and Mould Growth
Soffits and fascias sit in a shaded spot under the roofline, protected from direct sun and often from heavy rain too, which makes them an ideal environment for algae and mould to take hold. Green streaking is usually algae, while black or grey patches are more often mould, and both tend to spread fastest on north-facing elevations or properties close to trees where moisture lingers longer.
Weathering and UV Fading
Even without visible growth, white uPVC soffits and fascias gradually dull and yellow from years of UV exposure and general weathering. This isn’t something a regular clean can reverse entirely if the discolouration has gone deep into the material, but a proper clean removes the surface grime that makes the fading look far worse than it actually is, and it’s the difference between a roofline that looks tired and one that looks properly maintained.
How Do We Actually Clean Them Without Damage?
Ground-Based Reach & Wash System
The same telescopic poles and soft brush heads we use for windows and gutters handle soffits, fascias, and cladding. Purified water is pumped up the pole and applied with a controlled brush action that lifts dirt, algae, and grime without the force that risks pushing water behind panels or stripping protective finishes. Because it’s all done from the ground, there’s no ladder against the fascia board itself, which is exactly the point of contact that causes cracks and dents when cleaners work from height the traditional way.
What We Check While We’re There
While we’re cleaning, we’re also looking. Soffits and fascias are often the first place small problems show up, a hairline crack in a uPVC panel, a section that’s come loose from its fixing, or a fascia board that’s started to warp. We’ll point out anything we notice, not to upsell additional work, but because catching it early is usually the difference between a five-minute fix and a full replacement a year later.
Cladding and UPVC Cleaning
Cladding Cleaning
Cladding, whether it’s uPVC, timber-effect composite, or painted render board, collects the same grime as soffits and fascias but often over a much larger surface area. Ground-based reach and wash cleaning works well here too, particularly on properties where cladding runs up multiple storeys and would otherwise need scaffolding to reach safely. We clean cladding as a standalone service or as part of a wider exterior clean alongside windows and gutters.
UPVC Cleaning
Beyond soffits, fascias, and cladding, we also clean uPVC window frames, door frames, and other plastic exterior surfaces that pick up the same general grime and discolouration over time. This is often bundled into a window cleaning visit rather than treated as a separate appointment, since the same purified water and brush method used on the glass works just as well on the frame surrounding it.
Pairing It With Gutter Cleaning
Soffits and fascias sit directly beneath the guttering, so if your gutters are overflowing or leaking, the water runs straight down the fascia board and streaks whatever’s below it. That makes gutter cleaning and soffit and fascia cleaning a natural pair, since fixing one without addressing the other means the problem often comes straight back after the next heavy rain. Because we’re already on site with the Reach & Wash vehicle for one, adding the other to the same visit is usually the most efficient way to get the whole roofline looking consistent, and it tends to work out more cost-effective than booking them as two separate appointments months apart.
Frequently Asked Questions
How often should soffits and fascias be cleaned?
Once a year is usually enough for most properties, though homes under heavy tree cover or in shaded, damp spots may benefit from cleaning every six months to keep algae from building up.
Will pressure washing damage my soffits and fascias?
Standard high-pressure washing can force water behind panels and damage older or brittle materials. Our system uses controlled-flow purified water instead, which cleans effectively without that risk.
Can you clean cladding as well as soffits and fascias?
Yes. Cladding, whether uPVC, composite, or painted board, is cleaned using the same ground-based system, either as its own service or alongside soffit and fascia cleaning.
Do you clean uPVC window and door frames too?
Yes, this is often included as part of a window cleaning visit, since the same method used on the glass works equally well on the surrounding frame.
How much does soffit and fascia cleaning cost?
Pricing depends on the size of the property and how much roofline needs covering. We'll give you a free, no-obligation quote rather than a flat rate, since a small bungalow and a large detached house aren't the same job.
Can you tell if there's damage while you're cleaning?
Yes. We check for cracked panels, loose fixings, and early signs of warping while we clean, and we'll flag anything we notice rather than let it go unmentioned.
Can I book this with my regular window cleaning round?
Yes. Soffit, fascia, and cladding cleaning can be added to an existing window or gutter round, or booked as a one-off visit, whichever suits you better.
