What it is

That grey-green film is not really dirt

White UPVC does not really get dirty. It gets a film on it. Traffic dirt, pollen and algae build up in a thin layer. A wet cloth just smears it about. It does come off with the right thing, not a harder scrub.

Heated pure water, not bleach

Heated pure water lifts the film off the plastic. Harsh cleaners can take the shine off too. They can leave UPVC looking chalky. A year later it looks worse.

Frames, sills and trims

The frame, the sill it sits on, and the trim round the edge. Black dirt builds up in the corners and the drain slots. A quick wipe never gets there.

Doors, porches and cladding

Front doors and porches take the most weather. They are the first thing people see. Panels and cladding come up the same way.

Fascias and soffits

The boards under the roof edge, cleaned from the ground. They sit right under the gutter. So they catch all that spills over the front of it.

Worth knowing

Where UPVC goes off first

It is never even. Some parts of a house stay white for years. Others go grey in one winter. You can mostly guess which.

Under the gutter

Fascias and soffits catch every spill. Has a gutter been spilling over? Then the boards under it will be the worst part of the house.

The side facing the road

Traffic film is real. Frames on the road side of a house go grey. The back of the same house does not.

North-facing and shaded

Anything that stays damp grows algae. Think of a porch under a tree, or a wall that never gets sun. It goes green, not grey.

Sills and drainage slots

Water sits on a sill and runs out through small slots in the frame. Those slots fill with black grime. They are almost never cleaned.

What cleaning will and will not do

If the UPVC is just dirty, it will come up white. That is a really pleasing job.

Some UPVC has oxidised. That means twenty years of sun have made the surface chalky. Rub it with a dry finger and your finger comes away white. Cleaning will make it better. It will not bring back the shine, because the plastic itself has worn.

That needs a restoration job, not a clean. I would rather tell you that before than after.

“Used JCM Hotwash for the first time today to clean windows, sills and cladding… James really does take pride in what he does and spends time ensuring that the end result is top notch!”

“He cleaned all the gutters, pvc fascia board, window and doors. He worked so hard, it’s been years since the PVC was cleaned. There wasn’t any pressure to have a regular window clean or contract.”

Questions

Before you ask

How much does UPVC cleaning cost?
It depends how much there is and what state it is in — a porch and a front door is a very different job from a full house of frames, fascias and soffits. Send a photo on WhatsApp or I will come and look. The quote is free and there is no obligation.
Will bleach or a pressure washer do the same thing?
Both can do more harm than good. Bleach can leave white UPVC looking chalky and dull, and a pressure washer can force water past seals and drive grime further into the texture. Heated pure water and the right brush lifts the film without any of that.
Can you make old yellowed UPVC white again?
Honestly, no — not by cleaning. Yellowing and chalkiness are the surface of the plastic breaking down under years of UV, not dirt sitting on top of it. Cleaning will improve it noticeably. It will not make it look new. If that is what you are after, you want a UPVC restoration specialist.
Do you clean fascias and soffits as well?
Yes, from the ground. They are usually the worst part of the house because they sit right under the gutter, and they make the biggest visible difference for the least fuss.
Can it be done with a window clean?
Yes, and it is the sensible way round. The frames and sills get done as part of every window clean anyway — a full UPVC clean is the same idea extended to the doors, porch, cladding and boards.
How often does UPVC need doing?
Once a year keeps it easy. Leave it five years and it still comes up, it just takes considerably longer — which is why the first clean on a neglected house costs more than the ones after it.
