White fascia and soffit with dark staining beside a cleaned section

uPVC cleaning across the North East

Green, grubby window frames, sills and seals cleaned by soft washing and pure water from the ground.

White uPVC that has gone green or grey

uPVC frames are sold as low maintenance, and they are, but they are not no maintenance. Over a few years the white plastic picks up a grey film of traffic dirt, green algae settles along the tops of frames and sills, and black marks gather in the corners and around the rubber seals.

PVC is one of the surfaces suited to soft washing, which uses a low pressure water system and a dilute solution to remove algae, mould and grime without harsh force. Our pure water window cleaning also cleans the frames, sills and rubber seals, not just the glass, with purified water brushed on and rinsed away.

Between the two, the plastic around your windows and doors can be brought back to a clean, even colour. Roofline boards such as fascias and soffits are covered on their own page.

Because the water fed poles reach upper floor windows from ground level, there is no ladder leaning on gutters, render or conservatory roofs while the frames are cleaned. Purified water has had the dissolved minerals removed, so it does not dry onto the plastic or the glass as spots and streaks. No detergents are used on the glass, and everything is left to dry naturally. Frames and sills can be cleaned on the same visit as the windows, the conservatory or the fascias at the same address.

How to clean uPVC window frames yourself

For light dirt on ground-floor frames, warm water with a little washing-up liquid and a soft cloth is enough. Work from the top of the frame down, clean the rubber seals with a soft brush, rinse with clean water and dry the sill so it does not streak. Avoid scouring pads, cream cleaners, bleach and solvents, which scratch or yellow the plastic and can make it attract dirt faster.

Where DIY stops working is green algae that keeps returning, black mould in corners and frames above the ground floor that you cannot reach safely. That is where uPVC cleaning with soft washing and purified water makes sense, as it treats the growth and reaches upstairs from the ground.

uPVC cleaning or uPVC restoration?

Cleaning removes what is sitting on the plastic: algae, traffic film, cobwebs and mould. uPVC restoration is a different job, aimed at frames that have gone chalky, faded or yellow because the surface itself has weathered. Cleaning will brighten most frames a great deal, but it cannot reverse sun damage. Our guide is uPVC restoration worth it explains the difference.

uPVC cleaning cost depends on how many windows and doors there are, how many storeys, how heavy the staining is and whether the glass, conservatory or fascias are being done on the same visit. We do not publish prices; the quote form is the quickest way to get one.

Why uPVC discolours

What builds up on plastic frames

The flat tops of frames and sills catch dust, pollen and spores, and rain keeps them damp. That is where the green line usually starts.

Seals and corners trap dirt that a quick wipe misses, which is why frames can look grubby even when the glass has just been cleaned.

Cleaning the frames regularly, along with the glass, stops the build up becoming stubborn and keeps the house looking cared for.
