uPVC Cleaning

Window frames, doors, porches and sills cleaned with uPVC-safe soft washing across Prescot, Knowsley and St Helens.

What we clean

White uPVC shows every bit of grime, and around Merseyside it picks up plenty. Blastaway Pressure Washing Services cleans all the uPVC around your home:

  • Window frames, sills and glazing beads
  • Front doors, back doors and patio doors
  • Porches and door canopies
  • Garage door frames and side trims
  • The glass itself, cleaned along with the frames

We cover Prescot, Whiston, Rainhill, Huyton, St Helens, south Liverpool and across to Widnes.

How we do it

The first job is working out what you’re actually looking at, because green algae, black mould in the seals, traffic film and oxidised plastic all need slightly different handling. Once we know, the frames get a low-pressure soft wash with a solution made for uPVC, which breaks down the growth and grime without pushing water past the seals.

Corners, seals, beads and sills get gone over by hand, since that’s where the muck hides and a rinse alone won’t shift it. The glass is cleaned at the same time, then the whole lot gets a final rinse so nothing is left sitting on the plastic.

Why it matters

uPVC gets sold as the material you never have to think about, but the weather here has other ideas. Frames on the shaded side of a house stay damp for days after rain, and the algae that grows on them spreads along the sills and into the seals if it’s left. On busy roads through Prescot and Huyton the frames pick up traffic film on top, a grey layer that dulls the white and clings on through the rain.

A proper clean sharpens up the whole front of the house in an afternoon. Because the solution kills the algae and mould instead of smearing it around, the frames stay brighter for longer, and the seals stay in better nick without black growth working into the rubber.

My frames have gone dull and yellow. Can cleaning fix that?

It depends on the cause. Dirt, algae and traffic film make white uPVC look grey, green or dull, and a soft wash brings the colour back. Yellowing from years of sunlight is a change in the plastic itself, and no amount of cleaning reverses that. We’ll tell you straight which one you’ve got when we look at the job.

What are the green and black marks on my window frames?

The green is algae, and it loves the damp Merseyside air, especially on shaded and north-facing frames that stay wet after rain. The black flecks in the rubber seals are mould. Both are living growth, so we treat them with a uPVC-safe solution that kills them off rather than just wiping the surface clean.

Do you clean the glass as well as the frames?

Yes. There’s no sense handing back gleaming frames around dirty windows, so the glass gets cleaned as part of the job, along with the sills. Everything is rinsed down at the end so there are no streaks or residue left on the plastic or the panes.

Can a pressure washer damage uPVC frames?

Yes, which is why we don’t use one on them. High pressure can force water past the seals into the house, mark the plastic and even shift glazing beads. Frames get a soft wash instead: low pressure, the right solution and hand work on the fiddly bits. The jet wash stays on the driveway where it belongs.
