Cladding Cleaning

Low-pressure soft washing for uPVC, composite, timber-effect and painted cladding in Prescot, Knowsley and St Helens. Algae and black streaks lifted without cracking a single panel.

What we clean

Blastaway Pressure Washing Services soft washes exterior cladding on homes across Prescot, Knowsley, St Helens and Liverpool:

  • uPVC cladding and shiplap boards
  • Composite and timber-effect cladding
  • Painted and coated panels
  • Garden rooms, dormers, porches and extensions

Cladding picks up the same problems everywhere on Merseyside: green algae creeping up from the bottom edge, black streaks running down from trims and sills, and a general dullness on walls that sit in shade and never properly dry out. The newer estates around Prescot and Whiston have plenty of composite and timber-effect boarding, and it greens up just as readily as the older uPVC.

How we clean it

  1. Look before we spray. We identify the cladding type and check its condition, because uPVC, composite and painted boards each want a different solution and dwell time.
  2. Prep the area. Loose dirt and cobwebs are brushed off, and any plants below the wall are wetted down and covered.
  3. Apply the soft wash. A low-pressure application works the cleaning solution across the panels so it breaks down the algae and grime at the root instead of smearing it about.
  4. Dwell, then rinse. The solution is given time to work, then rinsed off thoroughly, leaving no residue on the boards and no water behind them.

Why it matters

Grubby cladding drags the look of the whole house down, but the damage side matters more. Algae and black streaks hold moisture against the boards and joints, and a wall that stays damp weathers faster than one that sheds water. The temptation is to go at it with a jet wash, and that’s the one thing cladding can’t stand: high pressure cracks panels, lifts paint and pushes water into the cavity behind. Soft washing gets the growth off and keeps the boards intact, which is why it’s our standard method for cladding, render and anything else with a delicate face. The pressure washing stays on the driveways and patios where it does its best work.

Cladding cleaning FAQ

Straight answers to the things people ask us about cladding cleaning around Prescot and Merseyside.

Is soft washing safe for cladding?

It’s the safest way to clean it. Soft washing uses low pressure and a cleaning solution matched to the material, so the algae and streaking break down and rinse away without panels cracking, paint stripping or water being forced behind the boards. A high-pressure jet does none of those things kindly.

What types of cladding do you clean?

uPVC and shiplap boards, composite, timber-effect and painted or coated cladding, on houses, extensions, garden rooms and dormers. Whatever the material, it gets looked at first and cleaned with a method that suits it.

Will the clean damage the panels or the finish?

Not the way we do it. Most cladding damage happens when someone turns a pressure washer on it: cracked panels, stripped paint and water driven into the joints. We lead with low pressure, keep the lance well back from any seams, and only step the pressure up on a surface that can genuinely take it.

How much does cladding cleaning cost?

It depends on how much cladding there is, what it’s made of, how green it’s gone and how easy it is to reach.

Do you do cladding cleaning near me?

We’re based in Prescot and work across Knowsley, St Helens, east and south Liverpool, Widnes and the surrounding towns within roughly 15 miles. Send us your postcode and we’ll confirm we cover your area.

How often does cladding need cleaning?

A yearly clean keeps most cladding looking right, and shaded or north-facing walls that green up quickly are worth keeping on that schedule. Because soft washing kills the algae rather than skimming the surface, the panels stay cleaner for longer between visits.
