Why render gets dirty
Modern renders like K-Rend, monocouche and Weber are excellent at insulating and protecting a home, but their porous surface is exactly what algae, lichen and fungi like. In the damp North West climate that shows up as green staining, red streaks and black patches, usually worst on north-facing walls and under window sills.
Left alone, the growth does not just look bad. It holds moisture against the render and can penetrate it, which is how a cleaning job turns into a repair or repainting job.
Soft wash: what it does
- No damage: low pressure cleans without blasting the render surface
- Kills the root cause: a professional biocide stops the stains coming back quickly
- Cost-effective: cleaning is a fraction of the cost of repainting
- Instant kerb appeal: the original bright finish comes back within days

- You are thinking about repainting because it looks tired

Why choose Hydro Cleanse for render cleaning in Blackburn?
Blackburn and Darwen sit against the West Pennine Moors, and the rain and shade do rendered walls no favours. The K-rend estates around Feniscowles, Mellor and Wilpshire show green algae on the north side within a few years, and the pebbledash semis and terraces across the town collect black staining and grime in the rough surface.
We clean render with a low-pressure soft wash. A biocidal solution is applied across the whole wall, left to kill the algae, mould and lichen at the root, then gently rinsed off. No pressure washer, so there is no cracking, no blown pebbles and no water forced behind the render.
From Darwen and Rishton to Great Harwood, Oswaldtwistle and Clayton-le-Moors, we cover the whole of the Blackburn area for homeowners, landlords and businesses. Fixed quote before we start, before and after photos when we finish, and we are only twenty minutes away in Rossendale.
A follow-up biocide treatment keeps the growth away for three to five years on most walls. Shaded and north-facing elevations near the moors may need re-treating sooner, and we tell you honestly what to expect for your house.
For the full method, render types and pricing see our render cleaning service page. We also offer roof cleaning, gutter cleaning and driveway cleaning on the same visit, and commercial render cleaning for business premises.

What our customers say
“Peter from hydrocleanseuk came to work his magic on our large gable-end wall this week (the 10 year old K Render was an eyesore, streaked with multicoloured lichen and algae) - what a transformation! It is now pristine and looking like new! He then tackled our neglected roof tiles, filthy with years of dirt and covered with mossy bits, plus a spotty multitude of white lichen blobs! That is now also beautifully restored and good as new - plus our gutters are sparkling too! Both the walls and roof were then treated with 'Softwash' - a mild biocide - which will ensure that the great results will last a few years to come. Peter and his assistants worked impressively hard throughout and also cleaned up fully upon completion - our patio, paths, driveway, windows and drains have all been left far better than they've been for ages! Communication with Peter has been excellent from start to finish, via frequent texts - from the initial quote, through all the work involved, to the final clean-up and payment (which was definitely value for money!) Please see the before and after photos and judge for yourselves - it's been a great investment in caring for our home! It has been a pleasure having Peter and his team working on our premises and we would not hesitate in recommending them 100%.”
“Had my k rend walls and garage cleaned and could not be happier with the results. All come up like new and the stone copings look great again. Professional service and highly recommended.”
“My house is Victorian with a complicated roof structure.Peter managed to reach every nook and cranny to remove the moss which had badly accumulated on the North elevation of the building.The final result is impressive and I am sure will have added to the value of the house when we come to downsize next year. A difficult job well done.Thanks”
Blackburn render cleaning FAQs
Can you pressure wash render?
You should not. High pressure blasts the surface off render and forces water behind it. We only use low-pressure soft washing with a biocide, which cleans without damage.
How long do the results last?
Typically two to three years before any growth starts to show again, longer on sunny elevations. Regular re-treatment keeps it clean indefinitely.
Will the chemicals damage my plants or lawn?
We protect and pre-wet plants and lawns before treatment and rinse them afterwards. The products we use are applied at low pressure and controlled carefully.
Do you clean painted render?
Yes. Painted and smooth render is cleaned the same way, with a gentle soft wash that does not strip the paint.
How much does render cleaning cost?
It depends on the wall area and the level of staining. Send photos and your postcode and we will give you a fixed quote, usually the same day.
