Brick, concrete, stone steps and walls in sound condition are cleaned with a high-pressure jet, which strips dirt, moss and grime from hard surfaces. Bin stores and concrete yards, which collect grease and food waste, are washed the same way.
Render, painted masonry and timber cladding can be damaged by high pressure, so they are soft washed. A biocide solution goes on at low pressure, is left to act on algae, mould and lichen, then is rinsed off gently.

Low-pressure cleaning to lift algae before the timber is treated or stained.
High-pressure washing of concrete areas around commercial and shared buildings.
Questions people ask
What does pressure washing cost?
It depends on the surface, the area in square metres, the height of the wall and how heavy the staining is. Soft washing render and washing a concrete yard take different amounts of time.
Will pressure washing damage my render?
High pressure can damage render, which is why render is soft washed at low pressure. Mention any parts that are cracked or sound hollow when you ask.
Why is the wall still slightly green after cleaning?
After a soft wash the treatment carries on working. Remaining staining often fades over the following weeks as the growth dies back.
Can paint, graffiti and rust stains be washed off?
They need different treatments, and some may not come off with water alone. Send a photo of the mark and the surface it is on.
