The right pressure for the surface
High pressure can damage paint, timber and plaster. Walls and painted surfaces get a soft wash. Pressure is kept for hard surfaces that can take it, such as concrete.
What we need from you
We use water and power on site. Please move pot plants, bins and outdoor furniture away from the area first. Exterior work depends on the weather, so we may need to reschedule if it rains.

What people ask us
Why does moss come back on Wellington paths?
Shade and moisture let it grow back. Treating the moss slows regrowth, and keeping the surface clear of leaves also helps.
Can you wash a two-storey house?
Usually, yes. Send photos showing the height and any steep ground so we can check access first.
Can you quote from photos?
Yes. We confirm the price on site if the scope turns out to be different.
