House Wash, Windows and Driveway — Clapperton Street, Bentleigh

Render is why this is a soft wash and not a pressure clean. Pressure high enough to strip growth off a rendered wall will also open the surface, and an etched section never blends back in. So the growth has to be killed rather than blasted.

The walls came first, then the glazing, then the driveway. Wash the render after the windows and the windows need doing again; clean the driveway first and it collects everything that comes off above it. The render was treated at low pressure and left to work — soft washing kills growth rather than removing it on the spot, so a wall keeps clearing for a week or two. In January heat that runs faster.

• Rendered walls soft washed at low pressure
• Growth treated rather than stripped off the surface
• Windows cleaned inside and outside after the walls
• Frames, sills and tracks cleaned with the glazing
• Driveway cleaned last, once everything above was done
• Before and after photographs supplied

• Whole exterior in one visit, not three bookings
• Render surface intact, no etching or patchy sections
• Windows finished after the walls, so they stayed clean
• Driveway cleared of its own soiling and the run-off
