House Washing in Central Coast

What pressure cleaning in Central Coast actually involves

Dirt gathers where the rain doesn't reach. Look under the eaves, at the tops of windows, and on any wall behind a porch or veranda. Those surfaces stay sheltered and keep the grime, salt and growth that the open parts of a wall lose in the next storm, and on a shaded side it shows as grey-green streaks running down from the gutter line.

What to tell the provider

The wall material decides the method. Painted weatherboard is washed at low pressure, because a strong jet lifts paint and older paint lets go first. On brick, the lichen that likes lime grows on the mortar between the bricks rather than on the clay bricks themselves, so the joints are what need the attention. Rendered walls show dark streaks where water runs off sills and roof edges. Central Coast Council's water-wise rules allow house walls to be washed at any time of day, with a trigger-nozzle hose or a high-pressure, low-volume cleaner.

Before any house is washed, the provider needs to know what the walls are made of. Fibro sheeting on homes built between 1940 and 1990 may contain asbestos, and high-pressure water on asbestos products is prohibited in New South Wales, whoever is holding the hose. If you aren't sure what your cladding is, say so in the enquiry.

House Washing in Central Coast — common questions

Will washing damage my paint?

It can if the pressure is too high. Paint on older weatherboard lifts first, which is why painted walls are washed at low pressure throughout.

My house has fibro walls. Can they be washed?

Not with a pressure cleaner if the sheeting contains asbestos, and sheeting on houses built before 1990 may. The provider should establish what the material is before quoting; a website can't tell you.

Where should I look for mould first?

Under the eaves, above the windows and on walls sheltered by a porch or veranda. Rain doesn't rinse those surfaces, so dirt and growth build up there before anywhere else.
