Color is emotion. In my work as a colorist and home stager, I help homeowners choose palettes that evoke warmth, stability, and welcome. However, the most beautiful color scheme in the world is rendered ineffective if it is covered in a layer of grey atmospheric grime or green algae. I often see homeowners debating expensive repainting projects because their house looks “dull,” when in reality, the paint is fine—it is just dirty. Cleaning is the “reset button” for your home’s color palette.
When clients ask how much to power wash a house, I compare it to the cost of a new wardrobe versus a dry cleaning bill. Washing is a fraction of the cost of painting, yet it achieves 80% of the visual transformation. Over time, UV light, pollen, and pollution create a haze that desaturates the color of your siding. A professional soft wash lifts this haze, revealing the true saturation of the original hue. That pale yellow becomes sunny again; that slate blue regains its depth. It restores the contrast between the siding and the trim, which is essential for architectural definition.
The Green Cast of Algae
On light-colored homes, green algae and mildew create a sickly cast. From the street, this doesn’t always look like “dirt”; it just makes the house look dingy and neglected. Subconsciously, green-tinted siding suggests dampness and rot to a viewer. It triggers a “stay away” response. removing this biological growth instantly brightens the home and makes it feel crisp and dry. For white trim, which frames the house, removing the grey mildew streaks restores the sharp, clean lines that define the windows and roofline.
Brick and Stone Vibrancy
Masonry is particularly prone to dulling because it is porous. Dust and soot settle into the texture of the brick, muting the reds and browns. Moss growing in the mortar joints breaks up the visual continuity of the wall. Power washing brick (carefully, with low pressure) cleans these pores. I am always amazed at how red the brick looks after a wash. It pops against the landscape. Clean masonry looks solid and expensive; dirty masonry looks old and tired.
The “Halo Effect” on Landscape
A clean house actually makes your landscaping look better. When the backdrop (the house) is bright and clean, the greens of the shrubs and the colors of the flowers stand out more. If the house is dirty, the whole property feels muted. It is the “halo effect”—one positive attribute (a clean house) influences the perception of the entire property. By washing the house, the walkways, and the driveway, you increase the overall visual value of the estate without planting a single new flower.
Preparing for Paint (If Necessary)
If you are planning to repaint, power washing is a non-negotiable first step. Paint cannot bond to dirt or chalky oxidation. Painting over a dirty house ensures the paint will peel within a year. A professional wash removes the “chalking” (loose pigment) from old aluminium or vinyl, creating a pristine surface for the new coat. Ideally, after washing, you might realise you don’t even need to paint, saving you thousands. But if you do, the wash ensures the investment lasts.
Conclusion
