Pressure Washing FAQs

What is pressure washing?

Pressure washing is the use of high-pressure water to remove dirt, grime, mold, algae, and other contaminants from external surfaces. At Horand Industry, we use commercial-grade equipment and cold water to safely and effectively clean concrete driveways, pathways, patios, and house exteriors.

Is pressure washing a good way to prepare concrete for sealing, resurfacing, or epoxy flooring?

​Yes. Pressure washing is an essential step in preparing concrete for sealing, resurfacing, or applying epoxy flooring. It removes dirt, dust, mold, algae, oil, and other contaminants that can prevent coatings from adhering properly.

What surfaces can be pressure washed?

We clean a wide range of surfaces, including:

• Concrete driveways, paths, and patios

• Brickwork and rendered walls

• Exterior house cladding and fencing

• Pool surrounds and retaining walls

Our team assesses the surface before starting to ensure it can withstand the pressure safely.

Do you use hot or cold water?

We primarily use cold water for pressure washing. Cold water is highly effective for most cleaning tasks, including removing dirt, algae, and general grime, and is safe for all standard exterior surfaces.

​Do you use chemicals or bleach?

​Yes, when required. We may apply commercial-grade bleach to remove tough stains, mold, or algae, particularly on concrete or shaded areas where organic growth is common. Our team carefully measures and applies bleach to ensure safety and prevent damage to surfaces, plants, or surrounding areas.

​Is pressure washing safe for my house and landscaping?

Yes, when performed by professionals. At Horand Industry, we adjust the pressure and nozzle type depending on the surface. For delicate areas such as painted walls, timber, or soft brickwork, we use lower pressure settings and targeted cleaning solutions to avoid damage. Plants and landscaping near the work area are protected during cleaning.

How often should I have my surfaces pressure washed?

Frequency depends on the surface, location, and exposure to dirt or organic growth:

• Driveways and concrete paths: every 12–18 months

• House exteriors: every 18–24 months, or sooner if mold, algae, or dirt buildup is visible

• High-traffic or shaded areas: may require more frequent cleaning

Regular pressure washing helps maintain your property’s appearance and extends the life of surfaces.

Will pressure washing remove stains and oil from concrete?

Pressure washing can remove surface dirt, moss, algae, and many fresh stains. However, some old or deeply set stains, such as long-standing oil or chemical marks, may not be completely removable. In those cases, we aim to significantly improve the appearance of the surface and can recommend additional treatments if necessary.

Can pressure washing damage my concrete or paint?

​If done incorrectly, pressure washing can damage surfaces. Horand Industry uses commercial-grade equipment and adjusts water pressure to suit the material being cleaned. Concrete, brick, and hard surfaces are generally resilient, while delicate painted surfaces or soft timber require lower pressure and controlled cleaning techniques to prevent damage.
