Last updated: 22 September 2026 ![Worker using a rotary surface cleaner on a driveway](/images/featured/worker-pushing-a-rotary-surface-cleaner-across-a-m.webp) ## The Equipment, and Why It Matters Two tools do most of the work in a pressure washing [/pressure-washing/ →](/pressure-washing/) job. **The high-pressure jet** runs at roughly 120 to 150 bar with a fan nozzle. It’s used for walls, edges, corners and anywhere a machine can’t sit flat. The pressure and the distance from the surface are both adjustable, and both get set per surface rather than left at maximum. **The rotary surface cleaner** is a flat housing with spinning jets underneath. It’s used on open areas like driveways and patios because it covers evenly. A hand-held wand on a large driveway leaves visible stripes where passes overlap unevenly — the rotary head is what prevents that. For height, telescopic extension poles reach upper walls and eaves safely, which avoids putting a ladder on a wet surface. ## Which Surfaces Are Suitable **Handles it well:** cement driveways, interlocking pavers, brushed concrete, unglazed outdoor tile, rendered perimeter walls, brick, drains and outdoor stairs. **Needs care:** painted render (pressure can strip paint), older cement with existing cracks, and pavers with loose or washed-out joint sand. **Usually avoided:** timber decking at high pressure, soft sandstone, and anything with failing grout or mortar that the water would blow out. If you’re unsure what your surface is, that’s exactly what the free on-site estimate is for. Guessing on a driveway is an expensive way to learn. ![Perimeter wall being jet washed](/images/content/perimeter-wall-being-jet-washed-with-spray-and-run.webp) ## The Order of Work 1. **Clear the area.** Cars moved, plants and pots shifted, mats lifted, anything loose put away. 2. **Protect what needs it.** Door thresholds, power points, garden beds and anything that shouldn’t take direct spray. 3. **Pre-wet and test.** A small patch first, checking the surface reaction before committing to the full area. 4. **Wash top down.** Walls before floors, so run-off lands on surfaces not yet cleaned. 5. **Rotary pass on open areas.** Overlapping passes in one direction for an even finish. 6. **Detail edges and joints.** Hand wand along walls, steps, kerbs and awkward corners. 7. **Treat shaded areas.** Algae biocide applied once the surface is clean. 8. **Clear the run-off.** Drains checked and flushed so silt doesn’t settle and block them. ![Cleaned patio and driveway drying in the afternoon sun](/images/content/cleaned-patio-and-driveway-drying-in-afternoon-sun.webp) ## What Results to Expect Realistic expectations save disappointment, so here’s the honest version. **What comes off:** algae, moss, general grime, mud, mildew staining and most surface dirt. The colour of the original surface usually returns, which is often a surprise to people who’d forgotten what shade their pavers were. **What may not:** deep oil stains soaked into porous concrete, rust marks from metal furniture, paint spills and permanent discolouration from long-standing planters. These need separate treatment and sometimes don’t fully clear. > **A note on joint sand** > > On interlocking pavers, washing removes some of the sand in the joints along with the moss. That’s normal. Re-sanding afterwards keeps the pavers stable and slows the next round of growth. ## Timing and Bundling Most Ipoh homes do this every 6 to 12 months, ideally before the heavy monsoon rain rather than during it. Stretching that interval is mostly a matter of preventing green algae and mould on car porches [/guide/prevent-green-algae-mould-car-porches/ →](/guide/prevent-green-algae-mould-car-porches/) between washes. If you’re booking anyway, bundle the windows into the same visit. The crew is already on site with water and access equipment, so doing the glass at the same time costs less than a separate call-out later. ## Getting Ready for the Visit A pressure washing job runs faster when the area is ready, and there are a few things only you can do. **Move the cars.** Obvious, but it’s the most common delay. Somewhere off the driveway for the whole visit, not just the start. **Shift pots, mats and furniture.** Anything sitting on the surface leaves a shadow if it doesn’t move. Plants near the work area are worth relocating too. **Close windows and doors on the working side.** High-pressure spray finds gaps that rain never does, and a fine mist carries further than people expect. **Point out the fragile things.** Outdoor power points, a garden light, a section of render that’s already crumbling, a downpipe that’s loose. Knowing in advance means we work around them. **Expect mess during, not after.** Washing lifts a lot of material onto surrounding surfaces mid-job. It gets rinsed down as part of the work, so the middle of the process looks worse than the start. **Allow drying time.** Wet surfaces stay slippery until they dry, and in Perak’s humidity that takes longer than you’d think on a shaded porch. Plan to keep children and older family members off it for a few hours. Guide FAQs ## Questions people also ask Will pressure washing damage my tiles or pavers? Not at the correct pressure and distance. Damage comes from using maximum pressure on every surface regardless of material. We match the setting to the surface and test a small area first. Can you clean high perimeter walls? Yes, using extension tools for reach. Most residential walls are handled without scaffolding. How long does a driveway take? Typically a few hours, depending on size and how much build-up there is. Heavily shaded surfaces with established moss take longer than open ones. ### Still have a question?
