Pressure Washing in Pelentong

Four things drive the spread: surface area and condition (heavy staining doubles the time), access (upper storeys, tight side passages), method (soft washing with chemicals costs more than a quick rinse), and what is bundled (resealing, weed treatment, gutter clear-out). A cheap quote is often just a rinse with no pre-treatment — clarify the scope before comparing numbers.

Most residential pros use your outdoor tap and, for electric machines, an outdoor socket. Petrol-powered machines only need water. Some companies carry water tanks for properties without an accessible tap — ask in advance, as tank supply can add to the price. Water usage for a typical driveway job is modest, roughly comparable to a few loads of laundry per hour of cleaning.

Pressure washing uses high-pressure water and suits hard surfaces: concrete, pavers, brick. Soft washing uses low pressure plus a cleaning solution and is the right method for painted render, siding, roofs, and timber, where high pressure would strip paint, gouge wood, or crack tiles. A good pro will recommend soft washing for delicate surfaces without being asked.

Fresh oil mostly comes out with a degreaser pre-treatment plus hot-water pressure washing. Old oil that has soaked deep into concrete may only fade, not disappear — an honest pro will tell you this before quoting rather than promising full removal. Ask specifically whether stain treatment is included or extra.

Renting a machine costs a fraction of a pro visit, but consumer machines are slower, and the main risks are damage (etched concrete, stripped paint) and injury — a 3000+ PSI jet can cut skin. DIY makes sense for a small, flat concrete area. Hire a pro for two-storey walls, roofs, timber, render, or anything needing ladders or chemicals.

Expect roughly RM60-RM150 per hour for a crew with equipment, RM150-RM600 for a car porch and driveway, and RM500-RM2,500 for a full terrace-house or semi-D exterior. Klang Valley rates are the benchmark; other states run 20-30% lower.

Every 6-12 months for most homes. Year-round humidity plus daily wet-dry cycles grow black mould and algae on porch tiles and boundary walls quickly, and shaded north-facing surfaces may need attention every 6 months with an algaecide to hold results.
