Pressure Washing in Delmas

Move cars off the driveway, clear pots, furniture, and toys from the work area, close all windows and doors, and cover or flag anything fragile like garden lights. Point out hairline cracks, loose pointing, or flaking paint in advance — pros will work around known weak spots but cannot see them under grime.

Light rain is usually fine — surfaces are already wet. Pros avoid freezing temperatures (ice risk on cleaned surfaces and damaged equipment) and heavy storms. In hot dry regions, local water restrictions can limit or ban high-volume outdoor cleaning during drought periods, so check the current rules before booking.

Yes. Too much pressure or the wrong nozzle can etch concrete, blast mortar out of brick joints, splinter timber decking, strip paint, and force water behind siding or render. Roof tiles are especially vulnerable. Ask the pro what PSI and nozzle they plan to use per surface, and whether they soft wash delicate areas.

High-pressure washing damages most roof coverings — it strips granules from asphalt shingles, cracks and dislodges tiles, and can force water under the covering. Roof cleaning should be done by soft washing or manual moss removal plus a biocide treatment. If a company proposes blasting your roof at full pressure, choose someone else.

It is one of the cheapest kerb-appeal upgrades before selling or renting out a property. Estate agents consistently list exterior cleaning among the highest return-on-cost pre-sale jobs because it changes first impressions for a few hundred, not a few thousand. It will not fix structural issues, but it makes photos and viewings noticeably better.

Most pros charge either by the hour or by surface area. A single driveway or patio is typically a 1-3 hour job at the low end of a pro's minimum call-out, while a full house exterior wash costs several times more. Get the quote broken down by surface (driveway, walls, deck, roof) so you can drop items to fit your budget.

It depends on the municipality's current restriction level. Cape Town's higher restriction levels have banned hosing paved surfaces with potable water, while low-volume high-pressure equipment or non-potable water may still be allowed. Ask the contractor to confirm compliance for your municipality before booking.

Expect roughly R350-R750 per hour for a crew with equipment, R500-R1,800 for a standard driveway, and R1,500-R5,000 for a full house exterior depending on size. Johannesburg and Cape Town sit at the top of the range.
