01
Pressure washing vs soft washing
Pressure is for hard surfaces (concrete, pavers, unpainted masonry). Everything else needs soft wash. Using 3,000 PSI on painted render is a quick way to need a repaint.

Home Services
Exterior cleaning spans pressure washing concrete, soft-washing rendered walls, clearing gutters, and cleaning solar panels. Pricing depends on surface area, access, and the right technique. Pressure-washing rendered walls or painted weatherboard can strip the finish and cost thousands to repair.
For delicate surfaces (paint, render, roof), soft-washing with low pressure plus mild chemicals is standard. High-pressure is for concrete, pavers, and unpainted masonry only.
What to look for
What separates a good exterior cleaning job from a bad one
The differences between quotes usually come down to a few things. None are visible on day one, and all show up later.
02
Solar cleaning increases output
A dirty panel array can lose 10–25% of output, worth real money over a year. Clean before summer peak production.
03
Working at heights
Legally, work above 2m needs height-safety training and equipment. Cheap quotes skipping this aren't insured if something happens.
04
Gutter guards
Gutter guards reduce cleaning frequency but aren't maintenance-free. Flush still needed every 2–3 years.
05
Damage from DIY
Hired pressure washers are the most common cause of stripped render and ruined window seals. The labour cost of a pro is often less than fixing DIY damage.

Quotes well below the entry tier usually skip prep work or use lower-grade product. Quotes above the premium tier are worth asking why. Use this as a fairness check, not a bargain hunt.

What affects your quote
What affects your quote
A few factors do most of the work. Use them to decode why two quotes for “the same job” can be hundreds apart.
Area & surface
Concrete pressure-washes fast; render and weatherboard soft-wash slower. Walls also need chemical dwell time.
Height / access
Two-storey jobs need harness, scaffold, or ladder stand-offs. Adds 30–60% to flat-rate quotes.
Condition
Heavy moss, lichen, and oil stains need chemical pre-treatment and a longer dwell, which is time billable.
Water access
Jobs without nearby tap access can take longer; some operators charge a surcharge or bring water tanks.
