Soft Washing vs Pressure Washing: Which Does Your Home Need?
Both clean your exterior, but they are for different surfaces. Use the wrong one and you can damage your home. Here is the simple rule.
Last reviewed June 2026
The short answer
Use pressure washing on hard surfaces like concrete, driveways, paths and brick. Use soft washing on delicate surfaces like render, painted walls, weatherboard and cladding. House walls should be soft washed, not pressure washed. We use whichever suits each surface, often both on the same job.
Pressure washing: for hard surfaces
Pressure washing (also called power washing) uses high pressure to mechanically blast dirt, oil, mould and black weathering off hard surfaces. It is the right method for driveways, concrete, paths, pavers and brick, where the surface is tough enough to take the pressure. On big flat areas we run a flat surface cleaner rather than a wand, which is what gives that even, stripe-free finish, and we detail the edges by hand.
Soft washing: for delicate surfaces
Soft washing uses low pressure plus a tailored cleaning solution that breaks down mould and algae at the source, then rinses it away. It is the safe choice for render, painted surfaces, weatherboard, cladding and anything fragile, where high pressure would crack, pit or strip the surface. This is why house washing is a soft-wash job, not a pressure-wash one. The solution does the work: it is applied at little more than garden-hose pressure, given time to break down the growth, then rinsed off gently. On the shaded, tree-lined blocks common across the Northern Beaches, that matters, because the grime on walls here is mostly living growth, shade mould and algae, not loose dirt.
Side by side
| Pressure Washing | Soft Washing | |
|---|---|---|
| Best for | Hard surfaces: concrete, driveways, paths, brick, pavers | Delicate surfaces: render, painted walls, weatherboard, cladding |
| Pressure used | High pressure | Low pressure plus a cleaning solution |
| How it cleans | Blasts dirt and grime off mechanically | Breaks down mould and algae at the source, then rinses |
| Risk if misused | Can damage soft or painted surfaces | None for delicate surfaces; too gentle for set-in driveway grime |
| How long it lasts | Until dirt rebuilds | Often longer, because it treats the growth not just the surface |
Surface by surface: what your home needs
Here is how we treat the common surfaces on a Northern Beaches home. The pattern is simple: the harder and more sound the surface, the more pressure it can safely take.
| Surface | Right method | Why |
|---|---|---|
| Concrete and driveways | Pressure washing | Tough enough for high pressure and a surface cleaner, which gives the flat, even finish |
| Brick | Depends on the brick | Hard modern brick takes pressure well; older or softer brick and mortar need soft washing |
| Pavers | Careful pressure washing | Controlled pressure so the jointing sand stays put and the pavers stay steady |
| Sandstone | Low pressure only | Soft stone that a strong jet erodes and roughens, so it gets a gentle clean |
| Render | Soft washing | High pressure cracks, pits and scars render; low pressure and solution lift the growth safely |
| Weatherboard and cladding | Soft washing | Pressure forces water behind the boards and flakes paint; soft washing does neither |
| Painted walls | Soft washing | Paint strips and chalks under high pressure; soft washing keeps the finish intact |
What happens when you use the wrong method
Too much pressure on a delicate surface causes damage that no clean can undo. Render pits and scars. Paint flakes and strips. Weatherboard lets water in behind the boards, and the damp shows up weeks later as swelling and stains. Sandstone loses its face and comes back rougher and quicker to grime up. Pavers lose their jointing sand and start rocking underfoot. These become repair jobs, not cleaning jobs, and they cost far more than the clean ever would have.
The reverse mistake is gentler but still disappointing. Soft washing a driveway with years of set-in grime and black weathering will not shift it, because that build-up needs mechanical pressure and a surface cleaner to lift. You end up with a surface that looks barely different. Around here the usual culprits are shade mould, algae and leaf-tannin staining from overhanging trees, and each one responds to the right method, not simply more force.
How to tell which your home needs
A quick way to think about it: if the surface is something you park on or walk on, it is probably a pressure washing job. If it is something you look at, like walls, render, cladding or paintwork, it is almost certainly a soft washing job. And if paint chalks onto your hand when you rub the wall, or the brick is old and soft enough to scratch with a key, treat it as a low-pressure surface no matter what it is.
What is growing on it matters too. A green film on a shaded wall is algae and mould, which soft washing treats at the source. Black, ground-in weathering on concrete needs pressure to shift. The brown staining under trees is leaf tannin, which needs the right treatment rather than a harder blast.

So which do you need?
Most properties need both. The driveway and paths get pressure washed, the house walls and render get soft washed, and the windows get cleaned separately. The skill is matching the method to each surface, which is what we assess before we start, and the quote is always free.
Common questions
Soft Washing vs Pressure Washing FAQs
What is the difference between soft washing and pressure washing?
Pressure washing uses high pressure to blast dirt off hard surfaces like concrete and driveways. Soft washing uses low pressure and a cleaning solution to safely clean delicate surfaces like render, cladding and painted walls. The right choice depends entirely on the surface.
Should I pressure wash or soft wash my house?
House walls should almost always be soft washed, not pressure washed. High pressure can force water behind cladding and strip paint and render. Soft washing lifts the mould and grime safely at low pressure, which is why house washing is a soft-wash job.
Can you pressure wash render?
Render should be soft washed, not pressure washed. High pressure can crack, pit or strip rendered surfaces. We use low-pressure soft washing on render so it comes up clean without damage.
Which is better, soft washing or pressure washing?
Neither is better overall, they are for different surfaces. The best result comes from using the right method for each surface, which is exactly how we work: high pressure for hard surfaces, soft washing for delicate ones, on the same job where needed.
What happens if you pressure wash weatherboard?
Two bad things. The jet flakes and strips the paint, and it drives water up behind the boards where it sits against the frame and shows up later as damp and swelling. Weatherboard and cladding should always be soft washed at low pressure, which lifts the mould and grime without touching the paint or letting water in.
Can you pressure wash sandstone?
Not with high pressure. Sandstone is soft, and a strong jet erodes the surface, leaving it rough, fuzzy and quicker to grime up again. We clean sandstone gently at low pressure so the stone keeps its natural face. It is one of the surfaces where the wrong method causes the most permanent damage.
Will pressure washing damage my pavers?
It can if it is done carelessly. The main risk is blasting out the jointing sand between the pavers, which leaves them loose underfoot and invites weeds into the gaps. Done properly, with controlled pressure and the right technique, pavers come up beautifully. We clean them all the time, and the skill is in the control.
Is the soft washing solution safe for gardens and pets?
Yes, when it is handled properly. We wet down surrounding plants before we start, rinse everything thoroughly afterwards, and match the solution to the surface and the job. Keep pets inside while we work and everything is back to normal once we have rinsed off. Managing this carefully is a standard part of every soft wash we do.
How long does a soft wash last compared to pressure washing?
Often longer. Soft washing kills the mould and algae at the source rather than just knocking the visible layer off, so regrowth is slower. How long it stays clean depends on the spot: shaded, tree-lined and bush-backed walls regrow faster than open, sunny ones, whichever method is used.
How do you decide which method to use on my home?
We walk the property before we start and match the method to each surface: pressure for the concrete, paths and pavers, soft washing for the walls, render and anything delicate. You get one free quote covering the lot. We also finish with a walk-around at the end, and if anything is not right we re-do it.
