Choosing the right clean
Start with the surface. Then the stain.
Traffic grime, mould in shaded corners, mortar left by earlier work and white salt deposits can all mark a wall. They need different treatment. The brick or stone, the condition of the joints and any earlier cleaning matter as much as the stain.

What we clean
- Mortar smears and splashesResidue left by building or repair work. The brick type and mortar stain determine whether a specialist cleaner or suitable acid wash can help.
- White salt marksEfflorescence appears as water carries salts to the surface. Fresh deposits can weather away; persistent marks call for a closer look at the moisture source.
- Grime, algae and mouldDirt and growth on shaded walls, fences and paths. Cleaning should lift the deposit while preserving the brick face and surrounding joints.
- Sandstone bases, steps and wallsStone needs its own assessment. Soft or weathered sandstone should not be treated like robust clay brick.

How it’s done
A cleaner wall. Its character intact.
Low-pressure washing, a cleaner suited to the stain or a suitable acid wash each have a place. The gentlest effective approach comes first.
Inspect the surface and the stain
Identify the brick or stone, check the joints and look at the marks. Recurring moisture and earlier treatments can change what is appropriate.
Test the method, agree the finish
A small, discreet trial area shows how the surface responds and what can reasonably be removed. The aim is a cleaner wall with its character intact.
Protect, clean and check
Nearby windows, metalwork, planting and runoff are protected. The method is applied, then the finish checked, rather than raising the pressure to chase every mark.
Acid washing, older materials and repairs
- When acid washing suits
Acid washing can help remove mortar residue from suitable clay brick. It is not a general-purpose clean: the wrong product or method can damage the face, affect mortar colour or leave new stains. Brick-specific guidance and a small trial area help establish whether it is appropriate.
- Older brick and sandstone
Strong acid or aggressive pressure can permanently alter soft brick, coloured joints and weathered stone. A treatment meant for clay brick is never assumed to suit sandstone.
- Cleaning alongside repairs
Cleaning may form part of repointing or tuckpointing work. The sequence depends on the wall, the repair and the products used. Fragile joints may need attention first, and newly finished mortar needs appropriate time before any final clean.
Pricing
Plan the clean.
An inspection and, where appropriate, a trial area establish the method, the expected finish and the scope.
Priced for your wall
Brick cleaning has no single typical price: the damage, the wall and the access set the work. We explain the proposed repair, and inspect where it needs a closer look, before you decide.

What shapes the quote
Area and condition
How much needs cleaning, the brick or stone type, and the condition of the faces and joints.
The marks themselves
The type and depth of staining, any previous treatment and the result of a trial clean.
Access and protection
Height, room to work, nearby surfaces and plants, and how water and runoff are managed.
Other work needed
Mortar repairs or a moisture issue may need attention as part of the wider job.
Will cleaning damage my brick?
Unsuitable chemicals or pressure can damage brick faces and mortar, particularly on older walls. The surface condition, brick-specific guidance and a trial area help choose a suitable method. Some weathered surfaces or ingrained marks are better left than aggressively cleaned; we discuss the likely result before proceeding.
Why does the white powder keep coming back?
Efflorescence is salt carried to the surface by water. It can be temporary on new masonry and weather away, but repeated deposits may point to continuing moisture from drainage, leaks or another source. Cleaning the visible salt does not resolve that source, so the marks can return.
What if the wall has already been acid washed or pressure cleaned?
Tell us what was used, when it was done and how the surface changed. Earlier treatment can affect the next step. Fresh staining, roughened faces or damaged joints need assessment before more cleaning; another acid wash may make the problem worse.
Why do quotes for the same wall differ, and how do I compare them?
Quotes can cover different work. One may rake out only the loosest mortar while another takes every joint back to a sound depth, and the mortar mix, how the finish is matched, access and scaffolding, and cleaning down all change the price. Compare quotes on the same area and finish, and ask each what is included and what is not. Any scaffolding your job needs is included in our quote.
How soon can you start, and how long will the work take?
We start as soon as we can once you accept the quote. As a guide, a small repair, a single lintel or most crack stitching takes a day or two, repointing a brick front fence one to two days, and tuckpointing a single-storey brick front about a week. Larger or higher walls, scaffolding and wet weather add time. Tell us about any renovation deadline when you enquire and your quote will give a realistic start date and duration.
Does a heritage-listed home need approval for brickwork repairs?
Check the listing and the proposed work before starting. For a local heritage item or conservation area, ask your council about approval or a maintenance exemption. State Heritage Register properties also have Heritage NSW requirements. Like-for-like work is not automatically exempt; the relevant conditions still need to be met.
