The work
What we clean.
Grime, mould in shaded corners, old mortar smears and white salt deposits each need a different treatment, so we work out what the marks are before cleaning.
Recognise your wall? Send us a photoMortar smears and splashes
Residue 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 marks
Efflorescence 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 mould
Dirt 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 walls
Stone needs its own assessment. Soft or weathered sandstone should not be treated like robust clay brick.

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.
Before work starts
Heritage checks before cleaning brick
We start with the gentlest method that works and a small trial area, because the wrong product can mark old brick and sandstone for good. Check the address with the council before an older wall is cleaned.
How to check heritage requirementsNo heritage conservation area
None of the councils’ local environmental plans maps a heritage conservation area inside this suburb. Individual heritage items and other property controls can still apply.
Check if your home is a heritage item
Some homes in St Leonards are listed heritage items on the councils’ heritage maps. If yours is one, the work goes through the council’s heritage process, inside a conservation area or not, so check your address on the map before work starts.

Willoughby City Council: the approval route
Willoughby City Council says like-for-like minor or maintenance works on local heritage items or buildings in heritage conservation areas may not need a development application, but you may need to request a local heritage exemption and get written confirmation before starting. Willoughby DCP Part H adds that mortar for repointing should match the colour, texture and mix of the original, noting old mortars were usually lime-based.

Lane Cove Council: the approval route
Lane Cove Council’s planning rules let minor and maintenance work on a heritage home go ahead without a development application, but only once the council has confirmed in writing, before work starts, that the work is minor and won’t harm the home’s heritage significance.

North Sydney Council: the approval route
Maintenance on heritage items or properties in heritage conservation areas can be approved without a development application through Council’s Heritage Maintenance approval, if Council is satisfied the work is minor, uses like-for-like materials and won’t harm heritage significance. The enquiry form lists repointing of masonry and brickwork as a small-scale work.
