Northern Beaches
Retaining wall cleaning on the Northern Beaches
The Northern Beaches is built on slopes, and almost every block from Manly to Palm Beach has a retaining wall. Sandstone and sleeper walls near the beach collect salt and sand, and walls on bushy blocks grow moss. We clean each one at the pressure its material can take.
Retaining walls hold back wet soil, so the back face is damp all the time. Water seeps through, carries salts and tannin to the front, and feeds mould and moss. On a sloping block they're often the biggest surface you see from the house.
We treat the growth, then clean the wall at the pressure its material can take: low for sandstone and render, firmer for block and brick in good condition. Weep holes are cleared so water can drain, and garden beds are protected.
Local detail
Retaining wall cleaning across the Northern Beaches
What we see in suburbs on the Northern Beaches:
- Narraweena: Sloping blocks mean long driveways, stairs and retaining walls, and the downhill side of the house usually stays damp and shaded.
- Beacon Hill: Roofs grow lichen on the shaded slopes, and gutters fill faster.
- Balgowlah Heights: The homes are generous: two and three storeys, large decks, pools set into the hillside and long runs of sandstone retaining wall.
- Elanora Heights: The suburb runs along the ridge between Mona Vale Road and the lake, with homes on sloping bush blocks and views over the water.
- Freshwater: Blocks slope towards the beach, so many homes have stairs, retaining walls and terraced gardens, and the lower side of the house often stays damp.
- North Balgowlah: It's a suburb of decks, retaining walls and big gardens.
How often
For retaining wall cleaning, plan on near the water, every 12 to 18 months; under trees, every 12 months.
What affects the quote
- Bush debris: gutters and roofs may need clearing before washing.
- Leaf litter: tannin stains and moss need treating, not just washing.
- Steep access: carrying gear down stairs and running long hoses adds time.

Nathan did a great job washing the external sides of our house. The weatherboard was dirty and had cobwebs. Nathan went above and beyond our expectations, the house was perfectly clean and all the cobwebs were gone.
Nathan did an incredible job at my home cleaning all my outdoor paving areas. He even washed some extra areas of my house free of charge and his price was very reasonable. He's a lovely fella and was prompt, friendly and professional. I highly recommend Nathan's services.
Nathan just completed a pressure wash of our travertine pavers under our alfresco area, around the pool and the sundeck. What an absolutely fantastic job. Nathan is punctual, knowledgeable, polite and left our place neat and tidy. We will certainly be calling him back on a regular basis and can highly recommend him.

Talk to Nathan directly. He quotes and attends every job himself.
Do you offer retaining wall cleaning everywhere on the Northern Beaches?
Yes. We cover all 42 suburbs listed above from our base in Elanora Heights.
Can you clean a sandstone retaining wall?
Yes, at low pressure so the face of the stone isn't eroded.
What is the white powder on my retaining wall?
Usually efflorescence, salts carried out of the wall by water. It can be treated and cleaned off, but it returns if water keeps moving through.
Can timber sleepers be cleaned?
Yes, at low pressure so the timber doesn't fur up.
Will cleaning damage my plants?
We cover or rinse plants and direct run-off away from beds.
Do you clean the neighbour's side of the wall?
Only your side, unless the neighbour agrees.
