Fence & Retaining Wall Cleaning on the Northern Beaches

Q: Do you offer fence & retaining wall cleaning across the whole Northern Beaches?

Yes, in all 39 suburbs from Manly, Fairlight and Clontarf to Palm Beach, and west to Terrey Hills and Duffys Forest. Jobs are grouped into weekly runs by area so we are near you most weeks.

Q: How much does fence & retaining wall cleaning cost on the Northern Beaches?

Every price is on request and fixed in writing. We measure from aerial imagery, test where needed and send one figure within a business day. Call 0494 810 609 or use the form.

Q: Can you clean a Colorbond fence without stripping the finish?

Yes. A mild biocide and a low-pressure rinse remove the growth; pressure washing is what dulls the coating, so we do not use it.

Q: How often is fence & retaining wall cleaning needed on the Northern Beaches?

It depends on whether you are on the ocean front, beside a lagoon, on the Pittwater side, harbourside, on a hillside street or on the bushland plateau. The table on this page gives our usual intervals for each.

Q: Will the run-off from fence & retaining wall cleaning reach the lagoons or beaches?

No. Drains are bunded, rinse water is captured or sent to garden, and sealed or commercial sites are vacuum-recovered. Almost every Northern Beaches street drains to a lagoon, Pittwater, Middle Harbour or a beach.

Q: Is the work guaranteed?

Yes. If anything we quoted is not clean at handover, we return within seven days and redo it free. We carry $20 million public liability.

Fences and retaining walls in sandstone, block, render, timber or Colorbond cleaned with the method each material needs. Every suburb from Manly to Palm Beach and out to Duffys Forest.

On the Northern Beaches

Where fence & retaining wall cleaning matters most on the peninsula

Where we do it most: Seaforth, Fairlight, Beacon Hill, Collaroy and Collaroy Plateau
Council: Northern Beaches Council
Coverage: All 39 Northern Beaches suburbs
Run-off: Captured on every job
Pricing: On request, fixed in writing

Retaining walls are part of almost every steep block on the beaches, from the harbour slopes of Seaforth and Fairlight to the terraces of Beacon Hill and Collaroy Plateau; Colorbond fences by the lagoons go green within a couple of years.

The Northern Beaches packs surf beaches, four coastal lagoons, the Pittwater estuary, Middle Harbour and national park bushland into one council area, so fence & retaining wall cleaning is never one method for everyone. The table shows how we adjust it by condition and how often it is usually needed.

Conditions	Suburbs	What we are dealing with	How often
Ocean-front and first-ridge	Manly, Queenscliff, Freshwater, Curl Curl, North Curl Curl and Collaroy and 6 more	Salt film on glass within a fortnight, rust-run from every fixing, and black cyanobacteria on the shaded south and east walls	every 6 to 9 months
Lagoon and estuary	Dee Why, Narrabeen, North Narrabeen and Warriewood	Green algae and black mould on the shaded elevations, lichen on stone and pavers, and moss in any joint that stays damp	every 9 to 12 months
Pittwater waterfront and slopes	Bayview, Church Point and Clareville	Tannin and leaf-litter staining, lichen and moss on sandstone, green film on timber and pool surrounds, and mould under deep eaves	every 12 months
Plateau and bushland edge	Elanora Heights, Ingleside, Terrey Hills, Duffys Forest, Belrose and Davidson and 3 more	Gutters full of eucalypt leaf and bark, moss and lichen on shaded roofs, paving and tennis courts, and red clay staining on concrete after storms	every 18 to 24 months
Harbourside Middle Harbour	Fairlight, Balgowlah Heights, Clontarf, Seaforth and North Balgowlah	Mould and algae on render and painted brick, lichen on sandstone retaining walls, and tannin staining from the tree canopy over paths and driveways	every 12 months
Hillside and village	Balgowlah, Cromer, Beacon Hill, Allambie Heights, Collaroy Plateau and Bilgola Plateau	Salt haze on glass that faces the ocean, mould on the shaded render, and dull, lichen-spotted concrete driveways and paths	every 12 to 18 months

Our method in the Northern Beaches

How we do it, and what we protect while we work

Sandstone and block walls get a biocide and brush, rendered walls a soft wash, timber an oxygenated cleaner, and Colorbond a mild wash that keeps its gloss. Mortar joints are never hit with high pressure.

Neighbour-side planting and surfaces protected where the fence is shared

Garden beds at the base pre-wetted and sheeted

Weep holes kept clear so the wall drains after cleaning

Run-off captured where it would reach the street

Google review · Sandstone Cleaning

I recently had my brick pavers cleaned by Prestige Standard and I couldn't be happier with the results. The team was professional, punctual, and paid great attention to detail. My pavers went from looking dull and stained to fresh and almost brand new again.
