Sydney's largest concentration of mid-rise strata on the peninsula: 1960s to 1990s walk-ups along Howard and Oaks Avenues, beachfront towers on The Strand, the Pittwater Road high-rise precinct, and 1950s cottages on the Dee Why Parade slopes. Most of what we clean here dates from 1950s cottages, 1960s to 1990s walk-ups, 2010s towers, on sand flats around Dee Why Lagoon with the Dee Why Head sandstone to the north.

We work around Dee Why Beach and the Strand, Dee Why Lagoon, Dee Why Head and the Long Reef aquatic reserve and Pittwater Road town centre and the new Meriton towers, on streets such as The Strand, Howard Avenue, Oaks Avenue, Pacific Parade and Dee Why Parade. The defining exterior problem is black balcony soffits and streaked render on the walk-ups, salt and rust on The Strand towers, and oil-stained, algae-slick basement car park ramps.

Homes around Narrabeen Lagoon, Dee Why Lagoon, Curl Curl Lagoon and Manly Lagoon sit in still, humid air with less salt than the ocean front but far more biological growth. Walls stay damp long after dawn, so algae and mould rather than salt are the enemy, and run-off control matters more than anywhere because the lagoons are the receiving water.

Field note from Dee Why. Dee Why's 1970s walk-ups on Howard Avenue were built with painted concrete balconies and no drip grooves, so every balcony soffit goes black; cleaning them properly is a soft wash from a pole, not a pressure job from the balcony below. Nathan G, Founder

Planning and site constraints we check in Dee Why:

Dee Why Lagoon flood-planning area across the town centre
Coastal hazard mapping along The Strand
Long Reef Aquatic Reserve off Dee Why Head

Run-off. Anything washed off a Dee Why property ends up in Dee Why Lagoon and Dee Why Beach unless it is stopped at the kerb. Northern Beaches Council enforces the NSW EPA rule that wash water, detergent and sediment stay out of stormwater, so we bund drains, capture run-off and vacuum-recover on sealed or commercial sites. More in our stormwater guide.

Maintenance in Dee Why

How each surface is cleaned here, and how often

Intervals are for lagoon and estuary conditions. In Dee Why we usually recommend soft wash every 9 to 12 months, stone and paving every 12 months, glass quarterly.

Surface	How we clean it in Dee Why	Typical interval here
Painted concrete	Biocide soft wash, rust remover on fixings, low-pressure rinse	9 to 12 months
Render	Hypochlorite soft wash under 100 psi, rinse under 500 psi	9 to 12 months
Balcony tiles	Soft wash of soffits, tiles cleaned and rinsed to the drain	9 to 12 months
Car park slabs	Hot water, surface cleaner, vacuum recovery	9 to 12 months
Glass	Pure water through carbon-fibre poles, frames and sills scrubbed first	quarterly

These are starting points. On the quote we look at aspect, shade, irrigation and how close the property is to Dee Why Lagoon, then put a recommended cycle in writing. See the full Northern Beaches schedule.

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.
