Exterior Cleaning in the Northern Beaches

Salt, sand and steep streets across the Northern Beaches

Manly sits on the isthmus between the ocean and the harbour, so salt reaches it from both sides and no elevation is sheltered. Very few Sydney suburbs are as exposed. In Dee Why the land climbs steeply from the beach toward the headland and Cromer, and the higher a roof sits, the harder onshore wind drives salt into tile joints and sheet profiles. Salt stays faintly damp, binds windblown sand and dust to whatever it lands on and holds moisture there.

Housing and trees decide the rest. Dee Why’s 1960s and 1970s walk-up blocks often carry low-pitch metal deck roofs and box gutters behind parapets, where a blocked outlet ponds water above a top-floor unit. Manly mixes art deco walk-ups with Federation and interwar semis carrying original terracotta and painted timber, much of it in heritage conservation areas on narrow, steep streets. Norfolk Island pines along both beachfronts shed fine needles almost year round, and they pack with sand into gutters and lodge along solar panel frames.

It shows on every surface: a grey salt film on render and ocean-facing glass, mould on balcony soffits and shaded southern walls, algae on shaded stairs and basement ramps, droppings from gulls and lagoon birds on solar arrays, and beach sand ground into concrete and paving. So we vacuum gutters from the ground, soft wash walls at low pressure, keep pressure low on sandstone, and rinse with fresh or purified water so the salt actually leaves.
