Exterior cleaning in Killarney Heights

A 1960s to 1970s suburb of brick family homes on large sloping blocks that back onto Garigal National Park and Bantry Bay, many extended or rebuilt with render, pools and decks taking the bush outlook. Most of what we clean here dates from 1960s to 1970s with 2010s rebuilds, on sandstone ridge above Bantry Bay with bush gullies on three sides.

We work around Garigal National Park and Bantry Bay, Killarney Heights shops on Starkey Street, the Flat Rock Creek trails and Killarney Heights Oval, on streets such as Starkey Street, Tralee Avenue, Killarney Drive, Blarney Avenue and Dublin Street. The defining exterior problem is leaf-choked gutters and valleys on the park-edge homes, moss on shaded paths and driveways, and black mould on render and painted brick under the canopy.

Terrey Hills, Duffys Forest, Belrose, Davidson, Frenchs Forest, Ingleside and the plateaus behind the beaches back onto Garigal and Ku-ring-gai Chase national parks. Salt is minor; leaf litter, shade, bushfire-prone-land obligations and acreage-scale hard surfaces decide the work.

Field note from Killarney Heights. Killarney Heights' park-edge streets like Tralee Avenue lose the afternoon sun to the ridge; the rendered rebuilds there grow mould on the west wall as well as the south, so we quote four elevations where elsewhere we would quote two. Nathan G, Founder

Planning and site constraints we check in Killarney Heights:

• Bushfire-prone land along the Garigal and Bantry Bay edges
• Middle Harbour catchment via Bantry Bay

Run-off. Anything washed off a Killarney Heights property ends up in Middle Harbour via Bantry Bay 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.
