Most stone sealing enquiries from Killarney Heights start with 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. On the plateau a penetrating sealer on paving and steps keeps moss and clay staining at bay; the drier air means a seal lasts longer, typically five to seven years.

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. We work around Garigal National Park and Bantry Bay, Killarney Heights shops on Starkey Street and the Flat Rock Creek trails, on streets such as Starkey Street, Tralee Avenue, Killarney Drive and Blarney Avenue.

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

Our method in Killarney Heights

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

Sealing happens at least 48 hours after cleaning, once a moisture meter says the stone is dry. Sealer goes on with a low-pressure sprayer, is back-brushed into the surface, and a second coat follows when the product calls for it. Any excess is buffed off so no haze is left.

Breathable products only on sandstone and limestone
Excess removed to avoid haze
Pool and garden protected
Dry weather window confirmed

Highly recommend The Prestige Standard, they cleaned my sandstone, it looks perfect!

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.
