Sandstone cleaning and sealing in Matraville

On a Matraville property the sandstone is usually close to the street and in daily use. Front fences and piers face traffic, steps and paths carry family foot traffic, and garden walls hold beds that are watered most days. The marks follow from that: grey film on road-facing stone, a darker track down the centre of steps, green tide-marks along the base of garden walls, and moss in path joints between townhouses. Fine grit from the bay winds settles everywhere. Before quoting, our technicians test the cleaner on a hidden corner of each surface, so the method is confirmed on your stone rather than assumed.

Traffic film comes off with an alkaline detergent made for sandstone and soft brushing, rinsed with warm water at a gentle setting. Algae and moss are dosed with a biocide and left until they have died back, then rinsed and brushed out of joints. Rust rings from furniture are drawn out with a poultice. Garden tide-marks often need both a clean and a change in how beds sit against the wall. We do not use acid, and nothing resembling a turbo nozzle comes near the stone. Every work area has a bund on its downhill side, and the water collected there leaves the site with us.

For a Matraville home, the sealer budget is best spent on the steps, the paths and the tops of the fences: an impregnator that still lets vapour out keeps grit, spilled drinks and muddy garden water from sinking in. That means weekly sweeping and a hose-down every so often are enough to keep it looking right. Walls retaining garden soil stay bare so the damp inside them can get out. We put down natural and enhancing samples for you to compare, then record the product and areas. For townhouse complexes, the strata manager gets the same record. A quick check every couple of years, dripping water on the paths to see whether it beads, tells you when to reseal.
