Travertine cleaning and sealing in Balgowlah Heights

Travertine in Balgowlah Heights tends to sit at the top of the garden: the main terrace off the living areas, pool decks oriented toward the view, and outdoor kitchens. These areas take the wind off the harbour, so fine salt and grit settle on the stone, and pool water dries into scale along the coping. Properties near Dobroyd Head and the reserves get leaf and flower litter blown across the paving, which leaves tannin marks if it sits wet. Because travertine is a limestone, those marks have to be handled with limestone-safe chemistry, not the acidic tile cleaners sold for pool areas.

We clean with alkaline and pH-neutral products and soft rotary brushes that work into the holes, followed by a low-pressure rinse. A cover or barrier keeps the pool clean, and rinse water is vacuumed up instead of spilling over the terrace edge. If leaf stains have penetrated, a targeted poultice draws them out. During the clean, our technicians note where filler has washed out of holes, where traffic paths have worn the finish and whether any dull patches are etching. You get a clear picture of what the clean has resolved and what would need filling or honing.

After the clean, and once the deck has dried, open holes are filled in a matching tone and an impregnator suited to wind-blown salt and pool water is worked in. It sits inside the stone, so the deck keeps its natural grip. An enhancing sealer is available if you would like the colour deepened, tested first on your own stone. Wind-exposed decks lose protection faster than sheltered ones, so plan on testing the coping and the most exposed edge of the terrace with a few drops of water every year, and re-seal those areas once drops darken the stone.
