Limestone Cleaning and Sealing Sydney: Terraces, Pool Coping and Facades

Q: Can I use an acid wash on limestone?

No. Acid dissolves limestone and leaves a dull, etched surface. We use alkaline and neutral chemistry only.

Q: Why does my limestone go green around the pool?

Shade, moisture and porous stone grow algae quickly. Cleaning plus a sealer slows regrowth significantly.

Q: Can you remove rust from limestone?

Yes, with a non-acidic reducing poultice applied over 24 hours.

Q: Should limestone be sealed?

Yes, especially around pools and barbecue areas. A breathable impregnating sealer keeps water and stains out.

Q: What does limestone cleaning cost?

Every quote is fixed and tailored to the property. We measure the surfaces, confirm the method and send a written price within one business day; call 0494 810 609 or use the quote form and we will come back to you with a figure.

Limestone is calcium carbonate, which means any acid, including many off-the-shelf cleaners, etches it permanently. We clean limestone with alkaline and neutral chemistry, poultices and low pressure.

How we clean it, and how we protect everything around it

No acid under any circumstances

Low pressure only

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.
