Limestone sealing for Castlecrag homes
Castlecrag is in the Willoughby City Council area, about 40 minutes from our base in Elanora Heights. Castlecrag was designed by Walter Burley Griffin and Marion Mahony Griffin to sit within the sandstone and bush above Middle Harbour.
Limestone near the harbour soaks up salt that crystallises as it dries and can break down the face over time. A breathable sealer slows it down.
Old limestone and block walls are sealed with a breathable product made for soft masonry, after a gentle test.
How often in Castlecrag
For most Castlecrag homes, limestone sealing is worth doing every 2 to 3 years. Salt and sand build up quickly this close to the water.
What affects the quote in Castlecrag
- Waterfront: wash water near the shoreline may need to be contained and collected.
- Sandstone: low pressure and dwell time for the cleaner take longer than hard paving.
- Heritage materials: test patches and lower pressure take longer than a modern build.
- Steep access: carrying gear down stairs and running long hoses adds time.
Every quote is fixed and itemised by surface after a quick inspection.
