Stone 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.
Near the harbour, a breathable penetrating sealer keeps salt and water out of the stone's pores without trapping moisture.
Heritage stone usually shouldn't be sealed. We'll tell you where sealing helps and where it could do harm.
How often in Castlecrag
For most Castlecrag homes, sealing is worth doing every 3 to 4 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.

Our method
How we handle sealing

Nathan is punctual, knowledgeable, polite and left our place neat and tidy.
Step 01 of 04
Deep clean
The surface is cleaned and any stains treated, as for a full driveway or sandstone clean.

We wait until the stone is dry enough. Porous stone can take a day or more after cleaning.

Great work, fair pricing, and excellent communication.

The chosen sealer goes on evenly by sprayer, roller or brush, then excess is removed.

Excellent service! Nathan is punctual and nothing is a problem.

How often should sealing be done in Castlecrag?
For most homes in Castlecrag, every 3 to 4 years. Homes close to the water need it more often.
Do you offer sealing across Castlecrag?
Yes. Castlecrag is about 40 minutes from our base in Elanora Heights, and we also work in Northbridge and Roseville nearby.
What affects the price of sealing in Castlecrag?
Mostly waterfront; sandstone; heritage materials; steep access. We inspect first and give you a fixed price, itemised by surface.
Do you seal heritage sandstone?
Usually not. Old stone needs to breathe.
Will a sealer change the colour?
A natural-look penetrating sealer leaves the colour almost unchanged. A colour-enhancing sealer deepens it. We'll show you on a test area.
How long before I can walk on it?
Usually a few hours for foot traffic. Driveways need longer before cars go on them, depending on the product.
