Exterior mould removal for Castlecrag homes
Castlecrag is in the Willoughby City Council area, about 40 minutes from our base in Elanora Heights. Natural rock, bush and shade make this one of the most sensitive places we work.
Salt air and damp near the harbour feed black mould on shaded walls.
Mould on old render and timber is treated at low pressure so the surface isn't damaged.
How often in Castlecrag
For most Castlecrag homes, mould removal is worth doing every 12 months on shaded walls. 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.
- Heritage materials: test patches and lower pressure take longer than a modern build.
- Bush debris: gutters and roofs may need clearing before washing.
- Steep access: carrying gear down stairs and running long hoses adds time.
Every quote is fixed and itemised by surface after a quick inspection.

Nathan did a great job washing the external sides of our house. The weatherboard was dirty and had cobwebs. Nathan went above and beyond our expectations, the house was perfectly clean and all the cobwebs were gone.
Nathan did an incredible job at my home cleaning all my outdoor paving areas. He even washed some extra areas of my house free of charge and his price was very reasonable. He's a lovely fella and was prompt, friendly and professional. I highly recommend Nathan's services.
Nathan just completed a pressure wash of our travertine pavers under our alfresco area, around the pool and the sundeck. What an absolutely fantastic job. Nathan is punctual, knowledgeable, polite and left our place neat and tidy. We will certainly be calling him back on a regular basis and can highly recommend him.
