Retaining wall cleaning for Pymble homes
Pymble is in the Ku-ring-gai Council area, about 30 minutes from our base in Elanora Heights. Pymble's big blocks have big outdoor areas: pools, courts, terraces and long driveways, all under trees. We clean the lot in one visit.
Retaining walls under trees stay damp and grow moss and black mould. We treat the growth before cleaning so it doesn't come straight back.
Feature walls in stone or render on modern homes are cleaned with the care the finish needs, with garden lights and irrigation protected.
How often in Pymble
For most Pymble homes, retaining wall cleaning is worth doing every 12 months. Shade, leaf litter and damp bring growth back sooner.
What affects the quote in Pymble
- Tree canopy: leaf litter and tannin stains often need a separate treatment.
- Older materials: soft brick, original pointing and old paint mean gentler, slower methods.
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.
