Retaining wall cleaning for Killarney Heights homes
Killarney Heights is in the Northern Beaches Council area, about 25 minutes from our base in Elanora Heights. Killarney Heights sits on a ridge above Middle Harbour, with bush on three sides and large homes facing the water views.
Walls near the harbour pick up salt as well as soil salts, and both bloom white on the face. We treat them and rinse them out.
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.
How often in Killarney Heights
For most Killarney Heights homes, retaining wall cleaning is worth doing every 12 to 18 months. Salt and sand build up quickly this close to the water.
What affects the quote in Killarney Heights

Rated 5.0 from 92+ Google reviews.
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.
