Northern Beaches
Exterior mould removal on the Northern Beaches
Mould is one of the most common problems on Northern Beaches homes. South-facing walls, shaded paths and homes near the lagoons and bush stay damp for months. We treat the growth at the root, so it doesn't come back within weeks.
Sydney's humidity and shady gardens grow mould on anything that stays damp: south-facing walls, side passages, timber, stairs under trees. Rinsing it off with high pressure removes what you see but leaves the roots, and it's back within months.
We treat mould with a solution that kills it, give it time to work, then rinse. Slippery green paths and stairs are made safe again, and we point out the damp sources that keep feeding the growth.

What affects the quote
- Bush debris: gutters and roofs may need clearing before washing.
- Leaf litter: tannin stains and moss need treating, not just washing.
- Steep access: carrying gear down stairs and running long hoses adds time.

What our clients say

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.

Still have a question?
Talk to Nathan directly. He quotes and attends every job himself.
Do you offer mould removal everywhere on the Northern Beaches?
Yes. We cover all 42 suburbs listed above from our base in Elanora Heights.
Will the mould come back?
Eventually, if the area stays damp and shaded. Treatment slows it a lot.
Is the treatment safe for pets?
Keep pets away until surfaces are rinsed and dry.
Can you remove mould from timber?
Yes, at low pressure with a timber-safe treatment.
Why are my stairs so slippery?
Algae. Treating it makes them safe again.
Do you treat roofs for moss?
Yes. Every roof we do is a moss, mould and lichen treatment, and it kills the growth off over about 12 months.
