Soft Washing & House Washing Newcastle & Lake Macquarie

Professional soft washing and house washing throughout Newcastle and Lake Macquarie. We safely remove mould, mildew, algae and built-up grime using specialised low-pressure systems designed to protect your home’s exterior.

Safe & Effective Exterior Cleaning for Coastal Conditions

Properties across Newcastle and Lake Macquarie are constantly exposed to moisture, salt air and humidity. These conditions accelerate mould growth, staining and organic build-up on exterior surfaces.

Our soft washing method treats contamination at the source, breaking down organic growth and restoring surfaces without the risk of high-pressure damage. The result is a cleaner, fresher exterior that stays looking better for longer.

Soft Washing FAQs

What is soft washing?

Soft washing is a low-pressure exterior cleaning method used to remove mould, algae and grime from surfaces like render, brick and weatherboard. A specialised cleaning solution is applied, allowed time to dwell and break down organic growth, then gently rinsed off using medium-to-low pressure.

For house washing — yes. Soft washing treats mould at the source and is much safer for paint and delicate surfaces than high-pressure cleaning.

Yes. We adjust pressure levels and use professional-grade solutions designed specifically for exterior surfaces.

Yes. We take precautions to protect surrounding landscaping and recommend keeping pets inside during the service.

Typically 12–24 months depending on moisture, shade and surrounding conditions.
