Why this decision matters more for premium homes
A budget exterior washing service using incorrect pressure or chemical settings on the wrong surface can damage paint coatings, force water into cladding joints, or strip protective treatments from roofing materials. For high-value homes with premium cladding systems, bespoke joinery or carefully maintained paintwork, the wrong approach can cause damage worth tens of thousands of dollars to repair.
The right provider understands the differences between surface types, knows when to use soft washing versus pressure washing, and selects chemicals appropriate to the specific situation, not just the cheapest option available.
What to look for
Insurance
Public liability insurance is essential. Ask for confirmation before booking.
Experience with high-value properties
Ask specifically whether they have experience with your cladding type and property value range.
Appropriate technique
Do they default to soft washing for sensitive surfaces, or do they use one method for everything?
Product transparency
Are they able to tell you exactly what products they use and confirm they are appropriate for your surfaces?
Environmental practices
How do they manage runoff? Are their products safe for gardens, waterways and tank water systems?
References and reviews
Credible Google Reviews from identifiable residential clients are a reasonable indicator of service quality.
Clear pricing
A reputable provider can provide a clear quote after understanding your property, not just a vague range.
Communication quality
How they communicate before the job is usually a good indicator of how they'll communicate during and after.
