Why this matters for Melbourne properties

This Pressure Cleaning article is written for Melbourne owners and managers who need more than a quick blast. Pressure Cleaning jobs in our city require a surface diagnosis before any cleaning starts.

In Melbourne, everything from growth corridor new-build mortar smear to inner-suburb heritage brick has its own cleaning risk profile. The right method, chemistry and pressure keep the surface safe and the result lasting.

Identify the wall surface

Painted brick, rendered block and timber all require different chemicals and pressure settings.

Use biocide before pressure

A dwell period with the right biocide kills organisms and reduces the need for aggressive mechanical force.

Rinse gently and monitor

A final low-pressure rinse removes residue and limits the risk of washing fresh coatings off the surface.
