The problem

A brick strata with recurring leaks through windows, balconies and gutters, and a facade that needed cleaning, repointing and protection.

How we accessed it

We installed the building’s access systems in 2016 and recertify the anchors, so every repair since has started from a certified, fast rope set-up.

Result

Leaks traced unit by unit and fixed, balconies waterproofed and rebuilt, new gutters and flashings, and the external brick facade cleaned, repointed and sealed in February 2026.
