Torch-on waterproofing, locally
Waterproofing Hills District
Big family homes with rooftop alfresco areas, balconies over garages and planter boxes framing the entry. The Hills builds generously, and generous builds have more edges to keep dry.
Waterproofing in Hills District
From Castle Hill and Baulkham Hills to Kellyville, Bella Vista and Rouse Hill, the Hills District's housing stock runs large: double-storey homes with balconies over living spaces, alfresco terraces above garages, home theatres under decks, and landscaping with built-in planters against the house. Every one of those is a waterproofing detail, and in a district this new, most failures trace back to install-day shortcuts, not age.
The balcony-over-garage is the Hills' most common call-out. Builders' original liquid membranes, applied thin and never flood-tested, give up inside a decade, and the first sign is a stain on the garage ceiling or a rusting door frame below. We strip these back, torch on a proper two-layer system, flood test, and retile, permanently ending a leak the home was effectively born with.
We also waterproof new builds and renovations across the district, working in sequence with builders and landscapers so decks, planters and terraces get membrane done right the first time, with a warranty the homeowner holds for decades.
Whatever the building, the process is the same: an inspection with photos, a fixed itemised quote, two-layer torch-on installed to manufacturer spec, flood testing where it counts, and a warranty in writing. Not sure what you're looking at? Our guides on waterproofing costs and choosing a contractor are a good place to start.

What Hills District calls us about
Balcony & podium waterproofing
Leaking balconies are Sydney's most common waterproofing failure, and the most expensive to ignore.
See the work 02Planter box waterproofing
A planter box is a rooftop garden bed with your ceiling underneath it: permanently wet soil, roots hunting for weaknesses, and fertiliser eating cheap membranes.
See the work 03Roof waterproofing
Leaking roof? We find the fault, fix the cause and membrane the roof so it never does it again.

The toughest waterproofing system there is, applied with an open flame by two blokes with forty years on the torch.

Asked locally
Our balcony is only eight years old. Why is it leaking already?
Because age isn't what kills most balconies, installation is. A membrane applied too thin, undetailed thresholds and posts, no flood test: the balcony was leaking slowly from year one and took eight years to show. The rebuild, done to spec, is the last time you'll think about it.
Can't afford for it to leak twice?
Call the blokes whose names are on the patch. Straight answers, a fixed quote and a warranty that means something.
