Waterproofing Inner West
Terrace parapets, box gutters and hundred-year-old roofs meeting modern membranes. The Inner West is heritage detail work, and heritage detail work is where hand skills show.
Waterproofing in Inner West
Newtown, Marrickville, Leichhardt, Balmain, Ashfield, Dulwich Hill: the Inner West runs on building stock that predates every membrane on the market. Terrace houses with parapet walls and box gutters, warehouse conversions with big flat roofs, and older strata blocks whose balconies have outlived two or three waterproofing generations.
Parapets and box gutters are the Inner West's signature leaks. A parapet takes weather from both faces and moves with the building, and a box gutter is a river running through the middle of your roof. Both fail exactly where sealant-and-hope repairs go to die. We membrane them properly: torch-welded bitumen turned through the details, capped and terminated so the whole assembly sheds water as one system. The photo above this page is our work on exactly that kind of roof.
For warehouse conversions and strata buildings we handle full roof re-membranes, balcony strip-backs and remedial diagnosis, with straight advice about what's worth repairing and what's earned a replacement.
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 Inner West calls us about
Roof waterproofing
Leaking roof? We find the fault, fix the cause and membrane the roof so it never does it again.

Someone waterproofed it once and it failed.
See the work 03Balcony & podium waterproofing
Leaking balconies are Sydney's most common waterproofing failure, and the most expensive to ignore.

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

Asked locally
Can you waterproof heritage terraces without changing how they look?
Yes. Membrane work on parapets and box gutters sits within the roof line, and mineral cap sheets come in finishes that read correctly on older buildings. From the street, the terrace looks untouched. From the ceiling inside, it finally stays dry.
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.
