Leaking bathroom, brick wall or balcony? We find the real cause and fix it with the right membrane – licensed, with a free inspection and a 7-year warranty.
Leichhardt NSW 2040
Searching for experienced waterproofers in Leichhardt? We specialise in waterproofing services in Leichhardt for homeowners, landlords, builders and strata managers. From bathroom leaks to brick wall and balcony repairs, our licensed team gets it right the first time – free inspection, written quote, 7-year warranty.
Properties across Leichhardt and the wider inner west range from terraces and Federation homes to apartment blocks. Each brings its own waterproofing challenges – older wet areas built before modern membranes were required, outdoor areas exposed to sun and storms, and below-ground walls that hold back wet soil.
Our process is simple: a free inspection, a clear written quote, proper surface preparation, the right membrane applied at full thickness, and testing and certification at the end. No shortcuts, and no paying twice for the same leak.
We offer the full range of waterproofing in Leichhardt, with particular focus on bathroom, brick wall, balcony and laundry work – the areas where water causes the most damage when membranes fail.
Showers & en-suites
Showers leak when the membrane is cracked, missing at the hob or wall junction, or wasn’t sealed around the floor waste. In Leichhardt we test, trace and repair the actual failure point – then re-waterproof to AS 3740 so the repair lasts as long as the tiles.
Brickwork
Solid brick walls can draw moisture up from the ground or let rain through, causing flaking paint, salt deposits and musty rooms. We treat and seal brick walls, parapets and chimneys in Leichhardt so moisture stays out of the masonry.
Outdoor areas
A balcony over a living room or garage needs a membrane that handles full sun, heavy rain and movement. We prepare the slab properly, correct falls where needed, and detail every edge, outlet and threshold so water drains away instead of finding its way inside.
Wet areas
Most laundry leaks come from the junction between floor and wall, where water from machines and tubs sits and soaks in. We waterproof the floor and turn the membrane up the walls so water stays contained.
Remedial roof membranes for homes, apartments and commercial buildings, built to handle UV, heat and heavy downpours.
Below-ground waterproofing for new builds and remedial seepage repairs in existing basements and garages.
We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.
Positive and negative-side membranes for lift pits that sit below the water table, on new builds or as a remedial fix.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
Tile injection stops many shower leaks without ripping out the bathroom, so you avoid weeks of renovation.
Planter boxes and podium gardens lined with root-resistant membranes and proper drainage so they don't leak into walls or car parks.
Pool and spa waterproofing that stops water escaping into the surrounding ground, paving and structure.
Not sure where the water is coming from? We trace leaks through slabs, walls, showers and balconies before any work is quoted.
Every Leichhardt job is done under Waterproofing Licence 36763C, so the work is recognised by insurers, certifiers and strata committees.
We work for homeowners, landlords, builders, strata managers and businesses across Leichhardt and nearby suburbs.
A free written quote that explains what’s wrong, the system we’ll use and the price – no surprises when the job is done.
Our waterproofing comes with a 7-year written warranty – long after the tiles go down, we still stand behind the work.
Water rarely shows up where it gets in. A free inspection traces the leak to its source before we quote, so you pay to fix it once.
Wet areas are waterproofed to AS 3740 and outdoor areas to AS 4654, and you receive a compliance certificate when we finish.
