Marrickville NSW 2204
Looking for a professional waterproofing service in Marrickville? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Marrickville NSW 2204. As licensed waterproofers in Marrickville, we find the real cause of every leak and fix it with long-lasting membranes – backed by a free inspection and a written 7-year warranty.
Properties across Marrickville and the wider inner west range from terraces and Federation cottages to warehouses and apartments. 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.
Because we hold Waterproofing Licence 36763C and certify our work to Australian Standards, our waterproofing is recognised by insurers, certifiers and strata committees – and it’s covered by a written 7-year warranty.
Every waterproofing service is available in Marrickville. Bathroom, Brick Wall, Rooftop and Balcony waterproofing get our closest attention, because they’re the jobs Marrickville property owners call us for most.
Wet areas
Showers leak when the membrane is cracked, missing at the hob or wall junction, or wasn’t sealed around the floor waste. In Marrickville 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 Marrickville so moisture stays out of the masonry.
Rooftops
A roof membrane only works if every upstand, outlet and penetration is sealed. We prepare the surface, reinforce joints and corners, and apply a UV-stable system matched to how the roof is used – plant deck, terrace or non-trafficable roof.
Balconies
Water should run off a balcony, not sit on it. We check falls, outlets and thresholds first, fix any ponding, then apply a flexible external membrane with reinforced corners and properly sealed upstands – so your Marrickville balcony drains properly and stays sealed.
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.
Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.
A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.
Floor waterproofing for homes, units and businesses, applied with the right primer and system for concrete, screed or timber subfloors.
Shower leaking but tiles still solid? Resin injected through the grout lines can seal it in a day, without a full 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.
Our inspection finds the real source of a leak first, so you only pay to fix what's actually failing.
All work is carried out under Waterproofing Licence 36763C. Ask to see it on site – a licensed contractor protects you, your insurer and your strata.
You’ll know the scope and price in writing before we start. The price we quote is the price you pay for that scope.
You get a written 7-year warranty on our workmanship, so you can renovate, rent or sell with confidence.
Stains and damp patches can be metres from the real leak. We track the water back to where it enters before recommending a fix.
Internal wet areas to AS 3740 and external membranes to AS 4654, with a compliance certificate for your records, sale or strata.
One leaking shower or a whole building – we scale the team and schedule to suit, with minimal disruption.
Water damage gets more expensive the longer it runs. If you notice any of these, book a free inspection.
The bond has failed because the bed underneath is wet.

Rising or penetrating damp is getting into the masonry.
Efflorescence means water is moving through the masonry.
