Licensed waterproofing for Blacktown’s homes, duplexes and apartment blocks – leaking showers, balconies and basements fixed properly, with a 7-year warranty.
Blacktown NSW 2148
Looking for reliable waterproofers in Blacktown? AB Sydney Waterproofing delivers professional waterproofing in Blacktown for houses, duplexes, apartments and commercial buildings. Our licensed team fixes leaking showers, balconies, basements and roofs with quality membrane systems, and backs every job with a written 7-year warranty.
Blacktown is one of western Sydney’s biggest centres. Around the station, Main Street and Westpoint, apartment buildings and mixed-use developments have replaced older shops, while the surrounding streets mix post-war brick and fibro homes with newer duplexes, townhouses and granny flats.
That mix keeps us busy. Older homes need bathrooms and laundries brought up to modern standards, new duplexes need certified wet-area membranes, and apartment buildings need balconies and basement car parks that stay dry. We inspect first and recommend the right fix for each building.
All our waterproofing services are available in Blacktown. Bathrooms, balconies, basements and roofs get the most attention – where Blacktown’s homes, apartments and commercial buildings most often leak.
Homes & duplexes
Leaking showers are the most common call we get from Blacktown – in older homes with original bathrooms and in new duplexes and granny flats. We waterproof new bathrooms to AS 3740 and repair failed membranes before water damages floors and walls.
Apartments
Apartment buildings around Blacktown station and Main Street have balconies stacked above living areas and shops. When membranes fail at door sills and drains, the leak shows up downstairs. We re-waterproof balconies properly and work with strata.
Basements
Newer apartment and mixed-use buildings in Blacktown sit over basement car parks, and homes on sloping blocks rely on retaining walls. We waterproof Dincel and retaining walls on new builds and repair seepage in existing basements.
Commercial
Shops, offices and light-industrial buildings around Blacktown often have flat concrete roofs and box gutters that pond and leak in storms. We re-membrane roofs and gutters to protect tenants, stock and equipment below.
Long box gutters overflow inside when their lining fails. We seal gutters and outlets to keep water on the outside.
Lift pits waterproofed to stop seepage, standing water and corrosion that can damage lift equipment and trigger costly call-outs.
Laundry floors, tub areas and wall junctions sealed so constant moisture doesn't damage floors, skirting or the room next door.
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.
Damp brickwork lets water track inside. We treat and seal masonry walls to keep moisture out for good.
Concrete pools and spas waterproofed so the shell holds water and the paving and ground around it stay dry.
Not sure where the water is coming from? We trace leaks through slabs, walls, showers and balconies before any work is quoted.
Every Blacktown 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 Blacktown 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.
These are the warning signs we see most in Blacktown homes, units and commercial buildings. Get them checked early to avoid bigger repairs.
The bond has failed because the bed underneath is wet.
A bathroom, balcony or roof above is leaking through the slab.
Water is sitting behind tiles or inside the wall cavity.
Groundwater is getting past below-ground walls or joints.
Box gutters or roof outlets can’t cope and spill inside.
Water is wicking out of a wet area into the timber next to it.
The same clear four steps on every Blacktown job – house, duplex, apartment or commercial site.
We visit your Blacktown property and trace the leak to its source.
You get the findings, the fix and the cost in writing.
We clean, repair and prime the substrate, then build up the membrane to the specified thickness.
Wet areas are flood tested where suitable, then certified and covered by our warranty.
We work right across Blacktown – the apartments and shops around the station, Main Street and Westpoint, the residential streets on both sides of the railway, and the commercial and light-industrial areas nearby. Our team works across western Sydney every week.
