Leaking showers, balconies and basement car parks repaired across Ashfield NSW 2131 – licensed waterproofers, written quotes and a 7-year warranty on every job.
Ashfield NSW 2131
Searching for a professional waterproofing company in Ashfield? AB Sydney Waterproofing specialises in waterproofing Ashfield homes, apartments and strata buildings. Our licensed team finds the cause of every leak and fixes it with long-lasting membranes, backed by a written 7-year warranty and a free on-site inspection.
Ashfield blends grand Federation homes on wide streets with dense apartment living. Around the station, Liverpool Road and Ashfield Mall, walk-up flats from the 1960s and 70s sit beside newer unit blocks with balconies and underground car parks, while quieter streets near Ashfield Park are full of solid brick houses.
That mix means we see everything – original bathrooms leaking into the unit below, balconies with failed membranes, and basement car parks taking on water. Strata buildings need work planned around residents, and we keep owners’ corporations informed from inspection to final certificate.
We provide every waterproofing service in Ashfield. Bathrooms, balconies, basements and brick walls get our closest attention, because they’re where Ashfield’s houses and unit blocks most often leak.
Units & houses
In Ashfield’s older unit blocks, a failed shower membrane rarely stays your problem alone – water travels through the slab to the ceiling of the unit below. We repair leaking showers and waterproof new bathrooms to AS 3740.
Strata
Balconies on Ashfield’s walk-ups and newer apartment blocks are a common source of leaks into living rooms and car parks. We strip and re-membrane failed balconies, paying close attention to door sills, drains and balustrade fixings.
Car parks
Underground car parks beneath Ashfield apartment buildings let in water through walls, slabs and joints after heavy rain. We seal below-ground walls and slabs and waterproof Dincel and retaining walls on new developments.
Federation homes
Ashfield’s Federation houses and older flats are built from solid brick that can draw in moisture. We treat damp walls, parapets and chimneys so salt, flaking render and mould stop appearing inside.
Flat concrete roofs and roof decks re-membraned so they shed water instead of ponding and leaking into the floor 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.
Pool and spa waterproofing that stops water escaping into the surrounding ground, paving and structure.
