Schofields NSW 2762
Looking for a professional waterproofing service in Schofields? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Schofields NSW 2762. As licensed waterproofers in Schofields, 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.
Like much of the north-west Sydney, Schofields is a mix of new housing estates and family homes. Whatever the building, water finds the weakest point – a cracked grout line, a failed door sill, a blocked outlet or an unsealed joint – and the damage often shows up a long way from where the water gets in.
Every job starts with finding out exactly where the water is coming from. We then recommend the simplest fix that will last – whether that’s tile injection, a remedial membrane or a full strip-out – and explain the options clearly before you decide.
Every waterproofing service is available in Schofields. Basement, Bathroom, Balcony and Laundry waterproofing get our closest attention, because they’re the jobs Schofields property owners call us for most.
Basements
Damp patches, salt and moss on a retaining wall, or water across a garage floor after rain, mean water is getting through instead of draining away. We find the entry points and seal walls, slabs, joints and lift pits properly.
Bathrooms
Most bathroom leaks start at the same few weak points: cracked grout, a poorly sealed floor waste, or a membrane that stops short at the wall. We find exactly where water is escaping and fix it – with tile injection when the tiles are sound, or a new membrane when they’re not.
Terraces
Balconies fail at the door sill, the drain and the balustrade fixings. Once water gets past the membrane it stains the ceiling below, lifts tiles and leaves white efflorescence on the soffit. We strip and re-waterproof balconies in Schofields with UV-stable external membranes to AS 4654.
Wet areas
Many older laundries were built with no membrane at all, especially in extensions and converted spaces. We waterproof the floor and wall junctions to AS 3740 during renovations, or as a stand-alone repair.
Remedial roof membranes for homes, apartments and commercial buildings, built to handle UV, heat and heavy downpours.
Long box gutters overflow inside when their lining fails. We seal gutters and outlets to keep water on the outside.
Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.
Floor waterproofing for homes, units and businesses, applied with the right primer and system for concrete, screed or timber subfloors.
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.
Damp brickwork lets water track inside. We treat and seal masonry walls to keep moisture out for good.
Membranes for concrete pools and spas, applied before tiling on new pools or as a remedial fix for a pool that's losing water.
Before any work is quoted, we pinpoint where the water is coming from – saving you from paying to fix the wrong thing.
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.
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.
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.
These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.
Groundwater is getting past below-ground walls or joints.
Water is passing through the wall instead of draining behind it.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
A bathroom, balcony or roof above is leaking through the slab.
Efflorescence means water is moving through the masonry.
