Professional balcony and bathroom waterproofing for homes, units and businesses in Double Bay. Licensed team, written quotes and a 7-year warranty on every job.
Double Bay NSW 2028
Looking for a professional waterproofing service in Double Bay? AB Sydney Waterproofing are experts in providing reliable residential, strata and commercial waterproofing across Double Bay NSW 2028. As licensed waterproofers in Double Bay, 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 eastern suburbs, Double Bay is a mix of luxury apartments and townhouses to large harbourside 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.
We waterproof internal wet areas to AS 3740 and external areas to AS 4654, prepare every surface properly before the membrane goes on, and finish with a compliance certificate where required. That’s how we can back our work with a written 7-year warranty.
Every waterproofing service is available in Double Bay. Balcony, Bathroom, Pool and Basement waterproofing get our closest attention, because they’re the jobs Double Bay property owners call us for most.
Outdoor areas
Leaking balconies are one of the most common strata repairs we do. We re-waterproof balconies and terraces with minimal disruption, keep residents and managers informed, and provide a written warranty for the owners’ corporation records.
Wet areas
Whether you’re renovating or chasing a leak, the membrane under the tiles is what keeps water where it belongs. We install certified wet-area membranes with bond-breakers, reinforced corners and properly sealed penetrations, then issue a compliance certificate for your records.
Pools
Re-tiling an older pool is the best time to waterproof it properly. We prepare and repair the shell, apply a pool-grade membrane and seal fittings and joints before your tiler starts.
Retaining walls
Water pressure behind a wall never stops, so below-ground waterproofing has to be continuous – walls, slab and the joint between them. We seal construction joints and penetrations, then apply a membrane designed for constant moisture.
Concrete roofs, roof gardens and trafficable decks protected with membranes designed for full sun, heat and heavy rain.
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.
Laundry floors, tub areas and wall junctions sealed so constant moisture doesn't damage floors, skirting or the room next door.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
Shower leaking but tiles still solid? Resin injected through the grout lines can seal it in a day, without a full renovation.
Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.
External brick walls, parapets and chimneys treated against damp and salt so moisture stops reaching the inside of the building.
Not sure where the water is coming from? We trace leaks through slabs, walls, showers and balconies before any work is quoted.
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.
A bathroom, balcony or roof above is leaking through the slab.
Efflorescence means water is moving through the masonry.
The bond has failed because the bed underneath is wet.
Water is sitting behind tiles or inside the wall cavity.
More loss than evaporation usually means a failed membrane or joint.
Groundwater is getting past below-ground walls or joints.
Clear, careful and fully certified – our process for every Double Bay property.
We visit your Double Bay property and trace the leak to its source.
A written, itemised quote with no obligation.
Proper preparation first – cracks repaired, corners and joints reinforced – then the membrane goes on.
