Looking for expert bathroom waterproofing in Concord? AB Sydney Waterproofing provides licensed waterproofing services in Concord for character homes, renovations and unit blocks. Our team waterproofs bathrooms, balconies, brick walls and pools with systems suited to older homes – free inspection and a written 7-year warranty.
Concord is a leafy suburb on the Parramatta River, with Majors Bay Road at its centre and parks and foreshore walks along the water. Its streets are full of Federation and inter-war brick homes and Californian bungalows, many renovated and extended, alongside newer homes and small unit blocks.
Renovations are where waterproofing matters most in Concord. Original bathrooms rarely had a membrane, rear extensions add new wet areas and balconies, and solid brick walls can draw in moisture. We make sure every new wet area is certified and every old problem is fixed at the source.
Every waterproofing service is available in Concord. Bathrooms, balconies, brick walls and pools get our closest attention – the areas Concord’s character homes and renovations depend on most.
Renovations
Concord renovations often uncover original bathrooms with no membrane or one that failed long ago, with water damage to timber floors underneath. We waterproof new bathrooms to AS 3740 before your tiler starts and repair leaking showers in existing bathrooms.
Extensions
Second-storey additions and rear extensions in Concord often include balconies and terraces above new living areas. We waterproof them properly from the start, and re-waterproof older balconies that leak into rooms below.
Character homes
Federation and inter-war brick homes can suffer rising and penetrating damp, which shows as flaking paint, salt and musty rooms. We treat and seal brick walls, parapets and chimneys with systems suited to older masonry.
Backyard pools
Many Concord homes have pools that are decades old. If yours is losing water, we’ll find the leak, repair cracks and joints and re-waterproof the shell. We also waterproof new pools in renovations.
Flat concrete roofs and roof decks re-membraned so they shed water instead of ponding and leaking into the floor below.
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.
Laundries leak quietly behind machines and tubs. We waterproof the floor and walls properly so the problem doesn't come back.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
Epoxy resin injected under existing tiles seals a leaking shower without demolition – a faster, lower-cost fix when the tiles are still sound.
Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.
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.
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.
You’ll know the scope and price in writing before we start. The price we quote is the price you pay for that scope.
