Merrylands NSW 2160
Searching for experienced waterproofers in Merrylands? We specialise in waterproofing services in Merrylands for homeowners, landlords, builders and strata managers. From balcony leaks to bathroom and basement repairs, our licensed team gets it right the first time – free inspection, written quote, 7-year warranty.
From apartments around the town centre to family homes and duplexes, the properties we waterproof in Merrylands and across the western Sydney vary a lot. What doesn’t change is our approach: inspect carefully, find the cause, and use a membrane system that suits the surface, the exposure and how the space is used.
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.
From inside the bathroom to the roof and below ground, we waterproof it all in Merrylands. These four services are the ones we’re asked for most often.
Balconies
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
A failed shower membrane lets water into the floor, wall frames and the room or unit below – often for months before you see a stain. We repair leaking showers and waterproof new and renovated bathrooms in Merrylands to AS 3740, sealing floor wastes, corners and wall junctions properly.
Retaining walls
Basements, garages and retaining walls hold back wet soil every day. Without a working membrane and drainage, water pushes through walls, slabs and joints. We waterproof Dincel, block and retaining walls on new builds in Merrylands and repair seepage in existing basements.
Laundry leaks
A laundry needs the same protection as a bathroom. We seal the floor, perimeter upturns and penetrations properly so water from machines, tubs and mopping can’t reach the structure.
Flat concrete roofs and roof decks re-membraned so they shed water instead of ponding and leaking into the floor below.
Box and eaves gutters re-membraned so storm water runs off the roof instead of spilling into walls and ceilings.
Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, matched to the substrate so water can't move through.
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.
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.
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.
Stains and damp patches can be metres from the real leak. We track the water back to where it enters before recommending a fix.
Water damage gets more expensive the longer it runs. If you notice any of these, book a free inspection.
