Eastwood NSW 2122
Searching for experienced waterproofers in Eastwood? We specialise in waterproofing services in Eastwood 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.
Like much of the northern suburbs, Eastwood is a mix of apartments and shop-top units to established 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.
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.
We offer the full range of waterproofing in Eastwood, with particular focus on balcony, bathroom, basement and rooftop work – the areas where water causes the most damage when membranes fail.
Balconies
Water should run off a balcony, not sit on it. We check falls, outlets and thresholds first, fix any ponding, then apply a flexible external membrane with reinforced corners and properly sealed upstands – so your Eastwood balcony drains properly and stays sealed.
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 Eastwood to AS 3740, sealing floor wastes, corners and wall junctions properly.
Basements
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.
Rooftops
Roof leaks rarely come from the middle of the roof – they start at upstands, outlets, penetrations and junctions with walls. We detail every one of these properly, then apply a roof membrane that can handle Sydney’s heat, UV and heavy downpours.
We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.
Lift pits waterproofed to stop seepage, standing water and corrosion that can damage lift equipment and trigger costly call-outs.
Laundries leak quietly behind machines and tubs. We waterproof the floor and walls properly so the problem doesn't come back.
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.
Planters and garden beds against walls or over slabs waterproofed and drained so roots and water stay where they belong.
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.
Our inspection finds the real source of a leak first, so you only pay to fix what's actually failing.
We hold Waterproofing Licence 36763C and put our name to every membrane we install – no unlicensed subcontractors.
We follow AS 3740 inside and AS 4654 outside, and hand over the paperwork your certifier, insurer or buyer will ask for.
From a single bathroom to a full apartment block or commercial roof, we plan work around residents, tenants and business hours.
Our free quote spells out the problem, the solution and the cost, so you can decide with all the facts.
Every job in Eastwood is backed by a written 7-year warranty. If something isn’t right, we come back and fix it.
We test and trace the leak first, so the quote covers what’s actually failing – not guesswork.
