Professional balcony and bathroom waterproofing for homes, units and businesses in Darlinghurst. Licensed team, written quotes and a 7-year warranty on every job.
Darlinghurst NSW 2010
Need dependable waterproofing in Darlinghurst? Our licensed team provides expert Darlinghurst waterproofing for houses, apartments, townhouses and commercial buildings. We repair leaking balconys, bathrooms, rooftops and more using proven membrane systems, with every job backed by a written 7-year warranty.
Like much of the inner city, Darlinghurst is a mix of terraces and converted warehouses to apartment blocks and shopfronts. 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.
Our process is simple: a free inspection, a clear written quote, proper surface preparation, the right membrane applied at full thickness, and testing and certification at the end. No shortcuts, and no paying twice for the same leak.
Every waterproofing service is available in Darlinghurst. Balcony, Bathroom, Rooftop and Brick Wall waterproofing get our closest attention, because they’re the jobs Darlinghurst property owners call us for most.
Outdoor areas
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 Darlinghurst balcony drains properly and stays sealed.
Bathrooms
Showers leak when the membrane is cracked, missing at the hob or wall junction, or wasn’t sealed around the floor waste. In Darlinghurst we test, trace and repair the actual failure point – then re-waterproof to AS 3740 so the repair lasts as long as the tiles.
Roofs & decks
From apartment rooftops to commercial roof decks and roof gardens, we install trafficable and non-trafficable membranes to suit how the roof is used, with box gutters and outlets sealed as part of the job.
Damp walls
Damp brickwork is usually a sign of failed or missing damp-proofing, porous bricks or poor drainage at the base of the wall. We identify the cause first, then apply treatments and sealers suited to the age and type of brick.
Groundwater kept out of basements, garages and below-ground rooms with membranes suited to constant moisture pressure.
We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.
Positive and negative-side membranes for lift pits that sit below the water table, on new builds or as a remedial fix.
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.
Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.
Concrete pools and spas waterproofed so the shell holds water and the paving and ground around it stay dry.
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 Darlinghurst 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.

Most balcony leaks start at the door sill, the drain or the balustrade fixings, where the membrane has cracked or was never properly detailed. We find the failure point and re-waterproof the balcony properly.
Often, yes. If the tiles are still well bonded, tile injection seals the leak from underneath without demolition. If the membrane has failed completely, we’ll explain why a strip-out is the better long-term fix.
Yes. Wet-area waterproofing comes with a compliance certificate to AS 3740, and every job is covered by our written 7-year warranty.
It depends on the size of the area, how much damage the leak has caused and the membrane system needed. Every job starts with a free inspection and a written, itemised quote, so you know the exact price before work begins.
