Need dependable waterproofing in Newtown? Our licensed team provides expert Newtown waterproofing for houses, apartments, townhouses and commercial buildings. We repair leaking bathrooms, brick walls, balconys and more using proven membrane systems, with every job backed by a written 7-year warranty.
Homes and buildings in Newtown – terraces and shop-top flats to apartment blocks – all rely on waterproofing that’s hidden under tiles, screeds and coatings. When it fails, the first sign is usually a stain, a musty smell or a loose tile, and by then water has often been escaping for months.
Because we hold Waterproofing Licence 36763C and certify our work to Australian Standards, our waterproofing is recognised by insurers, certifiers and strata committees – and it’s covered by a written 7-year warranty.
From inside the bathroom to the roof and below ground, we waterproof it all in Newtown. These four services are the ones we’re asked for most often.
Bathrooms
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 Newtown to AS 3740, sealing floor wastes, corners and wall junctions properly.
Damp walls
Salt marks, blistering render and mould low on internal walls all point to water moving through the masonry. We seal external walls and parapets and treat rising damp to stop the problem coming back.
Balconies
Balconies fail at the door sill, the drain and the balustrade fixings. Once water gets past the membrane it stains the ceiling below, lifts tiles and leaves white efflorescence on the soffit. We strip and re-waterproof balconies in Newtown with UV-stable external membranes to AS 4654.
Roofs & decks
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.
Dincel, block and retaining walls, basement slabs and car parks protected against groundwater and soil moisture.
Box and eaves gutters re-membraned so storm water runs off the roof instead of spilling into walls and ceilings.
Positive and negative-side membranes for lift pits that sit below the water table, on new builds or as a remedial fix.
A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
Tile injection stops many shower leaks without ripping out the bathroom, so you avoid weeks of renovation.
Planters and garden beds against walls or over slabs waterproofed and drained so roots and water stay where they belong.
Pool and spa waterproofing that stops water escaping into the surrounding ground, paving and structure.
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.
Every job in Newtown 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.
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.
