Chester Hill NSW 2162
Looking for a trusted waterproofing service in Chester Hill? We are experts in providing reliable Chester Hill waterproofing for family homes, granny flats and small unit blocks. Our licensed team repairs leaking bathrooms, laundries, showers and damp brick walls – with a free inspection and a written 7-year warranty.
Chester Hill is a quiet residential suburb in Sydney’s south-west, centred on the shops around the station and Waldron Road. Many of its homes are post-war brick and fibro houses, extended over the years with rear additions, along with newer duplexes and granny flats on subdivided blocks.
Rear additions often mean bathrooms and laundries built at different times with different standards, and older houses can suffer from damp brickwork. Owners usually want leaks fixed without a full renovation – so we start with an honest inspection and recommend the simplest repair that will last.
We offer every waterproofing service in Chester Hill. Bathrooms, laundries, tile injection repairs and brick walls get the most attention, because that’s where the suburb’s homes most often need help.
Older homes
Original bathrooms in Chester Hill’s older homes often leak through failed or missing membranes, damaging floors and walls. We waterproof new and renovated bathrooms to AS 3740 and repair leaking showers before the damage spreads.
Rear additions
Laundries in Chester Hill are often in rear additions or converted spaces, sometimes with no membrane at all. We waterproof laundry floors, tub areas and wall junctions so leaks from machines and tubs don’t damage the house.
No demolition
If your shower tiles are still firmly bonded, tile injection can seal the leak in a day without removing them. Epoxy resin is injected through the grout lines to block the gaps where water escapes.
Damp walls
Older brick homes can draw moisture up from the ground or let rain through the walls, leading to peeling paint, salt marks and musty rooms. We treat and seal the brickwork to stop damp coming back.
Balconies, terraces and courtyards re-membraned at door sills, drains and balustrades so water stops reaching rooms and ceilings below.
Remedial roof membranes for homes, apartments and commercial buildings, built to handle UV, heat and heavy downpours.
Groundwater kept out of basements, garages and below-ground rooms with membranes suited to constant moisture pressure.
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.
Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.
Planter boxes and podium gardens lined with root-resistant membranes and proper drainage so they don't leak into walls or car parks.
Pool and spa waterproofing that stops water escaping into the surrounding ground, paving and structure.
