Baulkham Hills NSW 2153
Looking for professional waterproofing in Baulkham Hills? AB Sydney Waterproofing provides expert Baulkham Hills waterproofing for family homes, townhouses and commercial buildings. Our licensed team waterproofs pools, retaining walls, bathrooms and balconies with proven systems – with a free inspection and a written 7-year warranty.
Baulkham Hills is classic Hills District living: large brick family homes on sloping blocks, backyard pools, double garages cut into the hillside and plenty of retaining walls holding it all in place. Around Stockland Baulkham Hills and Old Northern Road you’ll also find townhouses and units, with Norwest Business Park just to the north.
Sloping land means water is always moving across and through the ground, putting pressure on retaining walls, garages and lower floors. Many homes are now 20 to 40 years old, so original pools, showers and balconies are due for attention.
We offer every waterproofing service in Baulkham Hills. Pools, retaining walls, bathrooms and balconies get the most attention – the areas where Hills District homes on sloping blocks face the most water.
Backyard pools
Backyard pools are part of life in Baulkham Hills, and many concrete pools built in the 1980s and 90s are now losing water through cracks and failed membranes. We repair and re-waterproof pool shells and waterproof new pools before tiling.
Sloping blocks
On sloping Baulkham Hills blocks, retaining walls and garages cut into the hill hold back wet soil. Without a working membrane and drainage, water seeps into garages, storerooms and lower-level rooms. We waterproof retaining, block and Dincel walls on new and existing homes.
En-suites
Original en-suites and family bathrooms in older Baulkham Hills homes often start leaking into hallways and rooms below. We repair failed shower membranes and waterproof renovated bathrooms to AS 3740.
Two-storey homes
Upstairs balconies over living rooms and tiled alfresco areas are common on Hills homes. When the membrane fails, water stains ceilings and damages tiles. We re-waterproof balconies and outdoor areas so they drain properly.
Flat concrete roofs and roof decks re-membraned so they shed water instead of ponding and leaking into the floor below.
Long box gutters overflow inside when their lining fails. We seal gutters and outlets to keep water on the outside.
Lift pits waterproofed to stop seepage, standing water and corrosion that can damage lift equipment and trigger costly call-outs.
Laundry floors, tub areas and wall junctions sealed so constant moisture doesn't damage floors, skirting or the room next door.
Floor waterproofing for homes, units and businesses, applied with the right primer and system for concrete, screed or timber subfloors.
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.
Before any work is quoted, we pinpoint where the water is coming from – saving you from paying to fix the wrong thing.
