Salt air, sun and older apartment blocks make Bondi tough on waterproofing. We fix leaking balconies, bathrooms and roofs properly – licensed, with a 7-year warranty.
Bondi NSW 2026
Searching for waterproofing in Bondi? We are experts in providing reliable waterproofing services in Bondi for apartments, terraces and family homes. As licensed Bondi waterproofers, we repair leaking balconies, bathrooms, roofs and damp brickwork with membranes suited to coastal conditions – with a free inspection and a written 7-year warranty.
Bondi is one of Sydney’s densest suburbs. Along Bondi Road and the streets between Bondi Junction and the beach, inter-war and art deco apartment blocks sit beside Federation semis, terraces and newer apartment buildings with balconies chasing ocean views.
Older apartment blocks often have original bathrooms, flat roofs and balconies that were never properly waterproofed, and the salty sea air speeds up the breakdown of membranes, sealants and balustrade fixings. Most of our Bondi work is in strata buildings, where we plan the job around residents and keep the owners’ corporation informed.
Every waterproofing service is available in Bondi. Balconies, bathrooms, flat roofs and brick walls get our closest attention, because that’s where Bondi’s apartment blocks and older homes take the most water.
Coastal apartments
Bondi balconies take salt spray, strong sun and wind-driven rain. Membranes break down, balustrade fixings corrode and water leaks into the apartment below. We strip and re-waterproof balconies with UV-stable membranes and properly sealed edges.
Older units
Many Bondi apartments still have bathrooms from the 1930s to 1970s, built without a modern membrane. When they leak, water travels through the slab to the unit below. We repair leaking showers and waterproof renovated bathrooms to AS 3740.
Flat roofs
Flat concrete roofs on Bondi’s older apartment blocks and roof terraces on newer ones are exposed to full sun and heavy coastal storms. We re-membrane roofs and terraces so the top-floor units stay dry.
Salt & damp
Brick apartment blocks and semis near the beach absorb moisture and salt from the sea air, leading to damp walls, efflorescence and spalling render. We treat and seal external brickwork and parapets to keep water and salt out.
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.
A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.
Remedial floor membranes for wet areas, ground-floor slabs and commercial floors, matched to the substrate so water can't move through.
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.
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.
