Why it Matters
Balcony leaks are one of the most destructive water problems in a home.
Water finding its way through a failed balcony membrane does not just stay on the surface. It works into the structural slab, internal ceilings, and wall framing below. By the time you see water stains or bubbling paint downstairs, the damage has usually been building for months.
We see it constantly. A homeowner notices a damp patch in the ceiling below their balcony and calls us in. We open it up and find the membrane has failed across most of the surface, not just in one spot. What looked like a minor leak turns into a much bigger job than it needed to be.
The earlier you act, the smaller the job. We will give you a straight assessment of what is going on — and a fixed price to sort it out.

Sound Familiar?
Tired of the runaround?
We hear the same stories from homeowners all the time. And we built BayFix to fix every one of them.
Surface patches that buy six months, not a fix
A sealant coating on a failed membrane will hold for a season, then fail again. We inspect the full waterproofing system before we quote, so the repair actually solves the problem.
Damage you cannot see yet
Visible water stains are the end result, not the start. By the time you see them downstairs, there is usually hidden damage in the ceiling or framing that needs to be factored into the scope.
Strata and insurance complications
Balcony leaks in apartments often involve strata managers, owners corporations, or insurance assessors. We work with all of them regularly and can provide the documentation they need.
Vague quotes that blow out
Estimates without a proper inspection behind them are guesses. We assess the full scope before we quote you a fixed price. What we quote is what you pay.

FAQs
Questions people usually ask
Common signs are water stains or damp patches on ceilings below the balcony, bubbling or lifting surface finishes, efflorescence on the slab edge, or a musty smell in rooms underneath. If you are seeing any of these, the membrane has likely been compromised for a while. We will do a proper inspection and tell you exactly what we find.
Yes. We work with strata managers, owners corporations, and individual lot owners regularly. We can provide scope of works documentation, compliance certificates, and any other paperwork required by the owners corporation or insurer.
Yes. All our waterproofing work is carried out to AS 3740 standards and we provide compliance certificates on completion. This is important if you are dealing with strata, insurance, or are planning to sell the property.
It depends on the balcony height and access. For ground level or easily accessible balconies, no. For upper floor balconies where safe access requires it, yes — and we factor that into the quote upfront so there are no surprises.
A repair targets a localised failure — a cracked joint, a failed section of membrane — where the rest of the waterproofing system is still intact. A rebuild is needed when the membrane has failed across the full surface or there is structural damage to the slab. We will tell you which it is after the inspection, before you commit to anything.
We are based in Hobsons Bay and work across the surrounding western and inner suburbs — Williamstown, Altona, Newport, Spotswood, Footscray, Yarraville and more. Not sure if you are in our zone? Give us a call and we will let you know.
