Two problems, done properly
Showers and balconies fail for the same reason — the waterproofing underneath has gone, not the tiles on top. That is why lifting the tiles is usually the wrong answer.
Leaking Shower Repairs
Stains on the ceiling below, mould that keeps coming back, a musty smell you cannot place. We find where the water is actually getting in and seal it — through the existing tiles in most cases.
- No tile removal on most jobs
- Leak traced before you get a price
- 10-year waterproofing warranty
Leaking Balcony Repairs
Water in the room or unit below, drummy tiles, pooling that never dries. We repair houses, townhouses and whole apartment blocks, and quote strata direct when the balcony is common property.
- Resin injection through existing tiles
- AS 4654 compliant membranes
- 5-year workmanship warranty
Fixed without removing your tiles
The traditional fix is to demolish the shower or strip the balcony, lay a new membrane and retile it. It works, and it costs a fortune, takes a week and leaves you without a bathroom.
We use resin and epoxy injection instead. The resin is introduced through the existing grout lines and travels into the cracks and voids in the substrate below, then cures into a sealed barrier — through the tiles you already have, without touching them.
We diagnose before we quote
Water travels. The stain on the ceiling is rarely under the place it is getting in, so we trace it and photograph it first — that is what an evidence-based quote actually means.
Most jobs, no tiles come off
No demolition, no skip bin, no matching a discontinued tile. Most repairs are finished in a day and you keep the bathroom or balcony you already have.
Warranted in writing
10 years on shower waterproofing, 5 years workmanship on balconies, 60 days on service work — supplied with your invoice.
When injection is not the right answer, we say so. If the falls are wrong or the slab itself has failed, no amount of resin fixes that — and we will show you the evidence before recommending the bigger job.

The rest of what we do
Everything here is waterproofing work we do ourselves — we are not subcontracting your bathroom to somebody else.
Leak detection
We trace the entry point before quoting, and photograph it, so you are paying to fix the cause rather than the symptom.
Regrouting
Perished, cracked or missing grout raked out and replaced — the most common reason a sound shower starts leaking.
Epoxy grout
Non-porous and far harder wearing than cement grout. The right call in wet areas that have already failed once.
Shower waterproofing
Resin and epoxy injection that seals the substrate under your tiles, backed by a 10-year warranty.
Bathroom repairs
Failed junctions, cracked tiles, tired silicone, waste and hob detailing — the repairs that stop a full renovation being necessary.
Bathroom renovations
When a bathroom is genuinely past repair we rebuild it properly, waterproofed to standard from the substrate up.

Meet Ray

“I have been fixing leaking showers and balconies across Sydney for over a decade. I will come out, find where the water is actually getting in, and give you an honest quote — not a guess. Most of the jobs I repair do not need the tiles taken up, and I will tell you plainly on the day if yours is one of the ones that does.”

On-site inspection

Repair & warranty
Sealed, tested, and covered in writing — 10 years on showers, 5 on balconies.
The things people ask first
Do you have to remove my tiles to fix the leak?
Usually no. Our resin and epoxy injection system seals the substrate through the existing tiles, so the shower or balcony stays intact. We only recommend a full strip-and-remembrane when the falls are wrong or the slab itself has failed — and we show you the evidence before you commit to that.
How much does a repair cost?
Balcony repairs land between $1,499 and $6,000, depending on the size of the balcony, the condition of the tiles and grout, and how far the water has already travelled. Showers are quoted the same way. You get a fixed written price after the on-site inspection — no hourly rates and no surprises on the day.
What warranty do I get?
10 years on shower waterproofing, 5 years workmanship on balconies, and 60 days on service work. All of it supplied in writing with your invoice.
Which parts of Sydney do you cover?
Sydney metro, Inner West, Southern Sydney & Macarthur. We are based in Campbelltown and travel across the Sydney basin — call 0424 626 557 to confirm your suburb.
My strata says the balcony is common property. Can you still help?
Yes, and it comes up constantly. We provide a written, photographed report identifying the leak source, which is exactly what owners corporations and strata managers need in order to approve the work. We quote the strata directly if that is easier.

$1,499 – $6,000Typical balcony repair, fixed in writing
Where a job lands in that range comes down to three things:
- The size of the balcony or shower
- The condition of the tiles and grout
- How far the water has already travelled
