Your Tiled Balcony Is Leaking Through the Grout. We Fix That — Properly.
Outdoor exposure makes it worse, faster. Sun, UV, and Perth's rain cycles break down balcony grout and silicone significantly faster than any indoor surface. Most homeowners don't notice until water appears somewhere it shouldn't.
Tiled balconies leak through grout lines and silicone joins — exactly like a leaking shower, but outdoors every day. Surface Seal re-grouting, re-siliconing, and epoxy seals tiled balconies to stop the leak and protect the slab. Done in 24–48 hours. 10-year warranty. Concrete driveways sealed too.
Your Balcony Tiles Look Fine. The Grout Between Them Doesn't.
Most homeowners don't notice their tiled balcony is leaking until water appears on a ceiling below or a wall starts showing damage. By then, the slab has been absorbing water for months. Here's what's actually happening.
Why outdoor grout fails faster
Every single day, your tiled balcony faces conditions that no indoor shower ever does:
- Sun & UV — bakes the grout dry, hardens and cracks silicone away from tile edges over 1–2 summers.
- Constant rain cycles — the wet/dry cycle expands and contracts grout joints, working them loose from within.
- Perth's temperature swings — hot summers and cool winters cause the slab to flex, opening micro-cracks in grout lines.
- Wind-driven rain — forces water into joins at angles that gravity-fed indoor shower water never reaches.
The same fix we use on leaking showers
It's the same problem as a leaking shower — so the treatment is the same. Done in 24–48 hours, no demolition required.
- Re-Grouting — deteriorated grout removed and replaced with fresh, correctly mixed and finished grout at all tile joints.
- Re-Siliconing — old silicone fully stripped from all joins; new silicone applied in one clean continuous bead.
- Epoxy Coating — professional-grade epoxy applied over the entire surface, bonding to tiles, grout lines, and joins. Creates a continuous water-resistant barrier.
- Non-Slip Finish — non-slip aggregate added as standard. Essential for outdoor wet surfaces.
Tiled Balconies. Concrete Driveways. One Trade, One Visit.
The same professional-grade epoxy system Surface Seal uses on leaking shower interiors applies directly to tiled balconies — same process, same product, same warranty. Concrete driveways and slabs are handled with the same approach on bare surfaces.
Tiled Balconies & Elevated Slabs
Your Most Overlooked Leaking Surface
Tiled balconies are the most under-maintained leaking surface in Australian homes and strata buildings. The tiles look intact — the grout and silicone joins between them have deteriorated, and that's where the water gets in and starts damaging what's underneath.
We treat a tiled balcony exactly as we treat a leaking shower: re-grout every joint, replace all silicone, and apply epoxy coating over the entire surface. The result is a revitalised balcony that looks new and is sealed beneath to help reduce water ingress.
Concrete Driveways, Paths & Slabs
Seal It Before the Staining Takes Hold
Unsealed concrete driveways absorb oil, fuel, and rainwater. Left untreated, staining becomes difficult to remove and the surface deteriorates with every rain cycle. Our epoxy bonds from within — not from the top — creating a barrier that repels oil, resists UV, and makes the surface dramatically easier to maintain.
The wet-look finish enhances the natural concrete colour without looking glossy or industrial.

Photos & Assessment
Send a few photos. We assess the grout, silicone, and surface condition remotely within 24 hours and confirm scope and quote.
Surface Prep
Old grout cut back. Silicone fully removed. Surface cleaned and dried. Correct prep is the foundation of a lasting bond.
Re-Grout & Re-Silicone
Fresh grout applied and finished professionally. New silicone applied in one clean, continuous, correctly tooled bead at all joins.
Epoxy Coating
Professional-grade epoxy applied over the renewed surface — bonding to tiles, grout, and joins. Non-slip aggregate added as standard.
Cure & Handover
Balcony out of service for 24–48 hours. Written warranty and written aftercare provided. Ready to use the following day.
Tiled Balconies & Driveways — Residential to Commercial.
Homeowners
Your tiled balcony grout is crumbling or the silicone has pulled away. Maybe there's a water stain on the ceiling below. We assess, treat, and seal — one visit, 24–48 hours, done properly.
Strata & Body Corporate
A leaking tiled balcony in a strata building causes damage to the unit below — and the committee is liable. A sealed balcony is a proactive investment, not an optional extra.
Commercial & Facilities
Commercial balconies, aged care facilities, and car parks need a durable, sealed surface that holds up under heavy use and doesn't create slip or water liability.
The Same Epoxy. Used Indoors Too.
Got a leaking shower as well? One trade, one visit, both jobs done. We bring the same system indoors for shower resealing, re-grouting, and re-siliconing.
Honest Answers. Plain Language.
Why does my tiled balcony leak even though the tiles look fine?
Because the leak isn't coming through the tiles — it's coming through the grout lines and silicone joins between them. These deteriorate much faster outdoors because Perth sun and rain cycles break down grout and silicone significantly faster than indoor conditions. The tiles look intact because they are. The joins between them aren't — and that's where the water gets in. The fix is the same as a leaking shower: re-grout, re-silicone, and epoxy seal.
How is sealing a tiled balcony different from sealing a shower?
It's essentially the same process — which is exactly why Surface Seal is well-positioned to do it. The grout lines and silicone joins on a tiled balcony fail for the same reasons as those in a shower. The key difference is speed of deterioration: outdoor exposure to sun, UV, and rain causes grout and silicone to break down significantly faster. Our treatment is the same: re-grout, re-silicone, and epoxy coating applied over the entire surface.
How long does it take for my balcony to be useable again?
After the full treatment — re-grout, re-silicone, and epoxy coating — the balcony needs 24–48 hours before it can be used. We provide written aftercare instructions on the day. We also check weather forecasts before scheduling and will not apply epoxy if rain is expected within the curing window.
Can you seal a tiled balcony without removing the tiles?
Yes — that's the point of the service. We re-grout the existing tiles, replace the silicone at all joins, and apply epoxy coating over the surface without any demolition or tile removal. The only exception is where tiles are lifting, severely cracked, or the waterproofing membrane beneath has comprehensively failed — in which case we'll tell you honestly rather than take a job that won't hold.
Is the non-slip finish suitable for an outdoor tiled balcony?
Yes — and it's important that it is. Our outdoor applications include a non-slip aggregate finish as standard. Balconies get wet every time it rains, and a smooth epoxy surface without aggregate would be a slip hazard. The non-slip finish is part of the standard application — not an optional extra.
How much does tiled balcony sealing cost in Perth?
Pricing depends on the size and condition of the balcony, whether re-grouting and re-siliconing are required alongside the epoxy, and accessibility. Send us a few photos with rough dimensions and we'll come back with a clear itemised quote within 24 hours — no site visit required.
How long does balcony or driveway sealing last?
Our professional-grade epoxy bonds to the substrate rather than sitting on top as a film coating. Unlike consumer-grade sealers that wear off in 12–18 months, this is a long-lasting bond — not a seasonal product. We back every job with a 10-year written warranty. Longevity depends on surface condition, preparation quality, and type of use — all of which we factor into the assessment.
