Leaking balcony repairs Toorak

• Terraces over habitable space A roof terrace over a living room is a roof, not a balcony, and it needs to be treated like one. When these leak the damage is immediate and expensive because it lands on finished interiors rather than a carport.
• Level thresholds and flush doors The flush indoor-outdoor threshold that looks so good is the single most common failure point we find in the area. Without a properly formed and drained threshold detail, water sits at the door and tracks straight inside.
• Planter boxes and built-in landscaping Planters built onto a terrace hold permanently wet soil against a membrane and a wall. Unless they were tanked separately with their own drainage, they will eventually leak into whatever is below.
• Glass balustrade fixings Spigots and channel fixings bolted through a membrane are deliberate holes in your waterproofing. They need to be sealed as part of the system, not siliconed afterwards.

A stain on a ceiling is rarely directly under the hole. Water that gets through a balcony membrane runs along the slab until it finds a way down, so the damage can appear metres from the entry point, or in the next apartment along.

Look for: a stain or blistering paint on the ceiling below, efflorescence (white chalky salts) on a soffit or garage ceiling, rust staining or flaking concrete underneath, damp skirting boards in the room below, tiles that sound hollow when tapped, cracked or missing grout along the wall junction, water pooling on the balcony after rain, or a musty smell in the room under the balcony.

Almost every balcony we are called to has already had someone silicone something. The reason those repairs do not last is that nobody established where the water was getting in before they started.

1. 01On-site inspection. We look at the balcony, the room below, the junctions, the drainage and the soffit, and we ask when the staining appears — after rain, after a certain wind direction, or all the time.
2. 02Water testing where it is needed. We isolate and flood-test sections in sequence so the entry point proves itself rather than being guessed at. See balcony water testing.
3. 03A written report with photos. What we found, where the water is entering, and what the repair involves. This is what owners corporations and insurers need.
4. 04A quote for the actual repair. Priced on what the balcony needs, not on a guess.

Not always, and this is worth asking before you accept a quote that assumes they do. Where the failure is confined to a junction, a threshold, a drainage outlet or a section of the balcony, we can often repair that area and re-waterproof it without stripping the whole floor.

Where the membrane itself has reached the end of its life across the whole balcony, a full strip and re-waterproof is the honest answer, and we will say so. What we will not do is quote a full rebuild on a balcony that does not need one, or patch a balcony that does.

We install Kerakoll waterproofing systems, and our director is a certified Kerakoll waterproofing specialist. Where a full system is installed to specification, the manufacturer warranty applies on top of our own workmanship warranty. Where balcony movement cracking is involved we are also a licensed HeliFix installer — see HeliFix crack stitching.

On larger terraces we normally start with water testing, because guessing on a terrace of that size is expensive. We isolate sections and test them in sequence until the entry point shows itself, then quote the repair for that.

We provide written inspection and defect reports with photographs, suitable for owners corporation meetings, insurers and building managers, and we are fully insured.

Balcony leaks rarely travel alone. We also handle concrete crack and spalling repairs, render crack repairs, cladding repairs and HeliFix crack stitching where structural movement is part of the picture.
