Balcony Waterproofing

Done once, done right

A balcony is really a flat roof you walk on, and like any flat surface it lives or dies by its waterproofing. When the membrane under the tiles cracks, or the seal around the drains and edges lets go, water works its way under the surface and into the structure. The first sign is usually a stain or bubbling paint on the ceiling of the room below, and by then the water has already been getting in for a while.

We track down where the balcony is actually leaking, strip back the failed waterproofing, and re-seal it properly: the membrane, the drainage points, the edges and the junction where the balcony meets the wall. Done right it protects the room below and the balcony structure itself for years, and it is exactly the careful, water-tracing work our family has done for three generations.

What balcony waterproofing costs

There is no honest flat rate for this job, and anyone who quotes you one over the phone has not looked at your roof. Here is what actually moves the number.

We quote fixed, in writingWe come out, get on the roof, and give you one clear price. The price we quote is the price you pay, and the inspection and quote cost you nothing.
Balcony size

The area to be stripped and re-membraned is the starting point, but it is rarely the biggest factor.

Whether the tiles come up

Lifting tiles, re-membraning and re-tiling is the thorough fix. Some balconies can take a coating over the existing surface. The right answer depends on what we find, not on which is cheaper.

Drains and edges

Most balcony leaks are at the drainage points, the edges and the junction with the wall. Detailing those properly is the work that makes it last.

How far the water has got

If it has been leaking for years and reached the structure underneath, that has to be dealt with before any membrane goes down.

How to tell

Signs you need balcony waterproofing

If any of these sound like your place, it is worth getting looked at before the next big rain. Spotting it early is almost always the cheaper repair.

Tiles that sound drummy or hollow underfoot
Water pooling on the balcony instead of draining away
White powdery efflorescence on the underside or the edge

How this job runs

What happens when you book balcony waterproofing

No sales visit, no pressure, and no work starts before you have seen a fixed written price.

01

Find where it is actually getting in

A balcony is a flat roof you walk on. The leak is usually at a drain, an edge or the wall junction, not in the middle.

02

Strip back the failed membrane

The old waterproofing comes out rather than getting covered over, because covering a failed membrane just hides it.

03

New membrane, properly detailed

Membrane laid, then the drains, edges and wall junction detailed. That detailing is where balconies live or die.

04

Water test before tiling back

We flood test it and watch the ceiling below before anything goes back on top.

What does balcony waterproofing cost in Sydney?

The size of the balcony matters less than whether the tiles have to come up and how far the water has already got. A small balcony with structural damage underneath can cost more than a large one caught early, which is why we look before we quote.

Do the tiles have to come up?

Not always, but often. Where the membrane underneath has failed, going over the top traps the problem. We will tell you honestly which situation you are in, including when the cheaper option is the right one.

Can you waterproof over existing tiles?

In some cases yes, with the right system and if the tiles are sound and well bonded. It is a genuinely good option on the right balcony and a waste of money on the wrong one.

How long does a balcony membrane last?

A properly laid and correctly detailed membrane lasts many years. The failures we get called to are almost always detailing failures at the drains and edges, not the flat middle section, which is why we spend the time there.

How long before we can use the balcony again?

Membranes need curing time before anything goes back over them, so allow several days from strip to finished. We give you the actual timeline when we quote.
