What is efflorescence, and why does it keep showing up on balconies, tiles and brick in Sydney buildings?
It's the white powdery substance that comes out on top, it can look like dirty grout, and in my experience it typically means a waterproofing issue.
In this episode I explain what's happening, why it can lead to concrete cancer if it's left unchecked, why I see it more and more often in newer buildings, what I've seen quoted to fix it, and why the strata report is where you look next.

Listener FAQs
What is efflorescence?
It's the white powdery substance that comes out on top of tiles, grouting, brick and very often balconies. It happens when crystals come into contact with water and rise to the surface. In my experience it typically points to a waterproofing issue.
Is efflorescence just dirty grout?
It can look like grouting that hasn't been cleaned, but in my experience it typically means a waterproofing issue. Left unchecked, it can cause things like concrete cancer, and it's extremely expensive to fix.
What should I do if I see efflorescence when I'm looking at an apartment?
I'd look into the strata report as soon as possible, to understand where the building is in the process of fixing it. I've seen quotes of around $60,000 to $80,000 per balcony, and the longer it's left, the more damage it can cause. If you're unsure what a strata report means for your own purchase, talk to your solicitor.
Is efflorescence more common in newer buildings?
In my experience I see it more and more often in newer buildings. I'm not saying it's only newer buildings, because efflorescence and concrete cancer exist in older buildings too.
Is concrete cancer more common near the beach?
In my experience concrete cancer is more prevalent where conditions are harsher, with more salt in the air. If you're thinking of the eastern beaches, even the 70s and 80s buildings have battled with it in quite a few cases.

Michelle:
Hi and welcome to another episode of the Buy Your Side Podcast, the property podcast to help you make smarter property buying decisions. My name is Michelle May and I am the principal of Michelle May Buyers Agent here in Sydney. Now, if you're watching me on a video on YouTube or maybe social media, do you know what this is behind me? This is what they call efflorescence.
Efflorescence is the word of the day because I come across it so often and I realised that most buyers do not know what this is. So to describe the picture to you, if you can't see me, it is tiles with a white powdery substance that is coming out on top. It looks like you haven't been cleaning your grout very much, so you often see this on common areas where there's tiles or where there's bricks, but also very often on balconies. Now, the reason why I wanted to bring this to your attention, because it is a very costly thing to fix. So efflorescence in essence is when the crystals come into contact with water and then they rise to the surface and that's what creates this white powdery substance in layman terms. The reason why you need to keep looking out for this is because it actually means that there is typically a waterproofing issue, okay? And if left unchecked, it could actually cause things like concrete cancer, which obviously concrete cancer is a very scary thing.
For a building to have it left unchecked because it can actually disintegrate the whole structural integrity of a building and not only that it is extremely expensive to fix. The reason why I want to bring this to your attention also is because this is something that we see more and more often in newer buildings and when I say newer buildings I mean the ones that were constructed after the year 2000 in New South Wales. The reason for that, in my humble opinion, is because of privatization of certification. So, around the year 2000, councils in their great wisdom decided that instead of using in-house certifiers to sign off on buildings as the build progressed, they themselves would go, check and give them a sign off on whether things were finished and built correctly, in accordance with the Building Code of Australia. They decided that it would be in the best interest of everyone to hand that job of certification over to a private certifier because they thought that would speed up the whole building process. By doing so, they put the private certifier in the hands of the builder and developer because now the builder and developer has to pay a private company, a private person, to come and sign off on the job.
Now, I don't know if I need to spell this out to you, but of course this is a glaringly obvious conflict of interest because no private certifier is going to be in the job much longer if they keep, writing off these projects because things are not being done correctly or if nothing else it is a huge incentive to not look at things too closely right? I mean look I don’t think I'm sharing anything hugely controversial there because it's human nature so when you go and look at buildings or when I go and look at buildings post-2000 you can definitely tell the difference in the build quality in many, many cases and I'm not just talking about small little developments. I am talking about some of these national builders that really should be ashamed of themselves by the way they are constructing things nowadays and one of the most obvious ways, a telltale sign, is efflorescence.
To understand where they are in the process of fixing this because just to give you a ballpark idea I've seen quotes of around sixty to eighty thousand dollars per balcony, to fix this because the longer you leave this the more damage it can cause to the structural integrity of the balcony.
If this is in a basement this can cause structural integrity to the basement and therefore the whole building on top. Now I think that in most cases, people will look at it and think, it just needs a good scrub, but it's far more sinister than that. Of course, concrete cancer exists in older buildings, efflorescence exists in all the buildings, in older buildings they didn't even have any waterproofing at all up to a certain period.
So of course, I'm not saying this is only in newer buildings, but it's something to look out for. Now concrete cancer is more prevalent in areas where there are harsher conditions. So when there's more salt in the air, so if you're thinking of the eastern beaches, for example, those buildings, even the 70s and 80s buildings will have battled with concrete cancer in quite a few cases because of that wind obviously bashing against these facades and again it's really up to the strata community to spend time and money investigating the severity of this and let me tell you the longer you leave it the more severe it's going to get it's not just going to go away so I just thought I'd bring this piece of information to you today. Efflorescence. Look it up, have a look at the pictures and next time you go and look at an inspection make sure that you check for efflorescence.
Now if you enjoyed this episode give me a like and follow, thank you so much but also I want to just let you know that I have a clarity challenge coming up. It's a free challenge for 10 minutes with me, three days in a row Tuesday to Thursday the 14th to 16th of April.
