I’ve never been a great fan of bad smelling houses. I can’t tolerate living in places that wreak of mould. We’ve seen quite a number of properties with serious waterproofing & ventilation problems here and quite a few real estate agents seem to turn a blind eye to it.
In one place, all the curtains on the windows had mould. The indoor air smelt terrible. Real estate agent’s response:
Oh, that’s only because the house hasn’t had a good airing for a long time. You just need to open the windows to clear it out.
Yeah right. Cuh! If only i could convey just how bad things were smelling in the underhouse storage area of that house! :O When mould starts beginning to form on curtains - the house has a problem with adequate ventilation & waterproofing. If I see moss or other moisture growing near the corners of the bottom of the house, I know that the house i’m living in will be prone to rising damp. My experience of living in this house, has taught me how important it is for things to be well waterproofed from the top too.
The floor tiles in the bathrooms & laundry here have been a major source of stress. This was the problem we were facing when we first moved in - a photo of the ensuite’s shower recess…
The tiles for the ensuite & laundry were all loose with a hollow tap. If we walked with bare feet, the tiles would lift off the floor. If your tiles are like this - you’re going to face a bad waterproofing problem - which will not only damage & loosen the tiles further, but will cause problems with mould that will damage the house further.
This is the patch up job that was done to waterproof the shower recess in the ensuite with the rather artistic application of silica gel around the corners.
With the tiles being in such bad condition, water was getting underneath them and creating mould underneath the silica gel. No amount of domestos could remove or bleach the mould living inside the silica gel. With water getting underneath the tiles, this is what was happening to the room adjacent to the shower.
Maybe some people can comfortably live with that but it would be a red flag for me if i owned this house. We put in a request for repairs to the real estate agent. It took 3.5months before something was done about it.
There were two tilers that came in to review the tiles. One was happy to go ahead with the bandaid solution, quoting about $2000AUD for the job. Another tiler refused to accept the job because in his opinion, everything needed to be ripped out and done all over again properly, otherwise the house would continue to experience the same problem, quoting $6-8000AUD for the job.
Naturally, the landlord opted for the cheaper “patch up” job and while the tiler did a great job, here’s an account of what’s happened since. The entire floor of the laundry was ripped out and resurfaced with new tiles, but whenever it rains, we now get puddles of water entering into the room! The section near the door is always very wet. Take a look at what having that much water lurking on the floors like this is doing to the wall now!
Pretty bad huh? This corner of the laundry had a very small amount of mould building up in this corner before. Since the installation of the new tiles - the problem has grown monumentally worse. The wall, door frame & the bottom of the door are beginning to rot & decay at an alarming rate now.
The door is unable to open properly all the way too. The level of the new tiling to blame at first, however if the door continues to get water logged & begins to expand even further - i’m quite sure it’ll be even harder to open the door.
Extending the floor tiling like this to the outside was not a good idea. As the floor must have a “dip” to allow excess water to run into the drain hole, you can’t defy the laws of gravity - so this is why water has begun to enter into the laundry from the outside when it rains.
This is an external shot of the laundry’s exit showing the roof line, which i think it the real source of the problem. Not much awning space there to shelter the rain from hitting the side of the house.
Another external shot of the house further down this side of the house. The guest bathroom where the window is. There’s even less roof awning here and it doesn’t have any gutter either!
The house is about 15yo. At first I thought the reason for why the tiles were getting loose was due to settlement issues with the foundations shifting. I’m now convinced that the real cause is due to inadequate waterproofing from the roof & sides of the house. With the rain hitting the side of the house, water is getting logged into the red cedar walls and making it’s way underneath the tiles and other parts of the house, which is causing other non-waterproof materials & structures living underneath & inside the house to expand. The outside of the house is probably well overdue for another paint job to treat the wood. I wonder just how overdue too, because the garden was clearly neglected for at least 8 years before we moved in.
The following is a shot of our walk-in wardrobe. It had a serious moulding problem here before we moved in. I’ve cleaned it up since, so it doesn’t look as bad as it used to.
The source of the problem was the roof. A piece of metal flashing was installed into the corner of where the roof meets the wall.
The workroom space in this corner downstairs was also smelling a little mouldy. While the flashing has helped the problem considerably - I can also see how it’s still a temporary solution as you can see how the water is getting logged into the red cedar around the edges of the metal roofing in the picture above.
A shot from the back of the house. The window on the left, is my son’s bedroom. The window on the right is the ensuite adjecent to it. Again - not much awning form the roof nor any guttering to protect the sides of the house from rain, with some parts of the red cedar getting water logged.
There’s also another problem with the branches of the pine tree next to the corner of the house overhanging on top of the roof too. It’s allowing too many pine leaves to sit on top of the metal roof, which i’ve been told an lead to corrosion due to the amount of acidity in the leaves. The branches grate against the roof during windy weather too. Another reason for why it’s not good to have pine trees tower on top of your roof here? It’s because the cockatoos are going to spit the pine cones onto your roof and wake you up with loud bangings at 5am in the morning. *lol*
Another shot of what things look like on the outside of the ensuite.

An here’s what things are like on the inside of that window. There’s mould beginning to form on the curtain.
I’m a strong advocate for the use of exhaust systems to suck up the excess moisture & steam during showers out of rooms as they’re very effective at preventing the formation of mould, but it’s obvious that the exhaust system for the ensuite is not working properly at all.
The regular light in the ensuite has been broken since the first day of moving in. Never trust real estate agents who promise that things will get fixed when it’s spoken through their mouths. It never gets done, so it always makes me laugh when they try to be & sound so bloody sincere during the periodic inspections. *lol*
The problem I’ve found with exhaust systems pumping out air towards the roof of the house, is that they have a tendancy to bring far too much dust back inside. I don’t know of any sytems that pump moisture “out” of the house through the side of the wall, but i would definitely consider investigating it further in the event of building my own home.
With the master bedroom adjacent to the ensuite being lined with carpet - this room will eventually begin to smell very mouldy if the exhaust system is not fixed soon. Let’s now take a journey to the front of the house and check out what the awning of the roof is looking like over here…
You can see how the water is getting logged into the wooden decking and how it travels towards the side of the house where there’s a water shoot extending down from the gutter. It was a very poor building & construction technique to allow the decking to penetrate into the side of the house like this. The water logging has caused this side of the house to expand, pushing & warping the wooden window frames too.
A shot of the roofline on the front verandah, where again - there’s not much awning to protect the house from getting hit by rain on the sides.
As for the bandaid solution on how to fix this problem?
…yeah, let’s just shove some more silica gel in to fill up the cracks! *lol* Oh well - at least it helped to prevent some of the cold drafts coming into the house last winter. =P
The guest bathroom tiles are currently in a very shocking state, where they’re all becoming very loose and experiencing the same problem of lifting off the surface when you walk on them with bare feet. The rate of damage has been increasing rapidly. The more water that gets onto the tiles and falls in between the grouting after a bath in this room, the worse the problem gets. As the former landlord has sold the house, it’s obvious that our request for repairs has been totally ignored, so we’ve just had to live with this shit.
I look forward to moving out of this house next week, because those tiles have been shitting me just as bad as biege coloured carpet in the former rental appartment we were living in the inner-west suburb of Sydney known as Newtown. {*gah!*}
The real estate sales pitch on the house when it was put up for sale, had words along the lines of,
“Recently renovated!”
- which has highlighted to me why it’s really important to investigate and find out what the reasons for the specific renovations have been, along with a details of the actual work that was carried out, before you buy a house. It could very well be a patch-up job covering up a much bigger problem.
It’s been a really interesting experience for me to watch & learn from. This house has thankfully not smelt too moudly since we moved in, but i can see how the problem is going to get worse if people don’t pay attention to the current problems it faces and have them resolved soon.
Here we’ve had the tiler’s focusing all of their attention onto the floors, when the real source of the problem has probably been the bloody roof. For now - i’m grateful that i don’t own this house, because the amount of money required for repairs & maintenance to keep it in good shape is literally going to be….
…through the friggin’ roof!
