Mould, rising damp - UGH
- Topic Author
So, she's been having allergy problems like never before that I've just put down to general damp/moulds of winter, as we've also got window condensation like never before this winter, and there is black mildew in some of the windows which seems to crop up really quickly (I wash them off once a week or so).
So, to my horror when preparing to rearrange her room this past week while she was away, I found a huge patch of black mildew up the wall next to her bed and white mould/fungus IN the carpet under her bed in the same corner of the room, and a bluey stuff on the surface of the wood floor under the carpet. It was growing in a long pillow that was against the wall, and I can only assume it's in her mattress (which is only a year old!!!) as well.
We plan on demolishing the back end of the house to re-build with a second storey, but it isn't factored into the saving budget for at least 18 months. What can we do in the meantime to make her room safe? She was complaining of a tight, painful chest this evening, which DH says is classic asthma symptoms he had really badly as a child. Will be taking her for tests this week, big fun. Not.
In the UK there was one product I used a lot for treating rotten wood. As long as the wood still had some strength left in it, you painted on this liquid onto it. It killed the mold, but also penetrated the wood and created an epoxy resin in the wood itself and hardened the wood. Any holes in it were easily filled. Oh before using the product you got rid of the really soft wood first.
We had a similar problem with son's bedroom. The outside water tap was in that particular corner (still is) and it was leaking making the wall wet from inside the wall cavity but only a bit so that it wasn't obvious. We had the gib board removed and replaced, insulation and building paper installed and new bricks from the outside so that only the framing timber stayed the same. I can only recommend doing this. The room used to have a stale smell and black mould growing on the wall in the corner - now it is fine.
We had tried mould killer before that, also taking the wallpaper off, paint-on mouldkiller and then re-wallpapered. That lasted half a year. If the mould is in the wall it doesn't go away.
I would take the gibboard off right now, spray everything out with mould killer, put in insulation and put some gibboard back on. Poster on top - finished - until you do your renovations. And I would cut a bit of the carpet out, too, clean the floor boards thoroughly, put on mouldkiller.
Can you take her mattress out of her room, leave it for a while and smell it then? I reckon mould has a certain smell so maybe you can ascertain whether the mattress is affected.
Well you will need to find the source of that dampness. Check the roof. And also the spouting.
What sort of construction is the house?
But in the mean time I suggest you get yourself a dehumidifier in the room to dry it out.
Is the wall the damp on, near where the lean to starts or at the bottom end. It could be a flashing problem or even a bit of rusted roofing iron.
But whatever, I think you will have to replace the gib where the damp is worst so get in and rip some off. Unless you can find the actual source of the problem everything else is just cosmetic.

A small oil column heater for that room, coupled with the dehumidifier would help. Dehumidifiers work better with warmer air.
This will pump up your power bill, but...

Skyline Glenn, we're going to pull up the bathroom floor (right on the other side of the wall from her room) to see what's what in that corner, because there may very well be standing water there. In examining everything more closely, I've just noticed that at the foundation there, right where the mould is on the inside, is a great chunk of MISSING foundation and a big blob of concrete poured back in under the house. Will be looking at this more closely next weekend, as there's only so much I can do with my bad back. Will have to wait for DH to dig around under there. I'm wondering if some standing water couple with no ventilation under the house there is causing problems in this very damp winter.
Just coming down with a cold, unfortunately, my annual one, always this time of year, so I'm not going to mess with bleach or a mouldy room, so it will have to wait, but yes, I must stock up on the bleach, because I intend to use it straight!

builders are shocking for not using enough flashing or for not bending where appropriate....
