mould

So I have a black mould stop at the top corner of my house. I believe it's a cold wall and we have high humidity causing it. It is always around 80 this time of year. Before looking at PIV systems which will take time to research I thought I would look at a possible cause. On one of the same...

I have an artexed bathroom ceiling which was painted with some dulux bathroom paint about 9 years back. Its grown mould and has started peeling and cracking (aligatoring ) in areas. So far I've scraped what i can peel off but restricted due to it being artexed and then I've wiped it down with...

Hi I have a top floor bedroom where where at the external corner of the house there is a cold spot and where mould keeps forming. See the thermal image here. How are cavities formed around corners? Any ideas of the next step ? I don't think I can get a camera down the wall cavity that has the...

Hi, I have some loose bathroom tiles near the shower that we're actually growing mushrooms from, and they were also growing on the other side of the wall. They have been up over 20 years. Will letting the wall dry out, spraying with diluted bleach and re tiling be sufficient or should I do...

Hi all. We moved into a new build flat 3 years ago and have been having issues with damp and mould in the utility cupboard from about 3 months after we moved in until now. When we originally brought it up with the builder they told us that there was a leak coming from outside where a drain...

I've just popped into the loft to get something out, and found little black dots covering pretty much the entire space. They're not evenly distributed, and are relatively new (last couple of months - we had a hot water cylinder installed at that time, and they 100% weren't there then). They're...

Hi all. I have a patch of mould on my bathroom ceiling that I want to get rid of and prevent coming back. However, there's a few things I'm not sure about. I'm planning on doing the following: 1.) Cleaning off the existing mould with an anti-mould spray 2.) Applying a stain sealer to stop any...

Hello, We have mould appearing on the internal plywood of our garage roof in the past few weeks during the colder/wetter weather. I wondered if anyone could give an insight into why this might be happening? The mould appears between every joist front to back, mainly appearing from the edges but...

Hi all - I wonder if anyone can help advise on these black spots along the window panes.. it looks like mould to me.. Does anyone have experience of this - do the windows need replacing or is it just a case of replacing the seal? Does this suggest a problem with ventilation? Thanks for any...

Hi there, I was wondering if someone might be able to help me. I've moved into an old rental terraced property with a lot of black mould problems. We're pretty good with wiping condensation, never drying clothes indoors, cooking with lids on extractor fans etc, but it's pretty consistently...

Good evening all, hopefully someone can give me a bit of advice on the following. I'm a Mechanical Engineer by trade but pretty novice when it comes to household stuff, so apologies in advance! We have lived in a house built in approx 1960 for a few years now and have noticed that we keep...

Hi, can anyone confirm whether the black stuff in the photos is mould? I think it may be mould but perhaps covered in dust, so I’m not sure. The photos are from an old disused fireplace that is now simply a hole in my bedroom wall with a breeze coming through it. I’m on the top floor with two...

We have a no cavity Victorian semi which we have always had a problem with cold outside walls attracting condensation. The inside of the wardrobe cupboard wall facing outside is pretty wet, making clothes damp and leading to mould. Ditto for bedroom wall. Having a log burner installed, warming...

Hi all I hope you're all keeping well This is my first post and I'm hoping to get some advice on a case of extreme condensation in my loft. I've read the various threads I could find, but wanted to get your take on the solutions I've been offered by several roofers before taking the plunge. I...

Hello DIYnotters! Got a few questions regarding damp but some useful info beforehand: Property is end terraced, built around 1990, in Swansea, no subsidence/coal mining nearby and lastly - the house has ventilation grills that cover holes drilled through to the exterior of the building in...

We had this downstairs toilet room fitted 4 years ago. No problems until now, and no other damp anywhere, just this patch that’s between the toilet pipe and the sink unit. Who should I call? Damp specialists want a lot of money for a full survey, so should I call a plumber first? my guess is...

Hi, My cellar, which has always been a little damp seems to have got much worse over the past few months. During some really bad rain I could actually see it seeping through the walls and pooling up on the floor. I've had the guttering cleared as there was some overspill at the time. I was...

I've just bought a new house and went to start the prep for painting one of the bedrooms. I took the radiator off to discover it was mouldy behind. I didn't realise it was lined with paper. Is there an easy way to fix this without having to re-paper the whole room? Suggestions would be greatly...

Hi, There's a mouldy smell in my shower room, and I think it may be coming from the extractor fan. I removed the cover and cleaned around the motor and blades, which were pretty black, but I couldn't reach into the ducting. First, I'd like to know if mould in extractor fan ducting is a thing...
