mould

My combi boiler is attached to an adjoining wall, with the flue, overflow etc going out the external wall. We noticed a damp/foisty smell in the cupboards and when I went investigating, found that the wall in which the boiler is attached to had a damp patch below it and white mould. All the...

I'm ideally looking for reassurance my own non-invasive investigations have reached a conclusion that makes sense before I engage a professional. And I'm looking for guidance as to who that professional should be - I'm obviously thinking Plumber right now. I have a bathroom with toilet, sink...

The hallway subfloor seems to get damp, especially if it's been raining heavily outside. Do you think it would be a sensible solution to apply slurry to this floor, and the walls below the floorboard level to prevent this? I don't want to make a mistake before putting the floorboards back down...

I moved into a house that had a hidden leak. I stopped the leak and replaced the affected floor joists and boards. Months later the smell remains, but there are no visible signs of concern. Is this normal? Do I need to treat surrounding wood to prevent smell? What's going on?

There was a hidden leak under my suspended timber floor. The timbers developed wet rot and the surrounding space became mouldy. The area has now been replaced with fresh timber joists, and the leak has been fixed. I'm concerned that mould could occur again. What is the best wood treatment to...

Living room has a 3m long freezing cold external wall, brick with zero insulation. It’s free of windows, doors, and power outlets, a completely blank wall except massive new split system installed up high. I don’t want to move the slit system. I’m thinking about building a half-height “wall”...

Hi there, I recently had some night storage heaters removed and while sanding to prepare the wall where the heater was for painting, this pink stuff appeared where I had sanded (white bits are filler). Anyone know what it could be? It seems slightly more pink than the plaster, but has been...

We’ve just had a new house professionally remediated for mould. We’ll need new ceilings ( = plastering) and parts of the walls need to be plastered. We’ve been advised to look at plaster bonding other than gypsum bonding, since this can apparently attract moisture. What type of plaster bonding...

So I live in an end terrace house. We have these damp patches in the back bedroom upstairs mainly on the gable end wall. We had the roof replaced around 2 years ago thinking that was the problem but it hasn't solved it. We are planning to have the gable end painted with a silicone breathable...

Hi Everyone, Recently when going into my loft to change the bathroom fan, I noticed that there was a huge amount of damp and black mould on around half of the timbers. I also noticed a smaller spot of what I think is white mould on one rafter and the felt around it. After investigating I found...

I had a walk-in shower installed just under a year ago and the sealant on the outside of the shower screen has gone mouldy. In fact, it started going mouldy some months ago, which seems a bit quick to spoil. The mould is behind/inside the sealant and is along the whole of the screen. The tiler...

Sorry double posting this as put in the wrong group initially so admins please feel free to shift where most appropriate. Hi We've been in a new build for 2 Years 3 months, within warranty time we've had them out for mould and condensation issues in the main bedroom, and damp patches in the...

Hi We've been in a new build for 2 Years 3 months, within warranty time we've had them out for mould and condensation issues in the main bedroom, and damp patches in the ensuite multiple times in same area (just kept painting over and stain blocking) Wednesday we noticed a watermark on...

Hi everyone, We are thinking of having a garden room built and need some expert advice as you never know if you can trust the builders! A single skin block construction has been suggested "with insulation". We wonder if it'd be suitable for our purposes and what kind of pitfalls should we look...

Hi everyone, I’m new here. My partner and I recently bought a terraced house, built around the 60s. The old wallpaper in our bedroom wasn’t done to a great standard, and we also struggle with mould which we think is affecting my partners breathing. We had a survey done when we were buying it...

Hi all, looking for some advice on a new project I am hoping to get done this month.... I'm planning to build some some built in bookcases in the alcoves in our dining room (see attached pics plus one of the kind of thing I am thinking). The main issue is it's an end of terrace wall which...

We have a problem with white mould on our rafters, which has been put down to poor ventilation. I am hoping for some advice on how to improve our situation ... This is a late 19th century terrace house with a London pitch or butterfly roof, which gives us two completely separate, shallow loft...

Hi guys! Our bathroom doesn't have windows, so we need to keep the light and fan on after every shower. Luckily we never take long showers. But even we are being careful, we have mould between tiles as you can see in the pictures. I tried with white vinegar and bicarbonate, it helped a bit but...

Hi. Indesit CA55NF Fridge Freezer bought 2012 has been in the same place ever since, apart from moving to decorate/replace flooring which last got moved probably 4 years ago. Today I noticed a small bit of water around the front leg when I opened the freezer door. I then looked underneath and...

I am unsure what caused the mould, could a blocked airvent with skirting board cause damp, which then cause mould? The airvent is very close to the ground, should it be at this level? Do these get flooded by rain, which can cause damp?
