condensation

Hi. Hope you are all well. Got a problem and can’t stop thinking about it, so would like to pick your brains! I’m laying tiles in bathroom which is just above ginnel. Before overboarding realised the whole thing is uninsulated so air from outside can easily make its way straight under the...

I'll try keep it as brief as possible as I could go on on.. I'm having an internal damp issue on the front internal wall (north facing). See pictures of internal and external. House built in 1875. Yorkshire stone build. Damp ONLY occurs in winter, coincidentally when turning the heating on...

We moved to a 1950s detached house in September which has a cupboard space under the stairs. I've noticed some quite heavy condensation inside it which you can see in the attached pictures. The cupboard does smell faintly damp and there was a lot of mould / blown plaster on the walls here before...

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 have read lots of threads about damp but find that no two issues are the same. My problem is on an internal wall, that is a "peninsula" wall rather than a wall on the perimeter. There are a combination of damp patches, a damp patch from the skirting and bubbling lining paper. I think...

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'm looking for some advice related to an issue with our loft if that's ok. Our house is around 300 years old with the original stone roof (not listed). It has two loft cavities with an exterior wall running through the centre of the house. Since moving in 3 years ago we have done...

First time poster here. My apartment windows have obvious signs of deterioration, water stain and wall peeling off. I'm very convinced it's a water ingress issue as it's prevalent in the whole building, especially the way the stain looks suggests to me it's from the structure side, not the...

Hi all, We're battling serious water damage on the second-floor front wall of our Victorian semi (pic 1). There are no visible issues on the exterior. The previous owners advised that it was caused by an unresolved roof leak. They finally got the front re-roofed but didn't repair the damage...

The UPVC windows in my house are showing signs of condensation and this is darkening the net curtains . Can this possibly be repaired or what can be done to correct this. Thank you

Evening all, Firstly, Happy New Year! I’m planning on insulating underneath the floor boards in my living room. 1900s terraced house so adequate crawl space to do from below, plus I don’t want to damage the floor by lifting up. From research I understand best practice is a vapour barrier...

I had an issue while I had some of the insulation up it wasn't all sealed in for a week and caused condensation to form on decking, dried this off as best as I could and then sealed the pir foam (50mm) in place, foamed all gaps and taped it. Now move on around 2 weeks I decided to take one panel...

Hi all I'm having the insulation in my loft removed and redone (due to mice) and as I wan't to keep the boards on the joits (and keep a cold loft) have been offered the option to have 5cm rockwool pushed up against the ceiling plasterboard, plus a foil quilt (e.g. the YBS superquilt) draped...

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...

Hi, iv recently bought a vent axia piv unit. Iv noticed there is a space on the unit where a plug goes possibly for controls. The problem is I cant find any controls for it online, I wondered if there was anyone who could point me in the right direction, or if its not for a controller then...

Hello, Please see attached image. Recently I've start to see damp/condensation in the corner of ground floor living room. It's around 100 yrs old house. Walls are brick walls. It doesn't seem to be anything obvious from outside though. Touching walls around damp area seem to be wet a bit...

My wife and I have moved into a 60's fixer upper which has barely been touched in 30+ years. With the cold setting in, our porch is starting to develop a lot of condensation and damp (photos are from when we moved in). It's UPVC with no insulation and there's just a very thin stud wall with a...

Hi, I moved in a a rented flat in a newly constructed building 2 weeks ago. There is a laminate flooring in the flat. In the utility room, there is an interrupter that reads "Extraction". This interrupted was set to off and the landlord didn't mention it when I moved in, I didn't even know it...

Hi We are wanting to buy a property which just came back with a level 3 for damp in the home buyers report. The property is a Victorian terrace with solid floors. There was minor evidence of damp when we viewed but we thought it was just condensation and ventilation issues as the property is...

Hi All! First time post but have been a long time reader of the forum. I bought my first property in 2020 which is a 1970's maisonette which includes a single garage which is one of the middle garages in a row of 4. Last winter and whenever there is heavy rainfall the garage becomes damp as...
