condensation

Hello, We have a bungalow with a dormer roof which has vented soffits (image attached) in cold weather the soffits allow cold air into the roof so the edges of the ceiling are colder and moisture condenses on these cold areas which leads to mould (image attached). I have recently fitted a loft...

Hiya, thank you for reading this :-) The details are: the house is a 1987 build with: Red brick outer skin, Cavity (I don't have any more info about the cavity at the moment as all our stuff is in storage), Thermalite blocks, Thick plaster (12mm approx), And a skim coat of plaster. On top of...

The day after I stopped to "relax" for Xmas , our converted outhouse/office water pipe burst :confused: Thus, xmas was a chaos of ripping up the flooring and borrowing heaters and dehumidifers and running to and fro to the tip. The chipboard floor was sodden, and the mineral wool insulation...

Hi all, I'm looking for some opinions on the cause of some wet rafters in the attic. The rafters to the rear (north facing) elevation are all wet on top and down the sides. The rafters on the front (south facing) elevation look to be okay. I'm trying to work out if the likely cause is a roof...

Hi All, I'm looking for a bit of on advice. My house (1920's bungalow) is notoriously cold and had condensation issues. I've replace the floors due to wood worm(suspended floor, strip foundation) and insulated with rock wool as I went - this doesn't seem to have made a huge difference to...

As winter months have hit, our extractor fan has begun splurting out brown liquid. We have put this down to condensation. Unfortunately the duct runs up through the loft, and our loft space is fully insulated with no walking space, so we're not really able to insulate it. Also, it goes up...

Hi all End of terrace built in 1890. Since topping up my insulation, I have a significant build up of condensation on the breather membrane in my loft that I’m trying to fix through: - installing lap vents in between every rafter at the lowest point close to the eaves. - installing a...

Hi all 1890s terraced house, laid some new insulation in the front half of the house last year, didn’t get round to doing the back half. Just been up there to find loads of condensation at the front pictures attached, non at the back. What do I need to do fix please? Bathroom is at the back and...

We have recently moved into a house, we seem to be getting an issue with dampness on one of the outside walls of our bay window. the wall isn't always wet but it flares up, especially when it's cold outside. One minute it's wet and one minute it's dry. We have had a company that offers DPC look...

Just had my old single-pane timber sash windows replaced with new, double-glazed ones. I woke up to this amount of condensation, which is much better than the old crappy windows, but still, it can accumulate and build moisture etc. Is this right at the end of the day for new windows? Should I...

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...

Hello, Apologies for the long description, I guess being accurate is useful here. I am looking to find out if there is any benefit of installing a vapour barrier between a utility room and remaining living space of a small outbuilding, currently used as an office. There is a small partitioned...

Hi all. I've read conflicting things about how to do what I'd like to accomplish so thought I'd post my own question as everyone's circumstances are different so here goes. I live in an end-of-terrace circa 1906 property with cavity walls. Both internal and external walls are of red brick...

Hi all First post here. I've searched around everywhere for someone with a similar set up to my place and found nothing so had to ask for myself. I have a ground floor flat of a converted pub built circa 1905 and converted in the mid 90's. It's solid brick wall construction, single glazed...

Hi all We live in a semi detached Edwardian property with two large bay windows in the master bedroom and lounge. In the master, no matter what we do we seem to get excessive condensation each morning. We have tried a dehumidifier (didn’t work) so am at a bit of a loss to what we could do. We...

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...
