condensation

I’ve been having issues with mould in the corner of my bedroom for the last few months with the walls being wet to touch but not sure if this is condensation or damp. The corner is on the external wall where my house joins the house next to us. As I thought this was maybe just condensation, a...

Hello We’re having issues with damp and mould in one of the bedrooms. It only happens in autumn / winter after heavy rain, and it seems to be the rain that’s blown horizontal by the wind. The mould only appears on the 2 exterior walls and furniture that is close to those walls (even if the...

We have a Bosch dishwasher which seems to be emitting steam or condensation from the top. It's delaminating our door units. I've taken out the door seal (3/4 of the door rubber thing) and cleaned thoroughly and it seems in good condition. Does anyone know what could the cause and preferably the...

Hi All - hoping someone can help diagnose please! We moved into an old semi-detached property 9 months ago which has an internal chimney stack with four pots. Two pots were capped (fully sealed) with lead, two caps had breathable plastic caps fitted. When we moved in, three of the four chimney...

Hi, Moved into a property 2 years ago and every winter we struggle with the walls by the window edge. It get’s cold, sounds hollow and as a result see’s condensation in the winter despite best efforts with dehumidifier etc. mould is also seen growing underneath in exposed patches. I’ve tried...

Can anyone help with their thoughts on this issue. noticed on Sunday morning a wet patch on the wall, presumed a leak in the roof (house about 20 years old). Roof valley/gulley did look like it was full of ‘stuff’ got a roofer out, had a good look at the gulley/valley and tiles either side...

My mum wants me to add a layer of insulation around the outside walls of her small bungalow and clad over it to improve her damp and unhealthy living conditions inside. However I want to understand the problem and make sure her idea is the solution. The existing external cladding is wood with a...

Hi, Wondering about filling the gap (builders silicone) between the top of the outside leaf of my cotswold stone brick cavity wall where it meets the roof. It is a 5 year old traditional new build (detached) House by the way. I want to prevent small birds, insects and other possible pests...

I am in the process of renovating a top floor flat, we have access to the loft, the previous owner had a small section of the north side of the loft boarded. I have been up and down for various tasks and previously noticed drops of water. I added 20 lap vents, 10 on each side of the roof. This...

BG: Old terraced house. Have had recurrent rising damp issues since moving in many moons ago. Bubbling walls, peeling paint, black mould etc. Replaced the timber in the living room coming up to a year ago. Two of them had collapsed beneath the floor boards. During this time we aired the entire...

Hi. I just had my roof re-felted and new battens. Breathable membrane, air ridge tiles and a vent tile. I've noticed that there seems to be a build up of moisture in the front of the roof, it appears to be running alongside a batten. Should I be concerned or is it simply condensation that is...

I've noticed this evening a lot of condensation in my living room, in the alcove closest to the window. Just wondering if a damp / mould paint would help with this or if there's something better that I could use to help? Thanks all!

Hi everyone, first timer posting here. I moved into a house (having been in a new build flat for 15 years) back in July. The house is an end of terrace 1908 (approx) build. When we got in, we discovered the insulation in the loft space was nearly non-existent so my partner set to improving the...

Hi all. I moved into a house built in 1990 and the main bedroom has a bay window with a ceiling lower than the main ceiling. Over the summer everything was fine but in these colder months the humidity in room won’t go below 68% and it causes loads of window condensation in the mornings. If I...

I'm actually in Sweden but I'm a brit so thought I'd try on this forum. We have an old (150 yr old) log cabin which I am renovating, currently insulating the upstairs. 2 x 4 stud walls with 100mm celotex between studs, VCL, then 50mm Celotex over studs. The walls are very uneven so there is a...

My daughter has an ex council house in Wiltshire which I am helping with refurbishment. There is a fairly old looking, 1970's perhaps, single skin prefabricated porch with a flat roof which has always had problems with condensation, especially on the ceiling. Not sure what it is made of, not...

We have a standard 1950’s constructed brick and tile semidetached house. The first floor bedrooms are all dormer style and constructed in timber frame with plasterboard (foil lined) fixed to inside and cladding to external face. I understand from our neighbour that the timber frame walls are...

Greetings, Over the past few years I have been working to insulate a mid terrace house built in the 1860's and I have reached the point I need to start installing some condensation vents. I have opted to go with the insulated 75mm Passyfier vents which require a 152mm hole. The walls are...

Hello everyone, I'm about to receive delivery of a Yardmaster metal shed and I've been reading about condensation issues with metal sheds in general. I spent a good deal of time prepping the base, concrete pavers on bed of type 1 aggregate and sand. What I didn't realise is that a DMP is also...
