condensation

Hi there, We moved into our new house last winter and noticed water on the ceiling of a small extension to our kitchen. At first, we thought the roof was leaking, so we replaced the felt roof. However, we now realize it's due to condensation. I want to fix this before winter, but I'm unsure of...

Hi, Has anybody done a steel portal framed shed with timber purlins/sheeting rails and clad the outside with 40mm or so of PIR insulation then just fixed single skin steel sheets right onto the PIR with longer fixings? No extra plywood/OSB, battens or breathable membrane? Planwell seem to...

Hi everyone – I'm looking for some advice on our 1910 solid brick wall terraced house in the UK which we are planning to renovate. Unusually, it has some prefabricated 105mm thick concrete dormers and I'm not sure how best to renovate them. We are in a conservation zone, so have no choice but...

Hi. I'm looking for some advice on some internal air vents that I have. It's an old house (1900/1910) and has a couple of big bay windows. The pictures show 1 example where I seem to get a lot of condensation. On this example, there is an existing external air brick fitted. Internally, the...

This is a 100+ years old Victoria house and I did a total renovation of the house + side extension in the kitchen. The problem is, we got condensation issue on the ground floor in the kitchen after side extension. We have been battling on this issue for 1+ year. At the beginning, we add a...

Hi there I'm planning to install a PIV system, but since we have a loft conversion, installation on a landing is not physically possible (the loft conversion is over the first floor landing, and access above the second floor landing virtually impossible (and the landing itself is less than 1m2...

Moved in 2 years ago, and had condensation issues in winter, in the rooms with external walls (rooms which have the the four corners of the house). Would an air vent fix this issue, also I was thinking of a hit and miss vent in each of the rooms, but fitting an air brick would be difficult to do...

Hi all, Looking for some advice on this as it's frustrating to say the least! North facing bedroom. House is a 1950's built semi. Been here 15 years. No major issues with damp in that bedroom during this time apart from tiny (and I mean tiny) mould spots appearing over the coldest of...

Hi all, First off - I've read the pinned condensation in loft thread and I reckon that answers my condensation / insulation related questions but have 3 Qs for those more experienced than me! I live in a Victorian terrace and I'm getting issues with condensation damp on my bedroom ceiling and...

When it's very cold, moisture drips from the felt under the tiles of the roof. It could be up to 50 years old (70's house) so it will not be breathable. No issues whatsoever during the heaviest rainfall. Currently, there does not seem to be any source of fresh air (no eaves providing this) so...

Hi all, We live in a 1930s semi, we have an old chimney flue outside (old cooking flue?). A this time of year we always get condensation on the inside bedroom 3 wall, definitely not damp as it dries out very quickly with a window being open (difference inside to outside temps). We've had the...

I've had my loft insulated and boarded recently to turn into a loft room. It's only been 5 months and I now have this brown sticky substance coming out but only in one place. I've cut a hole in the new boarding to see what's going on but it feels quite dry. We have a newish roof without any...

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...

Long story short, we have: 1950s house Double glazing, only about 10 years old, good condition. No condensation between the panes. Trickle vents OR openers that we leave open a crack during the night Two adults in the house, no pets High outdoor humidity (it was 91% RH last night!) and humidity...

Hi all, Thanks in advance for helping. Basically, as can see from photos, we have damp patches on our chimney stack. It's out of use and tops have been capped few years back (before our time). You'll see from photos damp is in 2 rooms, that are back to back, and share the chimney stack. 1 of...

Hope this is the right forum category for this, apologies if not. Long story short... we had a shelving unit pushed up against a wall in the living room of the house, it's been there between one and two years. Moved it away recently and found a damp patch on the carpet around 1.5 ft long by 1...

Hello all, I am hoping somebody might be able to help with an ongoing issue we have under our upstairs bay window. The house is a detached 1930s house. We renovated it around 6 years ago now, and this problem only seems to have arisen in the last 3 ish. Under the bay, we have a number of...

I know there are a lot of threads on here regarding loft condensation - I've already read many of them - but despite improving the ventilation I still encountered problems last winter. The property is a late 80s detached house. A few years back I replaced much of the original loft insulation...

Hello, today I've seen some patches on plasterboards and it was getting wet without any leakage. Upon further investigation, condensation on steel beems were seen.. before plastering it over, please can someone recommend what it needs to be done? (Appreciate if you can give me a name or link to...

Hi, I'm not sure if this is in the right place but, i stripped my kitchen/dinning room back to brick when we moved in and the linel condensates to the point were its dripping down the window. There was foam behind the lintel/under the cavity tray(if that's what it's called) but it's all fell to...
