condensation

Hi. I recently noticed a drip down the side of my house. Not been here long so dont know if its an old problem. It seems the culprit is an external drainpipe (from the shower I think). There is a ring of what looks like moss which is sodden. As this has only just started to be an issue, I...

We have some salt and clear tide marks. Could this be penetrating damp?

Hi there First time using this forum so many thanks in advance for any help anyone can provide, it's very much appreciated! I'm in England - cold winters, warm summers. I have a new shed (installed December) which, for the last two days, has dripped onto the floor from the ceiling for five...

Hi, I have been slowly upgrading a converted loft in my victorian semi. A couple of years ago I replaced the insulation in the rafters with PIR board. 100mm in between the rafters, 25mm underneath the rafter. 50mm gap between insulation in the rafters and batten for ventilation. At the...

Hi, In the last year we moved into a 1960s semi detached. The house has a chimney stack which is no longer in use but, from what I can see, has no vents. Over winter, we had some issues with condensation, one of which was on the chimney stack itself (see pictures, darker discolouring due to a...

Hi, has anyone successfully done this please ? Ive got a serious dripping which seems to be from condensation. Ive found a couple of suggestions online, one is installing a mixer valve introducing some warmer water from the tank, could be expensive though ? another was to glue a yoga mat on...

Hi, wanted some advice on some condensation on our cold water pipes. Please bear with me on this. Just after xmas we noticed a mouse had been coming in through a small hole next to where the gas main comes in the house and through the cavity wall. I filled the outside wall with mortar and the...

Hi all I’m planning on turning the garage into a workshop and have noticed this winter (we only moved in last year) that the corrugated metal roof seems to gather a lot of condensation. It drips down, not torrentially, but I’d want to sort it out before I get the electricity put in obviously...

Hi there, grateful for any advice. Live in a top floor flat where the bathroom extractor is mounted in the ceiling, with a flue pipe extending vertically about 0.75m, topped with a mushroom clowl. The extractor runs when bathroom lights are on, and on timer after the bathroom lights are...

I’ve lived in my property for years and due to financial difficulties I haven’t managed to sought a carpet for my doorway/stairs! I know have carpet and laminate which I’m slowly working on fitting but my concern is; My front door leaves wet patches especially when the weather is really bad...

Hi. This last few months we've noticed a musty smell in the loft and pretty much all of the roof membrane (if that's what you call it) has little condensation drops on it. Not sure what is causing this as it's never happened for the previous 9 years but I will be double checking extractor...

Hello All. I need advice regarding my loft, specifically insulation under and around the cold water tank. There is a bit of a story to explain everything that has been going on with my loft leading up to this and for that I apologise in advance if it is a bit long winded. Early last year it...

Hi all I hope I am posting this in the right place! I have a small L shaped bathroom (ground floor) in a old building that has no wall cavity. I've had a damp inspection (two actually) which both concluded that the damp I'm getting around the toilet and on the wall next to it is not from the...

Hi all, Recently I have noticed condensation falling back down through the extractor fan in my ensuite bathroom so went into the loft space to check it out. I noticed the ducting was not insulated which I know I need to sort out from reading other forums on here but also noticed there appears...

Hi, I've got really bad condensation Al over my loft on the timber and felt. I've noticed there's some type of silver insulation stuffed in to the eaves, looks a bit like silver bubble wrap.. Won't this be blocking the soffit ventilation? Here's a video: Appreciate any advice, hoping to...

Hi, This is a small flat roof that joins to the house and main pitched roof. Some background info: It has never had any insulation between rafters and doesn't have insulation on top. Timber roof joists/rafters with timber furring. Then plywood and then torch on felt. We discovered the...

Hello, A few days ago I noticed what appears to be a leak in the bottom left of my velux window - see pic. It appears to be a damp patch, it’s slightly noticeable that it’s damp to the touch but it’s not wet wet. It seems to be mainly surface as it dried very quickly. We did have a lot of rain...
