Hi,

I’ve been having a re-occurring damp problem in one of the bedrooms in our house despite following advice given from a variety of sources but still notices signs of it. Right now, I’m kind of at a loss as to what to do next, what to do to prevent the root cause etc. so any advice would be very gratefully received.

So a brief bit of background – we bought our house about 2 years ago, and noticed the damp problem straight away. It is in the bedroom at the top of the wall (so not rising damp), it’s on an internal wall, though the wall is on our chimney. We have a wood-burning fire which was installed before we bought the house, so the chimney is in use.

When we bought the house, it seemed that the previous owner had some broken lead flashing around the top of the chimney which she hadn’t bothered fixing as she was selling the house. We had a roofer round who fixed this problem immediately, and we were advised by him and a plasterer I spoke to at the time, to strip bedroom wall to allow the wall to dry out. I spoke to two plasterers around this time, both advised that by leaving the wall to dry out, as long as I’d sorted the cause of the problem (which appeared to be the lead flashing) that the wall should be fine to plaster eventually as the brickwork will eventually dry due to the porous nature of the bricks. So I followed this advice, stripped the wall and left for 10 months for the wall to dry out.

In this time, I’ve used a de-humidifier to assist with drying the wall. I’ve also had the roofer back on an annual check of our roof – I’d asked him to double check the flashing and ensure there is no way water can be getting in, which he has done and assured me that there is no leak. After the 10 months, I had the room plastered and following that we painted a huge area around where the damp patch was with Damp Seal paint. Once dry this was followed by a mist coat and then painting the walls to finish the decorating.

This was about 4-5 months ago and just recently we’ve started to notice a few damp/cold spots re-appearing on the wall. There are only a few and these are quite small, a couple of cm’s in diameter. But this looks like early signs that the damp is re-appearing.

Having followed the advice of a number of people, I’m not quite sure where I’ve gone wrong – the root cause is apparently fixed, I’ve treated the walls as I’ve been advised to do but it’s still re-occurring. Have I been given some advice that is not quite correct somewhere along the line? Can anyone advise what I should do from here – can I fix this by adding any further treatment to the walls or is it a case of having to start again?

I’d really appreciate any advice you can offer as I’ve no idea where to go from here.

Many thanks.

Thank you for your reply, I've answered some of the questions below, if you have any advice it'd be very gratefully received.

The wall with the damp is against the chimney, the chimney runs through the centre of the house so is not an external wall. We have a contained log burning fire, so not an open fire. I've got someone coming to sweep the chimney in the next week or so and to check a few things as I'd read it's possible that the area might have moisture build-up or not be well ventilated.

I have been in the loft, but there is nothing obvious I can spot that relates to the condition of the walls below - there are no damp patches or leaks that are noticeable.

I've attached two photos of the wall, but the quality isn't the best as I've had to reduce the pixel size in order to attach here. The 2nd image is taken of the wall with the damp spots on the left hand side, not sure if you can see but there is a slight darker patch on the white ceiling as well. The 1st image is a close up of the damp spots.

but wheres the chimney breast on the wall? if you can canyou show it an the fire an the stack. in the loft did you look for condensation on the underside of the roof above the damp?
if its coming from the flues it will be chemicalsthat attract moisture.
