damp

I've been slowly renovating an old 1800s listed building which was suffering from a lot of damp. I've managed to combat a lot of the damp in the house by installing French drains, fixing gutters, reverting to Lime plaster but there's one room which is completely throwing me and not sure how to...

I have an old solid wall sandstone barn / cottage (approx. 150 - 200 years old), I am having the dining room plastered however there is rising damp on the external walls and around the fireplace. The old plaster is onto a cement rendered wall with bitumen damp proofing however this has failed...

Hello to everyone, I'm new here and ready for advice/a roasting. As you'll see from the photos, we have had two damp areas, and these have been present for the past two years. We have now had the bay repointed outside, and a few weeks after that, I coated the brickwork with Stormdry. I wonder...

Hello all, I would appreciate anyone’s thoughts on how to fix and prevent this issue: A 1950s house, internal walls behind skirting wet and plaster crumbling away. Perhaps the external paving slabs are too high and have compromised the damp course? But as the moisture has breached the...

Hi Folks, Just had horizontal damp proof course and tanking put in, and replastering in the back room of a ground floor flat (3 walls). On the back wall of the property the plaster looks like in the pics - the bit at the bottom isn’t quite as consistent as the rest. Could someone more...

Hi everyone, Bought a flat at the end of last year. After I repainted a wall below one of the windows the paint began to peel and over the last few weeks damp spots have started to show. It appears to be coming from below the window sill which might suggest it's coming from a crack on the...

Really appreciate any expert opinions on this please! Semi-detached house and this is the outside wall. I think the damp might be because the outside rendering needs replacing (but I’m no expert!) I can’t see any obvious problems with it, but it’s very old. The damp seems to be worse in...

Hi, hoping someone might recognise my issue! External extension completed around 18months ago. Parex render finish. We’ve had really heavy rain for a week or so and there is a damp patch above the bifolds. It seems to be larger the more it rains and fades when it dries out. There is a hairline...

Hi everyone, I’ve got damp patches on the ceiling in our loft conversion bedroom. I can’t see any signs of damp anywhere else apart from this particular area on the ceiling. The wall feels wet to the touch where it meets the ceiling. We’ve checked in the hatch area above the loft and can’t see...

Hi all, I live in a property built around 1910 that’s semi-detached. We’ve had a problem with damp on 2 of the internal walls. We had a damp proofing company come out who recommended that we take around 1m of the plaster off, drill holes and inject membrane into the walls and re-plaster. I mist...

Hi all, Had my house reskimmed and it’s been 3 weeks now. I want to get a mist coat on but there’s still patches of darker areas that at first I thought meant it was still wet- but as it’s been so long now and they don’t feel wet to the touch (plus I had my house surveyed for damp before...

I'm living in a new build (A rated) for just over 4 years. I've noticed for maybe the last year that damp patches have formed on the outer wall in the ensuite. All other rooms are fine. The first ones to appear were the two directly above the window, on flat horizontal part of the window...

So. 6 years ago they built a house next door to my mates granddad. He is end of terrace and the new house foundations lifted the ground level on that side of the house so the internal floor is now about 40cm below the outside ground level. The picture below shows the outside. Inside the house...

Hi, We have had this patch taken back to the brick, it’s been PVA’d twice with other treatments on this occasion. It’s not coming from outside, above or below. A company called Britainia have checked it out. It’s only ever that patch, nowhere else. Short of knocking the whole wall down any...

Hi, I have a damp solid brick gable end wall on an early 1900's semi that needs a re-render (ideally in lime). Located in Sutton, Surrey with pics in a previous thread (more available): https://www.plasterersforum.com/threads/re-render-advice-gable-wall-victorian-semi.86442/ Had a few...

Hi, We have noticed damp occurring in our 2 adjoining bedrooms upstairs on the same side of the wall. We noticed it back in September 2019 when we brought the house, but decided to leave it to see if it would disappear. Since the heavy rain appeared over the last couple of weeks, you can see...

Hi there, I'm just after some help/advice please. We have had a rear ground and first floor extension which has been fully rendered in K-Rend. When we get a lot of rain i'm seeing damp looking patches on the first floor external walls, at first i was thinking it was the window sill, but can see...

Hi all, I have had my wall replastered approximately 2 months ago and I have this patch that persists. I have kept the room well ventilated and have recently had the heating on to try and encourage the dark area to dry out (although it is not particularly damp). I have been told to gently...

Hello, I'm new to this forum so hopefully this is the most appropriate place for this thread! I'm looking to buy a top floor flat, my only concern is some dark marks on most of the walls (internal and external facing) and ceilings. The external facing walls seem to have marks that correspond to...

Hi all, I’m looking for opinions and advice as to what the issue I am experiencing is and a solution for it. Please see my attached photos; a section of the exterior wall under my bay window has what looks to me a damp patch (particularly worse when it rains, as it is today when these photos...

Hi all, Have had stained wallpaper for the best part of a year now and decided to take the wallpaper off to see what I'm dealing with underneath (see attached photos). What would you folks suggest? Fill the holes and make good or remove all of it and replaster? It is in a living room so...

Good evening, Last summer we bought a 1970s bungalow which we had fully surveyed & rising damp was not found in the property. No problems with drains were found. The pipes for the heating comes from above & not below the property. The vendor had previously had a chemical damp proof injected...

Hello everyone We’ve recently moved into a house in Brighton which is made of bungaroosh. It looks like the external render has been replaced with sand & cement. It’s likely that the external walls contain a slate damp-proof course. The internal walls are mostly gypsum plaster (although one of...

Hello Lime Plasterers! 3 years ago, we bought a flint cottage. The first job we did was repointing the whole external gable wall ( with sand and nhl 3.5 lime as we are only a couple of miles from the coast) as the mortar was cement-based instead of the original lime pointing. We stripped the...

Hello everyone, I was hoping for some advice please. I have a patch on the wall in my living room. On the other side of this wall is the kitchen. The patch on the wall doesn’t seem to be getting any bigger over a period of 10/11 months. However, it sometimes gets darker. The is a much smaller...

I am a landlord and my tenants experienced issues with damp on the inside of a bay window and it didn't seem like there was an issue with condensation or ventilation (as is usually the case). I noticed a crack where the bay window render meets the brickwork on the outside of the house and...

Hi This bay window in a Victorian built terraced house has been having a few damp issues. After investigating, removing the skirtings showed multi finish skim going right down to the floor, so I've started hacking that back given that it probably was wicking moisture up (there was green in...

So I fixed a small damp issue on a house of a friend where a wall had just been plastered over plaster and plaster to try and fix the issue which I’ve now solved! After 6 months The wall is now completely dry, all the bits of plaster are flaking off the wall and there is a pile of dust on the...

Hi - Recently I've noticed random damp patches on my 3 year old K render below a window and near frontdoor entrance. The damp markings seem to be worse when bad weather hits. When the weather is nicer the staining is still present I believe - less so maybe as the aspect is south facing so may...

Hey guys! I just registered on this forum and thought I give it a try as I am really struggling at the moment. I own an old cottage in Dorset which I’m renovating at the moment. The pre owners haven’t used the cottage for 30 years. So it has not been heated at all. every single wall is fine...

Hello, this is my first time posting in this site after using it for information regularly over the past year, so go easy on me. I am renovating a 1930s ex council property in South Wales. It’s built with cavity wall bricks and the walls inside are mainly black mortar, but in good enough...

Hi there, I've just bought a house (1930s ish) where there is evidence of previous damp, as plaster has failed in certain places (lower corners of the living room) and has either crumbled off the wall or bulging in certain places. I cant find any evidence of existing damp or water ingress...

Hi, Moved into new house in the summer. We have had a few issues as it is a very old house that was returned back in 2014. The latest issue is dots appearing on wall when the room is hot. My guess is condensation or maybe damp? Its a kitchen/living room. Quite small. When I went to check...

I live in the basement flat of a Victorian house that was converted back in the early 80's. During my two years here I've noticed damp issues with quite a few of the walls, where paint and other unidentified layers have come away from the walls. I'm wondering if these problems are mostly due to...

Hi everyone I've bought a load of standard boards and now decided I may want to insulate them with polystyrene, can this be done? Literally some spray glue and bosh... I only ask because I've already got the boards, and have a few cold spots and damp patches in the old plaster. Upstairs I've...

I have a damp problem on and around the bay window at the front of my house. I've had a damp survey done which has flagged high exterior ground levels - which I'm getting reduced - I'm also going to install three new air vents as all have been concreted closed. I've removed all of the interior...

Hi, i'm looking at damp proofing my flat myself after getting a professional quote, the company listed the following.. Bathroom 1) To apply anti-sulphate onto the brickwork. 2) To plaster the wall with sand and cement with SBR additive. 3) To apply 2 coats of tanking slurry with a 150mm lap...

Hoping for a little advice if possible. Our boiler sprung a leak and water trickled down through the floor and damaged our bathroom wall. Thought i had dealt with the damp and waited months before stripping the paint and replastering. However when i did replaster parts look wavy. Uping touching...

We have had a dpc solution provided in the same places twice and damp is now reappearing for the third time in the space of 15 years. The previous two times the work was guaranteed but the guarantees are worthless. I have found 5 local damp specialists. I have managed to get 3 to visit and...
