- If you wake up in the morning to find your windows misted up and a damp black patch on the ceiling or wall, (usually in the corners) then you need to sort it out before it does damage to the room. Using a dehumidifier is an expensive option that does not cure the root of the problem. Air flow is crucial.

Thanks for sharing I put one in my bedroom and it works brilliantly thanks
Thank you very much for this video. Exactly what I was looking for - damp corner in bedroom at ceiling point where the 2 outside walls meet. Just as shown in your video. Will be looking into options available to increase air flow - a vent to the outdoors in Eastern Canada may be a bit much (Maritimes, lots of snow and wind) but I'm pleased to see there's solutions. :)
What a beautiful view from your window.
I love your easy to understand explanations. Thank you. Keep up the good work!
You're very welcome!
Simplicity, and soo effective I take my hat off to you good sir
Thank you.
thanks,I have same issue fingers crossed mine clears up..great channel.. keep up the great work
Thanks Neil. Al.
Air vents are a must, especially in older houses.
True but in smaller properties they let drafts in , especially in the winter
Thanks for sharing. I blocked one of these up a few years ago from the inside of the bedroom and some damp has appeared. Will sort it in spring.
@Colonel Ga-Taffy Seagull noise!
No , problem you have is condensation not damp . Just control it by opening a window up for few minutes every day.
Wonderfully explained, easy and simple 👏
Thank you Mate 😊
No problem 👍
Thanks for making this video. I have an identical problem so I'll be giving this a go!:)
No problem.
Having air bricks done really work. Most houses have trickle vents fitted and they are the same principle and they dont stop the water residue on windows or mould in corners. Ive been looking for a solution for years and found out about the Drimaster positive input ventilation.
I have tried all the usual ways to prevent damp in our house and I was thinking of these units myself. Did you fit the unit yourself and how do you find these units?
Agree with all you have said, PPVs are the way to go, NuAir made in UK, they often come with small heat element. A lot depends on your loft, does it trap warm air, does it warm even in winter catching South direction
Best solution is run a dehumidifier through the daylight hrs , it will remove the dampness you will see just how much water it’s removed before you go to bed it will surprise you at least if pints in Six Hrs
If you notice in attics the insulation is not rolled to the eves this could also be causing the mould in top corner my advice would be to add insulation out as far as you can reach and just leave a 50mm gap in the attic at the eves for air flow
Hi, how would you recommend doing this on slanted ceiling?
I had a damp specialist show me that on a sloped ceiling that had mould growth that the reason there are vertical streaks is due to mould growing where there is no insulation, and the clean lines are where the roof joists are. And in bedroom the cold corner has no insulation in the eves hence mould growth.. he said you can add celotex insulation or wash down (I've used diluted bleach/mould cleaner works well) and add air brick or ventilation which should stop mould coming back.
Hi Al
Sometimes damp on or usually in a corner of a ceiling, particularly noticeable in the winter can be an indication of poor or no loft insulation. We also had the same problem and cured it after a builder mate gave the advice about the insulation. Most people will tend to open the window when taking a shower or when cooking for example, fine in the summer months, but in the winter this adds to the problem of drawing cold damp air from outside then mixing with the warm humid air. Over time, this can lead to the problem of mould and mildew on ceilings. I hope the north wind doesn't decide to blow through your new vent on a cold winters night and blast you right in the khyber pass lol :-)
Thanks for the info Cliff. Al.
Sort of right. Cold damp air from outside will still hold less moisture than warm humid air inside the home. It's nearly always worthwhile opening windows, if nothing else you get fresh air into your home. Indoor air is incredibly polluted just by the materials in our home and lifestyles. Basically if it isn't raining the air outside will normally be dryer than the air inside, and certainly healthier. Heat also helps, keeping your rooms at a sensible temperature will help prevent mould when combined with good ventilation.
Yup that's cold bridge. Vent help with condensation, but why make all cold and unefficient. Window with vents will be sufficient
@@stefanoliwa625 we have window vents but our back bedroom suffers every winter with mould on the ceilings in the corner right near the window and directly above the window Absolutely fine in the summer and that and the bathroom which is next to that bedroom suffers to with mould but I put that down to showering.
I noticed the room had UPVC windows fitted, these are probably an retro fit. The problem with them is that they help to seal up the room from draughts that may have there with older wooden frames. These day the better UPVC windows come fitted with "trickle vents" which stop the condensation problems. They can be retro fitted to the UPVC window and don't cost much money.
Thanks for the info.
Great job! Too many people assume heating is the answer. Funnily enough, there's a blocked up vent in my bedroom (which will feature briefly in my next video).
Olly Parry-Jones Keep up the good work, will look forward to your video. Al.
Thanks for subscribing, by the way.
Thanks for this video . I searched for a long time for instructions how to fit a hit and miss vent.
No problem!
Don't suppose you could do a video fitting an air brick outside could you? I have a damp issue in the corner of a bedroom, looked outside and there is no vent at all, so looks I will need to add one from scratch. Many thanks.
Such a lovely man, thank you for these wonderful videos. Much appreciated.
ngatiramona your more than welcome
Really lovely man. Simple and easy explanation. It works great.
Thanks Edmond.
Hi Al, once again, a very concise video. I'm currently converting a single skin brick garden workshop into a small photography studio. I've removed the ceiling to open up the roof space for extra height. It's now insulated with 50mm Kingspan. The internal walls are framed and insulated too. Upon checking it, the surface of the uppermost part of the Kingspan lining the roof has collected condensation. Should I be fitting these vents either side of the building (one high, one low) to allow air flow. I'm in central Scotland where its damp outside most of the time so I'm not too keen on introducing it to the inside of the building.
Your advice would be very valuable to my progress with the project.
Cheers
Hi Peggy, I do not think in your circumstances vents would be a good idea.A small dehumidifier might be a better option.
Great vid. I live in a house with cobbed walls so impractical to make a vent. Would putting a vent in the ceiling directly under the attic be a alternative?
Yes better than nothing.
Thankyou
Good video. I actually did this in my garden shed, which was dripping with condensation - the problem pretty much immediately went away (I still however air the shed out regularly, on clear/dry days, which helps too.
Thanks for sharing
very good tip
The jobs are so well explained, make you want try thr job yourself. Thank you and I will be subscribing to your channel. Thank you, a very likeable man.
Thanks for the sub!
Yes more ventilation helps, although in bedrooms or any room black mould is condensation not damp. Damp is as a result of damp course breaking down and it will travel only 3 feet. Cant reach the bedrooms. I find it is a matter of planning when one wakes up in the morning open the bedroom window and shut the door on leaving, after breakfast shut the window. If a wet patch does appear on the bedroom wall and it is not black check for leak in the loft or roof etc.
Thanks for the info.
You get an immediate like for reminding me about spiders. NO to creepy crawlies
Ha ha , don`t you just love them.
Great video!! Thanks!
Very well explained, this should sort out my damp north facing walls. Will look into getting these fitted, thanks buddy 👍
No problem 👍
@@dereton33 hello mate I have damp on a wall bow window level and just above floor level.. could you put a vent at that level? Its side wall as victorian
Thank you for this video. Most helpful.
You're very welcome!
Wow I enjoyed watching this and your practical approach....!
Thank you.
Thanks. No problem
Great vid, very helpful!
Thanks Lee.
Hi Al great video, any ideas to prevent damp, condensation and mould in our ground floor maisonette? Thanks
A dehumidifier.
Hi thanks for the tip. Would you do this if the damp was at the bottom of the wall and if wall is wet?
Yes, absolutely
Thank you. You're a life saver.
No problem!
Judging by the thumbnail I thought my man was fitting the worlds smallest radiator!
Now there`s an idea.
Hi buddy love your videos in our spare room there IS a very already however still got moisture in the corners (upper) and in.particular bottom corner x1m currently painting the room.out and the bottom in particular where moisture has wet paint as such I'm assuming I have a separate issue? The chimney is the opposite side to this semi detached
Thanks
Either knock a vent through or use a humidifier.
Great video. I use a dehumidifier. I bought one from screwfix. In the winter I put it in the hallway and run it for 4-5 hours at night before I go to bed leaving the bedroom doors open when it's on. It gathers 500ml of water in that time. I get next to no condensation on my windows in the morning now. The one I bought also has a clothes drying function and only costs about 2p an hour to run.
Thanks for sharing
Hi, any chance you could tell me the model you bought, I'm after getting one for my damp issue. Cheers
What make mate?
Which one did you get?
Great informative videos, perfect!
Glad you like them!
That looks a nice area Al . How much are those houses to buy ? .
How come i have rising damp on internal walls of the old part of my house? extension on back to kitchen is fine. Solid floors put in some time ago in place of timber, re-plasterd dashed on outside looks like its even passed its life span, marble chips white background going black with dirt, original air bricks plastered over! why they did this I will never know but its maybe because they thought as the timber floors were taken out and replaced with solid that it would be ok,?
old part wasnt protected the same way the extension was. you will need to retrofit dry lining
What a lad! thank you
No problem.
Thanks for advice....great
No problem.
i have a built in wardrobe with plasterboard walls. for air flow can i make two holes and put vent covers on? does one need to be high and one low? also what way should the vents face. thank you in advance
Yes two vents one high and one low for circulation. Vents facing down.
Thank you so much, it’s amazing video and for sure it helps a lot. Love you
Glad it helped!
Thanks, I really learnt something there. Extremely useful. :-)
Glad it was helpful!
Hi thank you for sharing your knowledge, do you know if there is a lot of damp like this on the walls of the bottom flat (as in on the top of walls and ceiling), will it affect the flat above if the resident in the bottom flat doesn't do anything to fix the damp issue ?
It could spread up to the above flat.
@@dereton33 okay thanks
What you need are air changes per hour, cold as it may be you need rid of stale humid air and need to keep the fabric of the building warm, a juggling act, an interior fan running or windows permanently open front and back for cross flow ventilation.
Thanks.
Very useful.Thank you
No problem
Thanks for the tips. But it is so difficult to avoid mould when you live in a small flat. we only have a small vent on top of the double glaze window within the window frame. the sliding one. The mould has stained the corner of the roof. I guess we just need to treat it and do the painting.
I have the exact same issue , live in a small flat, those " tickle vents " on the windows don't really do much at all barely even prevent condensation on the glass let alone preventing any damp/mould , I painted over mine with ronseal damp paint first , you might wanna look at getting a portable dehumidifier to put on your window ledge you can pick them up for about £30 on amazon / ebay and help a lot in small rooms , best of luck :)
Buy a dehumidifier from screwfix. 👍
A dehumidifier is your best option by far. Also buy some cheap humidity meters from Amazon and put one in each room. You need to keep relative humidity below 60%
Hi dereton33, thanks for the video. What if there is no existing vent to unblock... do I need to add something to the outside? If I just drill the holes through the wall, then I've got an unsightly mess on the outside of the wall? And possibly water ingress? Thanks in advance for any advice.
You can get a vent kit which comes with a pipe to link the vents inside and out.
@@dereton33 thanks for the reply! :)
thnak-you i will try this my sons bedroom ceiling all black hes on two outside walls as we live in bungalow its getting worse
Worked for us.
Just moved into our property, and the previous owner "cleverly" did something similar and covered the holes with a slat of wood from the inside. 🤦🏻♀️ Thank you for your video!
It happens all the time.
@@dereton33 went to bnq after watching. Installing it now. 😁
I expect this solution depends on whether the property has had cavity wall insulation installed. If so, this would be the reason for having had the outside vent blocked up. And, in which case, any cold patch on the internal side of an outside wall (on which condensation and then mould is forming) could mean there's a thermal bridge across the cavity at that point, possibly meaning either the cavity wall has failed there and/or something is conducting the heat from the warmer inner wall of the cavity wall to the outer cooler wall (as I understand it).
Thanks for the info Martin.
Good video. Cracking view!
Thanks Luke.
Top man as always.
Thanks Ryan.
Hi, can you tell me how you fixed the discoloured part of the wall? Did you just paint over it? Thanks in advance! :)
Yes I painted over it.
@@dereton33 of course kill and treat the mould first, bleach wash the wall, smooth out any bubbles, flakey paint once dry and repaint.
Hi there, we need to do exactly this but my wife is worried they were blocked up for the cavity wall insulation. Do you have any advice on how to handle this?
There is a vent tube you can get to pass through the wall.
Any tips on temp sealing an extractor fan during the winter ?
Sorry no.
Thank you for reply to this video still. I have a vent outside with bricks missing and then plasterboard on the wall inside. I have fitted a vent inside just like the one in the video bu the wall is still damp. Any ideas ?
See if you can fit another vent on the opposite wall to cause a changing airflow.
@@dereton33 thank you I will look into that
I have a timber framed house, some years ago I came into a bit of money and had all the windows replaced with triple glazing there were no vents built in the house was built in 2003 and I live on the NE coast of Ireland, there has been black sooty mould growing on the window frame and walls the interior pane gets fogged in the morning.
Regards
Ventilation or a humidifier.
@@dereton33 Dehumidifier lol
Would the same sort of procedure apply to putting a vent in a covered up chimney breast, specifically in upstairs bedrooms?
As long as the chimney is not blocked off on the roof .
Great, thanks Al, appreciated!
Great vid like the way you came across
Thanks William T
Thank you. Great post.
No problem.
simply because houses sweat if you dont introduce fresh air , water (air moisture) turns grows spaws and before you know it damp conditions, ideal high and low level vents combined are the best. trickle vents were removed in double glazing which was the worse thing they ever did
Thanks for the info Paul.
Looks like a black mould problem as well!
Hi Al. You are correct in that using a dehumidifier does not cure the root of the problem but many people could find it hard to solve the root of the problem. These may include tenants with an indebited landlord etc. If this is the case then I suggest they try a moisture absorber first as these only cost the price of purchase (ie no running costs). If these are ineffective then a full size dehumidifier will definitely do the job and units like the Meaco 20L Energy Efficient dehumidifier only use 255w so that's not too bad.You can also purchase dehumidifier with an energy saving funtion and these units either automatically turn off or run in fan only mode once the set relative humidity level has been reached. Therefore running costs will be lower than other comparable dehumidifiers without this feature. Nice video (again) btw. :-) Just to add that landlords can write of a dehumidifier as an expense so if you are a tenant pproach your landlord first if you want to buy a dehumidifier and see what they say.
+ByeMould . Thanks for the info.
+dereton33 That previous statement was not really true. Most mould problems are caused by occupier lifestyle not construction issues. Landlords should not have to bear the cost for damage caused by a tenant. In most cases mould is caused by failure of the tenant to ventilate and heat properly. I have had tenants cause hundreds of pounds worth of damage by turning off bathroom extractors, drying laundry indoors on racks as they said the dryer was too expensive, and not heating the place properly (again they said it was too expensive) I had to completely redecorate once I gave them their notice. New tenants are brilliant, and guess what, no problems with mould. I now have black mould listed as chargeable damage in my tenancy agreements. People are too quick to blame landlords. Unless there is obviously a leak (water staining) along with the mould, and it is confined to one area, look at your lifestyle first!
+Spencer Wilton I am a landlord too and have had the same experience as you. One tenant was terrible for mould in one apartment whereas I've had no mould/damp issue with anyone else in the same apartment. However many properties were thrown up quickly during the last housing boom using inexpensive or rather inferior products in order to maximise profit. Once the 10 year guarantee is up then the property starts falling down. So I would say yes some damp problems are caused by construction issues. The fact that the UK average humidity level is over 65% (which is when mould begins to grow) does not help matters either. I do agree that when tenants dry clothes indoors, block vents, don't open windows etc then it's their own fault if they get mould and the landlord should not be liable.
BTW Al. I've subscribed to your excellent channel. :-)
Thanks very much.
Surely there has to be a better solution to ventilation than having gaping holes in the wall. I'm in a council flat atm and the cold air just pours through the 'vent' making heating the property almost impossible when the winter sets in.
Try a humidifier.
@@dereton33 i think he means de-humidifier

Just looking at the outside vent, has it been put in upside down, surely water could run down the vanes and inside?
There is a massive overhang outside so no chance. Was fitted like that when the house was built in 1968.
I live in a 1930's house so the bedrooms have chimney breasts although the fire places have been removed & filled in, can these vents be fitted to them instead of the outside walls?, & if so is it low down or near to the ceiling?.
Yes fit near the ceiling
Landlord put vent in corner of room for same reasons but it made the wall and room colder and didn't stop the problem. I painted with primer then gloss paint which stopped mould. If the walls were made of inferior materials then this can cause mould. Always check if walls are made of asbestos cement b4 u drill or cut outs for vents, air blowing through asbestos walls will blow asbestos particles into your home and then you'll breathe it in.
This is awful advice
Hi Al, I seem to have a very smelly loft and it seems damp. Could it be that after fitting very good and insulated loft hatch I created the problem? I have a lot of stuff in the loft and it all stinks. Getting dehumidifier in Screwfix tomorrow. Could there also be a small leak from the roof? But I have the water tanks and central heating tank there too. Bit baffled! 🤔
Do check for roof leaks but I thing you could probably do with a couple of vented ridge tiles.
@@dereton33, Thanks Al, I have bought a dehumidifier and ozone www.amazon.co.uk/gp/product/B076GZ26ZF/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 to get rid of the smell. It seems it's not that bad but I also found this czcams.com/video/vDWzITdEt5o/video.html Seems a simple and easy solution. Will be checking for loose tiles on the roof too.
@noxxi knox , thank you! I have bought these www.amazon.co.uk/gp/product/B01BLCI14C/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 The house is 1907 Victorian. In 2018 unless the roof is vented there will be a problem. I think I caught it just in time 😉 👍
@noxxi knox, thanks for that. The roof has a black felt, not a membrane. I will check out your links👍👍👍
Hi, did you manage to fix this problem? Things in my loft smell too. When the suitcases come down for holidays they smell musty and have white mould on them.
Can you put an air brick on the exterior side and drill through the holes to line up with the air brick?
Yes .
Should have turned the outside vent round the right way. That's going to cause ingress that way up.
I got an enviro vent system in to cure my issues. It worked great cured it all but it was expensive.
It simple, condensation is caused by two things: moisture in the air and cold surfaces.
If you eradicate one or the other or both you shouldn’t get a problem.
Jam, if you put heating on in the room, you'll automatically warm surfaces up.
Is it an older home I live in Canada and I live in a home that was built in the 60s and was told there is not a vapor barrier in the walls we gutted the bedroom and installed the vapor barrier and havent had a problem since, that's if you want to go to that extreme, we did have a major mould problem.
too much moisture, all homes have moisture, but its too much moisture, so cut down the moisture from cooking, bathrooms, drying clothes in doors (air rack etc). 6 heating will warm the air, dry out the moisture, but its still there, once you turn off the heating, the air cools and releases the moisture, so ventilation or a dehumidifier is need to blow or suck out the moisture.. until then, buy a hand held glass cleaner, you can buy easy, and every morning, do the windows, walls if damp, shower glass, especially after use.. also, long socks filled with cat litter is a cheap way of sucking up moisture, once it goes hard, chuck away old cat litter, refill, replace at damp points, window ledges etc..
What do I do if there is no vent in the room? I mean I have a vent for warm air, but I don't have a vent that leads outside, I don't know how else to increase the air flow in my bedroom. It's also in the basement, and there's no particular corner that's damp, it's just very humid. It's like walking into a room full of soup, the rest of the house is far less humid.
You could run a flexi vent through the ceiling and out of room above.
I get quite few damp patches upstairs walls will it help if I do same process ??
Yes .
Is there updated video of the damp issue solved?
No I have been meaning to do one though.
Is that an old house with cement render on.? As if so this is exactly why that has condensation problems
No.
Can I just drill some holes all the way through and then fit the internal plate ?? I don't have an existing vent on the outside
Yes if you want.
Fairplay on your video will help with air circulation and some condensation but the reason condensation is happening is because heat is meeting cold the window seals are broken if they are double glazed thats why the windows are like that and the walls are not insulated properly. Ive seen huge amounts of insulation put in houses then a big hole put in the walls pointless having insulation then. Ps the only vents suitable for insulated houses are automatic or extraction. Local council houses seem to be the only ones that have damp problems because the council will not pay to fix them properly.
I'm facing this issue at the moment water leakage through the seal and council saying it is condensation my bedding, clothing also feel damp... Total hell mate

ben lockhurst
The dehumidifiers should solve your problem mate. Get a low power version!
There lies your problem, insulating the walls actually traps condensation which then has nowhere to escape. Check out this site it helped me alot www.heritage-house.org/damp-and-condensation/managing-damp-in-old-buildings.html
Close the window you moron
Bit late perhaps to save you mr Ben, but google weather conditions in your town - if the humidity is above 60% then there's really no point in opening your windows, it will just make it worse, you are essentially forcing wet air inside.
Buy a small electric dehumidifier, the ones from poundland do nothing really.
The amount of water those will absorb is absolutely nothing in a room where you need to remove water from the air. Our Bedroom ALWAYS rises up to 80% humidity (and causes all kinds of problems), but we run a dehumidifier 24/7 to keep it around 40-50% and our problems have gone away.
I'm going to fit in 2 rooms. Thanks for that
No problem 👍
Our flat had a fireplace in the bedroom long before we moved in. The room feels cold and damp, more than the rest of the flat if the door is kept shut. Should there have been a vent put in where the fireplace was. Do you think this would make any difference? Thanks.
Certainly would cut a hole for a vent you can use one with a slide to open and shut it.

A useful video explaining a simple fix but never refer to mould as being caused by damp, it is caused by condensation.
Ok, thanks. Give me a slap on the wrist.
@@dereton33 Hey, sorry if I offended you, it wasn't meant that way. Mould is often misdiagnosed as being caused by damp so people do not consider their living habits which are more often the cause.
@@raydavison2972 well said! I would even take this video down as other people have comments on what is wrong.
You don’t need a vent , simply open a window in the morning for 5-10 minutes or buy a new window with treacle vent . It’s misleading. And the point you’re making as well is condensation created by the occupants. If it’s damp it’s would be running down the wall and yellow and brown stains . Obviously not as you can see .
All condensation is damp but not all damp is condensation. Giving somebody a slap on the wrist for something that you understood very well is a thing on its own. I leave that up to you.
What’s the difference between damp and condensation?
Thank
No problem.
Did that vent fix the condensation on the windows?
Yes sorted.
Does using dehumifers kill mold or stop new mold appearing I have mold in my bedroom and I use dehumifers also is salt effective and ok to use in dehumifers that have crystals in the top of dehumifer when Crystal's have run out I wanna save money and not have to keep buying more dehumifers when Crystal's have run out
They do help in drying the air out.
