- This video shows how to fit an external wall vent, these are often used for extractor fans, tumble driers or even just straight through vents as in this demonstration to ventilate a loft space. By using silicone or grab adhesive to hold the vent in position it removes the need to drill any fixing holes which can be very dangerous from a ladder. The hole for the vent was cut from the inside using a diamond core drill- • How to use a diamond c...
If you are installing a vent low down to the ground then drilling a few holes is not a problem, but when its high up you are much safer if you can remove the need to drill from a ladder. Silicone sealant or grab adhesive can be used to hold the vent in position.
This is an old video which I have missed uploading! I’m still very busy on site at the moment and could be for the next few weeks!
I often use this technique when installing external vents at height as it saves you from drilling from the ladder.
Happy Sunday people ;-)
Top tip from a top man. Been doing it for years myself. Absolutely no need to be drilling and fixing flimsy external vents.
Thanks for the comment ;-)
short. sweet. and to the point. No fluff. Wish they were all like that. good job
Thanks for the comment 👍
Great video, as usual. Thanks for posting them. One other good reason not to drill it - in most cases a hammer drill will break the brickwork when drilling so close to the hole. And if that diesn't do it, the pressure from the plug and screw will.
Absolutely.
Thanks for the comment ;-)
Great tip about not trying to screw the vent to the wall.
Have a great Sunday yourself Chez!
Thanks John ;-)
I've been watching your videos for a long time and before I started working I'd watch your videos to boost my confidence in my work and to learn new techniques. Keep up the work and the videos.
Great vid as usual....Son bought me a ladder standoff..worth its weight in gold for this type of job...stay safe..
Thanks, yes standoffs are good. I do use mine most of the time but on this occasion it was fixed to my other set of ladders.
Thanks for the comment
I was always told never to work on things above your head when working off a ladder. You may have been better moving your ladder to one side slightly, extending the ladder a little bit and working to one side. That way you are not looking up at what you are doing and less likely to overbalance backwards. Health and safety is paramount when working off ladders.
That's correct. However in this video I could not move the ladder to the left as the extension overhang was in the way and I could not move the ladder to the right as I was filming it. Good advice though ;-)
Thanks for the comment
Basically a 6 inch hole in the wall and nothing to stop the cold wind blowing in and insects, they installed one in my newbuild, and I asked them to put a non return air vent.
The one I fitted was to ventilate the roof space, because of condensation. I believe it had an integral insect screen. You can still fit these this way, and on the inside of the property, you can attach it to an extractor fan/hood.
In some properties they install vents like this, if there is a fire/smoke prevention system installed (I have a friend with a flat and she has a couple of vents like this, which are not good, as you can hear all the road traffic and it blows a gale through them) 👍
Good advice. Unfortunately being a plumber I end up on ladders drilling big holes for pooh pipes. I don't like to core drill from inside out as you can have too big a break out, and less mess to clean up in a household!
I'm glad I don't have to core drill from a ladder, please be very careful or invest in an alloy tower!
I do know an electrician that fell from a ladder and died.
Thanks for the comment ;-)
Appreciate the concern mate, not keen on ladders either but sometimes when your in the moment and need to get a job done you really forget about H&S and we really shouldn't. Getting older I'm also getting wiser... Send the boy up now. Just kidding :)
Another handy video. Your making me into a DIY master.....
Good stuff, thanks for the comment ;-)
It is often a lot less messy to core thru carefully from the outside after piloting thru inside out. Fortunately, I always place a couple of eye bolts or pegs above my top ladder stance and clip in to a harness. I also clip the ladder in too. If you are not familiar with rope access and self rescue or don't have the kit, then doing any kind of work at height with any power tools can be a serious proposition, not least a good quality core drill with top notch clutch! You would not want to become a prime candudate for gold medal in The Darwin Awards! I always prefer to put a bathroom extractor in the ceiling and duct out thru a gable if possible.
Thanks for the comment
Great so how do I take it apart with all that silicone on there?
You should be able to twist it to separate the components, then remove any silicone using WD-40 or silicone remover 👍
Hello im wanting to put an air vent in my living room i have one in the bricked up chimney breast at the base now does it really matter where i put an air vent on the outer walls either next to my bay window where the vent will be more or less opposite the chimney vent or can it be put on the back wall of the living room but do i put the vent down near the skirting board or mid height or near the ceiling .
But if you don't want to drill off the ladder. How did you do the core drill from the inside without blowing the face of your bricks off? Great tip none the less
Core drills do not use hammer action so it's very uncommon to blow the face from the bricks.
Thanks for the comment
+Ultimate Handyman ton of knowledge you have :)
Thanks for the comment ;-)
Where did you get this combination of products? Neither the builders merchants, plumbers merchants or electrical suppliers seem to stock these, only an interior vent, nothing with a collar on the back like what you've got. Cheers
I think I got mine from Screwfix.
There is one here with a flexible duct- www.screwfix.com/p/manrose-extractor-fan-wall-fixing-kit/11784
Or one with a telescopic liner here- www.screwfix.com/p/vent-axia-extractor-fan-wall-fixing-kit-100mm/86108
@@ultimatehandyman cheers 👍👍
@@ultimatehandyman thanks I was looking for the one with the collar.
I had to remove the previous vent which was siliconed into place and in doing so I ended up pulling a good bit of the render of the wall. I am thinking I will re-render so I a don't get any damp running through the blockwork. Would it be ok to render up the point of the vent and use that to 'hold' the vent in place?
I don’t see why that would not work 👍
@@ultimatehandyman thought so, should be fine tks
Rather than silicone to connect the pipe to the vent. Why not use uPVC cement? Permanent bond then which is 100% airtight.
Solvent weld will only weld solvent weld pipe to solvent weld fittings, it will not work on any UPVC (it has to be special UPVC).
Thanks for the comment 👍
Also if you extended the ladder to a safe height to work on would be a good tip for you and I hope you had someone footing it for you.
I always get someone to foot the ladder ;-)
Thanks for the comment 👍
We have a blocked up fireplace in an upstairs bedroom, with an airbrick about 2m up the wall.
Could we block the vent and create a new vent OUTSIDE? Either in the wall at the same height or even further up on the stack above the roof.
Not sure, might be best double checking with a builder.
As far as I am aware the vent inside is just to prevent stale air being trapped in the disused chimney, which can cause damp problems.
any recommendations for type of silicon? there's many to choose from
I normally just get a general purpose one, that is mould resistant 👍
Are both of these the same inch size? Just not quite sure how it will fit directly on if it’s the same size
The vent normally has a slightly smaller connector on it, so that it fits into the ducting 👍
good video chez....back to work next week ...looks like I will see you there then :)
Thanks Abid, yes I'm sure I'll see you at some point ;-)
If I replace the vent cover (face plate), does it need to be a sealed/tight fit with the tube that goes through the wall?. Or can I cut the old one off and screw a new one to the wall (it’s ground floor, no issues with height). ? Thanks
It's better if you can attach the pipe to the spigot, unless you can access it from inside, just because you don’t want the pipe falling off and venting to the inside of the property. It does not need to be an airtight fit though 👍
Hie can this be installed in a bedroom as I’m struggling with damp? Secondly my house has pebble dash is it possible for a while to be drilled through?
Yes, these can be installed in any room. I’d try and find out what is causing the damp in the first place. I know someone that lives in an apartment and she has vents like these installed in most rooms, the noise from road traffic is horrendous!
@@ultimatehandyman my house was built in 1979 and there is no insulation. It’s an end of terrace house but my exterior bedroom wall is the one that gets mould. The inner wall gets nothing so I understand it’s down to no insulation.
It's likely that your problem is not damp, but rather water vapour condensing on the cold wall, which is causing mould.
www.ultimatehandyman.co.uk/how-to/damp/condensation
You might be able to fix the issue, by cleaning off the mould using a dedicated mould removal product, then using a paint that contains a biocide, such as Zinsser Perma-white. You can even get paints now, which claim to insulate!
How does one remove such a silicone attached vent pipe/cover?
You can just use a sharp knife and cut between the vent and the wall, or perhaps spray some spray penetrant on the silicone and that will help to release it.
Thanks for the comment
Ultimate Handyman Thanks for the reply! :) What is a spray penetrant? Would a WD-40 work?
thanks for the upload. it's always appreciated. 👍
You are welcome.
Thanks for the comment
great video ,i have to fit an exterior wall vent in my lounge as i have an gas fire ,what height on the wall should it be fitted thanks
As long as it's not too close to the floor it should be fine at any height.
We had something similar and it was about 6 inches from the inside floor level.
Thanks for the comment 👍
@@ultimatehandyman thanks
Hello. Love your vids. Just moved into a new build and we have one of these external that leads to extractor in our kitchen. It’s letting a hefty draft of cold air IN from the outside though which makes that area of the kitchen cold. Can this be stopped? Thank you!
Thanks, yes you can get backdraft shutters, either ones that fit in the pipe, or a backdraft external shutter, you just need to get the correct size (I think kitchen extractors are normally 5 inch, but best to measure it) fave.co/2OLdQ76
Quick question, would you suggest/recommend running a bead of silicone around the edges for extra water ingress protection or will the silicone 'glue' be enough? Thanks.
You could do but in most cases the silicone used as the adhesive will suffice.
Thanks for the comment ;-)
Can you do some more videos on how to install CCTV cameras In different ways to what your home monitor cameras.
It's not something I intend doing, sorry.
I have looked at CCTV but to get a decent system with HD camera's it costs a couple of grand!
+Ultimate Handyman look at Swann CCTV systems
I did look at those a while back but someone told me they were not very good.
How do you clean wire mesh that inevitably clogs with fibers?
You can vacuum it out, or you can remove the mesh and clean it.
Thanks for the comment 👍
Thanks for the video. If going trough the bathroom roof would you recommend the extraction trough the soffit or roof tile? Soffit looks a lot quicker and simpler but I’ve found mixed reviews. Can find videos on this.
I have never done a roof tile vent, I always go through either the soffit or the wall (as long as there is an external wall in the loft).
Sometimes it's really difficult getting down to the soffit as there is not much room, the last time I did one I could easily reach out of the bathroom window and drilled the soffit from there, before making the connection in the loft.

that's great. thanks for the reply! Love your vids!!
I've just bought a house that has one in the bath in the ceiling, but vents into the attic not outside should it go attic or outside
Daft question I think how hard is it to vent outside ?
It should go outside, unless you have vents in the attic roof?
Venting a bathroom into an attic can cause the roof timbers to rot with the moisture!
We were getting condensation in our loft which was making everything damp, which is why I installed this vent. I cut the core out using a drill from the inside-
czcams.com/video/P0Pj9zzPN0s/video.html
Hello, thanks for the video, have you made a video on how to actually cut the huge out the wall for the vent pipe?
Hi, yes I have done that and linked to it in the description-
czcams.com/video/P0Pj9zzPN0s/video.html
Thanks for the comment
Do you mind if I ask how you would solve an issue of condensation running down the outside wall which we have coming from one of these? The vent is for a tumble dryer and the cold weather evidently causes the hot air to condense within the tube which then obviously turns to water leading to it dripping down the wall from the 3 vent flaps creating an unsightly water stain on our brickwork. Any help would be appreciated. Thanks
Is the pipe leading to the vent clear and unobstructed?
I assume it is a flexible type of vent pipe?
To be honest, I have never heard of this before, normally the warm air just exits the vent 🤔
Thanks for the comment 👍
@@ultimatehandyman Hi pal, no, no obstruction, I only installed it a few weeks back. I think it may have a natural condensing point and I’ve missed the damn thing. I have a 100mm flexi coming from the tumble dryer which is made of a firm but flexible plastic (standard hose that came with the dryer but had a defect). I have cut at the defect point and attached an aftermarket dryer kit. The original hose has a fantastic connection with a solid twist lock so the 500mm of this which I salvaged was priceless. This is connected to a 1m stainless flexi, also a 100mm in diameter that connects to a 350mm length of 100mm solid pipe that runs through both the inner block wall and exterior brick wall out to the vent. The wall vent sits flush to the wall and I have approximately a 5mm fall from the inner wall out to the outer brick which was recommended when purchasing the kit. The 10mm gap I had around the pipe (hole cut with a 110mm bit) has been filled with expanding foam and then exterior silicone at the outer wall vent.... but.. I think the hot air is being condensed naturally in the solid pipe between the wall cavity, it’s an older house with very little in the way of insulation between walls.
The vent is approximately 400mm off the ground and roughly 300mm from the mains water inlet.
The wall shows staining below the vent especially on cold days and most nights to the point that I’ve since treated that area with Ronseals wall waterproofing .. I don’t want it affecting the red brick over time and with a 7month old baby I’m sure you can imagine, the washing machine and dryer are in constant use. I’ve also wedged all 3 flaps of the vent open very slightly to allow more free flowing hot air to escape.
I was thinking of drilling a few internal holes to the cavity (10mm) and trying to inject the area with expanding foam to see if that helps but I’m at a loss, it’s either that or trying to install a motorised vent which I dread having to rip everything out again. Sorry for the long winded reply but any help, tips or advice would be appreciated. Thank you.
@@ipod1978 I can't understand why it is condensing in the pipe, I have never heard of that happening before!
The only thing I can find about it is this-
www.doityourself.com/stry/how-to-prevent-dryer-vent-condensation
@@ultimatehandyman Gentleman as always and thank you for taking the time to reply. That article was an interesting read and I’ve since bookmarked the site so again thank you.
The Ronseal has helped a little and I’ve since recoated the area again but one option that was presented was to remove the exterior vent from the wall and fit an aftermarket plate and extension that would push the vent 20mm -50mm off the wall entirely. Not ideal but I guess a solution if the problem worsens. A little unsightly and not the desired flush and clean look I was expecting but I’ll see how things develop. Roll on the spring when we can use the washing line again lol.
Thanks again for your opinion and help pal. Looking forward to more videos this year.
Very informative good video.
Thanks for the comment ;-)
enjoy the video.
Thanks for the comment ;-)
Could you not mark holes and drill for wall plugs first?
It's best not to drill a wall at height, unless you have scaffolding erected.
Lots of people die each year from ladder falls.
Thanks for the comment 👍
@@ultimatehandyman sorry saw your vid and indeed at that height I can understand. Not worth risk
Like the video, but would have like to see how you drilled/cut the hole out.
Thanks, I put the link to that video in the description and also added a card to the video, but here it is-

As I know I'm not allowed to touch bathroom or kitchen electric but I want to install an over the shower in-line extractor fan to a spur socket I had put in the loft and have the on-off switch run down into the airing cupboard, would this be ok.
The rules have been relaxed somewhat since PartP was first introduced. I recently contacted my local building control about replacing a bathroom extractor and they said it was not notifiable. I'm afraid I do not know the answer (as the council probably don't either) but it's best to check with them before doing any such work ;-)
Thanks again for your advice, I'll have a look at the councils web site.
You are welcome ;-)
2 questions. 1. what if the house is stone built will the grab ahesive still work against such an uneven surface and 2. How did you get that perfect hole in the wall?
It can be difficult on random stone. Sometimes you can use this method by using a good non slumping grab adhesive, then take the vent cover off before installing it so that you get it as neat as possible before refitting the cover.
This is how I made the hole from the inside- czcams.com/video/P0Pj9zzPN0s/video.html
Thanks m8
You are welcome.
So how does one go about replacing the vent part?
You can just use a knife to cut the silicone, then remove it.
Thanks for the comment
@@ultimatehandyman Is it separated from the pipe that enters the house? If so, I'm screwed.
Can an extractor be vented into a nearby soil stack ?
No, that is not a good idea!
Thanks for the comment 👍
@@ultimatehandyman Damn!
Only if you want sewage odour on your cooking
How much should I expect to pay someone to do this for me please? There’s no way I could get up a ladder to do it myself.
Not sure, sorry.
I'm afraid I do not do work for other people, so I have no idea.
Thanks for the comment 👍
you can tell it's an older video you looked slightly younger then lol
LOL ;-)
It's very dangerous to drill on a ladder 😂😂😂😂😂😂
I know a guy that fell from a ladder when drilling, he ended up in a wheelchair for a few months before he died!
