What I like most about these videos, is that they are professional but not staged. Its rarely helpful watching DIY videos in a mocked up room where everything is just perfect.
Bob Villa who? You are the man..Love all your videos. As a Diy'er I can't thank you enough for your insightful and educational videos. May God bless you and your family.
I just installed a new bathroom fan in my basement bathroom with the help of your video, thanks! Also, thanks for the recommendation for bathroom fan. We decided to go with the NuTone fan with the built in light to give a little more light. Thanks for the video
Got this unit recently, loved the video. Thanks.
This is one of my most favorite videos by you great work you do & thank you for all the knowledge you teach an show you've been one of my favorite roll models to follow thank you good sir, remember even the greats needed breaks lol :)
Great video as usual, keep the content rolling!!!
I’m a “fan” 😆 Subscribed!
As a sheet metal journeyman I would recommend taping not screwing an extension piece of pipe that would be long enough to go through the hole you cut, and putting it on from the outside. then banding on the flex. You could also insulate this pipe by pulling just the insulation and outer sleeve through the hole all the way to the outer floor joist. Work smarter not harder
Enjoyed your tutorial and learned much.
i love to watch and learn from ,you done good job .
Awesome video great production!!!!!
Thanks 🙏
At 9:18, you mention adding drywall up to the fan shroud. However, it wasn't made clear whether sheet rock sits above or below the lip of the fan shroud. Please advise. Thanks!
Great video!!! Very informative and concise!!
Thanks, I appreciate it!
You know everything about home renovation.
You are the best man. I always watch your videos.
Thanks , Cheers!
You're awesome man!
I like a noisy bathroom fan, helps with "privacy" lol
btw Loving the videos, best diy instruction on youtube that i've found.
I have found a great solution for creating a sound proof room. Great for master bedroom and bathrooms and theater rooms. will be sharing ther vid this summer.
@@HomeRenoVisionDIY do you have a link to this?
I thought there was a fly in my house at 10:38 🤣🤣🤣
I always enjoy your videos, straight to the point! 👍🏽
Cheers!
Very instructive video. Thx man
Cheers!
Just subscribed thank u for your expertise! 🙌
Thanks for video i looked this up before I do mine in a bit
Best of luck with the project. Cheers!
Your my go to guy, if I need to learn anything.👍👍 Thanks Man. I appreciate all the info.
Awesome, thanks man. Cheers!
Any videos on what type of vent terminal you use on the outside? Easier or preferred to go outside though the side vs the roof?
The video mentions builder made a 4" exhaust drill hole. The flex pipe dia is 4" too? Ontario Building Code (OBC) Table 9.32.3.5 states a 5-6 inches bathroom exhaust duct diameter.
Do I need to add leave 5/8 inch between the fan flange and the joist for the Sheetrock or do I need to sandwich the flange between the joist and the Sheetrock?
I've been looking everywhere for an ADCFM fan.
Very nice！
Thanks Charlie, !
Hey.. Love your videos... Do you happen to have any videos on Make up Air dampers and how to install them for hoods that provide more than 400cfms?
Hello Jeff , like renovations videos. My question is have you work on moiblehome renovations repair. Examples under moiblehome heat vent?
Love watching your videos! You are truly gifted with teaching and Reno skills! I have one question for now. Is it ok to install exhaust fan vertically? Like on the top of wall instead on the ceiling. I'm looking forward to your wise advise. Thank you!
Sure but make sure the fan says for vertical installation. not very common but if you go to an electrical supply store they should have access to one or 2 models for you. If you cheat you will find it gets noisy quick and burns the motor. Good luck. Cheers.
Home RenoVision DIY that's what I'm thinking. If the rotor bearing is not for vertical load then it won't last. Thank you very much!
You work always neat. Very informative video. Keep up the good work. Thank you.
Thanks A G . I try to work as clean as I can. I find myself frustrated when the site gets messy. So much easier to work in a clean organized environment. Faster too! especially when you are always looking for your tools.LOL
hi Jeff , I just would like if possible I can connect my bathroom exhaust fan to my laundry exhaust fan ... they both located in same room .. thanks
Your awesome
Cheers!
What kind of utility knife do you use.
Sorry if you answered this in the video, but I was wondering how crucial placement of the fan is... can I mount one over the shower? or does it have to be over the toilet ideally... Thanks!
The housing needs to be secured on only one side with the ceiling stud?
Can you connect more then one fan duct together and have only one pipe going to the roof?
Is it necessary to run duct work on a half bath? Only toilet and sink. Thanks
Is it recommended to use the insulated duct even when you're inside a heated space? Or could you use solid uninsulated ducting until you get into unheated space?
Hi Ken, Yes for sure. since the exhaust does not stop the cold air from entering the ducting there will be a few feet until the cold turns to warm and that is where the condensation happens. If you don't use the insulated pipe you will increase the condensation factor by at least 20 times more and then you are into a water problem since it happens on the exterior of the duct. If your duct is insulated thern the small amount of condensation happens on the interior and it can be dried out while the fan is in use. Cheers!
@@HomeRenoVisionDIY should we use duct as short as possible to avoid condensation? My contractor just installed my fan with an insulated duct in a ">" shape, and I think the duct is now at least 6-8 feet long while the actual shortest distance from roof to bath fan is only less than 3 feet. And during recent cooling weather, I can hear water dripping but when I check the fan itself it's all dry, I guess the water dripped in ">" shape duct and collected somewhere. So should I just take out the fan and shorten the duct and reinstall it straight up to the roof?
Great video with simple, easy to understand straightforward explanations.
Is that ok that the placement of the duct's end in the outside wall is higher than the fan itself? Will not the condensed water stay in the duct that way? I already have a 4” duct connected to the kitchen fan and it is running about 10” above the place where I’m planning to install the bathroom fan. Can I connect bathroom fan to that duct? Thank you.
don't add ducts to an existing system and yes a little condensation will dry out every time you turn on the fan. simply include a low spot so the water does not run back into the room. Cheers!
new fan video coming out tomorrow. you should check it out. Cheers!
Do they all require a dedicated circuit?
I took an old one out that measured 8*15 but when shopping for a new one I am seeing *require dedicated circuit*. I am not sure if this was the case as I just purchased the house. How can I verify this?
On a townhome, where is the best place to install a vent pipe to pull toxic secondhand smoke from in between the wall and vent it in the attic?
I installed a new old stock Leigh chrome exhaust fan in my kitchen ceiling. It is ready to be vented. The plan is to run it our the side wall and the fan is the 10 inch model. I could run 10 inch round or reduce it to 8 or 6. The benefit of reducing is a smaller wall cap. What would you do? This is a little 8 x 9 kitchen in a 100 year old house and I don't need massive ventilation, but it is a 10, and my inclination is just to run all 10. That big cap could look ridiculous. Thank you.
Do I need to drop the fan rim 5/8 for the Sheetrock or sandwich the flange in-between the Sheetrock and joist?
drop it for the finished ceiling is easiest for installing the finish grate.
I am adding a new washroom on my upper floor.How do I coonect exhaust fan vent in the attic ? Above the ceiling my attaic is first inuslated and underneath the insulation there is a thick plastic sheet as a vapour barrier. Do I have to cover the exaust fan in the plastic sheet to install or just install it in the ceiling without the plastic sheet ? Because as soon I remove the platctic sheet above the celing from drywall than attic insulation starts to fall down in the wash room. Please advise do I have to rap the exaust fan housing in the plastic sheet to prevent insulation chunks going in to the fan, s motor and keep it safe from moisture or just install the fan with out plastic sheet ?
If only doing this was as relaxing as the music
Great job on the videos. I'm also in Ottawa so it's fun to see DIY videos that use parts and materials that I can find in Canada. I'm placing a fan like this one in my upstairs bathroom and I want to vent through the roof. What type of cap do you recommend for our weather? Plastic? Metal?
Not going through the roof. I recommend going to the gable side of the house or soffit before the roof. Cheers!
@@HomeRenoVisionDIY Sounds good. Thanks for the quick reply!
I am a maintenance technician in with a lot of things that you do reminds me of me but the difference is I'm only 27 and you look like you're 40 something maybe you know going in your early 50s I love watching your videos for the most part, they are very educational I had my own business going but I just couldn't keep up with it maybe I might start it back up when I get a little older and wiser !!
When did you start your own business
28 years ago
I would have thought you would frame it with two by fours. And drop it 1/2 inch for drywall
That's exactly what I was thinking
Hi Jeff, Home RenoVision DIY,
I have a question on the Kitchen exhaust duck size and pipe.
Is the code requires 6" duck or 4" pipe is ok?
I am trying to add a range hood exhaust fan in a old kitchen that had no external vent.
I have the ceiling open and 4" seems do able, but passing 6" duck pipe will be difficult.
May be you can do a video on Kitchen exhaust fan installation and duck setup.
Thanks in advance.
I have a bit of a problem I have a bath with 12 ceilings and I like to put in an exhaust fan I was thinking on the wall instead of the ceiling to bring it closer to the action. The wall I was thinking is an exterior wall so I thought would be easier?
Do you have a video to install the exhaust fan for the kitchen or fix drill holes in a popcorn ceiling and repair? Those are the two home projects I need help with. Example, I need to drill the holes through the ceiling, out the roof, etc. I’ve seen your video for how to install the vent hood but I don’t have the hole vented outside.
holes in popcorn just use latex caulking and you are good. The kitchen venting we will cover this spring. Cheers!
Home RenoVision DIY Cheers 🍻 and merry Christmas.
Can two exhaust fans be connected to the same line. For example if we would like to install a bachelor style kitchen on the same wall within 8 feet of the bathroom.
sorry you can't connect the kitchen with a bathroom.
How can I install an exhaust fan in a bathroom in a condo that does not have a window. I have one of those old fans that just circulates air in the room. Can a channel be connected to the AC duct?
Holy cow, I’ve just realized that I’ve been watching your videos for a couple years now but I’ve never subscribed.
It’s s done now.
Shouldn’t dryer vent piping be solid pipe?
Hey Jeff - I just found you on CZcams and like watching your videos. I have a question. My bathroom has an exhaust fan in the ceiling. I feel the cold air blowing through the fan, making the bathroom cold in the winter and hot in the summer. The wind can e a strong that it turns the motor. Any idea what could be the problem where air blows into and through the fan?
Is it vented into a soffit or through vent out of the side?
Spray foam insulation... Is it safe???
Question: Is it ok to cut a 6" hole for a kitchen exhaust through a 2x8 rim joist?
If it is truly a rim then you will be fine.
Great video, love the content! However, I would be more cautious when pulling the duct throught the metal box because it could have cut the duct resulting in mold in the ceiling.
It's not that delicate. No worries!
I have a Karsten K 20 modular double wide and the two vents in the master bath allow cold air to the toilet room and shower area.
I’ve had a new shingle 12 pitch roof installed and the toilet room has a skylight with vent. That stays warm now. The master bath/shower area is still cold. Both vents escape through one roof vent.
What do you recommend? I cannot reach both vents through the small opening at the roof top section.
put in floor heating in the shower area. Cheers!
Why if your bathrooms ceiling joist runs parallel to the bathroom window and not perpendicular. How you duct the air outside without cutting holes in the joist?
Is a Damper not needed?
Wish the builder never cut the hole. So much easier to cut between the joists and have a straight duct line.
I had done mine before watching this video, but I still watched because you are such a great educator and I enjoy your videos very much.
I wish they hadn't placed a joist so close to where they knew a duct line was going. Thanks for the kind words.
Awesome video! I'm about to do this project myself next weekend. Quick question for you, my rim joist is currently used for my rear deck as well. Can i simply drill through just as i would if there was nothing attached to the rim joist (and therefore going through the rim joist and through the frame of the deck)? Thank you for making these videos, incredibly useful!
Sure thing Maximus. Just remember the rim joist is like 1 huge point load to the foundation so any hole is acceptable. Secondly the ledger board for the deck needs to be attached on the interior of the joist closest to the hole on both sides with a lag bolt to maintain structural integrity. Good luck. and if you are going through that much wood I would suggest using a good spade bit or auger bit to drill the 4 corners of the hole before using the sawzall to open it completely if you don't have a great drill and hole saw kit.
Awesome, Thank you for your quick and very informative reply! :) Keep the videos coming!
Will do Maximus. Thanks for the comments.
HI again Jeff! Always enjoy your videos. I am interested in seeing what you need to do to install a range hood exhaust when there was no previous hole. A hole in the roof would not be likely because there is another floor above. The outside wall is wood and probably lathe and plaster - no brick or cinder block!
@@HomeRenoVisionDIY I prefer yanking my wrist with a hole saw when it's an inch through ;)
What kind of drill bit is that? (Has a good length to it)
I like em long to make up for my shortness. Cheers!
I literally just did this. Hahaha
Hey Willie, did you use the same fan?
Home Reno Vision DIY No I put in a Broan AER80C. It's also 80 CFM and it's 0.8 Sone.
If you have a 4" exhaust you will be fine.
If not you will probably have a 1.8 sonne
This is a level 9/10 difficulty job
Do you have a video where you're making a NEW hole in the foundation wall?
Not Yet!
Easy peasy, diamond core drill rental and a measuring tape
Depending on what joist manufacture you are using I know you are not allowed to cut within 12” of a bearing point..... including the ends. Look at the free truss joist hole cutting diagram. Free on google
the Joist is not a load bearing one. It is an extra one inside a 20" space.
Installed a similar 80 CFM fan by Broan. Seems like a popular model, nothing special, but has an issue. When you first turn the fan on it's whisper quiet. The moment you attach the duct (granted it's a 3" duct with a reducer) it gets extremely noisy. As loud as the rusty Broan from the 80's I was replacing! Any ideas on reducing noise/ fan chatter? Under-volt it? Others have similar issues.
You have resistance. You need to replace the 3 inch line. Also make sure the run is as straight as possible.
Thanks! The 3 inch line goes through a multi level condo, probably 25 feet away with lots of bends. I might be "hosed" har har.
Sorry to hear that. That is a poor design you might be stuck with. I would contact panasonic to see if they have a fan for just that situation. They seem to be the leaders in quiet technology.
Yes, straightening out your line will help greatly, Broan has as good or better (quieter) than Panasonic (less$$ too, check out the RB80) but even buying the most expensive quietest bath fan, if your unable to redo your ducting and increase it's diameter you will have to do with a noisy fan.
Are there any considerations to be made for installing a fan over a shower?
only aesthetics!
Yes, the electrical circuit has to be GFCI ‘ed to be code if the fan or light fixture is in a shower.
How to up dry wall
We have videos for installing drywall on ceilings.
Can you wire the fan to the light switch or does it need it's own switch?
Yes you could run a wire from the light to the fan, or run a wire from the switch to the fan and splice it to the witch lag.
the answer is yes
I am thinking you should put New rafter in between the old couple to distribute the load of the hole in rafter
There are already 3 in the 24" space. that is more than enough.
Agree. Engineers designed this beam and he cut a hole in it.
Get a loud fan.... you dont want to be hearing anyone dropping a deuce... ;)
lol
Mine has a bluetooth speaker in it.. great for pooping or even showers =D
@@chokumYnai I was thinking the same thing, lol! That fan serves more than one purpose, and the noisier one is cheaper! Lol!
I was with you until you decided not to support the other side of the fan with some 2x3's. Other than that, nice !!!
In this installation I am installing the fan flush with the framing. After the drywall goes on I rotozip the hole leaving the fan flange resting on the drywall. Tons of support. No different than a replacement fan resting entirely on the drywall.
Plus he did add another 2x4 for extra support, perpendicular to the beam.
So it's not necesary to run exhaust to the roof, right?
right, you can go out the gable end which I prefer or the soffit. Cheers!
Can you just have the ducting air into the attic?
I was told thats ok
Or is it bad?
Air must exit attic through duct. Prolonged exposure to moisture can start wood rot in the attic and lead to metal rusting problems.
CAn this exhaust just go to the attic? does it have to have duck to escape outside?
no it needs to find an exhaust from the structure or you risk mold problems. Cheers!
Pump warm air into a cold attic or cold air into a warm attic and you have moisture. Then you have mold. Then you have a headache. Being a pharmacologist, my solution might be a little different to remove the mold, but fortunately I haven't had to do that yet.
I'm thinking of installing a bathroom fan in my first floor bathroom. I own a 50's semi-detached 2 storey duplex with brick all around. Currently bathroom has no fan, and the steam is a big issue. Joists(2x8's) run parallel to exterior wall, so I'd have to drill 3" holes through at least 2 floor joists, the rim joist and brick. My concern is the safety/legality of it. Is this a DIY or should i get a contractor?
I would suggest a small bulkhead in order to run the fan line below the joists. Cheers!
toss in a couple pot light and make it intentional and part of the design.
I think u should try Indian company 😉 easy to install .
Make sure that there is an 1\2 inch air gap at the bottom of the bathroom door so the vent fan will last.
Very good practice. Thanks Roy
Roy 8
Was wondering about the immediate bend. Most fans specially broan and panasonic ask for 2 to 3 feet of straight run. I know it is not possible in all cases like yours. Do you see an issue? I have an inaccessible attic and the joists run parallel to the gabble wall and need to do this as well. We also have very harsh winters and the R8 insulation is not enough. My only thing is that the duct will be 5 ft long at most. With the flex i can have slight curves vs the rigid which is sharp turns. But i like the easier cleaning of rigid
You gonna wait the electrician to connect 3 wires ?
why you used a flexible duct with insulation instead of Bare Flexible duct ?
In the winter here it is so cold that we need to have the first 3 ft insulated. The rest is for convenience.
Home RenoVision DIY is that code to have it insulated near the outside? I’m in SW Ontario and will be installing one soon in basement bathroom.
@@hawkcrave hey Craig most likely you're going to shove roxul in the ceiling after anyways so I don't really see the point.
Where’s the wiring up of it
I hate those flexible duct lines. Solid is way better, but in your situation, you didn't have much of an option...
Good tutorial....
I agree they cause a little bit of turbulence but sometimes it is the only option. For a quieter ride just use solid pipe and slip the insulation cover over it as you go.
I don't understand why bathroom fans advertise 80 cfm when there is no way a 4" flex duct can move air through it at that rate. A duct that size can handle maybe 40-50 cfm (using average values in ductulator calculations). To get 100 cfm, you get a 6" round duct, which you never see in bathroom fans. Makes no sense! This is even worse when the duct is squished into an oval!
BTW, great video!!
I am not too sure on the science either. but since the fans come with a 4" exhaust going to a larger exhaust pipe is kind of redundant.
@@HomeRenoVisionDIY The video mentions builder made a 4" exhaust drill hole. The flex pipe dia is 4" too? Ontario Building Code (OBC) Table 9.32.3.5 states a 5-6 inches bathroom exhaust duct diameter.
That is lot of work even to replace one
yes but it is vital to protecting the space from moisture damage and mold growth. Cheers!
Why did not you just use a regular duct line instead of insulated duck. Just wondering
It helps to reduce the condensation that would occur.
Thanks for watching.
if it's only a exhaust we use bare flexible duct not the insulation , because there is no way to prevent the moist.. its only for the exhaust not air cooled.
Hello Jeff, We had our basement completely finished by a local contractor. Before our basement was finished we took a lot of pictures of before during and after. We would like to ask you a few questions about the bath fan venting and duct work process. Our contractor ran the bath fan duct work to an existing vent that was already installed by the builder when I bought the home brand new in 2005. When I am in the basement standing in our furnace room I feel the cold air coming in through the floor joist which is the same run that was used for the bathroom exhaust duct work. We are concerned why we are feeling cold air Is this normal? We live just outside of Cincinnati Ohio in the suburbs. I would really appreciate your help and input. I have pictures I can send to you if that would help. Thank you very much.
Hi Mark, my guess is someone moved the insulation from around the exhaust pipe in order to attach the new exhaust line. And then forgot to put it back properly or at all. The other possibility is that the exhaust cap the builder installed has been removed and then they forgot to install the ducting from the fan to the exhaust. This can be checked visually from the outside. Either way it looks like you will be opening the ceiling to repair, or you risk condensation and mold developing over time. Cheers
Thank you very much for that info Jeff. I was able to check and confirm that the duct is properly connected to the vent cap that is vented to the outside. I checked it from our unfinished furnace room with a ladder to look up into the floor joist where the exhaust duct was ran in between the joist to the outside. The contractor who finished our basement did put the original builder installed yellow insulation back around the connection where the exhaust duct connected to the outside vent cap. Is it ok to add more insulation in the floor joist above the opening in the furnace room? For some reason we can still feel the cold air coming in just in that open area of floor joist where that exhaust duct is ran. Is that cold air coming in need to be like that for venting purposes? Thanks again for your time and help. Mark
dang..wish you had had to drill the exhaust hole...still great video...
2 ways, 1 with a 4 and a half inch hole saw. second cut out a square that will be covered by the dimension of the flange on the exhaust . Use a spad bit to drill out the 4 corners and then connect the dots with a sawzall once you have cut any vinyl siding away first.
greatly appreciate your response...seriously..never thought i would hear back... and i was ready to cut 6"....lol
I can't really see what the crimping tool looks like. My husband is having a terrible time installing the flex duct work on the stationary sleeve. There is some very colorful language coming from the basement. HELP!
Hi Angie check out my Amazon link and type 5 blade duct crimper tool. Cheers!
Love your shows but I'm confuse with why you never seem to wear safety glasses for your own protection
I do when I am doing something dangerous. Constantly wearing glasses reduces my field of vision and increases my chance of accidents.
@@HomeRenoVisionDIY I love the honesty. My glasses fog up pretty quickly when I work hard, and just a few scratches make visibility less than acceptable for me. Was that cellulose insulation?
You had to call an electrician to splice and hot and neutral?
Maybe he just needs to say that . He might not be a certified electrician saying he's doing electrical work publicly with no license could get him in trouble
Silvano Rasta: He replied to another person with the same question, and for new construction in his area, the electrician needs to do it. That infers that if you are replacing an existing fan, that this is not required.
Air supply is too close to exhaust .
that was set up by the builder and passed inspection so I guess things are different here. cheers!
Who else thought he had hella stash of weed @ 00:56
Guilty...
Well if you had any sense you would know that it's mineral wool and stash of weed would never have crossed your mind
When we built our house the engineer made our builder add another joist when it cut a whole that size. It matters. Your house is thousands of pounds. His example is wrong.
You called an electrician to wire an exhaust fan???
new construction on a clients house. only a licensed electrician can wire a fan!
