One of the few people that actually mentioned to clean the ductwork before you apply the tape. It may be fine on new construction just to slap some tape on, but there is so much dust and crud on my 30 year old duct work that there's no way anything would stick to them without getting the layers of dust off first. Good video
Caulking? Never heard that one. Mastic maybe, foil tape yes. You hardly see people rub the tape after. Take that 2 seconds more. You can actually flatten to a clean look. I thought you were gonna insulate the ducts. You just taped them. If you have open ducts in an unfinished basement. You should look into using a wrap insulation around the ducts. Thermal loss occurs from constantly heating cold vents. If you add a thermal breaker wrap it will help. It's like going outside in the winter with a sweater on. It helps. I'm trying this thing called reflectix duct wrap. It's like $30-40. It's like bubble wrap with foil on both sides. Can also be used to wrap water lines. I know this vids old. But people are doing crazy renos this year.
I've used the aluminum tape but putting silicone over the seam first?! At a duct joint there is a metal "joiner" part that holds the two duct pieces together. Do you caulk on both sides of this metal strip? I wish you'd shown a little bit more where *exactly* the caulk goes. And is it just plain silicone caulk or there is something more specific for this kind of a job. Thanks!
Another great video! I'm trying to find a solution that's cheap and leak free for my square ventilation duct. Kind of like a self seal connector? Can you or anyone else help?
You don't need to seal small leaks in return ducts at all, if your furnace is in a heated space, like a normal basement, even if it's an unfinished basement.
I beleive I have major leakage in my unexposed ducts. I have 10 registers. Only two have good a/C or heat. They are in the master bedroom and bath on the third floor of a townhouse. The force if the air feels like 20mph. All other registers output air that is very weak in speed as well as desired temp. Be it for a/c or heat. There are two bedrooms and a bath on the second floor. The first floor is all the other registers. I'm renting and I know the owner isn't going to rip out the drywall throughiut to seal duct joints. Is there a magic sealant that can be blasted through all the duct work that will seal any leaks?
great vids, question what do you recommend for return ducts that come into the attic? obviously seal it up as good as possible, but do you typically build some sort of box for it from foam to get the rvalue up simulate an internal duct environment?
An inside corner like where he used calking is really hard to tape with foil tape. Just try it and you'll understand in a minute why. Unless you use something like 10 small pieces of tape.
i have flex ducts that are partially squished into the ceiling joists, so that batt insulation can fit under them. they protrude down from the joist some, obviously. maybe they thought sticking drywall on the ceiling would be possible, than. is there a proper way to fit the duct while insulating the duct and ceiling, so that no cumbersome bulkhead would be necessary?
The air return system wasn't designed to have an input there... that means that the inputs that were designed for the system are not being used efficiently. Ultimately this will result in uneven temperatures throughout the house.
hi. You may not realize it, but you are staring at my ducts.... seriously, who tf doesnt know what an air duct is, and if they dont, they have no business being up in an attic or hvac closet after watching a cheezy, over simplified youtube video.... and fiber reinforced mastic paste is far superior to tape and caulk.

Easy! Good stuff. Just what I needed
You're amazing Corey...great job!
Another good video, keep them coming.
Great info! Subscribed! "One side sucks and the other side blows" killer dude! lol!!

trying to fix my furnace and think you are funny (my fav kind of guy)
i like the portion after two minutes in the video.
Your adorable! Thanks for the info. Super helpful!
you're
Corey has his Ducts in a row.

Looks like you used high heat furnace cement (mastic) on your supply/return duct seams as well. I paste and foil tape all my joints.
good lil' video there
How do you insulate the cold air duct (vey cold when it’s -40 outside) it’s exposed in the unfinished basement. (Making the basement cold 🥶)
Why didn't you use the same tape for the blowing section instead of silicone?

great video thank you man
"Don't use duct tape on ducts." What a crazy world we live in.
Just wondering how did you decide to use the tape in one spot and caulking on another? Is it based on which direction the air is blowing?

Why would you use caulk instead of mastic? Couldn't you use mastic and then tape over? Or tape and then mastic over?
What about duct sealer like Duradyne sealant.
Why use chalk but not mastic?
@CatherinePoloynis Thanks for watching Catherine!
specifically the old solid metal duct (early 70's era) not the new flexible stuff.
Sealing air return in a heated space? I don't get how that saves energy

My supply sucks and the return blows
I have a bro-crush on this dude.
Ohhhhhh. Your ductttts. I get it
Please don't use foil tape to seal air leaks. Use mastic tape instead.
