Sealing gaps in duct work letting out air
(sh.itjust.works)
I'm seeing a crack in the corner of the ducts. Can I just tape it shut with boxing tape or is there a better way to do it?
Also, one register in an unfinished area is turned off but I can feel it leaking air. I looked inside and there's clearly a gap letting air past too. Can I also just cover the register in reflectix and tape that shut too or is there a better option? Thank you :)
Thank you everyone. I'll wipe the area first, then give foil tape a try. I might use mastic for a better seal if it doesn't cost much more.
