Repairing Ductwork - How to Repair Large Holes in Ductwork
Now as you're going around inspecting your ductwork and cleaning it up and getting it ready to put mastic or seal it up in any way…You may find some surprises and I'm going to show you what I mean.
I found some huge holes, and when I mean holes,I mean holes…holes like this. The size of my hand, I can stick my hand in the ductwork.
So obviously we can't leave it like that. So I'll see if I can get the video camera up there and show you how I fix it. But uh, basically I'll take you over to the work table and I'll show you what I'm going to do.
So the hole I found up in the ductwork is about 5 1/2 inches in diameter. And what they did was put duct tape over top of it and of course…duct tape, I don't know over time it breaks down it's not made for actually working on ducts for some strange reason. But um, anyway…
So what we're going to do is we're going to take a piece of scrap sheet metal. Now this is just a piece of a duct that I just bent and it's the same material that the ductwork is made out of. What we're going to do is cut this close to the right length and we're going to seal it up with some mastic and screw it down with these self tapping screws.
So with the sealant underneath the hole and when we screw the metal down it should give us a nice strong bond. And keep everything, all the air that we are paying for to stay or go upstairs instead of staying downstairs here in the basement where we don't want it.
I wondered why my basement was the warmest room in the house…and now I know why.
