Duct Work in Basement leaks & noisy

[Bill P]

I have a few questions regarding duct work in a walkout basement that I want to finish by boxing in the duct work with drywall. We have both a furnace and air-conditioning that use the duct work.

What is the best, long-lasting method for sealing holes / leaks in the duct work?

There seems to be a lot of noise that travels between the first floor and the basement via the vents in the floor on the first floor. Is there any way to sound proof this?

What is the best way to get rid of the noise made by the duct work that can be heard in the basement when someone is walking on the first floor (sometimes a popping noise and other times just squeaking from the ducts)?

Thanks

Do you mean that they are on the same pipe run for up and down???

any loss in the basement will still be in the home so Id say let it alone if its not to bad . There is a mastic for duct sealant you can buy

Have some one walk on the floor and find it. Can be a joist and you can put blocking in them. a wood shim on the duct where it hits the joist. This you have to just play with
