Best way to seal off retired heat register

joe71March 29, 2011

We are doing a kitchen remodel, and the new configuration will have a cabinet in front of our heat register. So, our installer made a new floor register for us using some flex duct. The original register needs to be sealed off, so the installer put a piece of drywall over the opening. However it seems to be leaking a bit (into the wall and basement)and I am wondering if there is a better way to seal off this duct opening (the duct opening is in the wall, at the base of the wall). Any ideas?

Thanks in advance.

Do you have access from below?

Find the line feeding the old duct and remove it, then close off the hole left in the remaining duct.

Echo what was said above. Otherwise it sounds like the duct leading to the old register is still trying to deliver air?

Thanks brickeyee. That makes sense.
Another question: What is the best way to seal off the hole in the duct, once I remove the feeder? Should I just tape a piece of sheetmetal over the hole?
