transite flue pipe

[mdhills]

If you have the wall open, would you remove old, transite vent pipes, or leave them in place?

Our 1950's house has two transite flue pipes in the walls -- one is the vent from our hot water tank, the other was a vent for the oven.  Transite is an asbestos-containing cement compound.  My understanding is that it should be stable if left, unused, in the wall (presumably leaving the roof vents in-place, as well).  We do have the walls open now, so this would be a reasonable time to remove the material as well.  Does anyone see downsides to that approach?

thanks,
Matt

I would likely make it gone so it doesn’t come into play for a future sale.

Do it correctly, safely, etc. Have the proper abatement people remove it. If you found some you may have more.

As Blackhat said, you do not want it to become an issue down the road. You now know about it, so....
