Asbestos-wrapped Ducts - Remove, Or Not?
Gentlemen,
Ancient house, old hvac system, noticed some white papery-stuff wrapped around a couple of supply ducts - just an inch of it sticking out the (unfinished) basement ceiling, but clearly it's wrapped around the ducyt all the way up inside the wall to the second floor where it terminates at a register. Had a small piece of it tested, ya, it contains asbestos. So I'm having anything exposed removed by pros and the duct passages in the basement ceiling sealed, no problem. But what about the stuf in the wall? I've come across two schools of thought: 1) It's sealed inside the wall and it's on the outside of the ducts, so no way can this be an issue for occupants. Seal the basement ceiling passages and forget about it, there's no problem. 2) If it's in there, it's a problem waiting to happen, get it outta there. Have the remediation pros rip it out and re-drywall. It'll cost, but you'll sleep better. What do other renovators or remediation folk think? Thanks. |

Re: Asbestos-wrapped Ducts - Remove, Or Not?
This is very common in many homes here in Vancouver. We run into this all the time. The problem is that every seam on your duct lines will have it. The runs up the walls will have even more.
With the Asbestos's age the tape is brittle and fibers on the edges are very loose. Cleaning your duct lines will disturb these tape seams and let small fibers go air born. You should remove it all from your home and hire a pro to do this. If you want a short term solution paint the seams with Zissner Shellac based Primer. This stuff stinks to high heaven but will help keep the loose fibers in place. Some spray foam around the edges where the duct enters the stud walls will help stop air movement inside these areas. Wear a mask and take care not to loosen the fibers on the tape. Once you breath them in they are with you for life. Good Luck. Work Safe.

Re: Asbestos-wrapped Ducts - Remove, Or Not?
I believe if meomry serves OSHA requires you to stop work immediately once you find some asbestos and have it all abated. I worked in a building for three years that had asbestos through out the entire building including the ceiling. Also the house on base that we lived in for about 6 months had it. I would have perfered if they had abated all of it but you know the government. So my wife and i will probobly have some problums down the road.

It's not an issue, untill you disturb it.

bob cntrctr - your post does not state whether you need to disturb it! If you don't disturb it press on. If you need to disturb it, have it done by the guys in the hasmat suits.
