I will be working with a friend to install new (much larger/longer)
windows in a house with Asbestos siding. Significant pieces of the
siding will need to be cut into and ripped out to make room for the
new window frame, etc.
1. Is this dangerous? Ie. does Asbestos-cement siding present a
similar health risk as free-form asbestos insulation?
2. If so, what precautions can be taken to insure safe cutting or
removal? I'm concerned this stuff might get airborn if we simply cut
3. How can this material be properly disposed?
Not nearly as much. It is only the airborne dust that is a problem and you
will not have all that much of it in the whole scheme of things.
It can be landfilled.
If you want to do it properly, do a web search for asbestos on government
sites. There is one I saw noted on this newsgroup that had a lot of good
information and it simplified the job. Most important, it told you the right
way so as to avoid legal problems from a cranky neighbor. It is really not
a big deal to remove the shingles, but better to know what is involved.
Well... the legal way to do it involves tenting the area in question,
misting under the tent, pumping air out through a giant HEPA filter,
and wearing respirators, but that's a bit excessive if you're not
making a living at it.
Personally, I'd wrap it in plastic, tape in in a box, and
hide it in the attic, this being marginally preferable to
burying it in a cement slab that someone might drill
Find a source of fiberglass/cement duplicate shingles.
Wet down the wall, and remove whole shingles from the
area in question, and cut the replacement shingles to fit.
There has never been a health complaint, of any kind or to any degree,
associated with any commercial product made of asbestos, including brake
shoes. Don't worry about it.
The cheapest way to dispose of asbestos-related material is to leave it in a
schoolyard at night. That's what Dilbert's boss did with his refrigerator.
Any other method may involve significant disposal costs in a vain attempt to
comply with science environmental regulations.
I cut asbestos board that I've been hoarding for years once in while and
see no problem doing so. The paranoid would make a production out of it
but my approach is to do it outside and I wear a small particle mask.
Dampen the material before you begin to cut and re-wet the surface as it
dries out during your work to minimize the amount of dust created.
The asbestos siding in its intact form doesn't present a hazard since
none of the asbestos fibers are free. It's the airborne asbestos fibers
that are hazardous.
I've never worked with asbestos siding but you may be able to score and
break it thus avoiding any cutting.
Thank you all for the replies. Amazing the variation in responses!
I've done some general reading on the Internet, as advised, and it
seems the stuff is encapsulated, as mentioned, and is only a problem
if by cutting or drilling the dust becomes airborn. I think we'll
take the advice of one gentleman and simply wet the area down, remove
the old siding in the area, and get replacement fiber-cement siding
for the pieces that need cut. Re-use pieces that don't need cut.
Let me know if you think I'm an idiot and will create an environmental

If you don't like the idea of trying to dampen large work areas with a
little spray bottle, call around to some garden centers and ask if they
carry a brass misting nozzle that attaches to a garden hose. It's made by
Dramm. It creates a mist which, with the water pressure adjusted correctly,
is like a thick fog. It's designed for watering tiny seeds, but it's handy
for other purposes, too.
That should do it for the dust - but what about the radioactive contamination.
I'm not kidding - I use the radiation from the cement floor to calibrate my
radiation detectors. Have you have put a box of miricle grow in front of
a gamma detector?
You may be able to throw asbestos into a landfill, but if you follow federal
regulations miracal grow must go to a low level radioactive waste disposal
site because it is significantly more radioactive than the cement in the floor.
Think about that the next time you are eating a tomato...
