Hello RS'ers... been on here nearly 10 years and haven't once noticed this sub forum.
We bought an older farm house in the country - built in 1960.
Due to the age, we've had a few materials tested for asbestos.
Ceiling tiles: negative.
Drywall/mudding: 1-5 % of mudding (will take appropriate measures)
Now the attic has vermiculite insulation. We took one sample (obtained according to recommended procedures) and had it tested. The results were negative.
Now, after a fair amount of reading online, I'm of the understanding that the testing of vermiculite can't be completely trusted for accuracy (stories of 3 samples being taken and only one coming up positive). In some places, vermiculite is considered hazardous, despite any testing, as almost all forms of it contained asbestos.
The attic area is approx. 1200 sq ft and fairly open/accessible. We've received quotes between $7000 and $16,000 and a 5 day process to have it removed. I understand it's not an issue if it's not disturbed, however we have renovation plans that will absolutely disturb it - plus its R value is pretty weak.
Has anyone gone down this road, specifically with vermiculite?
TIA
