Spotting it
Zonolite is one brand name MDH mentions. If the granules between your joists are loose and light, treat them as possible vermiculite and keep stored boxes and foot traffic out until the sample result is in.
Vermiculite Insulation Removal in Minnetonka
Typical cost in Minnetonka
- Attic vermiculite or loose-fill, about 800 to 1,500 sq ft of attic$7,500 – $19,000+
If your attic floor is covered in light little pebbles of gold, gray or light brown, you may be looking at vermiculite. Left undisturbed, it can stay, MDH says, and removal belongs to a licensed contractor. We take it out so the insulation, air sealing or wiring you have planned can go ahead.
We clear attics in Minnetonka, Deephaven and Excelsior.
How we handle vermiculite
Leaving it in place
If no one will work in the attic or open the ceiling below, leaving the fill alone is an option MDH accepts. Plans for insulation, wiring or recessed lights change that.
Removal under containment
We cover the rooms below and seal the attic hatch from underneath before anyone touches the fill. Then hoses vacuum it into labeled bags while a negative air unit runs. Clearance air samples come before any plastic is taken down.
After the vermiculite is out
Clearing the attic opens up the next steps.
Air sealing and insulation
Bare joists let your insulation contractor seal gaps and lay new insulation evenly.
Ducts and ceilings
Wrapped ducts in the attic and the ceiling texture below are separate materials, and each needs its own sample before anyone disturbs it.
Wrapped ducts up there too? Ask about asbestos testing, or visit our front page.
