Insulation Removal in Oshkosh, WI

Insulation removal is needed less often than people think, but when it is needed, there is no shortcut. Dry, clean attic insulation can stay; we seal around it and add more. Insulation that has been soaked by a roof leak or flood water, has mold growing in it, is full of rodent droppings or is so deep we cannot reach the ceiling leaks under it has to come out.

After the 2026 flooding

The National Weather Service office in Green Bay reported prolonged flooding on the west and north sides of Lake Winnebago in April 2026 and record Wolf River crests upstream. Basements and crawl spaces that took on water may still have wet insulation in rim joists, walls or floor framing. Wet fiberglass and cellulose do not dry well in place and can hold moisture against wood, so we remove it and let the framing dry before reinsulating.

How removal works

In attics we run a large vacuum hose from a collection unit outside, so loose fill goes straight into bags. Batts are bagged by hand. Then we seal every bypass and put in new insulation.

Vermiculite and old foam

Vermiculite, a pebbly gray-brown fill in some older attics, can contain asbestos. We do not disturb it; we recommend testing and, if needed, an abatement contractor. Spray foam that has to go is cut and scraped out, which takes more time than vacuuming.
