Restoration firms for drying and mould removal.
Appleton sits on the Fox River, and the NOAA gauge there marks flood stages from an action level of 7 ft up to major flooding at 10.5 ft. The river has a history of winter trouble too: in 1912 an ice jam flooded the city's electric power plant in temperatures far below zero. For you, that means water can arrive from the river, from melting snow or from a backed-up drain, and the source shapes the drying and mould work. Before you hire, check how your insurance treats it. Wisconsin's insurance commissioner says most homeowners policies do not cover flooding or seepage through the foundation, and sewer backup or sump pump overflow needs a special endorsement. Ask any trade to name the source of the water in writing, list what will be dried, removed and tested, and say how moisture readings will be recorded. Keep that paperwork for your insurer. If you rent, a complaint route exists through the state if a landlord leaves a mould problem unfixed.

On January 10, 1912, an ice jam on the Fox River flooded the electric power plant in Appleton. The city was without electricity while 100 men worked to clear the jam, in a temperature of 22 degrees below zero.
Green Bay, in the Appleton metro area, averages 55.6 inches of snow per year, based on the 1991–2020 climate normals.

Ask how fast they will start drying: Health Canada says a home dried within 48 hours is less likely to grow mould.
Health Canada suggests professional help for extensive mould, meaning a patch larger than 3 m².

It depends on the cause. Wisconsin's insurance commissioner says most homeowners policies do not cover flooding or seepage through the foundation, which needs a separate National Flood Insurance Program policy. Sewer backup or sump pump overflow needs a special endorsement. Read your policy and call your insurer before work starts.

Ask for the scope in writing: the source of the water, which rooms and materials will be dried or removed, how moisture will be measured, and how mould will be contained. It should also show who does the work, the timeline, and what happens if more damage turns up behind walls.
Compare like with like. Check that each quote covers the same areas, the same drying and removal steps, and the same follow-up readings. A quote that is much shorter may leave out work. Ask each company for proof of insurance and for references you can call.
In Wisconsin, a tenant whose landlord has not fixed a confirmed mold and moisture problem may file a complaint with the Department of Agriculture, Trade and Consumer Protection (DATCP). Keep photos, dates and written messages to your landlord, since they support the complaint. Wisconsin Department of Health Services (source, opens in a new tab)
