Why Fox Valley basements get wet

After the last glacier retreated, glacial Lake Oshkosh covered much of the Fox River lowland, which stretches from Green Bay to Portage, and left behind red, clay-rich silt and clay sediment. That fine-grained soil is relatively impermeable, so water that can't soak in has to go somewhere, and sometimes that's toward a foundation. (Source: Wisconsin Geological and Natural History Survey, General Geology and Natural Resources of Winnebago County (WOFR2004-03).)

Fox Valley basement leaks often spike when rain falls on frozen ground: the water can't soak in, and frozen sump discharge lines can stop a pump from getting water out. (Source: WBAY-TV, "Basement flooding a problem after rain, snow mix in Fox Valley".)

Areas we cover

Common questions

Who will I be talking to?

Fox Valley Basement Waterproofing is a referral service. We connect you with an independent local basement waterproofing contractor who serves your area. We don't do the work ourselves.

Does it cost anything to request an estimate?

No. Requesting an estimate is free. Inspections, quotes and prices come from the contractor; get a written estimate before work starts.

Is there water in my basement right now — what should I do?

If water is near outlets, appliances or the electrical panel, stay out and don't touch anything electrical; contact your electric utility or an electrician. Otherwise, check that the sump pump is running and its discharge isn't blocked, then request a call back and mention that water is coming in now.

How do I check a contractor?

Ask for proof of insurance, a written scope and warranty terms in writing, and look up reviews yourself. Compare more than one quote for big jobs.
