The City of Appleton issues a Basement Foundation Repair Permit for this work, so for jobs inside the city we apply for it ourselves and keep the paperwork in order. The permit asks for the contractor's state Dwelling Contractor number, the certification Wisconsin requires before a business can pull permits on one- and two-family homes, and we call the city's Inspection Division when the job needs its inspection.
Across Northeast Wisconsin, winter frost heave, spring snowmelt, a high water table in wet seasons and clay-heavy soil all take turns pushing on footings and basement walls. That's why movement here usually comes and goes with the seasons instead of all at once. Around Appleton we see many older block and poured basements that have taken years of that cycle.
We're based in Appleton and do the same work in the cities around it, including Grand Chute and Neenah, along with many others nearby. Outside Appleton, the local office decides whether a permit is needed, so we check with them before work starts.
