Document the condition
Note exactly where it's located, when it appeared, what the weather was doing, and any previous repairs -- a running photo log beats a verbal description.
Read the local context
Joliet is Illinois's third-largest city, with a population of 151,837 and a median housing price around $270,000, spanning neighborhoods from the East Side Historic District's 1852-1873 homes to the midcentury houses near Rock Run Preserve in Southwest Joliet. All of that housing sits inside the Des Plaines River watershed, where urban flooding typically takes the form of basement flooding and sewer backup -- a documented, ongoing concern in regional stormwater planning regardless of a home's age or neighborhood.
Ask what will be hidden
The category of water, how long it sat, what cavities it reached, electrical safety, and how porous the materials are all shape the right scope in Will County; this guide does not promise same-day or emergency availability. The written scope should explain the preparation and verification that will no longer be visible at completion.

What official local sources add
The City of Joliet enacted a Stormwater Management Ordinance to limit runoff-related risk from new development and redevelopment, and the city is the permitting authority for land-disturbing activity, requiring landowners to maintain on-site stormwater control facilities. Parts of Joliet sit within a mapped 100-year flood zone near the Des Plaines River, and the city applies floodplain-disclosure requirements in those areas. Will County separately maintains Chapter 55 (Stormwater Management) and Chapter 164 (Water Resource Ordinances) in its county code, defining floodplain, regulatory floodway, and base flood elevation for unincorporated areas alongside the city's own ordinance.
