Where we dispatch, and what changes from one part of the metro to the next

Nine regions, because the plumbing genuinely differs

Grouping 216 communities into regions is not a marketing convenience. The Chicago metropolitan area contains, within about sixty miles, combined sewers and separated ones, water hardness ranging from moderate to severe, housing built anywhere between the 1880s and last year, and a frost line that behaves differently over a plowed street than over a snow-covered lawn. A plumber who knows which of those they are walking into starts the job ahead.

Three differences do most of the work. Sewer type determines whether heavy rain is a plumbing risk at all, in combined-sewer neighbourhoods a summer storm can surcharge the public main and push water back toward buildings with no backflow protection, which simply does not happen on a separated system. Housing vintage determines the materials: galvanized supply and cast iron drain in the pre-war core, copper and PVC in the post-war ring, PEX in the newest subdivisions, each failing in its own characteristic way. Water chemistry determines what wears out first, and hardness across the western and northwestern counties is high enough to measurably shorten water heater life.

How coverage actually works

The footprint is the seven counties of the Chicago metropolitan area (Cook, DuPage, Lake, Will, Kane, McHenry and Kendall), plus a short list of outlying Illinois markets: Rockford and Winnebago County, Sycamore, LaSalle, Kankakee, the Quad Cities and Carbondale. The seven metro counties are covered comprehensively; the outlying markets are a deliberate short list rather than a claim to blanket downstate coverage.

Crews are assigned regionally rather than dispatched centrally, so response times vary across the footprint and are quoted honestly rather than optimistically. Inner-ring communities see the shortest windows. The outlying markets at the edge of the list are covered, but an overnight call there during a regional weather event is a genuinely different promise, and it gets described as one.

Individual community pages are being published region by region. Until yours is live, the phone covers the same ground faster.
