OUR SERVICE TERRITORY
Northwest Indiana & South Suburban Chicago
Downing Plumbing & Heating, Inc. has been based in Merrillville, Indiana since 1950 — and from that location, we reach every community listed below. Our service territory spans the Indiana counties of Lake, Porter, and LaPorte, plus the south and southwest suburbs of Cook County and Will County in Illinois.
We hold active plumbing licenses in both Indiana and Illinois, which means we can complete all permitted work anywhere in our service area without subcontracting or delay. Whether you're in a pre-war Gary neighborhood or a newer Frankfort subdivision, you get the same licensed Downing Plumbing crew.
