Former rail hub in south Cook County; significant pre-war housing inventory throughout means clay tile sewers and galvanized supply pipe are standard in most residential blocks. Downing Plumbing has served Cook County since 1950 — licensed, insured, and locally owned.
COOK COUNTY, ILLINOIS
Homes built before 1950 carry plumbing infrastructure that was never designed to last this long. In Chicago Heights, that typically means galvanized steel supply pipes that have been corroding from the inside for 70-plus years, clay tile sewer lines that have cracked and shifted over decades of freeze-thaw cycles, and cast iron drain systems loaded with decades of scale and buildup. Many pre-war homes in the area also retain lead service lines connecting the water main at the street to the meter inside — a public health concern that can go undetected for years. Downing Plumbing has extensive experience working with older plumbing systems throughout the region and can assess, repair, or systematically replace aging infrastructure the right way.
Downing Plumbing & Heating, Inc. has been the trusted plumber for Northwest Indiana and south suburban Chicago since 1950. We're locally owned, licensed in both Indiana and Illinois, and our trucks run out of Merrillville — within reach of every community we serve.
