One of Indiana's fastest-growing communities; newer 1990s–2000s homes generate active demand for fixture upgrades, water softener service, and first-time water heater replacements. Downing Plumbing has served Lake County since 1950 — licensed, insured, and locally owned.
LAKE COUNTY, INDIANA
Newer construction in St. John doesn't mean you're immune to plumbing service needs — it just means the needs are different. Homes from the 1990s and 2000s are now entering their first major service cycle: water heaters approaching the 15-to-20-year mark, water softeners that haven't been serviced in years, and sump pumps that have been running quietly since original construction. Many newer homes in the area are also candidates for tankless water heater upgrades, whole-house water filtration systems, and quality fixture replacements as homeowners update kitchens and bathrooms. Downing Plumbing serves these communities year-round with the same expertise we bring to older homes — just applied to a different generation of equipment.
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.
