The county's biggest city, full of 90s–2000s homes
O'Fallon is the largest city in St. Charles County, and most of its growth came in the 1990s and 2000s — subdivisions along Highway K, Bryan Road, and Highway N full of homes now on their second or third water heater. If yours is the original unit, it's living on borrowed time.
We replace water heaters across O'Fallon for one flat installed price — $2,000 for a 40-gallon tank, $2,100 for a 50-gallon. That price covers the new tank, installation, the permit, and haul-away of the old unit — no hourly billing and no surprise add-ons.
Local note: O'Fallon homes commonly have the water heater in the garage or a basement utility room. A like-for-like replacement typically takes 2–4 hours start to finish.
