What goes wrong in Boone County homes
Natural gas in most homes
79% of occupied homes here heat with utility gas, so gas water heaters, ranges and dryers are common. That means gas line extensions for new appliances, flexible connector replacements and venting checks when a water heater is swapped. If you smell gas, leave first and call the gas utility from outside. See gas line repair.
Long, hard winters
51% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Illinois winter those are the lines that freeze and split. See frozen and burst pipe repair.
Pre-1960 homes: galvanized pipe and cast iron
29% of homes in Boone County's covered ZIP codes were built before 1960, 19% of them before 1940. Houses that old often still have galvanized steel supply lines that rust closed from the inside, and cast iron or clay sewer pipe that cracks and lets roots in. Weak pressure at upstairs fixtures, brown water after a shutoff and slow drains are the usual clues. Typical fixes are whole-house repiping and a sewer camera inspection.
Hard water
Illinois water is generally hard. With 79% of homes here on gas, scale settles as sediment in gas water heater tanks, which then rumble and wear out early. See water softener installation.
