What goes wrong in Kendall County homes
Newer homes on their first water heater
50% of homes here were built in 2000 or later. Those houses usually have PEX or CPVC supply lines in good shape, so the work is on equipment: original tank water heaters past their 8 to 12 year service life, expansion tanks, pressure regulators and fixtures. See water heater replacement.
Natural gas in most homes
86% 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
25% 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.
Hard water
Illinois water is generally hard. With 86% of homes here on gas, scale settles as sediment in gas water heater tanks, which then rumble and wear out early, and newer homes with tankless heaters need yearly descaling. See water softener installation.
