What goes wrong in Florissant homes
1960s and 70s homes reaching end of life
48% of the housing here dates from 1960 to 1979. Original copper supply lines in those homes are now 45 to 65 years old, and cast iron drains of that age scale up inside and crack. Seized shutoff valves, pinhole leaks and recurring main-line clogs are common calls. A camera inspection shows the condition of the sewer line before anyone digs.
Natural gas in most homes
80% 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.
Winter freezes
73% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a cold Missouri winter those are the lines that freeze and split. See frozen and burst pipe repair.
Hard water
Missouri water is generally hard. With 80% 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.
