What goes wrong in Waukesha County homes
Natural gas in most homes
77% 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.
1980s and 90s construction and polybutylene
30% of homes were built between 1980 and 1999. Polybutylene supply pipe was installed widely in US homes from about 1978 to 1995, so houses from these years are worth checking for gray plastic pipe stamped PB2110, usually visible at the water heater or under sinks. Insurers and buyers often ask about it. See polybutylene replacement.
Long, hard winters
48% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Wisconsin winter those are the lines that freeze and split. See frozen and burst pipe repair.
1960s and 70s homes reaching end of life
28% 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.
