What goes wrong in Castle Rock homes
Newer homes on their first water heater
66% 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
78% 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
7% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Colorado winter those are the lines that freeze and split. See frozen and burst pipe repair.
