What goes wrong in Longmont homes

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.

Newer homes on their first water heater

39% 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.

Long, hard winters

33% 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.
