What goes wrong in Franklin County homes
Natural gas in most homes
67% 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
50% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Ohio winter those are the lines that freeze and split. See frozen and burst pipe repair.
Hard water
Ohio water is generally hard. With 67% 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.
