The $9,000 Mistake Homeowners Make Every Time They Leave for the Weekend and Never See Coming
Water damage remains one of the costliest and most common home insurance problems in the U.S. For homeowners heading out for a 2- or 3-day weekend, the mistake experts keep flagging is leaving the water on in an empty house.
The event
The Insurance Information Institute has repeatedly identified water damage and freezing as a leading source of homeowners insurance losses, and the Insurance Institute for Business & Home Safety has said a supply hose can release hundreds of gallons of water in as little as 1 day if it fails while a home is empty. The specific mistake is simple: homeowners leave for 48 to 72 hours without shutting off the main water supply or checking appliance lines.
Restoration industry estimates help explain the dollar figure. HomeAdvisor has reported national water-damage repair costs commonly range from about $1,300 to more than $5,600, while more severe cleanup involving flooring, drywall, cabinetry, and mold can rise far higher. A multi-room leak that runs all weekend can easily push total repairs near $9,000 once mitigation, demolition, drying equipment, and rebuild work are added.
The local impact
The risk is not limited to one state, but it shows up differently by region. In Texas and Florida, slab leaks, water heater failures, and storm-related power outages can leave homes vulnerable when owners are gone for a long weekend, according to insurers and restoration contractors that operate in both states. In colder states such as Illinois or Pennsylvania, a winter departure can also raise the risk of frozen pipes if heat settings drop too low.
What is confirmed is that unattended leaks often get worse with time. The longer water runs, the more likely it is to soak subflooring, baseboards, insulation, and adjacent rooms. No national insurer has released a single public figure showing how many weekend-trip losses happen each year, so the exact share tied only to short absences is not publicly broken out.
The cause or context
The main cause is not usually a dramatic burst pipe. Industry groups including IBHS have long pointed to ordinary failure points such as washing machine hoses, refrigerator ice-maker lines, water heaters, dishwashers, and bathroom supply valves. Those parts are inexpensive compared with the damage they can cause, and many fail after years of wear rather than during a major storm.
For residents, the takeaway is practical. If a trip means the house will sit empty for 2 or 3 days, insurance and mitigation professionals often recommend shutting off the main water valve, keeping indoor temperatures at safe levels, and replacing aging braided or rubber hoses before they fail. Many insurers also offer discounts or underwriting credits for leak-detection devices and automatic shutoff systems, a sign that the industry sees preventable water loss as a year-round risk.
