Water damage is not always caused by storms or flooding. In fact, many of the most common and costly incidents come from inside the home in the form of leaky pipes, broken appliances or clogged HVAC lines. The good news? Most of these are preventable.
 
Taking simple steps to prevent water damage—like inspecting appliances and installing leak detectors—can save you thousands in repairs and insurance claims. And if damage does occur, knowing how to respond quickly and correctly helps protect your home, your belongings and your peace of mind.
 
Here’s how you can stay ahead of non-weather water damage with smart habits, simple tools and some planning.

A Deep Dive on Water Non-Weather Damage

Water non-weather damage is exactly what it sounds like. It’s usually caused by:
 
  • Plumbing leaks (under sinks, behind walls)
  • Appliance failures (washing machines, water heaters)
  • HVAC issues (clogged condensate lines)
  • Sewer backups and sump pump failures
Non-weather water damage can lead to thousands of dollars in repair costs, temporary displacement, and long-term property devaluation for homeowners. For insurers, water damage events can lead to increased claim activity and resource demands, which is why prevention and early action are so important—for everyone’s peace of mind and protection.

Non-Weather Water Damage Prevention Tips That Work

  • Inspect regularly – check under sinks, around toilets and behind appliances, including refrigerator supply lines and icemaker water lines
  • Upgrade smart – install leak detectors and automatic shut-off valves
  • Maintain seasonally – winterize pipes, disconnect outdoor hoses and keep your thermostat at safe temperatures when away
  • Use tech – smart home tools like leak alarms and cameras can alert you early
  • Plan ahead – use a home maintenance calendar or subscribe to a service plan for routine HVAC and plumbing checks
Print this checklist and keep it somewhere handy, like on your fridge or in your garage, for more frequent reminders.

Resources for Home Safety Checks

Homeowners may not realize that some local fire departments offer community outreach programs that include home safety visits, especially for older adults or high-risk households. Check your city or county fire department’s website.
 

Proactive Inspections and Repairs

Hiring a contractor for inspections and preventative maintenance can help prevent costly mistakes and ensure your home is safe and secure.
When hiring a contractor, be sure to:
 
  • Always verify that the contractor is licensed and carries liability and workers’ compensation insurance.
  • Ask for recent client references and check online reviews; look for consistent feedback on reliability and quality.
  • Get at least three written estimates and compare scope, materials and timelines—not just price.
  • Ensure everything is in writing, including payment schedules, materials, timelines and warranty terms.
  • Choose contractors familiar with local building codes and who have a reputation in your community.

What To Do If a Non-Weather Water Event Occurs

If you spot water damage in your home:
 
  1. Shut off water (and electricity if needed).
  2. Save the broken part/s (for insurance or subrogation).
  3. Document everything. Detailed documentation helps your adjuster understand the full scope of the damage and may speed up your claim. Be sure to take clear photos and videos of:
    1. The source of the leak (e.g., burst pipe, failed appliance)
    2. All visible damage (floors, walls, furniture)
    3. Any cleanup or emergency repairs
      1. Also gather receipts for emergency services and any original purchase or installation info for the failed item
  4. Call your insurance provider right away. When water damage strikes, time is critical—not just to stop the damage, but to ensure your insurance claim is smooth and successful. The sooner you report the incident, the sooner you’ll begin to receive help.
    1. Waiting to get ahead of the situation can lead to:
      • Worsening damage that could have been prevented
      • Missed opportunities for emergency mitigation
      • Denied or reduced claims
    2. Tip: Save your insurer’s claim contact info in your phone and keep a printed copy in an emergency binder/notebook.
  5. Avoid repairs until an adjuster has inspected the damage.

Emergency Mitigation Services (EMS)

The Hartford has preferred contracts with EMS companies and can make referrals for you. EMS professionals specialize in drying out homes and preventing mold, which is essential for a safe and thorough recovery. Typically, they will perform the following activities based on the damage:
 
  • Use industrial fans and dehumidifiers
  • Remove wet flooring or drywall
  • Monitor moisture levels

Avoiding Common Non-Weather Water Damage Mistakes

Costly errors can sometimes be made in the immediate aftermath of a water event.
✘ Don’t:
  • Delay your response. Waiting even a few hours can lead to:
    • Mold growth
    • Structural damage
    • Denied claims due to “neglect”
  • Throw away damaged parts. A broken hose or cracked valve might be key to your claim; or even a subrogation case where your insurer recovers costs from the manufacturer.
  • Make repairs before inspection. Fixing things too soon can erase evidence and complicate your claim.
✔ Do: 
  • Shut off the water, document the damage and call your insurer right away.
  • Save all damaged components in a labeled bag or box until your adjuster says it’s okay to discard them.
  • Make only emergency repairs (like stopping active leaks) and wait for your adjuster to inspect the damage before starting full repairs.
 
With the right habits and tools, you’re not just preventing damage—you’re protecting your home and your peace of mind. Staying proactive and prepared will help you stay in control.
