Most water damage in Ohio homes traces back to a handful of predictable causes: pipes that freeze because a home got too cold, gutters that stayed clogged until water found its way into the foundation, a sump pump that hadn't been tested since it was installed, and supply lines or a water heater that ran years past when they should've been replaced. Water damage and freezing account for roughly 22.6% of all homeowners insurance claims nationally, making it the second most common cause after wind and hail. None of the tasks below take more than an afternoon, and doing them on a seasonal schedule is the most realistic way to avoid becoming part of that statistic.
Fall: Get Ready Before the First Freeze
- Disconnect and drain garden hoses, and shut off the interior valve to outdoor spigots, then open the outdoor bib to drain any water left in the line. The American Red Cross specifically calls this out in its frozen-pipe guidance, since water trapped in an exterior line is exactly what splits a pipe once temperatures drop.
- Clean gutters and downspouts at least once now, ideally twice a year total. Clogged gutters force water down the siding instead of away from the house, which raises pressure against the foundation and is a real, if slow-building, cause of basement water intrusion. Make sure downspouts discharge at least 10 feet from the foundation, not right against it.
- Walk the roofline and look for obviously damaged or missing shingles before winter weather makes repairs harder and more urgent. This is standard, sensible practice even though it isn't backed by a specific statistic from any single named authority.
Winter: Keep the Cold Outside the Pipes
- Keep the thermostat at a consistent temperature, day and night, and never below 55°F, per the Red Cross's guidance, especially important if you'll be away from the house for any stretch during a cold snap.
- Let faucets served by exposed or vulnerable pipes drip slightly during extreme cold. Moving water resists freezing far better than standing water, which is why this small step works.
- Insulate exposed pipes in unheated basements, crawl spaces, attics, and garages with pipe sleeves or heat tape. Even a simple wrap adds meaningful protection against a hard freeze.
Spring: Test What Winter Might Have Stressed
- Test your sump pump by pouring a bucket of water into the basin and confirming it activates and drains properly. Sump pumps typically last around 10 years, so start budgeting for replacement around year 7 rather than discovering a failed pump during the next heavy storm.
- Check your water heater for rust-colored water, any moisture at the base, or a popping and rumbling sound, which usually means sediment buildup. Tank water heaters typically last 8 to 12 years; tankless units 15 to 20 years or more. Past year 10 on a tank unit, treat any of those signs as a reason to replace rather than wait.
- Inspect your foundation for any new cracks that might have opened up from winter freeze-thaw cycles.
- Check washing machine supply lines for bulging, rust, or fraying, and replace on sight rather than waiting for a clear failure.
Summer: Catch What Only Shows Up Under Load
- Inspect irrigation or sprinkler systems for leaks at the heads or buried lines, which are easy to miss since the water just seems to disappear into the lawn.
- Check exterior grading around the foundation, confirming the ground still slopes away from the house rather than toward it, since soil can settle and shift over time.
- Test your sump pump's backup battery if it has one, since summer storms are exactly when a power outage and heavy rain are most likely to hit at the same time.
Year-Round: Replace Before It Fails, Not After
| Component | Typical Lifespan / Replacement Interval |
|---|---|
| Supply lines (toilet, sink, washer) | Every 3–5 years |
| Sump pump | ~10 years (plan by year 7) |
| Tank water heater | 8–12 years |
| Tankless water heater | 15–20+ years |
It's reasonable to expect that replacing these components on a schedule, rather than waiting for a failure, lowers your odds of a major claim, though no insurance industry body has published a specific figure quantifying exactly how much. What is well documented is the underlying risk: water damage and freezing caused about 22.6% of homeowners insurance claims in 2023, with an average claim severity around $15,400, according to the Insurance Information Institute.

If Something Still Gets Through
Even solid maintenance doesn't eliminate risk entirely, especially with Ohio's freeze-thaw winters and increasingly heavy summer storms. If you do end up with water damage despite doing everything on this list, see ClearFlow's guide on the first 24 hours after water damage for what actually matters most in those early hours. And if the recurring problem is specifically a basement that keeps taking on water, this checklist's maintenance items are only part of the picture — see ClearFlow's guide on basement waterproofing vs. water damage restoration for when a permanent drainage fix, not just maintenance, is the actual answer.

What temperature should I keep my thermostat at in winter to prevent frozen pipes?
The American Red Cross recommends keeping your thermostat at a consistent temperature day and night, and never letting it drop below 55°F, especially if the home will be unoccupied for any stretch of time during cold weather.
How often should I test my sump pump?
Testing it in spring, before the heaviest rain season, is common practice: pour a bucket of water into the sump basin and confirm the pump activates and drains it properly. Sump pumps typically last about 10 years, so start planning for replacement around year 7 rather than waiting for a failure during a storm.
How often should supply lines and water heaters be replaced preventively?
Supply lines are commonly recommended for replacement every 3 to 5 years regardless of material. Tank water heaters typically last 8 to 12 years, and tankless units 15 to 20 years or more; signs like rust-colored water, a leak at the base, or a popping or rumbling sound from sediment buildup mean it's time to replace rather than wait.
Why do clogged gutters cause water damage?
Clogged gutters force water down the siding instead of away from the house, letting it pool against the foundation. That raises hydrostatic pressure against the foundation walls, which can lead to cracks and basement water intrusion over time. Cleaning gutters at least twice a year, with downspouts discharging at least 10 feet from the house, helps prevent this.
Does regular maintenance actually reduce the chance of a water damage claim?
It's reasonable to expect that catching problems like a worn supply line or an aging sump pump before they fail reduces risk, but no insurance industry body publishes a specific statistic quantifying how much maintenance lowers claim frequency. Water damage and freezing caused about 22.6% of homeowners insurance claims in 2023, so the risk itself is well documented even if the maintenance offset isn't.
