Preventing Seasonal Water Damage in Indiana

Published September 15, 2026 by Indiana Water Damage Pros

Winter: when pipes freeze and split

Indiana winters swing hard. A stretch of single-digit nights followed by a 40-degree afternoon is the pattern that bursts the most pipes, because the freeze expands the water and the thaw releases it. Supply lines in exterior walls, unheated crawl spaces, garages, and attics are the most exposed.

• Insulate pipes in unheated areas with foam sleeves, paying special attention to runs along exterior walls and under floors above crawl spaces.
• During hard freezes, let one faucet fed by an exposed pipe drip slightly. Moving water freezes more slowly than still water.
• Open cabinet doors under sinks on exterior walls so room air reaches the plumbing.
• Keep the thermostat at 55 degrees or higher even when you are away, and never shut off heat to a room with plumbing in it.
• Disconnect garden hoses and shut off, then drain, the hose bib lines before the first hard freeze.
• If you leave for an extended trip, shut off the main water valve and drain the lines. A burst pipe with no water pressure behind it does almost no damage.

If a pipe does freeze, thaw it slowly with a hair dryer or space heater aimed at the pipe, starting at the end closest to the faucet. Never use an open flame, and never leave the process unattended. If the pipe has already split, shut off the main valve before thawing it.

Spring: storms, rivers, and sump pumps

Spring in Indiana brings two kinds of water at once. Heavy rain overwhelms gutters, window wells, and floor drains, while snowmelt and saturated ground push the water table up until it finds the lowest point in the house. Southern and central Indiana river towns along the Ohio, White, and Wabash rivers see this pattern every few years.

• Test the sump pump before storm season by pouring water into the pit and watching it cycle on and off. Test the float switch by lifting it by hand.
• Check for a backup power option. The storms that knock out electricity are the same storms that fill the pit.
• Clear the discharge line and confirm it empties well away from the foundation and does not freeze shut.
• Clean window well drains and make sure covers are intact.
• Consider a backwater valve on the main drain line if your basement has ever taken water from a city sewer backup.
• Keep floor drains clear and pour a little water down them monthly so the trap does not dry out and let sewer gas and odors rise.

Summer: humidity and condensate

Summer damage is slow and easy to ignore. Central air conditioners pull gallons of water out of the air every day, and that water has to go somewhere. A clogged condensate drain line or a cracked drain pan leaks into the ceiling or closet below the air handler, often for weeks before anyone notices.

• Pour a cup of water down the condensate drain line monthly, or have the system serviced before the cooling season starts.
• Inspect the drain pan under the air handler for standing water or rust.
• Keep indoor humidity between 40 and 55 percent. A cheap hygrometer tells you when the basement or crawl space is drifting upward.
• Run a dehumidifier in finished basements and crawl spaces during humid stretches rather than only after a leak.
• Watch for condensation on cold water pipes and toilet tanks, which can drip steadily onto floors.

Fall: gutters, grading, and the freeze ahead

Fall is the preparation season, and the work you do now determines how the house handles January and March.

• Clean gutters and downspouts after the leaves drop. Full gutters send water over the edge and against the foundation.
• Confirm downspouts discharge at least several feet from the foundation and that splash blocks or extensions are in place.
• Check the grading around the house. Soil should slope away from the foundation, not settle toward it.
• Inspect the roof and flashing before snow load arrives; small leaks are far cheaper to fix in October than in a thaw.
• Test the sump pump and the backwater valve one more time before the ground freezes.
• Seal cracks in basement walls and around pipe penetrations with hydraulic cement or polyurethane sealant.

A month-by-month routine

1. October: Clean gutters, check grading, drain and store hoses, shut off exterior faucets.
2. November: Insulate exposed pipes, service the furnace, test the sump pump, locate the main shutoff valve.
3. December through February: Keep heat at 55 degrees or higher, drip exposed faucets during cold snaps, and watch for frost on pipes or windows.
4. March and April: Test the sump pump again, check window wells, and clean floor drains before the heaviest rain.
5. May: Service the air conditioner and its condensate line before the first humid week.
6. June through September: Watch basement humidity, run the dehumidifier, and keep an eye on the water bill for unexplained climbs.

When prevention fails

Even a well-maintained house can lose a supply line or take on storm water. What matters then is speed. Water that is extracted and dried within the first day or two can often leave the structure intact, while water that sits for a week usually means demolished drywall and replaced flooring.

When that happens, emergency water extraction and flood damage cleanup handle standing water and contaminated material, while basement water damage work addresses sump failures and foundation seepage. Providers serving Gary, Terre Haute, and Muncie see these seasonal patterns every year, and additional preparation guidance is collected on the blog.

Ten minutes of prevention each season is usually enough to keep water out of rooms it does not belong in.
