Every spring, I walk into the same claims. Frozen pipe bursts. Ice dam damage. Sump pumps that died over winter. Water heaters that gave up in February. And every single time, I think the same thing: almost all of this was preventable in October.
I’m a licensed property claims adjuster in New Jersey. This is the checklist I wish every homeowner would run through on a crisp fall weekend — eight items, each one tied to a specific winter claim I see year after year. None of them take long. All of them are cheaper than a deductible.
1. Clean the gutters and downspouts
Clogged gutters dump water behind siding, into soffits, and down foundation walls — showing up in spring as interior stains that look exactly like a roof leak. Here’s the part homeowners hate hearing: damage from clogged gutters often gets flagged as maintenance neglect, which isn’t covered. A $200 gutter cleaning beats a denied $8,000 claim every time.
What to do: get the leaves and sludge out, run a hose through the downspouts, and extend them to carry water six feet from the foundation. A gutter scoop and ladder stabilizer make the DIY version faster and safer.
The claim it prevents: interior water damage wrongly blamed on the roof, plus foundation seepage.
2. Test the sump pump
Your sump pump sat idle all summer. Don’t discover it’s dead during the first spring nor’easter. Pour a bucket of water into the pit: the pump should kick on, run strong, and discharge outside — not into your septic, not back into the pit. Listen for grinding or short-cycling, both signs it’s on borrowed time. Check the outside discharge line is clear and the check valve isn’t stuck.
And consider a sump pump alarm — a ten-dollar audible alarm that screams when the water rises too high. It’s the cheapest early-warning system in your house.
The claim it prevents: spring-melt basement flooding, the single most common NJ basement claim.
3. Shut off the exterior hose bibs
The most preventable winter claim in New Jersey. A garden hose left connected traps water in the bib; the water freezes, expands, and bursts the pipe — inside the wall, where you can’t see it. Then the spring thaw arrives and water pours into your basement or crawlspace for hours before anyone notices.
What to do: disconnect every hose and store it inside. Shut off each bib’s interior valve, open the outside bib to drain, and leave it open. Snap on insulated hose bib covers for a few dollars each.
The claim it prevents: burst hose bib flooding, often discovered days later with major damage.
4. Insulate exposed pipes
Walk your basement, crawlspace, garage, and any exterior walls. Every foot of uninsulated water pipe in an unheated space is a burst waiting for a cold snap. NJ’s polar-vortex weeks — single digits for days — are when uninsulated crawlspace pipes let go, usually at 3 AM.
What to do: foam pipe insulation sleeves are pre-slit, cost almost nothing, and go on in minutes with no tools — prioritize pipes along exterior walls and in unheated garages.
The claim it prevents: frozen pipe bursts, the winter claim I see most often, averaging five figures when it’s an upstairs bathroom pipe.
5. Check the roof before the snow load arrives
Winter finds every weakness in a roof. With binoculars, look for missing, cracked, or curling shingles; damaged flashing around chimneys, vents, and skylights; and gutter sag suggesting fascia damage. In the attic, check for daylight through the roof boards and water staining on the decking’s underside.
Knowing about a problem in October means a roofer can fix it in October; discovering it in February means water pouring in during an ice storm and emergency work at emergency prices.
The claim it prevents: winter roof leaks and the interior damage cascade that follows.
6. Deal with ice dams before they form
The NJ classic. Heat escaping into the attic melts the bottom layer of roof snow; the meltwater refreezes at the cold eaves, building a dam — and then pools behind it and backs up under the shingles, into your attic and down your walls. I’ve seen ice dams cause $20,000 in interior damage on houses with perfectly good roofs.
The real fix is attic insulation and ventilation; fall is the time to get it quoted. In the meantime, a roof rake pulls snow off the lower roof after storms and prevents the dam from forming.
The claim it prevents: ice dam interior water damage, the signature NJ winter claim.
7. Service the water heater
Water heaters don’t die gracefully — they rupture, usually in winter when sediment and corrosion are at their worst. Check the manufacture date: 10 to 12 years is the typical lifespan, and anything past that is living on luck. Look for rust at the base, moisture around fittings, and rumbling during heating (sediment cooking at the bottom of the tank).
Test the T&P relief valve: lift the lever briefly and let it snap back. If nothing comes out or it drips afterward, replace it — it’s a critical safety device. If yours sits near finished space, put a leak detector next to it — a failed 50-gallon tank releases 50 gallons fast.
The claim it prevents: catastrophic water heater failure flooding, especially brutal in finished basements.
8. Locate your main water shutoff — and make sure everyone knows where it is
This one costs nothing and takes five minutes, and it might be the highest-value item on this list. In a burst-pipe emergency, minutes spent hunting for the shutoff while water pours through your ceiling are the most expensive of the claim.
Find it now — basement near the front foundation wall, a utility closet, or outside by the meter. Tag it, show every adult in the house, and test that it turns (seized gate valves should be replaced with ball valves before winter). Some of my fastest, cheapest claims are the ones where the homeowner killed the water in under two minutes.
The claim it prevents: every water claim, made smaller. Time is damage, and this buys you time.
Do it on one October weekend
None of these takes more than an hour; most take fifteen minutes. Block out a Saturday and you’ll head into winter knowing you’ve eliminated the causes behind most of the water claims I see every spring.
