Frozen Pipes: Winter’s Biggest Claim Comes With Homework Attached

By The NMH Agency Team, Licensed Agent

Every hard freeze produces the same grim harvest: supply lines burst
in attics and crawl spaces, and homes flood from the inside, thousands
of gallons before anyone notices. Freeze-and-burst events are among the
most expensive ordinary claims in homeowners insurance, routinely
running $15,000 to $50,000 once flooring, drywall, and contents are
counted. The coverage news is mostly good. The fine print, though,
contains an actual homework assignment, and homeowners who skip it can
find winter’s biggest claim declined. Let’s do the assignment.

Covered, if

Water damage from a burst pipe is a classic sudden and
accidental event: covered under standard homeowners policies,
and generously, including tear-out to reach the pipe, drying, and
repairs to everything the water ruined (the pipe itself, as usual, is
your plumber’s bill). So far, simple.

Now the condition. Most policies limit or exclude freeze damage
if the home was vacant, unoccupied, or being constructed and you
failed to either maintain heat or shut off the water and drain the
system. Read that twice, because it’s the whole game for three
groups of people: snowbirds, owners of empty or for-sale houses, and
anyone who travels in winter. Leave for two months with the heat off and
the lines full, and the resulting ice sculpture in your wall may be
entirely your bill. The policy told you the two acceptable choices: heat
on, or water off and drained. Do one, provably.

“Provably” is doing quiet work in that sentence. After a freeze loss
in an empty house, adjusters ask about thermostat settings, utility
records, and who was checking the property. Smart-thermostat logs, a
neighbor’s documented weekly walk-through, or a winterization receipt
from a plumber turn a contested claim into a smooth one. If a property
you’re responsible for sits empty in winter (a subject our vacant-home
article covers broadly), the freeze condition is the sharpest edge on
it.

The occupied-home version

For the house you actually live in, coverage is friendlier, and the
failure mode is different: it’s the pipe nobody thought about. The
claims cluster in predictable anatomy: supply lines in exterior walls
(especially kitchen and bathroom plumbing on north-facing walls), attics
and crawl spaces where lines run outside the heated envelope, garage
ceilings below bonus rooms, and hose bibs with hoses still attached
(trapped water freezes back into the wall). Regional note: freeze claims
spike hardest not in the coldest states but in the occasionally
cold ones, where plumbing was built casually about cold and a Texas- or
Tennessee-style polar snap finds every shortcut at once.

The prevention list is famously cheap against a five-figure claim:
foam pipe insulation on vulnerable runs ($20), disconnected hoses and
insulated bib covers ($10), cabinet doors open and faucets dripping on
brutal nights (free; moving water resists freezing and a drip relieves
pressure), heat no lower than about 55 even when away, and heat tape on
known problem runs. Know where your main shutoff is
before you need it, because when a pipe does let go, minutes of flow
equal thousands of dollars.

Leak-detection tech deserves its own sentence: water
sensors under sinks and near the water heater cost $30 to $50, and
whole-home automatic shutoff valves detect abnormal flow and close the
main. Carriers increasingly discount for them, and among our customers
who’ve had one trigger, the gadget-to-averted-claim ratio is the best in
home ownership.

If it happens anyway

Shut off the main, kill electricity to affected areas if water is
anywhere near it, and start drying immediately: fans, dehumidifiers,
professional mitigation for anything beyond a small area, because mold
complicates everything after 24 to 48 hours and policies expect you to
prevent further damage (keep every receipt; that work is reimbursable).
Photograph before cleanup. Report the claim same-day. And thaw any
frozen-but-not-yet-burst lines gently: hair dryer and patience, never a
torch, which trades a plumbing claim for a fire claim in one dramatic
gesture.

The one-paragraph version for your refrigerator: heat on or water
drained when away, hoses off in October, insulation on the ugly runs,
sensors by the heater, and the shutoff location taught to everyone tall
enough to reach it. Winter’s biggest claim is also its most preventable,
and the policy pays best for the household that did its homework.
