Winter storm readiness
Annual · typically November · weather can move it up
Why it matters
With ~60–120 freeze days a year in your county, winter isn't a surprise — but the FIRST hard freeze each season is still the one that does the damage, because it finds whatever changed since last year: the hose left on, the crawlspace vent knocked open, the cabinet remodel that put a sink pipe against an exterior wall.
Water expands about 9% when it freezes, and a closed pipe has nowhere to send that pressure. The physics is boring and undefeated. Everything below is about giving the water somewhere to go, keeping heat where pipes are, or getting the water out of harm's way entirely.
We'll send a hard-freeze alert when a serious cold snap enters your forecast — that alert means run the quick version of this list tonight.
What skipping it costs
$1,000–$20,000
A pipe freezes, splits, and thaws — and the thaw is when the flood starts, often inside a wall while everyone's at work. Insurance industry data puts the average frozen-pipe claim north of $10,000. The prevention is foam tubes, open cabinet doors, and a dripping faucet: maybe $40 all-in, and one evening.
Two ways to get it done
Do it yourself
You'll need: Utility knife, Tape measure, Flashlights + batteries (this task doubles as your check on them), Foam pipe insulation for exposed runs (~$1.50/6ft), Foam faucet covers, Weatherstripping as needed.
The November setup (once):
- Foam-tube every exposed pipe run you can reach.
- Foam covers on outdoor faucets (hoses already disconnected — that's its own task and it matters more than the cover).
- Find and label your main water shutoff if you haven't — it's this app's first task for a reason, and a freeze event is when you'll want it in muscle memory.
- Locate which sinks sit on exterior walls. Those are your cabinet-door sinks (below).
The cold-snap drill (each hard freeze):
- Open cabinet doors under exterior-wall sinks — room heat is the pipe's only friend inside that cabinet.
- Set a pencil-thin cold drip at the farthest exterior-wall faucet. Moving water resists freezing, and it relieves pressure if ice forms anyway. The water bill cost is pennies.
- Keep the thermostat at normal overnight — the "economize at night" habit is how 2 a.m. becomes the freeze hour. Leaving town? 60°F minimum, never off.
- Generator or space heaters in the plan? The rule that keeps families alive every ice storm: generators run OUTSIDE, 20+ feet from windows, period. Carbon monoxide kills more people in outages than the cold does. (Your CO detectors got tested in this app's safety task — this is why.)
Hire it out
$150–$400National fair range — local labor moves this number.
A plumber's winterization visit — insulating the awkward runs, thermostatic heat tape where it's warranted, shutoff check — runs $150–$400 and is a genuinely good buy for crawlspace houses and anyone who travels in winter. Book it in October; the same work during a cold snap costs emergency rates.
If a pipe does freeze despite everything: shut the water at the main, open the affected faucet, and warm the pipe gently (hair dryer, heat lamp at a distance) — never a torch, never a heat gun against framing. No water anywhere in the house during a freeze usually means the main line froze — that's a pro call, but shut the main anyway so the thaw doesn't become the flood.
Ask the tech
- Which pipe runs in this house are the freeze risks, and did you insulate all of them or just the easy ones?
- Where's my main shutoff, and does it work? Test it while you're here.
- Is heat tape appropriate anywhere here, and is what you're installing thermostatically controlled?
Red flags you're being upsold
- Whole-house repipe or 'pipe relocation' pitches from a freeze-prep visit. Insulation, heat tape, and air sealing solve nearly every residential freeze risk for hundreds, not thousands.
- Non-thermostatic heat tape, or heat tape laid over its own insulation against the maker's instructions — that's how the fix becomes the fire.
- Emergency-pricing 'winterization specials' sold during the cold snap itself. This work costs half as much in October.
The call
DIY the whole checklist — none of it is skilled work. The one hire-out: if you have long pipe runs in a vented crawlspace, pay a plumber once to insulate them properly and you're set for a decade.
