Around Watertown, the first hard freeze — 28 degrees or below — usually lands sometime in the first three weeks of October. Out by the airport it runs earlier; in town, a little later. Those are long-term averages, so the exact date bounces around year to year (and the trend has been running later, not earlier). But the window is now, which makes this a good weekend for the unglamorous jobs that save you from the expensive ones.
Seven of them, in roughly the order I’d do them:
1. Disconnect the hoses and shut off the outdoor faucets.
Water trapped in a hose bib freezes, expands, and bursts the pipe inside the wall — one of the most common freeze claims there is. Do it even on “frost-free” sillcocks: a connected hose traps water and defeats the whole frost-free design.
2. Drain and blow out the irrigation lines.
Standing water in sprinkler lines and heads freezes and cracks them. A fall blowout costs a fraction of spring repairs.
3. Clean the gutters and downspouts.
Debris plus freeze-thaw makes ice dams that back water up under shingles, and ice is heavy enough to damage gutters and roof edges. East of Lake Ontario, where the snow loads get serious, clogged gutters are worse than a nuisance.
4. Service the furnace or boiler and change the filter.
The EPA’s line is blunt: dirt and neglect are the number one cause of heating system failure. A pre-season checkup catches problems before the first real cold snap, not during it. If you heat with wood — plenty of North Country homes do — this is also the moment to make sure the stove is vented right and the chimney is in good shape.
5. Caulk, weatherstrip, and check the attic.
Air leaks around doors and windows can waste as much heat as leaving a window open all winter. Sealing them also keeps pipes in exterior walls warmer, which is the part people forget.
6. Test the smoke and CO detectors — and review generator safety.
Heating season is peak carbon-monoxide season. Fresh batteries, test button, and a reminder that never changes: never run a generator indoors, and never heat with the gas oven. Ice-storm outages make generator misuse a real local risk.
7. Winterize the well — and find your main water shutoff.
A lot of Jefferson County homes are on private wells, and a frozen pressure tank or exposed pipe means no water at all. Insulate the well house, wrap exposed pipes, and keep some bottled water on hand for outage days. While you’re at it, make sure everyone in the house knows where the main water shutoff is — if a pipe ever does burst, fast shutoff is what limits the damage. Heading out of town? Keep the heat at 55 or above, or drain the system.
Bonus, takes thirty seconds: reverse the ceiling fans so they push warm air down, and leave south-facing curtains open during the day for free solar heat.
Do these now and the first hard freeze becomes weather, not an emergency. For the bigger winter picture — driving, snowblowers, what to keep in the car — the Jefferson County Winter Survival Guide has you covered.
