Most second-home owners in the Methow come up two or three weekends a winter, drop their bags, flip on the heat, and expect the place to be exactly how they left it in September. The owners whose places survive without surprises all do roughly the same things in the first week of November. The ones who don’t tend to find out the hard way in January, usually by phone, usually from a neighbor.
Here is the punch list I walk through with clients who are closing a second home before winter, in the order it actually gets done.
1. Water is the thing that breaks houses
A pipe that holds pressurized water and then freezes does not fail quietly. It splits, thaws when the house warms, and runs on the floor until someone notices. In an unoccupied cabin that can be a week. The fix is simple and non-negotiable: if the house will be below 55 degrees for any stretch, winterize the plumbing.
What that means in practice:
- Shut the main water valve.
- Drain the lines (open the lowest tap and the highest tap, let gravity work).
- Blow out the lines with compressed air if a plumber hasn’t done it for you.
- Pour non-toxic RV antifreeze into every trap: kitchen, bath, laundry, utility sink, floor drains, washing machine standpipe.
- Drain the water heater and shut the gas or breaker.
- If you have a hydronic system, leave it running on a low setback (50–55F), and have the glycol level checked.
2. Protect the well head and the pump pit
Most Methow second homes are on wells. A well head left exposed in a hard valley cold snap — the kind that drops to minus 10 for a week — will freeze a pressure switch, split a check valve, or shear a pit-less adapter. Heat tape on the above-grade pipe, insulation around the pressure tank, and a well house that actually seals are small spends that prevent a two-thousand-dollar March surprise.
3. Schedule the plowing, and schedule it with someone local
If no one is plowing your driveway, you cannot get in. If no one is plowing your driveway for the week after a 2-foot dump, your roof is holding snow it was not designed to hold alone. Get on a plow contract by early November — most of the valley’s operators have fixed-season lists that fill by Thanksgiving. Pay attention to the plowing agreement for your road association too: some plow driveways, some don’t, and most have rules about where the piles can go.
4. Watch the roof load, especially on flat sections and north faces
Modern Methow builds are engineered for serious snow — many for 70 to 100 pounds per square foot on the roof — but add-on sheds, carports, old cabin porches, and anything with a flat or low-pitch section are a different story. If you can’t check it yourself every 10 days, hire a neighbor or caretaker. A snow rake and a long handle are cheap. A collapsed porch is not.
5. Chimneys, wood stoves, and heat tape
If the stove is your backup when the power is out (and the power will go out), get it inspected before November. Chimney fires here are not rare — they are what happens when a stove was used lightly in shoulder season, left for the year, and then run hard the first cold weekend. On the electrical side, if you have heat tape anywhere, plug it in before the first freeze and verify it works, and label the plug so no one unplugs it to charge a phone.
6. Rodents
Mice will absolutely find a way into a cabin that is going to be cold and quiet for four months. In November I put traps along the sill plate inside and out, seal visible gaps with steel wool and expanding foam, and move anything soft (towels, bedding, cushions) into closed plastic bins. Pack rats are the bigger problem up above about 2,500 feet; if there’s a crawl space, check it twice.
7. Tell your insurer the house is vacant
This is the step owners skip and regret. A standard homeowner’s policy often excludes claims if the house has been unoccupied for 30 or 60 consecutive days. Pick up the phone, tell your agent the house is a vacation property with winter vacancy, and either confirm your current policy covers it or add a vacant-home endorsement. The cost is small. The exclusion is enormous.
8. Smart tools that are worth it, and the ones that aren’t
Worth it in my experience: a Wi-Fi thermostat you can watch from home, a cellular leak sensor near the water heater and under the kitchen sink, and a cellular or LTE-backed security camera at the driveway and the deck. Not worth it if you don’t have reliable internet or power: anything that requires both to be useful. The valley has power events every winter. Plan for that.
9. Who you call matters more than what you install
The most important winterization step isn’t a product. It’s having a name and number of someone who will drive out and check the house if the temperature sensor goes offline or the weather station shows minus 15 and you haven’t been up in six weeks. That might be a professional caretaker service (there are a few operating in the valley) or it might be a neighbor you keep in touch with. Both work. No one working does not.
If you are closing on a Methow second home right now
I always walk new buyers through this list in the first week after closing, especially if the previous owners used the house year-round and this is going to be a seasonal place. The transition from occupied to seasonal is where the damage happens. If you want a copy of the full checklist — the one I keep for clients, with phone numbers for local plow operators, caretakers, and insurance agents who know the valley — just reach out.
I’ve been working with Methow buyers for over 37 years. If you’re new to winter here, the goal is simple: have the house in better shape in April than it was in November. Everything on this list serves that.
