Winter Pipe Freezing Prevention Checklist for Everett and Marysville

Cold snaps in Snohomish County don't give much warning. The forecast flips, the wind picks up, and the pipes in your crawlspace or along an outside wall take the hit first. Water expands as it freezes, and that pressure is what cracks pipes, whether they're metal or plastic.

Most winter pipe freezing prevention is quick, cheap work you do before the temperature drops. This checklist covers what to check, which habits actually help, and when it's time to call a plumber in Everett, Marysville, or anywhere else in the county.

Winter Pipe Freezing Prevention: Which Pipes Freeze First

These are the spots we see freeze most often in Snohomish County homes.

• Outdoor hose bibs and sprinkler lines. They sit outside with no heat from the house, so they're usually the first to go.

• Pipes in unheated spaces. Crawlspaces, garages, and basements can drop below freezing well before the rest of the house does.

• Pipes along outside walls. Kitchen and bathroom sinks on exterior walls are a classic trouble spot.

Walk your home with that list in mind. A hose bib on the shady side of the house or a supply line crossing a cold garage deserves a closer look. If you can't tell where a line runs or whether it's insulated, a plumbing inspection is a good place to start.

Before the First Hard Freeze

• Unhook your hoses. A connected hose traps water at the spigot, and when it freezes, the pipe behind the wall can split.

• Cover your outdoor faucets. Foam faucet covers and pipe insulation are cheap and sold at any hardware store.

• Drain sprinkler and pool lines. Follow the directions from your installer or the manufacturer.

• Insulate the pipes you can reach. Foam sleeves on pipes in the garage, crawlspace, and along outside walls keep cold air from pulling heat out of the line. Pay attention to elbows, valves, and the short runs behind cabinets, since those often get missed.

If a pipe is hard to get to or sits in a space that stays cold no matter what, hand that one to us instead of crawling through a tight crawlspace in December.

During a Cold Snap

• Keep the thermostat steady. Set it to the same temperature day and night, and never below 55°F. Turning it way down at night or while you're at work is exactly what lets a pipe freeze.

• Open sink cabinets on outside walls. It lets warm air from the house reach the pipes behind them.

• Let a cold water faucet drip overnight. Moving water is much harder to freeze than still water, and a slow trickle through the line helps prevent it from freezing.

• Pay attention to your water pressure. If a faucet only trickles or nothing comes out in the morning, a pipe somewhere may already be frozen.

Heat tape can help on problem spots, but products vary a lot. Follow the manufacturer's instructions exactly and don't improvise on the wiring.

If You Leave Town

An empty house is one where nobody notices the heat went out or a pipe started leaking. Keep the thermostat at 55°F or higher while you're gone, and ask a friend or neighbor to check the house every day during a cold stretch. If nobody can check in, a smart thermostat or leak sensor that sends alerts to your phone is a good backup.

If a Pipe Freezes Anyway

No water at one fixture, low pressure across the house, or frost or a bulge on a visible pipe all point to a freeze. Shut off the water at the main right away. A split pipe often won't leak until it thaws, so turning the water off early can save you from a flood. Then call us to thaw and check the line instead of trying to force it open yourself.

Call us if a pipe is frozen and won't thaw, if you can't find the frozen section, if a line has already burst, or if the pipes that need insulation are somewhere you can't safely reach.

Frequently Asked Questions

At what temperature should I start dripping my faucets?

There's no single number for every house, since pipe location, insulation, and wind all play a part. We recommend starting a slow drip any time a hard freeze is in the forecast and leaving it on overnight, along with keeping the thermostat at 55°F or higher.

Does letting water drip really prevent pipes from freezing?

Yes. Moving water is much harder to freeze than still water. Let cold water drip from faucets on outside walls. It costs very little and shows you water is still moving through the pipes.

Should I keep my thermostat at the same temperature all day and night?

Yes, that's what we recommend in cold weather. Keep it steady and never lower than 55°F. It keeps the pipes inside your walls and under your floors warmer, which matters most during a stretch of cold nights.

Which pipes in my home are most likely to freeze?

Outdoor hose bibs and sprinkler lines top the list, followed by pipes in crawlspaces, garages, and basements, and plumbing along outside walls. Start your checks there and insulate whatever you can safely reach.
