Frozen Pipes: What to Do During an Everett Cold Snap

What to do if you suspect a frozen pipe

If a faucet suddenly gives you no water, or just a trickle, when the rest of the house still has pressure, and it is cold outside, a frozen pipe is the likely cause. First, leave that faucet open a little. Even a thin stream helps relieve pressure in the line as the ice begins to thaw, and it gives you an early sign of when water starts moving again.

Next, find where the affected line runs and try to identify the coldest section along its path, since that is usually where the freeze is. Apply gentle, even heat to that section using one of the safe methods below. Do not use an open flame anywhere near a pipe, whether it is copper, PEX, or anything else. A blowtorch can scorch nearby framing, damage the pipe itself, or in the worst case start a fire inside a wall or crawlspace. If the pipe has already split, the fix moves from thawing to water line replacement for that section.

Where pipes freeze in Everett homes

Everett gets a few freezing nights most winters and, less often, a multi-day cold snap that catches houses off guard because it is not the norm here. The pipes that freeze first are almost always the ones with the least protection from the cold: supply lines running through a crawlspace, especially near a vent or an uninsulated section, pipes inside exterior walls that lack adequate insulation, lines in an unheated garage, and hose bibs on the outside of the house that were not shut off and drained before the cold arrived.

Homes with polybutylene supply pipe, common in construction from roughly 1978 to 1995, are not more prone to freezing specifically, but any older or partially updated plumbing system tends to have more of these exposed, under-insulated runs than a newer build.

Safe ways to thaw a frozen pipe

Work from the faucet end of the frozen section back toward the coldest point, not the other way around. This lets melting ice and steam escape through the open faucet instead of building pressure between two blocked points, which is part of how pipes burst in the first place.

If you cannot find where the pipe is frozen, if it is in a wall you cannot access, or if the low flow has not returned after a reasonable effort at thawing, stop and call a plumber rather than opening up finished walls yourself.

• A hair dryer on a low or medium setting, moved back and forth along the frozen section rather than held in one spot
• Towels soaked in hot water and wrapped around the pipe, reheated as they cool
• An electric heating pad or heat tape rated for plumbing use, wrapped according to its instructions
• Raising the ambient temperature in the space, such as a space heater placed safely away from anything flammable in a garage or crawlspace

Signs a pipe has already burst

A pipe does not have to be actively dripping for you to suspect a burst. Watch for water stains spreading on a ceiling or wall, a damp or soft spot on flooring near where a line runs, the sound of running water when nothing is turned on, or a noticeable drop in water pressure once the ice around a break starts to melt and water begins escaping instead of reaching the faucet.

If you see or hear any of that, shut off the main water valve immediately, even if you are not sure exactly where the break is. It is far better to be without water for a day than to let a burst pipe keep flowing into a wall or ceiling while you investigate. Once the water is off, this becomes an emergency plumber call rather than something to sit with overnight.

Preventing frozen pipes before the next cold snap

Insulating exposed pipe in a crawlspace, garage, or exterior wall is the single most effective step, and foam pipe sleeves from a hardware store cover most of what a homeowner can reach without opening walls. Insulated faucet covers for exterior hose bibs are inexpensive and take minutes to install each fall, and disconnecting garden hoses before the first freeze matters just as much, since a hose left attached traps water in the bib itself.

Crawlspace vents are worth a second look too. Some homeowners close foundation vents during winter to keep cold air out, which can help, but make sure any crawlspace insulation and vapor barrier is intact first, since a poorly insulated crawlspace with closed vents can trap dampness that causes its own problems.

During an actual hard freeze, letting a faucet drip slightly on the coldest nights, particularly one fed by a line you know runs through a crawlspace or exterior wall, keeps water moving just enough to resist freezing. It is a small step that costs almost nothing and prevents a lot of hassle.

After the thaw: what to check

Once temperatures rise and pipes fully thaw, run water at every fixture briefly and watch for leaks you did not notice during the freeze itself, since a hairline crack from expanding ice sometimes only shows up under full pressure once everything melts. Check under sinks, around the water heater, and in the crawlspace if you can access it safely. Catching a slow leak from a stressed pipe now costs far less than dealing with the damage a few weeks later.
