Freeze Watch for Western Loudoun: Protecting Your Outdoor Plumbing This Weekend

The National Weather Service has issued a Freeze Watch that includes Western Loudoun County, according to the NWS Baltimore/Washington office. The watch also covers several Maryland counties: Carroll, Frederick, Northern Baltimore, and Northwest Harford. The forecast calls for sub-freezing temperatures in the upper 20s and low 30s from late Saturday night through Sunday morning.

The NWS notes that the frost and freeze could kill crops and sensitive vegetation, and could possibly damage unprotected outdoor plumbing. That last part is our department.

What a Freeze Watch means for your home

A watch means freezing conditions are possible, not guaranteed. It's an early heads-up, and it's the right moment to spend a few minutes outside rather than scrambling at midnight.

The pipes most at risk this weekend are the ones exposed to open air:

• Outdoor hose bibs (spigots) on the front, back, or side of the house
• Hoses left connected, which can trap water against the spigot
• Irrigation lines and sprinkler components above ground
• Pipes in unheated spaces like garages, crawl spaces, and exterior-wall cabinets

Water expands as it freezes, and that pressure can crack a pipe or fitting. The damage often doesn't show until the pipe thaws and starts leaking, sometimes inside a wall or ceiling. For more on how that happens, see our overview of frozen pipes in Northern Virginia.

Simple precautions before Saturday night

Keep it to the basics:

• Disconnect garden hoses from outdoor spigots and store them.
• Keep your home heated, including spaces that are easy to forget, like a finished basement or a room you don't use.
• Open cabinet doors under kitchen and bathroom sinks on exterior walls so warm air can reach the pipes.
• Know where your main water shutoff is and make sure everyone in the house knows too. If a pipe fails, closing the main limits the damage. Our guide on how to shut off your water in an emergency walks through it.
• Let a faucet drip slowly only if you have a vulnerable line and the temperature really does drop. Moving water is harder to freeze.

If you have a sprinkler system, don't improvise with it. Irrigation systems have exposed parts, and winterizing them properly is a job for a professional.

When to call a professional

The source covers Western Loudoun County, but a cold snap doesn't stop at a county line. If you're elsewhere in Northern Virginia, it's still smart to prepare, especially if you're in an older home or one with exposed plumbing.

Call a professional if you notice any of these after a cold night:

• Water pressure that drops sharply or a faucet that only trickles
• Water stains, bulging, or dampness on a wall, ceiling, or floor
• A spigot that drips or sprays after the temperature rises
• Any sound of running water when nothing is on

If you see water actively escaping, close the main shutoff first, then call. Please don't try to thaw or repair anything yourself. Heat applied the wrong way can cause more harm than the freeze did, and a cracked pipe needs a proper assessment. We serve homeowners across Loudoun County, and our emergency plumbing team is ready when a pipe fails at an inconvenient hour.
