How to Prevent Frozen Pipes in Your Baltimore Home This Winter

Fluid Plumbing & Heating has helped homeowners across Baltimore, Towson, Perry Hall, Parkville, and surrounding communities since 2017. Many homes in the area were built decades ago, with plumbing that runs along exterior walls, through unheated crawl spaces, and into garages that were never insulated. Those are exactly the places where pipes freeze first.

The good news is that most frozen pipes are preventable. A little preparation before the first hard freeze, plus a few habits during cold snaps, can protect your plumbing and save you from an expensive repair.

Not every pipe in your home carries the same risk. Pay the most attention to lines that are exposed to cold air or sit close to the outside of the house.

The most vulnerable areas include:

• Pipes in unheated basements, crawl spaces, and garages
• Supply lines running along exterior walls
• Plumbing under kitchen and bathroom sinks on outside walls
• Outdoor hose bibs and spigots
• Pipes in attics or near poorly sealed windows and doors
• Lines serving additions or rooms that were built later and insulated differently

If you are not sure where your pipes run, the cold spots in your home are a good place to start looking.

The best time to protect your pipes is in the fall, before overnight temperatures drop into the twenties.

Start by disconnecting garden hoses from outdoor spigots. A hose left attached traps water in the faucet and the line behind it. If your home has an interior shutoff valve for outdoor faucets, close it and open the outdoor faucet to let the line drain.

Next, insulate exposed pipes in unheated spaces. Foam pipe sleeves are inexpensive and easy to install on accessible lines in basements, crawl spaces, and garages. For pipes that run close to cold exterior walls, sealing gaps where cold air gets in can make a real difference.

Finally, know where your main water shutoff valve is and make sure it turns. If a pipe does burst, shutting off the water quickly is the single most important step you can take to limit damage.

Your heating system is your plumbing's first line of defense. A furnace or boiler that quits during a cold snap leaves every pipe in the house exposed to falling temperatures.

Scheduling a heating checkup before winter helps catch worn parts, ignition problems, and circulation issues before they leave you without heat. If your system is older or has needed several repairs, it may be worth talking with a technician about heating repair or heating installation options before the coldest weeks arrive.

Homes heated by hot water also benefit from having their boilers inspected, since a boiler that stops circulating can put both the heating system and the plumbing at risk.

When the forecast calls for single digits or several days below freezing, a few simple habits help keep water moving and pipes warm:

• Let a faucet on an exterior wall drip slightly overnight
• Open cabinet doors under sinks so warm air can reach the pipes
• Keep the thermostat at a steady temperature day and night
• Keep the garage door closed if plumbing runs through the garage
• Set the heat no lower than the mid-fifties if you will be away from home

Moving water is much harder to freeze, and a steady indoor temperature keeps the spaces around your pipes from getting too cold.

A frozen pipe usually announces itself when you turn on a faucet. Watch for:

• A faucet that produces only a trickle or no water at all
• Frost on the outside of an exposed pipe
• Unusual odors from a drain
• A section of pipe that is bulging or visibly cracked

If only one fixture is affected, the frozen section is likely somewhere along the line that serves it.

If you suspect a frozen pipe, leave the faucet open so water can flow once the ice begins to melt. Warm the area gradually with a hair dryer, a space heater kept a safe distance away, or warm towels wrapped around the pipe.

Never use an open flame, a propane torch, or a heat gun on a frozen pipe. Uneven, extreme heat can damage the pipe and create a serious fire hazard.

If you cannot reach the frozen section, cannot restore flow, or see any sign of cracking or leaking, shut off the main water valve and call a licensed plumber. A pipe that has split will start leaking the moment it thaws.

A burst pipe can release a large amount of water in a short time. Turn off the main water supply right away, shut off power to any area where water is near outlets or appliances, and move belongings out of the way.

At what temperature do pipes freeze?

Pipes in unheated or poorly insulated areas are at risk when outdoor temperatures fall into the low twenties or below, especially over several hours or several days. Lines exposed to wind or cold drafts can freeze sooner than pipes in protected spaces.

Should I let my faucets drip in cold weather?

Letting a faucet on an exterior wall drip slightly during very cold nights can help keep water moving through the line. It is a simple step that reduces the chance of a freeze in the most exposed pipes.

Can I thaw a frozen pipe myself?

If the frozen section is easy to reach and the pipe is not damaged, you can warm it gradually with a hair dryer or warm towels while the faucet is open. Never use an open flame. If you cannot find the frozen section or see any cracking, call a plumber.

How do I know if a frozen pipe has burst?

Water stains, dripping, damp drywall, or the sound of running water after a pipe thaws are common signs. If you suspect a burst pipe, shut off the main water valve and call for emergency plumbing service.
