How to Prevent Frozen Pipes During Cold Winter Months

Frozen pipes can burst and cause expensive water damage, especially when it stays below 20°F for a long time. To prevent this, insulate your pipes, keep your home warm, and let faucets drip to keep water flowing. If your pipes freeze, use a heating pad or hair dryer to thaw them safely and avoid damage.

Frozen pipes aren’t just a hassle—they can cause serious damage.

When it gets cold, water inside your pipes can freeze, expand, and block water flow.

This builds pressure between the ice and the faucet, which can cause the pipe to burst and flood your home.

A burst pipe can spill hundreds of gallons of water, soaking walls, floors, and insulation.

If not caught in time, this can lead to mold, structural damage, and costly repairs.

Even if the pipes don’t burst, freezing can weaken them and cause leaks later.

Although winters in Dallas, TX aren’t as severe as those in the Northeast, sudden cold snaps can still put home plumbing at risk.

Outdoor hose bibs, crawl spaces, attics, and unheated basements are most at risk.

Even indoor pipes along exterior walls can freeze if they’re not well insulated.

Preventing frozen pipes is easier and cheaper than fixing the damage.

Simple steps—like wrapping pipes, sealing drafts, and keeping indoor temperatures steady—can save homeowners from expensive repairs and emergency plumbing calls.

Knowing the risks now can help protect your plumbing when the temperature drops.

How Frozen Pipes Occur

Water expands when it freezes, and this puts pressure on plumbing.

If the pressure gets too high, pipes can burst.

Pipes are most at risk when temperatures drop to 20°F (-6.7°C) or lower for six hours or more.

Uninsulated or exposed pipes in basements, crawl spaces, attics, garages, and exterior walls are the most vulnerable.

Frozen pipes occur when the surrounding cold air makes the water inside turn to ice.

The risk goes up if there’s poor insulation or cold air sneaks in through cracks or gaps.

As ice forms inside the pipe, it blocks water flow.

This forces water to push against the closed tap.

Too much pressure can cause the pipe to crack or burst, leading to big leaks and even flooding.

Pipes don’t always burst where the ice forms.

The worst damage often happens between the frozen section and the closed faucet, where pressure builds the most.

This pressure is a major reason pipes fail in freezing weather.

Knowing why and where frozen pipes occur helps homeowners prevent costly damage.

Adding insulation, sealing drafts, and keeping indoor heat on can help protect your plumbing before temperatures drop.

When the temperature drops in Dallas, TX, you need to spot the signs of frozen pipes before they cause costly damage.

One big warning is low water pressure.

If your faucet slows to a trickle, ice may be forming inside your plumbing.

Another sign is strange noises like banging, whistling, or gurgling when you turn on the tap.

This could mean water is trying to push past an ice blockage.

Also, if you see frost on exposed pipes, especially in basements, attics, or garages, the pipe temperature is dangerously low.

A less obvious warning is weird smells from drains or faucets.

If a pipe freezes, trapped air and gases may cause foul odors to back up into your home.

If you notice any of these signs, act fast.

Open cabinet doors, turn up the heat, and, if needed, call Benjamin Franklin Plumbing of Dallas, TX before a freezing issue turns into a burst pipe nightmare.

Waiting too long can lead to expensive water damage and major plumbing repairs.

Best Ways to Prevent Frozen Pipes at Home

Stopping frozen pipes takes a few simple steps and can save you from expensive repairs and water damage.

One of the best ways is to insulate exposed pipes, especially in cold spots like attics, basements, and crawl spaces.

Using foam or fiberglass sleeves helps keep water warm and lowers the risk of freezing.

Keeping a steady indoor temperature also helps.

Never let your home drop below 55°F, even if you’re not home.

A constant temperature keeps water moving so it won’t freeze.

A small but useful trick is opening cabinet doors under sinks, especially in kitchens and bathrooms.

This lets warm air reach the pipes and lowers the risk of freezing.

Also, sealing cracks or gaps near pipes helps keep out cold air.

For homes in North Texas, where sudden cold snaps can surprise homeowners, getting a plumbing inspection can help find weak spots.

If you’re worried about your pipes, pipe repair services can strengthen your system before freezing weather hits.

A little prep now can save you from the hassle of burst pipes in the middle of winter.

Why You Should Let Faucets Drip in Cold Weather

Letting faucets drip in freezing weather isn’t just an old myth—it really helps stop frozen pipes from forming.

Moving water is much less likely to freeze.

Even a slow trickle keeps water flowing and eases pressure buildup, which is what causes pipes to burst.

How Running Water Stops Freezing

When it gets really cold, still water in plumbing can freeze.

Ice blocks water flow, and pressure builds up between the frozen spot and the nearest closed faucet.

This pressure can cause the pipe to burst.

Keeping water moving lowers the risk of ice forming.

Which Faucets to Let Drip and When

You don’t need to drip every faucet.

Focus on those connected to exposed or poorly insulated pipes, like ones in basements, crawl spaces, and exterior walls.

If temps drop below 20°F for a long time, turn on both hot and cold taps to keep water moving through the system.

Even a small trickle of water helps prevent freezing by keeping pipes active.

When paired with pipe insulation, this simple step is one of the cheapest ways to avoid costly winter plumbing problems in places like Dallas, TX.

Protecting Outdoor Pipes and Hose Bibs

Outdoor pipes can freeze fast in cold weather, so prepping them is key.

If you don’t protect them, you risk cracked pipes, leaks, and expensive water damage from frozen pipes.

Disconnect and Store Garden Hoses

One easy way to stop outdoor plumbing from freezing is to disconnect, drain, and store garden hoses before it gets too cold.

Leaving a hose attached traps water in the spigot.

When it freezes and expands, it can crack the pipe inside the wall, leading to frozen pipes that may require costly repairs.

Use Faucet Covers for Outdoor Spigots

Putting insulated faucet covers on hose bibs adds a layer of protection.

These covers hold in heat and keep freezing air out.

If you don’t have a cover, wrap the spigot in thick fabric and secure it with plastic as a quick fix.

Keep Garage Doors Closed

If your water lines run through the garage, keep the garage door shut to help keep the space warmer.

Cold air sneaking in can expose pipes to freezing temps, making them more likely to burst.

How to Safely Thaw Frozen Pipes

Thawing frozen pipes slowly is key to avoiding bursts.

Follow these steps to get water flowing again safely:

1. Find the affected area – Look for frost, bulging, or ice on exposed plumbing. If unsure, turn on faucets. If little to no water comes out, a pipe leading to that faucet is likely blocked by ice.
2. Open the faucet – Keep the tap open. This helps release pressure and lets melting ice drain out.
3. Apply steady heat – Use a hairdryer, heating pad, or space heater (kept away from flammable items) to warm the pipe. Never use an open flame like a torch or propane heater, as it can damage pipes or start a fire.
4. Work from the faucet back – Start heating near the open faucet and move toward the frozen section. This prevents steam buildup, which can cause a burst.
5. Watch closely – As ice melts, water flow will improve. Keep applying heat until full pressure returns.

If you can’t find the frozen area or a pipe has already burst, call Benjamin Franklin Plumbing of Dallas, TX right away.

Waiting too long can lead to major water damage and costly repairs.

A burst pipe can cause major damage fast, so you need to act quickly.

First, turn off the main water supply right away to stop the flooding.

If you don’t know where it is, find out now—it’s usually near the water meter.

Next, turn off electricity in the affected area to avoid electrical hazards.

Once the water is off, drain the pipes by turning on all faucets to release pressure.

Use towels, buckets, or a wet/dry vacuum to soak up standing water and reduce damage to floors and walls.

If water seeps into carpets or drywall, mold can grow fast.

Find the burst pipe if it’s visible.

A small crack may trickle, while a big break will gush.

Avoid DIY fixes—temporary patches don’t last.

Call a professional emergency plumber to handle the repair.

The team at Benjamin Franklin Plumbing of Dallas, TX has the tools and skills to fix frozen pipes before they cause bigger problems.

While waiting, open doors or use fans to help dry things out.

If it’s freezing outside, keep the heat on to prevent additional plumbing issues.

Acting fast can save you thousands in repairs, so don’t wait—call a plumber ASAP.

Why Professional Plumbing Inspections Matter

Stopping frozen pipes from occurring isn’t just about acting when it gets cold—it’s about keeping up with maintenance all year.

A plumbing inspection helps make sure your home is ready for freezing temps and avoids costly damage.

Plumbers can spot trouble areas like uninsulated pipes, hidden leaks, or places where cold air sneaks in before they turn into big problems.

One common but often missed issue is drafts near electrical wiring, dryer vents, or plumbing access points.

These small gaps let in cold air that can lead to pipe freeze-ups.

A good plumber will seal these spots to keep your pipes safe from the cold, reducing the risk of frozen pipes forming in vulnerable areas.

Seasonal checkups also include looking for leaks or weak joints, which are more likely to freeze and burst under pressure.

Finding these issues early can save you from unexpected trouble in the middle of winter.

If you think you might have hidden leaks, getting a leak check now can prevent costly damage before it’s too late.

Beyond preventing frozen pipes, plumbing inspections save money by making your system run better.

A well-kept system cuts down on wasted water, inefficiencies, and emergency repairs.

If you’re in Dallas, TX, think about booking a plumbing inspection with Benjamin Franklin Plumbing of Dallas, TX to make sure your home is ready for winter.

Winterizing Your Home Plumbing System

Getting your plumbing ready for winter isn’t just a good idea—it’s a must to avoid frozen pipes and costly repairs.

A few simple steps can keep your water running even in freezing weather.

Preventing frozen pipes now can save you from expensive damage later.

Insulate and Seal

Cover exposed plumbing in unheated areas like basements, attics, and crawl spaces.

Use foam sleeves, fiberglass insulation, or heat tape to help keep water warm.

Seal gaps around plumbing, electrical wires, and vents to stop cold air from creeping in, which can lead to frozen pipes.

Use Heat Tape or Heat Cables

If your lines freeze easily, heat tape or heat cables can help.

These wrap around pipes and provide steady warmth, even in extreme cold.

When installed right, they lower the risk of freezing and bursting.

Keep Your Home Warm

Set your thermostat to at least 55°F, even if you’re away, to stop water lines from freezing.

If you travel, ask a neighbor to check on your home, or shut off and drain your water supply to prevent buildup in pipes.

Common Myths About Frozen Pipes Debunked

Believing the wrong info about frozen pipes can cost you.

Let’s clear up some common myths.

Myth 1: Only Outdoor Pipes Freeze

Many think water lines freezing is only an issue outside.

But any pipe exposed to cold air—inside or outside—can freeze.

This includes pipes in basements, crawl spaces, and even cabinets near outside walls.

Myth 2: Hot Water Pipes Won’t Freeze

It sounds reasonable to think hot water pipes won’t freeze, but that’s not true.

If it gets cold enough, even hot water pipes can freeze, especially if they lack insulation.

Myth 3: Dripping Faucets Waste Water Without Helping

Some worry that letting faucets drip just increases the water bill.

But even a small trickle keeps water moving and lowers the chance of freezing.

This small step can save you from costly repairs.

Myth 4: Keeping Your Home Warm is Enough

Heating your home helps, but cold spots in cabinets, attics, or garages can still freeze pipes.

A good trick is to open cabinet doors and attic hatches so warm air can reach problem areas.

Myth 5: Using an Open Flame is the Best Way to Thaw Pipes

This isn’t just wrong—it’s dangerous.

Safer options include an electric heating pad, hair dryer, or space heater (kept away from anything flammable).

Never use a blowtorch or open flame, as this could damage pipes or start a fire.

If you’re in Dallas, TX, consider reaching out to a local professional for safe and effective solutions.
