what to do if you have frozen pipes
If you think your pipes are frozen, act quickly but carefully to avoid a burst and water damage. Here’s a clear, SEO‑friendly guide on what to do if you have frozen pipes at home this winter.
What to Do If You Have Frozen Pipes
Quick Scoop
- Turn off the main water supply to limit damage if a pipe bursts.
- Open nearby faucets to relieve pressure and help thawing.
- Gently warm the pipe with safe heat sources (hair dryer, heating pad, space heater), never with an open flame.
- If you see cracks, leaks, or can’t find the frozen section, call a plumber immediately.
- Soak up any escaped water and protect belongings if a pipe has already burst.
Step‑by‑Step: First Things to Do
- Confirm it’s likely frozen pipes
- No or very low water from one or more faucets during a cold snap is a classic sign.
* Check multiple taps to see which parts of the house are affected.
- Shut off the main water (if you suspect a burst)
- If you hear hissing, see bulging pipes, or notice water stains, turn off your main shut‑off valve right away.
* This limits how much water can escape when the ice plug melts.
- Open faucets
- Open both hot and cold taps connected to the frozen line.
* This relieves pressure and gives melting water somewhere to go instead of building up in the pipe.
- Locate the frozen section if you can
- Look in unheated or poorly insulated areas: basements, crawlspaces, attics, garages, exterior walls, or near outdoor spigots.
* Signs include visible frost on the pipe or sections that feel much colder than others.
How to Safely Thaw Frozen Pipes
Once you have an idea where the pipe is frozen and you don’t see active leaking, you can attempt gentle, controlled thawing.
Safe ways to apply heat
- Hair dryer
- Move the warm air back and forth along the frozen section, starting closer to the faucet and working back toward the coldest area.
- Electric heating pad or heat tape (approved for pipes)
- Wrap it around the affected area and follow manufacturer instructions.
- Portable space heater in the room
- Place it a safe distance away, not directly touching the pipe, and keep it supervised.
- Warm towels
- Soak towels in hot (not boiling) water, wring them out, and wrap them around the pipe, replacing them as they cool.
While you are doing this, keep nearby faucets open so you can see when water starts flowing again.
What you must NOT do
- Do not use an open flame: no blowtorch, propane torch, charcoal grill, or gas stove.
- Do not leave electric heaters, heat guns, or hair dryers unattended.
- Do not overheat plastic pipes, which can soften or melt under high heat.
If a Pipe Has Already Burst
Once a pipe bursts, your priority shifts from thawing to damage control.
- Shut off the main water completely
- Turn the main valve to the off position; if you live in a multi‑unit building, contact building management immediately.
- Turn on all taps and flush toilets
- Let remaining water drain out so less remains in the system to leak.
- Soak up and contain water
- Use towels, mops, and buckets to collect standing water and move furniture, electronics, and valuables out of the affected area.
* Document damage with photos or videos for insurance.
- Call a licensed plumber
- A professional can locate hidden damage, replace sections of pipe, and use specialized thawing equipment if there are still frozen sections.
- Contact your insurer if damage is significant
- Many home policies cover sudden water damage from burst pipes, and they may recommend approved contractors or restoration services.
What to Do While You Wait for a Plumber
- Keep the heat on
- Maintain indoor temperature close to or above normal room temperature to encourage gradual thawing.
- Open cabinets and interior doors
- Open kitchen and bathroom sink cabinets and doors so warm air can circulate around hidden pipes.
- Use buckets and towels as a “guard”
- If a section looks stressed or is starting to drip, place buckets or pans underneath and pad the area with towels.
- Avoid DIY wall demolition
- Cutting into walls or ceilings to chase a frozen line is usually more expensive to fix than having a pro use proper equipment.
A real‑world example: many property managers now keep emergency relationships with plumbers who have electric thawing machines, which can clear a frozen metal pipe in under 10 minutes in some cases.
How to Prevent Frozen Pipes Next Time
Even though your question is about what to do now , prevention is a big part of the frozen‑pipe conversation every winter, especially in recent cold snaps that have hit areas not used to deep freezes.
Everyday cold‑weather habits
- Let vulnerable taps drip slightly during extreme cold to keep water moving.
- Keep the thermostat set to a consistent temperature day and night, even if you’re away.
- Open under‑sink cabinet doors in kitchens and bathrooms on exterior walls.
Home improvements that help
- Add or upgrade insulation around pipes in basements, crawlspaces, attics, and exterior wall runs.
- Seal air leaks around windows, doors, sill plates, and pipe penetrations where cold air can blow directly on pipes.
- Install heat cable/heat tape on particularly exposed lines (such as outdoor spigots or pipes along exterior walls), using products rated for that purpose.
- For outdoor faucets, use frost‑free hose bibs and disconnect hoses before winter.
Mini “Forum Discussion” View
“My bathroom sink pipes froze in Chicago, they thawed and now my hot line drips and the cold line has water hammer. Any ideas?” – A typical winter plumbing thread.
Common community advice from forums and plumber megathreads in recent winters tends to align with professional guidance:
- People who knew where their main shut‑off was and used it early often reported far less damage after a thaw.
- Many who only ran hot water and ignored cold lines still experienced freezes, especially on long runs or exterior walls.
- A recurring theme: “Don’t wait days for it to thaw on its own if you see bulging or hear strange sounds—shut off water and get a pro.”
