How to Prevent Frozen Pipes: Getting Ready for Colder Weather

frozen pipes

Winter’s chill isn’t just uncomfortable—it can be costly. When water freezes in your home’s plumbing, it expands and creates extreme pressure inside the pipe. That pressure can crack or burst even sturdy lines and lead to serious water damage. The good news: with a little preparation, most frozen-pipe emergencies are preventable.

Why Pipes Freeze

  • Expanding ice: Water expands as it turns to ice, increasing pressure inside pipes.
  • Cold zones: Pipes in unheated or poorly insulated spaces—crawlspaces, basements, attics, garages, and exterior walls—are most vulnerable.
  • Low flow: Standing or slow-moving water freezes faster than water that’s moving.

Preventive Steps to Take Before the First Freeze

Start early. A quick weekend of prep can save you from expensive repairs later.

Area What to Do
Outdoor Spigots & Hoses
  • Disconnect and drain garden hoses; store them indoors.
  • Install faucet covers or insulate hose bibs.
  • Shut off and drain exterior water lines if they have a dedicated shutoff.
Sprinklers & Seasonal Lines
  • Winterize irrigation systems per manufacturer recommendations.
  • Blow out sprinkler lines if required.
Exposed Indoor Pipes
  • Insulate exposed pipes with foam sleeves or fiberglass wrap.
  • Use UL-listed heat cable/heat tape where appropriate (follow instructions carefully).
  • Seal gaps and cracks near pipes to block cold drafts.
Crawlspaces, Basements & Garages
  • Keep garage doors closed during cold snaps, especially if plumbing runs through the garage.
  • Add insulation to rim joists, walls, and access doors.
  • Consider insulating or enclosing crawlspace vents during extended freezes (as local codes allow).
Interior Sinks on Exterior Walls
  • Open cabinet doors to allow warm air to circulate around supply lines.
  • Relocate supply lines away from exterior walls during remodels if possible.
Whole-Home Settings
  • Maintain a steady thermostat setting; avoid letting the home drop below 55°F when away.
  • During extreme cold, let vulnerable faucets drip slightly to keep water moving.
  • Ensure attic insulation is adequate to keep ceilings (and the pipes above them) warmer.
Vacant & Seasonal Homes
  • Consider full winterization: shut off the main water supply and drain the system.
  • Ask a trusted person to check the property during cold spells or use smart leak/temperature monitors.

What to Do If a Pipe Freezes

  1. Shut off the water supply at the main valve to reduce flooding risk if the pipe bursts.
  2. Thaw the pipe safely: Use a hair dryer, heat lamp, or electric heating pad. Start closest to the faucet and move toward the frozen area. Never use an open flame.
  3. Open the faucet to relieve pressure and allow melting ice to drain.
  4. Inspect for leaks as lines thaw; even small cracks can cause significant damage.
  5. Call a professional if you can’t locate the freeze, suspect a burst, or need expert repairs.

Pro Tips to Stay Ahead of Winter Weather

  • Install smart leak detectors and automatic shutoff valves for peace of mind.
  • Label the main water shutoff and ensure everyone in the household knows where it is.
  • Schedule a pre-winter plumbing check to identify hidden vulnerabilities.

Quick Checklist Before the Deep Freeze

  • Disconnect & drain hoses; cover outdoor faucets.
  • Insulate exposed pipes (add heat cable where needed).
  • Seal drafts around pipe penetrations.
  • Keep garage doors closed during cold snaps.
  • Open sink cabinets on exterior walls; let vulnerable taps drip.
  • Hold indoor temps steady (55°F or higher when away).
  • Winterize vacant or seasonal properties.
  • Know your main shutoff location and keep tools handy.
