You Will Need

  • A pipe insulator
  • Caulk

Steps

  1. Step 1

    Attend to outdoor hoses

    Unhook, drain, and store outdoor hoses. Close any inside water valves that supply outdoor hose bibs. Leave outdoor hose bib valves open to allow water to drain out.

  2. Remember to drain water from swimming pool and sprinkler supply lines.

  3. Step 2

    Insulate pipes

    Find exposed pipes in unheated areas, such as basements, attics, and garages, and install insulation, such as a pipe sleeve, heat cable, or heat tape, on both cold and hot water pipes.

  4. Use insulation products approved by an independent testing organization.

  5. Step 3

    Seal air leaks

    Use caulk to seal any areas where cold air can come in from. Look for air leaks around electrical wiring, dryer vents, and pipes.

  6. Step 4

    Keep the garage closed

    Keep the garage door closed whenever possible to keep pipes in that space from freezing.

  7. Step 5

    Open cabinets

    Open kitchen and bathroom cabinets on exterior walls to allow warm air to circulate around pipes.

  8. Step 6

    Run water

    Let warm water drip from an exterior-wall faucet overnight when below-freezing temperatures persist.

  9. Step 7

    Keep the house warm

    Keep the thermostat above 55 degrees – don't get caught off guard by a flooding basement!

  10. Even a small crack in a pipe can leak up to 250 gallons of water in a day.
