Posted on | by Arrow Plumbing
Frozen pipe with frost and condensation, illustrating plumbing issues related to cold weather in Houston, emphasizing the need for prevention and thawing methods.

Houston homes are not designed to endure the hard freezes we experience once or twice a year. When temperatures drop, frozen pipes become a significant issue for many homeowners, often leading to bursts and severe water damage. If you suspect your pipes are frozen or have already burst, follow this guide to protect your home and restore your plumbing.

What to Do If Your Pipes Are Frozen

1. Turn Off Your Water Supply »

  • If a pipe has burst, shut off the water at the city meter immediately.
  • Use a water key or call the city or your water provider for assistance.
  • If waiting for help, try shutting off the water where it enters your home.

2. Watch for Leaks as Temperatures Warm

  • When the pipes start to thaw, carefully inspect for leaks.
  • If you spot any damage, contact Arrow Plumbing for emergency repairs at 281.240.6868.

How to Thaw Frozen Pipes

If your pipes are frozen but haven’t burst, act quickly to restore water flow and prevent further damage.

Important Safety Note:

Never use a torch or any open flame to thaw pipes. This creates a severe fire hazard and could cause structural damage.

Signs of a Frozen Pipe:

  • No water or only a trickle when turning on the faucet.
  • Frost or condensation on exposed pipes.

Thawing Frozen Pipes: Step-by-Step For Exposed Pipes

If the frozen pipe is visible (e.g., in an attic, under a sink, or outdoors), use one of these safe thawing techniques:

1. Hair Dryer

  • Use a high-power hair dryer to warm the frozen section.
  • Open the faucet and heat the pipe from the faucet back toward the frozen area to allow water to flow out as the ice melts.

2. Heat Lamp

  • Position an infrared or incandescent heat lamp to warm the pipe.
  • Keep flammable materials (e.g., drapes or paper) away from the heat source to avoid fire hazards.

3. Small Portable Heater

  • Place a fan heater near the frozen section, directing heat onto the pipe.
  • Keep safety in mind by avoiding contact with flammable materials under cabinets.

For Pipes Behind Walls or Ceilings

Thawing pipes in inaccessible areas is more challenging. Try these approaches:

  • Increase Room Temperature: Use space heaters or raise the thermostat to warm the area.
  • Access the Pipe: If practical, remove part of the wall or ceiling to directly heat the pipe using one of the methods above.

Preventing Frozen Pipes in Houston »

To avoid frozen pipes during future freezes:

    1. Insulate Exposed Pipes: Wrap pipes in attics, crawl spaces, and outdoors with foam
      insulation.
    2. Keep Cabinet Doors Open: Allow warm air to circulate around pipes under sinks.
    3. Maintain Consistent Heating: Keep your thermostat at 60°F or higher, even if you’re
      away.
