What Should You Do If a Pipe Freezes in Your Home?

November 12, 2025

When temperatures drop below freezing, one of the most common and costly plumbing problems homeowners face is a frozen pipe. Not only can frozen pipes block water flow, but they also pose a serious risk of bursting, leading to flooding and expensive repairs.


At Pleasant Valley Plumber, we’ve helped many homeowners handle and prevent cold-weather plumbing emergencies. Here’s what you should do if a pipe freezes in your home—and how to stop it from happening again.

1. Turn Off the Water Supply Immediately

The first and most important step is to shut off your home’s main water supply. This helps relieve pressure in the pipes and minimizes the chance of a rupture.

Once the water is off, open nearby faucets to allow any built-up steam or water to escape as the pipe begins to thaw.


If you’re unsure where your main shut-off valve is located, it’s typically found near the water meter or along an exterior wall where the main line enters the home.


2. Locate the Frozen Section

Look for areas of your plumbing system that feel unusually cold, frosty, or bulging. Common places for frozen pipes include:

  • Unheated basements or crawl spaces
  • Garages or exterior walls
  • Under sinks located against outside walls

Once you identify the frozen area, determine whether the pipe is accessible or hidden behind drywall or insulation.


3. Begin Thawing Safely

If the pipe is visible and accessible, you can begin gently thawing it. Always start the process closest to the faucet and work your way back toward the frozen section. Safe methods include:

  • Using a hair dryer to apply warm air evenly.
  • Placing warm towels or heating pads along the pipe.
  • Setting up a space heater nearby to warm the room gradually.

Avoid using open flames or propane torches, as these can damage pipes or cause fires.

If the pipe is hidden behind walls, it’s safer to call a professional plumber who can thaw it safely without damaging your plumbing or drywall.


4. Check for Leaks Once Thawed

After the water begins flowing again, inspect the pipe closely for cracks or leaks. Even a small split can lead to significant water damage once full pressure returns.


If you discover any damage, keep the water turned off and contact Pleasant Valley Plumber right away for emergency repair service.


5. Prevent Future Freezing

Once the immediate problem is solved, take steps to prevent future frozen pipes:

  • Insulate exposed pipes in basements, garages, and crawl spaces.
  • Keep cabinet doors open under sinks to allow warm air circulation.
  • Maintain indoor temperatures at 55°F or higher—even when away.
  • Let faucets drip slightly during extreme cold to keep water moving.

Preventive maintenance is the most effective way to avoid repeated winter plumbing issues.


6. When to Call a Professional

If you can’t locate the frozen pipe, the pipe has burst, or you’re unsure how to thaw it safely, it’s time to call a licensed plumber. A professional has the right tools and expertise to fix the issue quickly and prevent further damage.


At Pleasant Valley Plumber, our team offers fast, reliable frozen pipe repair and winter plumbing maintenance services to protect your home all season long.

How Do I Improve Water Temperature Consistency in Winter?

October 20, 2025
Why Water Temperature Fluctuates in Winter When the cold weather hits, many homeowners notice sudden changes in water temperature —especially when running showers or using multiple fixtures at once. The problem often lies in your plumbing system’s water heater performance and overall demand during colder months. At Pleasant Valley Plumber , we help homeowners across Northeast Pennsylvania keep their water heaters , pipes, and plumbing systems running efficiently all year long. Common Causes of Temperature Inconsistency 1. Cold Incoming Water Supply In winter, the water entering your home’s pipes is significantly colder. This makes your water heater work harder to reach the desired temperature, which can lead to fluctuating hot water or lukewarm output. 2. Sediment Buildup in Your Water Heater Over time, mineral deposits and sediment collect in the tank, especially in homes with hard water. This buildup acts as insulation, making it harder for the heating elements to warm the water properly. Scheduling regular water heater maintenance or flushing the tank can restore heating efficiency and improve temperature consistency . 3. Water Heater Size or Capacity Issues If your water heater is undersized , it may not keep up with household demand in winter. For example, running the dishwasher and shower simultaneously can quickly deplete the tank. Upgrading to a larger tank or a tankless water heater ensures a continuous supply of hot water, no matter how cold it gets outside. 4. Faulty Mixing Valves or Thermostats If you experience sudden bursts of hot or cold water, your mixing valve or thermostat may be malfunctioning. These components regulate temperature by blending hot and cold water. A simple replacement or calibration can solve this issue quickly.
