Frozen or Burst Pipes: What To Do in This Cold Weather Emergency

Close up of leaking pipe

Save Time, Call Prime!

It can be quite a shock to turn on the water and have nothing come out. Or, even worse, to have water flooding your home from a burst pipe. But the reality is cold winter weather causes frozen or even burst pipes, which can quickly lead to costly damage if not addressed promptly.

Here’s what to do if you suspect a frozen or burst pipe.

First, Shut Off the Water Supply!

Whether your pipes are frozen or bursting, the first step is immediately shutting off the main water valve. Do you know where your main shut-off valve is? It’s usually located in the basement, garage, crawl space, or near the water heater or meter.

The water supply must be quickly turned off, so if you can’t find the main valve, call a plumber immediately.

If a pipe is frozen but has not burst, you may be able to shut off the water to only that pipe and continue using water in other areas of the home. Several valves control all or portions of the water supply throughout a residence. Some of the most common include:

 

Gate valves

Gate valveGate valves have a wedge-shaped gate or disc that can be lowered into or raised out of the water flow path to control water flow. Shut off the water supply by turning the circular handle (wheel) clockwise. It may take multiple full rotations to fully engage and turn the water off. Gate valves can seize up over time and become difficult to turn, especially for seniors. We recommend that you test gate valves, and if you find them hard to use, switch to a ball valve, as they are more reliable and easier for anyone to use.

Globe valves

Globe valveGlobe valves differ from gate valves in that they consist of a moveable plug and a stationary ring, typically in a spherical body (that’s where the name globe comes from!). Again, with this type of valve, you can shut off the water supply by turning the circular handle clockwise. Globe valves come with the same cautions as gate valves since they require multiple rotations, and grip strength can be prohibitive to some.

Ball valves

Ball ValveBall valves consist of a ball with a hole drilled through it and a long handle. The valve must be fully opened or closed to stop or allow water flow. When the handle is parallel to the water supply pipe, the valve is open, and when the handle is perpendicular to the pipe, the valve is closed. We believe this type of valve is the best option — if you have a gate or globe valve, we recommend converting to a ball valve.

You’ve Shut Off the Water; What Should You Do Next?

Now that the water is off, here are a few things you can do to identify and resolve the problem. It’s important to note that plumbers cannot fix a frozen pipe. The pipe must be thawed before any repairs can happen.

  • Identify the troublesome pipe: Look for bulges or cracks, dampness, or water stains on walls and ceilings. Areas most often associated with frozen pipes include unfinished basements, crawl spaces, garages, and attics.
  • Drain the system: Open all hot and cold water faucets, flush toilets, and turn off your boiler or water heater to relieve pressure in the pipes and prevent further damage. If there’s water leakage, turn off your electricity.
  • Thaw the frozen pipes carefully: Never use an open flame or torch to thaw pipes, as it can cause a fire, melt pipes, or cause the pipe to burst. Instead, thaw pipes with a hair dryer, heat lamp, electric heating pad on a low temperature, hot towels, or heat tape.
  • Temporarily patch the pipe: You may be able to temporarily patch the damaged pipes with pipe clamps, rubber sheeting, or epoxy putty to minimize water leakage. If your home has suffered extensive damage, contact your insurance company for guidance before making repairs. Document the damage with pictures.

When in Doubt, Call a Plumber

    Great work! Very nice service; fixed our water heater issue and had us back up and running in no time. The service provided by Ernie and Hayleigh was very professional and courteous.

    [UPDATE: RESOLVED] I'm updating this review to reflect that Prime Plumbing has owned up to the situation and made it right. Once my new toilet arrived, they returned and completed the installation at no additional cost to me. The 5-stars are for Ernie and Hailey who handled the final install, and they were a complete 180 from my previous experience. They were awesome, professional, and sociable. You could tell they actually enjoy their work and take pride in it. They got the job done right. While the road to get here was frustrating, I appreciate the company standing by their work and sending the right team to finish the job. [OLD REVIEW] I hired Prime Plumbing to fix a toilet leak, and after 4 visits and hundreds of dollars, I had to do their work for them. Here is the timeline of negligence: March 27, 2025 (Invoice #90891): I paid an $89 trip fee to have a technician come out. He did a visual glance without even lifting the toilet and told me "nothing was wrong." The leak continued. Nov 1, 2025 (Invoice #97073): I paid $634.56 for a "Toilet Pull and Reset" (Service Code TUR-110). The invoice states they would "prepare the mounting system." They claimed the issue was a decayed wax seal (after initially guessing "condensation"). They did not inspect the toilet for cracks, but they didn't miss the opportunity to try and upsell me a new water heater. The leak continued. Nov 24, 2025 (Return Call): When they came back, the technician tried to blame "condensation" again and claimed "these electric toilets aren't reliable", again making excuses. He replaced the wax seal again without inspecting the toilet. Nov 30, 2025: The leak returned. Before booking them again, I spent 1.5 hours doing what they should've done. I replicated the leak and reached behind the toilet to feel the failure point. I felt the wax ring and—crucially—I felt plastic obstructing the seal. Dec 1, 2025 (Invoice #97936 Return Call): The tech arrived, and I told him what I found. He told me, "That's impossible... Show me how you did it. Show me this magic." I had to literally get on the floor and prove it to him. I ABSOLUTELY should not have had to do his job for him. He then complained about how he "can't keep coming out here" and is "losing money." Completely unprofessional. He finally pulls the toilet up, actually inspects it, and finds a crack. He sounded gleeful showing it to me, acting like this vindicated his misdiagnosis. He then told me I need to pay a third time to have a new toilet installed. THE REALITY: Did he inspect it the first time? If he did and saw no crack, then he caused the crack by mishandling the toilet. Did he not inspect it? Then the crack was there the whole time, and due to his incompetence, he misdiagnosed the issue for months while taking my money. I paid premium pricing for a professional diagnosis and fix. Instead, I got laziness in March, incompetence in November, disrespect in December, and an issue that wasn't fixed. Now they want more money to fix the issue they likely caused. Avoid this company unless you want to do the plumbing yourself after paying the bill. When my new toilet arrives, I will be reaching out to them to complete the install of the toilet at no additional cost to myself (I am not asking for a refund on the cost of a toilet, just want them to install it properly.) Otherwise, this is definitely going to be a complaint to the MHIC.

    Ernie and Hailey are absolute legends! I cannot say enough good things about Ernie and Hailey! I hired them to install a new toilet, and they turned what is usually a mundane maintenance appointment into a genuinely great experience. From the moment they arrived, the service was top-tier. They were incredibly professional and got the installation done flawlessly, but what really stood out was their attitude. They were sociable, friendly, and you could tell they actually have fun on the job. They have a great dynamic and brought such positive energy into my home while working. It is rare to find a team that combines expert workmanship with such a great "vibe." If you need plumbing work done and want it done right by good people, ask for Ernie and Hailey. 10/10 would recommend!
