The short answer: Winterizing your outdoor faucets takes about 15 minutes and costs nothing if you do it yourself. You need to shut off the interior valve that feeds each outdoor faucet, open the outdoor spigot to drain remaining water, and disconnect any attached hoses. Skip this step and a single burst pipe can cost $1,000 to $4,000 to repair, not counting water damage to walls, floors, and belongings. The American Red Cross and most plumbing professionals recommend winterizing outdoor faucets before the first hard freeze, which means late October in northern states and late November to December in the South.
Frozen pipes are one of the most common and most preventable home disasters in the United States. According to the Insurance Information Institute, frozen and burst pipes are one of the top causes of homeowner property damage claims during winter months. The good news is that protecting your outdoor faucets requires no special tools, no professional help, and very little time.
Why Outdoor Faucets Freeze First
Outdoor faucets (also called hose bibs or spigots) are the most vulnerable point in your home’s plumbing during winter. They are exposed to outdoor temperatures with minimal insulation. When water inside the pipe behind the faucet freezes, it expands with tremendous force, roughly 2,000 pounds per square inch. That is enough to split a copper pipe or crack a brass fitting.
The pipe does not burst where the ice forms. It bursts between the ice blockage and the closed faucet, where pressure builds up with nowhere to go. This means the actual burst often happens inside your wall, where you will not see it until the ice thaws and water starts flowing through the crack.
This is exactly the kind of surprise that first-year homeowners need to know about before their first winter in a new house.
Step-by-Step: How to Winterize Your Outdoor Faucets
Step 1: Locate Your Interior Shutoff Valves
Every outdoor faucet should have a dedicated shutoff valve inside your home. These are typically found in the basement, crawl space, or utility room, along the wall where the outdoor faucet exits the house.
Look for a small valve (usually a gate valve with a round handle or a ball valve with a lever handle) on the pipe that leads to each outdoor faucet. In some homes, especially those built before 1970, there may not be individual shutoff valves for outdoor faucets. If that is the case, you have two options:
- Have a plumber install shutoff valves ($150 to $300 per valve). This is a one-time investment that makes winterizing simple for years to come.
- Use your home’s main water shutoff as a last resort, though this shuts off water to the entire house.
Step 2: Turn Off the Interior Valve
Close each interior shutoff valve that feeds an outdoor faucet. For a gate valve, turn the handle clockwise until it stops. For a ball valve, turn the lever 90 degrees so it is perpendicular to the pipe.
Step 3: Open the Outdoor Faucet
Go outside and open each faucet fully. This allows any water remaining in the pipe between the shutoff valve and the faucet to drain out. Leave the faucet in the open position all winter. This is important because it allows any residual water to expand without building pressure if temperatures drop below freezing.
Step 4: Open the Bleeder Cap (If You Have One)
Some interior shutoff valves have a small bleeder cap or petcock on the downstream side. If yours does, place a bucket underneath and open it to let any trapped water drain completely. Close the bleeder cap once the water stops dripping.
Step 5: Disconnect and Drain All Hoses
This step is critical and is the one most people forget. A hose left connected to an outdoor faucet traps water in the faucet body and the pipe behind it, making freezing almost guaranteed even with frost-free faucets.
Remove all garden hoses, splitters, timers, and spray nozzles from outdoor faucets. Drain the hoses by stretching them out on a slope and letting gravity do the work. Coil them and store them in a garage or shed.
Step 6: Install Faucet Covers (Optional but Recommended)
Insulated faucet covers cost $3 to $8 each at any hardware store. They provide an extra layer of freeze protection and are especially worthwhile if:
- You live in a region where temperatures regularly drop below 20 degrees F
- Your outdoor faucets are on the north side of your house (less sun exposure)
- You do not have frost-free faucets (more on this below)
Slip the cover over the faucet and tighten the strap. That is it.
What If You Have Frost-Free Faucets?
Frost-free faucets (also called freeze-proof or anti-siphon hose bibs) have a long stem that extends 6 to 12 inches inside the wall. The actual valve seat where water shuts off is inside the heated space of your home, not at the outdoor faucet head.
Frost-free faucets still need winterizing. Here is why: if you leave a hose connected to a frost-free faucet, the hose traps water in the faucet body outside the valve seat. That trapped water can freeze and crack the faucet body. When spring comes and you start using the faucet again, water sprays inside your wall.
Winterizing a frost-free faucet:
- Disconnect all hoses (the most important step)
- Open the faucet for 30 seconds to drain any water from the stem
- Close the faucet
- Optionally add a faucet cover for extra protection
You do not need to shut off an interior valve for frost-free faucets unless you have reason to believe the faucet is damaged or not functioning properly. The design handles freezing temperatures on its own, but only if no hose is attached.
Sprinkler System Winterization
If you have an in-ground sprinkler system, it needs separate winterization that goes beyond outdoor faucets. Sprinkler lines are buried only 6 to 12 inches deep in most installations, well within the frost line in cold climates.
Professional blowout: Most sprinkler systems need to be blown out with compressed air to remove all water from the lines. This typically costs $75 to $150 and takes about 30 minutes. An irrigation company uses a large air compressor to force water out of every zone.
Do not skip this. Repairing a single cracked sprinkler line costs $200 to $500. Replacing multiple cracked zones after a freeze can run $1,000 to $3,000.
When to schedule: Book your sprinkler blowout at least 2 to 3 weeks before the average first freeze date in your area. Irrigation companies get very busy in October and November, and waiting too long can mean a frozen system before they can get to you.
What to Do If Your Pipes Freeze Anyway
Even with proper winterization, pipes can freeze during extreme cold snaps. Here is what to do:
If You Catch It Before a Burst
- Open the affected faucet to relieve pressure
- Apply gentle heat to the frozen section using a hair dryer, heat lamp, or towels soaked in hot water
- Never use an open flame, propane torch, or blowtorch on frozen pipes. This is a fire hazard and can cause the pipe to burst from rapid expansion.
- Work from the faucet end backward toward the frozen section so melting water can flow out
- Once flow is restored, check for any cracks or leaks
If a Pipe Has Already Burst
- Shut off the main water supply immediately
- Open faucets to drain remaining water
- Turn off electricity in any area where water is near electrical outlets or panels
- Call a licensed plumber
- Document the damage with photos for your insurance claim
- Contact your homeowners insurance company
What Does Frozen Pipe Repair Cost?
| Repair Type | Typical Cost |
|---|---|
| Thawing a frozen pipe (no burst) | $100-$300 |
| Repairing a single burst pipe (accessible) | $500-$1,500 |
| Repairing a burst pipe inside a wall | $1,000-$4,000 |
| Water damage restoration (moderate) | $2,000-$8,000 |
| Water damage restoration (severe, structural) | $8,000-$25,000+ |
The average insurance claim for water damage from frozen pipes runs approximately $10,000 to $15,000 when you factor in both plumbing repair and property damage. A 15-minute winterizing job suddenly looks like the best investment you will make all year.
Regional Winterizing Timeline
When you should winterize depends on where you live:
| Region | Winterize By | Average First Hard Freeze |
|---|---|---|
| Northern states (MN, WI, MI, NY) | Mid-October | Late October |
| Upper Midwest (IL, OH, IN, PA) | Late October | Early November |
| Mid-Atlantic (VA, MD, DC, NC) | Early November | Mid-November |
| Southern states (GA, AL, MS, TN) | Late November | Early December |
| Deep South (FL, TX Gulf Coast, LA) | Mid-December | Late December (if at all) |
| Pacific Northwest (WA, OR) | Late October | November |
| Mountain West (CO, UT, MT) | Early October | Mid-October |
If you are not sure about your area, search “first frost date [your zip code]” for historical averages.
Spring Reactivation: How to Turn Everything Back On
When winter is over and overnight temperatures are consistently above 32 degrees F:
- Close all outdoor faucets that you left open for the winter
- Close any bleeder caps you opened
- Slowly open the interior shutoff valves (turn them on gradually to avoid water hammer)
- Go outside and open each faucet briefly to check for leaks
- Inspect the faucet body and the pipe inside the wall for any signs of cracking or damage
- Reconnect hoses once you are confident everything is intact
If you find a leak during spring reactivation, shut off the interior valve and call a plumber. Catching a hairline crack now is far cheaper than discovering it after full water pressure has been running through it.
