McKinney Plumber Guide: Winter Pipe Prep
A McKinney plumber visit before the first hard freeze is the simplest way to find weak spots in your pipes while the weather is still mild. Cover outdoor faucets, insulate exposed lines, find your shut-off valve and check the water heater now, then call to be connected with a local provider for anything you are unsure about.

- At DFW Airport, the average first freeze is November 22 and the average last freeze is March 12, so McKinney winter prep belongs in early November.
- The Texas Department of Insurance warns that policies might not pay for frozen pipe damage if you did not take steps to protect your pipes.
- If pipes freeze, TDI says to turn off the water at the shut-off valve.
- Dallas Water Utilities says most homes have a private cut-off valve, typically near an outside faucet close to the house.
- Texas plumbers are licensed by the Texas State Board of Plumbing Examiners (TSBPE), and anyone can look up a license online.
Why should I call a McKinney plumber before winter starts?
Calling a McKinney plumber before winter lets a provider check the pipes most likely to freeze while the weather is calm and the house is dry. Fall visits are about prevention: outdoor faucets, pipes in the attic or garage, the water heater and the main shut-off valve.
Most freeze damage in North Texas comes from a handful of weak spots, not from every pipe in the house. A provider can point those spots out, explain what needs attention and what can wait, and give you a written quote before any work. Call to be connected with a local provider.
Which pipes in a McKinney home are most likely to freeze?
The pipes most likely to freeze in a McKinney home are the ones outside the heated space: outdoor hose bibs, lines in the attic, pipes along exterior walls, and supply lines in the garage. Irrigation backflow devices in the yard are exposed too.
- Hose bibs: water can freeze in the line just inside the wall, even when the faucet looks fine.
- Attic lines: many homes in this area run water lines overhead, where winter air reaches them.
- Garage pipes: water heater lines and laundry hookups in an unheated garage are exposed on cold nights.
- Exterior walls: kitchen and bathroom sinks on outside walls can freeze inside the cabinet.
What is on a winter plumbing checklist?
A winter plumbing checklist covers four things: shut-off valve, outdoor faucets, exposed pipes and the water heater. Do the easy parts yourself and ask a provider to look at anything that leaks, sticks or is hard to reach.
- Find the main shut-off valve and make sure it turns.
- Disconnect garden hoses and cover each outdoor faucet.
- Insulate exposed pipes in the attic, garage and crawl spaces.
- Shut off and drain the irrigation system or backflow device if you know how.
- Look for drips, rust or moisture around the water heater.
- Seal gaps where pipes pass through exterior walls.

How do I find and test my main water shut-off valve?
Most homes have a private cut-off valve near an outside faucet close to the house, according to Dallas Water Utilities, and older homes may have a buried valve with an L-shaped iron handle. Find yours now, before you need it in a hurry.
Turn it slowly to the off position and check that a faucet inside stops flowing, then turn it back on. If the valve is stuck, leaks around the stem or will not close all the way, do not force it. That is a good reason to call and be connected with a provider. See the main water line repair page for more on supply line problems.
Should I drip my faucets when it freezes in McKinney?
Yes, letting faucets on outside walls drip during a hard freeze can help, because moving water is slower to freeze. Open both hot and cold slightly on sinks that sit against exterior walls, and open the cabinet doors so warm air from the room reaches the pipes.
Keep the heat on, even if you leave town, and keep the garage door closed. Remember that dripping helps the lines it reaches. It does not protect a hose bib or an attic line that has no faucet open downstream, so cover and insulate those first.
What should I check on my water heater before winter?
Before winter, check your water heater for water around the base, rust on the tank or fittings, and popping or rumbling sounds. Cold incoming water makes the heater work harder in winter, so small problems often show up then.
If the heater sits in the garage, look at the supply lines above it and insulate any exposed pipe. Keep storage boxes away from the unit. If you see a leak, turn off the cold water supply to the tank and call to be connected with a provider. Learn more on the water heater repair page.
What do I do if a pipe freezes or bursts this winter?
If a pipe freezes or bursts, turn off the water at the main shut-off valve right away. The Texas Department of Insurance gives the same advice. Then turn off power to any wet area near outlets or appliances, and take photos before cleanup.
A frozen pipe that has not split may thaw on its own once the house warms up. Never use an open flame to thaw it. If water starts spraying when the line thaws, close the main valve and call to be connected with a local provider. Read more about burst pipe repair in McKinney.
Does home insurance cover frozen pipes in Texas?
It depends on your policy, and protection steps matter. The Texas Department of Insurance warns that home and renters policies might not pay for frozen pipe damage if you did not take steps to protect your pipes, and that flood insurance does not pay for burst-pipe damage.
Many policies treat sudden damage differently from gradual leaks, so check your policy and document everything. Keep notes and photos of your winter prep, such as covered faucets and insulated pipes, along with any repair paperwork.
What happens during the visit?
A winter plumbing visit follows three steps: inspection, an explanation of your options, and a written quote before any work starts. The provider walks through the exposed pipes, valves and water heater, then tells you in plain words what they found.
Ask which items matter most before the first freeze and which can wait. Ask for the quote in writing and whether any job needs a city permit and inspection. You can also ask for the name of the company's Responsible Master Plumber and check the license with TSBPE.
Winter weather facts for McKinney and nearby towns
At DFW Airport, the average first freeze is November 22 and the average last freeze is March 12, based on records going back to 1898. That gives McKinney, Prosper, Allen and Frisco a freeze season of nearly four months.
Hard freezes are rare but serious here. During the February 2021 winter storm, DFW Airport fell to -2 degrees on February 16 and stayed below freezing for 139 hours in a row. Insurers reported 21,715 claims in Collin County from that storm, across all insurance lines.
Soil matters too. McKinney sits in the Blackland Prairie, where the Houston Black clay can "shrink and swell markedly with changes in moisture content." If you live outside McKinney, see the Prosper and Allen pages, or the full service areas list.

Questions people ask
When should I call a McKinney plumber to get my house ready for winter?
Early November is a good time, before the average DFW first freeze on November 22. Call to be connected with a local provider while the weather is still mild.
Do I really need to cover my outdoor faucets in North Texas?
Yes, covering outdoor faucets is one of the simplest winter steps. Disconnect the hose first, then fit an insulated cover over each faucet.
Why do I have to take the garden hose off before a freeze?
A connected hose holds water that can freeze and push back into the faucet and the pipe inside the wall. Remove it, drain it and store it.
What temperature makes pipes freeze in Texas?
Exposed pipes are at risk once outdoor temperatures drop below freezing for several hours. Wind, attic location and how long the cold lasts all play a part.
Is it worth insulating the pipes in my attic in McKinney?
Yes, attic and garage lines are among the most exposed in local homes. Foam pipe sleeves are a common first step, and a provider can check hard-to-reach runs.
Should I leave my cabinet doors open on freezing nights?
Yes, for sinks on exterior walls. Open cabinets let warm room air reach the pipes, which helps along with a slow drip.
Should I drip hot water or cold water when it freezes?
Drip both if the faucet has two handles, or set a single handle to the middle. Both the hot and cold lines can freeze.
What should I do with my sprinkler system before winter?
Shut off the irrigation water supply and drain the system if you know how. Exposed backflow devices can be wrapped with an insulated cover.

Incoming water is colder in winter, so the heater has to work harder. A sudden change can also point to sediment or a part wearing out.
