Tulsa winters are usually mild, which is exactly why frozen pipes catch people off guard. Most of the year, a pipe in an outside wall or a crawlspace never gives trouble. Then a hard freeze settles in for several days and a hidden line splits. This guide covers how cold Tulsa actually gets, what happened in the big freezes of 2011 and 2021, what City ordinance says about protecting pipes, how to prevent freeze damage and what to do if a pipe freezes or bursts.
How cold does Tulsa get?
NOAA's 1991–2020 climate normals for Tulsa International Airport show:
- About 72 nights a year at or below 32 °F.
- A January average low of 28.0 °F.
- A median first fall freeze on November 4 and a median last spring freeze on March 31.
So freezing nights are routine from November through March. A single cold night rarely freezes indoor plumbing. The bigger risk is a stretch of days that stay below freezing, when cold has time to work into attics, garages, crawlspaces and exterior walls.
Tulsa's big freezes: February 2021 and February 2011
February 2021. According to the National Weather Service office in Tulsa, the city had 10 consecutive days below freezing. Tulsa set record lows of −7 °F on February 15 and −13 °F on February 16, and the high of just 5 °F on February 15 was the coldest February maximum temperature on record.
February 2011. The blizzard of January 31 to February 1, 2011 dropped 14.0 inches of snow on Tulsa, the city's heaviest single storm on record. A few days later, on February 10, Tulsa hit −12 °F.
Events like these are rare, but they are the reason to prepare every fall. Frozen and burst pipes are a general risk in any extended hard freeze, especially in homes with plumbing in unheated spaces.
Whose job is it to protect the pipes?
Yours. City ordinance (Tulsa Revised Ordinances, Title 11-C) says the service pipes and connections within private premises must be kept in good repair and protected from freezing by the owner at the owner's expense, and that the owner or occupant is responsible for damage from leaks and breaks. In Tulsa, the sewer and water lines from your house to the City's connection are generally the homeowner's responsibility. Our guide to Tulsa sewer line responsibility covers the details. This is general information, not legal advice; check the current ordinance with the city.
Which pipes freeze first?
- Outdoor hose bibs (spigots) and garden hoses left connected.
- Pipes in exterior walls, especially on the north side of the house.
- Lines in attics, garages and crawlspaces.
- Sink supply lines inside cabinets on outside walls.
- Irrigation piping and the backflow preventer. City ordinance requires a backflow preventer on residential irrigation systems in Tulsa, and it usually sits above ground where it is exposed.
How to prevent frozen pipes before a hard freeze
- Find your main shutoff valve now, before you need it, and make sure it turns. Show everyone in the house where it is.
- Disconnect garden hoses and cover outdoor spigots with insulated covers.
- Shut down and drain the irrigation system for the season, following the manufacturer's directions, and protect the backflow preventer.
- Insulate exposed pipes in the attic, garage and crawlspace with foam pipe sleeves. Close crawlspace vents and garage doors during a freeze.
- Open cabinet doors under sinks on outside walls so warm room air reaches the pipes.
- Let a faucet drip on the coldest nights, ideally one on an outside wall. Moving water is harder to freeze.
- Keep the heat on, even if you travel. Ask someone to check the house during a long freeze.
- Get small leaks fixed before winter. A slow leak in a cold wall is a weak point. See the leak detection page if you suspect one.
What to do if a pipe freezes
Signs of a frozen pipe include a faucet that gives only a trickle, frost on an exposed pipe, or no water at one fixture while others work.
- Open the affected faucet so water can flow once the ice starts to melt.
- Warm the pipe gently, starting nearest the faucet, with a hair dryer, a space heater kept a safe distance away, or warm towels.
- Never use an open flame, torch or propane heater on a pipe.
- If you cannot find or reach the frozen section, or it is inside a wall, call a plumber. A pipe can be cracked even before it leaks.
What to do if a pipe bursts
- Shut off the main water valve first. This is the single most important step.
- If water is near outlets, appliances or the electrical panel, stay clear and keep safety first.
- Open a faucet at the lowest point in the house to drain the remaining water out of the lines.
- If the burst is on hot water piping, consider turning off the water heater (gas to "pilot" or the breaker for electric) until a plumber looks at it.
- Take photos for your insurance company and move belongings out of the water.
- Call a plumber. The emergency plumber page explains what to expect.
If you smell gas at any point, leave the house first, then call 911 and Oklahoma Natural Gas at 800-458-4251.
What freeze repairs typically cost
Burst pipes tend to happen at night and on weekends, when rates are higher. These are ranges from published cost guides, not prices from us or any contractor:
| Item | Typical range |
|---|---|
| Service call / trip fee | $50–$200 (often includes the first hour) |
| Plumber hourly rate | $45–$150/hr nationally; $45–$165/hr in Tulsa (Thumbtack) |
| Emergency / after-hours | $100–$350/hr, or a $150–$250 after-hours fee |
| Water heater repair | $150–$700 tank; $300–$1,300 tankless |
| Whole-house repipe (~2,000 sq ft) | $2,300–$5,100 |
Permit fees and old-unit disposal are often billed separately. Your written quote from the contractor you choose is what counts.
Many Tulsa plumbers offer after-hours service, usually at a higher rate. More ranges are on our Tulsa plumbing cost page. If a freeze damaged ythe water heater, that page covers repair-versus-replace questions.
Hiring help after a freeze
After a widespread freeze, many people are looking for plumbers at once. Before you hire, ask for the contractor's Oklahoma plumbing license number and check it on the Construction Industries Board's "Are They Licensed?" page, ask whether they are registered with your city, and get the price in writing. Our guide on checking an Oklahoma plumber license walks through it. The same advice applies in the suburbs, from Owasso to Sapulpa.
