What does an emergency plumber cost in Knoxville?
Expect a call-out fee plus a higher after-hours rate. The only dated Knoxville figure we found is for the whole burst pipe repair; the fee and hourly ranges below are national.
An after-hours plumber visit is usually billed as a call-out fee of about $100–$350 plus labor at 1.5 to 3 times the normal rate, according to national published estimates. For the repair itself, the one published Knoxville range we found puts a burst pipe at $748–$2,991.
Local call line opening soonThe three ways the bill is built
- Call-out (trip) fee. Charged for showing up, whatever the repair turns out to be. Ask whether it is credited toward the work.
- Hourly labor. The clock may start at dispatch or at your door, and there may be a minimum number of hours. Ask which.
- Flat rate. One price for the job, quoted after the plumber sees it. You know the total before work starts, but you can't compare it by the hour.
Parts are extra in most cases. None of these numbers include drying out what got wet — that's a separate job, covered in water damage restoration cost in Knoxville.
Published ranges: Knoxville vs. national

| Burst pipe repair (whole job) | $748–$2,991 | Knoxville |
| Water heater repair | $112–$561 | Knoxville |
| Water heater installation | $767–$1,917 | Knoxville |
| Emergency call-out fee | $100–$350 (Forbes average $225) | National |
| Emergency hourly rate | $100–$500, about $170 typical; up to $600 on holidays | National |
| After-hours multiplier | 1.5×–3× the normal rate | National |

Knoxville rows: Today's Homeowner, updated Feb 2025. National rows: Angi, HomeGuide (which lists a narrower $100–$350 hourly range) and Forbes. These are published estimates, not quotes, and we found no dated Knoxville-specific figure for the call-out fee or hourly rate.
How the pieces add up (national figures, for illustration): a $225 call-out fee plus two hours at $170 is $225 + $340 = $565 before parts. At the top of the hourly range, the same two hours cost $225 + $1,000 = $1,225.
What moves the price
- Time of day. Nights, weekends and holidays sit at the upper end of the multiplier.
- Access. A pipe you can reach under a sink is quicker than one in a crawlspace or behind a finished wall. No published source we found prices crawlspace work separately, so ask for it in the quote.
- Parts. A short section of pipe is cheap; a failed water heater is not.
- Demand. During the December 2022 freeze, KUB took more than 1,000 calls about frozen or broken pipes in a week, and Knox News reported one plumber quoting roughly a three-hour wait. When every crew in town is booked, there is little room to shop around.
Seven questions before they dispatch
- What is the call-out fee, and is it credited toward the repair?
- Hourly or flat rate? If hourly, when does the clock start and is there a minimum?
- What is the after-hours rate compared with the daytime rate?
- How long until someone arrives?
- Will I get a written price before work begins?
- What is your Tennessee license number?
- Does this job need a permit, and who pulls it?
How Tennessee plumbing licenses work
The Board for Licensing Contractors, part of the Tennessee Department of Commerce & Insurance, requires a contractor license for projects of $25,000 or more. Plumbing work under that amount falls under the Limited Licensed Plumber (LLP) license — which is what almost any emergency repair would be.
Get the number on the phone and look it up through the license search on the Board's page at tn.gov. Locally, Knox County Code Administration handles LLP affidavits (865-215-2325), and Knoxville's Plans Review and Inspections office is at 865-215-3669. We are a referral service and can't verify a provider's license for you, so do this check yourself.
Can it wait until morning?
It can usually wait if the water is fully off, nothing wet is near outlets or the electrical panel, and the water was clean supply water. Waiting moves you from the after-hours rate to the normal one.
To make it safe overnight:
- Close the main shut-off and leave faucets open. If you can't find the valve, KUB has said it will help customers locate it; its 24-hour line is 865-524-2911.
- Cut power to the wet area only if you can reach the panel from a dry spot.
- Photograph the damage, then start mopping and airing out. The EPA says to dry water-damaged areas within 24–48 hours to prevent mold.
- Frozen but not burst? Keep the faucet open and warm the pipe with a space heater or hot towel — never an open flame.
One caution: shutting off the water also disables fire sprinklers, if your home has them.
It can't wait if you can't stop the water, water is reaching wiring or the panel, sewage is coming up, or the house would have no heat on a freezing night. For the full first-hour sequence, see what to do when a pipe bursts and the Knoxville burst pipe guide.
