The short answer
A licensed plumber in Austin charges $37 to $125 an hour, plus a $41 to $125 service call. Most small jobs come to $82 to $655. The big local factor is expansive clay soil that shifts with wet and dry cycles and stresses buried pipes, so slab leaks and sewer breaks are common calls.
What plumbers cost in Austin
These ranges cover labor and standard parts for a typical single-family home. They come from national cost data with the Texas cost factor applied, compared with local Austin price guides.
| Job | Austin (typical range) | US average |
|---|---|---|
| Hourly rate (licensed plumber) | $37–$125/hr | $45–$150/hr |
| Service call / trip fee | $41–$125 | $50–$150 |
| Clear a clogged drain | $82–$225 | $100–$275 |
| Install a faucet | $98–$245 | $120–$300 |
| Install a toilet | $285–$655 | $350–$800 |
| Find and fix a leak | $125–$535 | $150–$650 |
| Burst pipe repair | $410–$4,100 | $500–$5,000 |
| Sewer line repair | $410–$3,100 | $500–$3,800 |
| Gas line repair or install | $285–$1,650 | $350–$2,000 |
| Water heater, 50-gal tank, installed | $575–$2,550 | $700–$3,100 |
| Tankless water heater (gas), installed | $1,700–$4,600 | $2,100–$5,600 |
| Whole-house repipe | $3,300–$13,100 | $4,000–$16,000 |
Estimates for 2026, including labor and standard parts. Austin prices use the Texas statewide construction cost factor of 0.82 (US average = 1.00) from the U.S. Army Corps of Engineers Area Cost Factors, which have no separate Austin entry. Your quote depends on access, materials and the condition of the home.
Quotes climb toward the top of the range when the work is hard to reach, such as a leak under a slab, a water heater in an attic, or a sewer line under a mature live oak. Attic and second-story closet water heater installs, common in Northwest Austin and Cedar Park garden homes, carry a $250 to $500 surcharge for access and pan requirements, according to HomeShow.ai.
Water heater work also needs a permit, which adds fees and an inspection visit. One Austin plumbing company charges $99 to quote a water heater replacement and waives it if you hire them (Team Austin), so ask about quote fees before you book.

Why plumbing breaks the way it does in Austin
Austin sits on expansive clay, and the ground under most homes swells when it is wet and shrinks when it is dry. Pipes buried in that soil get pushed and pulled every season, so slab leaks and sewer line breaks are a normal call here.
Hard water
Austin Water's own 2025 report puts tap water at an average of 93 ppm total hardness, about 5.4 grains per gallon, ranging from 4.1 to 7.4 gpg (Austin Water). The utility's figure is the one to plan around. At that level, scale builds up inside tank water heaters, faucet cartridges and shower valves. Flushing a tank once a year and replacing the anode rod when it wears out adds years to its life.
The water comes from the Lower Colorado River through Lake Travis and Lake Austin, treated at the Handcox, Davis and Ullrich plants. Austin Water uses chloramines as its disinfectant.
Freeze events
Austin's pipes are built for heat and handle hard freezes poorly. Winter Storm Uri in 2021 damaged water infrastructure across the city, and Austin Water says its system was repaired and winterized afterward to better withstand extreme cold. Older homes still have exposed hose bibs, attic runs and garage piping that can split in a hard freeze. Insulating those lines and knowing where your shutoff is costs little compared with a burst pipe repair at $410 to $4,100.
Water heaters
A tank water heater in Austin lasts 8 to 12 years, and hard water shortens that. Most homes run a 40 or 50 gallon tank. A straightforward standard gas or electric replacement often lands in the high $2,000s to low $3,000s, and a 50 gallon power-vent replacement commonly moves into the low $4,000s, according to Team Austin. A gas tankless conversion typically prices at $4,200 to $6,800 (HomeShow.ai).
Austin's 2021 IPC amendments require a thermal expansion tank on any closed-loop system with a backflow preventer, which describes almost every home built or re-piped after 2008. The tank itself is $55 to $95 at a supply house. Installed with a tee, shutoff and strap it lands at $185 to $310. Interior installs in closets, attics or above finished ceilings need a pan with a 3/4 inch drain to an approved location.
Heat pump water heaters are another option. A 50 gallon heat pump unit runs $3,400 to $4,600 installed in Austin before incentives. Ask Austin Energy about current rebates before you buy. The federal 25C tax credit no longer helps: it covered improvements made through December 31, 2025 (IRS).
Sewer lines: yours or the city's?
In Austin, the line from your house to the city main is a private lateral, and you own it. Austin City Code Chapter 15-11 spells out that responsibility (Austin Water). The city maintains only the main in the street.
The city's plumbing code requires private laterals at no less than 2% slope, a quarter inch per foot, toward the point of disposal. The city may allow 1% slope for four to six inch pipe when 2% is not available. That slope rule matters on Austin's hills, where a short, steep lot can make a gravity line hard to run.
If a lateral fails and money is tight, Austin Housing's Private Lateral Grant Program provides free repair or replacement for eligible single-family or duplex owners with household income at or below 100% of the area median family income. The program number is 512-974-3100. Sewage on the ground complaints go to 512-972-1000, and general lateral questions to 512-972-0069.
Do you need a permit?
For most plumbing work inside the City of Austin, yes. Austin Water requires a plumbing permit, and the city says plumbing work cannot be performed without first obtaining one from Austin Development Services. That includes replacing a water heater with the same model in the same spot.
Check the current permit fee with the city before you compare bids, since some plumbers include it and others add it on top. Unpermitted work shows up in title reports when you sell.
A few city rules shape how the permit gets pulled.
- A licensed and registered trade contractor must request the plumbing permit and be assigned to it. The contractor is responsible for activating it, paying the fees, doing the work and scheduling the final inspection (City of Austin).
- Trade contractors must register with Building and Trade Contractor Services and update that registration annually with their state license information (City of Austin).
- Once a permit is activated, it expires on the 181st day if no inspection has been scheduled or received. A passing inspection extends it 180 days.
- Online ticket processing for contractor services applications currently takes 4 business days (City of Austin).
A homeowner can do their own plumbing work, but only under a Homestead Permit. You need a homestead exemption filed with the county appraisal district, and the work cannot include liquefied petroleum plumbing systems or auxiliary water systems. The permit cannot be transferred, and it can be revoked if anyone other than the person who obtained it does the work (City of Austin).
The rest of the metro
Each suburb runs its own building department, and the rules differ.
| City | Permit authority | What to know |
|---|---|---|
| Austin | Austin Development Services, Austin Water | Plumbing permit required; contractor must be registered with the city |
| Round Rock | Round Rock Building Inspection | Building permit required for plumbing system repair or replacement; one-permit system, so all contractors must be on the application; contractor registration is free (Round Rock) |
| Cedar Park | Cedar Park Development Services | All contractors must register with the city; registration is free (Cedar Park) |
| Pflugerville | Pflugerville Building Inspections | Issues plumbing permits; applications go through the CityWorks portal; residential plumbing inspections run noon to 4 pm (Pflugerville) |
| Leander | Leander Development Hub | Online permitting through the Development Hub (Leander) |
| Georgetown | City of Georgetown | Check with the city before work starts |
| Westlake | City of West Lake Hills Building and Development, 512-327-3628 | Check with the city before work starts |
Outside city limits, Travis County requires a development permit for construction and remodeling, and Williamson County handles floodplain and septic questions through its engineer's office at 512-943-3330. Williamson County has not adopted residential building code standards for unincorporated areas, so permit questions there usually come down to floodplain and septic.
How to check a plumber before you hire
Texas licenses plumbers through the Texas State Board of Plumbing Examiners. There are four license types: Tradesman Plumber-Limited, Journeyman Plumber, Master Plumber and Plumbing Inspector. There are also four registrations: Plumber's Apprentice, Drain Cleaner-Restricted, Drain Cleaner and Residential Utilities Installer.
What each one can do for you:
- A Tradesman Plumber-Limited can install, repair, service or renovate plumbing for one and two family dwellings, but only under the supervision of a Responsible Master Plumber (TSBPE).
- A Journeyman or Master Plumber can work without that residential supervision.
- A Drain Cleaner registration covers drain clearing, not pipe repair or water heaters.
Checking takes a few minutes:
- Ask for the license number and look it up in the TSBPE public license search. The name should match the business and the status should be active.
- Confirm the company has a Responsible Master Plumber. That is the person legally answerable for the work.
- Ask for the City of Austin contractor registration if the job is inside the city, since the permit cannot be pulled without it.
- Get the price in writing before work starts, with the permit listed as a line item.
- Check the complaint history. Homeowners can file a complaint with the TSBPE using its online form.
Texas plumbers must complete six hours of continuing education to renew. A license expired more than two years cannot be renewed and must be reinstated, which is a sign of a company that let its paperwork lapse.
Every plumber in the GOLDGCP network goes through a license check, insurance verification, a business and public-records check and reference calls before getting a job. You pay your pro directly, in milestones, as the work gets done. See how payment protection works before you sign anything.
Common plumbing jobs and how long they take
| Job | Typical time on site | What to expect |
|---|---|---|
| Clogged drain | 1 to 2 hours | Snaking or hydro-jetting; a camera check if it keeps coming back |
| Faucet or toilet install | 1 to 3 hours | Same-day in most cases |
| Leak detection and repair | 2 to 6 hours | Longer if the leak is under a slab |
| Water heater replacement | 3 to 6 hours | Permit, expansion tank, pan and drain, haul-away of the old tank |
| Tank to tankless conversion | 1 to 2 days | New venting, often a larger gas line, plus an electrical outlet |
| Sewer line repair | 1 to 3 days | Camera inspection first; trenchless lining when the pipe allows |
| Whole-house repipe | 2 to 5 days | Walls opened in small sections, then patched; water off during the day |
If the job is part of a larger remodel, the plumbing rough-in has to be inspected before the walls close. That is the point where a slow permit or a missing inspection costs the most time. If you are planning a kitchen or bath at the same time, the plumbing pillar page covers the trade side, and the permit drawings guide explains what the plan set needs to show.

Frequently asked questions
How much does a plumber charge per hour in Austin?
Usually $37 to $125 an hour during business hours, plus a service call of $41 to $125 that often includes the first hour. Master plumbers and after-hours calls cost more. One local price guide puts Austin master plumber labor at $135 to $185 an hour in 2026, so quotes at the top of the range are normal for complex work.
Do I need a permit to replace a water heater in Austin?
Yes. Austin Water requires a plumbing permit even for a same-size swap. The base permit is $119, and the inspection fee brings the total to roughly $140 to $189. Your plumber should pull it and arrange the inspection, which checks the venting, gas connection, relief valve, expansion tank and drain pan.
Why do so many Austin homes get slab leaks?
The soil. Austin sits on expansive clay that swells when wet and shrinks when dry, and that movement stresses pipes buried under the slab. Long dry summers followed by heavy rain are the worst pattern. A leak detection visit runs $125 to $535, and fixing the leak depends on whether the pipe can be reached from above or needs a tunnel.
Is my sewer line the city's responsibility?
No, not the private part. In Austin, the property owner is responsible for the private lateral from the house to the city main, under Austin City Code Chapter 15-11. The city maintains only the main line. If the lateral fails and your household income is at or below 100% of the area median family income, Austin Housing's Private Lateral Grant Program may cover the repair.
How do I check a plumber's license in Texas?
Look the license number up in the Texas State Board of Plumbing Examiners public license search. The name should match the business and the status should say active. Confirm the company has a Responsible Master Plumber, and if the job is inside Austin, ask for the city contractor registration number too.
Can a handyman do plumbing work in Texas?
Only limited work. Texas licenses plumbers and registers drain cleaners, and a Drain Cleaner registration covers clearing drains, not pipe repair or water heater installation. Any job that needs a permit, including water heaters and gas lines, has to be pulled by a licensed and registered trade contractor or by a homeowner under a Homestead Permit.
How hard is Austin's water?
Austin Water's 2025 report puts tap water at an average of 93 ppm total hardness, about 5.4 grains per gallon, with a range of 4.1 to 7.4 gpg. That is moderate, but it still scales water heaters and fixtures over time. Flushing the tank once a year and replacing the anode rod when it wears out is the cheapest protection.
How we calculate these prices
GOLDGCP starts from national price ranges for each job, taken from published 2026 cost guides and checked against local price guides where they exist. To get a local price, we multiply the national range by the construction cost factor for the metro from the U.S. Army Corps of Engineers Area Cost Factors (US average = 1.00). Where that table has no entry for a metro, we use the nearest listed location or the state value. For ZIP codes outside the 50 largest metros, the cost estimator uses the state's price level from the Bureau of Economic Analysis Regional Price Parities. Ranges include labor and standard materials but not unusual site conditions, so a written quote after an inspection is always the final price.
