Plumbers: what to ask, what it costs, and one number to call
Updated June 2026 · By the Mobile Phonebook editorial team · How we research pricing
If it's happening right now: do this
- Water flowing where it shouldn't? Close the main shutoff valve, usually where the line enters the house or at the meter. Every minute of flow is drywall and flooring.
- If it's one fixture, use its own valve instead (under the sink, behind the toilet) and keep water to the rest of the house.
- Water near outlets or appliances? Cut power to that area at the breaker if you can do it safely.
- If water already soaked floors, walls, or ceilings, you may need two calls. The plumber stops the source, a restoration company handles drying, and your insurer's claim line should hear about it early.
- Then call the number on this page. Say exactly what was leaking and that the water is off. A stopped leak often turns an emergency rate into a next-morning rate.
Plumbers handle the water and gas lines that run your house: burst and leaking pipes, clogged drains and sewer lines, water heaters, toilets, faucets, garbage disposals, sump pumps, and gas line work. Calls split between genuine emergencies (water spraying somewhere it shouldn't) and scheduled work like replacing a tired water heater or fixing the slow drain that finally quit draining.
Plumbing pricing confuses people more than the work does. Service fees, dispatch fees, flat-rate books, hourly rates, after-hours multipliers. Every shop structures it differently, and the difference between a fair bill and an inflated one often comes down to two or three questions you ask on the phone before anyone rolls a truck.
What should you have ready before you call?
- What's happening, where, and whether water is actively flowing (if so, shut the main off first)
- Whether it's one fixture or the whole house. One slow drain versus every drain backing up points to very different problems.
- Age and type of your water heater (tank/tankless, gas/electric); it's on the label
- Photos of the leak, the fixture, or the model and serial plates
- Whether you've had this problem before and what was done last time
- Where your main shutoff valve and cleanouts are, if you know
- Your timeline, because middle-of-the-night emergency rates and tomorrow-morning rates can differ a lot
What should you ask before hiring? The 8-question script
This is your script. Nobody expects you to be an expert. Sound like someone who asks the right questions, and anyone good will answer all of these without flinching.
This is the first money question, and the answer varies shop to shop. 'Waived with repair' is common and fair. Know the number before the truck rolls.
Either model is fine. What matters is a firm quote up front. 'We'll see when we get in there' with no number attached is how bills surprise people.
Apprentices under supervision are normal for routine work, but gas lines, major repairs, and anything permitted should involve a licensed plumber. Ask how licensing works in your state.
An honest dispatcher will tell you when shutting the water off and waiting saves you hundreds. If everything is an emergency to them, that's a tell.
Basic drain clearing is one price. Main-line work, camera inspections, and hydro jetting are others. Know where the quoted price stops and what triggers the next tier.
The advertised unit price isn't the installed price. Pan, valves, venting, expansion tank, and permit can add hundreds. Get the all-in number.
Water heaters, gas work, and repipes usually require permits. A plumber who shrugs at permits is leaving you holding the liability at inspection or resale time.
Parts carry manufacturer warranties. Labor warranties (90 days to several years depending on the job) show the company stands behind its installs.
How much do plumbers cost in 2026?
Expect a service call fee plus either a flat-rate menu price or hourly labor ($75-$200/hr) and parts. After-hours work runs a premium. Typical 2026 national ranges:
| Typical job | National range | What moves the price |
|---|---|---|
| Service call / dispatch fee | $50 – $150 | Often credited toward the repair; higher after hours |
| Faucet, toilet fill valve, or disposal repair | $150 – $450 | Flat-rate shops sit at the high end |
| Toilet replacement (installed) | $250 – $700 | Plus the toilet itself if you don't supply it |
| Drain clearing (tub, sink, toilet) | $130 – $400 | Main sewer line snaking runs higher |
| Main line camera inspection | $150 – $500 | Sometimes bundled free with jetting, so ask |
| Hydro jetting | $300 – $1,000 | For grease and root buildup that snaking can't fix |
| Tank water heater replacement (installed) | $1,200 – $3,500 | Gas vs. electric, code upgrades, permit |
| Tankless water heater (installed) | $2,500 – $6,500 | Gas line and venting upgrades drive the spread |
| Burst pipe repair | $200 – $1,500+ | Access is everything; an open wall is cheap, a slab leak isn't |
These are typical 2026 U.S. ranges for planning purposes; your market, season and job specifics can land outside them. Always get the price for your job confirmed on the call and in writing. Ranges compiled June 2026 from national cost data and industry sources (methodology).
When you don't need to call anyone
We get paid when you call, so take this section as seriously as we do. Sometimes the honest answer is that you can handle it yourself or fix it cheaper first:
- A single slow drain usually yields to a $10 hand auger or a plastic hair-snake tool before it justifies a service call. Skip the chemical openers, though. They damage pipes and make the eventual pro visit harder.
- Running toilet? A flapper or fill valve is a $10–25 part, and the instructions are under the tank lid. It's the most common plumbing 'repair' there is.
- A dripping faucet usually wants a new cartridge. Find your model, watch the video, save the call-out fee.
- Weak flow at one faucet is often just a clogged aerator. Unscrew the tip and rinse it.
- Where DIY ends: gas water heater connections, sewer line backups, and anything that requires opening a wall.
How the plumbing business works
Almost every plumbing company charges something just to show up. It goes by service call, dispatch, or trip fee, and typically runs $50-$150. Some waive it if you approve the repair; some don't. After-hours, weekend, and holiday calls usually carry a premium, sometimes 1.5-2x. Always ask three things: what's the fee to come out, does it apply toward the work, and what's the after-hours markup? Those answers tell you a lot about the shop.
Then there's flat-rate versus hourly. Most larger residential shops use flat-rate 'menu' pricing. The tech looks at the job, opens a price book (usually on a tablet), and quotes a fixed price for that task regardless of how long it takes. Flat rate protects you from a slow tech but bakes in healthy margins, which is how a 30-minute fill-valve swap ends up at $350. Smaller shops and independents more often charge hourly ($75-$200/hr depending on market) plus parts. Neither model is a scam. You just want to know which one you're in and get the number before work starts.
Who shows up matters. Larger companies send a mix of licensed plumbers and apprentices, and some heavily commissioned shops pay techs on what they sell. That's where aggressive upselling comes from: the drain call that turns into a whole-house repipe pitch. There's a real difference between a tech mentioning your water heater is 14 years old (useful) and one who won't fix the small thing without quoting the big thing (sales pressure).
For big-ticket items like water heater replacement, sewer line work, or repiping, treat it like any major purchase. Get the diagnosis, then get two or three quotes. Sewer line replacement especially, since camera findings can be interpreted differently and trenchless options vary by company. Any reputable plumber will put the diagnosis in writing or share the camera footage so you can shop it.
Red flags & good signs
Red flags
- No price until after the work is done. Always get the number first, in writing or on the work order.
- A simple clog call that becomes an immediate whole-house repipe or sewer replacement pitch, without camera footage you can see
- Refusing to show you the failed part or the camera video that justifies a big-ticket recommendation
- Quotes for sewer work measured in vague 'sections' instead of footage, scope, and method
- Pressure to decide on a $5,000+ job on the spot 'because the price goes up tomorrow'
- No license number on the truck, invoice, or website in states that require one
- Demanding full payment up front for multi-day jobs
Good signs
- Clear service-fee policy stated on the phone before dispatch
- Written quote before work starts, with the flat-rate or hourly basis explained
- Shows you the problem, whether that's the corroded part, the camera footage, or the moisture reading
- Tells you when something can wait, or when a cheaper fix is worth trying first
- Pulls permits for water heaters and gas work without being asked
