Before you pick up the phone

How to choose a plumber starts with knowing what you need

A clear description of the problem gets you a clearer answer, and makes it easier to spot someone guessing.

Name the symptom, not the fix

Callers often ask for a particular repair, such as a new valve or a full replacement, when what they really have is a symptom. Describe what you see and hear: which fixture, since when, whether it is hot or cold, whether water is on the floor. A good plumber will ask follow-up questions and may want to see the problem before naming a solution. Be wary of anyone who diagnoses a major job entirely over the phone without asking anything.

Also decide how urgent it is. Water spreading across a floor, sewage coming up a drain or a gas smell cannot wait for a week of comparison shopping. A slow drain, a dripping faucet or a toilet that runs can. Your approach to choosing differs accordingly.

Urgency first
SituationHow fastHow to choose
Water spreading, burst pipeRight nowClose the main, then call a 24/7 number
Sewage backupSame dayStop using water, call someone with a camera and drain tools
Gas smellLeave firstCall the gas utility from outside, a plumber after clearance
No hot waterWithin a day or twoAsk about repair versus replacement
Slow drain, dripping tapThis weekCompare two or three, ask how they scope the job
Remodel or repipeWeeks aheadCollect written estimates and compare the details
Match your approach to the urgency

Information to have on hand

A plumber can give a better first answer when you can tell them the basics. Note the age and type of the fixture or heater, where the shutoff is, and whether anything has changed recently. Photos of the problem and of any labels on the equipment save time and help avoid a wasted trip.

Have this ready
  • What happensPlain description, when it started.
  • WhereRoom, fixture and which taps are affected.
  • Equipment detailsBrand and age of the heater or fixture, from the label.
  • What you triedPlunging, resetting, closing a valve.
  • AccessWhere the main valve and panel are, and any pets or alarms.
Checking a plumber out

How to choose a plumber: questions that separate good from guesswork

You are not trying to catch anyone out. You are trying to learn how they work.

Questions and what the answers tell you

The state registration of a plumber is a matter of public record, so you can check it yourself with the state contractor lookup before anyone starts. Ask the city building department if you are unsure what rules apply to your job. When you call us, a person answers, and you can ask any of these questions about how a visit would go. Ask about pricing when you call.

How the bill is built

How to choose a plumber and compare what plumbers charge

Plumbers bill in several ways, and the cheapest-looking number is not always the best value.

Common ways of pricing a job

Some companies quote a flat price for a defined job, such as swapping a toilet or replacing a faucet. Others bill for time and materials, and some charge a service call fee for the trip and the diagnosis, then price the repair after they find the cause. None is wrong. What matters is that you know which one you are being offered before work starts, and what could change the number.

Pricing styles
Pricing styleStrengthWatch for
Flat price for a defined jobYou know the total up frontWhat is excluded: parts, access, disposal
Time and materialsFits unclear jobsNo cap; ask for a not-to-exceed figure
Service call plus repairSeparates diagnosis from fixWhether the call fee is credited to the repair
Written estimate for a big jobAllows comparisonCompare scope, not only the bottom line
Pricing methods

What moves the price

Many things change what a plumbing job costs, and none of them is the plumber’s whim. Access matters: a pipe behind a finished wall costs more to reach than one in an open basement. Parts and materials vary widely by quality. The size of the job and how many trips it needs also change the total, and so can any city rules that apply, which the city building department can explain. Ask the plumber to tell you which of these apply to your job.

Cost drivers
  • AccessOpen basement versus finished wall or slab.
  • Parts and materialsBasic versus higher-grade fixtures and pipe.
  • ScopeA repair versus a replacement.
  • Time and difficultyA quick fix versus a long, hard job.
  • Cleanup and restorationWho patches the drywall or sod afterward.
Comparing estimates

How to compare plumbing estimates side by side

Two numbers for the same job often describe different jobs. Line them up before you decide.

  1. Ask for the scope in writing

    Each estimate should name the work, parts, and what is excluded.

  2. Compare like with like

    Same fixture, same pipe type, same level of cleanup.

  3. Ask about unknowns

    What happens if the wall holds something unexpected? Who decides, and what does it cost?

  4. Check timing

    When can the work start, how long will it take and will water be off?

  5. Ask what happens afterward

    How are problems handled if the repair fails, and who do you call?

  6. Do not choose on price alone

    A very low figure may leave out parts or cleanup. A high figure may include extras you do not need.

A worked example helps. Say two companies are asked to replace a leaking kitchen faucet. One estimate lists a basic faucet, labor and disposal. The other lists a higher-grade faucet, new supply lines, a shutoff valve and cleanup. The second number is higher, but it covers parts the first leaves out. Neither is wrong, and the only way to see the difference is to read the scope line by line and ask each plumber what is and is not included.

Be careful with pressure to sign on the spot

A plumber who insists you must decide this minute, or who asks for a large payment before any work begins, is a reason to slow down. Reasonable companies give you time to read the estimate.

Warning signs

Red flags when you hire a plumber

Most plumbers are straightforward. These patterns are the ones that go wrong.

Behavior to watch for

Be cautious of unmarked vehicles with no business name, a price that changes once the work starts without a reason you understand, pressure to replace something that was not part of the original problem, and a plumber who will not put anything in writing. A company that cannot tell you its address or who owns it deserves a second look.

Slow down if
Red flagWhy it matters
No written estimate or scopeNothing to refer to if there is a dispute
Large cash payment up frontLeaves you with little recourse
Refusing to say where they are basedHard to reach afterward
Pushes the most expensive option firstMay not match the real problem
Cannot explain the causeMay be guessing
Condemns everything on the first visitAsk for evidence: photos, camera footage
Signs to slow down

Green flags

The reverse also holds. A plumber who asks questions, explains the cause, shows you the part or the camera picture, tells you what is urgent and what can wait, and puts the plan in writing is behaving the way a careful tradesperson should. If something is not clear, they explain it again without annoyance.

Good signs
  • Explains the causeShows you the part or the camera footage.
  • Separates urgent from optionalTells you what can wait.
  • Gives optionsRepair or replacement, with reasons.
  • Writes it downScope and price before work.
  • Answers calls afterwardA way to reach someone if there is a problem.
In an emergency

How to choose a plumber when it is an emergency or a Minnesota winter night

When water is on the floor you do not have time to compare, but you can still ask the right things.

What to ask in a hurry

Close the main valve first, since that buys you time. Then ask three things on the phone: can someone come today, how will the price be explained before work starts, and what will they do first. A company open at all hours, with a person who answers, is a good start. In deep winter, when frozen pipes, failed furnaces and backed-up drains all hit together, schedules fill, so call early rather than waiting for things to worsen.

Emergency calls
QuestionWhy ask it
Can someone come today?Tells you whether help is actually available
Will you explain the price before work starts?No surprises after the fact
What is the first step?Reveals whether they will find the cause before fixing
Is the call open 24/7?Winter failures do not follow office hours
Four questions for a hurry

For a leak or burst, see what to do when a pipe bursts. If the problem is a freeze, see how to prevent frozen pipes or call an emergency plumber. For a 24/7 line, a 24 hour plumber is available too.

After the job

Before the plumber leaves, test the repair with them: run the tap, flush the toilet, look at the joint. Ask for an invoice that describes the work, the parts and the date. Keep it with your records, since it helps with insurance (see our guide to insurance and plumbing leaks) and with a future sale.

Before they leave
  • Test it togetherRun fixtures, look for drips.
  • Get an itemized invoiceWork, parts, date.
  • Ask about aftercareWhat to watch for in the next few days.
  • Keep the old part if usefulEvidence of what failed.
  • Save the numberIn case the problem returns.
When to call

When to call a plumber right away

Comparing options is fine for most jobs. For these, call now.

  1. Water is spreading or a pipe has split

    Close the main valve and call.

  2. Sewage is backing up

    Stop using water and call.

  3. No water or no heat in winter

    A frozen line or a failed heater needs quick action.

  4. You smell gas

    Leave, call the utility from outside, then book a plumber for the repair.

Questions

Questions about choosing a plumber

How to choose a plumber for a repair?

Describe the problem, ask how they find the cause, get the scope and price in writing, and look up their state registration. Compare two estimates on the same job if it is not urgent. In an emergency, ask for the first step and how the price will be explained.

What questions should I ask a plumber before hiring?

Ask who will do the work, what is included in the price, what could change it, how they handle a repeat problem and whether you can have the scope in writing. Ask for proof of liability coverage.

How do plumbers charge for a job?

Some quote a flat price, others bill time and materials, and some charge a service call plus repair. What matters is knowing which applies and what could change the number. Ask about pricing when you call.

Is the cheapest plumber the best choice?

Not necessarily. A low figure may leave out parts, cleanup or access. Compare the scope of each estimate, not just the total.

How do I check that a plumber is registered with the state?

Use the state’s contractor lookup, which is public. Ask the plumber for their number and compare it. The page on plumbing repair describes how a visit usually runs.

Should I get more than one estimate?

For planned jobs, yes. Make sure the scope and parts match so the comparison is fair. For emergencies, close the main valve and call quickly.

What are red flags when hiring a plumber?

Pressure to sign immediately, no written scope, a large payment before work starts, no way to reach them afterward and a diagnosis with no explanation are reasons to slow down.

Why do plumbing prices differ so much?

Access, parts, scope, time and cleanup all change the total. A pipe behind a wall costs more to reach than one in an open basement, and fixture quality varies.

How do I find a plumber at night or on a weekend?

Look for a 24/7 line where a person answers. We are open 24/7 and same-day service is available. See the page on emergency plumber service.

Do I need to be home during the work?

Usually someone should be present to show access, approve changes and test the result. Tell the plumber about pets, alarms and where the main shutoff is.
