INDIANAPOLIS GUIDE

Questions to ask before you hire a plumber in Indianapolis

The hiring page on this site is the short list: credential, written price, camera video, photos. This one is the conversation, in the order you will actually have it.

Before anyone rolls a truck

You are still allowed to be a skeptic on the phone. Start with the problem in one sentence, then ask who would come: a licensed plumber, an apprentice with a lead, or a subcontractor you have not heard of. Ask which Indiana credential covers this kind of work at your address, and how you can verify it with the office that issued it. The hiring guide stays at that altitude on purpose. We will not invent a license number format.

Ask what the visit costs if you decline the repair, and what the after-hours rule is if the call is tonight. Ask whether the figure you are about to hear includes the repair or only the diagnosis. Those pieces are why quotes diverge, which is the whole of what changes the price. Ask whether a permit is likely for this scope and who would pull it. The longer version is the permits guide.

Ask when they can be there, and what you should do until then. “Leave the main off” and “you can use the other bathroom” are different instructions. If water is active or sewage is on the floor, stop interviewing and use the emergency steps. A calm kitchen-sink question can survive a callback. A rising basement cannot.

When they arrive

Ask what they will inspect first, and what they will not touch without telling you. A drain call that starts by condemning the water heater is a scope change, not a bonus. Walk them to the symptom. Show the photos if the mess was cleaned up. Tell them what you already tried, including chemical openers. Point out the main shutoff, the panel, and pets.

Ask them to restate the problem in their own words before they price it. If their sentence does not match yours—“single lavatory” when you have a floor drain that surcharges—correct it. The rest of the quote depends on that sentence. For a repeat clog, ask whether today includes a camera and a copy of the video. That expectation is also in the drain cleaning guide.

Before they open a wall, a sewer, or a heater

This is the last cheap moment to understand the job. Ask what will be cut, whether patching is included, and what “done” looks like. Ask which parts they expect to replace and which parts they will reuse. On a water heater, ask repair versus replace, what happens to the old tank, and whether the pan, the discharge line, and the vent are in scope. Symptom background is on the water heater page; the quote should not assume you read it.

On a sewer, ask how far the cable or the camera will go, and what they will do if they find roots or a break. Digging, lining, and “we’ll know when we see it” should not share one shrug. Ask for the branch in the price: clear only, or clear plus a recorded look, with excavation as a separate approval. Ask where the cleanout is and whether they will leave you one if the line never had it and the work is large enough to justify it. If they say a cleanout is a bad idea at your house, they should be able to say why.

Ask how they want to be paid, whether the invoice will name the cause and the location, and whether warranty time is on labor, parts, or both. A warranty that starts only if you never call anyone else is a sentence you should hear before the wall is open, not after.

Before they leave

Ask them to run the fixture or the line with you there. A drain “that should be fine” is not the same as a drain you watched clear. Ask what settings they changed: a water heater temperature, a shutoff left half-closed, a valve you should not bump. Ask what to watch for overnight—a new drip at a joint they moved, a sump that should cycle, a toilet that should stop running.

Get the paperwork before the truck is running. Invoice or work order, permit number if one was pulled, warranty terms, and the video file if you were promised one. A link that expires in two days is a poor record; ask for a copy you can keep. If something was not finished, the note should say what remains and when they return. “We’ll swing by” is not a date.

Answers that should slow you down

Pressure to sign a financing contract in the driveway before a diagnosis is a reason to pause. So is a cash price with no invoice, a refusal to describe the credential, or a story that your only option is the most expensive one they sell, told before they have looked. You do not need a villain. You need a second description of the same symptom. Another company should be able to read the first company’s notes and either agree or explain the difference.

A very low number that cannot survive the questions above is not a bargain yet. Compare scope. If you are tired and the basement is wet, you can still approve a stopgap—“make it stop tonight”—and leave the permanent repair for a written bid tomorrow. Say that out loud so tonight’s invoice does not quietly become a full replacement.

Put the answers next to the notes you already wrote

The service-notes tool on this site is a private page in your browser. Nothing is submitted to us. Use it so the questions above are not reconstructed from memory while someone is standing in the hallway. Add the answers in the margin: credential you were given, diagnostic fee, what is included, permit yes or no, warranty length.

Then decide. Hiring is a purchase of a defined repair, not a test of politeness. The companies that do good work in Indianapolis can answer these questions without treating them as an insult. If the tone collapses because you asked who pulls the permit, you have learned something before the wall was opened.
