What to ask before you hire

  • Get it in writing: ask whether the quote is flat-rate or hourly, and get the price and scope in writing before work starts. Reputable shops like Matthews will give you choices and prices upfront.
  • Ask about the visit fee: many plumbers charge a diagnostic or trip fee — ask whether it's waived if you approve the repair.
  • Emergency vs. scheduled: after-hours, weekend, and holiday calls generally cost more. If it's not urgent (a slow drip, a running toilet), booking a weekday slot saves money. For true emergencies — burst pipes, sewage backup — call now and confirm emergency response is offered before they roll.
  • Warranty: ask what labor and parts are covered, and for how long.
  • Permits for big work: repipes, sewer line replacements, and water heater swaps may need a village permit and inspection. Ask who pulls the permit — the contractor should.

Licensing in Illinois

Plumbers in Illinois must be licensed by the state under the Illinois Plumbing License Law, administered by the Illinois Department of Public Health. Before hiring, ask the plumber for their license number and proof of insurance — a legitimate company will provide both without hesitation. You can verify a licensee through the state's license lookup.

Plumber FAQ

How much does a plumber cost in Naperville, IL?

Pricing varies by job, time of day, and company, so get written quotes from two or three local plumbers before scheduling. Emergency and after-hours calls generally cost more than weekday scheduled work. Ask whether the quote is flat-rate or hourly, and whether the visit fee is waived if you proceed with the repair.

What counts as a plumbing emergency?

Burst or leaking pipes with active water damage, a sewage backup into the home, a leaking water heater tank, and a gas-line leak (evacuate and call the gas utility first) count as emergencies. Several Naperville-area plumbers offer 24/7 emergency response — confirm it with the company before you call.

What should I do about a burst pipe before the plumber arrives?

Shut off the water at the main valve (most Naperville homes have it near the water meter or where the line enters the house), then open faucets to drain the system. If water is near outlets or the electrical panel, stay clear and call for help if there is an active hazard. Move valuables out of the way and take photos for your insurance claim.

How do I verify an Illinois plumber's license?

Plumbers in Illinois must be licensed by the state under the Illinois Plumbing License Law. You can look up a licensee through the Illinois Department of Public Health's license lookup, and you can ask the plumber for their license number and proof of insurance before work begins.

Do Naperville-area plumbers handle sump pumps and sewer backups?

Yes — most plumbers serving Naperville list sump and sewage pumps, sewer and drain cleaning, hydro-jetting, and camera inspections among their services. Many western-suburb homes have clay sewer laterals prone to root intrusion, so ask whether a camera inspection is included if backups keep recurring.
