How to Hire a Chimney Sweep in Illinois

Hiring a chimney sweep is a little different from hiring most trades, because no state license tells you the person is qualified. What you have instead is a consumer protection law, a national credential you can ask about, and your own questions. This guide covers all three. We make no claim here about any individual or company; it is a checklist for whoever you call, including us. The inspection types are on our chimney inspection page.

What Illinois does and does not require

The Illinois Attorney General says general contractors are not required to be licensed. We found no state chimney sweep or chimney contractor license listed. Roofers are state licensed through the Illinois Department of Financial and Professional Regulation, which matters when a job includes flashing or roof work (see why a chimney leaks). A city or village may still require a permit or registration. Rockford, for example, says general contractors are not required to be licensed, and Roscoe's village code says general contractors and construction managers register with the village. The page for your town under service area lists what we found.

The Home Repair and Remodeling Act protects you

This is the useful rule. The Act covers homes of one to six units, and its definition of home repair names chimneys and chimney liners:

That brings three protections.

A written contract over $1,000.

The consumer rights pamphlet. On any contract over $1,000, the contractor must give you “Home Repair: Know Your Consumer Rights” before you sign.

Insurance. The Attorney General says the Act requires contractors to carry public liability and property damage insurance. We did not retrieve the statute section itself, so we cite the Attorney General. Ask for a certificate of insurance and check that it is current.

A sweep alone is usually well under $1,000, since Angi lists $129 to $381 (national, July 10, 2026). A liner, a rebuild or a stove install usually is not: see the cost page for the ranges.

The CSIA credential

The Chimney Safety Institute of America (CSIA) is the national body behind the three inspection levels used across the industry (CSIA inspection levels). It also runs a credential for sweeps. A person can say they hold it, and you can ask to see proof and a current date. We make no claim that anyone, including us, holds it; the point is that it is something you can ask about. A credential does not replace insurance or a written quote. It tells you the person studied the work.

Questions to ask before the visit

• Which inspection level will you do, and what does the price include? (See the levels: Level 1 is a minimum when nothing is changing, Level 2 adds a camera scan of the flue.)
• Do you carry liability insurance, and can I see the certificate?
• Do you hold a CSIA credential, and can I see it?
• Will I get a written report with photos or video?
• Who is doing the roof work, if any?
• Will you pull the permit where one is needed? Rockford's number is (779) 348-7158; other towns are on their service area pages.
• If you find birds, what do you do? Chimney swifts are federally protected, so a technician who offers to “just clear them out” in summer is describing something that may be illegal. See chimney swifts in your chimney.

Ask for the camera video on a Level 2

A Level 2 inspection includes a video scan of the flue. Ask for the video, or at least stills, and watch them. This is the best protection against a bad recommendation. If a technician says a liner is cracked or the flue is damaged, you should be able to see it. Angi lists $260 to $460 for a Level 2 in its sweep guide (national, July 10, 2026) and $200 to $1,000 in its inspection guide (October 19, 2026). The two Angi pages disagree, so ask for a written price for your chimney.

Red flags

• Cash only, no paperwork. A job under $1,000 may not need a contract by law, but you still need a written receipt, and a job over $1,000 requires a contract.
• No written contract over $1,000. The Act requires it. Do not start the work without it.
• A scary claim with no camera footage. “Your chimney is going to catch fire” is a serious claim. Ask to see the damage. A real defect shows on video.
• Pressure to decide today. A cracked flue is a reason to stop using the fireplace, not a reason to sign on the spot.
• A big upfront deposit. The Attorney General's guide to choosing a contractor is the place to read what is normal.
• Vague quotes. The contract has to list parts and materials with reasonable particularity.
• No insurance. If someone falls off your roof or drops a brick, you want their policy, not yours.
• Sweeping in swift season without a plan. Sweep from October to March.

Comparing quotes

Get at least two written quotes on any job over a few hundred dollars. Compare what is in them, not the totals. One quote might include the camera scan and a written report while another is a verbal number for a sweep. Check that each lists the same work, the same materials and the same permit handling. Prices published by cost guides are national and do not include a Rockford figure, so use them as a sanity check only; the cost page lists each range with its date. A quote far below the rest should come with an explanation. A quote far above it should come with photos.

What you get when it goes well

A good visit ends with a written report that says what was done, what was found, the photos or video, and what needs attention now and what can wait. The national guidance is a yearly inspection: NFPA 211, the U.S. Fire Administration and the Consumer Product Safety Commission all say so. See how often to sweep and sweep versus inspection.
