How to Choose a Painting Contractor in Chicagoland

The best way to hire a painter you can trust is to compare quotes on scope, not just price: insurance, the paint product and number of coats, the prep included, and a written warranty. Here’s exactly what to check and what to ask.

A 7-point checklist for hiring a painter

Proof of insurance (and a license where required)
Ask for a current certificate of general liability and workers’ comp insurance. This protects you if a worker is injured or your property is damaged. In Illinois, painting doesn’t require a state license, so insurance is the key credential.
A written, itemized quote
A real quote lists surfaces, number of coats, the specific paint product, prep included, and the total price. A one-line number with no detail is a red flag — you can’t compare it or hold anyone to it.
The paint product and number of coats, in writing
Premium paint (e.g., Sherwin-Williams Cashmere/Emerald or Duration for exteriors) and two coats are the difference between a job that lasts 3 years and one that lasts 8. Get the product name and coat count on the quote.
How prep is handled
Most of a lasting result is prep: power-washing, scraping, sanding, patching, caulking, and priming bare spots. Ask what prep is included and what could cost extra once work starts.
Reviews and recent local references
Look for recent Google reviews and ask for a few nearby jobs from the last year. Local, verifiable work matters more than a star count alone.
A written warranty
Reputable painters warranty their workmanship (commonly 2 years or more). Get the term and what it covers in writing.
Clear, transparent pricing
You should understand exactly what you’re paying for before work begins. Instant, itemized pricing you can review at home — with no pressure and no surprise change orders — is the modern standard.

Red flags to avoid

Large upfront deposit (more than ~1/3) or cash-only, no contract
A vague price with no product, coats, or prep detail
No proof of insurance, or pressure to decide "today only"
No written warranty
Door-to-door "we have leftover paint from a nearby job" pitches

Questions to ask before you hire

Are you insured for general liability and workers’ comp — can I see the certificate?
What paint product will you use, and how many coats?
What prep is included, and what could cost extra?
Is there a written workmanship warranty, and for how long?
Can I see itemized pricing before I commit?

Frequently asked questions

Do painters need a license in Illinois?

Illinois does not require a state painting license, so the credentials that matter most are current general-liability and workers’ compensation insurance, plus a written contract and warranty. Some municipalities require a local business registration.

What questions should I ask a painting contractor?

Are you insured (can I see the certificate)? What paint product and how many coats? What prep is included? Is there a written warranty and how long? Can I see recent local reviews or references? Is the quote itemized and fixed?

How many quotes should I get?

Two or three is plenty. Compare them on scope — product, coats, and prep — not just the bottom-line price. The cheapest bid often means thinner paint, fewer coats, or less prep.

How can I compare painting quotes fairly?

Make sure each quote lists the same surfaces, the same number of coats, the same paint tier, and the same prep. A transparent, itemized estimate makes this easy; a single lump-sum number does not.
