How to Avoid Bad Contractors in Illinois
A practical homeowner checklist for comparing written estimates, payment schedules, insurance, permits, references, and project communication before hiring.
The Red Flags List
These are the warning signs that should make you slow down — or walk away entirely:
- 🚩 Demands full payment before the work is complete. Require a written payment schedule tied to materials, progress, and final walkthrough.
- 🚩 No written contract or written estimate. "I'll just send you an invoice when it's done" is how people get blindsided by surprise charges.
- 🚩 Can't provide a verifiable business identity. Confirm the business name, contact information, local history, and recent references. A legitimate service-area business may keep a home address private.
- 🚩 Will not document permit responsibility. Permit and inspection rules vary by project and municipality, so confirm the responsible party in writing before work starts.
- 🚩 Pressure to sign today. "This price is only good today" is a sales tactic, not a reason to skip your due diligence.
- 🚩 Cash only. No paper trail = no protection if things go wrong.
- 🚩 A price that is dramatically lower without explanation. Compare scope, materials, allowances, exclusions, and change-order terms before deciding.
- 🚩 Won't provide proof of insurance. Not just says they're insured — actually provides a certificate you can verify with a call to their insurance company.
- 🚩 Vague scope of work. "We'll build your deck" is not a scope. A real quote specifies materials by brand/grade, dimensions, and exactly what's included.
- 🚩 Will not explain who will perform the work. Ask who supervises the project, which trades may be subcontracted, and who remains accountable for communication.
Common Contractor Scams in Metro East Illinois
The "storm chaser" / door-to-door approach
After major storms, homeowners may receive unsolicited offers from unfamiliar companies. Confirm the business identity, insurance, references, written scope, and payment schedule before authorizing work.
The Illinois Attorney General recommends getting more than one written estimate, resisting high-pressure sales tactics, confirming the business name and address, and reviewing the complete contract and payment schedule. Read the state home-repair guidance.
The low-bid bait and switch
Contractor bids low to win the job, then hits you with "unexpected" change orders once the project is underway. When the work is half done, you have no leverage — you have to pay to get it finished. Prevention: get a detailed written contract that specifies materials and scope before any work starts.
The permit dodge
Contractor skips the permit to save time and money — theirs, not yours. You end up with an unpermitted structure that causes problems when you sell, or that fails inspection and has to be torn down. Ask every contractor: "Do you pull the permit, or do I?" The answer should always be "we do."
The materials upcharge
Contractor quotes using generic "standard materials," then shows up with cheaper materials than what you discussed. Get specific: Trex Transcend vs basic composite, 4×4 vs 4×6 posts, pressure-treated #2 lumber. Brand and grade should be in the contract.
The undocumented payment schedule
A down payment, progress payments, material purchases, change orders, and final payment should be documented before work begins. Avoid full payment in advance and keep receipts for every payment.
The Deposit Question: How Much Is Reasonable?
| Payment Step | What to Confirm in Writing |
|---|---|
| Down payment | Amount, purpose, due date, and whether it covers ordered materials |
| Progress payments | Specific work milestones or delivered materials that trigger payment |
| Change orders | Written approval and price before additional work begins |
| Final payment | Completion, walkthrough, closeout items, and required documentation |
Project size and material requirements vary. The safest approach is a written schedule that explains each payment and connects progress payments to visible milestones or delivered materials.
How to Actually Verify a Contractor's Insurance
Saying "I'm insured" is not the same as being insured. Here's how to verify:
- Ask for a Certificate of Insurance (COI) — this is a standard document contractors carry. It shows the insurance company, policy number, and coverage amounts.
- Call the insurance company directly — the COI has the insurer's phone number. Call and confirm the policy is current and active for the contractor's name.
- Verify they have both liability AND workers comp — liability covers damage to your property; workers comp covers their employees if injured on your job. If a worker is injured and the contractor has no workers comp, you may be liable.
- Check coverage amounts — minimum $1,000,000 general liability for residential construction is standard.
All-Pro carries full liability insurance and workers compensation on every job. We provide a certificate of insurance to every customer before work starts — you don't have to ask.
What Your Contract Must Include
A legitimate contractor contract is not a one-page form. It should include:
- Detailed scope of work — what exactly is being built, where, and how
- Materials specified by brand and grade — not just "composite decking" but "Trex Enhance, 5/4 x 6, Gray"
- Project dimensions — exact size of the structure being built
- Total project cost — no "TBD" line items without clear triggers
- Payment schedule — amounts tied to project milestones
- Start date and estimated completion — with language about what happens if timelines slip
- Permit responsibility — who pulls the permit, who pays the permit fee
- Change order process — how changes to scope are documented and priced
- Warranty terms — what's covered, for how long, and what voids it
- Cleanup and haul-away — who removes debris and old materials
