Part 3: The 12 Questions to Ask Every Contractor
Before you sign a contract or hand over a deposit, get answers to all of these:
Licensing & Insurance
- Are you licensed to do this work in [your state/county]? Can I see your license number?
- Do you carry general liability insurance? What is the coverage amount?
- Do you carry workers' compensation insurance for your crew?
Experience & References
- How many projects like mine have you completed in the past 12 months?
- Can you provide 3 references from similar recent jobs I can call?
- Do you have photos of completed work I can review?
The Quote & Contract
- Is this quote fixed-price or time-and-materials? What could cause it to change?
- What exactly is included — and what is explicitly excluded?
- What is the payment schedule? (Never pay more than 10–30% upfront for large jobs)
Timeline & Crew
- Who will actually be doing the work — your employees or subcontractors?
- What is the realistic start date and expected completion date?
- How do you handle unexpected issues or change orders during the project?
Part 4: Red Flags — Walk Away If You See These
- Requires full payment upfront — Legitimate contractors don't need 100% before starting.
- No written contract — Verbal agreements protect no one.
- Unusually low bid — If it seems too good to be true, it is. Often signals skipped materials or unlicensed work.
- Pressures you to decide immediately — Reputable contractors don't use high-pressure tactics.
- Can't provide proof of insurance — You could be liable for injuries on your property.
- Door-to-door solicitation after a storm — A classic scam — always verify independently.
- Asks you to pull the permit — Contractors should pull their own permits. If they ask you to, they may be unlicensed.
- Cash only, no receipt — No paper trail = no recourse.
Part 5: How to Get the Best Price
- Get 3+ quotes — always, for any job over $500.
- Schedule off-season — roofing in winter, HVAC in spring/fall.
- Bundle work — combine projects to reduce mobilization costs.
- Ask about financing — many reputable contractors offer 0% or low-interest options.
- Check for rebates — utility, manufacturer, and state programs can cut 10–30% off HVAC and solar.
- Negotiate payment terms — a final holdback (10–15%) until punch-list completion keeps contractors motivated to finish strong.
