8 Red Flags to Identify Before Signing Anything
No written contract or estimate
CriticalAny contractor who refuses to put the scope, timeline, and price in writing is protecting themselves — not you. Verbal agreements give you no recourse if the job goes wrong or the price inflates.
Demands full payment before starting
CriticalLegitimate contractors typically ask for 10–30% upfront to cover materials. Any contractor demanding 50%+ before lifting a tool is a serious risk. Full upfront payment before work begins is almost always a scam.
Cannot provide proof of license or insurance
CriticalMost states require contractors to be licensed. Ask for their license number and verify it on your state's licensing board website. If they hesitate, say they are between licenses, or become evasive, walk away.
Unusually low bid compared to competitors
High riskA quote that is 40–50% lower than everyone else is not a deal — it is a warning. Contractors who underbid often cut corners, use substandard materials, or add charges mid-project to bring the price back up.
High-pressure tactics to decide immediately
High risk"This price is only good today." "I have a crew available right now but they are booked tomorrow." These are manipulation tactics, not genuine business constraints. Reputable contractors give you time to decide.
No physical address or local presence
High riskFly-by-night contractors show up after storms, collect payment, do substandard work, and disappear before problems surface. Verify the business has a real local address — a P.O. box or virtual mailbox is a red flag.
Sudden burst of 5-star reviews
Watch for thisA business with 3 reviews last month and 47 this month has likely bought reviews. Authentic review patterns are steady and gradual. Check the dates of their Google reviews carefully.
Asks you to pull your own permits
Watch for thisFor permitted work, the licensed contractor should pull the permits in their name — not yours. If a contractor asks you to pull permits, it often means they are not licensed to do the work or want to avoid inspection.
What a Legitimate Contractor Looks Like
The good news: reputable contractors are easy to identify once you know what to look for. These characteristics appear consistently among top-ranked local contractors.
- Provides a line-item written estimate before any work begins
- Can show license and insurance certificate within 24 hours of asking
- Has a consistent history of Google reviews over 12+ months
- Responds calmly and professionally to negative reviews
- Has a physical local address and a real business phone number
- Explains the scope of work clearly and answers questions patiently
- Does not pressure you to sign or commit on the first call
Why Google Reviews Are the Most Reliable Signal
Google reviews are harder to fake at scale than any other signal. A contractor with 150+ reviews and a 4.7 rating over 3 years has been vetted by real customers repeatedly. This is why GrowLocalHub ranks contractors by review volume and consistency — not by paid placement.
Frequently Asked Questions
What are red flags when hiring a contractor?
Key red flags include demanding full payment upfront, refusing to provide a written contract, lacking a local physical address, no license or insurance, pressure tactics to decide immediately, and an unusually low quote compared to competitors.
How do I verify a contractor is legitimate?
Check their license on your state's contractor board website, request proof of insurance, verify their physical address, search their business name on Google Maps, and look for consistent reviews over time rather than a sudden burst.
Should I always get multiple quotes from contractors?
Yes. For any job over $300, get at least two written quotes. The middle quote is often the most realistic. A quote that is dramatically lower than all others is almost always a red flag.
