Hiring a Contractor: 7 Red Flags That Should End the Conversation

How to Avoid the Contractor Horror Story

Most contractor disasters share the same warning signs at the very first meeting. Here are seven that should end the conversation, no matter how charming the contractor or how good the price.

1. No Verifiable License

In California, every contractor running residential work over $500 must hold a valid Contractor's State License Board (CSLB) license. Period.

Verify it yourself: cslb.ca.gov, search by name or license number. Look for:

  • Active status
  • Bond filed
  • Workers' comp coverage if they have employees
  • License classification matching the work (B for general, B-2 for residential remodel, etc.)

Anyone unwilling to give you their license number on the first call is hiding something.

2. Cash-Only or "Off the Books" Pricing

A "discount for cash" almost always means:

  • They're not paying employees properly
  • They're not paying their workers' comp insurance
  • They have no intention of pulling permits
  • You'll have no recourse when things go wrong

The savings vanish the first time something breaks.

3. They Recommend Skipping Permits

"We'll just do this without permits, save you a few weeks." This sentence has caused more financial pain than any other in residential construction. If you ever try to refinance, sell, or insure your home, unpermitted work is a problem.

A licensed contractor who suggests skipping required permits is telling you they don't care about your long-term interest.

4. Pressure to Sign Today

Real contractors don't pressure. They give you a proposal, answer your questions, and let you compare. If the proposal "is only good for 48 hours" or you're being pushed to sign on the first visit, it's a sales tactic — and it's a tell.

5. Large Down Payment Demand

California law caps the down payment on residential work at 10% of the contract price or $1,000, whichever is less. Anyone asking for 30%, 50%, or "just the materials cost up front" is operating outside the law and putting your money at risk.

Standard payment schedule: small mobilization payment, then progress payments tied to defined milestones, with a final payment held until punch-list completion.

6. No Written Contract or a One-Page "Contract"

A real construction contract has:

  • Detailed scope of work
  • Specifications and selections
  • Payment schedule tied to milestones
  • Start and substantial completion dates
  • Change order procedure
  • Warranty terms
  • Lien waiver process
  • License and insurance details

A handshake or a one-page proposal is not a contract.

7. No References Or References You Can't Reach

A contractor with five years in business should have dozens of references. They should be willing to provide names, addresses, and phone numbers of recent jobs. They should not flinch when you ask to drive past a current job site.

If references are vague ("we did a kitchen in Glendale last year"), or you can't reach them, walk away.

Bonus Red Flags

  • Sub-bids significantly lower than competitors (the lowest bid almost always becomes the highest final cost)
  • Different person at the meeting than will run the job
  • Vague answers about who their structural engineer is
  • Refusal to put exact specifications in writing
  • "We'll figure it out as we go" attitude

What a Good Contractor Conversation Looks Like

  • Specific questions about your goals and constraints
  • Willingness to walk you through their process
  • Clear answers about license, insurance, and bonding
  • A timeline for delivering a written proposal (typically 1–3 weeks)
  • Physical proof of past work (project portfolio, addresses, references)
  • A real conversation about budget before spending design hours

What to Verify Before Signing Anything

  1. CSLB license active and matches the contractor entity name
  2. Workers' comp policy verified directly with the carrier
  3. General liability insurance certificate naming you as additional insured
  4. Bond on file with CSLB
  5. References from at least three completed projects in the last 18 months
  6. At least one job site visit (current or recent)
