How to Properly Vet a Contractor Before the First Shovel Goes In
Most homeowners go into renovation consultations and let the contractor run the conversation. The contractor shows samples, describes their process, and names a price. The homeowner nods, asks about timeline, and eventually signs. By the time problems appear — missed milestones, cost overruns, or a contractor who simply stops showing up — the leverage is gone.
Knowing how to properly vet a contractor before you sign anything is the single most important step in protecting your renovation investment. It costs nothing. It takes less than an hour. And it separates professionals from risks.
Licensing & Insurance Questions
Licensing and insurance are your baseline. Any contractor unable to answer clearly here should be removed from consideration — regardless of how competitive their bid is.
Can I have your contractor license number so I can verify it on the state website?
A licensed contractor will say yes without hesitation. Most state licensing boards have a free public lookup where you can confirm the license is active, the name matches, and there are no disciplinary actions on file. This takes two minutes and filters out a significant percentage of fraudulent operators.
Can you provide a certificate of insurance I can verify directly with your insurer?
Don’t accept a copy — ask for a certificate you can call to confirm is currently active. General liability protects your property if something goes wrong. Without it, damage during the project can become your financial problem.
Do you carry workers’ compensation for your crew?
The question most homeowners skip — and one of the most consequential. If a worker is injured on your property without workers’ comp coverage, you may be liable for their medical costs and lost wages. Confirm this coverage exists before any work begins.
Contract & Payment Questions
How a contractor handles money and paperwork tells you almost everything about how they’ll handle your project. Properly vetting a contractor means understanding their payment process before you write a single check.
Can you walk me through your milestone payment schedule?
A reputable contractor ties payments to completed project phases — not to dates or verbal assurances. If they don’t have a milestone payment schedule, ask them to create one before you sign. If they resist, that’s a significant warning sign.
What is your change order process?
Every legitimate contractor should require written approval from both parties before any additional work begins. Look for: change orders in writing, signed by both parties, with revised cost and timeline documented before work proceeds. Vagueness here almost always leads to budget overruns.
Are you open to using a construction escrow company to hold and disburse project funds?
This single question reveals more about a contractor’s professionalism than almost anything else. A confident yes signals accountability. Resistance or hostility is a signal worth taking very seriously.
The Escrow Question Is Your Most Powerful Screening Tool
Construction escrow holds your project funds with a neutral third party and releases payments only when milestones are completed. When you use Build Safe Escrow, funds are never in the contractor’s hands until work is confirmed complete. This protects you from overpayment, project abandonment, and the leverage loss that comes from paying too far ahead. A contractor who welcomes this structure is telling you something important about who they are.
Project & Operations Questions
Licensing and contracts establish baseline professionalism. These four questions reveal experience, judgment, and operational accountability.
What are the three things most likely to affect the timeline or budget on a project like this?
An experienced contractor answers immediately with specific examples: permit delays, subcontractor scheduling, material lead times, hidden structural issues. Vague or dismissive answers signal inexperience or poor planning practices.
Who will be on-site daily — you, a foreman, or subcontractors? Can I meet them?
Accountability lives with the person physically on your property. Ask to meet the individual who will run your job daily. High subcontractor turnover or no consistent on-site leadership is a meaningful red flag.
What permits does this project require, and who pulls them?
Always the contractor. Never let a homeowner pull their own permits at a contractor’s request — this is a known tactic that shifts liability to you and may void your homeowner’s insurance. A legitimate contractor knows exactly which permits apply.
Can I contact three of your clients from projects completed in the last 12 months?
Not a written list — actual names and numbers you will call. Ask specifically about the last 12 months for current information. Ask each reference: Did the final cost match the estimate? Would you hire them again?

Red Flags vs. Green Flags
You’re not looking for perfect answers — you’re looking for confidence, transparency, and process. Here’s how to read what you hear:
What to Do After You Hire
Vetting a contractor is step one. Protecting yourself through the project is step two.
- 1Get everything in writing. Scope, timeline, materials, payment schedule, and change order process — all documented before day one.
- 2Never pay more than 10–15% upfront. A deposit is standard; a large upfront payment removes your leverage entirely.
- 3Use construction escrow for fund disbursement. Milestone payments held in escrow are released only when each milestone is completed.
- 4Document the project with date-stamped photos at every phase. This record is invaluable if any disputes arise.
- 5Hold final payment until the punch list is complete. The last 10–15% is your strongest remaining leverage — don’t release it early.
- 6Stay accessible and communicative. A good contractor wants you informed. Avoidance mid-project is a problem worth addressing immediately.
How Construction Escrow Protects You
Construction escrow is the structural backstop that makes everything else in this guide enforceable. Here’s how it works in practice:
Your project funds go into escrow — not directly to the contractor. This eliminates the overpayment risk that causes the worst renovation disasters.
When a phase is complete, you verify it and authorize disbursement. The contractor is financially motivated to finish each phase correctly before moving to the next.
Every disbursement authorization is on record. If a disagreement arises, the escrow history is far more useful than any verbal account.

Frequently Asked Questions
FAQLicensing and insurance form the non-negotiable baseline — no exceptions. But the single most revealing question is whether the contractor is open to using a construction escrow company to hold and disburse project funds. A professional who is confident in their ability to complete work will welcome the accountability escrow provides. Resistance to this question is one of the clearest signals that a contractor may not be the right fit for your project.
Every U.S. state maintains a public contractor license lookup database, typically through the state’s Department of Business and Professional Regulation or equivalent agency. Search “[your state] contractor license lookup” to find the official portal. Confirm: the license is currently active, the name on the license matches the person or company you’re hiring, there are no disciplinary actions or suspensions on file, and the license covers the type of work being performed. This entire process takes about two minutes.
Construction escrow is a financial arrangement where your project funds are held by a neutral third-party escrow company — rather than paid directly to the contractor upfront. Funds are only released to the contractor when specific, pre-agreed milestones are completed. This structure protects you from several of the most common renovation disasters: overpaying before work is done, contractors who abandon projects after receiving payment, and disputes about whether work was completed to standard.
A standard upfront deposit for a residential renovation is typically 10–15% of the total contract value, used to cover material purchases before work begins. Some states cap contractor deposits by law — California, for example, limits initial deposits to $1,000 or 10%, whichever is less. Any contractor requesting 30%, 40%, or 50% upfront is well outside industry norms and that request warrants serious scrutiny. The best protection is a milestone-based payment schedule from the start, where each payment is tied to completed phases of work. Construction escrow formalizes this structure and removes the risk of overpaying regardless of what a contractor requests.
Do not agree to this under any circumstances. A licensed contractor is legally required to pull their own permits in virtually every U.S. jurisdiction. When a contractor asks you to pull permits in your own name, it typically signals one or more serious problems: the contractor may not be properly licensed, they may have outstanding violations that prevent them from pulling permits, or they may be attempting to shift liability for code compliance and inspection failures onto you. If you hear this request, treat it as an automatic disqualifier and move to the next contractor on your list.
