Hiring a contractor is one of the biggest decisions a homeowner can make. Whether you’re replacing a roof, remodeling a kitchen, or dealing with a plumbing emergency, the person you hire will have direct access to your home, your money, and your trust.
The problem? Not every contractor deserves that trust.
The good news is that a few direct questions asked upfront can reveal everything you need to know before you commit. Here are the 10 questions every homeowner should ask before hiring any contractor — and what the right answers look like.
1. Are You Licensed and Insured?
This is the first question, full stop. A legitimate contractor should carry both a valid state or local license and general liability insurance. Some trades also require workers’ compensation insurance if they have employees.
Ask for proof of both — not just a verbal confirmation. A reputable contractor will hand it over without hesitation. If they hesitate, deflect, or tell you it’s “in the works,” that’s your cue to move on.
What to look for: A license number you can verify through your state’s contractor licensing board website, and a certificate of insurance naming you as the certificate holder.
2. Do You Pull Permits for This Type of Work?
Many homeowners don’t realize that certain projects — electrical work, structural changes, HVAC replacements, additions — legally require permits. A contractor who offers to skip permits to “save you money” is actually putting you at serious risk.
Unpermitted work can cause problems when you sell your home, void your homeowner’s insurance, and leave you legally liable if something goes wrong.
What to look for: A contractor who pulls permits as a standard part of their process, not as an upsell.
3. Can You Provide References From Similar Projects?
Anyone can claim experience. References prove it. Ask for at least three references from projects similar to yours — same type of work, similar scope and budget.
Then actually call them. Ask how the project went, whether it came in on time and on budget, how the contractor handled problems, and whether they would hire them again.
What to look for: References who speak specifically and positively about the work, not just vague praise.
4. Who Will Actually Be Doing the Work?
Many contractors win the bid and then subcontract the work to crews you’ve never met and had no opportunity to vet. This isn’t always a red flag — subcontracting is common — but you deserve to know who will be in your home.
Ask whether the crew are employees or subcontractors, and whether subcontractors are also licensed and insured.
What to look for: Transparency about who will be on-site and confirmation that all workers are covered under proper insurance.
5. What Does Your Estimate Include — and Exclude?
A suspiciously low bid is often just that — suspiciously low. Some contractors win jobs by leaving items out of the estimate, then charging for them later as “extras.”
Before signing anything, ask for an itemized estimate. Review it line by line and ask specifically what is not included. Common items that get left out include debris removal, permits, materials upgrades, and site preparation.
What to look for: A detailed written estimate, not a ballpark number scribbled on a business card.
6. What Is Your Payment Schedule?
Legitimate contractors do not ask for full payment upfront. A typical payment structure might look like 10–30% at signing, additional draws tied to project milestones, and a final payment upon completion.
Be very cautious of any contractor who demands more than a third of the total cost before work begins. It’s a common setup for a contractor who takes the money and disappears — or drags the job out with no financial incentive to finish.
What to look for: A milestone-based payment schedule tied to completed work, outlined in writing.
7. Do You Offer a Written Contract?
If a contractor doesn’t use a written contract, walk away. A proper contract should include the scope of work, materials to be used, project timeline, payment schedule, change order procedures, and warranty information.
Verbal agreements are nearly impossible to enforce and leave you with no protection if something goes wrong.
What to look for: A clear, detailed contract that both parties sign before any work begins.
8. How Do You Handle Changes or Unexpected Issues?
In home improvement, surprises happen. Old wiring gets discovered behind the walls. The subfloor is rotted. The wrong materials arrive. How a contractor handles these moments defines the experience.
Ask upfront how they communicate changes, how they price change orders, and what your approval rights are before additional costs are incurred.
What to look for: A clear change order process in writing, and a contractor who won’t proceed on changes without your approval.
9. What Is Your Estimated Timeline?
Get a start date and an estimated completion date in writing. Ask what factors could cause delays and how they communicate if the schedule shifts.
A contractor who can’t give you a timeline estimate — or who is vague about when they can even start — may be overextended or disorganized.
What to look for: Realistic, specific dates with an acknowledgment of what could cause delays and a communication plan if they occur.
10. Do You Offer a Warranty on Your Work?
Good contractors stand behind their work. Ask whether they offer a workmanship warranty — separate from any manufacturer warranty on materials — and get the terms in writing.
A one-year warranty on labor is common for many trades. Some contractors offer longer. A contractor who offers no warranty should raise a red flag.
What to look for: A written workmanship warranty with clearly defined terms and a process for addressing issues after the job is complete.
The Bottom Line
Hiring a contractor doesn’t have to feel like a gamble. These 10 questions give you a simple framework to separate the professionals from the problems — before the first nail is driven or the first check is written.
A trustworthy contractor will welcome these questions. They know that a homeowner who asks good questions is also a homeowner who will respect the process, pay on time, and leave a good review when the job is done right.
Take your time, do your homework, and never feel pressured to sign on the spot.
