Whether you're planning a kitchen remodel, a bathroom renovation, or a major addition, hiring the right contractor can make or break your project. A great contractor delivers quality work on time and on budget. A bad one? They can drain your bank account, leave projects half-finished, and turn your dream renovation into a nightmare.
The home improvement industry is worth over $600 billion a year, and unfortunately, it attracts its share of scammers and incompetent operators. But here's the good news: if you know what to look for — and what to avoid — you can protect yourself and find a contractor who'll do an amazing job. This guide will show you exactly how.
Where to Find Good Contractors
Let's start with where to look. Not all sources are created equal:
Best Sources
- Personal referrals from friends and neighbors: This is hands-down the best way to find a contractor. If your neighbor just had their kitchen remodeled and loves the result, that contractor is probably worth calling. Ask if you can see the finished work in person.
- Local building supply stores: The pros who shop at specialty building supply stores (not just big box retailers) tend to be serious about their craft. Ask the staff who they'd recommend.
- Trade associations: Organizations like the National Association of the Remodeling Industry (NARI) and the National Association of Home Builders (NAHB) have member directories. Members have typically committed to ethical standards and continuing education.
- Your local building department: Some municipalities maintain lists of licensed contractors, and inspectors often know who does quality work in the area.
Use With Caution
- Online platforms (Angi, HomeAdvisor, Thumbtack): These can be useful for getting initial leads, but take reviews with a grain of salt. Some contractors pay for leads and inflate their profiles. Always verify independently.
- Social media recommendations: Facebook groups and Nextdoor can surface good contractors, but there's no verification. Use these as a starting point, not as the sole basis for hiring.
Avoid
- Door-to-door solicitors: If someone shows up at your door offering a "special deal" because they're "working in the neighborhood," be very wary. Legitimate contractors rarely solicit door-to-door.
- Craigslist ads without business credentials: While some legitimate contractors advertise on Craigslist, it's also a hotbed for unlicensed and uninsured operators.
How to Vet a Contractor: The Complete Checklist
Once you have a few names, it's time to do your due diligence. Here's exactly what to check:
1. Verify Their License
Every state (and many municipalities) require contractors to be licensed. Here's how to check:
- Ask for their license number upfront — a legitimate contractor will have it ready
- Verify it on your state's licensing board website
- Confirm the license is current (not expired or suspended)
- Check that the license covers the type of work you need (general contractor vs. specialty trades)
Important: In states like California, you can search the Contractors State License Board (CSLB) database online and see license status, bond information, workers' comp insurance, and any complaints filed. Your state likely has a similar resource.
2. Confirm Insurance
This is non-negotiable. Every contractor you hire must carry:
- General liability insurance: Covers damage to your property caused by the contractor's work (minimum $1 million)
- Workers' compensation insurance: Covers injuries to the contractor's employees on your property. Without this, you could be liable if a worker gets hurt on your property.
Don't just take their word for it — ask for a Certificate of Insurance (COI) and call the insurance company to verify it's current. A reputable contractor will have no problem providing this.
3. Check References
- Ask for at least 3–5 references from recent projects similar to yours
- Actually call them (most people skip this step!)
- Ask specific questions: Was the project completed on time? On budget? Would you hire them again? How did they handle problems?
- If possible, visit a completed project in person
4. Look Up Reviews and Complaints
- Check the Better Business Bureau (BBB) for complaints
- Search Google Reviews, Yelp, and Angi
- Check your state's licensing board for disciplinary actions
- Search their business name in your local court records for lawsuits
5. Verify Their Business Is Established
- How long have they been in business? (5+ years is a good sign)
- Do they have a physical business address (not just a P.O. box)?
- Do they have a professional website with project photos?
- Are they registered with your state's Secretary of State?
Getting Quotes: The Right Way
Always get at least three written quotes for your project. Here's how to make sure you're comparing apples to apples:
What a Good Quote Should Include
- Detailed scope of work (not just "remodel kitchen" — every task spelled out)
- Materials list with specific brands and grades
- Labor costs broken out separately
- Timeline with start date and estimated completion date
- Payment schedule
- How change orders will be handled
- Warranty information
Watch out: If a quote is significantly lower than the others (20%+ less), that's a red flag, not a bargain. Either they're cutting corners on materials, planning to use unlicensed subcontractors, or they'll hit you with change orders later.
Questions to Ask Every Contractor
- Who will be on-site managing the project daily?
- Will you use subcontractors? If so, are they licensed and insured?
- How do you handle unexpected issues or changes?
- What permits will be needed, and will you pull them?
- What's your warranty on labor? On materials?
- Can I see your portfolio of completed projects?
- What's the best way to communicate during the project?
The Contract: Your Most Important Protection
Never — and I mean never — start work without a detailed written contract. A handshake deal is not a contract. Here's what every contract should include:
Essential Contract Elements
- Full legal names and addresses of both parties
- Contractor's license number and insurance information
- Detailed scope of work — every task, material, and specification
- Total project cost with itemized breakdown
- Payment schedule (see below for guidelines)
- Start and completion dates
- Change order process — how changes are priced, approved, and documented
- Permit responsibilities — who pulls and pays for permits
- Cleanup and debris removal — who's responsible
- Warranty — minimum 1 year on labor, with manufacturer warranties on materials
- Dispute resolution clause — mediation or arbitration before litigation
- Cancellation policy — your right to cancel within a reasonable period
- Lien waiver requirement — contractor must provide lien waivers with each payment
