10 Essential Tips for Choosing the Right Construction Contractor

Selecting the right contractor can make the difference between a dream home and a nightmare project. Learn how to vet contractors properly, identify red flags, and protect your investment.

By Building Experts

⚠️ Why This Matters

Contractor-related problems are the #1 cause of construction project failures, delays, and cost overruns. Studies show that 30-40% of homeowners experience significant issues with contractors. Taking time to properly vet and select your contractor is the single most important decision you'll make in your construction project.

Your contractor choice will impact every aspect of your construction project—from initial planning through final completion. A great contractor brings expertise, reliability, and peace of mind. A poor contractor can result in shoddy work, cost overruns, delays, and even legal problems. Here's how to make the right choice.

1. Verify Licensing and Insurance

This is non-negotiable. Every contractor you consider must have proper licensing and comprehensive insurance. Don't take their word for it—verify everything directly with the appropriate authorities.

Required Credentials Checklist

âś“ Contractor's License

  • Valid state or local contractor's license
  • Verify license number with state contractor board
  • Check for any disciplinary actions or complaints
  • Ensure license classification matches your project type
  • Confirm license is current and not expired

âś“ General Liability Insurance

  • Minimum $1 million coverage (verify with insurance company)
  • Get certificate of insurance naming you as additional insured
  • Verify policy is current and paid up
  • Confirm coverage includes property damage and bodily injury

âś“ Workers' Compensation Insurance

  • Required in most states for contractors with employees
  • Protects you from liability if worker is injured on your property
  • Request certificate showing current coverage
  • Verify coverage amounts meet state requirements

Optional but Recommended

  • Builder's risk insurance (covers property during construction)
  • Performance bond (guarantees project completion)
  • Payment bond (ensures subcontractors and suppliers are paid)

đźš« Red Flag Alert

If a contractor hesitates to provide insurance certificates or license numbers, or if they say "don't worry about it" or "we're covered through someone else," walk away immediately. This is a critical red flag indicating either lack of proper credentials or dishonesty. Working with an unlicensed or uninsured contractor puts you at enormous financial and legal risk.

2. Check References Thoroughly

Don't just ask for references—actually call them and ask specific questions. Any contractor worth hiring will have satisfied customers willing to talk about their experience.

Questions to Ask References

About Quality & Work

  • • How was the overall quality of work?
  • • Did they follow plans and specifications exactly?
  • • Were there any defects or problems after completion?
  • • How did they handle any issues that arose?
  • • Would you hire them again?
  • • Can I see the completed project?

About Process & Management

  • • Did they stay on schedule?
  • • Did they stay on budget?
  • • How was communication throughout?
  • • How did they handle changes or unexpected issues?
  • • Were their subcontractors professional and skilled?
  • • Did they clean up properly each day?

đź’ˇ Pro Tip: Visit Completed Projects

Ask to visit 2-3 completed projects, including at least one that's 1-2 years old. This allows you to see how work holds up over time and observe the contractor's craftsmanship firsthand. Pay special attention to details like trim work, tile alignment, paint quality, and overall finish.

3. Get Multiple Detailed Bids

Never accept the first bid. Get at least three detailed bids from different contractors, all based on the same plans and specifications. This helps you understand fair market pricing and compare contractor approaches.

What a Proper Bid Should Include

Detailed Line-Item Breakdown

Separate costs for materials, labor, subcontractors, permits, and overhead. Avoid lump-sum bids that don't show where money is going.

Project Timeline

Start date, major milestone dates, and estimated completion date. Include allowances for weather delays and inspection timing.

Material Specifications

Specific brands, models, and grades of materials. Avoid vague terms like "builder grade" or "standard quality."

Payment Schedule

When payments are due, tied to specific project milestones. Never pay more than 10% upfront, and never pay in full before final inspection.

Warranty Information

What's covered, for how long, and what's excluded. Typically 1 year on workmanship, longer on specific systems or materials.

⚠️ Beware of Significantly Low Bids

If one bid is 20-30% lower than others, that's a red flag. Common reasons for suspiciously low bids: (1) Contractor doesn't understand the scope and will demand changes later, (2) Planning to use inferior materials or cut corners, (3) Will start but not finish, leaving you stuck, (4) Financially unstable and desperate for work. The lowest bid is rarely the best value.

4. Assess Communication and Professionalism

How a contractor communicates during the bidding process often predicts how they'll communicate during construction. Pay attention to responsiveness, clarity, and professionalism from your first interaction.

âś“ Good Communication Signs

  • • Returns calls and emails within 24 hours
  • • Asks detailed questions about your project
  • • Explains things clearly without jargon
  • • Provides written documentation of discussions
  • • Answers questions thoroughly and patiently
  • • Proactively communicates potential issues
  • • Respects your time and scheduling

âś— Poor Communication Red Flags

  • • Takes days to return calls or never returns them
  • • Gives vague or evasive answers
  • • Pressures you to make quick decisions
  • • Dismisses your questions or concerns
  • • Only communicates verbally, avoids writing
  • • Shows up late or misses appointments
  • • Becomes defensive when questioned

5. Review Their Portfolio and Experience

Make sure the contractor has substantial experience with projects similar to yours in size, style, complexity, and budget. A contractor who mainly does small renovations may struggle with new construction, and vice versa.

Experience Questions to Ask

How many projects like mine have you completed?

Look for at least 3-5 similar projects. Ask to see photos and visit completed examples.

How long have you been in business?

Prefer contractors with 5+ years in business. New contractors aren't necessarily bad, but experience matters for handling unexpected issues.

What's your typical project size and budget range?

Your project should fit comfortably within their typical range. Too small and you won't get priority; too large and they may be over their heads.

Do you have experience with [specific feature]?

If your project includes special features (energy-efficient systems, specific architectural styles, complex site work), ensure they have specific experience.

6. Check Financial Stability

A contractor's financial health affects their ability to complete your project. Financially struggling contractors may abandon projects, fail to pay subcontractors (which can result in liens on your property), or cut corners to save money.

Financial Health Indicators

  • •Credit check: For large projects, consider asking contractor to authorize a business credit check (some lenders require this anyway)
  • •Supplier relationships: Ask for references from regular suppliers. Good relationships indicate they pay bills on time
  • •Payment terms: Be wary if contractor demands unusual payment terms like large upfront deposits or cash-only payments
  • •Current workload: Too many simultaneous projects may indicate cash flow problems or inability to focus on your project

7. Understand Their Subcontractor Network

General contractors don't do all work themselves—they coordinate subcontractors for specialized trades (electrical, plumbing, HVAC, etc.). The quality of their subcontractor network directly impacts your project quality.

Questions About Subcontractors

  • • Do you use the same subcontractors regularly, or hire new ones for each project?
  • • Are all subcontractors licensed and insured? (Get copies of certificates)
  • • Can I meet key subcontractors before signing the contract?
  • • How do you handle subcontractor problems or no-shows?
  • • What's your process for inspecting and approving subcontractor work?

Best scenario: Contractor uses established team of subcontractors they've worked with for years. This indicates good relationships, reliable quality, and smoother coordination.

8. Review the Contract Carefully

Never start work with a handshake deal or informal agreement. Get everything in writing with a detailed contract. Have a lawyer review any contract before signing, especially for projects over $100,000.

Essential Contract Elements

✓Detailed scope of work
✓Complete material specifications
✓Project timeline with milestones
✓Payment schedule tied to milestones
✓Change order procedures
✓Warranty terms and duration
✓Dispute resolution process
✓Termination clauses (for both parties)
✓Insurance requirements
✓Permit responsibilities
✓Cleanup and debris removal
✓Final inspection requirements

đźš« Never Sign If Contract Includes

  • • Vague language or "to be determined" for major elements
  • • Large upfront payment (more than 10-15%)
  • • Blanket waiver of your legal rights
  • • No specific timeline or completion date
  • • Contractor's right to unlimited change orders
  • • Mandatory arbitration with contractor-chosen arbitrator

9. Trust Your Instincts

After all the practical vetting, don't ignore your gut feeling. You'll be working closely with this contractor for months. If something feels off, if they make you uncomfortable, or if you don't feel confident in them—even if you can't pinpoint exactly why—keep looking.

Trust Your Gut If You Notice:

  • • Contractor seems evasive or avoids direct answers
  • • High-pressure sales tactics or rushing you to sign
  • • Promises that sound too good to be true
  • • Unprofessional behavior or appearance
  • • Dismissive attitude toward your questions or concerns
  • • Something just "feels wrong" even if you can't articulate it

10. Check Online Reviews and Ratings

While online reviews aren't the whole story, they provide valuable insights into a contractor's reputation and how they handle problems. Check multiple platforms for a complete picture.

Where to Check Reviews

Better Business Bureau (BBB)

Check rating, complaints, and how they responded to issues

Google Reviews

Look at overall rating and read detailed reviews, both positive and negative

Angie's List / Angi

Verified reviews from actual customers

State Contractor Licensing Board

Official complaints, disciplinary actions, license status

How to Read Reviews Effectively

  • • Look for patterns, not isolated complaints (every contractor has some unhappy customers)
  • • Pay attention to how contractor responds to negative reviews
  • • Be skeptical of all 5-star reviews (may be fake or from friends/family)
  • • Read detailed reviews that mention specifics, not just "great job!"
  • • Recent reviews are more relevant than those from 3-5 years ago

Red Flags to Never Ignore

Walk Away Immediately If You See These:

  • đźš«No license or insurance
  • đźš«Demands large cash deposits
  • đźš«No written contract or vague agreements
  • đźš«Pressure to sign immediately
  • đźš«Can't provide references
  • đźš«Reluctant to show completed work
  • đźš«Multiple complaints with licensing board
  • đźš«Won't communicate in writing
  • đźš«Claims permits aren't necessary
  • đźš«Offers to skip inspections to "save money"
