Why Hiring the Right Contractor Matters

The Cost of Getting It Wrong:

Real contractor disasters:

Case 1: The Disappearing Act

“Paid $15,000 upfront for a kitchen remodel. Contractor did 2 days of demo, then disappeared. Never answered calls. Had to hire lawyer ($3,500), then new contractor to fix his demo mistakes ($4,200). Total loss: $22,700.”

Sarah M., Portland, OR

Case 2: The Unlicensed ‘Professional’

“Hired contractor from Craigslist to add a bathroom ($18K quote). Work looked good until home inspection before sale. Unpermitted work, not to code, shower leaking into wall. Had to tear out everything and redo with licensed contractor ($28,000). Lost the sale.”

Michael T., Austin, TX

Case 3: The Low-Ball Special

“Chose lowest bid for deck ($8,500 vs $14,000 others). Used wrong lumber, improper footings, no permits. Deck failed inspection, condemned as unsafe after 8 months. Cost to rebuild correctly: $16,500.”

Jennifer L., Seattle, WA

What These Disasters Have in Common:

❌ Didn’t verify contractor license
❌ Paid large amounts upfront (>30%)
❌ Skipped permit process
❌ Choose based on price alone
❌ Didn’t check references thoroughly
❌ No written contract or vague terms

Every single one of these disasters was preventable.


Step 1: Define Your Project Before You Start

Before contacting any contractor, get crystal clear on:

A. Project Scope

Write down EXACTLY what you want done:

Bad (too vague):

“Remodel the kitchen”

Good (specific):

“Replace 18 linear feet of cabinets (stock maple, shaker style), install quartz countertops (40 sq ft), replace sink and faucet, install subway tile backsplash (15 sq ft), replace flooring with LVP (120 sq ft), update lighting with 6 recessed LEDs”

Why specificity matters:

  • Contractors can give accurate bids
  • Reduces scope creep
  • Easier to compare bids apples-to-apples
  • Protects you in contract disputes

B. Budget Range

Know your realistic budget BEFORE getting bids:

Use Kukun Cost Estimator to determine:

  • What your project should cost
  • Material vs. labor breakdown
  • Regional cost variations
  • ROI expectations

Why this matters:

  • Helps identify unrealistic (too low) bids
  • Prevents you from over-improving
  • Gives you negotiating power
  • Helps contractors recommend appropriate materials

C. Timeline Expectations

Realistic timelines for common projects:

ProjectTypical DurationWith Permits
Kitchen remodel (midrange)4-8 weeks6-12 weeks
Bathroom remodel2-4 weeks4-8 weeks
Room addition8-12 weeks12-20 weeks
Deck installation1-3 weeks3-6 weeks
Basement finishing4-8 weeks6-12 weeks
Roof replacement3-7 days2-4 weeks

Red flag: Contractor promises timeline 50%+ faster than industry standard (likely to cut corners)

D. Must-Haves vs. Nice-to-Haves

Prioritize your wish list:

Must-Haves (non-negotiable):

  • Licensed and insured
  • Permits handled
  • Written contract
  • Warranty on work
  • References available

Nice-to-Haves (negotiable):

  • Designer services
  • Faster timeline
  • Premium materials
  • Extended warranty

Step 2: Find Qualified Contractor Candidates (3-5 Minimum)

Never hire the first contractor you find. Get 3-5 bids minimum to:

  • Compare pricing
  • Assess professionalism
  • Identify outliers (too high or suspiciously low)
  • Learn about different approaches

Where to Find Contractors:

Option 1: Pre-Vetted Contractor Networks (BEST) ⭐⭐⭐⭐⭐

Kukun Contractor Finder:

  • Pre-verified licensing and insurance
  • Customer reviews and ratings

  3. “How was communication?”
  4. “Any surprises or problems?”
  5. “Would you hire them again?”

Pros:

Option 5: Local Building Supply Stores ⭐⭐⭐

Ask at Home Depot Pro Desk, Lowe’s, and local lumber yards.

Pros:

  • ✅ Active contractors (not fly-by-night)
  • ✅ Material suppliers know who pays bills

Cons:

  • ⚠️ Informal referrals (no official vetting)

Where NOT to Find Contractors:

Door-to-door solicitations (“I was working in your neighborhood…”)
Craigslist (no verification, high fraud risk)
Unmarked trucks (no business identity = red flag)
Flyers on telephone poles (unlicensed)
Facebook Marketplace (no vetting)

Exception: Established contractors MAY use these platforms, but require extra vetting.


Step 3: Verify Licenses and Insurance (NON-NEGOTIABLE)

duties of a contractor

This is where most homeowner mistakes happen. Skipping this step can cost you $10,000-$50,000.

A. Verify Contractor License

Every state requires contractors to be licensed for projects over a certain amount (typically $500-$3,000, depending on the state).

How to Verify Contractor License:

Step 1: Ask the contractor for the license number

If they hesitate or make excuses (“it’s at the office,” “it’s being renewed”), that’s a red flag.

Step 2: Verify with state licensing board

Use NASCLA (National Association of State Contractors Licensing Agencies):
NASCLA.org

Or search: “[Your state] contractor license verification”

What to check:

  • ✓ License is active (not expired, suspended, or revoked)
  • ✓ Matches contractor’s business name
  • ✓ Appropriate license class for your project
  • ✓ No disciplinary actions
  • ✓ Bond is current (if required)

State Licensing Requirements by State:

StateLicense RequiredMinimum Project $Where to Verify
CaliforniaYes$500+CSLB.ca.gov
TexasVaries by cityVariesCheck local municipality
FloridaYesAll projectsMyFloridaLicense.com
New YorkVaries by trade$200+Check local municipality
IllinoisVaries by cityVariesCheck local municipality

Important: Some states don’t have statewide licensing (like Texas), but cities/counties do. ALWAYS check your local requirements.


B. Verify Insurance (ABSOLUTELY CRITICAL)

Required insurance types:

1. General Liability Insurance

What it covers:

  • Property damage contractor causes
  • Injuries to third parties
  • Damage to your home during work

Minimum coverage: $500,000-$1,000,000

How to verify:

  • Ask contractor for Certificate of Insurance (COI)
  • Call insurance company directly to verify it’s current
  • Ensure YOU (homeowner) are listed as “additionally insured”

Red flag: Contractor says “I’ll add you to policy” but can’t provide COI immediately


2. Workers’ Compensation Insurance

What it covers:

  • Injuries to contractor’s workers on your property

Why you need it: Without workers’ comp, YOU can be liable if a worker is injured on your property. This can cost $100,000-$500,000+.

How to verify:

  • Ask for Workers’ Comp certificate
  • Verify with state workers’ comp board
  • If contractor has <3 employees, some states don’t require it (but get written waiver)

CRITICAL: Never let ANY workers on your property without verified workers’ comp coverage.


C. What Happens If You Skip License/Insurance Verification?

Real consequences:

No License:

  • Work may not pass inspection
  • No permit pulled = can’t sell house without fixing
  • No legal recourse if contractor disappears
  • Homeowner’s insurance may not cover damage
  • You pay twice (bad contractor + licensed contractor to fix)

No Insurance:

  • YOU pay if contractor damages your property
  • YOU pay if worker is injured (including long-term disability)
  • YOU pay if neighbor’s property is damaged
  • Can result in losing your home in lawsuit

Cost of skipping verification: $10,000-$500,000+


Step 4: Check References and Past Work

Verified license + insurance = contractor is legal. But are they GOOD?

How to Check References:

Ask contractor for 3-5 references from past year:

  • Similar project type
  • Similar budget range
  • Projects completed (not in progress)

Questions to Ask References:

About Quality:

  1. “How would you rate the quality of work on a scale of 1-10?”
  2. “Were there any issues with workmanship?”
  3. “Did anything need to be redone or fixed?”

About Professionalism: 4. “Did they show up on time consistently?” 5. “How was communication? Responsive?” 6. “Were they clean and respectful of your home?”

About Budget & Timeline: 7. “Did they stay on budget? Any surprise costs?” 8. “Did they finish on time?” 9. “How did they handle change orders?”

About Problems: 10. “Were there any problems? How were they resolved?” 11. “Did they clean up after themselves daily?” 12. “Anything you wish you’d known before hiring them?”

The Big One: 13. “Would you hire them again?” (This is the most telling question)


Red Flags When Checking References:

🚩 Contractor can’t provide references (“clients want privacy”)
🚩 All references are from 3+ years ago (what happened recently?)
🚩 References seem scripted (possibly family/friends)
🚩 Multiple references report same issues (pattern of behavior)
🚩 Can’t visit completed projects (“clients don’t want visitors”)


Check Online Reviews:

Where to look:

  • Google Business Reviews
  • Better Business Bureau (BBB.org)
  • State licensing board (disciplinary actions)
  • Yelp (use with caution, can be manipulated)
  • Houzz (for design/build)

What to look for:

  • ✓ Overall rating 4.0+ stars
  • ✓ Minimum 10-20 reviews
  • ✓ Recent reviews (within past year)
  • ✓ How contractor responds to negative reviews
  • ✓ Patterns in feedback (good or bad)

Red flags:

  • 🚩 All 5-star reviews (suspicious)
  • 🚩 All reviews same date (likely fake)
  • 🚩 Generic reviews (“great work, highly recommend”)
  • 🚩 Contractor argues with negative reviewers
  • 🚩 Multiple reviews about same issue

Visit Past Project Sites (If Possible):

Why this matters:

  • Photos can be misleading
  • Quality becomes apparent in person
  • Talk to homeowner without contractor present
  • See long-term durability (not just fresh install)

What to look for:

  • Attention to detail (trim, edges, finish quality)
  • Straight lines and level surfaces
  • Clean caulking/grout lines
  • Doors/drawers function smoothly
  • Professional-looking results

Step 5: Get Detailed Written Bids (3-5 Minimum)

Never accept verbal quotes. Always get detailed, written bids.

What a Good Bid Should Include:

1. Detailed Scope of Work

Bad (vague):

“Remodel bathroom – $12,000”

Good (specific):

“Remove existing fixtures and tile. Install 60″x32″ acrylic tub/shower unit (Brand X Model Y). Install 36″ vanity with quartz countertop. Install comfort-height toilet (Brand X Model Y). Install ceramic tile flooring (Brand X, 100 sq ft). Paint walls (2 coats, Benjamin Moore paint). Install chrome faucet and fixtures (Brand X). Install exhaust fan (110 CFM, Brand X).”


2. Materials Specified

Must include:

  • Brand names
  • Model numbers
  • Quantities
  • Grade/quality level
  • Who provides materials (contractor or homeowner)

Why this matters: “Granite countertops” could mean $2,000 or $8,000 depending on quality. Specifics prevent bait-and-switch.


3. Labor Costs

Should specify:

  • Labor hours or daily rate
  • Number of workers
  • Estimated completion time
  • Overtime policies (if applicable)

4. Payment Schedule

Typical payment schedule:

  • 10-30% upfront (deposit to secure date, order materials)
  • 25-35% at 25-50% completion (framing done, rough-ins complete)
  • 25-35% at 75% completion (major work done)
  • 10-20% upon final completion (after your inspection, before final walkthrough)

Red flags:

  • 🚩 50%+ upfront (huge red flag)
  • 🚩 Payment for materials before they arrive
  • 🚩 Final payment before work is complete
  • 🚩 All cash payments required

5. Timeline

Must include:

  • Start date
  • Estimated completion date
  • Major milestones
  • Penalty clause for delays (optional but recommended)

6. Permits and Inspections

Should specify:

  • Who obtains permits (should be contractor)
  • Permit costs (included or separate)
  • Inspection schedule
  • Who handles failed inspections

7. Warranties

Standard warranties:

  • Labor warranty: Minimum 1 year
  • Materials warranty: Varies by manufacturer (2-25 years)
  • Structural warranty: 5-10 years (for additions, major work)

Get in writing:

  • What’s covered
  • How long
  • Who to contact for warranty work

8. Change Order Process

Must specify:

  • How changes are documented
  • How pricing changes are calculated
  • Approval process
  • Timeline impact

Why this matters: Prevents “while we’re at it” costs from spiraling.


9. Cleanup and Disposal

Should include:

  • Daily cleanup expectations
  • Final cleanup
  • Debris removal and disposal
  • Dumpster costs (if needed)

10. Insurance and Licensing Information

Should be attached:

  • Copy of contractor license
  • Certificate of Liability Insurance
  • Workers’ Compensation certificate

Comparing Bids:

Create a bid comparison spreadsheet:

Insured?✓ Yes✓ Yes? Unknown

Analysis:

  • Contractor A: Best balance of price, quality, reviews
  • Contractor B: Fastest but higher cost, fewer reviews
  • Contractor C: Lowest price but NOT LICENSED (eliminate immediately)

Red Flags in Bids:

🚩 Significantly lower than others (30%+ below average)
🚩 Vague scope of work (“all materials included”)
🚩 No materials specified (opens door to cheap substitutions)
🚩 Verbal quote only (nothing in writing)
🚩 Pressure to sign immediately (“price expires today”)
🚩 No permits mentioned (planning to skip permits)
🚩 Payment schedule front-loaded (50%+ upfront)
🚩 No warranty offered (won’t stand behind work)


Step 6: Review and Negotiate the Contract

Never start work without a written, signed contract. Verbal agreements are unenforceable and leave you vulnerable.

What Should Be in the Contract:

Every contract must include:

Both parties’ information:

  • Contractor’s business name, address, phone, license number
  • Your name, address, phone
  • Property address (if different)

Detailed scope of work:

  • Everything from the bid
  • Specific materials with brands/models
  • What’s included AND excluded

Total cost and payment schedule:

  • Total project cost
  • Payment amounts and dates
  • What triggers each payment

Timeline:

  • Start date
  • Completion date
  • Consequences for delays

Change order process:

  • How changes are requested
  • How costs are adjusted
  • Written approval required

Warranty information:

  • Labor warranty terms
  • Materials warranty
  • Who handles warranty claims

Permits and inspections:

  • Who obtains permits
  • Cost of permits
  • Responsibility for inspections

Insurance and liability:

  • Contractor maintains insurance throughout project
  • Who’s responsible for damage

Cleanup:

  • Daily cleanup expectations
  • Final cleanup
  • Disposal of materials

Dispute resolution:

  • How disputes will be handled
  • Mediation/arbitration clauses

Termination clause:

  • How either party can terminate
  • Financial implications

Signatures and dates:

  • Both parties sign and date
  • Keep copies for both parties

Contract Red Flags:

🚩 No written contract offered (“we can just do a handshake”)
🚩 Vague language (“approximately,” “similar,” “equivalent”)
🚩 No specific materials (“granite countertops” without brand/color)
🚩 Final payment BEFORE completion
🚩 No cancellation clause
🚩 Waives contractor’s liability
🚩 Requires binding arbitration (limits your legal options)
🚩 Mechanic’s lien waiver required before work starts


Negotiating Tips:

What you can negotiate:

  • ✓ Payment schedule (never >30% upfront)
  • ✓ Timeline (add buffer for delays)
  • ✓ Materials (upgrade/downgrade to adjust price)
  • ✓ Warranty length
  • ✓ Scope (remove items to reduce cost)

What you shouldn’t negotiate:

  • ✗ Permits (never skip permits)
  • ✗ Insurance requirements
  • ✗ License verification
  • ✗ Quality of materials (below contractor’s recommendation)

Sample negotiation:

“Your bid is $22,000 but we budgeted $20,000. Can we use stock cabinets instead of semi-custom to get closer to our budget? Or extend the timeline by 2 weeks if that helps with scheduling?”


Step 7: Establish Communication and Payment Schedules

Before work starts, set clear expectations:

Communication:

Establish:

  • Primary point of contact (foreman, project manager, owner?)
  • Best way to reach them (text, phone, email?)
  • Response time expectations (same day, 24 hours?)
  • Daily check-in time
  • How to handle emergencies

Schedule regular check-ins:

  • Daily: Quick 5-10 minute updates
  • Weekly: Detailed progress review
  • As-needed: When decisions are required

Payment:

Best practices:

  • Never pay cash (always check with contractor’s business name)
  • Document every payment (photo of check, bank transfer record)
  • Get signed receipt for each payment
  • Never pay for work not yet completed
  • Withhold 10-20% until FINAL completion (after your inspection)

Red flags:

  • Contractor asks for cash (“to save on taxes”)
  • Wants payment to personal account (not business)
  • Pressures for early payment
  • Won’t provide receipts

During Construction:

Your responsibilities:

  • Be available for questions/decisions
  • Review work regularly
  • Document progress with photos
  • Communicate concerns immediately
  • Make payments on schedule

Contractor’s responsibilities:

  • Show up on schedule
  • Communicate delays immediately
  • Keep worksite clean
  • Respect your home
  • Follow contract specifications

Common Contractor Scams to Avoid

Scam #1: The Advance Fee Scam

How it works: Contractor demands 50-75% upfront for “materials,” then disappears.

How to avoid:

  • Never pay more than 30% upfront
  • Verify materials delivered before paying
  • Use credit card for deposit (dispute protection)

Scam #2: The Low-Ball Bid

How it works: Contractor bids significantly lower to get job, then adds constant “unexpected” costs.

How to avoid:

  • Get 3-5 bids (identify outliers)
  • Require written change order process
  • Budget 10-15% contingency

Scam #3: The Unlicensed “Professional”

How it works: Person claims to be licensed but isn’t. Does poor work, no recourse for you.

How to avoid:

  • ALWAYS verify license with state board
  • Check license matches business name
  • Verify insurance independently

Scam #4: The Bait-and-Switch

How it works: Contractor quotes premium materials, then substitutes cheap alternatives.

How to avoid:

  • Specify exact brands/models in contract
  • Inspect materials before installation
  • Take photos of material labels

Scam #5: The Permit Skipper

How it works: Contractor avoids permits to save time/money. Work fails inspection when you sell.

How to avoid:

  • Require permits in contract
  • Verify permits pulled (call city/county)
  • Never let work start without permits

Scam #6: The Lien Threat

How it works: Contractor doesn’t pay subcontractors/suppliers, they file lien on YOUR property.

How to avoid:

  • Require lien waivers from all subs before final payment
  • Verify contractor paying bills (ask for receipts)
