The Complete Washington Homeowner's Guide to Hiring a Contractor
The Complete Washington Homeowner's Guide to Hiring a Contractor
Your step-by-step checklist for finding, vetting, and working with contractors in Washington State
Before You Start: Know Your Project
Before contacting any contractor, answer these questions:
- What exactly needs to be done?
- What's your realistic budget range?
- What's your ideal timeline?
- Do you need permits? (Most structural, electrical, and plumbing work does)
- Are you flexible on materials, or do you have specific requirements?
💡 Pro Tip: The more specific you are about your project, the more accurate quotes you'll receive.
Step 1: Find Potential Contractors
Where to Look
✅ Recommended Sources:
- Washington State contractor directories (like this one!)
- Personal referrals from neighbors and friends
- Local building supply stores (they know who does good work)
- L&I's verified contractor database
⚠️ Use With Caution:
- General online review sites (reviews can be manipulated)
- Door-to-door solicitors (legitimate contractors rarely cold-call)
- "Too good to be true" deals
How Many Quotes?
Get at least 3-5 quotes for any significant project. This gives you:
- A realistic price range
- Different perspectives on the work
- Comparison of professionalism and communication
Step 2: Verify Credentials
The Non-Negotiables
Before ANY meeting, verify these online at secure.lni.wa.gov/verify:
- Active Registration: Status must show "ACTIVE" (not expired, suspended, or revoked)
- Bond Status: Current and valid surety bond
- Insurance: Active general liability insurance on file
- Workers' Comp: Compliant (or properly exempt)
- Registration History: No major complaints or violations
For Specialty Trades
| Trade | Additional Verification |
|---|---|
| Electricians | Verify electrical contractor license + journeyman on staff |
| Plumbers | Verify plumbing certificate |
| Roofers | Verify roofing endorsement (for projects over $1,000) |
| HVAC | Ask about EPA 608 certification |
Document What You Find
Print or screenshot the verification results. Save them with your project documents.
Step 3: Questions to Ask Every Contractor
During Initial Contact
- "Are you registered with Washington L&I?"
- "What's your registration/UBI number?"
- "How long have you been in business?"
- "Do you carry liability insurance? What are your limits?"
- "Will you pull the required permits?"
- "Have you done projects similar to mine? Can I see examples?"
During the Estimate Visit
About Their Business:
- "Who will be on-site daily? Employees or subcontractors?"
- "Are your subcontractors also registered and insured?"
- "Who is my point of contact during the project?"
- "How do you handle change orders?"
About Your Project:
- "What's the realistic timeline from start to finish?"
- "What could cause delays?"
- "Will you be working on other projects simultaneously?"
- "What's included in your quote? What's not?"
About Materials:
- "What brands/products do you recommend and why?"
- "Where do you source materials?"
- "Can I provide any materials myself?"
About Payment:
- "What's your payment schedule?"
- "Do you require a deposit? How much?"
- "What forms of payment do you accept?"
References
Ask for and actually call at least 3 references:
- Similar project type
- Similar project size/budget
- Completed within the last 1-2 years
Questions for References:
- "Would you hire them again?"
- "Did they stay on budget? On schedule?"
- "How did they handle problems that came up?"
- "Were they easy to communicate with?"
- "Did they clean up after themselves?"
Step 4: Red Flags to Watch For
Immediate Deal-Breakers 🚩
Run away if the contractor:
- ❌ Won't provide their L&I registration number
- ❌ Can't show proof of insurance
- ❌ Asks for more than 20% down (or full payment upfront)
- ❌ Offers a big discount for paying in cash
- ❌ Pressures you to sign immediately
- ❌ Says permits "aren't necessary" for your project
- ❌ Has no physical business address
- ❌ Won't provide a written contract
Warning Signs 🟡
Proceed with caution if:
- Quote is significantly lower than all others (30%+ below average)
- They can "start tomorrow" on a major project
- Communication is poor from the start
- They're evasive about subcontractors
- They have no online presence whatsoever
- The company is very new (under 2 years)
- They've changed business names recently
Trust Your Gut
If something feels off, it probably is. A good contractor understands that trust takes time to build and won't pressure you.
Step 5: Understanding the Quote
What Should Be Included
A professional quote should contain:
✅ Contractor Information:
- Company name, address, phone
- Registration/license numbers
- Contact person name
✅ Scope of Work:
- Detailed description of ALL work to be performed
- Specific materials (brands, models, quantities)
- What's explicitly NOT included
✅ Pricing:
- Line-item breakdown (not just a lump sum)
- Labor costs
- Material costs
- Permit fees
- Contingency allowance (if applicable)
✅ Timeline:
- Estimated start date
- Project duration
- Milestones for payment
✅ Terms:
- Warranty information
- Payment schedule
- Validity period for the quote
Comparing Quotes
Don't just compare the bottom line. Consider:
| Factor | Weight |
|---|---|
| Total Price | 30% |
| Detailed Scope | 20% |
| Timeline | 15% |
| Contractor Reputation | 20% |
| Communication Quality | 15% |
💡 The cheapest bid often isn't the best value. Factor in quality, reliability, and warranty.
Step 6: The Contract Essentials
Must-Have Elements
Your written contract should include:
- Full legal names of all parties
- Contractor's registration number
- Complete scope of work (attach detailed specs)
- Materials specifications (brands, colors, models)
- Total contract price (or not-to-exceed amount)
- Payment schedule tied to milestones
- Start and completion dates
- Permit responsibilities (who pulls them, who pays)
- Change order process (must be in writing)
- Warranty terms (workmanship AND materials)
- Insurance requirements
- Dispute resolution process
- Cancellation clause (3-day right to cancel in WA)
- Cleanup responsibilities
- Signatures and dates
Washington-Specific Requirements
Under Washington law (RCW 18.27), your contract MUST include:
- Contractor's registration number
- Statement about the contractor's bond
- Notification of your right to check registration status
- 3-day cancellation notice for door-to-door sales
What to Avoid
Never sign a contract that:
- ❌ Is handwritten or vague
- ❌ Has blank spaces to "fill in later"
- ❌ Doesn't specify materials
- ❌ Requires signing immediately
- ❌ Waives your legal rights
- ❌ Makes you responsible for permits
Step 7: Payment Best Practices
Recommended Payment Structure
| Phase | Typical Payment | Purpose |
|---|---|---|
| Deposit | 10-20% | Materials ordering |
| Start of Work | 25-30% | Mobilization, demolition |
| Midpoint | 25-30% | Progress milestone |
| Near Completion | 15-20% | Finishing work |
| Final | 10-15% | After final inspection/walkthrough |
Payment Rules
✅ DO:
- Make payments by check or credit card (creates paper trail)
- Pay only after work is completed to your satisfaction
- Hold final payment until ALL work is done, inspected, and you're satisfied
- Get lien releases with each payment
❌ DON'T:
- Pay cash (no record = no recourse)
- Pay more than 20% upfront for most projects
- Pay ahead of work completed
- Make the final payment until punch list is complete
Lien Protection
When you pay a contractor, suppliers and subcontractors can still file liens against your property if they weren't paid. Protect yourself:
- Request lien releases with each progress payment
- Verify subcontractors are paid before final payment
- Consider joint checks made out to contractor AND supplier
- For large projects: Use an escrow account
Step 8: During the Project
Stay Engaged (But Not in the Way)
- Conduct regular check-ins (weekly for large projects)
- Document progress with photos
- Address concerns immediately
- Approve any changes IN WRITING
- Keep all receipts and communication
Change Orders
Changes happen. Handle them correctly:
- Get it in writing before work proceeds
- Include: Description, cost impact, timeline impact
- Both parties sign the change order
- Keep copies with your contract
Problem Resolution
If issues arise:
- Communicate calmly and document the issue in writing
- Give contractor opportunity to fix the problem
- Reference the contract for agreed-upon standards
- If unresolved: File complaint with L&I (protects your bond claim rights)
Step 9: Project Completion
Final Walkthrough Checklist
Before making final payment:
- All contracted work is complete
- Quality meets contract specifications
- Permits have been signed off by inspector
- Certificate of Occupancy (if applicable)
- All debris removed, site is clean
- Equipment and appliances work properly
- Touch-up paint and finishing complete
Documents to Collect
Get these from your contractor:
- Final lien release
- Warranty information (written)
- Maintenance instructions
- Product manuals and specs
- Final inspection sign-off
- Before/after photos
- Contact info for warranty claims
After the Project
- Leave a review (honest reviews help other homeowners)
