How to Find a Reliable Contractor in Washington: A Step-by-Step Vetting Process

Finding a good contractor in Washington shouldn't feel like gambling. Yet many homeowners hire based on little more than a Google search and a friendly phone call—then wonder why things go wrong.

This guide gives you a systematic, step-by-step process for finding and vetting contractors in Washington State. Follow these steps and you'll dramatically reduce your risk of hiring someone who'll do poor work, overcharge you, or disappear mid-project.

Step 1: Define Your Project Clearly

Before you contact any contractor, get clear on what you need:

Write a Project Scope

Document:

• What work needs to be done (be specific)
• What outcome you expect (not just "new bathroom" but "new bathroom with walk-in shower, double vanity, heated floors")
• Any specific materials or brands you want
• Timeline requirements (move-in date, event deadline, etc.)
• Budget range (know what you can realistically spend)

Determine License Type Needed

Different projects require different specialties:

Project	License Type(s) Needed
General remodeling	General contractor
Electrical work	Electrical contractor
Plumbing	Plumbing contractor
HVAC	HVAC/mechanical contractor
Roofing	General or roofing specialty
Painting/flooring	General contractor (or handyman if under $2,000)

Some general contractors hold multiple specialty endorsements. For large projects involving multiple trades, a general contractor coordinates everything.

Step 2: Gather Initial Candidates

Cast a wide net initially, then narrow down. Aim for 5-8 candidates to research, knowing you'll narrow to 3-4 for bids.

Best Sources for Contractor Names

Personal referrals (highest quality source):

• Ask neighbors who've had similar work done
• Ask friends and family in the area
• Ask local real estate agents (they know who does quality work)
• Ask your home inspector (if you've had an inspection)

Professional referrals:

• Ask your architect or designer
• Ask specialty contractors for referrals outside their scope
• Ask building supply stores (they see who buys quality materials)

Online research:

• Use our Washington Contractor Directory (L&I verified)
• Check Google reviews (look for detailed reviews, not just ratings)
• Read Nextdoor recommendations
• Check Houzz for portfolio and reviews

Red Flags in Initial Research

Immediately disqualify contractors who:

• Don't have a Washington contractor's license
• Have license in "suspended" or "inactive" status
• Don't answer calls or return messages within 24-48 hours
• Push back on providing license number
• Don't have a physical business address
• Cash-only (suggests tax issues)

Step 3: Verify Washington Contractor Licensing

This step is non-negotiable. Every contractor performing work over $2,000 in Washington must be registered with L&I.

How to Check a License

1. Go to verify.lni.wa.gov
2. Search by business name or UBI number
3. Review the contractor's record

What to Look For

License status:

• "Active" = Good
• "Suspended," "Expired," "Cancelled" = Do not hire

Bond status:

• Must show active bond
• Verify bond amount is adequate for your project (minimum $12,000, up to $72,000 for some contractors)

Insurance:

• Liability insurance is required
• Some contractors carry additional coverage

License type:

• Verify they're licensed for your type of work
• "General" can do general construction
• Specialty licenses for electrical, plumbing, HVAC

Complaints and violations:

• Check for L&I complaints
• Look for patterns (one complaint in 20 years is different from five in two years)
• Read the details—what was the issue?

Document Everything

Create a simple spreadsheet:

Contractor	License #	Status	Bond Amount	Complaints	Notes
ABC Construction	ABCCO123AB	Active	$12,000	0	Good reviews
XYZ Builders	XYZBU456CD	Active	$24,000	2	Check complaint details

Step 4: Conduct Phone Interviews

Call your top 4-5 candidates. This call serves two purposes: gathering information and gauging communication.

Questions to Ask

About their business:

• How long have you been in business?
• How many projects like mine have you completed?
• Who would be on-site doing the work? (Owner? Employees? Subcontractors?)
• Are you currently taking on new projects? What's your typical timeline?

About your project:

• Have you done this type of work before?
• Do you anticipate any challenges with this project?
• What permits will be required?
• Will you pull the permits, or do I need to?

About process:

• Can you provide a detailed written bid?
• How do you handle changes during the project?
• What's your payment structure?
• What warranty do you offer on your work?

Red Flags in Phone Conversations

Be wary of contractors who:

• Won't commit to pulling permits
• Offer unusually low prices or "cash discounts"
• Push for large upfront deposits (more than 10%)
• Can't answer specific questions about the work
• Pressure you to decide quickly
• Speak negatively about all other contractors
• Won't provide references

Green Flags

Positive signs:

• Ask thoughtful questions about your project
• Are honest about timeline and potential challenges
• Have been in business for 5+ years
• Employ their own workers (vs. all subcontractors)
• Mention permits without being asked
• Have a clear process and communicate it well

Step 5: Request and Evaluate Bids

Request written bids from your top 3-4 candidates.

What a Good Bid Includes

• Detailed scope of work (not just "remodel bathroom")
• Itemized costs (labor, materials, permits, etc.)
• Specific materials (brand, model, quality level)
• Timeline (start date, milestones, completion)
• Payment schedule (tied to milestones, not arbitrary dates)
• What's excluded (just as important as what's included)
• Warranty information

How to Compare Bids

Don't just compare bottom-line prices. Look at:

Scope completeness:

• Does each bid cover the same work?
• Is one including things others aren't?
• What's excluded that you'll need?

Material quality:

• Are they specifying the same quality level?
• Is one using builder-grade while another uses premium?
• Are allowances realistic?

Labor breakdown:

• Is labor priced reasonably for the work?
• Does timeline seem realistic?

Hidden costs:

• What about permits and inspections?
• Dumpster and debris removal?
• Final cleaning?

Understanding Price Differences

If bids vary significantly, investigate why:

• Lowest bid: May be cutting corners, using inferior materials, or desperate for work (which raises other concerns)
• Middle bids: Often the sweet spot
• Highest bid: May include more scope, better materials, or premium reputation

A bid that's 20% or more below others should raise questions, not celebration.

Step 6: Check References

Ask each finalist for 3-5 references from similar projects.

Questions for References

About the project:

• What work did they do for you?
• When was the project completed?
• Was the project completed on time? On budget?

About quality:

• Are you satisfied with the quality of work?
• Did anything need to be fixed or redone?
• How did they handle any problems that arose?

About communication:

• How was communication throughout the project?
• Were they responsive when you had questions?
• Did the crew show up when expected?

About the experience:

• Would you hire them again?
• Is there anything you wish you'd known beforehand?
• Any advice for someone hiring them?

Beyond Provided References

References are self-selected—of course they'll be positive. Go further:

• Search for past reviews online (Google, Yelp, Houzz)
• Ask to see a recent completed project (drive by, or visit if owner agrees)
• Check BBB for complaints (noting BBB accreditation is paid, not earned)
• Search their name + "complaint" or "problem" online

Step 7: Meet in Person

Before signing a contract, meet your top candidate in person, ideally at the project site.

What to Observe

Professionalism:

• Do they show up on time?
• Are they prepared with questions and notes?
• Do they listen to what you want?

Knowledge:

• Do they notice things you missed?
• Can they explain technical aspects clearly?
• Do they offer suggestions based on experience?

Chemistry:

• Do you feel comfortable with them?
• Do you trust them in your home?
• Can you communicate effectively?

Questions for the In-Person Meeting

• Walk me through how this project would go day by day
• Who will be on-site each day?
• How will you protect my home during construction?
• How do you handle cleanup?
• What happens if we hit an unexpected problem?
• How should I communicate with you during the project?

Step 8: Finalize the Contract

Never start work without a written contract. In Washington, contracts over $1,000 require:

Required Contract Elements

• Contractor's name, address, and license number
• Total price or hourly rate
• Scope of work
• Payment schedule
• Timeline for completion
• Materials to be used
• Warranty terms
• Customer's notice of right to a lien

Additional Elements to Include

• Change order process (how changes are priced and approved)
• Dispute resolution method
• Insurance requirements
• Permit responsibility
• Cleanup requirements
• Final walk-through process

Payment Structure Best Practices

Recommended:

• 10% deposit to start
• Progress payments tied to milestones (not dates)
• 10% holdback until final completion and your approval

Avoid:

• More than 1/3 upfront
• Large payments before work is visible
• Final payment before final walk-through
• Cash payments (no paper trail)

Step 9: Protect Yourself During the Project

Once work begins:

Monitor Progress

• Visit the site regularly
• Take photos of work in progress
• Ask questions if something looks wrong
• Address concerns immediately, not at the end

Document Everything

• Keep all communication in writing (email or text)
• Document any agreed-upon changes
• Sign change orders before additional work begins
• Keep copies of all payments

Verify Permits and Inspections

• Confirm permits were pulled
• Verify inspections happen when required
• Get copies of inspection approvals
