Red Flags: Warning Signs of Problematic Flooring Contractors

Immediate Disqualifiers

  • No L&I registration: Cannot verify at lni.wa.gov/licensing
  • No physical business address: PO Box only is a warning sign
  • Demands cash only: Legitimate contractors accept multiple payment forms
  • Won't provide written contract: Required by Washington law for projects over $1,000
  • Pressure to sign immediately: "This price is only good today"
  • No warranty offered: Quality flooring work should include installation warranty

Yellow Flags (Proceed with Caution)

  • No portfolio or references: May be new, but harder to verify quality
  • Unwilling to pull permits: Permits aren't always required for flooring, but evasiveness is concerning
  • Extremely low bids: Below-market pricing often means cut corners
  • Large upfront deposit requests: Industry standard is 10-30%, not 50%+
  • No insurance certificate: Should provide current COI upon request
  • Won't specify materials: Vague about brands or grades being used

Common Flooring Scams in Washington

Bait and Switch Materials: Contractor quotes premium materials, installs builder-grade alternatives. Always get material brands and grades in writing.

Moisture Barrier Skip: In Western Washington's humid climate, moisture barriers are essential. Some contractors skip this step to cut costs, leading to warped floors and mold.

Subfloor Neglect: Failing to properly assess and repair subfloor issues leads to premature flooring failure. Quality contractors always evaluate subfloor condition.

"Leftover Materials" Discounts: Scammer claims to have materials left from another job at a steep discount. Usually means stolen or defective materials.

How to Verify a Washington Flooring Contractor

Step 1: L&I License Verification

Visit lni.wa.gov/licensing and search for the contractor. Verify:

  • Active registration status
  • Current bond and insurance
  • No pending complaints or violations
  • Business name matches who you're dealing with

Step 2: Get Their UBI Number

Ask for their Washington State UBI (Unified Business Identifier). Verify at dor.wa.gov that:

  • Business is registered and active
  • Business type matches expectations (LLC, Corporation, etc.)
  • They're registered to collect sales tax

Step 3: Request Insurance Certificate

Ask for a current Certificate of Insurance (COI) showing:

  • General liability coverage (minimum $1,000,000 recommended)
  • Workers' compensation (if they have employees)
  • Your name as "certificate holder" for your project

Step 4: Check Reviews and References

  • Google Business Profile: Look for patterns in reviews, not just star ratings
  • BBB: Check for complaints and resolution history
  • Direct references: Ask for 3 recent flooring projects and actually call them
  • Houzz/Angi: Industry-specific reviews from verified customers

Step 5: Verify Physical Location

  • Visit their business address if possible
  • Google Street View to verify it's a real business location
  • Established businesses have inventory, showrooms, or professional office space

Choosing the Right Flooring for Washington Homes

Western Washington (Seattle, Tacoma, Olympia, Bellingham)

The wet, mild climate of Western Washington creates specific flooring challenges:

Best Choices:

  • Luxury Vinyl Plank (LVP): 100% waterproof, stable in humidity changes
  • Tile: Porcelain especially durable, moisture-proof
  • Engineered Hardwood: More dimensionally stable than solid wood in humidity
  • Polished Concrete: Excellent for radiant heat, no moisture concerns

Use with Caution:

  • Solid Hardwood: Can cup, crown, or gap with humidity swings
  • Laminate: Not waterproof; moisture in subfloor causes swelling
  • Cork: Requires excellent moisture control

Avoid:

  • Bamboo (strand-woven): Extremely sensitive to PNW humidity

Eastern Washington (Spokane, Tri-Cities, Wenatchee)

Drier climate with greater temperature extremes:

Best Choices:

  • Solid Hardwood: Low humidity reduces expansion/contraction issues
  • Engineered Hardwood: Works great in all Eastern WA climates
  • Tile: Excellent for radiant heat (common in Eastern WA)
  • LVP: Temperature stable, works well

Special Considerations:

  • Radiant floor heating is more common—choose compatible materials
  • Static electricity issues in dry winters—carpet may cause problems
  • Direct sunlight fading is more intense—factor into material selection

High-Moisture Areas (Bathrooms, Kitchens, Basements)

For any area with potential water exposure:

Recommended:

  • Porcelain or ceramic tile
  • Luxury vinyl plank or tile
  • Polished or stained concrete
  • Sheet vinyl

Not Recommended:

  • Solid hardwood
  • Laminate
  • Carpet
  • Untreated cork or bamboo

The Flooring Contractor Bidding Process

Getting Quality Bids

Get 3-5 bids from licensed contractors. For accurate comparison:

  1. Have contractors visit in person: Accurate bids require seeing the actual space
  2. Specify exactly what you want: Material type, brand, grade, room(s), and extras
  3. Ask identical questions: Ensure you're comparing apples to apples
  4. Get everything in writing: Verbal promises don't count

What Your Flooring Bid Should Include

  • Line-item pricing: Materials, labor, removal, prep work, trim, transitions
  • Material specifications: Brand, product line, color/style, and grade
  • Subfloor assessment: What they'll do if issues are found
  • Timeline: Start date, estimated completion
  • Warranty: Both materials (manufacturer) and labor (contractor)
  • Payment schedule: Deposit, progress payments, final payment
  • Change order process: How additions/changes will be priced

Comparing Bids Effectively

Don't automatically choose the lowest bid. Compare:

Factor Weight
Total price 25%
Material quality specified 20%
Contractor reputation/reviews 20%
Timeline/availability 15%
Warranty terms 10%
Communication quality 10%

A contractor who is slightly more expensive but uses better materials, has great reviews, and communicates clearly is often worth the premium.

Washington Flooring Contract Requirements

What Washington Law Requires

For contracts over $1,000, Washington law (RCW 18.27.114) requires:

  • Contractor's name, address, phone number, and L&I registration number
  • Description of the work to be performed
  • Total contract price (or how it will be calculated)
  • Payment terms and schedule
  • Approximate start and completion dates
  • Notice of the right to file a complaint with L&I

What You Should Also Include

Beyond legal minimums, your contract should specify:

  • Detailed scope of work: Rooms, square footage, all included work
  • Material specifications: Brand, product name, color, grade
  • Exclusions: What's NOT included (furniture moving, appliances, etc.)
  • Preparation work: Who handles subfloor repairs, leveling, moisture barriers
  • Waste removal: Who hauls away old flooring and debris
  • Protection measures: How they'll protect non-work areas
  • Final walkthrough: Process for identifying and addressing punch list items
  • Warranty details: Duration and what's covered for both labor and materials
  • Dispute resolution: Mediation or arbitration process

Payment Schedule Best Practices

Milestone Typical Percentage
Signing/deposit 10-25%
Materials delivered 25-30%
Installation 50% complete 20-25%
Final completion/walkthrough 20-25%

Never pay more than 50% before work begins. Legitimate contractors don't need heavy front-loading.

Common Flooring Installation Issues in Washington

Moisture-Related Problems

Washington's climate (especially west of the Cascades) creates unique moisture challenges:

Symptoms:

  • Cupping (edges higher than center)
  • Crowning (center higher than edges)
  • Buckling (floor lifts from subfloor)
  • Gaps between planks
  • Mold or mildew smell

Prevention:

  • Moisture testing before installation (ASTM F2170 or similar)
  • Proper moisture barrier for concrete and crawlspace applications
  • Acclimation of materials (especially wood) to your home's humidity
  • Adequate crawlspace ventilation (vents, encapsulation)

Washington-Specific: Homes with crawlspaces (common in older Western WA construction) are especially vulnerable. Ensure any flooring contractor assesses crawlspace conditions.

Subfloor Issues

  • Squeaky floors: Inadequate fastening or leveling
  • Bouncy/soft spots: Damaged or undersized joists
  • Uneven surfaces: Need leveling compound before installation
  • OSB swelling: Moisture-damaged subfloor requiring replacement

Installation Quality Issues

  • Visible seams or gaps: Poor cutting or improper expansion gaps
  • Lifting edges: Inadequate adhesive or trowel technique
  • Hollow spots (tile): Insufficient thinset coverage
  • Transition issues: Poor transitions between rooms or materials
  • Baseboard gaps: Walls not straight, requiring scribe or caulk

Questions to Ask Every Flooring Contractor

Before Hiring

  1. "What's your L&I registration number and can I see your insurance certificate?"
  2. "How many years have you been installing this type of flooring?"
  3. "Will you personally do the work or use subcontractors?"
  4. "What's your process for moisture testing and subfloor assessment?"
  5. "How do you handle unexpected subfloor damage?"
  6. "Can you provide references from jobs similar to mine?"
  7. "What's your warranty on installation labor?"
  8. "What brands of materials do you typically install?"
  9. "How long will my project take, and what could delay it?"
  10. "What's your payment schedule?"

During the Project

  1. "What did you find when you inspected/removed the old flooring?"
  2. "Do you recommend any changes based on what you're seeing?"
  3. "Are we on schedule for the completion date?"
  4. "Is this the material grade we discussed?"

At Completion

  1. "Can we do a walkthrough together to identify any issues?"
  2. "What care and maintenance do you recommend?"
  3. "When can I put furniture back on the floor?"
  4. "How do I make a warranty claim if issues arise?"
  5. "Do you have written warranty documentation for me?"

Washington Flooring Permit Requirements

When Permits Are Required

Flooring itself rarely requires a building permit in Washington. However, permits may be needed for:

  • Subfloor structural modifications: Cutting joists, adding support
  • Radiant floor heating installation: Electrical permit required
  • Bathroom/kitchen modifications: If plumbing is moved or modified
  • New construction: Part of overall building permit

When Permits Aren't Required

  • Standard flooring replacement (carpet to LVP, tile to hardwood, etc.)
  • Subfloor repair within existing structure
  • Moisture barrier installation
  • Transitions and trim work

Permit Pulling Responsibility

If permits are required, the contractor should typically handle:

  • Permit application
  • Permit fees (built into contract)
  • Scheduling inspections
  • Obtaining final sign-off

Note: Some contractors pass permit fees through as a line item. This is acceptable as long as it's disclosed upfront.

Working with Your Flooring Contractor

Before Installation Day

  • Clear the space: Move furniture and belongings from work areas
  • Secure pets: Keep them away from work zones
  • Establish access: Arrange key/code access if you won't be home
  • Identify bathroom: Show workers which facilities they can use
  • Discuss dust control: Flooring work generates dust—discuss protection

During Installation

  • Expect noise and dust: Especially during removal and cutting
  • Minimize traffic: Keep family members away from work areas
  • Daily check-ins: Brief morning or end-of-day conversations
  • Take photos: Document progress and any concerns

  3. Contact the contractor in writing: Email or certified letter
  4. Allow reasonable time to respond: 10-14 business days
  5. Request a site visit: Discuss issue in person if possible

Formal Complaint Options
