Washington's Department of Labor & Industries maintains a free, public contractor registration database. Any chimney company doing repair or construction work in Seattle must hold a current registration under RCW 18.27—and you can verify it in about sixty seconds before you book, not after you've handed over a check. Skipping this step is one of the most common ways Seattle homeowners lose consumer-protection rights they didn't know they had.
Why This Matters Right Now
Fall is the busiest season for chimney work in the Pacific Northwest. Fireplaces that sat idle through the summer start seeing heavy use as October rain sets in, and companies that operate year-round get supplemented by seasonal operators of uncertain standing. That timing mismatch—high demand, loosened scrutiny—is exactly when unregistered contractors tend to knock.
Consider a hypothetical that plays out more often than it should. Edward, a Ballard homeowner, gets a door-knock in late September from a crew offering a steep discount on a chimney inspection. They seem professional, leave a business card, and the price is hard to argue with. Edward pays a deposit the same day. Two weeks later, when a dispute arises over whether relining is actually necessary, he tries to file a complaint—and discovers the company has no L&I registration number. His leverage, at that point, is nearly zero. *(This is an illustrative scenario, not a real customer account.)*
What Washington Law Actually Requires
Under RCW 18.27, any contractor performing chimney repair, rebuilding, or installation for compensation must be:
- Registered with Washington L&I (a UBI-linked contractor registration number)
- Bonded — a $12,000 minimum bond that covers consumer financial losses
- Insured — general liability coverage of at least $50,000 per occurrence
These are three separate requirements, not one. A company can carry its own liability insurance policy and still be unregistered. Registration is what ties the bond and insurance to a public, searchable record the state can enforce against.
The Exact Lookup Steps
1. Go to secure.lni.wa.gov/verify (Washington L&I's Contractor Verify tool). 2. Enter the company name or, if you have it, the contractor registration number (it begins with a two-letter business-type code followed by digits, e.g., *SMITHCS831BQ*). 3. Check that Status reads *Active* — not *Expired*, *Suspended*, or *Cancelled*. 4. Confirm the Bond and Insurance columns both show current, not lapsed. 5. Note the expiration dates; some registrations renew annually and can lapse mid-project.
The search is free, requires no account, and takes under a minute on a phone.
What the Numbers Look Like
| Registration Status | Bond on File | What It Means for You |
|---|---|---|
| Active | Yes | Full RCW 18.27 consumer protections apply |
| Active | No / Lapsed | Registered but bond gap — proceed with caution |
| Expired | — | No protection; any contract may be unenforceable |
| Not Found | — | Unregistered; state has no recourse mechanism |
| Suspended | — | Prior violation; do not hire until reinstated |
For context, typical Seattle chimney service prices run $150–$300 for a sweep and inspection, $500–$1,500 for minor repairs, and $2,500–$6,000+ for full relining — ranges where losing your deposit to an unregistered crew is a genuinely painful outcome. These are typical market ranges, not a guarantee of any specific quote.
Red Flags Before You Even Run the Lookup
If a company pressures you to pay in full before work begins, offers only cash payment, or can't produce a registration number on request, treat that as a signal to verify immediately. Our article on chimney repair red flags covers the broader pattern of tactics that often accompany unlicensed work. And if you found this company through a paid Google ad, it's worth reading Top of Google Isn't the Best Chimney Company — It's Who Paid before you call.
How Registration Fits Into a Broader Evaluation
Registration is a legal floor, not a quality ceiling. A company can be fully registered and still do mediocre work. That's why the ranking on this site layers seven additional public measures—Google rating, BBB standing, technician credentials, response time, and others—on top of the license-and-insurance check. Think of the L&I lookup as the first gate: if a company doesn't pass it, nothing else matters. If it does, you move on to comparing quality.
Run the lookup before you schedule. It costs you sixty seconds and potentially saves you thousands.
Frequently asked questions
- Where do I look up a chimney contractor's Washington State registration?
- Go to secure.lni.wa.gov/verify, enter the company name or registration number, and confirm the status reads 'Active' with a current bond and insurance on file. The tool is free and requires no login.
- What is the difference between a registered, bonded, and insured contractor in Washington?
- Under RCW 18.27, these are three separate requirements. Registration is the state record linking a business to L&I. The bond (minimum $12,000) covers consumer financial losses if the contractor defaults or causes damage. Insurance (minimum $50,000 per occurrence) covers liability for injuries or property damage. All three must be current for full consumer protections to apply.
- Can I still file a complaint if I paid an unregistered chimney contractor in Seattle?
- Your options are significantly limited. L&I's bond and enforcement mechanisms only apply to registered contractors. You may still pursue a civil small-claims action, but the state has no direct recourse tool against an unregistered company. This is why verifying registration before payment—not after a dispute—is critical.
