Some chimney operators in the Seattle area register two, three, or more distinct business names — each with its own website, Google Business Profile, and phone number — but dispatch the same technicians from the same address. A homeowner who calls two of those names hoping for a second opinion may unknowingly be talking to the same company twice. The cross-checks below take less than fifteen minutes and can expose that overlap before you book.
Why This Happens in the Seattle Market
Washington State makes it straightforward to register a trade name (DBA) through the Department of Revenue. For a modest filing fee, one LLC can operate under several distinct public-facing brands simultaneously. Each brand can accumulate its own Google reviews, run its own ads, and appear to be a separate business to anyone who does not look deeper.
The practice is not automatically illegal, but it does create a consumer-protection problem: you lose the ability to get a genuinely independent second opinion, and you may not realize that a pattern of complaints against one brand name is connected to the company quoting you under a different name.
This dynamic is worth understanding alongside the broader issue of paid placement — the fact that top of Google isn't the best chimney company — it's who paid. Shell brands often run separate ad campaigns for each name, compounding the illusion of a crowded, competitive market.
An Illustrative Scenario
*The following is a hypothetical teaching example, not a real customer account.*
Sandra, a homeowner in Shoreline, notices her firebox mortar is cracking and wants to understand her options before calling anyone. She searches for chimney companies, finds two that look different — different logos, different review counts, different phone numbers — and calls both for estimates. The first quote comes in at $1,400; the second at $1,250. She feels reassured that the prices are in the same ballpark. What she does not yet know: both numbers ring the same dispatch desk. The technician who arrives for the second appointment is the person who gave her the first quote. She has not gotten a second opinion; she has gotten the same opinion presented twice under different branding.
The Five Identifiers to Cross-Check
Before you accept any quote, gather the following information from every company you contact. Then compare them side by side.
1. Washington State Contractor License Number The Department of Labor & Industries contractor license lookup (secure.lni.wa.gov) shows the legal entity behind a license. Two different brand names pointing to the same license number — or to different licenses registered to the same LLC — are a direct signal of shared ownership.
2. UBI Number Washington's Unified Business Identifier is assigned to the legal entity, not the trade name. Search the Secretary of State's business lookup at sos.wa.gov. If two company names resolve to the same UBI, they are the same business.
3. Physical Address Ask for the company's physical service address — not just a P.O. box or a Google Maps pin. Matching addresses across two supposedly separate companies confirm a shared operation. Be aware that virtual office addresses in SoDo or Bellevue are sometimes used to create geographic variety across brand names.
4. Insurance Certificate Request a certificate of general liability insurance. The named insured on that certificate is the legal entity actually holding coverage. If two brands name the same insured entity, they share the same insurance — and the same business.
5. Phone Number Forwarding Call both numbers at the same time from two phones. If one goes to voicemail when the other connects, or if the person who answers uses a generic greeting rather than the specific brand name, that is worth noting. Cross-reference both numbers in a reverse-phone lookup.
Quick-Reference: Red Flag vs. Green Flag Matrix
| Identifier | Green Flag | Red Flag |
|---|---|---|
| WA Contractor License | Unique license per brand, active & current | Same license number behind two brand names |
| UBI Number | Distinct UBI for each company | Identical UBI across two "different" companies |
| Physical Address | Street address, verifiable on Maps | P.O. box only, or identical address to another brand |
| Insurance Named Insured | Matches the brand name you called | Names a different LLC than the brand you called |
| Google Business Profile age | Profile active 3+ years | Profile created within past 6–12 months, few reviews |
| Technician CSIA credential | Technician provides CSIA number on request | Credential claimed on website but not provided in person |
Typical Seattle Chimney Quote Ranges
Knowing realistic price bands helps you judge whether quotes are genuinely independent. If two companies quote identically on a non-standard repair, that may indicate a shared pricing sheet.
| Service | Typical Seattle Range |
|---|---|
| Level 1 inspection | $100–$200 |
| Level 2 inspection (with video scan) | $200–$400 |
| Standard sweep (wood-burning) | $150–$300 |
| Flue relining (stainless liner, per foot) | $85–$150 per linear foot |
| Firebox repointing | $300–$700 |
| Full crown rebuild | $500–$1,200 |
*These are typical market ranges for the Seattle / Puget Sound area based on publicly available service listings; your actual quote will depend on chimney height, condition, and access.*

How the Ranking Accounts for This
The ranking this site maintains scores companies on eight public measures, including license and insurance verification. A company whose license resolves to an entity operating under multiple active brand names without disclosure is flagged in the public-complaints dimension. That scoring does not replace your own five-point cross-check, but it provides a starting baseline before you make any calls.
What to Do If You Spot Overlap
If your cross-check reveals that two companies share a UBI or license number, you have two straightforward options. First, treat them as one company and look elsewhere for a genuine second opinion. Second, if you believe the arrangement was used to mislead you — for example, if a technician denied a connection when asked directly — you can file a complaint with the Washington State Attorney General's Consumer Protection Division (atg.wa.gov) and with the Better Business Bureau's Northwest + Pacific office.
Frequently asked questions
- How can I tell if two Seattle chimney companies are actually the same business?
- Look up both companies' Washington State contractor license numbers at the L&I contractor lookup and their UBI numbers at the Secretary of State business search. If either identifier matches across two brand names, they are the same legal entity. Matching physical addresses on their insurance certificates confirm it further.
- Is it illegal for a chimney company to operate under multiple names in Washington State?
- Registering multiple trade names (DBAs) under one LLC is legal in Washington. It becomes a consumer-protection problem — and potentially an unfair business practice under Washington's Consumer Protection Act — if the operator actively denies the connection when a customer asks, or uses the arrangement to suppress or dilute complaint records.
- What is the quickest single check I can do before calling a Seattle chimney company?
- Search the company's exact business name in the Washington Secretary of State's business lookup (sos.wa.gov) and note the UBI number. Then search the owner's name or address in the same database to see whether other active trade names share that identifier. This takes roughly five minutes and costs nothing.
