How to check a Washington contractor before signing

Start with registration, not a trade name

Washington requires construction contractors to register with Labor & Industries. Registration is not the same as a competency license: L&I's consumer guide states that the state does not require a skills test for ordinary contractor registration, while electricians, plumbers, and certain other trades have separate licensing or certification requirements. An active registration confirms baseline state requirements; it does not certify workmanship or make a contractor appropriate for a particular retaining-wall system.

Search L&I Verify using the contractor registration number printed on the estimate or proposal. Compare the result with the exact legal business name, owner information, UBI, registration classification, effective and expiration dates, and any listed specialties. A familiar brand name or a nearly matching company name is not enough. The entity signing the contract, the entity shown on the bid, and the entity in Verify should be the same legal contractor.

Reopen Verify close to the signing date and again before work begins. L&I says its public database is updated on business days but also warns that portions can be incomplete or not current. A dated snapshot on this site is evidence of what was reviewed at that time, not a substitute for the current state record.

Read registration, bond, insurance, and workers' compensation separately

L&I Verify exposes several different records. Contractor registration, surety bond, general liability insurance, and workers' compensation status answer different questions. L&I advises homeowners to confirm an active registration and valid bond and insurance. If a contractor has employees, Verify can also show whether the workers' compensation account is active and paid to date.

Do not collapse these fields into a single ‘verified’ badge. A registration may become suspended when a required bond or insurance policy expires or is cancelled, or when other registration requirements are not met. Conversely, an active registration means the registration requirements shown by L&I were met at that time; L&I explicitly says hiring a registered contractor does not guarantee that problems will not happen.

For a large project, read the underlying bond and insurance sections rather than relying on a summary. Note carrier names, effective dates, expiration dates, and history. Liability insurance and a contractor bond serve different purposes and have limits; neither is a warranty for the finished wall.

Do not turn every public record into the same warning

Verify may show lawsuits against a bond, license or registration violations, safety citations, contractor strikes, debarment information, and workers' compensation status. These categories are not interchangeable. A bond-lawsuit entry records that a lawsuit was filed against the bond or assigned savings account; the entry should not be described as a workmanship finding without reading the available disposition. A safety inspection is also not, by itself, the same thing as a cited violation—the relevant section is the resulting violation history.

Look at dates, status, repetition, and relevance. An old resolved matter, an active debarment from public works, an expired insurance record, and a current registration violation require different explanations. If a record is material to the hiring decision, open its detail and ask the contractor for context and documentation instead of relying on a generic risk label.

Compare written bids and make changes in writing

L&I recommends obtaining at least three written bids and comparing more than price. Its Hire Smart guidance specifically calls out scope, warranties, references, completion dates, and price. For wall and slope work, normalize responsibility for engineering, permits, excavation, temporary shoring, drainage, soil export, access restoration, inspections, materials, and final close-out before comparing totals.

The contract should identify the legal contractor, registration number, detailed scope, exclusions, materials, start and completion expectations, payment schedule, warranty, permit responsibility, and how changes are approved. L&I recommends putting changes to material or scope in writing and warns against paying the full amount before the job is complete. For contracts over $1,000, Washington law generally requires a contractor disclosure statement; the L&I problems page explains that requirement and available remedies.

Public records narrow uncertainty; they do not select the contractor for you. References for similar walls, the proposed engineer, a clear drainage path, and a bid that explains exclusions are still part of the decision. Keep the proposal, registration check, plans, change orders, inspection records, and payment documentation together.
