The Verdica score is a composite trust score from 300 to 850, computed from workplace safety inspections and 50-state contractor licensing maintained by OSHA and state licensing boards. A score of 839 places WHITE KNIGHT PLUMBING in WA in the excellent (800–850) band. The score reflects publicly available regulator data — it is not a rating from Verdica itself and does not incorporate paid reviews or advertising.
Verdica combines three weighted sub-scores drawn from OSHA and state licensing boards. Each sub-score reflects a different dimension of construction compliance — OSHA inspection outcomes, citations, and license status across states — and is normalized against industry peers before being aggregated to the 300–850 scale.
Verdica pulls public records from OSHA and state licensing boards: workplace safety inspections and 50-state contractor licensing. Data is refreshed on rolling cycles, typically weekly to monthly depending on the source agency's own update schedule. See the "source data current" indicator on the entity page for the last successful refresh.
Common negative signals include serious or willful OSHA citations, suspended licenses, or repeat violations. Any of these appear in the underlying regulator records and pull the sub-score down; the composite reflects the weighted impact.

Since moving to Lacey in 2014, I have relied on White Knight Plumbing multiple times for projects both large and small. My experience with the owner, Chris, is that he is knowledgeable, experienced, and very fair in his pricing. I had a small project today—a hose bib replacement—and the two repair folks, Ray and Aaron, were great -- very friendly, efficient, and helpful -- including providing additional information and useful recommendations. Without hesitation, I highly recommend White Knight Plumbing!

Wonderful fast service, great experience and will definitely use them again!
Very responsive and got us right in the schedule. Will definitely use them again. Very friendly and respectful of our home. Thank you White Knight.
Replaced broken garbage disposal. Got a quote easily over the phone and was over $100 less than others. They had an opening within days of my call. The service included a replacement disposal they had on hand. The team showed up early (!), treated me and my home respectfully, were friendly, and very fast without compromising on quality work. White Knight are always on my short list when I need plumbing.
The company was quick and responsive to our calls. Kevin and Aaron came, explained everything clearly and followed through with the work in professional and respectful manner! Will be using them again for any other plumbing needs. Definitely recommend!
Great experience with Hans and Kyle their knowledge and professionalism was worth every bit of the time it took to replace the kitchen sink. In addition the care that they gave to the new countertops was very important to us and obviously very important to them I would rate this as a five-star experience
Excellent service! They got to work immediately & took care of the problem! They were professional & friendly!
