NW Blue Diamond has a deeply polarized review history, with a near-even split between glowing 5-star reviews and damning 1-star reviews, which is itself a red flag noted by one reviewer. Professionalism scores are dragged down significantly by multiple accounts of no-shows, failure to return calls, a plumber making inappropriate gestures, and refusal to honor promises to return and fix poor work. Pricing is a serious concern, with multiple reviewers describing overcharging, price gouging on flood restoration work, suggesting cash payments to avoid tax, and one confirmed case of a fraudulent upsell of a non-existent leak to a senior citizen. Project completion is the weakest dimension, with multiple reviews describing abandoned work, refusal to return for callbacks, incomplete finishing, and one reviewer being unable to reach the company at all after a dispute. Experience scores are mixed — some reviewers praise the quality of specific jobs, but others document incorrect installations, sloppy paintwork, damaged tile from improper tool use, and use of substandard components.
