Find Nearby Plumbers In Seattle, Washington

Kaizen Plumbing demonstrates strong performance across all measured dimensions. Professionalism is consistently praised with mentions of responsiveness, communication, politeness, and attention to detail across all four reviews. Project completion is exceptionally strong, with all reviews confirming on-time delivery, on-budget work, and complete follow-through on complex projects. Experience and technical skill are well-documented, with reviewers highlighting problem-solving ability and code compliance. Pricing receives a lower score due to limited mentions (only 2 reviews) and one explicit complaint about lack of itemized invoicing, though both mentions describe fair pricing overall.

• All four reviews are 5-star or 4-star ratings with no negative reviews, which is statistically unusual and warrants caution
• All reviews are from a narrow date range (May-June 2023), limiting recency assessment
• Pricing dimension based on only 2 mentions; one review explicitly criticizes lack of invoice transparency despite fair pricing claim
• Sample size of 4 reviews is small; confidence levels are moderate at best

This WW Score of 89.3 should be treated with moderate caution due to the small sample size (4 reviews) and absence of any negative feedback, which may not be fully representative of typical customer experience. The score is reliable for identifying strong professionalism and project completion, but pricing assessment is limited and should not be heavily weighted in decision-making.

Schmitty's/1st Response demonstrates strong professionalism with consistent punctuality, courteous communication, and responsive scheduling across 38 reviews. Project completion is reliable with most jobs finished as promised, though a few callbacks were needed. However, pricing emerges as a significant weakness: multiple reviews (18 mentions) reveal hidden charges, warranty-contingent add-ons, and quotes substantially higher than advertised, particularly for water heater installations where additional parts ($500-$600+) were not disclosed upfront. Technical experience is solid with skilled diagnostics and quality workmanship, but pricing transparency issues substantially drag down the overall score.

• PRICING TRANSPARENCY ISSUE: Multiple reviews (2023, 2017, 2016) report significant hidden charges and warranty-contingent add-ons not disclosed in initial quotes. Angie's List advertised prices ($799) frequently resulted in final bills $500-$600+ higher due to 'required' parts and warranty conditions.
• DUPLICATE REVIEW DETECTED: Review dated 2018-07-28 08:31:56 and 2018-07-28 00:00:00 are identical word-for-word (Brian's main line leak story). This suggests either a system error or intentional duplication. Confidence in pricing dimension slightly reduced due to potential review manipulation.
• RECENCY CONCERN: Majority of reviews (40+ of 56) are from 2016-2018, over 5 years old. Only 3 reviews from 2024 and 2 from 2023. Recent pricing complaint (2023) suggests issues may persist. Limited recent data reduces confidence in current state of business practices.
• INCONSISTENT QUALITY: One 1-star review (2019) describes crew as 'rude, inconsiderate, liars' with poor communication and abandoned work. Another 1-star (2023) alleges price gouging on parts. These outliers suggest inconsistent service quality or potential crew variation.

This WW Score of 79.8 is reliable for assessing professionalism and project completion (HIGH confidence), but the pricing dimension is significantly compromised by documented hidden charges and non-transparent quoting practices across multiple years. The score reflects a contractor with solid technical skills and professional demeanor undermined by pricing integrity concerns; prospective customers should request fully itemized quotes in writing and clarify all warranty conditions before engaging services.

Zone8 demonstrates strong performance across all measured dimensions based on available review data. Professionalism is well-supported with explicit mentions of helpful staff, prompt service, knowledgeable plumbers, and communicative teams across 4 reviews. Project completion is evidenced by timely work, quick service, and successful resolution of plumbing issues in 3 reviews. Pricing receives positive mention in 2 reviews citing fair pricing and good value. Experience is supported by references to knowledgeable staff and quality workmanship in 2 reviews. However, the small sample size (5 reviews) and limited mention counts for pricing and experience constrain overall confidence.

• All 5 reviews are 5-star ratings with no negative feedback or specific criticisms — this uniformity warrants caution
• Reviews contain generic praise language ('fantastic people,' 'great experience') with limited specific technical details
• Sample size is very small (n=5) — scores may not be representative of typical customer experience
• All reviews are from January 2024 (recent), which is positive for recency but limits historical perspective
• Pricing dimension based on only 2 mentions — confidence in that score is limited

This WW Score should be treated as preliminary and indicative only. The small sample size (5 reviews), perfect 5-star uniformity, and generic praise language suggest the score may not be fully representative of typical performance. Recommend collecting additional reviews with more specific detail before making high-stakes decisions based on this score.

Prima Plumbing has a strong overall reputation built on decades of repeat customers, skilled technicians, and a responsive office team. Professionalism scores well across the majority of reviews, with punctuality, courtesy, and communication frequently praised — however, a recurring and notable thread of complaints about a rude or dismissive phone receptionist (mentioned across multiple independent reviews spanning 2014–2023) meaningfully drags this dimension down. Project completion is generally strong, with most reviewers reporting jobs finished on time and to a high standard, though a small number of reviews cite abandoned estimates, no-shows, or unresolved issues. Experience is a clear strength — multiple reviewers specifically note that Prima correctly diagnosed problems that other plumbers missed, and long-tenured tradespeople like Pete, Jake, Wayne, and Larry are praised by name for technical skill. Pricing is the weakest dimension: while many customers find value fair and transparent, a meaningful minority of reviews cite bills that exceeded quotes significantly, charges for unresolved service calls, and hourly rates described as high — this pattern is consistent enough across years to warrant a conservative score.

• DUPLICATE REVIEW DETECTED: The review 'Prima Plumbing is the best. They have done a number of projects for us and their work has always been excellant.' appears twice with different dates (2024-09-12 and 2024-08-23). This is likely a duplicate submission and was counted only once for scoring purposes.
• DUPLICATE REVIEW DETECTED: The review 'I called Prima to install some new water lines and a hose bib because they were close to my home...' appears twice with dates 2022-06-10 and 2022-06-01. Counted only once for scoring.
• BLANK REVIEWS: Six reviews contain no text (only a rating of 5.0). These were excluded from dimension scoring as they provide no usable evidence per scoring rules.
• RECENCY NOTE: The review corpus spans from 2009 to 2024. Reviews older than 12 months (pre-November 2023) make up the large majority of the dataset. The most recent reviews (2024) are generally positive, but the older negative patterns — particularly around pricing transparency and phone staff attitude — should not be dismissed as resolved without more recent corroborating evidence.
• RECURRING NEGATIVE PATTERN — PHONE/OFFICE STAFF: At least 6–7 independent reviews across different years (2014, 2015, 2017, 2018, 2023) specifically cite rude, dismissive, or unhelpful behavior from a female office staff member. This is a consistent and credible pattern that suppresses the professionalism score.
• RECURRING NEGATIVE PATTERN — PRICING TRANSPARENCY: At least 5 independent reviews cite bills that significantly exceeded initial quotes, charges for service calls where no work was performed, or rates described as unexpectedly high. This is a credible pattern suppressing the pricing score.
• POTENTIAL FAKE/THIN REVIEWS: Several 5-star reviews contain only 1–2 generic sentences with no specifics (e.g., 'Great guys and great company', 'Did a great and fast job', 'Prima is excellent. Knowledgeable, professional, great service and work done.'). While not conclusive, these add limited evidentiary value and were weighted conservatively.

This WW Score is based on a large and diverse review corpus spanning over a decade, with high mention counts across all four dimensions, making it statistically reliable — however, users should note that recurring negative patterns around office staff conduct and pricing transparency are credible and consistent enough to be treated as genuine risk factors rather than outliers.

Ocean Plumbing earns strong marks across all four dimensions, with professionalism and experience being the most consistently praised attributes across a large volume of reviews spanning over a decade. The majority of customers highlight courteous, knowledgeable technicians who communicate clearly and leave job sites clean. Pricing is generally regarded as fair or better than competitors, though one notable complaint about a $100 parts markup on a $10 hose bib and one complaint about $1,340 charged for minimal work introduce meaningful concern about pricing consistency. Project completion is largely positive, but is tempered by one serious complaint about abandoned work and unresolved issues across two properties, and one instance of a no-call/no-show, which are significant red flags that prevent a higher score in that dimension.

• 7 reviews contain no text content — only a star rating. These were excluded from dimension scoring as they provide no usable data.
• 2 reviews are labeled 'unknown' with no text. These were excluded entirely.
• Review dated 2023-06-10 (1-star) describes a serious project completion failure: $1,340 charged for wax rings and drain cleaning with the original problem unresolved across two properties, and the plumber allegedly refused to return to make it right. This is a significant project completion and professionalism red flag.
• Review dated 2017-06-18 (1-star) describes contract non-compliance: green board installed instead of contracted hardiboard, crooked tile work, and bent pipes. This is a workmanship and project completion concern.
• Review dated 2022-01-08 (1-star) describes a no-call/no-show situation, directly impacting professionalism score.
• Review dated 2025-05-10 (3-star) flags a $100 parts charge for a $10 hose bib, suggesting potential parts markup transparency issues.
• Multiple technician names appear across reviews (James, Ricardo, Jordan, Justin, Oscar, Matt, John) suggesting this is a multi-technician operation. Quality and pricing consistency may vary by technician.
• The majority of reviews are older than 12 months. Only 6 reviews are dated within the past 12 months (mid-2024 to mid-2025), limiting recency confidence. Older reviews from 2008–2021 were given reduced weight.
• Several 5-star reviews use generic praise with limited specifics (e.g., 'Fast and courteous staff! Highly recommend!' and 'Best plumber!'). While not conclusive, a small subset of reviews may reflect low-detail or potentially inflated ratings.

This WW Score is based on a substantial volume of reviews (70 total, 63 with usable data) spanning over 15 years, giving it HIGH overall confidence, but consumers should note that only 6 reviews are from the past 12 months, there are three distinct negative reviews describing serious failures in pricing transparency and project completion, and technician quality may vary across the multi-person team.

Plumbing and Heating Specialist earns strong marks across all four dimensions, with professionalism and experience being consistent highlights across dozens of reviews spanning nearly a decade. Pricing is frequently praised as competitive, transparent, and fair — with multiple reviewers noting they received the lowest bid among several quotes, and several instances of no-charge service for minor fixes. However, project completion is the weakest dimension: four separate negative reviews (1–2 star ratings) describe serious failures including a no-show with no callback, an unresolved AC repair with no follow-up, an incomplete Groupon service, and an abandoned gas line installation with a full voicemail box — these are significant reliability red flags that meaningfully drag down the completion score. The volume of positive reviews is high, but the pattern of negative reviews consistently points to communication breakdowns and follow-through failures, suggesting systemic issues under pressure or high workload periods.

• COMPLETION CONCERN: Four reviews explicitly describe abandoned or incomplete work, no-shows, or failure to return calls — a recurring pattern that suggests intermittent but serious reliability issues.
• RECENCY NOTE: The single most recent negative review (2021-07-30) describes an unresolved $600 AC repair with no callback, which is particularly concerning as it is more recent than most positive reviews.
• ONE REVIEW FLAGGED AS IRRELEVANT: The review dated 2016-12-17 appears to be a review of Beacon Plumbing, not Plumbing and Heating Specialist. It was excluded from scoring as it does not pertain to this contractor.
• RECENCY SKEW: The majority of reviews are from 2015–2022, with only one review from the past 12 months (2024-06-04). The current reliability of this contractor cannot be fully assessed from recent data alone.
• FAKE REVIEW CHECK: No strong indicators of fake reviews detected. Reviews contain specific names, job details, and varied language. However, the volume of highly enthusiastic 5-star reviews with no negatives in early years warrants mild caution.
• PRICING TRANSPARENCY CONCERN: One reviewer (2021-04-14) noted a non-itemized quote range of $2,700–$3,500 and received no follow-up after requesting specifics, suggesting inconsistent quoting practices.

This WW Score is based on 50 reviews with high mention counts across all dimensions and should be treated as moderately reliable, but the recurring pattern of no-shows and abandoned work in negative reviews introduces meaningful uncertainty about project completion consistency.
