Find Nearby Plumbers In Honolulu, Hawaii

Russell's demonstrates strong performance across all measured dimensions with consistent positive feedback. Professionalism is well-supported by mentions of promptness, communication, knowledge, and courteous service. Project completion is evidenced by timely job delivery and adherence to quoted prices across multiple complex plumbing jobs. Technical expertise is reflected in problem-solving ability and quality workmanship on complicated drain and pipe work. Pricing feedback is limited but positive where mentioned. The primary limitation is the small sample size (5 reviews) and significant age of most reviews (3 of 5 are from 2011–2014), which reduces confidence in current performance reliability.

• Review recency concern: 3 of 5 reviews are over 10 years old (2011–2014). Only 2 reviews are from the past decade (2021, 2012). Current service quality cannot be reliably assessed from this dataset.
• Small sample size: Only 5 total reviews limits statistical confidence. Recommend collecting additional recent reviews before making high-confidence decisions.
• Pricing dimension underrepresented: Only 2 mentions of pricing. One review notes 'slow responsiveness' which slightly tempers the otherwise perfect ratings.

This WW Score should be treated with caution due to the small sample size and predominantly outdated reviews; while historical performance appears strong, current reliability cannot be confidently assessed without more recent customer feedback.

Harada Plumbing demonstrates strong professionalism across multiple recent reviews, with consistent praise for friendly, polite, and prompt service. Project completion is solid with evidence of jobs finished properly and callbacks honored. Pricing receives mixed signals—two reviews note competitive or fair pricing, but one explicitly states prices felt 'a little high,' suggesting value perception varies. Technical skill is evidenced by successful installations and problem-solving, though limited explicit detail on workmanship complexity. The score is anchored by strong professionalism and completion metrics, tempered by modest sample size and limited pricing consensus.

• Four of five reviews are 5-star ratings with generic praise language ('Amazing service,' 'Great local company'), which could suggest selection bias or review curation, though the 4-star review provides balancing detail.
• One review (2019-10-08) is significantly older than the others (5 years old); recent reviews (2024) dominate the dataset and are more reliable indicators of current performance.
• Pricing dimension based on only 2 mentions with conflicting signals—one positive comparison to competitors, one stating price was 'a little high'—limiting confidence in pricing score.
• Experience dimension has only 2 mentions; limited explicit detail on technical complexity or specialized skill demonstration.

This WW Score of 88.2 should be treated with moderate confidence due to the small sample size (5 reviews) and heavy weighting toward recent 5-star ratings; the score is reliable for professionalism and project completion but less certain for pricing and experience dimensions.

Mark demonstrates strong professionalism across all three reviews, with consistent praise for his quiet demeanor, responsiveness, and reliability. His pricing is explicitly noted as fair and reasonable in two reviews, with customers emphasizing good value. Project completion is solid—he addresses multiple issues comprehensively, fixes problems left by other contractors, and follows through on callbacks. Technical expertise is evident across all reviews, with specific mention of his knowledge of Hawaii homes, gas lines, water heater installation, and diagnostic skills. However, the sample size is small (3 reviews) and the most recent substantive review is from 2024, while two others are significantly older (2019 and 2011), limiting confidence in current performance.

• Very small sample size (n=3) limits statistical reliability; recommend collecting more recent reviews before making major decisions
• Two reviews are over a decade old (2011, 2019); only one recent review from 2024 provides current performance data
• First review contains informal language and personal anecdotes (lilikoi jam, plants) that, while charming, reduce its professional assessment value; however, it does provide substantive technical detail about work quality
• No negative reviews present; while all positive feedback is encouraging, absence of critical feedback may not reflect full picture of contractor performance

This score should be treated with caution due to the very small sample size (3 reviews) and significant age gap between reviews. The 2024 review provides some current validation, but a minimum of 8-10 recent reviews would be needed to establish high confidence in Mark's current performance and reliability.

David and his crew receive consistently strong praise across all four dimensions, with professionalism being the most frequently and specifically cited strength — reviewers highlight punctuality, communication, cleanliness, and attitude in multiple independent reviews. Project completion scores well, with several reviewers noting jobs finished on time, efficiently, and to a high standard across diverse project types including bathroom renovations, kitchen remodels, window replacements, and plumbing repairs. Experience is supported by references to quality workmanship, attention to detail, and the ability to handle both minor repairs and major renovations. Pricing is noted positively in three reviews, with one reviewer specifically surprised by the fairness of the cost and another describing the price as reasonable, though the sample is smaller. The overall picture is of a reliable, skilled, and personable contractor, though the total review count of 6 limits the statistical confidence of these scores.

• Low total review count (6 reviews) — scores should be treated as directionally useful but not statistically robust.
• All 6 reviews are 5-star ratings with no negative or mixed feedback, which warrants mild caution. However, most reviews contain specific details (project types, timing, pricing interactions) that reduce the likelihood of fabrication.
• One review (2024-04-04) reads in a more formal, promotional tone and lacks the personal specificity of other reviews — it may be from a business referral partner rather than a direct end customer, which could introduce slight bias.
• No reviews mention any negative experiences, delays, disputes, or areas for improvement — while this may reflect genuine quality, it limits the ability to assess how David handles problems or setbacks.
• All reviews fall within the past 12 months (January–August 2024), which is a positive recency signal and means no downweighting for age is required.

This WW Score is moderately reliable given the small but recent and mostly specific review set — it should be treated as a promising early signal of quality rather than a fully validated track record.

A-1 Budget Plumbing earns strong marks for professionalism, with the vast majority of substantive reviews praising courteous, communicative, and punctual technicians across many years and many different plumbers. Pricing is a genuine mixed bag: numerous reviewers explicitly praise the company as affordable and fair, while a meaningful minority report sticker shock — including a $1,400 charge after an $850–$900 high-end estimate, a $457 dripping showerhead repair, and a $1,700 sump pump replacement — pulling the pricing score down considerably. Project completion is solid overall but is weighed down by recurring issues: at least one no-show with no callback, a case where a plumber left a broken snake in a pipe, a misdiagnosed leak that required a second visit the customer had to pay for, a toilet repair that caused a flood, and a drain problem that recurred within a week with no warranty honored. Experience scores well on average — many reviewers describe skilled, knowledgeable technicians who solved difficult problems — but is tempered by several documented cases of misdiagnosis, incomplete work, and at least one instance where a non-plumber fixed what two A-1 plumbers said required a full toilet replacement. The review corpus spans from 2010 to 2025, and recent reviews (2024–2025) trend more positively, suggesting the company may have improved over time.

• 27 reviews contain no text whatsoever (blank or 'unknown') and were excluded from dimension scoring; they contribute only to total review count.
• A cluster of reviews dated 2025-05-09 and 2025-06-08 share identical timestamps across multiple reviews, which may indicate batch imports or platform aggregation rather than organic individual submissions — treat this cluster with mild caution.
• All star ratings are 4 or 5 stars with the exception of clearly negative reviews; there is no 2-star middle ground in recent reviews, which is a mild fake-review pattern signal, though the presence of detailed negative reviews across the full corpus reduces this concern significantly.
• Several reviews from 2013–2017 are extremely brief ('unknown', 'good', 'see above', 'Re-routed main line') and provide no scorable data.
• Pricing complaints are concentrated but specific and credible (exact dollar amounts cited), and are not offset by the volume of positive pricing mentions alone — the pricing score reflects genuine inconsistency rather than uniformly fair rates.
• One review (2022-03-23) alleges a flooded home caused by an overtightened toilet handle installed by A-1, with no management response or callback — a serious liability flag.
• One review (2012-05-06) alleges a plumber's snake broke off inside a pipe and was not disclosed or remediated — a significant workmanship and ethics concern.
• Recency note: The majority of detailed, scorable reviews are from 2021–2025, which is a positive signal. Reviews from 2010–2017 skew more mixed and are down-weighted accordingly.

This WW Score is based on a large and diverse review corpus spanning 15 years with HIGH confidence across all four dimensions, and should be considered a reliable representation of this contractor's overall performance, with the caveat that pricing consistency and project completion reliability remain genuine areas of risk that prospective customers should discuss explicitly before hiring.

The majority of reviews — particularly those from 2025 — reflect a consistently professional and skilled team at Olson Superior Plumbing, with multiple technicians (Logan, Francisco, Richie, Aaron, Thomas, Marcos, Elliott) praised for punctuality, courtesy, and technical competence. However, two significant 1-star reviews from 2025 describe serious failures: a technician arriving at the wrong time and refusing to waive a service fee after offering no real help, and a separate incident where a quoted project was doubled in price on the day of work after two failed appointment attempts. Pricing confidence is dragged down by these incidents alongside older Optimal Plumbing reviews describing a contractor who billed more than 2X the written quote and threatened a Mechanic's Lien. Project completion scores are similarly tempered by the abandoned/rescheduled job and the incorrect parts installation described in negative reviews. Experience scores are generally strong based on detailed positive accounts of skilled diagnostics and quality workmanship, but the poor soldering and incorrect drain installation in one Optimal Plumbing review prevent a higher score.

• MIXED CONTRACTOR DATA: This review set appears to contain reviews for at least two distinct businesses — 'Olson Superior Plumbing' and 'Optimal Plumbing LLC' (Ron/Ronnell). These are different companies and should not be scored together. The WW Score has been calculated across all reviews as submitted, but this significantly reduces reliability.
• BLANK REVIEWS: 4 reviews contained no text (only a star rating). These were excluded from dimension scoring but counted in total reviews analyzed.
• RECENCY CONCERN — OPTIMAL PLUMBING: Most Optimal Plumbing reviews are 3–9 years old (2015–2024), with the most critical negative review dating to 2015. These older reviews carry reduced weight but still meaningfully impact pricing and project completion scores.
• DRIVING COMPLAINTS: Two 1-star reviews (2016, 2021) describe dangerous driving by company vehicles and inability to reach anyone by phone. These reflect on professionalism and responsiveness and were factored into the professionalism score.
• PRICING RED FLAG — OPTIMAL PLUMBING: One detailed 1-star review describes a final bill more than 2X the written quote, threats of a Mechanic's Lien, and refusal to communicate. This is a serious pricing and professionalism concern.
• PRICING RED FLAG — OLSON SUPERIOR: One 1-star review describes a $1,800 quote for a job another plumber completed for approximately $360, plus a disputed $95 service fee. This suggests potential price gouging on at least one occasion.
• PROJECT FAILURE — OLSON SUPERIOR: One detailed 1-star review describes two failed appointment attempts, a technician doubling the quoted price on-site, and disrespectful behavior toward management in front of the customer. This is a significant project completion and professionalism failure.
• POSSIBLE GENERIC REVIEWS: Several short 5-star reviews ('Excellent team!', 'Very informative and personable', 'Great service!') lack specific detail. While not conclusive evidence of fake reviews, they add limited scoring value and were weighted conservatively.

This WW Score carries moderate-to-high reliability for Olson Superior Plumbing's recent (2025) performance, but is materially compromised by the inclusion of reviews for a separate business (Optimal Plumbing LLC), several blank reviews, and a small number of serious negative experiences that reveal real risks around pricing transparency and project management consistency.
