Find Nearby Plumbers In Livermore, California

Viking Plumbing demonstrates strong professionalism with consistently punctual service, friendly technicians, and responsive communication across 127 mentions. Technical expertise and problem-solving ability are well-documented across 95 mentions, with plumbers frequently praised for knowledge and skill. Project completion is solid with 89 mentions showing jobs finished on time and callbacks honored, though a few notable failures (sewer line misdiagnosis, repeated clogs, no-shows) create some concern. Pricing emerges as the weakest dimension (71.0) with 48 mentions revealing complaints about lack of transparency, unexpected cost increases, and prices perceived as high relative to work performed. Recent reviews (past 12 months) are predominantly 5-star with some repetitive phrasing, though older reviews provide balanced perspective.

• FAKE REVIEW PATTERN DETECTED: Multiple identical reviews appear verbatim across different dates (e.g., 'Manny was so friendly and efficient! He cleared 2 drains and they're working beautifully. I will definitely be using Viking for future plumbing needs!' appears on 2025-06-08 and 2025-06-05; 'You guys always do an awesome job!' on 2025-06-08 and 2025-06-05; 'Always great service. Very professional office and plumbers. Thanks' on 2025-06-08 and 2025-06-05; 'Jesse and Justice were amazing!...' on 2025-06-07 and 2025-06-04). This suggests potential review manipulation or bot-generated content.
• RECENCY BIAS: Approximately 40% of reviews are from June 2025 (very recent), with a cluster of suspiciously similar 5-star reviews in early June 2025. Older reviews (2010-2020) provide more balanced feedback including legitimate complaints.
• CRITICAL FAILURES: Three 1-star reviews document serious issues: (1) Sewer line misdiagnosis costing customer $7,000+ in remediation; (2) Urinal valve rebuilt 5 times, still leaked; (3) Multiple no-shows and scheduling failures. These are not minor issues.
• PRICING TRANSPARENCY PROBLEM: Multiple reviews (2020, 2013, 2011) cite unexpected cost increases, lack of upfront pricing disclosure, and bills significantly exceeding quotes. One customer reported nearly 100% increase from quoted price ($618 to $1,100).
• OWNERSHIP/MANAGEMENT CHANGE: Reviews note company was purchased by different ownership, with service quality reportedly declining post-acquisition (2023 reviews show scheduling and follow-up failures).
• INCONSISTENT QUALITY: Wide variance in outcomes—some jobs completed perfectly same-day, others require multiple callbacks or fail entirely. Suggests inconsistent technician quality or training.

This WW Score of 78.2 should be treated with MODERATE-TO-HIGH caution due to suspected review manipulation in the most recent data (June 2025 cluster of identical reviews). The HIGH confidence rating is supported by large mention counts across all dimensions and consistency in older reviews, but the recent fake review pattern undermines the overall trustworthiness of the current score. Pricing remains a genuine weakness with documented evidence of transparency issues. Recommend weighting older reviews (2015-2022) more heavily and requesting itemized quotes in writing before engaging services.

General Plumbing Supply demonstrates strong technical expertise and product knowledge, with consistently high marks for staff experience and knowledgeable assistance. However, professionalism is significantly undermined by numerous reports of rude, dismissive, and unhelpful customer service, particularly toward DIY customers and those unfamiliar with plumbing. Pricing is generally viewed as fair to competitive, though some perceive it as premium. Project completion shows mixed results with delivery delays and order fulfillment issues reported in several cases. The company excels when individual staff members (Luis, Carlos, Jon, Ellen, etc.) provide exceptional service, but inconsistency across locations and personnel is a major concern.

• SIGNIFICANT PROFESSIONALISM VARIANCE: Multiple reviews (at least 15+) describe rude, dismissive, or unwelcoming staff behavior, particularly toward non-professional/DIY customers. This is a systemic issue affecting multiple locations and time periods.
• LOCATION-BASED INCONSISTENCY: American Canyon location receives disproportionately negative reviews for customer service, while Brentwood and Walnut Creek locations receive more positive feedback. Service quality appears highly dependent on which staff member assists the customer.
• DELIVERY AND ORDER FULFILLMENT ISSUES: Several reviews (2018-2021) report significant delays, wrong items shipped, incomplete orders, and poor communication regarding delivery timelines. One review describes a 3.5-week estimate that became 3.5 months.
• STAFF ATTITUDE TOWARD DIY CUSTOMERS: Recurring pattern of staff deflecting DIY customers to Home Depot or expressing disdain for non-professional customers, suggesting possible business model bias against retail customers.
• POTENTIAL FAKE REVIEW PATTERN: Cluster of 5-star reviews on 2022-06-10 and 2023-06-10 with minimal detail (e.g., 'Great service', 'Awesome staff!', 'Knowledge helps') alongside detailed negative reviews suggests possible review manipulation. However, many detailed positive reviews exist, so confidence in fake review detection is LIMITED.
• RECENCY NOTE: Most recent reviews (2024-2025) show improved sentiment with fewer extreme negatives, suggesting possible recent management changes or staff training improvements.

This WW Score of 76.8 is reliable at HIGH confidence due to 227 reviews with substantial data across all dimensions, but the score masks significant operational inconsistency: the company excels in product expertise and selection but struggles with customer service delivery and professionalism, particularly toward non-professional customers. Prospective customers should expect variable experiences depending on location and staff member encountered.

Brasso's Plumbing receives strong praise across most dimensions, with recurring themes of responsive communication, on-time arrivals, and efficient crew-based work completing large jobs like full re-pipes in a single day. Pricing is frequently cited as competitive and transparent, with multiple reviewers noting Brasso's quotes came in significantly lower than competitors. However, two notable negative reviews meaningfully drag down the scores: one describes a misdiagnosis that would have led to costly unnecessary work, and another documents a prolonged period of ignored callbacks before eventual resolution. These incidents introduce real concerns about diagnostic accuracy and owner responsiveness that prevent top-tier scores. The majority of reviews are older than 12 months, with most clustering between 2011 and 2018, which limits confidence in how well these scores reflect current performance.

• RECENCY WARNING: All 19 reviews are dated between 2005 and 2018. The most recent review is from December 2018 — over 6 years ago. This score may not reflect current business quality or practices.
• NEGATIVE INCIDENT — MISDIAGNOSIS: One reviewer (2017) reports Brasso's recommended an expensive and incorrect fix (demolishing walls and floors for a slab drain) when the actual leak was under the dishwasher. A second company identified the correct issue. This is a meaningful quality-of-work concern.
• NEGATIVE INCIDENT — RESPONSIVENESS FAILURE: One reviewer (2015) reports the owner Brad failed to show up for a scheduled appointment and stopped returning calls entirely before eventually resolving the issue. This contradicts the otherwise positive responsiveness pattern.
• SECOND OPINION CONCERN: One reviewer (2018) explicitly warns readers to get a second opinion after Brasso's quoted $1,500 and an 8-hour job requiring lawn excavation, while another plumber fixed the same issue in 2 hours without digging.
• GENERIC PRAISE PATTERN: Several older reviews (2005–2011) contain limited specifics and read as brief endorsements without detail. These were included but weighted conservatively due to age and low specificity.
• REVIEW AGE DISTRIBUTION: Approximately 12 of 19 reviews are from 2015 or earlier, meaning the bulk of the data is 9+ years old. Scores should be treated as historical rather than current indicators.

This WW Score carries moderate-to-high structural reliability given 19 reviews with usable data across all four dimensions, but its real-world trustworthiness is significantly limited by the age of the review set — all reviews predate 2019 — and by two substantive negative incidents involving misdiagnosis and owner unresponsiveness that introduce meaningful doubt about consistency.

This aggregated review set spans many years and appears to cover multiple distinct businesses operating under similar 'My Plumber' branding across different cities and states, which significantly complicates scoring. The majority of reviews are strongly positive, praising responsiveness, friendliness, technical knowledge, and fair pricing — with many customers becoming repeat clients. However, a meaningful minority of negative reviews (approximately 35–40 reviews) describe serious failures including no-shows, unreturned calls, warranty non-compliance, work left incomplete after payment, billing disputes, property damage, and in at least one case alleged threats of violence. Pricing feedback is mixed: many reviewers praise affordability and transparency, while others report unexpected price increases, bait-and-switch billing, and feeling overcharged. Project completion is the most concerning dimension, with multiple reviews describing abandoned jobs, callbacks ignored, and work that failed shortly after completion.

• MULTI-ENTITY CONCERN: Reviews appear to cover multiple unrelated businesses operating under 'My Plumber,' 'My Plumber Inc.,' 'Clog Pro,' 'Precision Plumber Buckeye,' '1 Buckeye Plumbing,' and other names. Scores should not be attributed to any single contractor without filtering by specific business identity.
• FAKE REVIEW SUSPICION: Several reviews from dates 2024-12-11 and 2025-03-11 use nearly identical generic phrasing ('arrived fast,' 'skilled,' 'professional,' 'handled the repair seamlessly') with no specific technician names, job details, or unique identifiers. These are flagged as potentially inauthentic.
• RECENCY NOTE: Reviews span from 2006 to 2025. Reviews older than 3 years (pre-2022) were given reduced weight. The most recent 12 months (mid-2024 to mid-2025) show a continued mix of strong positives and some negatives.
• SERIOUS NEGATIVE INCIDENTS: At least one review describes alleged threats of violence by an owner (Steve Martin, Arizona). At least two reviews describe property damage (cracked tile, broken bathtub stopper) with no remediation. At least three reviews describe warranty non-compliance and abandoned work after payment.
• NO-SHOW AND RESPONSIVENESS FAILURES: Approximately 12–15 reviews explicitly describe missed appointments, unreturned calls, or complete failure to follow through on scheduled work — a recurring pattern across multiple named technicians and locations.
• BLANK REVIEWS: Approximately 55–60 reviews contain no text, only a star rating. These were excluded from dimension scoring but counted in total review volume.
• SCORE CONSERVATISM APPLIED: Due to the multi-entity nature of this dataset, the high volume of serious negative reviews, and fake review suspicion, all dimension scores were held conservative per Rule 7.

This WW Score carries HIGH data confidence due to the large review volume, but LOW entity reliability — the dataset almost certainly aggregates reviews for multiple distinct businesses, making this score unsuitable for evaluating any single contractor without first filtering reviews by specific business name, location, and technician.

Amigo Rooter & Plumbing has a large and generally positive review base, with the majority of customers praising same-day responsiveness, punctuality, friendly technicians, and fair pricing compared to larger chain companies. Recurring technicians like Junior, Ely, Aiden, and Nelson are frequently cited by name for professionalism and thoroughness. However, a meaningful cluster of 1-star reviews — spanning multiple years — raises serious concerns: allegations include upselling, warranty refusal, no-shows, failure to fix problems on the first visit, broken components attributed to technician error, and two separate theft allegations involving employees. These negative reviews are specific, detailed, and credible enough to materially reduce scores across all dimensions. The score reflects a company with genuine strengths but a documented pattern of service failures that cannot be dismissed.

• THEFT ALLEGATIONS: Two separate 1-star reviews (Sept 2018) allege that technicians stole jewelry from inside customers' homes. These are serious, specific, and independently corroborated allegations that significantly impact trustworthiness.
• REPEATED NO-SHOW / UNRESPONSIVENESS PATTERN: Multiple reviews (2017, 2019, 2020) describe technicians failing to show up within promised windows, not returning calls or texts, and failing to follow through on written quotes or part orders.
• WARRANTY / CALLBACK REFUSAL: Several reviews describe the company refusing to honor their own work, denying responsibility for damage caused by technicians, or requiring additional charges to fix problems they created.
• UPSELLING / BAIT-AND-SWITCH CONCERNS: Multiple 1-star reviews allege price changes after arrival, attempts to sell unnecessary services, and technicians misrepresenting the scope of work to inflate charges.
• INCOMPLETE WORK / RECURRING FAILURES: At least 3 reviews describe the same plumbing issue recurring shortly after service, with the company being unresponsive or unwilling to return without additional fees.
• BLANK REVIEWS: 15 reviews contained no text — only a 5-star rating. These were excluded from dimension scoring as they provide no usable data. Their presence slightly inflates the raw star average.
• RECENCY NOTE: The majority of detailed positive reviews are from 2025 and 2024, which is encouraging. However, the negative reviews span from 2013 through 2021, suggesting the issues are not isolated to a single period.
• POSSIBLE GEOGRAPHIC INCONSISTENCY: Some reviews reference Livermore/Hayward/California locations while others reference Goodyear/Avondale/Arizona. This may indicate the business operates in multiple markets or that some reviews may belong to a different entity under the same name — scores should be interpreted with this ambiguity in mind.
• NO FAKE REVIEW PATTERN DETECTED: Positive reviews are generally specific, name individual technicians, and describe distinct job types. No strong evidence of coordinated fake reviews, though the volume of blank 5-star ratings warrants mild caution.

This WW Score is based on a large review set (125 reviews) with high mention counts across all four dimensions, giving it statistical weight — however, the score should be treated with caution due to credible and recurring allegations of theft, upselling, warranty refusal, and no-shows that represent a meaningful minority of the review base and cannot be dismissed as outliers.

The majority of reviews praise this contractor's responsiveness, punctuality, and friendly demeanor, with many customers reporting same-day or next-day service and technicians arriving on time. However, a meaningful minority of negative reviews — spanning multiple years — raise serious concerns about pricing transparency, including inflated hours, surprise charges beyond quoted amounts, and misleading claims about parts availability. Project completion is generally strong, with most jobs described as finished promptly and thoroughly, but several reviews document abandoned work, unresolved issues after payment, and a failure to stand behind completed work when problems emerged later. Experience scores are solid overall, with multiple reviewers specifically praising technical knowledge and problem-solving, though at least two reviews describe technicians who appeared unskilled or unable to diagnose basic issues correctly.

• Several reviews from 2024–2025 are extremely brief, generic, or contain no review text at all (only a star rating), which reduces their evidentiary value and raises mild concern about authenticity.
• Two reviews appear to be near-identical duplicates: the review praising 'Adam and Israel' with 'Esme the dispatcher' appears verbatim in both a 2017 and a 2016 entry — this is a strong indicator of a duplicated or potentially manipulated review.
• The review dated 2021-04-06 reads like promotional or AI-generated marketing copy rather than a genuine customer experience, with no specific job details and unusual phrasing. Confidence in this review is low.
• Multiple negative reviews cite pricing dishonesty: inflated hours (2021), surprise charges beyond quote (2016, 2019), misleading parts claims (2018), and a 60% quote increase after initial contact (2023). This pattern is consistent and credible across independent reviewers.
• One review (2020-10-08) describes a major post-job leak causing floor damage and the company refusing to respond or stand behind their work — a serious project completion and integrity flag.
• One review (2023-11-02) describes a $250 charge for unresolved work, with the actual fix later performed by a competitor — a direct project completion failure.
• One review (2023-03-31) describes a last-minute cancellation with no backup plan, resulting in a lost appointment — a professionalism and reliability concern.
• One review (2016-03-25) describes a no-call, no-show appointment — a reliability flag.
• One review (2011-05-12) describes significant punctuality failures and poor communication from the owner — though this is older, the pattern recurs in more recent reviews.
• Review corpus spans from 2011 to 2025. Reviews older than 3 years (pre-2022) have been given reduced weight in scoring. The business appears to have multiple staff members and possibly operates across different service areas, which may explain some inconsistency in quality.

This WW Score is based on a large review set (109 reviews) with HIGH confidence across all four dimensions, but the score should be interpreted cautiously due to a recurring and credible pattern of pricing transparency complaints, at least one serious post-job abandonment incident, suspected duplicate reviews, and several content-free star-only submissions that inflate the apparent rating without providing usable evidence.
