Find Nearby Plumbers In Vallejo, California

Integrity Plumbing demonstrates strong overall performance across all dimensions, with particularly high marks for professionalism (87.5) driven by consistent praise for punctuality, communication, and courteous staff. Pricing scores well (82.0) with many customers noting fair, transparent, and competitive rates. Project completion (85.5) reflects reliable follow-through, though a small number of reviews mention delayed callbacks or incomplete follow-up. Technical expertise (83.0) is consistently praised, with customers highlighting knowledgeable technicians and thorough diagnostics. The company's name genuinely reflects its operational values in the majority of reviews.

• FAKE REVIEW PATTERN DETECTED: Reviews dated 2025-06-08, 2025-06-05, and 2025-06-03 contain identical text (long, detailed narrative about managing renovation projects, mentioning Emily, James, Josh, Steve, Lyle by name). This repetition across three consecutive dates is highly suspicious and suggests potential review manipulation.
• EMPTY REVIEWS: 18 reviews contain only a 5.0 rating with no text content. While not necessarily fake, these provide no substantive data and inflate review count without evidence.
• RECENCY BIAS: Approximately 60% of reviews are from 2024-2025 (past 12 months), with a sharp increase in volume in recent months. Earlier reviews (2006-2020) show more varied ratings (including 1-3 star reviews), while recent reviews are overwhelmingly 5-star. This pattern warrants caution.
• NEGATIVE REVIEWS CONCENTRATED IN PAST: Most 1-star and 2-star reviews are from 2013-2022. Recent negative reviews (2024-2025) are rare, which could indicate either genuine improvement or selective review removal/suppression.
• MULTIPLE BUSINESS LOCATIONS/OWNERS: Reviews reference different owners/technicians across different regions (Dave, James, Toby, Marc, Sean, etc.) and locations (Rancho Santa Margarita, Vallejo, Omaha, Utah, Brentwood, etc.), suggesting either multiple franchises under one name or significant data mixing. This complicates reliability assessment.
• INCONSISTENT COMPANY IDENTITY: Some reviews reference 'Integrity Plumbing' as a single-owner operation (Dave, James, Toby), while others describe it as a larger company with multiple crews. Geographic and personnel inconsistencies suggest these may be different companies with the same name.

While the WW Score of 84.2 reflects genuinely positive feedback across most dimensions, the reliability is MODERATE-TO-HIGH rather than fully HIGH due to: (1) suspicious identical reviews in June 2025 suggesting potential manipulation, (2) 18 empty 5-star reviews providing no evidence, (3) dramatic recency bias with 60% of reviews from past 12 months and nearly all recent reviews being 5-star, and (4) apparent mixing of multiple businesses/locations under the same name. The score is most trustworthy for recent service quality (2024-2025) but should be viewed with caution regarding historical consistency. Customers should verify they are contacting the correct location/owner before booking.

Sewer Connection demonstrates strong overall performance with a WW Score of 82.3, driven by consistently high marks across all four dimensions. The company excels in experience and pricing, with customers frequently praising skilled workmanship, competitive rates, and fair pricing practices. Professionalism is solid, with many reviews highlighting responsive communication, punctuality, and courteous staff. However, project completion shows the lowest score due to a significant pattern of no-shows, scheduling delays, and follow-up failures documented in older reviews (2011-2016), though recent reviews (2019-2024) show marked improvement. The company appears to have undergone management changes around 2019-2020 that substantially improved reliability and customer service.

• CRITICAL RECENCY ISSUE: Reviews from 2011-2018 contain numerous complaints about no-shows, scheduling failures, and poor follow-up. Reviews from 2019 onward are overwhelmingly positive (5-star ratings). This suggests significant operational changes or management transition around 2019.
• One review (2022-12-15) explicitly states 'under new ownership' and criticizes bait-and-switch pricing tactics with hidden 'unforeseen fees.' However, a follow-up review (2022-11-18) from the same period acknowledges management change and improved transparency.
• Negative reviews cluster in 2011-2018 period with consistent themes: no-shows, unresponsiveness, scheduling delays, and poor communication. These represent approximately 15 of 89 reviews.
• Recent reviews (2019-2024, approximately 60+ reviews) are predominantly 5-star with specific, detailed praise. No pattern of fake reviews detected in recent cohort—praise is specific and varied (different crew members named, different project types, different locations).
• One 2019 review (rating 3.0) mentions poor phone customer service from office staff despite good technician work, suggesting inconsistent office-side professionalism.
• Project completion score is conservative due to documented historical no-show and delay issues, despite strong recent performance. Confidence remains HIGH due to large mention count (71), but score reflects the full historical record.

This WW Score of 82.3 is reliable for evaluating current performance (2019-2024), but customers should be aware that the company had serious operational and reliability issues prior to approximately 2019. Recent reviews demonstrate substantial improvement in all dimensions, particularly project completion and communication. If considering this contractor, prioritize recent reviews and verify current management/ownership status.

Honrath & Stacey demonstrates strong overall performance with consistent professionalism, fair pricing, and solid technical expertise across plumbing and HVAC services. The company excels in responsiveness, punctuality, and honest communication, with many customers praising their willingness to recommend cost-effective solutions rather than unnecessary replacements. However, project completion reliability is tempered by several documented failures in follow-through, accountability, and quality control on complex jobs, particularly involving assistant Jordan. Critical incidents involving gas safety violations, incomplete work, and defensive responses to legitimate complaints significantly impact trust despite the majority of positive reviews.

• CRITICAL SAFETY ISSUE: One review (2023-12-12) documents a gas leak caused by improper threading of a furnace part, with the owner allegedly dismissive and argumentative when confronted. This is a serious liability concern.
• ACCOUNTABILITY PATTERN: Multiple reviews (2021-09-12, 2022-09-19, 2023-12-12) describe owner Joey becoming defensive, denying responsibility, or providing inconsistent explanations when errors occur. This pattern suggests systemic accountability issues.
• ASSISTANT QUALITY CONTROL: Reviews from 2021-09-12 and 2021-10-18 indicate assistant Jordan has caused multiple failures (backwards cartridge installation, broken water heater door, incompetent work). Supervision appears inadequate.
• INCOMPLETE WORK: Review from 2022-11-06 documents unfinished sump pump integration and failure to follow up on promised water heater service despite multiple reminders.
• PRICING INCONSISTENCY: Review from 2022-06-20 reports significant overcharging ($660 for under 1 hour work) with partial refund only after complaint. Review from 2016-02-16 vaguely alleges 'rip off' pricing for emergency service.
• COMMUNICATION FAILURES: Review from 2022-09-19 documents multiple contradictory explanations, wrong phone number written down, and no offer to remedy the situation after missing a hotel emergency appointment.
• RECENCY NOTE: Most reviews are from 2018-2024, with strong recent positive reviews (2024) but also critical negative reviews from 2023 and 2022. Recent pattern shows both excellence and serious failures.
• POTENTIAL FAKE REVIEW PATTERN: Two reviews (2021-10-18 at 15:12:56 and 12:09:05) are identical word-for-word with same rating and date but different timestamps. This suggests possible duplicate or artificially generated review.

This WW Score of 82.1 should be treated with CAUTION despite HIGH confidence in data volume. While the company demonstrates genuine strengths in responsiveness, technical knowledge, and fair pricing for straightforward jobs, the documented pattern of accountability failures, safety violations, and quality control issues with complex projects creates significant risk. The score reflects an average across many positive routine jobs and several serious failures; customers should be aware that performance appears highly dependent on job complexity and whether complications arise.

ARMS Rooter and Plumbing, operated primarily by Angel Martinez, receives overwhelmingly positive feedback across all four dimensions, with the vast majority of reviewers praising his punctuality, friendly demeanor, responsiveness, and transparent pricing. Pricing stands out as a particular strength, with multiple reviewers explicitly noting fair hourly rates, free estimates, and instances where Angel charged nothing or less than quoted for simple fixes. Project completion scores are strong but modestly reduced by three negative reviews: one citing an incomplete service due to a dispute over credit card handling policy, one citing a broken sprinkler valve during service, and one citing rude follow-up communication and an overlooked scope item with a warranty dispute. Experience scores are high, with numerous reviewers describing Angel as knowledgeable, skilled at diagnosis, and thorough in his workmanship. The score is tempered slightly by the recency of the negative reviews, with the credit card dispute occurring in October 2024, and the bulk of positive reviews being more than two years old.

• RECENCY CONCERN: The most recent review (October 2024) is a 2-star complaint about a service refusal and unprofessional dismissal of a customer. This is the most current data point and should be weighted accordingly.
• RECENCY CONCERN: The majority of reviews (approximately 38 of 47) are dated 2022 or earlier, with many from 2016-2018. Business practices and staffing may have changed since then.
• NEGATIVE PATTERN — PROJECT COMPLETION: Three separate reviews (1-star, 2017; 1-star, 2018; 1-star, 2024) describe incomplete work, a broken valve, and a service refusal respectively. These are distinct incidents and not isolated.
• POSSIBLE REVIEW CLUSTERING: A notable cluster of 5-star reviews dated exactly '2018-06-11', '2021-06-10', '2022-06-10', and '2023-06-10' with no specific timestamps (all 00:00:00) and generic praise language warrants mild scrutiny. These may be legitimate but lack the specificity of other reviews.
• ONE REVIEW ('Angel is so helpful', 5-star, 2020-06-10) is too vague to contribute meaningful scoring data and was excluded from dimension scoring.
• NO FAKE REVIEW PATTERN CONFIRMED: While some reviews share generic phrasing, the majority contain specific job details, named individuals, and unique circumstances, suggesting the review base is largely authentic.

This WW Score is based on a substantial volume of 47 reviews spanning approximately 9 years, with HIGH confidence across all four dimensions, but should be interpreted with caution given that the most recent review is negative, the bulk of positive reviews are over two years old, and three distinct 1-star complaints highlight real service failures in professionalism and project completion.

McKenzie (Vallejo Plumbers) demonstrates strong professionalism with consistent praise for punctuality, responsiveness, and courteous communication across 28 reviews. His technical expertise is well-documented with 18 mentions of skilled problem-solving and knowledge, particularly in water heater installations and complex plumbing diagnostics. Pricing is fairly represented across 12 mentions as reasonable and transparent. However, project completion shows some vulnerability: while most jobs are completed successfully, three negative reviews (2023-12-30, 2022-03-01, 2020-07-08) document incomplete work, missed appointments, and poor cleanup, pulling this dimension to 79. The 2023-12-30 review is particularly serious—abandoning an open water heater installation—though the 2022-03-01 missed estimate and 2020-07-08 cleanup/defective work issues also undermine reliability. Overall score of 82.1 reflects strong capability tempered by inconsistent follow-through on a meaningful minority of jobs.

• Three significant negative reviews (2023-12-30, 2022-03-01, 2020-07-08, 2018-09-08) document serious failures: incomplete work with open pipes, missed appointments without notice, poor cleanup, and last-minute cancellations. These are not isolated complaints but pattern indicators of reliability issues.
• 2023-12-30 review alleges McKenzie operates as sole proprietor while misrepresenting licensure/bonding status and unable to produce license for city permits. This is a critical red flag regarding legitimacy and regulatory compliance.
• Majority of reviews (24 of 34) are from 2020-2022, with only 4 reviews from 2024. Recency bias suggests recent performance may differ from historical data. The two most recent 2024 reviews are both 5-star, but sample size is too small to confirm improvement.
• One review (2022-01-16) uses generic hyperbolic language ('absolute best', 'lifesaver', 'amazing') with minimal specific detail, which is atypical of the more detailed positive reviews. However, overall review corpus does not show systematic fake review patterns—most reviews contain specific job details and legitimate criticism where present.
• Inconsistency in name spelling across reviews (McKenzie, Mackenzie, Mckenzie) suggests either multiple data entry errors or potential identity confusion, though context indicates single operator.

This WW Score of 82.1 should be treated with MODERATE-to-HIGH caution: while the score reflects genuinely strong professionalism and expertise supported by 28+ detailed positive reviews, the three serious negative reviews documenting incomplete work, missed appointments, and regulatory concerns represent material risk that is not fully captured in the numerical score. Customers should verify current licensing/bonding status independently and establish clear completion expectations before engagement.

Lorenzo at Legit Plumbing demonstrates strong professionalism, fair pricing, and technical expertise across most reviews, with consistent praise for responsiveness, honesty, and quality workmanship. However, the WW Score is tempered by one severely negative review (1-star, 2020-03-19) documenting a catastrophic project failure involving poor planning, incompetent execution, and incomplete remediation—a critical incident that significantly impacts the project completion dimension. The overwhelming majority of reviews (16 of 18) are highly positive and span over a decade, suggesting Lorenzo's typical performance is excellent, but the single major failure demonstrates real risk and inconsistency in execution.

• One severely negative review (2020-03-19, 1-star) describes a major project failure with a different team member (Darnell) rather than Lorenzo directly. This creates ambiguity about whether the failure reflects Lorenzo's oversight or a team quality-control issue. This incident significantly depresses the project completion score.
• One negative review (2021-02-13, 2-star) documents poor initial responsiveness and failure to follow up with a quote. This is the only communication failure mentioned and occurred over 3 years ago.
• Most reviews are older than 12 months (15 of 18 reviews are from 2019 or earlier). Only 3 reviews are from 2020 or later, limiting recency data. The most recent positive review is from 2022, but the most recent negative review is from 2021.
• Several reviews contain very similar phrasing and structure (e.g., multiple reviews mention 'honest,' 'reliable,' 'reasonable prices,' 'Westside,' and long-term relationships). While this could reflect genuine consistent experience, the pattern warrants noting. However, reviews also contain specific, detailed anecdotes (water hammer diagnosis, bidet installation failure, greywater certification) that suggest authenticity rather than fabrication.
• The bidet installation review (2020-03-19) names a different team member (Darnell) and criticizes the entire company as 'incompetent,' but most other reviews specifically praise Lorenzo. This suggests potential inconsistency in team quality or that the negative review may reflect a one-time staffing issue rather than Lorenzo's personal performance.

This WW Score of 82.1 is reliable with HIGH overall confidence due to substantial mention counts across all dimensions and a large sample size (18 reviews). However, the score is meaningfully depressed by one catastrophic project failure and should be interpreted as reflecting Lorenzo's typical strong performance tempered by documented execution risk. The age of most reviews (pre-2020) and limited recent data suggest caution in assuming current performance matches historical patterns. Prospective customers should expect excellent professionalism and pricing but should clarify project oversight and team composition given the documented failure.
