Justin Miller demonstrates consistently strong performance across all dimensions. Professionalism is his standout strength, with 19 reviews explicitly praising punctuality, communication, cleanliness, responsiveness, and attitude. Project completion is solid with 16 mentions confirming timely delivery, follow-through on commitments, and callback service. Experience is well-documented across 12 reviews highlighting technical knowledge, quality workmanship, and problem-solving ability. Pricing shows fair value in 6 mentions, though one review noted costs were 'a little high' and another indicated a landscape lighting follow-up was not completed. The WW Score of 87.2 reflects a highly reliable contractor with strong execution and professional standards.

• 5 reviews contain minimal or no usable text ('unknown', 'As explained above', 'see above', 'DID NOT USE', 'As indicated above') — these were excluded from scoring but represent 16% of total reviews
• All reviews are older than 12 months; most are from 2007–2014 with only one from 2015. Recent performance data is unavailable
• One negative signal: landscape lighting project was not followed through (2013 review, 3-star rating), suggesting scope limitations or follow-through issues on certain work types
• High concentration of 5-star ratings (24 of 26 usable reviews) is typical for Angie's List but limits ability to identify weaknesses

This score is reliable for assessing historical performance quality and professionalism standards, but should be treated with caution due to age of reviews (all pre-2016) and lack of recent customer feedback to confirm current service levels.

Precise Plumbing (led primarily by Jay/J. Cruz) earns strong marks across all four dimensions, driven by an enormous volume of reviews spanning nearly a decade. Professionalism is the standout dimension, with hundreds of reviewers explicitly praising punctuality, responsiveness, courteous communication, and willingness to respond to emergencies at odd hours. Pricing scores well overall — the majority of reviewers describe costs as fair, affordable, or lower than competing quotes — but a small number of negative reviews cite overcharging, hidden fees, or prices higher than expected, which moderates the score. Project completion is solid but not perfect: the vast majority of jobs were finished completely and to customer satisfaction, but several negative reviews describe incomplete work, no-shows after initial visits, and one case of abandoned work with no refund. Experience scores highly, with many reviewers noting skilled diagnostics, use of camera technology, creative problem-solving, and superior results compared to prior plumbers — though a few reviews describe rushed or incorrect initial work requiring callbacks.

• DUPLICATE REVIEWS DETECTED: A significant number of reviews appear to be exact or near-exact duplicates posted on the same or adjacent dates (e.g., multiple identical reviews dated 2024-05-28, 2024-05-14, 2023-12-09, 2023-11-29, 2023-11-27, 2023-11-13, 2023-09-08, 2023-08-04, 2023-07-31, 2023-07-29, 2023-06-19, 2023-06-07, 2023-06-02, 2023-05-26, 2023-04-17, 2023-03-31, 2023-03-15, 2023-03-12, 2023-02-19, 2022-11-29, 2022-11-19, 2022-11-13, 2022-11-08, 2022-10-09, 2022-10-01, 2022-09-23, 2022-07-28, 2022-02-23, 2021-12-02, 2021-08-09, 2021-07-07, 2021-06-16, 2021-05-10, 2021-04-06, 2021-04-01, 2021-03-18, 2021-02-09 x4, 2021-02-08, 2021-01-26, 2021-01-23, 2021-01-12, 2020-09-29, 2020-09-24, 2020-08-28, 2020-08-12, 2020-08-07, 2020-06-11, 2020-05-18, 2020-04-16, 2020-04-05, 2020-01-10, 2019-12-02, 2022-01-31, 2024-01-10, 2024-06-07). These duplicates inflate the apparent review count and may reflect a platform aggregation artifact or review manipulation. Confidence in raw review count is reduced accordingly.
• NEGATIVE REVIEWS PRESENT: At least 7 reviews rate the company 1.0–1.5 stars. Issues cited include: abandoned work after payment (Dec 2022), overcharging and no-show after initial visit (Oct 2014), price gouging on slab leak detection and incorrect leak location (Mar 2020), profanity from a technician and no refund issued (May 2020), flooding caused by improperly installed washing machine hoses with disputed liability (Dec 2019), failure to return calls (May 2024), and incorrect information provided to a customer with no follow-up (May 2017). These represent a meaningful minority of the review base and indicate inconsistency in service quality.
• MULTIPLE TECHNICIAN NAMES: Reviews reference Jay/J. Cruz, George, Marc/Mark, Alan/Allan, Hector, John, James, Lee, Silas, Eric, Alfonso, Malik, Devine, Ryan, Tony, JoJo, Isaac, and others. This suggests either a large crew or possible review aggregation across multiple related but distinct business entities or franchises, which may affect score reliability.
• RECENCY NOTE: The majority of reviews with substantive detail are from 2020–2025, which is positive for recency weighting. However, a meaningful cluster of reviews dates to 2014–2019 and some practices described in older negative reviews (no-shows, overcharging, profanity) may or may not reflect current operations.
• BLANK REVIEWS: Several reviews contain no text and only a 5-star rating. These were excluded from dimension scoring as they provide no usable data.
• ONE REVIEW DATED 2004: A single review dated 2004-04-28 was noted but given negligible weight due to extreme age.

This WW Score carries HIGH overall confidence given the large volume of substantive reviews, but should be interpreted with caution due to confirmed duplicate reviews inflating counts, a consistent minority of serious negative experiences, and possible multi-entity review aggregation — the true score likely falls in the 80–87 range.

Expert Plumbing demonstrates strong technical competence and generally reliable service delivery, with particularly high marks for experience and professionalism. However, pricing practices significantly undermine the overall score, with numerous complaints about emergency surcharges, overcharging, and unfair pricing relative to work performed. While most reviews praise punctuality, communication, and workmanship quality, the company's pricing strategy—especially for emergency calls and simple jobs—creates substantial customer dissatisfaction. Project completion is solid overall, though several no-show and follow-up failures are documented. The company shows inconsistency: excellent service from individual technicians (Levon, Andrei, Tony, Alex) contrasts with organizational failures in scheduling, follow-up, and billing transparency.

• PRICING PATTERN: Systematic complaints about emergency service markups (3x normal rates) and overcharging for simple jobs (e.g., $375 for valve shutoff, $495 for ice maker valve). At least 12 reviews explicitly mention unfair or excessive pricing.
• NO-SHOW AND FOLLOW-UP FAILURES: Multiple documented instances of missed appointments without notification, failure to return calls, and broken promises to follow up with quotes or callbacks (reviews from 2020-07-25, 2019-07-28, 2018-12-16, 2014-11-22).
• BILLING DISPUTES: Evidence of billing discrepancies, misrepresented charges, and disputes over what was quoted vs. what was charged (reviews from 2020-10-26, 2020-03-16 showing legal action taken against customer).
• RECENCY CONCERN: Most negative reviews cluster in 2014-2020 period. Only 1 review from 2024 (positive) and 1 from 2021 (positive). Recent data is sparse, limiting confidence in current operational status.
• INCONSISTENCY: Stark contrast between individual technician quality (frequently praised) and organizational/management failures (scheduling, billing, follow-up). Suggests systemic operational issues despite skilled workforce.
• POTENTIAL FAKE REVIEW PATTERN: Several reviews use nearly identical phrasing ('highly recommend,' 'great job,' 'professional') with minimal specific detail, though most reviews do contain substantive information, so confidence in fake review detection is limited.

This WW Score of 78.2 should be treated with caution due to significant recency bias (most data from 2014-2020) and a clear bifurcation between technical competence and business practices. The score reflects strong workmanship and professionalism from individual technicians, but is substantially penalized by documented pricing abuses and organizational failures. Current reliability is uncertain given sparse recent reviews; the company may have improved or deteriorated since 2021. Customers should prioritize obtaining detailed written quotes and clarifying all fees before engaging services, particularly for emergency calls.

General Plumbing & Rooter demonstrates strong technical competency and project completion rates, with many customers praising specific technicians like Johnny Morgan, Juan, and Ray for their expertise and thoroughness. However, the company is significantly hampered by persistent communication and dispatch failures, with multiple customers reporting no-shows, missed callbacks, and poor follow-up. Pricing is a major concern, with numerous complaints about overcharging, unnecessary upsells, and aggressive estimates that are 4-6x higher than competitors. While individual technicians often deliver professional service, systemic issues with management, office staff, and dispatch coordination create a gap between field performance and overall customer experience.

• PRICING PATTERN: Multiple reviews (2022-2024) document price-gouging behavior, with estimates 4-6x higher than competitors for identical work. Examples include $96k sewer estimate vs $16k competitor quote, $2100 water jetting vs $60 rental cost, and $1100 shower valve replacement vs $90 competitor quote.
• COMMUNICATION CRISIS: Systematic pattern of dispatch failures, no-shows, and unanswered callbacks spanning 2012-2024. Customers report waiting 6+ hours without contact, multiple unanswered callback promises, and ghosting after initial contact.
• FAKE REVIEW INDICATORS: Multiple empty reviews with 5-star ratings (dates 2024-06-09, 2020-06-10, 2019-06-11) and several suspiciously generic praise reviews with identical phrasing patterns suggest potential review manipulation.
• MANAGEMENT QUALITY ISSUES: One detailed 2020 review explicitly criticizes manager 'Chris' for rudeness and condescension, particularly toward female customers, while praising field technicians Ray and Nacho.
• DIAGNOSTIC DISHONESTY: Multiple reviews document incorrect diagnoses leading to unnecessary expensive repairs (e.g., claiming toilet 'defective' when floor was unlevel, recommending full pipe replacement when only flange repair needed, misdiagnosing offset pipes).
• RECENCY CONCERN: While recent reviews (2024) show continued communication problems, the company appears to have had stronger performance 2017-2019 period. Recent trend suggests ongoing systemic issues.
• INCONSISTENT QUALITY: Stark contrast between 5-star reviews praising specific technicians and 1-star reviews from same time periods, indicating field performance varies dramatically by technician and management oversight is weak.

This WW Score of 72.8 should be interpreted with caution: while the company demonstrates genuine technical expertise and project completion capability (evidenced by HIGH confidence scores in experience and completion), the score is significantly dragged down by pervasive, documented communication failures and pricing practices that appear predatory. The company's reliability is highly dependent on which technician is assigned; customers should expect strong field work but should be prepared for dispatch issues, aggressive pricing, and poor office communication. The score reflects a company with capable technicians operating within a dysfunctional management and dispatch system.

MTZ Pro Plumbing receives consistently strong feedback across all four scored dimensions. Professionalism is the most frequently cited strength, with multiple reviewers praising responsiveness, punctuality, respectful demeanor, and clear communication. Experience and workmanship are also well-supported, with reviewers noting high-quality installations, identification of prior errors, and a city inspector independently validating the work quality. Project completion is positively noted, particularly in one review that explicitly called out how Gilberto ensured all issues were resolved before leaving the job site. Pricing is mentioned favorably in three reviews, with customers describing quotes as fair and cost-effective compared to competitors, though this dimension carries only moderate confidence due to the limited mention count.

• All 7 reviews are 5-star ratings with no negative or mixed feedback, which warrants mild caution.
• However, reviews contain specific job details (slab leak, gas fireplace line, water softener, elevated flange, pipe replacement under house), which reduces the likelihood of fabricated reviews.
• Review recency is a concern: only 1 review is from the past 12 months (2023), 1 from 2022, 1 from 2021 (x2), and 3 from 2020 or earlier. The majority of reviews are over 2 years old, which limits confidence in reflecting current performance.
• Total review count is low (7 reviews), which limits statistical reliability of all dimension scores.

This WW Score carries moderate overall reliability — the reviews are specific and credible in content, but the small sample size and predominantly older review dates (most pre-2022) mean the score may not fully reflect the contractor's current quality or consistency.

Mike demonstrates strong technical expertise and responsiveness across most dimensions, with 7 of 8 reviews praising his professionalism, quick response times, and quality workmanship. However, a critical 1-star review from March 2022 reveals significant project completion failures: a missed appointment, late arrival (3-4 hours), incomplete work, and failure to follow up on promised corrections despite customer follow-up a month later. This serious breach substantially lowers the project completion score. Pricing is consistently described as reasonable and fair across three mentions. The overall WW Score of 82.3 reflects strong capability undermined by a documented pattern of non-follow-through on one project.

• RECENCY CONCERN: 6 of 8 reviews are from 2021-2022 (2+ years old). Only 2 reviews are from 2022 or later. Limited recent data to assess current service quality.
• CRITICAL PROJECT FAILURE: One detailed 1-star review documents serious issues—missed appointment, late arrival, incomplete work, and failure to respond to follow-up messages one month later. This is not a minor complaint and directly contradicts claims of reliability.
• POTENTIAL PATTERN: The March 2022 review mentions this was a 'handyman' job (security camera installation), not plumbing. Review set includes mixed service types (plumbing, garage door, countertop work, toilet installation). Consistency of quality across service types is unclear.
• POSSIBLE FAKE REVIEW PATTERN: Reviews from 2021-2022 show suspiciously similar positive phrasing ('great service,' 'highly recommended,' 'go-to service') with minimal specific detail in several cases. However, the 1-star review provides granular, credible detail, suggesting the dataset is not entirely fabricated.

This score should be treated with caution due to age of data (most reviews 2+ years old) and a documented serious failure in project completion that contradicts the predominantly positive ratings. The WW Score of 82.3 reflects capability but masks a material reliability risk evidenced by the March 2022 incident.
