Joksan and Creativity Plumbing earn strong scores across all four dimensions, driven by an exceptionally large and detailed review base spanning 2020–2024. Professionalism scores are high but tempered by two notable negative reviews: one documenting two consecutive no-shows with no communication (1-star, June 2021), which is a serious reliability failure. Pricing scores well overall with many reviewers explicitly praising reasonable and competitive rates, but one 1-star review (November 2023) specifically called out a quote that was 'CRAZY high' — double what a competitor charged — which meaningfully pulls the pricing score down from what would otherwise be near-perfect. Project completion is strong, with the vast majority of reviewers confirming jobs were finished completely, on time, and with follow-through, including emergency same-day and weekend calls. Experience scores highest, with dozens of reviewers explicitly praising Joksan's technical knowledge, diagnostic skill, and quality of workmanship across a wide variety of plumbing tasks.

• Two legitimate negative reviews exist and must not be dismissed: (1) A June 2021 1-star review documents two consecutive no-shows in a single day with no communication until after the fact — a serious professionalism failure. (2) A November 2023 1-star review reports a quote that was approximately double the price ultimately paid to a competitor, suggesting possible inconsistency in pricing practices.
• A moderate pattern of generic short reviews exists (e.g., 'Quick and professional! Recommend to everyone. 5 stars. Good job.' and 'Very helpful and solid fix! Clear the bathtub clearly!') that lack specific detail. These are not conclusively fake but reduce confidence slightly in the aggregate score.
• A cluster of reviews from August 2021 (August 7, 8, 11, 24, 25, 26, 29 x3) — nine reviews in one month — is unusually dense. While individually plausible, this volume warrants mild scrutiny.
• The majority of reviews (approximately 50 of 68) are older than 12 months as of mid-2025. Only about 4 reviews are from the past 12 months (mid-2024 to mid-2025), meaning recent performance data is limited. The most recent reviews (2024) remain positive.
• Multiple reviewers note Joksan arrived late to appointments but communicated proactively about delays. This is a recurring minor pattern that slightly reduces the professionalism score despite generally positive framing by reviewers.

This WW Score is based on a large, detailed, and multi-year review set with HIGH confidence across all four dimensions; it is broadly reliable, though users should note two substantive negative reviews regarding no-shows and pricing inconsistency, a thin recent review base from the past 12 months, and a handful of suspiciously generic short reviews that modestly temper full confidence.

EJ Plumbing and associated technicians (Gilbert, Avila Plumbing) receive overwhelmingly positive feedback across all four dimensions, with professionalism being the most frequently cited strength — reviewers consistently highlight punctuality, courtesy, clear communication, and cleanliness. Project completion scores are strong, with multiple reviewers noting jobs finished on time, thoroughly tested, and with no abandoned work, though one 4-star review flagged a communication failure around scheduling notice. Pricing is generally described as fair, reasonable, and transparent, with one older review noting pricing was slightly high for a sewer line job, which tempers the score modestly. Technical experience is well-documented across a wide variety of jobs including re-pipes, tankless water heater installs, RO systems, sewer line repairs, and leak detection, with reviewers frequently praising technicians' knowledge and problem-solving. The volume and recency of reviews (the majority from 2025) lend strong reliability to these scores.

• 6 reviews contained no text at all — only a star rating. These were excluded from dimension scoring as they provide no usable evidence.
• The review dated 2006-07-07 (two reviews) are extremely old — nearly 19 years — and were given minimal weight. Both are written in all-caps, which is unusual, but content is specific enough to not be flagged as fake.
• Several reviews from 2020–2024 appear to be for a solo plumber named Gilbert operating under 'Avila Plumbing,' while the majority of 2025 reviews reference 'EJ Plumbing' or 'EJ Home Services' with named technicians. These may represent two distinct business entities or a rebranding. Scores have been pooled as submitted but this mixed attribution is a reliability concern.
• A mild pattern of generic 5-star praise exists (e.g., 'Excellent', 'Fast, Fair, Effective', 'Great service and communication') with no supporting detail. These were not scored for specific dimensions but do not appear to be coordinated fake reviews given the volume of highly specific reviews alongside them.
• All reviews are 4 or 5 stars with no reviews below 4 stars. While this may reflect genuine quality, it slightly elevates suspicion of review curation or selective solicitation. Confidence is maintained at HIGH due to the specificity and volume of detailed reviews.

This WW Score is based on a large volume of recent, detailed, and largely specific reviews and can be considered highly reliable, with the caveat that the possible mixing of two distinct business entities (EJ Plumbing and Avila/Gilbert solo work) and the complete absence of any negative reviews warrants mild caution.

Aqua Flow Plumbing, led primarily by Dave, receives overwhelmingly positive feedback across all four scored dimensions. Professionalism is a standout strength, with numerous reviewers explicitly praising punctuality, responsiveness, same-day and weekend availability, friendly communication, and clean workmanship. Pricing is consistently described as fair, reasonable, or even significantly below competitor quotes, with one reviewer noting a bid one-fifth the price of a competing plumber. Project completion is well-documented, with reviewers repeatedly noting that Dave resolved issues other plumbers had failed to fix, completed jobs quickly and thoroughly, and followed through even under difficult conditions such as rain, mud, and late-night emergencies. Experience and technical skill are highlighted across many reviews, including successful diagnosis of a long-standing water hammer problem, creative access solutions to avoid unnecessary damage, and correct identification of faults left by prior contractors. One negative review from 2011 cited poor customer service but offered no specific detail, and its age significantly limits its weight.

• Two reviews dated 2023-09-27 appear to be near-identical duplicates (same full review text, same rating, posted within 30 minutes of each other). These were counted as one unique mention to avoid inflating scores.
• The majority of reviews are all 5-star ratings with only one 1-star review. While the volume and specificity of positive reviews lend credibility, this pattern warrants mild caution.
• Several reviews from 2009–2013 are over 10 years old and were given reduced weight per recency rules. The bulk of substantive, detailed reviews are from 2017–2024, which supports overall score reliability.
• The single negative review (1 star, 2011) states 'zero stars for customer service' but provides no specific details about what occurred. Due to lack of specificity and age, it was noted but had minimal scoring impact.
• No clearly fabricated or bot-generated reviews were detected. Most positive reviews include specific job details, named individuals, and unique circumstances, which supports authenticity.

This WW Score is based on 34 usable reviews spanning 2009–2024, with the majority of detailed reviews from 2017–2024, a high mention count across all four dimensions, and strong specificity in reviewer accounts — making this score reasonably reliable, though the near-universal 5-star pattern and one duplicate review warrant a small degree of caution.

CPI Plumbing receives consistently strong marks across all four dimensions, with professionalism being the most frequently cited strength — reviewers repeatedly highlight punctuality, courteous communication, and clear explanations from named technicians like Shamir, Dustin, and Luis. Pricing is generally viewed as fair or reasonable, with one reviewer noting it is 'little pricey' and another explicitly comparing CPI favorably to a competitor's bid, keeping the pricing score honest rather than inflated. Project completion scores well, with multiple reviews confirming jobs were finished efficiently, follow-through was honored (e.g., Shamir returning days later to complete a pipe replacement), and no abandoned work was reported. Experience and technical skill are well-documented across diverse job types including water heater replacement, sewer line hydrojetting, HPWH repair, and emergency leak diagnosis, supporting a strong but not perfect experience score. One point of caution is the presence of duplicate and near-duplicate reviews which slightly inflates mention counts and warrants a flag.

• DUPLICATE REVIEWS DETECTED: The toilet/snack wrapper review appears three times with nearly identical text (two dated 2024-06-02, one undated). The HPWH review appears twice with nearly identical text (one dated 2024-06-27, one undated). The Dustin drain pipe review appears twice (one dated 2024-04-22, one undated). The Shamir best service review appears twice (one dated 2024-04-24, one undated). The CPIS leak repair review appears twice (one dated 2024-06-26, one undated). These duplicates were identified and treated as single unique reviews for scoring purposes to avoid inflating mention counts.
• UNDATED REVIEWS: A significant portion of reviews (approximately 20) have no date attached. It is impossible to assess recency for these reviews. If many are older than 12 months, the score may not reflect current service quality.
• GENERIC REVIEWS: Several reviews ('Good service', 'Quick response and good services!', 'Able and Kevin did a fabulous job! Everything is perfect.') contain no specific detail and contribute minimal scoring evidence. These were excluded from dimension scoring but counted in total reviews analyzed.
• PATTERN NOTE: The volume of 5-star reviews with no negative feedback and the presence of duplicates warrants moderate caution. However, many reviews do include specific technician names, job details, and nuanced observations, which reduces the likelihood of wholesale fabrication.

This WW Score is moderately reliable — the high volume of reviews and specific, detailed accounts from multiple named technicians support confidence, but the presence of duplicate reviews, a large number of undated entries, and a handful of generic reviews introduce enough uncertainty that the score should be treated as a strong positive signal rather than a precise measurement.

Michael (and occasionally named associates Josh, William, and Surgey) earns overwhelmingly positive marks across all four dimensions, with professionalism being the standout strength — punctuality, communication, courtesy, and cleanliness are mentioned repeatedly and consistently across dozens of recent reviews. Project completion is also very strong, with the vast majority of jobs described as finished same-day or within the promised timeframe; the one notable exception is a 2022 review (Serge) describing an abandoned vanity installation and unreturned calls, which meaningfully tempers the completion score. Pricing is generally praised as fair and competitive, with multiple reviewers noting Michael talked them out of unnecessary work or waived charges entirely — however, two negative pricing reviews (a $250 drain quote called non-affordable, and a $150 charge for a 15-minute visit) prevent a higher score. Experience and technical knowledge are consistently praised, including successful diagnosis of complex or obscure issues that other plumbers could not resolve. The score is highly reliable given the large volume of recent, detailed, and specific reviews.

• MULTIPLE TECHNICIAN NAMES: Reviews reference at least four different technicians — Michael/Mike, Josh, William, and Surgey — suggesting this may be a multi-person operation or aggregated business profile rather than a single contractor. Scores may reflect team-level rather than individual performance.
• VERY OLD REVIEWS: Several reviews date from 2013–2016 and include entries with no review text ('unknown', 'See above', 'He did an excellent job in all respects.'). These were given minimal weight in scoring due to age and lack of usable content.
• ABANDONED JOB FLAG: One 3-star review (Serge, Feb 2022) explicitly describes an incomplete job — toilets installed but a promised vanity installation was never completed, with calls and texts going unanswered for two weeks. This is a meaningful project completion concern and was factored into the project completion score.
• NEGATIVE PRICING SIGNALS: Two reviews explicitly criticize pricing — one calling a $250 drain quote non-affordable, and another objecting to a $150 charge for a 15-minute visit with no resolution. These were weighted against the many positive pricing mentions.
• COMMUNICATION FAILURE: One 2-star review (Feb 2024) reports that after an initial response, the contractor asked for a callback number and then never followed up, moving on to the next customer. This is a responsiveness concern factored into professionalism.
• POSSIBLE REVIEW AGGREGATION: The mix of technician names, geographic references (Naperville, LaGrange Park, Maple Valley, Shoreline Amphitheater), and review date spans suggest this profile may aggregate reviews from multiple service areas or time periods under one business listing. Consumers should verify current operator details.
• NO FAKE REVIEW PATTERNS DETECTED: Despite the high volume of 5-star reviews, the majority contain specific job details, named technicians, described problems, and varied writing styles. No significant fake review pattern was identified.

This WW Score is based on a large sample of 101 reviews spanning 2013–2024, with the majority being recent (2023–2024) and highly detailed, yielding HIGH confidence across all four dimensions — however, consumers should note the multi-technician profile, a documented case of an abandoned job, and two credible negative pricing complaints, which introduce moderate uncertainty around consistency.

MTZ Plumbing earns very strong marks across professionalism, project completion, and experience, with the overwhelming majority of reviewers explicitly praising punctuality, communication, courteous behavior, and thorough workmanship across a wide range of plumbing jobs. Project completion scores are high, with numerous reviews confirming jobs finished correctly the first time, callbacks honored, and even additional work completed at no extra charge. Experience is well-documented through technically complex jobs such as whole-house repiping, sewer line replacement, tankless water heater installation, and difficult cartridge extractions. Pricing is the weakest dimension: while many reviewers describe fair or reasonable pricing, three separate reviews (rated 1–3 stars) explicitly state that MTZ quotes came in significantly higher than competitors — in one case 5x higher and in another $6,100 more than the chosen alternative — which meaningfully suppresses the pricing score. The overall WW Score of 87.4 reflects a contractor with genuinely strong service delivery but inconsistent pricing competitiveness.

• PRICING CONCERN: At least 3 reviews (1-star, 1-star, 2-star) explicitly describe MTZ quotes as dramatically higher than competitors — one reviewer received a quote 5x higher than four other plumbers, another saved $6,100 by going elsewhere, and a third was quoted $7,000 vs. $1,200 from their regular plumber. This is a material and recurring concern that significantly impacts the pricing score.
• POSSIBLE FAKE OR LOW-QUALITY REVIEWS: Five reviews dated 2022-01-18 are extremely brief, generic, and lack any specific detail ('He is the best plumber. Never had problems.', 'Always recommend to friends, Someone you can trust, highly recommend.', 'Over all good experience. I have already recommended him to a friend.', 'They did a great job, really smart contractor and he did a real expert plumbing job.'). These reviews share the same date, are all 5-star, and contain no job-specific information. They were excluded from usable data counts for scoring purposes and flagged as potentially inauthentic.
• RECENCY NOTE: The majority of reviews span 2020–2024, with a strong cluster in 2021–2023. Reviews from the past 12 months (late 2023–2024) remain consistently positive, suggesting no meaningful decline in service quality over time.
• ONE 3-STAR REVIEW noted excessive verbal warnings about payment even if unsuccessful, high after-hours pricing, and repeated upselling of an expensive dig option — a minor but notable pattern consistent with the pricing concerns raised in the 1-star reviews.

This WW Score is based on a large, diverse, and predominantly detailed review set spanning multiple years and technicians, giving HIGH confidence in the professionalism, project completion, and experience scores; however, the pricing score should be treated with caution given credible and specific complaints about significantly above-market quotes in multiple independent reviews.
