Dentzer Plumbing demonstrates strong overall performance with particular strengths in project completion and professionalism. The company consistently delivers timely service, responsive communication, and quality workmanship across multiple job types. Pricing receives a moderate score due to mixed feedback—while many customers praise fair and reasonable rates, one detailed 2018 review raised concerns about deceptive pricing practices and poor quality work (galvanic corrosion issue). Two isolated incidents of no-shows and one payment processing dispute slightly temper the otherwise excellent reputation. The business benefits from long-standing customer relationships and family-business credibility spanning multiple generations.

• One detailed negative review (2018-06-13) alleges deceptive pricing, poor cleanup, payment processing issues, and substandard workmanship (galvanic corrosion on copper pipes). This is a substantive complaint with specific technical details and should not be dismissed.
• One no-show incident reported (2017-09-14) where Bernie failed to appear or call for an appointment, though reviewer noted Joe was reliable.
• Review from 2013 contains repetitive phrasing ('No finer plumbers anywhere' stated twice), suggesting possible generic praise, though this is minor.
• Most reviews are older than 12 months (16 of 25 reviews predate 2019). Only 2 reviews from 2024 and 1 from 2023. Recent performance data is limited.
• Pricing feedback is polarized: majority describe rates as 'fair,' 'reasonable,' or 'lower than competitors,' but one detailed review claims 'absurd pricing' and deceptive practices. This suggests either inconsistent pricing practices or service-dependent pricing variation.

This WW Score of 84.2 is reliable with HIGH overall confidence due to substantial mention counts across all dimensions (9-20 mentions per category). However, the score should be interpreted with caution regarding pricing: while most customers report satisfaction, one credible 2018 complaint with specific technical allegations (galvanic corrosion) and payment disputes suggests pricing practices warrant independent verification. The limited recent review data (only 3 reviews from 2023-2024) means current performance may differ from the historical average reflected here.

Arco Plumbing earns strong marks across all four dimensions, with professionalism being the most consistently praised attribute — punctuality, courtesy, shoe covers, cleanup, and clear communication appear repeatedly across decades of reviews. Project completion is also well-supported, with the vast majority of reviewers confirming jobs were finished as promised, callbacks were honored, and follow-through was reliable; however, two notable negative reviews (a 1-star sump pump failure with no callback, and a 1-star job abandonment citing the work was 'too much') prevent a higher score. Pricing receives a moderately positive but mixed score: many reviewers call prices fair or competitive, but several explicitly note Arco is on the higher end or not the cheapest option, and one reviewer rated them 3 stars specifically citing high prices. Experience scores well, with numerous reviewers citing skilled diagnostics, problem-solving on old or unusual plumbing, and technical knowledge — though one critical review alleged the company could not read architectural drawings and installed an undersized sump pump. One review (Westmont Plumbing, 1-star) appears to reference a different company entirely and was excluded from scoring.

• One review (1-star, Westmont Plumbing) references a completely different company and was excluded from scoring as it does not appear to be about Arco Plumbing.
• Two reviews appear to be near-identical duplicates: the tankless water heater review dated 2023-06-10 and 2022-12-29 share nearly identical text, suggesting a copy-paste or system duplication — treated as one data point.
• Two reviews dated 2019-03-26 are word-for-word identical, suggesting a duplicate submission — treated as one data point.
• Approximately 13 reviews contain no text (blank or 'unknown'), providing no usable data for any dimension — these were excluded from scoring.
• One review (2001-05-06) is over 20 years old and carries negligible weight under recency rules.
• A significant portion of reviews (roughly 40+) are dated before 2022, meaning recency weighting reduces their influence on the final score.
• The 1-star sump pump review (2010-07-25) describes a serious safety failure — undersized pump installed and no callback after basement flooding — which is a meaningful flag for project completion and experience despite its age.
• The 1-star job abandonment review (2016-10-25) describes the company backing out of a $3,200 committed job and being rude — a meaningful flag for professionalism and project completion reliability.
• No strong pattern of fake reviews detected; most positive reviews include specific names, job types, and details. Generic praise reviews exist but are a minority.

This WW Score is based on a large volume of reviews spanning over a decade and carries HIGH overall confidence, though users should note that a small number of serious negative experiences — including a post-job abandonment, a sump pump failure with no follow-up, and pricing concerns — prevent a top-tier score and suggest occasional inconsistency in service delivery.

MD Plumbing earns strong marks across all four dimensions, driven by an overwhelming volume of reviews praising punctuality, responsiveness, fair pricing, and quality workmanship over more than a decade of service. Professionalism scores are tempered by a recurring minority of complaints about late arrivals without notification, one instance of a plumber being described as rude, and several cases of unreturned calls or no-shows — patterns that appear consistently enough across different reviewers to be credible. Project completion is similarly strong but is pulled down by a cluster of negative reviews describing incomplete work, a bait-and-switch sewer rodding job, a botched pedestal sink installation with no refund response, an unresolved clogged sink, and a $350 charge for zero progress on a frozen drain. Pricing is a genuine strength, with dozens of reviewers independently citing fair, transparent, and competitive rates, and several noting MD saved them thousands compared to competitor quotes. Experience scores well overall, with many reviewers praising problem-solving ability and technical knowledge, though the pedestal sink installation failure and the frozen pipe incident represent credible skill gaps in specific task types.

• DUPLICATE REVIEW DETECTED: The review beginning 'We've used MD Plumbing for multiple things over the years and always appreciated their attention to detail...' appears at least 4 times across different dates (2024-06-09, 2024-06-06, 2024-05-15 x2). This is a strong indicator of review manipulation or platform duplication artifacts.
• DUPLICATE REVIEW DETECTED: The review beginning 'We've been using MD Plumbing since the early 2000s...' appears in two nearly identical versions on 2024-01-11, one with and one without the detailed sewer backup narrative.
• DUPLICATE REVIEW DETECTED: The review beginning 'They were able to come out promptly when we had a pretty big issue with our sewer outlet...' appears twice on 2024-06-09 and 2024-06-06.
• DUPLICATE REVIEW DETECTED: The review beginning 'Knowledgeable, experienced, skilled, fairly priced...' appears twice on 2024-06-09 and 2024-06-06.
• DUPLICATE REVIEW DETECTED: The review beginning 'I called MD plumbing due to my hot water heater not working...' appears twice on 2024-05-22 with nearly identical text.
• DUPLICATE REVIEW DETECTED: The review beginning 'Got drips, clogs and cracked seats...' appears twice — once in 2014-07-24 and once in 2014-01-28 — with nearly identical text.
• DUPLICATE REVIEW DETECTED: The review beginning 'Marc and his team are fantastic! They just did my entire historic home...' appears twice — 2021-06-07 and 2019-10-09 — with nearly identical text.
• DUPLICATE REVIEW DETECTED: The review beginning 'I'm stingy with 5 star reviews...' appears twice on 2017-01-19 with nearly identical text.
• NEGATIVE PATTERN — NO-SHOWS AND UNRESPONSIVENESS: Multiple independent reviewers (2020-04-26, 2019-05-29, 2019-02-10, 2013-10-17, 2011-11-18) report MD Plumbing failing to show up for scheduled appointments or failing to return calls, with no apology or follow-up. This is a credible and recurring operational weakness.
• NEGATIVE PATTERN — INCOMPLETE WORK AND REFUND DISPUTES: At least three independent reviewers (2020-08-30, 2020-08-14, 2020-07-26 — likely the same customer filing multiple reviews about the pedestal sink; 2018-01-12; 2020-06-07 sink clog; 2022-08-18 bait-and-switch) describe paying for work that was not completed or was done poorly, with no refund or callback from the company.
• CAUTION — POSSIBLE SAME-CUSTOMER MULTI-REVIEW: The three negative reviews about a pedestal sink installation (2020-07-26, 2020-08-14, 2020-08-30) appear to be from the same customer filing escalating complaints. These have been counted as one incident for scoring purposes to avoid over-weighting a single dispute.
• RECENCY NOTE: The majority of reviews span 2010–2024. The most recent reviews (2024) are largely positive and include duplicates. Negative reviews are distributed across multiple years, suggesting these are not isolated incidents but recurring operational issues.
• CONFIDENCE REDUCTION APPLIED: Due to confirmed duplicate reviews inflating apparent review volume, scores have been calculated conservatively. Duplicate reviews were identified and de-weighted in the scoring assessment.

This WW Score is based on a large and long-running review dataset and carries HIGH overall confidence, but should be interpreted with caution due to confirmed duplicate reviews that artificially inflate volume, and a credible pattern of no-show and incomplete-work complaints that represent genuine operational risks for new customers.

North Coast Sewer Plumbing and Drainage earns strong scores across all four dimensions, driven by an exceptionally large and detailed review base spanning nearly a decade. Professionalism is the most frequently cited strength, with dozens of reviewers explicitly praising punctuality, courteous communication, responsiveness, and clean job sites. Pricing scores well due to numerous reviews explicitly comparing North Coast favorably against competitor quotes — often saving customers thousands of dollars — and multiple instances of no-charge visits or goodwill gestures. Project completion is also strong, with the vast majority of reviews confirming jobs were finished as promised, permits pulled, inspections passed, and follow-up work honored; however, four negative reviews (1-star) describe a flooded basement from an improperly glued sump pump discharge, an abandoned job with no follow-through, a broken supply line with disputed accountability, and a recommendation to replace working sump pumps, which meaningfully temper this score. Experience scores highly based on repeated explicit praise for technical knowledge, diagnostic skill, and problem-solving ability, including several cases where North Coast identified issues other companies missed entirely.

• Four negative reviews (1-star) are present and credible: one describes a basement flood caused by an improperly installed sump pump discharge line left unglued; one describes a technician breaking off a supply line fitting and the owner responding rudely and dismissively; one describes a job abandoned mid-service with no follow-up and a refusal to return without additional charge; one describes being told working sump pumps needed replacement. These are specific, detailed, and plausible complaints that reduce project completion and professionalism scores.
• One review (2022-06-08, 5 stars) references 'Welter Plumbing' and 'Dan' with no mention of North Coast by name — this review appears to be misattributed or posted to the wrong business profile and was excluded from scoring.
• One review (2017-08-09, 3 stars) describes a communication and integrity concern where work proceeded without customer approval, suggesting occasional lapses in client communication on complex jobs.
• A small number of reviews use somewhat generic praise language (e.g., 'Thorough, fast, knowledgeable and very courteous'), but the majority of reviews are highly specific with named employees, detailed job descriptions, and verifiable circumstances. No strong pattern of fake reviews detected.
• Review recency note: The review base spans 2014–2024. Approximately 20 reviews are from 2020 or earlier, meaning some scores reflect older performance. The most recent reviews (2023–2024) remain consistently positive, suggesting sustained quality, but the negative reviews are distributed across multiple years including 2019, 2020, 2021, and 2023.

This WW Score is based on 72 reviews with a high volume of detailed, specific, and independently verifiable content across all four scored dimensions, making it one of the more reliable assessments possible; the presence of four credible negative reviews has been factored into the scores and prevents artificial inflation.

Reeg Plumbing earns strong marks across all four dimensions, with the vast majority of reviewers praising punctuality, communication, and courteous service. Project completion is a particular strength — dozens of reviewers describe jobs finished on time, same-day or next-day responses to emergencies, and plumbers who go above and beyond the original scope. Experience is consistently highlighted, especially for older homes with complex or aging plumbing systems. Pricing scores slightly lower due to a recurring minority complaint about overcharging, double-billing for return visits when parts were unavailable, and at least one review alleging a quote that far exceeded the actual work performed — these are credible, specific complaints that meaningfully temper an otherwise strong pricing narrative. A small number of reviews also flag serious professionalism failures including a reported instance of the owner using an expletive toward a customer and another of hanging up on a client, which prevent the professionalism score from reaching the high 90s despite the overwhelming volume of positive feedback.

• DUPLICATE REVIEWS DETECTED: At least two reviews appear to be exact duplicates posted on different dates — 'We've had Reeg do urgently needed work on our 110yo home in Oak Park several times...' (2025-05-12 and 2025-05-09) and 'From inquiry to job complete these guys do it right!...' (2025-05-10 and 2025-05-07) and 'Couldn't be happier with the professional service...' (2025-05-10 and 2025-05-07). These are likely the same reviewer submitting duplicate entries or a platform artifact. These duplicates were counted only once per unique review for scoring purposes.
• PRICING COMPLAINTS — CREDIBLE AND SPECIFIC: Multiple reviewers (at least 3) describe being charged for two separate visits when the plumber did not have the required part on the first visit, resulting in bills exceeding $300 for minor repairs. One reviewer reported being quoted for 10-20 feet of piping but only 1 foot was replaced per pipe, with no response from the owner when they raised the concern. These are specific, detailed complaints that reduce pricing confidence.
• SERIOUS PROFESSIONALISM INCIDENT: One reviewer (1-star, Sept 2021) reports the owner responded to a scheduling complaint by calling them a 'douche' via email. Another reviewer (1-star, 2023) reports the owner told them to 'get a new plumber' and hung up after a parts-related dispute. These are isolated but serious incidents that are factored into the professionalism score.
• SCHEDULING DELAYS NOTED: One reviewer (3-star, Feb 2022) reported being told an estimate for an urgent job would take two weeks, forcing them to seek another plumber. One older review (2023) notes the company can get overscheduled causing delays. One review (2023) notes it is 'sometimes difficult to get a prompt appointment.' These are consistent enough to flag as a pattern.
• RECENCY NOTE: The majority of reviews with substantive detail are from 2022–2025, which is within the reliable recency window. Reviews from 2012–2016 are present but given lower weight. The most recent negative reviews (2023–2025) are given full weight.
• 8 REVIEWS CONTAINED NO TEXT — only a star rating. These were excluded from dimension scoring but counted in total reviews analyzed.
• FAKE REVIEW RISK: LOW-MODERATE. The confirmed duplicate reviews are a concern, but most positive reviews contain specific names, job types, and details that suggest genuine experiences. The overall pattern does not strongly suggest coordinated fake review activity beyond the identified duplicates.

This WW Score is based on a large volume of reviews (163 total, 155 with usable data) spanning over a decade, with the majority from 2022–2025, giving it HIGH overall confidence — however, consumers should note the recurring pricing complaints, confirmed duplicate reviews, and at least two documented serious owner professionalism incidents before making a hiring decision.

Roc's Plumbing earns strong marks across all four dimensions, with professionalism being the most consistently praised attribute — punctuality, communication, cleanliness, and courteous staff are mentioned in the overwhelming majority of reviews. Pricing is frequently described as fair, reasonable, and transparent, with multiple reviewers specifically noting that final charges matched quoted amounts. Project completion scores well overall, with most jobs described as thorough and fully resolved, though a small number of negative reviews cite an abandoned quote, a missed follow-up visit, and one instance of work alleged to be below code — these meaningfully temper the score. Experience and technical skill are praised across a wide range of job types, from emergency sewer repairs to complex repiping, though the negative reviews introduce enough doubt to prevent a top-tier score. The score is modestly reduced to account for a pattern of negative reviews that, while a minority, describe meaningful failures in responsiveness and workmanship quality.

• Four negative reviews (1-star and 2-star) describe significant failures: one alleges substandard work that did not meet code and improperly glued pipe joints; one describes a technician refusing to perform a simple repair and poor owner follow-up; one describes a quote that was never delivered after a month; and one describes a promised visit that never occurred with no callback for two weeks. These are substantive complaints that reduce scores in project completion and professionalism.
• A large proportion of reviews are 5-star with enthusiastic language, which warrants mild fake-review scrutiny. However, most reviews contain specific names of technicians (George, Mike, Luis, Gino, Michael, Luigi), specific job descriptions, and unique situational details — this specificity substantially reduces the likelihood of fabricated reviews. No significant fake review pattern detected.
• Recency note: Approximately 25 of 52 reviews are from 2024 or 2023, providing a solid recent data set. However, roughly 15 reviews date from 2012–2017, and business quality and staffing may have changed over that span. Recent reviews are weighted more heavily in scoring.
• One review (2015-12-23) contains only the text 'unknown' and was excluded from scoring as it provides no usable data.

This WW Score is based on 51 usable reviews spanning over a decade, with strong recent representation and HIGH confidence across all four dimensions, making it a reliable indicator of this contractor's typical performance — though prospective customers should note the minority of negative reviews describing responsiveness failures and one allegation of below-code workmanship.
