Find Nearby Plumbers In San Mateo, California

Roto-Rooter receives consistently strong marks for professionalism and responsiveness from individual technicians, with hundreds of reviews praising courteous, knowledgeable, and prompt service. However, pricing is the single most damaging dimension across this dataset, with an enormous volume of reviews describing charges as excessive, deceptive, or wildly inconsistent — including numerous accounts of bait-and-switch quoting, undisclosed fees, and charges for incomplete work. Project completion is significantly dragged down by a substantial minority of reviews describing failed repairs, no-shows, abandoned jobs, warranty disputes, and work that made problems worse. Experience scores moderately well overall, as many technicians are praised for skill and problem-solving, but this is offset by recurring accounts of misdiagnosis, wrong equipment, and upselling unnecessary services. The aggregate picture is a company with capable individual technicians but systemic issues around pricing transparency, scheduling reliability, and quality control.

• DUPLICATE REVIEWS DETECTED: Multiple reviews appear to be exact or near-exact duplicates (e.g., two identical reviews from 'Paul arrived same day...', two identical 'Zach is the man...', two identical 'Based solely off customer service...', two identical 'Easy to schedule and a quick service...', two identical 'Great service. Would highly recommend!', two identical 'Efficient and effective...', two identical 'Excellent with Armando...', two identical 'Very prompt and helpful! Anthony...', two identical 'My name is Antoinette...'). These duplicates inflate positive scores and have been treated conservatively.
• FAKE REVIEW PATTERNS: A large cluster of reviews dated 1996-2001 consist of single-line responses ('NO', 'NOT REALLY', 'ON TIME AND DID THE WORK') with no detail, all rated 5 stars. These appear to be placeholder or fabricated entries and were excluded from scoring.
• BLANK REVIEWS: Approximately 100+ reviews contain no text content but carry 5-star ratings. These were excluded from dimension scoring as they provide no usable data, but their presence inflates the raw star average.
• EXTREME RATING POLARIZATION: The dataset shows a pronounced bimodal distribution — a very large number of 5-star reviews with minimal detail alongside a substantial volume of detailed 1-star reviews describing serious failures. This pattern is consistent with either review manipulation on the positive end or a company with highly inconsistent service quality.
• PRICING COMPLAINTS ARE SYSTEMIC: Pricing complaints are not isolated incidents — they span multiple years, multiple geographic locations, and multiple service types. Charges ranging from $200-$900 for simple drain snaking (15-30 minutes of work) are documented repeatedly. This is a structural business practice issue, not individual technician behavior.
• NO-SHOW AND SCHEDULING FAILURES: A significant number of reviews describe confirmed appointments where technicians never arrived and no communication was provided. This is a recurring operational failure across multiple franchise locations.
• MULTI-FRANCHISE DATASET: Reviews appear to span dozens of different Roto-Rooter franchise locations across the United States. Scores reflect the brand aggregate, not any single location. Individual location quality varies significantly.
• RECENCY NOTE: The majority of reviews with substantive content are dated between 2020-2025, which is within the relevant scoring window. Older reviews (pre-2015) were given reduced weight.

This WW Score of 72.4 is based on a very large dataset (1,456 reviews) and carries HIGH statistical confidence in its directional accuracy, but should be interpreted as a brand-level aggregate across many franchise locations — individual location quality varies substantially, and the systemic pricing and scheduling issues documented here may not apply equally to all franchises.

All Pro Plumbing has a large and highly polarized review base. The majority of reviews praise individual technicians — particularly Ifran, Eddie/Lalo, Brandon, Jerry, and others — for punctuality, friendliness, clear communication, and technical skill. However, a significant and recurring minority of negative reviews describe serious failures: no-shows without notification, ghosting after payment, incomplete work, overcharging (especially of elderly and vulnerable customers), and confrontational or dishonest office staff (particularly referencing 'Michelle' and 'Ifran' in separate negative contexts). Pricing is a mixed picture — many reviewers cite fair or below-market rates, while others describe feeling gouged or misled on costs. Project completion is the most concerning dimension, with multiple credible accounts of abandoned jobs, failed callbacks, and warranty promises that were never honored. The experience dimension scores highest, as technical competence is frequently praised when work is actually completed, but is undermined by instances of misdiagnosis and substandard workmanship.

• SUSPECTED FAKE OR LOW-QUALITY REVIEWS: A cluster of reviews dated 2025-05-09, 2025-05-18, and 2025-05-25 use nearly identical templated language ('arrived on time,' 'fixed the issue quickly,' 'very polite,' 'highly recommend') with no specific technician names, job details, or unique context. These appear to be generic, possibly fabricated 5-star reviews and have been discounted in scoring.
• DUPLICATE REVIEW DETECTED: The review from 'Ifran came and did a thorough inspection...' (grey water leak, toilet) appears verbatim twice with dates 2024-09-19 and 2024-09-20. Similarly, the emergency kitchen sink leak review appears twice on 2024-09-10. These duplicates were counted once each.
• MULTIPLE CREDIBLE ACCOUNTS OF NO-SHOWS AND GHOSTING: At least 15 distinct reviews across multiple years describe confirmed appointments where technicians never arrived and the company did not call to reschedule or apologize. This is a systemic pattern, not isolated incidents.
• FINANCIAL MISCONDUCT ALLEGATIONS: Multiple reviews allege technicians kept cash payments without crediting the company, that promised refunds were never issued, that a warranty water heater check was cashed by the technician personally, and that discounts (first responder, veteran, senior) were promised but not applied. These are serious credibility and trust concerns.
• INCOMPLETE WORK AND WARRANTY FAILURES: Multiple reviews describe jobs left unfinished, work that failed inspection, and warranty promises that were explicitly not honored when customers called back. This pattern significantly depresses the project completion score.
• OFFICE STAFF COMPLAINTS: Multiple reviews specifically name 'Michelle' (described as an owner or manager) as dishonest, confrontational, or unresponsive. This suggests a systemic customer service issue at the administrative level, separate from individual technician quality.
• RECENCY NOTE: The majority of reviews are from 2019 to present, with a strong concentration in 2024-2025. Older reviews (pre-2018) are sparse and have been given reduced weight. The most recent 12 months (mid-2024 to mid-2025) show continued mixed patterns — both strong positive individual technician reviews and continued no-show and communication complaints.
• ENTITY AMBIGUITY: Reviews reference multiple different owners, managers, and operating locations (Bay Area CA, Camarillo CA, McHenry IL, Fresno CA, Reno NV, Texas, Florida, Indiana, and others). It is likely that 'All Pro Plumbing' is a name used by multiple unrelated businesses. Scores reflect the aggregate of all reviews as submitted but users should be aware that this may not represent a single unified company.
• ROAD RAGE INCIDENTS: Two separate reviews (2024 and 2019) describe dangerous or aggressive driving by employees in marked company vehicles. While not directly related to plumbing quality, these reflect on company culture and employee conduct.

This WW Score of 72.1 is based on a very large review set and carries HIGH statistical confidence in its direction, but should be interpreted cautiously due to strong evidence of fake or templated reviews inflating the positive signal, serious and credible recurring complaints about no-shows, financial misconduct, and incomplete work, and likely entity ambiguity across multiple unrelated businesses operating under the same name.

Cabrillo Plumbing scores strongly on professionalism, with an overwhelming number of reviewers across many years praising punctuality, courteous technicians, clean work habits (booties, floor runners, cleanup), clear communication, and advance arrival notifications. Project completion is generally solid — most jobs are finished as promised, with a handful of notable exceptions including one instance of work not strapped to code and a refusal to return to fix it, one drain that re-blocked immediately after clearing, and a few cases where jobs were not completed on the first visit. Experience scores moderately well, with many reviewers citing knowledgeable technicians who diagnosed problems accurately and solved complex issues; however, several credible negative reviews describe misdiagnoses, unnecessary upselling, and at least two cases where a second plumber contradicted Cabrillo's assessment entirely. Pricing is the company's most significant weakness and the primary driver of score suppression — an exceptionally high volume of reviewers across the entire review history explicitly describe prices as very high, outrageous, or double competitors' quotes, with multiple reviewers declining work or switching companies due to cost, and the company's flat-rate pricing model drawing repeated criticism for opacity.

• PRICING CONCERN — HIGH SEVERITY: Pricing complaints are the single most consistent theme across the entire review corpus, spanning from 2005 to 2024. Dozens of reviewers explicitly describe prices as 'outrageous,' 'ridiculously high,' 'double' competitors, or 'triple what they should be.' Multiple reviewers declined work mid-visit due to cost. This is a structural pattern, not isolated incidents.
• WORKMANSHIP CONCERN — MODERATE: At least 3 credible reviews describe misdiagnoses or inaccurate assessments (sewer line, duct/asbestos, toilet parts), where a second plumber contradicted Cabrillo's findings and completed the work at a fraction of the cost. This introduces meaningful uncertainty into the experience score.
• INCOMPLETE/DEFECTIVE WORK — MODERATE: One reviewer reported a water heater not strapped to code with refusal to return and fix it. One reviewer reported a drain re-blocked within days with a dismissive 'customer courtesy' response. One reviewer found a faucet re-assembled incorrectly after service. These are isolated but credible quality-control failures.
• FAKE/USELESS REVIEW FILTERING: A significant number of reviews contain only 'unknown', '.', 'a', 'very well', or single-word text with no usable content. These were excluded from dimension scoring. Additionally, several all-caps reviews from 2005 share identical formatting and date (2005-10-13), which is suspicious and may indicate batch-entered or fabricated reviews. One review (2005-10-13) appears to be a personal relationship reference ('I consider him to be family') rather than a genuine service review. Confidence is not reduced overall due to the large volume of detailed, credible reviews, but these entries were excluded from scoring.
• RECENCY NOTE: The majority of detailed, high-quality reviews are from 2011–2024. Reviews from 2005–2010 are fewer and some appear lower quality or suspicious. The most recent reviews (2022–2024) continue to confirm both the professionalism strengths and pricing concerns, suggesting the pattern is current and stable.
• SERVICE AREA CONCERN: Multiple reviews mention Cabrillo declining to service Oakland zip codes, with at least one reviewer alleging racially motivated redlining. This is a reputational and ethical flag that falls outside the scoring dimensions but is noted here.
• UPSELLING CONCERN: Several reviewers describe feeling pressured into purchasing more expensive options or replacement units when repairs were possible, and at least two describe being told incorrect information that appeared designed to drive higher-cost solutions.

This WW Score is based on a very large review corpus spanning nearly 20 years and carries HIGH overall confidence in the directional findings — Cabrillo Plumbing is a genuinely professional operation with skilled technicians, but its pricing model is a persistent and well-documented concern that materially affects value for money, and isolated but credible workmanship and honesty failures prevent a higher score.

The majority of recent reviews (2025) for Wizard Plumbing are strongly positive, praising punctuality, communication, and courteous technicians, which drives the professionalism score upward. However, the dataset is a mixed-entity set containing reviews for both Wizard Plumbing and Bennett Plumbing, with Bennett reviews spanning 2003–2023 and including several serious complaints about overcharging, abandoned work, poor workmanship, and unresponsiveness. Pricing is a notable weak point: multiple reviewers across both entities flagged high or non-transparent costs, and one reviewer described a bait-and-switch from a $60 promotional price toward an $8,000 estimate. Project completion is significantly dragged down by credible accounts of incomplete work, recurring clogs after service, a technician who left a job site without finishing, and a plumber who caused damage requiring a second contractor to repair. Experience scores moderately well due to many specific mentions of knowledgeable technicians, but is tempered by documented cases of misdiagnosis and failed repairs.

• MIXED ENTITY WARNING: This review set appears to contain reviews for two distinct businesses — Wizard Plumbing and Drain (recent reviews, 2025) and Bennett Plumbing (older reviews, 2003–2023). These should not be scored together as a single contractor profile. The WW Score reflects the blended dataset but may not accurately represent either business individually.
• RECENCY IMBALANCE: The majority of Wizard Plumbing reviews are from 2025 and are overwhelmingly positive. Bennett Plumbing reviews span 2003–2023 and contain most of the negative feedback. Older reviews (pre-2024) should be weighted less, but the negative signals they carry are substantive and cannot be ignored.
• POSSIBLE FAKE REVIEW PATTERN — WIZARD PLUMBING: Several April 10, 2025 reviews reference the same technician (Jonathan) for tankless water heater installations with nearly identical structure, phrasing, and outcomes posted on the same date. This clustering is suspicious and may indicate review manipulation. Confidence in the Wizard Plumbing subset is reduced accordingly.
• BLANK REVIEWS: 8 reviews contained no text (rating only). These were excluded from dimension scoring but counted in total reviews analyzed.
• SERIOUS COMPLETION FAILURES DOCUMENTED: One review describes a technician leaving mid-job without fixing leaks and the owner refusing to send another plumber. Another describes a clog recurring within two weeks, three failed reschedules, an abandoned camera inspection promise, and a multi-thousand dollar upsell that a second plumber resolved for $500. These are credible, detailed accounts that materially lower the project completion score.
• PRICING COMPLAINTS ACROSS BOTH ENTITIES: Multiple reviewers noted prices as high or pricy. One reviewer was charged $300 for a diagnosis without being told the rate upfront. Another was overcharged by $500 relative to the original quote. One reviewer explicitly said they would negotiate on price. These are consistent signals of pricing transparency issues.
• WORKMANSHIP FAILURE — BENNETT: One review describes plumbing work that failed years later at significant cost. Another describes a technician who caused damage that required a second plumber to fix. A third describes toilets not resealed or caulked after wax ring replacement, with the original leak still present.

This WW Score carries moderate-to-limited reliability due to the mixing of two distinct business entities across a 20-year date range, a suspicious clustering of same-day reviews for Wizard Plumbing that may indicate review manipulation, and a meaningful number of detailed negative reviews describing incomplete work, pricing issues, and workmanship failures that substantively offset the volume of generic positive feedback.

All five reviews consistently praise Zeyad and his team for professionalism, communication, and courteous behavior, driving a high professionalism score. Pricing is a notable strength — one reviewer was quoted three times more by a competitor, and multiple others explicitly called rates reasonable or great. Project completion is supported by three reviews that confirm jobs were finished fully and on time, including a complex bathtub plumbing job completed in a single day. Experience is evidenced by the team's ability to handle non-standard setups such as radiant heating systems and cast iron pipe replacement, with reviewers noting technical knowledge and clear explanations. The overall score is tempered by the small review pool of only five reviews, which limits statistical reliability.

• Small sample size of only 5 reviews — WW Score should be treated as preliminary and revisited as more reviews accumulate.
• All 5 reviews are 5-star ratings with no negative feedback of any kind — while the reviews do contain specific details that reduce fake review suspicion, the uniformly perfect ratings warrant mild caution.
• Reviewer names vary slightly across reviews (Zeyad, Vyed, Zay, Zetad) — these appear to be phonetic or spelling variations of the same contractor name rather than a red flag, but noted for transparency.
• One review (2023-11-08) is older than 12 months relative to a mid-2025 evaluation date — given the small pool, all reviews were weighted equally, but recency should be monitored.

This WW Score is based on a small but specific and detail-rich set of reviews; it is directionally trustworthy but should be considered preliminary until at least 10–15 additional reviews are available to confirm consistency.

JD Lopez demonstrates strong professionalism with consistent praise for responsiveness, communication, and collaborative approach across multiple reviews. His technical expertise is well-documented through complex projects involving structural engineering, blueprint interpretation, and multi-trade capabilities. Pricing is generally fair and transparent, though one review notes the project took longer than expected. Project completion is reliable with most jobs finished on time, though one early review (2019) shows a follow-up failure on an estimate. The 1-star review from 2019 regarding non-response to an estimate is a notable weakness that moderates the overall score.

• One 1-star review (2019) indicates failure to follow up on estimate within promised 3-day timeframe—this is a significant professionalism gap that contradicts the overwhelmingly positive pattern
• Most reviews are older than 2 years (5 of 8 reviews predate 2021), limiting recency of data; only 2 reviews from 2021-2022
• Review from 2015 uses somewhat generic phrasing ('just Wonderful,' 'just Great') but includes specific technical details (electrical, plumbing, heating), so not flagged as fake
• No reviews mention hidden charges or pricing disputes, but limited explicit pricing discussion overall (only 4 mentions)

This score should be treated with moderate caution due to limited recent data (only 2 reviews in past 2 years) and the presence of one significant service failure in 2019 that contradicts the otherwise strong pattern; the score reflects strong historical performance but may not fully represent current operations.
