Find Nearby Plumbers In Campbell, California

This contractor has a strong base of loyal, repeat customers who consistently praise individual technicians by name and highlight responsive communication, punctual arrivals, and respectful in-home behavior. However, pricing is a significant and recurring concern across multiple eras of reviews, with multiple customers explicitly describing charges as excessive, inconsistent with quoted amounts, or feeling taken advantage of — including a $1,000 charge for a faucet replacement (parts not included), $900 for toilet guts, $370 for a $7 part, and a $330 diagnostic that escalated unexpectedly. Project completion is generally strong, but there are notable failures including a shower faucet left in worse condition than found, an unresolved gas leak after repeated visits, a missed callback during an emergency, and a lawsuit allegation involving uninsured damage. The professionalism score is tempered by multiple reviews citing rude or dismissive behavior from the owner/office, and one technician making an inappropriate comment upon arrival.

• FAKE REVIEW CONCERN: A cluster of 9 reviews all dated 2025-05-10 and 4 reviews dated 2024-08-13 show suspiciously generic, marketing-style language with no specific job details, technician names, or unique circumstances. Phrases like 'exceeded all my expectations,' 'expertise and precision,' 'personalized care and attention to detail,' and 'encyclopedia' of knowledge are atypical of organic customer reviews. These reviews inflate the overall star rating and have been discounted in scoring.
• FAKE REVIEW CONCERN: Several reviews dated 2024-06-09 also follow a pattern of generic praise with no specifics, suggesting possible coordinated or incentivized review activity around that date cluster.
• BLANK REVIEWS: 14 reviews contained no text — only a star rating. These were excluded from dimension scoring as they provide no usable evidence per scoring rules.
• RECENCY NOTE: A substantial portion of detailed, substantive reviews span from 2009 to 2022. While recent reviews exist, many of the most informative reviews (both positive and negative) are older than 12 months, reducing confidence in current service consistency.
• PRICING CONCERN: Multiple independent, detailed reviews across different years (2015, 2017, 2018, 2019, 2022) describe charges significantly above quoted amounts, upselling of unnecessary work, and fees that did not match the scope of work performed. This is a persistent pattern, not isolated incidents.
• OWNER CONDUCT: At least two reviews explicitly describe the owner or office staff as rude or dismissive when customers raised billing concerns, which is a meaningful professionalism flag.
• UNRESOLVED WORK: One review describes a shower faucet left in a worse state than found with no follow-up from the company after an email complaint. Another describes a gas leak that was never resolved despite multiple paid visits.
• LAWSUIT ALLEGATION: One review (2009) alleges the owner caused property damage while uninsured and was avoiding legal service. While old, this is a serious flag that warrants mention.
• POSSIBLE MULTI-ENTITY CONFUSION: Several reviews appear to reference different business entities (M&R Plumbing, Mr. Plumbing, Mr. Reliable Plumbing and Heating) and different geographic markets (Chicago suburbs vs. San Jose/Bay Area California). Some reviews referencing 'Michael Ra' and California locations may belong to a different business entirely, which could contaminate the dataset.

This WW Score carries moderate-to-high structural reliability due to the large review volume, but should be interpreted cautiously given strong evidence of fake or incentivized review clusters, a persistent multi-year pricing complaint pattern, possible cross-business review contamination, and a meaningful number of blank reviews that provide no scoring data.

Alpha Omega Plumbing and Septic has a large and mixed review base spanning multiple years and what appears to be at least two distinct service areas and possibly two different business entities operating under the same or similar name — one focused on septic/plumbing in the high desert/Southern California area and one focused on water heater warranty work in the San Jose/Bay Area (associated with 'Frank'). Professionalism scores are dragged down significantly by a recurring and serious pattern of unanswered calls, no-shows, and poor communication, particularly in the Frank/Bay Area reviews, with at least 8 reviews explicitly citing failure to return calls or missed appointments. Pricing feedback is mixed — several reviews praise competitive or fair pricing, while others cite overpricing or surprise charges, resulting in a below-average score. Project completion is moderate; many jobs were completed well and quickly, but there are credible accounts of incomplete work, incorrect diagnoses, and one instance of damage caused during service. Experience scores are similarly mixed — many reviewers praised technical knowledge and skill, but several credible negative reviews describe misdiagnosis, incorrect installations, and a failure to identify basic issues.

• POSSIBLE MIXED ENTITY: Reviews appear to represent at least two distinct operational contexts — a septic/plumbing company in the Southern California/High Desert area and a Bay Area water heater warranty service associated with 'Frank.' Scores may reflect blended performance across different teams, locations, and service types, reducing reliability.
• RECENCY CONCERN: A significant portion of reviews (roughly 40+) are dated prior to 2022, with many from 2012–2017. These older reviews may not reflect current service quality. More recent reviews (2024–2025) are weighted more heavily but represent a smaller share of total data.
• RESPONSIVENESS PATTERN — NEGATIVE FLAG: At least 8 separate reviews explicitly describe Frank/Alpha Omega failing to return phone calls or respond to messages over multiple days or weeks. This is a consistent and credible pattern, not isolated incidents.
• BLANK REVIEWS: At least 6 reviews contained no text and only a star rating. These were excluded from dimension scoring but counted in total reviews analyzed.
• FAKE REVIEW SUSPICION — MODERATE: Several 5-star reviews from the 2024–2025 septic service cluster are very brief and generic (e.g., 'Good service and work,' 'Very good Work I recommend these company,' 'Great customer service and their staff are amazing'). While not conclusive, the volume of short, undetailed 5-star reviews with identical dates warrants caution.
• PRICING CONCERN: One review explicitly cited a $950 overcharge for septic pumping compared to a competitor. Another review described surprise charges added at time of payment. These are credible pricing integrity concerns.
• WORKMANSHIP CONCERN: One detailed review described Alpha Omega caving in a seepage tank during a certification inspection and then claiming replacement was needed — a second opinion contradicted this. Another review described an incomplete garbage disposal installation that caused subsequent water damage.

This WW Score is based on a large volume of reviews (97 total) with high mention counts across all four dimensions, giving it statistical weight, but reliability is meaningfully reduced by the likely blending of two distinct business entities or service teams, a significant proportion of older reviews, a documented pattern of non-responsiveness, and moderate suspicion of generic 5-star padding in recent reviews — treat this score as a cautious baseline rather than a definitive quality indicator.

Wenger Plumbing demonstrates strong technical expertise and professionalism, with consistent praise for knowledge, responsiveness, and workmanship across multiple reviews. However, the score is tempered by three significant negative reviews citing billing disputes, incomplete work, and project abandonment. The 1-star reviews from 2017, 2016, and 2011 raise concerns about pricing transparency and project follow-through, particularly regarding overbilling practices and failure to honor commitments. While the majority of reviews are positive and older (pre-2018), the pattern of complaints about completion and pricing prevents a higher overall score.

• Three 1-star reviews with serious allegations: overbilling/double-billing (2017), project abandonment due to prioritizing larger jobs (2016), and incomplete work (2011). These are not isolated complaints but suggest systemic issues.
• Significant recency bias: 10 of 14 reviews are from 2012-2021, with most positive reviews clustered in 2014-2021 and negative reviews spread across 2011-2017. No reviews from past 3 years limits ability to assess current practices.
• Pricing dimension shows conflicting signals: multiple reviews praise 'reasonable pricing' and 'best price,' but one detailed 2017 review documents aggressive billing practices (charging for travel time, double-billing crew hours, charging for warranty parts). This suggests pricing practices may have changed or vary significantly by job type.
• Project completion concerns: one review explicitly states work was left undone and incorrectly completed; another describes year-long delays and scheduling conflicts. These are material failures despite overall positive sentiment.

This score should be treated with caution due to conflicting evidence and lack of recent reviews. While technical expertise appears strong, the documented billing disputes and project completion failures are serious enough to warrant direct inquiry before hiring. The absence of reviews from the past 3 years makes it impossible to assess whether issues have been resolved.

This contractor operates as two distinct business entities with dramatically different performance profiles. Air & Plumbing Systems (recent reviews, 2021-2025) demonstrates exceptional professionalism, responsiveness, and technical expertise with 35 consistently positive 5-star reviews. However, McMahon Plumbing (older reviews, 2008-2014) shows severe deficiencies in customer service, professionalism, and project completion with multiple 1-star reviews citing rude staff, abandoned jobs, and poor communication. The blended WW Score of 72.8 reflects this polarization: strong marks for experience and professionalism from Air & Plumbing offset by critical failures in professionalism and completion from McMahon's historical record. Recency heavily favors Air & Plumbing, suggesting significant operational improvement or rebranding.

• CRITICAL: Two distinct business entities analyzed. Air & Plumbing Systems (35 reviews, 2021-2025, all 5-star) vs. McMahon Plumbing (38 reviews, 2008-2014, mixed 1-5 star). These appear to be the same company under different names or a merger/acquisition scenario.
• McMahon Plumbing shows severe professionalism failures: multiple reviews cite rude receptionists, staff walking off jobs, hanging up on customers, and dismissive attitudes. One review documents a receptionist telling a customer 'that's an obstacle. life is full of obstacles. Deal with it' before hanging up.
• Project completion concerns with McMahon: documented cases of incomplete work, no-shows, unprepared technicians, and refusal to complete jobs after customer complaints.
• Air & Plumbing Systems reviews show suspicious consistency: 35 consecutive 5-star reviews with highly detailed, specific praise. While not identical phrasing, the uniformity and absence of any critical feedback is atypical. However, reviews span 4+ years and include specific names (Mark, Caesar, Daniel, Sergey, Curtis) and detailed project descriptions, suggesting authenticity.
• Pricing data limited: only 12 mentions across 73 reviews. Air & Plumbing reviews consistently mention 'competitive,' 'fair,' or 'reasonable' pricing; McMahon reviews cite high labor rates ($100/hr, $85 service fees, $197 for outlet installation deemed excessive).
• Temporal divide is stark: no reviews between June 2014 and June 2021. This 7-year gap suggests possible business closure, rebranding, or data collection gap.
• McMahon Plumbing appears to have operated as third-party installer for Western Appliance, which may explain concentration of negative appliance installation reviews.

This score should be treated with CAUTION due to the two-entity problem: Air & Plumbing Systems (recent, uniformly positive) and McMahon Plumbing (older, mixed-to-negative) appear to be the same business. If evaluating current service, Air & Plumbing Systems alone scores approximately 92/100 with HIGH confidence across all dimensions. If McMahon Plumbing is still operating under that name, the blended score of 72.8 is more accurate but reflects a company with serious historical customer service issues. Recommend clarifying current business name and confirming whether McMahon operations have ceased.

Down Under Plumbing shows mixed performance across a very small review sample. Professionalism is their strongest dimension, with multiple mentions of punctuality, cleanliness, and responsiveness. However, a critical 2010 review reveals serious concerns about pricing transparency and scope management—work was performed without customer approval and billed at 230% of the original quote. The two oldest positive reviews (2005, 2014) lack specificity and may not reflect current operations. The company's profile reportedly shows 'closed' status, raising questions about current business viability. With only 4 reviews spanning 11 years, this score carries substantial uncertainty.

• RECENCY CONCERN: Reviews span 2005–2016 with significant gaps. Most recent review is 8+ years old; current operations unclear.
• PROFILE STATUS: One review explicitly states the company profile shows 'closed,' yet they claim recent business activity. This inconsistency requires verification.
• PRICING RED FLAG: 2010 review documents serious billing dispute—work performed without approval and invoiced at 230% of bid. This is a material ethical and business practice concern.
• SMALL SAMPLE SIZE: Only 4 reviews total. Statistical reliability is very low.
• GENERIC PRAISE: Two oldest reviews (2005, 2014) contain minimal specific detail and use generic language ('top notch,' 'outstanding'). Cannot verify authenticity.
• POTENTIAL REPUTATION MANAGEMENT: 2010 review suggests company may have deleted negative reviews by closing/reopening profile.

This score should be treated with significant caution. The sample size is too small (4 reviews), the time span is too wide (11 years with no recent data), and one critical review documents a serious billing and communication failure that directly contradicts the positive reviews. The company's current operational status is unclear. Do not rely on this score for high-stakes decisions without additional current references.

Economy Rooter demonstrates significant inconsistency in service quality. While many customers praise individual technicians (George, Sergio, Alex, Jose, Kevin) for professionalism, efficiency, and technical skill, the company suffers from serious systemic issues. Major concerns include: unreliable follow-up and callback responsiveness, aggressive upselling of unnecessary services (particularly with warranty company assignments), poor communication and scheduling reliability, and documented instances of incomplete work requiring multiple callbacks. The company performs better on direct-hire jobs but significantly worse when assigned through home warranty companies (AHS, AHW) or big-box retailers (Lowe's, Home Depot), suggesting a two-tier service model. Pricing transparency is a persistent complaint, with customers reporting surprise charges and inflated quotes.

• SYSTEMIC PATTERN: Multiple reviews (at least 8) document poor responsiveness and no-shows when assigned through home warranty companies (AHS, AHW, American Home Shield). This suggests deliberate deprioritization of warranty work.
• UPSELLING PATTERN: At least 6 reviews document aggressive upselling of unnecessary services or inflated charges for minor work (e.g., $385 to remove a shower handle, $250 for 15-minute connection modification, $440 in 'additional services' for water heater install, $600+ quote for water softener install).
• CALLBACK FAILURES: Multiple documented instances of missed appointments, no-shows, and failure to return calls despite promises. At least 7 reviews explicitly mention this issue.
• INCOMPLETE WORK: Several reviews document work that failed inspection, required multiple callbacks, or was left incomplete (water heater installations, drain work, gas leak not detected).
• MANAGEMENT RESPONSIVENESS: Multiple reviews describe rude, dismissive, or evasive behavior from office staff and management (particularly 'Sevdet' and 'Sev'), including hanging up on customers and refusing to provide service.
• WARRANTY COMPANY FRAUD ALLEGATION: One detailed review alleges the company changed diagnosis to AHS to deny warranty coverage after initially approving replacement, then offered inflated out-of-warranty pricing.
• QUALITY CONTROL: At least 3 reviews document safety issues (gas leak not detected, improper compression fitting installation, failed inspection) or defective parts delivered (missing serial number on water heater).
• RECENCY NOTE: Most negative reviews cluster around warranty company assignments (2023-2024) and Lowe's/Home Depot contracts (2017-2022). More recent direct-hire reviews are mixed but include serious complaints about responsiveness and incomplete work.

This WW Score of 68.2 should be treated with caution despite HIGH overall confidence. The score reflects a company with highly variable performance: excellent individual technician quality on direct-hire jobs, but severe systemic failures in responsiveness, follow-up, pricing transparency, and work completion—particularly when assigned through warranty companies or retailers. The company appears to operate two distinct service models with markedly different standards. Customers should expect inconsistent experiences and should avoid using this company for warranty-assigned work.
